夜间防范型 LED 照明产品光度学及色度学测试研究

摘要

选用一款型号 ZY4623的夜间防范型 LED 手电筒，对其光谱、光通量、色温、显色指数、色坐标及配光曲线等一系列的光度学与色度学参数及爆闪频率进行测试与分析，为更好的理解和应用防范照明奠定基础。结果表明：夜间防范型手电筒的色温为7624 K，色坐标为（0．2952，0．2996），显色指数达到76．8；爆闪频率为7．6 Hz；配光曲线为狭窄条状，光强分布在光照射方向较小立体角的范围，可实现远距离照亮，比较适于用做夜间防范照明。%In the paper, an Anti-threat lighting LED torch with the type of ZY4623 was investigated for a better understanding and application of Anti -threat lighting products.The blasting flash frequency, colorimetric and photometric parameters, such as light spectrum, luminous flux, colour temperature, colour rendering index, chromaticity coordinate and the light spatial distribution curve , were tested and analyzed. The results show that the color coordinates is (0.2952, 0.2996), the color temperature is 7624K, the color rendering index reaches 76.8; flashing frequency is 7.6 Hz.The light distribution curve is a narrow strip shape, the light intensity distribution in the light irradiation direction with the small solid Angle range which can realize remote light.Therefore it’s suitable for the application of anti -threat lighting at night.
