Energy star's latest standard, IES LM-79-19, was released in 2019. Lisun engineers have published the following article: the difference between lm-79-19 and LM-79-08. For more details, please check here: Interpretation of the latest standards of Energy Star ies lm-79-19.

 

1. Photochromic electric testing system

LPCE-2 high precision spectral radiometer & integration system mainly tests energy-saving lamps, fluorescent lamps, HID lamps (such as high-pressure sodium lamps and high-pressure mercury lamps), cold cathode fluorescent lamps and LED lamps. The test results meet the requirements of CIE and ies lm-79. The lpce-2 system adopts lms-9000b / lms-9500 high-precision rapid spectroradiometer and one-step molding technology to produce a new type of integrating sphere with carrier. The test accuracy of integrating sphere is much higher than that of traditional integrating sphere.
 

Measurement parameters:

Color parameters: chromaticity coordinates, related color temperature, color ratio, peak wavelength, half bandwidth, main peak wavelength, color purity, color rendering index, CQS, tm-30 (RF, RG), spectrogram, etc

Luminosity parameters: luminous flux, luminous efficiency, radiant power, pupil lumen, Si Chen visual lumen, EEI energy efficiency grade, Par and PPF

Electrical parameters: voltage, current, power, power factor

LM-80 LED luminous flux maintenance rate test: luminous flux vs time, color temperature vs time, color rendering index vs time, power vs time, power factor vs time, current vs time and luminous efficiency vs time

2. Distributed Photometer (ies report and distribution curve)

LSG-5000 rotary probe vertical distribution photometer fully meets the requirements of lm-79 article 9.3.1 and en13032-1 article 6.1.1.3 distribution photometer type 4. Lsg-1800b is a dual arm B - β test and a single arm C - γ test. Lsg-1800bccd is a distributed photometer with integrating sphere and goniometer functions. Lsg-1200a is only used for testing lamps with diameter less than 180 mm and luminous angle less than 180 degrees.

3. LED luminous flux maintenance rate and aging life test system

The LED lm-80pl LED luminous flux maintenance rate and aging life test system fully meets the requirements of lm-80, lm-82 and tm-21. We suggest that some factories use sy2036 aging and life test stand with lpce-2 (lms-9000) for alternative testing.
