In this paper, by studied the selective that crops absorb light wave in photosynthesis- photomorphogenesis reaction and photoperiod adjustment, analyzed those light sources which be used in greenhouse to light crops, we discovered that those light sources?spectrum are not matching with the crops?absorbing spectrum, so the energy is wasted and the effects is not expectative. According to the low-pressure mercury fluorescent lamp luminescence theory, we developed the special light source for equipment agriculture. And it is the first light source which be used in greenhouse to light crops in our country. Its emission spectrum is marching with the crop absorbing spectrum, so it has good pertinence and high efficiency, and it is the best choice to light crops. This technology has resolved the problem that the absence of light in greenhouse, and has obtained good economic and social results. On account of the lacking of red fluorescence powder on sale, we also improved and developed the red fluorescence powder which be used in special light source.
