The U.S.A. Energy Star newest standard IES LM-79-19 had issued in 2019 year. LISUN engineer depts already public the Article: How the difference between the LM-79-19 and LM-79-08, the more details please click here. You also can download the LM-79-19 English version standard here.
LISUN supply the Integrating Sphere & Spectroradiometer System, Goniophtometer System and LED Optical Maintenance System to meet the LM-79-19, LM-80, LM-82 and TM-21
Integrating Sphere and Spectroradiometer Test 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 IES LM-79-19, it recommends to using an array spectroradiometer with an integrating sphere to test SSL products.
Measures:
• Colorimetric: Chromaticity coordinates, CCT, Color Ratio, Peak Wavelength, Half Bandwidth, Dominant Wavelength, Color Purity, CRI, CQS, TM-30 (Rf, Rg), Spectrum Test
• Photometric: Luminous Flux, Luminous Efficiency, Radiant Power, EEI, Energy Efficiency Class, Pupil Flux, Pupil Flux Efficiency, Pupil Factor, Cirtopic Flux, PAR and PPF
• Electrical: Voltage, Current, Power, Power Factor (Option: VF, IF, VR, IR), Harmonic (Only LS2010 can test harmonic)
• LED optical maintenance test: Flux VS time, CCT VS time, CRI VS time, Power VS time, Power Factor VS time, Current VS time and Flux Efficiency VS time.
The LSG-5000 is fully meet LM-79-19 request. The LSG-1800B is an B-Beta and C-Gamma goniophotometer. The LSG-1800BCCD is a kind of goniospectroradiometer which has the Integrating sphere and goniophotometer functions. The LSG-1200A is only used to test the lamps which diameter is less than 180mm and beam angle is less than 180degree.
The LEDLM-80PL LED Optical Aging Test Instrument system is fully meet LM-80, LM-82 and TM-21 request. Some of the manufactory we advise to use SY2036 Aging and Life Test Rack with LPCE-2 (LMS-9000) to do an alternative test.
