摘　　要：光效是电光源节能性能的关键参数。本文从实验的角度,通过计算得到白炽灯、节能灯、高压钠灯和金卤灯的光谱能量分布图,并计算得到这四种灯的可见波段能量所占总能量的比例,从而理论上证明了白炽灯光效低,而高压钠灯和金卤灯的光效较高。The luminous efficien is the key parameter of electric light sources energy-saving performance. From the point of view of experiment, This article first calculates the spectrum power distribution of incandescent lamp, fluorescent lamp, high-pressure sodium lamp and the metal-halide lamp, then calculates the ratio of visible spectrum power to the whole spectrum power in order to prove theoretically that incandescent lamps have the low light efficiency, while the high-pressure sodium lamps and the metal-halide lamps have the higher light efficiency.

关 键 词：光效 光谱响应曲线 光谱能量分布
