Light sources for improving visual perceptions under mesopic lighting conditions |
摘要 |
A light source such as a ceramic metal halide lamp has a spectral distribution of emitted light which at a first operating power substantially corresponds with the sensitivity of the human eye under photopic conditions. When the lamp is operated at an operating power less than the first operating power, the spectral distribution of emitted light shifts to substantially correspond with the sensitivity of the human eye under mesopic or scotopic conditions. |
