摘要
本文阐述了目前使用高压钠灯为光源的道路灯具出现“高”灯具效率的原因,指出这种高灯具效率是以牺牲光源寿命为代价的。文中给出了一种真正衡量灯具效率的方法,并指出按目前测试方法得到的比值应该称为灯具光输出比。
The paper expatiates on the reason of HPS road lighting fixture with a ＂high＂ luminaire efficiency, and indicates this ＂high＂ luminaire efficiency is obtained at the cost of lamp life. Then it introduces a new method to test luminaire efficiency, and point out it should be called luminaire light output ratio according to the present test method.
