| 摘 要： | 介绍两种光源光通量测量方法：加V（λ）修正的光度计法和分光法,比较各自的特点,并分析影响光通量测量结果的因素。加V（λ）修正的光度计法测量光通量简捷、快速,但无法同时测量光色参数。随着新型光电测试技术的日益成熟,光谱辐射计性能越发完善,除了测量光源光通量,还可计算光源的色品坐标、色温、显色指数、色容差等色度参数。在CIE127中分光法被推荐为测量光源光色参数的方法。

| Abstract: | The comparison between "Measuring light sources luminous flux by photometer with V(λ) modification","Measuring light sources luminous flux by spectral radiometer" is given . The difference of two methods is discussed. The photometric method with V(λ) modification is simple and rapid,but the color parameters can not be measured . With the devolopement of photoelectric testing technology, the performance of spectral radiometer is improved. Not only the luminous flux but also the color parameters such as chromaticity coordinates, color temperature, color rendering index, color tolerance can be measured by spectral radiometer method, which is recommended to be the method of measuring the luminous flux and the color parameters, in CIE127 《Measurement of LEDs》. |
