Zhang Hong: The first round of China LED product testing and evaluation report
Zhang Hong, Senior Manager of Electrical Appliances of CTI China Testing Technology Co., Ltd. introduced the China LED Evaluating and Assessment Reporting (CLEAR), the first round of CLEAR testing began in April 2010 and continued through 2010. The test ended in June. The samples tested were all voluntarily delivered by the manufacturer. The samples included 3 types (LED bulb, PAR lamp and MR16 lamp), a total of 15 samples, tested by Labsphere integrating sphere-spectrum radiometer test system, the main test items The measured input power, initial total luminous flux, luminous efficiency, correlated color temperature CCT, color rendering index CRI.
According to the test results, the luminous efficacy is in the range of 25.58-84.38 lm / W, the average luminous efficiency is 57.05 lm / W, the average level of light efficiency has met the current energy star standard for the minimum luminous efficacy of the integrated LED lamp Requirements; The standard requirements for CCT are only allowed to have 4 nominal CCTs, which are 2700K, 3000K, 3500K and 4000K respectively; the requirements for CRI (Ra) must be not less than 80. In this round of test results, none of the samples meet the requirements of both CCT and CRI. Only 6 samples alone meet the CCT requirements, accounting for 40% of the total; only 2 samples alone meet the CRI requirements, accounting for 13.3% of the total; in this round of 15 LED lamp samples, LED bulbs The level of light efficiency is significantly better than LED directional lights. At the same time, in this round of test results, there are many high-efficiency LED lamp samples, and their color characteristics are not satisfactory.
