机动车灯具生产厂家经常需要在其生产过程当中检测灯具的配光性能 ,所用仪器应当操作方便、测量快捷而精确。根据国家标准的要求和用户需要 ,开发出了一套用于测量机动车前照灯和信号灯的光度和颜色参数的测量系统。介绍了系统的工作原理、方法、特点和测试结果。结果表明 ,该测试系统工作稳定 ,操作简便、测量快捷迅速。同时该系统根据需要配上专用照明附件 ,还可用于测量交通标志等反射物的反射率和反射光的光谱特性 Motor vehicle lighting manufacturers often need to test during the production of lamps with light distribution performance, the instruments used should be easy to operate, the measurement is quick and accurate. According to the requirements of national standards and user needs, a set of measurement systems for measuring the luminosity and color parameters of headlamps and signal lamps for motor vehicles has been developed. The working principle, methods, features and test results of the system are introduced. The results show that the test system is stable, easy to operate and fast to measure. At the same time, the system is equipped with special lighting accessories as required. It can also be used to measure the reflectance and the spectral characteristics of reflected light such as traffic signs
