LM-79 and LM-80 Test Solutions

For the LED manufactory to pass LM-79 and LM-80 test is more and more important. Lisun can supply the full solution for LM-79 and LM-80 test system. Please feel free to contact with Lisun Sales Dept for the detail technical solution and formal quotation at: [email protected]

1. Photo, Color and Electricity Test System

• Integrating Sphere Spectroradiometer System for LED
LPCE-3(LMS-7000) is according to LM-79 and LM-80, and it is a high accuracy test system which is similar as US and Germany level. The system can test the color parameters such as CCT, CRI, Spectrum, Flux, Flux Efficient, Power, Power Factor, Voltage, Current and so on.

 

• Integrating Sphere Spectroradiometer System for LED
LPCE-2(LMS-9000) is accepted by many LED luminaire manufactory. It meets LM-79 and LM-80. The system can test the color parameters such as CCT, CRI, Spectrum, Flux, Flux Efficient, PAR, EEI, PPF, TM30, Power, Power Factor, Voltage, Current and so on.

 

2. Goniophotometer System

The Goniophotometer is used to test the intensity distribution curve in 3D and export IES or LDT file for the lighting software such as DiaLux. The Goniophotometric System is according to LM-79, LM-80, IEC and CIE Standards. According to LM-79 clause 9.3.1, you need to use LSG-5000 moving detector goniophotometer.

3. LED Lumen Maintenance and Aging Life Test System

The LEDLM-80PL system is designed according to standards IES LM-80, LM-82, TM-21, etc. Different from traditional light source, LED will decay gradually rather than extinguish instantly. So according to LM-80, we test L70(hour): time to 70% lumen maitenance and L50(hour): time to 50% lumen mentainance.
