LSG-2000 is an automatic light distribution intensity curve in 3D Goniphotometer testing system, the test distance is from 5m to 30m. It can measure all type of lighting sources, LED or HID luminaires such as indoor and outdoor luminaires, roadway luminaires, street lamp, flood lights and other kinds of luminaires

Measures:
Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaries Efficiency, Luminance Distribution, Coefficient Of Utilization, Luminance Limitation Curves Glare, Maximum Ratio Of Distance To Height, Equal Illuminance Diagrams, Curves Of Luminaires Vs Lighting Area, Lsocandela Diagrams, Efficient Luminescence Angle Etc.

Features:
•Many national patents pending on hardware and software
•CIE Class A & Constant temperature photo detector (Class L detector can be optional)
•High degree of intelligent and test function is complete
•The rotation motor is from Japan MITSUBISHI MOTORS and use Germany Angle decode system, it will help rotation smoothly and high accuracy, it is very stable when start and stop
•The work principle is according to IESNA and CIE, it is special recommend by LM-75, LM-79 and CIE121-1996
•With some optional instruments, it has good expanding functions
•The position and working state remain the same as it is under working.
•Special collimation device with laser cross line, convenient and accurately fix the position of the tested luminaries.

Specifications:
•The tested luminaire rotates around the mirror with an angle of (γ)±180°(or 0-360°) and the tested luminaire rotates around itself with an angle of (C)±180°(or 0-360°).
•The accuracy of angle: 0.1° Resolution of angle: 0.01°
•Accuracy of photometry: CIE class A (Standard Class) or can be optional Class L.
•The test result can be export CIE, IES, LDT and other format files. This kind format files can be transferred by other illumination and luminaire design software such as DiaLux.
• RS-232C standard interface connect with PC, English version software can be run in WinXP or Win7
 

LSG-2000 can be added a USB CCD Spectroradiometer to test spatial CCT Distribution and other Spectral colori parameters. We called this system as Goniospectroradiometer (LSG-2000CCD). Please refer to this documents: A Near-field Goniospectroradiometer for LED Measurements

Products of this category:
LSG-2000: Mirror on optical axis. When measuring light source, the holder for light source has to move in a large space during the measurement.
LSG-1900: Lamp on optical axis. It overcomes the problem of instability of the tested light source when measuring light intensity.
LSG-1800: With facility of double arms for turning the light source. When doing light measurement, the long measuring distance can easily be achieved.
LSG-1600: With facility of single arm for turning the light source when doing the measurement of light.
LSG-1200: The compact one is the best way for light intensity measurement of small or weak sources.
LSG-880: This goniophotometer is the best answer of how to measure light of LED cup lamp or spotlight.
