一、前言目前国内市售照度计的量程一般都在0～15万勒克司左右。在0～3000勒克司范围内,是按照“照度计检定规程”来检定的;而对于3000勒克司以上高照度值的检定,现在还没有国家标准可循,是目前照度计和光电器件检定中的一大难题。为此,我们根据D.Prokic提出的使用二个光源来获得高照度,对大量程照度计进行检定的方法,研制成了一套较为系统的标准光度叠加装置,在国内首次实现了3000～15万勒克司A光源(2856°K)的标准光
First, the preface At present, the domestic market range of illumination meter are generally 0 to 150,000 lux. In 0 ~ 3000 lux range, is in accordance with the “test procedures for illumination meter” to test; and for 3000 lux above the high illumination value of the test, there is no national standard to follow, is the current illumination meter and photoelectric device test A big problem To this end, we have developed a set of more systematic standard photometric superposition device according to D.Prokic’s method of using two light sources to obtain high illuminance and large-scale illuminance meter, and achieved the first time in China for 3000 ~ 15 Standard light from a 10,000 Lux A source (2856 ° K)
