投影机能效标准制定的技术预研

Technic Pre-research about Energy Efficiency Standard for Projectors

投影机根据工作原理、光源和光输出量的区别,有不同的分类方式。投影机能效标准在能源效率测试方法上不需要考虑投影机的分类,统一测试方法为白场信号下产品光输出和功耗的比值。待机测试采用功率积分的方式进行测试。根据光输出的差异,统计近期投影机节能测试的结果,提出不同的能效指数限定值要求、待机功耗要求。

Projectors has some kinds of sorts,according as the different between working elements,lamp house and luminance output. The measure method of the energy efficiency prescind from the sorts, uses luminance output divide on mode power to measure energy efficiency, uses integrate to measure passive standby power. But the minimum allowable values of energy efficiency consider the difference of luminance output.
