2. Important Notes

2.1 Electrical Safety

The system must be connected to a stable AC power source of 220 V ±5%, with a frequency of 50 Hz or 60 Hz. Ensure proper grounding, with a grounding resistance of ≤4 Ω. Do not use the equipment if the power connections are loose or the cables are damaged.

2.2 Environmental Safety

Avoid using the device in environments where humidity exceeds 70% (no condensation) or where the temperature is outside the range of 0–35°C. The optimal operating temperature is 25±2°C.

Both the control room and the darkroom must be kept dry, well-ventilated, free of dust, and free of corrosive gases, with an ambient temperature of 15–35°C and a relative humidity of ≤85%;

Keep the equipment away from strong magnetic fields, strong electric fields, or corrosive gases;

2.3 Darkroom Operating Procedures

2.3.1 Darkroom Description

The interior of the darkroom must be completely painted matte black—that is, a non-reflective, pure black—including all walls, ceilings, floors, partitions, doors, and so on. A small number of components, such as lighting fixtures, air conditioning units, and power switches, may not be painted black, provided they do not appear in the optical path between the Goniophotomoeter’s main unit and the photometric probe;

Once the equipment has been installed and commissioned, do not move any hardware within the darkroom, including the main unit base, the photometer probe base, the orientation of the photometer probe, or the orientation of the Optical Fiber; doing so may result in inaccurate test results;

When putting the darkroom into use, please keep it as dust-free as possible;

Ensure that the darkroom door is closed and that no external light enters the darkroom when the interior lighting is turned off.

2.3.2 During Use

Remove your shoes or put on shoe covers when entering the darkroom to prevent dust from being brought inside;

Set the air conditioner in the darkroom to 25°C and switch it to a gentle breeze setting to prevent strong air currents from affecting the test results;

The sample luminaire must be securely mounted to prevent it from falling and damaging the Goniophotomoeter during testing;

Do not place any objects on the Goniophotomoeter unit or within its range of rotation to avoid damaging the Goniophotomoeter;

During testing, the darkroom must remain sealed to prevent external light from interfering with the test results.

2.3.3 When Not in Use

Keep the darkroom closed when not in use; unauthorized persons are not allowed to enter, to prevent dust from getting into the darkroom.

2.4 Standard Lamp Operating Procedures

The standard lamp has a lifespan of one year and is used only during installation and commissioning to calibrate photometric probes and Spectroradiometers. If the conditions of your darkroom remain unchanged (such as the color of the interior coating, internal dimensions, and the location and orientation of hardware), recalibration is not necessary;

If your laboratory requires annual calibration of the darkroom, you may purchase a new standard lamp;

The standard lamp is hot immediately after use; do not touch it. Allow it to cool for 10 minutes before returning it to the lamp case;

Avoid getting stains on the surface of standard light bulbs; if stains are present, they can no longer be used as standard lights;

The standard lamp used in the darkroom is a directional standard lamp, meaning that its color and luminous intensity data are specific to a particular direction. Do not remove the standard lamp bulb from its holder; doing so will render the standard lamp invalid.

2.5 Optical Fiber Operating Procedures

Optical Fiber must not be bent excessively (minimum bend radius ≥ 10 cm). Do not step on or squeeze the Optical Fiber, as this may damage it and cause abnormal test results.

2.6 Other

For matters not covered in this manual, please proceed with caution or contact us.

4.3.2.2 Installing the Near-Field Bracket

However, the mounting end of the near-field bracket can be rotated to a horizontal position to facilitate installation.

Figure 31

Note: Before all components are installed on the spindle, the weight distribution at both ends is uneven; therefore, the spindle may not rotate when controlled by the software. This manifests as the software freezing with no response and the spindle failing to rotate. If this occurs, turn off the power to the LSG-6000 Goniophotomoeter main unit, wait one minute, and then turn it back on. Apply a constant force to push or pull the spindle, then simultaneously use the software to control its rotation. Ensure that the external force you apply is in the same direction as the spindle’s rotation. Throughout the process of installing the spindle accessories, you may need to repeat this procedure several times to complete the installation.

Be sure to thread the reserved cable through the holes in the near-field bracket. Then, secure all screw holes firmly using Allen screws.

5. Calibration of darkroom equipment (Each step must be performed carefully and thoroughly; otherwise, it may result in incorrect calibration data and abnormal test results.)

5.1 Single-Line Laser Calibration

Turn on the single-button laser power switch.

Figure 57

The single-character laser was turned on.

Figure 58

Rotate the main shaft of the Goniophotomoeter to the position shown in the figure below to facilitate the following steps.

Figure 59

Please hold the lamp shaft steady and loosen these two screws again.

Figure 60

Hold the lamp shaft steady and slowly rotate it 180 degrees clockwise in the direction shown in the figure below.

Figure 61

Note: A counterclockwise stop has been installed at this point on the lamp shaft, so it can only be rotated clockwise.

The straight laser beam from the main unit will then trace a semicircular path on the wall opposite the darkroom. You can attach a sheet of white paper to the wall and trace the laser path with a water-based marker. If the radius of the semicircle is very small (for example, 0.5 centimeters) or even close to a single point, no adjustment is necessary. If the radius of the semicircle is larger, adjust the four small Allen screws around the straight-line laser to position the laser spot at the center of the semicircle.

Figure 62

Once adjusted, hold the lamp shaft steady and rotate it 180 degrees counterclockwise to return it to its original position, while rechecking that the straight laser beam’s path meets the requirements. After debugging, ensure that all four small Allen screws on the straight laser are fully tightened. Rotate the lamp shaft back to its initial position and hold it steady, then fully tighten the two large screws on the side of the main unit to secure the lamp shaft.

5.2 Adjusting the Host’s Position

First, move the main unit to its approximate location based on the darkroom blueprints. Then, fine-tune the position of the main unit and adjust the height of all the large screws on the support beam to adjust the main unit’s tilt angle.

Figure 63

Ensure that the host’s final position meets the following two conditions.

① The single-line laser passes through the exact center of the light-transmitting holes in all the partitions.

Figure 64

② The light shaft must be vertical (with no tilt in any direction); you can use a cross-line laser to verify this.

Find the cross-hair laser and the tripod.

Figure 65

Remove the cross-line laser and the batteries. Insert the batteries into the cross-line laser. The power switch is located on the side of the device. Turn the switch to the “unlock” position to turn on the device.

Number	Note
①	Power switch: Move it to the “Unlock” position to turn on the power.
②	VH refers to vertical and horizontal laser switches, respectively

Figure 66

Note: The cross-line laser is self-leveling. If it is not self-leveled, an audible alarm will sound. This may be due to an uneven surface or an improperly set up tripod. Please ensure that the cross-line laser remains self-leveled at all times during use.

5.3 Adjust and Secure the Far-Field Luminance Probe Mount

There is a small mirror inside the standard light box; remove it.

Figure 67

Figure 68

Temporarily remove the far-field photometer probe, then install the small mirror in the position shown in the figure below.

Figure 69

Please adjust the position of the far-field probe bracket. Then remove the screws shown in the figure below.

Figure 70

You can adjust the height of the probe bracket by turning the two pairs of large screws here.

Figure 71

The goal is to have the straight laser beam from the host unit strike the exact center of the small mirror, so that the reflected straight laser beam travels back along the same path.

Figure 72

Once the location has been determined, use expansion screws to secure the probe bracket base to the floor.

Figure 73

Once it is securely fastened, double-check that the straight laser beam coming from the main unit hits the small mirror and that the reflected beam follows the same path back. After adjusting and securing it, you can remove the small mirror.

Reinstall the far-field photometric probe. Then attach the small mirror to the probe, as shown in the figure below.

Figure 74

5.4 Setting the Spindle’s 0-Degree Position

Number	Note
①	Still opting for a far-field photometric probe
②	Enter 0
③	Check the “Synchronize Axis” box
④	Click any button to simultaneously rotate the main shaft and the synchronous shaft (i.e., the far-field photometric probe) to the 0-degree position; at this point, the reflector should be directly below the main shaft.

Figure 75

Use the cross-hair laser to verify that the main axis is perpendicular to the lamp axis. If not, use the following method to fine-tune the main axis until it is perpendicular, then set it to 0 degrees.

Number	Note
①	Still opting for a far-field photometer
②	Please always check the “Sync Axis” box.
③	Based on the actual situation, enter a small angle, such as 1, 0.5, 0.1, 0.05, etc.
④	Based on the actual situation, choose a direction to rotate. Repeat steps ③ and ④ until the spindle is rotated to a vertical position.
⑤	Click to set the current angle to 0 degrees. Password: LISUNGROUP

Figure 76

5.5 Adjusting the Direction of the Reflector and the Far-Field Photometric Probe

Number	Note
①	There is a switch at the top of the lamp post; turn the switch on.
②	A straight laser beam will be projected downward from the center of the lamp shaft.

Figure 77

You need to adjust the three sets of screws on the fixed rearview mirror to adjust the mirror’s reflection angle.

Figure 78

At the same time, you’ll need to adjust the screws on the far-field photometer probe bracket to change the height and orientation of the far-field photometer probe.

Figure 79

This causes the straight laser beam emitted downward from the lamp shaft to strike the reflector; after being reflected by the reflector, it strikes the exact center of the small mirror on the far-field photometer probe, and after being reflected once more, it returns along the same path.

Figure 80

Figure 81

Once calibration is complete, all screws should be fully tightened. Remove the small mirror attached to the far-field photometric probe, and reinstall the far-field probe sleeve and housing.

After cleaning the equipment with a dry, soft cloth, reinstall all covers, screws, and other parts.

Then, cover all equipment with dust-proof cloths and clean the darkroom and control room. Once everything has been cleaned, turn on all the equipment.

6. Calibration

6.1 Installation and Commissioning of Standard Lamps

6.1.1 Installation of Standard Lamps

Find the standard lamp and its extension pole.

Figure 90

Assemble the standard lamp as shown in the figure below, and install the small mirror as well.

Figure 91

Go to the software angle control interface and rotate the C-axis to the 0-degree position.

Figure 92

Attach the standard lamp to the extension rod, and then mount the extension rod to the lamp shaft.

Number	Note
①	There is a slot on the extension rod. After removing the bolt from this slot, insert the extension rod all the way to the bottom and then loosen the bolt; this will lock it in place and prevent it from falling out.
②	Turn the screw by hand; turning it counterclockwise loosens it, and turning it clockwise tightens it.

Figure 93

Secure the standard lamp in the orientation shown in the figure below.

Figure 94

There are four terminals on the light fixture. Please follow the diagram on the light fixture: short-circuit the red and yellow terminals together, and short-circuit the blue and black terminals together, then connect the red and blue wires to the standard light fixture power cord.

Figure 95

Note: The connection method for the power supply of the standard lamp and the sample lamp is the same.

6.1.2 Adjusting the Orientation of the Standard Lamp

Number	Note
①	Turn on the switch here
②	Use the up/down switch to adjust the lamp shaft—that is, the height of the standard lamp.

Figure 96

The three screws on the standard lamp bracket allow you to adjust the pitch angle of the standard lamp.

Figure 97

The standard lamp should be adjusted so that the cross-shaped laser beam is directed at the center of the small mirror, and the horizontal and vertical laser beams reflected from the mirror coincide exactly with the original cross-shaped laser beam.

Figure 98

Based on our experience, follow these steps for calibration: First, adjust the standard lamp to the appropriate height. The vertical reflected laser can be calibrated by rotating the extension rod, while the horizontal reflected laser can be calibrated by adjusting the standard lamp’s pitch. After calibration, the center height of the standard lamp may change, requiring you to readjust its height. Repeat this process until the crosshair laser is projected onto the center of the small mirror, and the reflected horizontal and vertical laser beams perfectly align with the original crosshair laser.

Once the standard lamp is properly aligned, carefully remove the small reflector, taking care not to alter the alignment of the standard lamp during removal. Then turn off the cross-hair laser.

6.2 Calibration of the Far-Field Photometric Probe

All standard lamps are constant-current DC light sources. Set the AC/DC switch on the 19-inch Standard Instrument Cabinet to DC.

Close the darkroom door and make sure that all light sources in the darkroom are turned off, except for the standard lamp.

Number	Note
①	Selecting a Far-Field Photometric Probe
②	Luminous flux calibration—our software includes this option, but current standard practices require the use of luminous intensity calibration, and the standard lamps included in our standard configuration are also luminous intensity standard lamps. Therefore, there is no need to use luminous flux calibration at this time.
③	Light Intensity Calibration Method
④	Refer to the standard lamp calibration certificate and enter its calibrated luminous intensity value.
⑤	Click to Start
⑥	The software will automatically calculate the test distance.
⑦	To verify the results, click “Check,” and the software will display the current measured light intensity value. The measured light intensity value should match the calibrated light intensity value.
⑧	Click “OK” to save and exit.

Figure 103

Note: The test distance for the far-field photometric probe is the distance from the center of the Goniophotomoeter to the reflector, plus the distance from the reflector to the surface of the far-field photometric probe. The distance calculated by the software should be close to the actual distance; an error of 1% or less is considered normal. If the error is too large, please refer to Section 2.3.1 to verify that the darkroom is functioning properly, and refer to Chapter 5 to review the calibration procedure.

6.3 Calibration of Near-Field Photometric Probes

The reference lamp remains lit and stable. Enter the angle control interface.

Number	Note
①	The C-axis is still at the 90-degree position
②	Select the near-field photometer probe and rotate it to the 90-degree position . Note: When calibrating the near-field, you do not need to worry about the position of the synchronization axis.

Figure 104

Once the lamp has been rotated to the target position, the round hole in the standard lamp bracket is directly aligned with the near-field photometer probe.

Figure 105

Go to the photometric probe calibration interface and select the near-field photometric probe. The remaining steps are exactly the same as those for calibrating the far-field photometric probe; please refer to Section 6.2.

Figure 106

Note: The standard distance for the LSG-6000S near-field photometric probe is 1.25 m, and the standard distance for the LSG-6000 near-field photometric probe is 1.5 m.while the standard measurement distance for the LSG-6000B and LSG-6000L near-field photometric probes is 1.75 m.

6.4 Calibration of The Spectroradiometer (if applicable)

The reference lamp remains lit and stable. Enter the angle control interface.

Number	Note
①	The C-axis is still at the 90-degree position
②	Select the spectroradiometer and rotate it to the 90-degree position.

Figure 107

Once the device has been moved to the target position, the circular opening in the standard lamp mount should be aligned directly with the Optical Fiber path of the Spectroradiometer.

Click to open the Spectroradiometer calibration interface.

Figure 108

Number	Note
①	For the points accumulation time, be sure to always select “Automatic.”
②	First, click “Sampling.” Once sampling is complete, the corresponding curve will appear on the screen. After sampling is complete, the “Calibrate” button will become clickable.
③	Refer to the standard lamp calibration certificate and enter its calibrated color temperature value.
④	Click “Calibrate.” Once calibration is complete, the corresponding curve will appear on the screen.
⑤	Click OK to save and exit.

Figure 109

After calibration is complete, you can turn off the standard lamp using the software. Since the standard lamp becomes quite hot during use, wait for it to cool down before placing it back in its packaging and storing it safely along with the extension rod.

6.5 Calibration and Maintenance

No changes in the darkroom	If there have been no changes to the computer, recalibration is not necessary.
	No changes were made to the computer; simply unplug and replug the communication cable or reinstall the Goniophotomoeter software—no need to recalibrate.
	If you replace your computer or reinstall the operating system, the photometric probe does not need to be recalibrated; simply enter the previous measurement distance and save it. However, the Spectroradiometer does need to be recalibrated (if you do not have the means to recalibrate it, please contact us to restore the calibration data).
Changes in the Darkroom	The structure of the darkroom remains unchanged; however, after prolonged use, the interior paint may fade or peel. Depending on how well you maintain the darkroom and your requirements for the accuracy of test results, you may repaint the darkroom periodically. After repainting, the darkroom must be recalibrated.
	There has been a change in the darkroom configuration, so recalibration is required.

7. Preparations Before Testing

7.1 Lamp Selection and Aging

Select representative luminaires for testing that comply with national or corporate standards; new luminaires must undergo aging treatment (for LED luminaires, a 24-hour aging period is recommended);

Check that the light fixture has no visible damage, that the internal wiring is properly connected, and clean any stains from the surface of the fixture.

7.2 Introduction to Test Modes

C-Gamma Mode: Suitable for most lighting fixtures, such as streetlights, downlights, panel lights, and plant grow lights.

Figure 109.1

Beta Mode: Suitable for spotlights, floodlights, and similar fixtures; requires installation of an auxiliary arm.

Figure 109.2

Alpha Mode: Suitable for automotive lights and signal lights.

Figure 109.3

Note: The LSG-6000 series can perform C-Gamma and B-Beta tests. For A-Alpha testing, a Type A Goniophotomoeter is required; please contact us if needed.

8. C-Gamma Test

8.1 Luminous Intensity Distribution Test

8.1.1 Installing and Turning On the Light Fixture

8.1.1.1 Light Fixture Installation

We have two C-Gamma test fixtures; this procedure uses the cross-shaped fixture as an example.

Number	Note
①	Large cross-shaped clamps are used for various types of lighting fixtures
②	E27 Fixture for Testing Globe Bulbs

Figure 110

Figure 111

Attach the fixture to the Goniophotomoeter using the same method as for installing the standard lamp extension rod.

Figure 112

Adjust the height of the light axis and the cross-shaped clamp so that the light-emitting surface of the sample is level with the cross-shaped laser.

Figure 113

Caution is required when installing directional luminaires. When the angle of the Goniophotomoeter’s C-plane is 0 degrees, according to streetlight installation standards, the light pole should face the Goniophotomoeter’s main unit; when the angle of the Goniophotomoeter’s C-plane is 0 degrees, according to industry standards for linear luminaires, the light pole should be perpendicular to the Goniophotomoeter’s main unit.

Once the light fixture is installed, you can turn off the crosshair laser.

8.1.1.2 Lighting the Lamps

Connect the power cord to the luminaire under test. The connection method for the luminaire under test is the same as that for the standard luminaire; refer to Section 6.1.1.

Adjust the cabinet switch according to the parameters of the luminaire being tested.

Number	Note
①	If the sample luminaire is powered by AC, switch to the AC position; if it is powered by DC, switch to the DC position.
②	Internal/External Sampling Switch for Electrical Parameters. External sampling uses a four-wire configuration, which provides more accurate voltage readings. Unless there are specific requirements, please set this switch to the external sampling position.

Figure 114

If the sample luminaire is AC-powered.

Number	Note
①	Select AC Power
②	Based on the sample parameters, enter the correct voltage and frequency.

If the sample luminaire is DC-powered.

Number	Note
①	Select a DC Power Supply
②	Based on the sample parameters, enter the correct voltage and current.
③	Select the output mode: CC stands for constant current, and CV stands for constant voltage. If you select constant current, you need to enter the sample’s rated current value; for voltage, simply enter the maximum output voltage of this DC power supply. If you select constant voltage, enter the sample’s rated voltage; for the current value, simply enter the DC power supply’s maximum output current. Note: If your DC power supply model is DC3010, its maximum output voltage is 30 V and its maximum output current is 10 A.

Figure 116

The software offers two methods for turning the sample lamp on and off, and users can choose either one.

Number	Note
①	If you check the “Auto-On” and “Auto-Off” options, the software will automatically power on the sample according to the selected power source and the entered electrical parameters when the test begins, and will automatically cut off the sample’s power when the test ends.
②	If the “Auto On” and “Auto Off” options are not checked, you can still click this button; the software will power on the sample based on the selected power source and the entered electrical parameters. Clicking this button again will cut off the power to the sample.

Figure 117

8.1.2 Preheating Parameter Settings

Number	Note
①	If “Preheat” is checked, the software will preheat the luminaire according to the configured preheat parameters when the test begins, and the test will start automatically once preheating is complete. If “Preheat” is not checked, the software will begin the test immediately.
②	Preheating Parameter Settings

Figure 118

Click “Preheat Parameter Settings.”

Number	Note
①	Warm-up Duration Setting: The purpose of the warm-up is to allow the light fixture to remain on for a period of time until its luminous and chromatic parameters stabilize, after which testing begins automatically.
②	Sampling interval: The software will automatically take samples at the set interval throughout the entire warm-up period to obtain real-time data. We recommend setting the interval to 5 seconds or longer.
③	If checked, the test will automatically skip the remaining warm-up time and begin once the light fixture has stabilized; if unchecked, the warm-up will complete according to the set duration before the test begins.
④	Definition of a luminaire’s steady state. If the values are set to 20 and 0.5%, the luminaire is considered to be in a steady state if the variation in the parameter does not exceed 0.5% over the past 20 minutes.
⑤	You can select which parameters the software should use to determine whether a light fixture is stable: optical parameters, electrical parameters
⑥	The software will save the change curves for the selected parameters during the warm-up process in the test report.
⑦	Once you’ve finished configuring the settings, click OK to save and exit.

Figure 119

8.1.3 Configure Test Parameters and Start the Test

Click “Start Test.”

Figure 120

Go to the test parameter settings screen.

Number	Note
①	Lighting fixture types: indoor lights, outdoor lights, or plant grow lights—these three types of lighting fixtures are subject to C-Gamma testing.
②	Select whether the luminaire is symmetrical. Unless there are specific requirements, select the first option, “asymmetrical,” regardless of whether the luminaire being tested is symmetrical or not (to obtain the luminaire’s actual data).
③	C-plane angle range: Select 0 to 180 degrees; no modification is needed. For data ranging from 180 to 360 degrees, the software will automatically convert the C-plane angle intervals. For symmetrical luminaires, such as indoor lights, you can select a larger interval, such as 30 degrees; for asymmetrical luminaires, such as streetlights, you can select a smaller interval, such as 10 degrees. The smaller the angle increment, the higher the testing accuracy, but the longer the testing time. If time permits, we recommend selecting a smaller angle increment.
④	Gamma plane angle range: If the sample’s light irradiation angle exceeds 180 degrees (e.g., incandescent bulbs), select -180 degrees to 180 degrees; if the sample’s light irradiation angle is less than 180 degrees (e.g., panel lights), you may select a Gamma plane angle increment of -90 degrees to 90 degrees. Unless there are special requirements, a 1-degree increment is sufficient. Different angle increments do not affect the test speed.
⑤	In the vast majority of cases, you should choose to use a far-field photometer. Near-field photometers are intended only for light sources with very low luminous intensity, such as a single LED.
⑥	For routine testing of standard lighting fixtures, select “Normal Speed”; if the lighting fixture being tested has an extremely narrow beam angle, select “Slow Speed” to obtain more accurate test results; for expedited testing, select “Fast Speed.”
⑦	Fixed Range: If you are consistently measuring the same type of light and the luminous intensity data does not vary significantly, you can check this box to save time. If you have ample time or frequently test lamps with varying luminous intensities, it is recommended that you leave this box unchecked. In this case, the photometric probe will automatically select the appropriate range for each lamp. Continuous Scan Mode is suitable when the angular interval on the Gamma plane is between -180 degrees and 180 degrees. During the test, when the Gamma angle approaches ±180 degrees, while simultaneously rotating the C-axis to the next scanning position—that is, the Gamma axis rotates continuously without stopping to save time. If you have ample time, we recommend leaving this option unchecked.
⑧	To set the monitoring angle during the lamp’s warm-up phase, simply set it to (0, 0).
⑨	Normalization refers to the decision of whether to apply a uniform value to the first row of data in the luminous intensity table of a test report; certain standards, such as the U. S. streetlight standard, may require you to perform a similar adjustment. There are three options: no normalization, normalization to the maximum value (which will slightly increase the luminaire’s total luminous flux), and normalization to the average value (which leaves the luminous flux essentially unchanged).
⑩	If you need to remove all stray light outside a specific angle, check this option and enter the desired angle . For example: If you check this option and enter 60, data outside ±60 degrees of the luminaire’s Gamma plane will automatically be set to 0.
⑪	Enter the number of light sources in the luminaire and the rated luminous flux of each light source. If you do not know this information, you may leave it blank; it will not affect the test results.
⑫	Enter the dimensions of the sample’s light-emitting surface. For indoor lighting fixtures, the software requires this data to calculate the luminance limit curve, UGR, and other parameters.
⑬	Enter information about the sample luminaire
⑭	The software automatically reads the temperature and humidity data from the host’s thermometer and hygrometer.
⑮	Click OK to go to the warm-up screen, or go to the test screen.

Figure 121

Then wait for the software test to finish. Once the test is complete, refer to Section 8.2 to perform the chromaticity distribution test.

8.2 Chromaticity Distribution Test

After completing the C-Gamma luminous intensity distribution test, a chromaticity distribution test can be conducted based on the test report.

Note: The software must automatically calculate the spatial angle range required for the chromaticity distribution test based on the photometric distribution test report. Therefore, if a photometric distribution test is not performed, a chromaticity distribution test cannot be conducted directly.

Select the photometric distribution test report for this luminaire, then click to open the chromaticity distribution test parameter settings interface.

Figure 122

Number	Note
①	If checked, only the chromaticity characteristics test will be performed; the chromaticity distribution test will not be performed. If unchecked, both the chromaticity characteristics test and the chromaticity distribution test will be performed.
②	Selection of test positions for colorimetric characteristics. The “optical axis” refers to the position directly in front of the light-emitting surface of the sample luminaire; the “point of maximum luminous intensity” refers to the position where the luminous intensity of the sample luminaire is greatest.
③	The angle range for the C-plane is 0 to 360 degrees. There is no need to adjust the angle increment for the C-plane. Symmetrical fixtures, such as indoor lights, can use a larger increment—for example, 30 degrees—while asymmetrical fixtures, such as streetlights, can use a smaller increment—for example, 10 degrees. The smaller the increment, the higher the test accuracy, but the longer the test takes.
④	The gamma plane angle range is automatically calculated by the software based on the results of the photometric distribution test. There is no need to adjust the angle intervals of the gamma plane. You may also select a larger angle interval; symmetrical luminaires, such as indoor lights, can use a larger interval—for example, 10 degrees—while asymmetrical luminaires, such as streetlights, can use a smaller interval—for example, 5 degrees. The smaller the angle interval, the higher the test accuracy; however, the test will take longer.
⑤	Once you’ve finished setting it up, click “Start” to begin the test, and wait for the software to automatically complete the self-test.

①	The angle range for Plane B is automatically calculated by the software based on the results of the photometric distribution test; there is no need to adjust the angle intervals for Plane B. Options include 5 degrees and 10 degrees, for example. The smaller the interval, the higher the test accuracy, but the longer it takes.
②	The beta-plane angle range is automatically calculated by the software based on the results of the photometric distribution test; there is no need to adjust the beta-plane angle intervals, which can be set to values such as 5 degrees or 10 degrees. The smaller the interval, the higher the test accuracy, but the longer the test takes.

Start-up procedure: First, turn on the main power switch for the cabinet. Next, turn on the power switches for the equipment inside the cabinet and in the darkroom one by one. Finally, launch the software. Shutdown procedure: First, close the software. Next, turn off the power switches for the equipment inside the cabinet and in the darkroom one by one. Finally, turn off the main power switch for the cabinet.

Keep the darkroom control room clean and dust-free to prevent dust from entering the equipment. If there is dust on the surface of the equipment, wipe it off with a dry, soft cloth.

Avoid exposing the darkroom to high humidity for extended periods; keep a dehumidifier on hand if necessary.

11.2 Regular Maintenance

11.2.1 Standard Lamp

The standard lamp is valid for one year. If you still need to calibrate the darkroom after one year, we recommend purchasing a new standard lamp.

11.2.2 Software

We update the software from time to time to add features and fix bugs. If you encounter any issues while using the software, please feel free to contact us at any time to obtain the latest version.

11.3 Long-Term Decommissioning and Maintenance

11.3.1 Equipment Cleaning and Protection

Thoroughly clean all equipment surfaces, and cover the main unit, photometric probe, Optical Fibre, and cabinet with dust-proof cloths; disconnect all power sources and unplug power cords and communication cables.

11.3.2 Environmental Protection

Ensure that the darkroom is dry and well-ventilated to prevent equipment from becoming damp. If the ambient humidity is high, keep a dehumidifier on hand.

11.3.3 Monthly Power-On

Conduct a power-on test once a month to ensure that all system hardware is functioning properly.

12. Troubleshooting and Resolving Common Problems

12.1 Communication Errors

Cause of the problem: Check that the communication cable is securely connected and that it is plugged into the correct port; verify that the drivers are installed correctly; try a different USB port or communication cable to rule out hardware issues.

Solution: Reinstall the driver, connect the communication cable according to the device identifier, restart the software, and try again.

12.2 Test Errors

12.2.1 Luminous Flux Anomalies

Cause of the malfunction: Check whether the light source is stable and whether the warm-up time is sufficient; verify that the equipment calibration is valid, that the test distance is correct, and that the standard light is functioning properly; check whether there is any external light interference in the darkroom and whether the light path is obstructed.

Solution: Extend the warm-up time, recalibrate the instrument, turn off other light sources in the darkroom, and remove any obstructions from the light path.

12.2.2 UGR Anomalies

Cause of error: Dimensions of the luminaire’s light-emitting surface were not entered; the luminaire’s beam angle is <45°; the calculation standard was selected incorrectly.

Solution: Enter the dimensions of the luminaire’s light-emitting surface (length/width/height) correctly; verify that the luminaire is an indoor luminaire (the beam angle must be sufficient); select the CIE 190:2010 standard and recalculate.

12.2.3 Abnormal Chromaticity Distribution Test Results

Cause of the malfunction: The test was not conducted based on the photometric distribution test report for the current luminaire; the light intensity was too low, preventing the Spectroradiometer from accurately measuring the colorimetric parameters.

Procedure: Please first conduct a luminous intensity distribution test, and then perform a color distribution test based on that report; if the luminaire’s luminous intensity is too low, please contact us for the best solution.

12.3 The Goniophotomoeter Does Not Rotate

Cause of the malfunction: Check whether the host power is on and whether the wiring is correct; check whether the angle controller inside the cabinet is functioning properly; confirm whether any foreign objects are jammed in the rotating shaft.

Solution: Check the power supply and wiring, and remove any foreign objects; restart the device and software, then try again.

12.4 Software Failures

12.4.1 Software Crashes

Cause of the problem: Check whether you are logged in to the computer’s operating system with an administrator account; verify that the software is fully installed; check whether the database files are corrupted.

Solution: Log in to the computer using an administrator account; reinstall the software and drivers; create a new database file.

12.4.2 The software displays the message “File is not a database”

Cause of the problem: The database file was deleted or moved; the default program used to open LGF files was changed.

Solution: Create a new database file and save it; restore the default program for opening LGF files.

12.5 Power Failure

12.5.1 DC Power Output Abnormalities

Causes of the malfunction: The AC/DC switch on the cabinet was not set to DC; the sample voltage or current exceeded the DC power supply limits; a short circuit in the sample;

Troubleshooting: Please verify that the sample’s voltage and current are within the DC power supply’s output range. For example, the DC3005 model has a maximum output voltage of 30 V and a maximum output current of 5 A. Check whether the sample is short-circuited; if so, repair the sample before retesting.

12.5.2 No AC Output

Cause of the malfunction: The AC/DC switch in the cabinet was not set to the AC side; the overload protection was triggered;

Troubleshooting Steps: Check the AC power output wiring and sample connections to ensure there are no loose connections or short circuits; if the overload protection is triggered, turn off the power, let the unit cool for 5 minutes, and then restart it. Ensure that the sample power remains within the AC power output range; for example, the LSP-500VARC has a maximum output power of 500W.
