《GB/T 19658-2005反射灯中心光强和光束角的测量方法》由TC224(全国照明电器标准化技术委员会)归口,TC224SC1(全国照明电器标准化技术委员会电光源及其附件分会)执行,主管部门为中国轻工业联合会
本标准规定了反射灯的中心光强和相应光束角的定义和测定方法。本标准适用于普通照明用白炽灯、卤钨灯以及支体放电灯类等反射灯,但不适用于特殊用途的灯,例如投光灯。本标准仅涉及灯的设计试验。


Scope

This standard specifies the definition and measurement method of the central light intensity and the corresponding beam angle of reflector lamps. This standard applies to reflector lamps such as incandescent lamps, tungsten halogen lamps and gas discharge lamps for general lighting, but not for lamps for special purposes, such as floodlights. This standard only deals with design tests of lamps.
