All of you who are engaged in lighting products, whether as light sources or lamps, must have heard of test projects such as LM79, LM80, LM82, LM84 and TM21. These test reports need to be used when we apply for many energy efficiency certification projects. Today, I will briefly introduce the basic contents of these projects.
1กข LM79
LM79 defines the test methods for the total luminous flux, electric power, light intensity distribution, color parameters, color uniformity and other parameters of SSL products. This standard covers SSL products for LEDs and integral LED lamps (required to be driven by AC or DC only). This standard does not cover SSL products (LED chips, LED packages, LED modules, etc.) that require external drive circuits or external heat sinks. SSL is different from the traditional filament white flag light emission and gas discharge light emission principle. It is electroluminescent from semiconductor, including LED, OLED, Laser Diode (LD), light emitting polymers Generally speaking, the test can be divided into integrating sphere test and distribution photometer test: integrating sphere test: voltage, current, power, color temperature, color rendering index, spectral distribution Distribution photometer test: voltage, current, power, total luminous flux, light intensity distribution, color uniformity For LM79, the integrating sphere test does not measure luminous flux, otherwise it requires complicated steps such as auxiliary lamps.
2กข LM80
LM80 refers to the measurement of light source, and "light source" only refers to package, array and module. The key points are as follows: a. The aging process is separated from the testing process, and the temperature of Tc point shall be strictly controlled as 55 กใ C, 85 กใ C or the temperature of supplier * * *. After aging to the specified test interval, restore to the test environment for photometric test. b. It is required to test luminous flux and color parameters, and the specific test methods are not strictly specified. The following is the or |
