his paper aims to probe into the feasibility and applying strategy of the energy-efficiency optimization of college dormitory lighting system in Chongqing. It takes a college dormitory located in chongqing as an instance, through questionnaire and field investigation, the conclusion indicated that the indoor illumination during the daytime cannot meet the relevant national standards. And over 80 percent of the students are unsatisfied with the indoor lighting. The research on the optimization program of Photoconductive lighting system and energy efficiency lamp system demonstrate these two programs can save 5.7 tons of standard coal per year and 1.67 respectively. Then model the photoconductive lighting system. Finally it takes the Photoconductive lighting system and energy efficiency lighting systems promoted and compared in college dormitory of Chongqing to draw a conclusion that the annual savings of the system are approximately 21.8-22.4 million kwh electricity which equals to 8.72-8.94 one thousand tons of standard coal. This quantity is equivalent to a half of the electricity consumption of Chongqing Dadukou 2012 January-April.
