摘　　要：为了更好地了解LED照明产品的测量差异,寻找存在差异的原因,提高实验室之间测量结果的一致性,中国、德国两个国家的六个实验室对两组商用LED照明产品,包括LED球泡灯、LED筒灯、LED路灯进行了测量比对。两个国家的不同实验室采用了不同的测试设备,并分别溯源至本国的计量标准,比对结果表明各实验室间光通量的差异在±5%内,色温的偏差为±250 K内,虽大于中德两国光通量和色温单位量值之间的偏差,但仍然可以满足产品生产过程中的质量控制及国际贸易的需求。这表明只要测量设备按期校准、测试样品的测试条件尽量接近,不同实验室测试结果之间的偏差可以控制在可接受的范围之内。To investigate the measurement deviation of LED lamps and luminaires between China and Germany and improve the common LED lighting measurement standard and test procedure, we have promoted comparison measurements for LED lighting products among six laboratories. The most commercially used retrofit lamps, downlights and streetlights were measured and compared. Although using different test instruments from different manufacturers, different methodology and calibration routine, traced to the national standard of their own country, the results show that the test deviation for luminous flux is about ±5 % and the CCT deviation is less than ±250 K. The results suggest that as long as the measurement equipment is calibrated regularly and with the similar burn-in and testing procedures, the test deviation is within the acceptable range for quality control of manufacturing process and the international trade.
