1前言我国光源颜色温度（简称色温）基准是采用铂凝固点黑体，而其副基准则是采用了两种型号的稳定性优良的白炽钨丝标准灯组。一组为BZ5型灯，用于2042—2353K范围；另一组为BZ6型灯，用于2353—2856K范围。因基准点色温值为2042K，对于高于2042K的量值范围，则是用光谱辐射测
1 Preface China’s light source color temperature (referred to as color temperature) benchmark is the use of platinum solidifying point blackbody, and its vice benchmarks is the use of two models of excellent stability incandescent tungsten standard lamp group. One for the BZ5 lamp for the 2042-2353K range; the other for the BZ6 lamp for the 2353-2856K range. Due to the reference point color temperature value of 2042K, for the value range above 2042K, it is measured with spectral radiation
