Whenever entering the interior of Integrating Sphere to perform tasks (such as installing samples or standard lamps), white gloves must be worn; direct contact with the interior coating is prohibited;

Do not use paper towels, rags, or other materials that come into direct contact with the coating to clean it. If dust accumulates, open Integrating Sphere and use a hair dryer Integrating Sphere “cool” setting to blow the dust out from the inside toward the outside (at least once a week);

Be sure to secure the sample firmly during installation to prevent it from falling and damaging the coating; if a small area of the internal coating peels off, contact LISUN to obtain coating repair materials;

If the coating inside Integrating Sphere has peeled off over a large area, or if the coating has darkened significantly due to lack of proper care, please replace Integrating Sphere.

2.3.2 Integrating Integrating Sphere Switching and Handling

Keep Integrating Sphere closed when not in use to prevent dust from entering;

Do not disassemble Integrating Sphere during transport. If disassembly is necessary under special circumstances, be sure to protect the internal coating from contamination;

2.4 Standard Lamp Operating Procedures

The standard lamp has a lifespan of one year and must be replaced when it expires;

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 the standard lamp; if it becomes soiled, clean it before use or replace it with a new one;

Integrating Sphere of different sizes must be used with standard lamps of the corresponding wattage (50W or 100W for large Sphères, and 10W for small Sphères).

2.5 Optical Optical Fiber Operating Procedures

Significant changes in environmental conditions, such as temperature and humidity
The software has added Integrating Sphere and Integrating Sphere	Calibration must be performed separately, and the calibration data for the Integrating Sphere does not affect the calibration data for the Integrating Sphere; each must follow the principles outlined above.

5.2 Calibration Procedure for Integrating Sphere

Take Integrating Sphere large Integrating Sphere as an example. Refer to Section 3.2.1 to connect the two two-conductor cables from the cabinet—a total of four cables—to the large Integrating Sphere junction box.

All of our standard lamps are constant-current DC light sources. Please set the AC/DC switch on the cabinet to DC, as shown in Figure 5-1.

Figure 5-1

Please remove the appropriate standard bulb, put on white gloves, and carefully install it into the E27 socket on the stand. Turn on the crosshair laser to ensure the bulb is centered on the sphere, as shown in Figure 5-2.

Figure 5-2

Then turn off the crosshair laser and Integrating Sphere. If your device has two Integrating Sphere, make Integrating Sphere both are turned off (Optical Fiber reads signals from Integrating Sphere simultaneously).

Switch the software to “Large Integrating Sphere,” then click “Spectral Calibration,” as shown in Figure 5-3.

Figure 5-3

If your software is already communicating properly with the LISUN DC power supply, please refer to Section 5.2.1 to continue; if your software is not communicating with the LISUN DC power supply, please refer to Section 5.2.2 to continue.

5.2.1 The software is communicating properly with the LISUN DC power supply

If you have purchased a LISUN DC power supply and have successfully established communication with it in “System Configuration,” please follow the instructions in the table and diagram below, as shown in Figure 5-4.

Number	Note
①	The device automatically displays the DC power supply model and communication port, eliminating the need to select or search for the port again.
②	To make the process more convenient, please check the “Auto-On” and “Auto-Off” options.

④	Click to control the DC power supply output and verify that the test lamp illuminates properly. When the test lamp is lit normally, the DC power supply should display “CC” (constant current output), and the displayed current value should match the input value exactly; the displayed voltage will fluctuate around 25V. If the displayed current does not match the entered value (fluctuations in the last digit after the decimal point are normal) or if the displayed voltage differs significantly (for example, only around 10 V), the standard lamp is not lighting up properly. Please check the standard lamp’s filament, its installation, and all wiring, then try again.
⑤	The color temperature and luminous flux are listed on the standard lamp certificate and the standard lamp packaging. Please enter them correctly. Note: The specifications vary by lamp; please do not mix them.
⑥	For points accumulation, be sure to check the “Auto” box.
⑦	Average count; the default is 10; no changes are needed.
⑧	The warm-up time is set to 15 minutes by default; no changes are necessary. In other words, after clicking “Start,” the software will wait 15 minutes for the standard lamp to warm up, and once the data has stabilized, it will automatically perform calibration.
⑨	Once you have confirmed that the above settings are correct, click “Start.” The software will automatically perform the following steps in this order: automatically control the DC power supply to turn on the standard lamp; start the warm-up countdown; automatically perform calibration when the warm-up countdown ends; and, after successful calibration, automatically control the DC power supply to turn off the standard lamp.
Note	In the calibration interface, do not perform any actions on the sections not listed in this table!

Figure 5-4

After successful calibration, the following interface will appear, as shown in Figure 5-5.

③	For points accumulation, be sure to check the “Auto” box.
④	Average count; the default is 10; no modification is necessary.
⑤	The warm-up time is set to 15 minutes by default and does not need to be changed. In other words, after you click “Start,” the software will wait 15 minutes for the standard lamp to warm up, and once its data has stabilized, it will automatically perform calibration.
⑥	Once you have confirmed that the above operations and settings are correct, manually operate your DC power supply. Refer to the corresponding current value listed on the standard lamp certificate and the standard lamp packaging to ensure constant-current output and turn on the standard lamp. When the standard lamp is lit normally, the DC power supply should display “CC,” indicating constant current output, and the displayed current value should match the entered value exactly. The displayed voltage will fluctuate around 25V. If the displayed current does not match the entered value (fluctuations in the last digit after the decimal point are normal) or the displayed voltage differs significantly (e.g., only around 10V), the standard lamp is not lit properly. Please check the standard lamp’s filament, installation, and all wiring, then try again. Once the standard lamp is lit normally, click “Start.” The software will automatically enter the warm-up countdown. When the warm-up countdown ends, calibration will begin automatically. After calibration is successful, please manually turn off the standard lamp using the DC power supply.
Note	In the calibration interface, do not perform any actions on the sections not listed in this table!

Figures 5–6

After successful calibration, the following interface will appear, as shown in Figure 5-7.

5.3 Procedure for Calibrating Integrating Sphere Small Integrating Sphere

Refer to Section 3.2.1 to connect the two two-conductor cables from the cabinet—a total of four cables—to the small Integrating Sphere junction box.

Set the software to “Small Integrating Sphere.”

Install the standard bulb. Note: Integrating Sphere 0.3-meter Integrating Sphere does not include an E27 socket. Please wear white gloves and carefully remove the 10W standard bulb so that it can be installed in the 0.3-meter Integrating Sphere Sphere. The 0.5-meter small Integrating Sphere Sphere includes an E27 socket; there is no need to remove the bulb.

Remove the 10W standard light bulb, as shown in Figure 5-8:

Figure 5-8

All other operations are exactly the same as those for Integrating Sphere; please refer to Section 5.2.

6. Testing

6.1 Integrating Sphere Test

6.1.1 Calibration Verification

Refer to Section 5.1 to determine whether recalibration is necessary.

6.1.2 Sample Installation

When the stage is mounted at the bottom, the sample’s light-emitting surface should face upward; when the stage is mounted at the top, the light-emitting surface should face downward—it must not face to the side. Use the crosshairs as a reference to adjust the sample’s position so that its light-emitting surface is exactly in the center of Integrating Sphere. Secure it firmly with screws or clamps to prevent it from falling during testing.

If the sample is an E27 light bulb, it can be mounted directly onto the stage or mounted onto the stage using an E27 adapter; no power cord is required. See Figure 6-1.

Figure 6-1

If the sample is a linear light fixture, a linear light fixture clamp may be installed and used, as shown in Figure 6-2.

Figure 6-2

For other samples, place them directly on the stage or secure them with screws; the stage is equipped with M6 screw holes. Ensure that they do not fall off; see Figure 6-3.

Figure 6-3

Connect the power cord to the two POWER terminals on the stage; the two SENSE terminals do not need to be connected. If using a DC-powered lamp, be sure to connect the positive and negative terminals correctly.

After installation, turn off the crosshair laser and Integrating Sphere. If your device includes two Integrating Sphere, make Integrating Sphere are turned off at the same time.

6.1.3 Cabinet Power Switching

If the sample is powered by DC, set the AC/DC switch on the cabinet to the DC position; if the sample is powered by AC, set the AC/DC switch on the cabinet to the AC position.

6.1.4 Verification of the Self-Absorption Coefficient

Integrating Sphere testing relies on diffuse reflection from the Sphere’s walls to take measurements. Therefore, if the sample is a relatively large luminaire, “self-absorption” may occur—that is, some of the diffuse reflected light is absorbed by the luminaire itself—which can cause deviations in the test results. Bare light sources and small luminaires can be tested directly; for larger luminaires, an Auxiliary Lamp must be used for correction, as shown in Figure 6-4.

Number	Note
①	Click “Self-Absorption Coefficient”
②	For bare light sources or small luminaires, select “Do not use an auxiliary light for correction,” which corresponds to a correction factor of 1. For larger luminaires, select the appropriate correction factor from the drop-down list. If no correction factor has been generated for this sample previously, you will need to use an auxiliary light to generate a new correction factor; please refer to Chapter 8.
③	After selecting the correct auxiliary light correction factor, click “OK” to exit this page.

Figure 6-4

Note: Even if the software or computer is shut down, the software will still use the last self-absorption coefficient by default the next time it is opened. Therefore, you must verify that you are using the correct self-absorption coefficient before each test.

6.1.7 Preheating Parameter Settings

See Figures 6–8.

Number	Note
①	Click “Preheating Parameter Settings”
②	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 color parameters stabilize, after which the test will proceed automatically.
③	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.
④	If checked, the test will automatically skip the remaining warm-up time and begin once the light fixture has stabilized; if unchecked, the test will begin only after the warm-up period has elapsed as set.
⑤	If checked, test reports for all sampling points will be saved automatically; if unchecked, only the final test report will be saved automatically.
⑥	Definition of a luminaire’s steady state. If 20 and 0.5% are set, the luminaire is considered to be in a steady state if the parameter has not varied by more than 0.5% over the past 20 minutes.
⑦	You can select which parameters the software should use to determine whether a light fixture is stable: optical parameters, electrical parameters
⑧	The software will save the change curves for the selected parameters during the warm-up period to the test report.

6.1.8 Verify the test control parameters and conduct the test

See Figures 6–9.

Number	Note
①	If the “Auto Turn On” and “Auto Turn Off” options are checked, clicking “Test” will cause the software to automatically turn on the light fixture according to the entered electrical parameters. Once the test is complete, the software will automatically turn off the light. Note: If you check the “Auto Turn On” option, you must also check “Preheat.” If you do not enable preheating—that is, if the software turns on the fixture and immediately begins testing—the interval between these actions will be too short, and the test results will not be reliable.
②	If the “Auto On” and “Auto Off” options are not checked, you can also turn the light on or off by tapping this button.
③	Be sure to select “Automatic” for “Points Time”; otherwise, the test results will be inaccurate.
④	If you need to preheat, check the box; if not, leave it unchecked.
⑤	Click to run the test. If “Warm-up” is checked, the software will enter a warm-up countdown and display the current warm-up progress and data in the upper-right corner; if “Warm-up” is not checked, the software will run the test immediately and display the test results.

8. Generation of the Self-Absorption Coefficient (Use of an Auxiliary Light)

8.1 Scenarios for Using Auxiliary Lights

For larger luminaires, the issue of self-absorption may arise. If a correction factor for the auxiliary light has not been generated previously, you must first generate the correction factor using the auxiliary light before conducting the test. Self-absorption is related to the luminaire’s housing dimensions, shape, color, and other factors; therefore, the self-absorption coefficient varies for different luminaires.

Note: The darker the color of the luminaire and the larger its size, the more severe the “self-absorption” issue becomes. Users can gain practical experience regarding whether to apply an auxiliary light correction factor. For example, for certain small luminaires, if the correction factor obtained after applying the auxiliary light correction factor is 1.02, this indicates that the luminous flux test result will increase by 2% after applying the correction factor; For example, for certain large luminaires, if the correction factor obtained after applying the auxiliary light correction is 1.13, this indicates that the luminous flux test result will increase by 13% after applying the correction factor.

8.2 Installation and Wiring of Auxiliary Lights

① Remove the plug from the opposite side of Integrating Sphere large Integrating Sphere to prepare for installing the auxiliary light fixture; see Figure 8-1.

Figure 8-1

Locate the auxiliary light fixture, as shown in Figure 8-2:

Figure 8-2

Remove the screws and washers, as shown in Figure 8-3:

Figure 8-3

Feed the auxiliary light fixture out from the inside of Integrating Sphere, as shown in Figure 8-4:

Figure 8-4

For auxiliary light wiring, see Figure 8-5.

Number	Note
①	Then secure the screws and washers to the outside of Integrating Sphere
②	Please connect an extension cord with a banana plug to the side of the cabinet and keep it on hand. Note: We do not provide the wire connecting the auxiliary light to the DC power supply; we only provide the banana plug. Please find a wire of the appropriate length and make the connection yourself.

Figure 8-5

Adjust the length of the wire to ensure that Integrating Sphere can be properly connected to the front panel of the DC power supply, whether it is closed or open, as shown in Figure 8-6.

Figure 8-6

Please wear gloves, remove the auxiliary light bulb, and install it in the auxiliary light fixture, as shown in Figure 8-7.

Figure 8-7

8.3 Steps for Generating the Self-Absorption Coefficient

Connect the auxiliary light power cord to the output terminal on the front panel of the DC power supply, as shown in Figure 8-8.

Figure 8-8

Go to the self-absorption coefficient interface, as shown in Figures 8 and 9.

Number	Note
①	Click “Self-Absorption Coefficient”
②	Click “Add”

Figures 8–9

Generated from the absorption coefficient, Step 1; see Figures 8–10.

Number	Note
①	Enter the model number of the luminaire under test. If you test the same luminaire again later, you only need to select the corresponding correction factor from the list of self-absorption coefficients; there is no need to generate the correction factor again.
②	A: If the DC power supply has successfully established communication in “System Configuration,” the correct DC power supply model and port number will automatically be displayed here; you can also click “Search” to rescan for the correct port . B: If you have not purchased a LISUN DC power supply or communication has not been established, please select “Not Installed” for the DC power supply model; otherwise, the software will display an error.
③	A: If the software has successfully communicated with the DC power supply, the auxiliary lamp data can be found on the packaging and the calibration certificate; enter the rated current and reference voltage . B: If the software has not successfully communicated with the DC power supply, there is no need to enter the current, voltage, or warm-up time ; generally, a 15-minute warm-up is sufficient.
④	Follow the instructions here for Steps 1 and 2. At this point, both the standard lamp and the auxiliary lamp are inside Integrating Sphere. The standard lamp must be installed exactly at the center of Integrating Sphere, but do not connect its power cord (it is used only to simulate the calibration environment). Then, turn off Integrating Sphere. If your device includes Integrating Sphere, turn Integrating Sphere off at the same time.
⑤	A: If the software has successfully established communication with the DC power supply, you can simply click “Start.”and the software will automatically control the DC power supply to illuminate the auxiliary light at a constant current, then enter the warm-up countdown . B: If the software fails to establish communication with the DC power supply, you must first manually control your DC power supply to illuminate the auxiliary light at a constant current, then click “Start” to enter the warm-up countdown.

Figures 8–10

Generated from Step 2 of the absorption coefficient calculation; see Figures 8–11.

Number	Note
①	After the 15-minute warm-up period, the software proceeds to Step 2 of 2. Following the instructions here, open Integrating Sphere, remove the standard lamp, and place the lamp under test in the center of Integrating Sphere—but do not connect the power cord to the lamp under test (this is only for simulating the test environment). At this point, the auxiliary lamp remains on. Then close Integrating Sphere.
②	Click “Finish.” The software will automatically calculate the self-absorption coefficient.

Figures 8–11

Autocorrelation coefficient generation; see Figures 8–12.

Number	Note
①	Self-absorption coefficient calculated automatically by the software
②	Click “OK” to automatically save and exit the self-absorption coefficient generation interface. A: If the software has successfully communicated with the DC power supply, you can turn off the auxiliary light through the software. B: If the software has not successfully communicated with the DC power supply, you can manually turn off the DC power supply output.

Figures 8–12

After using the auxiliary light, be sure to disconnect its power cord. If the auxiliary light will not be used for an extended period, allow it to cool down, then remove it and store it properly.

8.4 Testing Using the Auxiliary Light Correction Factor

During testing, the auxiliary light correction factor just generated will be used by default. Please refer to Chapter 6 for testing instructions.

Note: The auxiliary lights are used solely to generate correction factors; please do not turn them on during official testing.

10. Troubleshooting and Resolving Common Problems

10.1 Hardware Communication Failures

Causes of the problem: Driver not installed or installation failed; incorrect USB port connection; incorrect device model selected;

Troubleshooting Steps: Check the computer’s Device Manager to verify that the LMS-9000 and the four COM ports are functioning properly (no exclamation marks);

Reinstall the drivers (with antivirus software disabled) to ensure that both the communication box driver and the spectrometer driver are successfully installed; connect the USB cable directly to a native USB 2.0 or 3.0 port on your computer (do not use a USB hub or USB extension cable); go to “System Configuration” in the software, reselect the device model, and click “Search for Port.”

10.2 Calibration Errors

10.2.1 The standard lamp won’t turn on

Causes of malfunction: The AC/DC switch is not set to the DC position; “Auto-Light” is not checked on the calibration screen; incorrect voltage or current parameters; broken filament;

Troubleshooting Steps: Ensure the AC/DC switch on the cabinet is set to “DC” and that the standard lamp is securely connected; verify that “Auto Illumination” is checked on the calibration interface, and that the entered voltage and current match those specified in the standard lamp certificate; inspect the standard lamp filament—if it is broken or blackened, replace the standard lamp.

10.2.2 Calibration Prompt: “Signal Too Weak”

Causes of malfunction: Optical Fiber connected; Integrating Sphere lid not closed properly; standard lamp not lit; Optical Fiber kinked or broken;

Troubleshooting: Check that Optical Fiber is securely connected at both ends and is not excessively bent; close Integrating Sphere to ensure it is properly sealed and no external light is entering; verify that the standard lamp is lit; if it is not, follow the troubleshooting steps in Section 5.2; if Optical Fiber is broken, contact us for a replacement.

10.3 Test Data Anomalies

10.3.1 Inaccurate Test Data

Causes of malfunction: Failure to perform regular calibration, incorrect correction factor for the auxiliary lamp, improper selection of Integrating Sphere, damaged coating, or issues with the sample itself

Procedure: Recalibrate according to Chapter 5, ensuring the calibration interval is ≤ 1 week; set the correction factor to 1 for bare light sources and small luminaires, and use the correct correction factor for large luminaires; Use Integrating Sphere for large samples and a small Integrating Sphere for small samples to avoid size mismatches; if the Integrating Sphere Sphere’s coating is severely peeling or has significantly darkened, contact us for repair; test several additional sets of different sample types; if most results are acceptable, the issue lies with the sample itself.

10.3.2 Excessive Variation in Test Results

Cause of the malfunction: Insufficient preheating time; severe sample flicker;

Solution: Extend the warm-up time (e.g., 20–30 minutes) and wait for the sample to stabilize before testing; use a flicker tester to check the sample for flicker issues.

10.3.3 Electrical parameters are displayed as 0

Cause of the malfunction: Incorrect selection of the power meter model; incorrect wiring;

Troubleshooting Steps: Go to “System Configuration” in the software, select the correct power meter model, and rescan the ports; check the power meter wiring to ensure that A1, A2, V1, and V2 are connected correctly and securely.

10.4 Software Operation Errors

10.4.1 The software won’t start (no response when double-clicked)

Cause of the problem: Not running as an administrator; incomplete software installation;

Solution: Right-click the software shortcut and select “Run as administrator”; uninstall the old software, delete any remaining folders, and then reinstall the software.

10.4.2 Software Fails to Open or Database File Error

Causes of the problem: Insufficient software permissions, the save path does not exist, or the file is in use;

Solution: Run the software as an administrator; create a new database file; do not save the database file directly to your desktop.

10.5 Power Failure

10.5.1 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.

10.5.2 No AC Output

Cause of the malfunction: The AC/DC switch on the cabinet was not set to the AC side, and 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.
