1概况长期以来,对照明灯具的检测只限于安全方面,对于性能,尤其是灯具效率,提及很少。一些发达国家或地区虽然提出在灯具销售时必须附上光强分布曲线,但对其量值并未加任何限制。由于没有相关标准的制约,灯具的效率低下。在当前地球资源短缺和温室效应日趋严重的情况下,世界各?
1 Overview For a long time, the detection of lighting fixtures only for safety, for performance, especially the efficiency of the lamp, mentioned very little. Although some developed countries or regions in the lighting sales must be attached to the light intensity distribution curve, but its value without any restrictions. Due to the lack of relevant standards, lighting is inefficient. In the current global shortage of resources and the growing greenhouse effect, the world?
