3 Terms and Definitions

Terms and definitions GB/T 29294-2012 defined in Chapter 3 apply to this document. General requirements Test Method 4 Unless otherwise specified, shall be measured at a relative humidity of not more than 65% and a temperature of 25 ℃ ± 1 ℃ free air convection environment, and should be The LED downlight should be in a stable state. The test voltage should be stable within ± 0.2% range measurement. Luminous flux maintaining rate during the test test voltage stable within ± 2% range. Input current total harmonic content should not exceed 3%. Before measurement, the sample needs to stabilize lit long enough, the time required depends on the type of test sample stability, and stability Time is generally 30min ~ 120min or longer. Once every 15min measuring light output and electric power, when the light output and electricity within 30min Differences three readings of power - when the (maximum and minimum) less than the average of three readings of 0.5% considered stable. Stable sample Time shall be stated in the test report. All tests should be carried out at the rated power frequency, except as otherwise specified for a particular purpose by the manufacturer or responsible vendor. In the luminous flux maintaining rate during the test, in order not to affect the measurement results, avoid sample contamination that may occur during the test (ash Dust, etc.).
