Lisun Instruments Limited products

LSG-6000 Moving Detector Goniophotometer (Mirror Type C) was manufactured by LISUN completely meets LM-79-19, IES LM-80-08, COMMISSION DELEGATED REGULATION (EU) 2019/2015, CIE-121, CIE S025, SASO 2902, IS16106 and EN13032-1 clause 6.1.1.3 type 4 requirements. LSG-6000 is the latest upgraded product of LSG-5000 and LSG-3000 in compliance with the requirements of the LM-79-19 standard Clause 7.3.1, its an automatic light distribution intensity 3D curve testing system for measuring light. The darkroom can be designed according to the customer’s existing room size.

LSG-1890B/LSG-1800A goniophotometer is automatic goniophotometric instrument for luminous intensity distribution measurements with facility for rotating the light source. The LSG-1890B/LSG-1800A uses a constant temperature detector, Japanese motor and German precision angle coder which keep the test results with high accuracy. It is used for industrial laboratory photometric data measurement of all kinds of luminaries such as LED luminaries, HID lamps, fluorescent lamps and so on.

LSG-2000 Goniophotometer with Rotating Mirror is also called the Moving Mirror Goniophotometer. The LSG-2000 is an automatic light distribution intensity 3D curve testing system. The darkroom can be designed according to the customer’s existing room size. It can measure all types of lighting sources, LED or HID luminaires such as indoor and outdoor luminaires, roadway luminaires, street lamps, flood lights and other kinds of luminaires.

LMS-9500 Scientific Grade High Accuracy CCD Array Color Spectroradiometer fully meets Energy Star IESNA LM-79, GB/T24824 and  other related standards. It can test CFL, HID, Promise Light, Tungsten Halogen Lamps, which can reach the scientific grade measurement accuracy. LMS-9500 is composed of Concave Average Diffraction Grating and Scientific Grade CCD, and it uses unique stray light control technology, wide dynamic linear technology, precision CCD electronic drive technology and complex matrix software technology. The instrument is traceable to the Chinese National Institute of Metrology(NIM) and the USA NIST standards.

LMS-9000C High Precision CCD Spectroradiometer/spectroradiometry is according to LM-79 clause 9.1. It is designed for any visible optical spectrum distribution analysis, mimicking various light sources in the visible region by feedback control of the radiant power emitted by individual LEDs. This LED optical spectrum analyzer will be used as a transfer standard for photometric, colorimetric and radiometric applications. LMS-9000C can do quick test with high accuracy. It used in scientific lab. It works with integrating sphere and standard lamp as a system: LPCE-2 High Precision Spectroradiometer Integrating Sphere System. 

LMS-7000 spectroradiometer applied with Japanese high-precision CCD detector, which has excellent speed, high stability and high accuracy.

Integrating sphere is widely applied in testing lumen, chromaticity coordinates, CCT, dominant wavelength and peak wavelength etc for light source or luminaries. The IS-M is the tradiontal Integrating sphere, LISUN already stop producing it but instead with A molding technology integrating spheres IS-MA

IES LM-79 Clause 9.1.2 requests the 4π geometry and 2π geometry configuration integrating sphere for the LED testing. LISUN developed the photometric integrating sphere with side assistant opening using a-molding technology to meet the requirements. The IS-*MA**C/IS-*MA**P integrating sphere has all of the specification of IS-*MA.

Due to the LED street luminaries developed, it is hard to do 4π geometry test in the traditional integrating sphere. Because there is no test base (platform) to hold so heavy LED outdoor lighting fixtures. LISUN IS-*MA Optical 4π Geometry Integrating Sphere With Holder Base is designed for this kind of LED luminaires.

LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84,  CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, COMMISSION DELEGATED REGULATION (EU) 2019/2015, IESNA LM-63-2, IES-LM-80 and ANSI-C78.377, it recommends to using an array spectroradiometer with an integrating sphere to test SSL products. The LPCE-2 system is applied with LMS-9000C High Precision CCD Spectroradiometer or LMS-9500C Scientific Grade CCD Spectroradiometer, and a-molding integrating sphere with holder base. This sphere is more round and the test result is more accruate than the traditional integrating sphere.
