As time goes by, outdoor lighting has become the method to enhance the city characteristic at night. However, improper lighting design or use may cause light pollution which includes sky glow, light trespass, and glare. Furthermore, the reflecting light from glass and building walls, and the glare from interior lighting are also the parts of light pollution. It would affect humans daily lives, cause uncomfortable feeling, disturb night ecosystem, consume more energy and increase environment load. Since the relative studies of light pollution are at the initial stage in Taiwan and people have not generally pay much attention to this issue, the purpose of this study is to diminish the impact of environment from light pollution. Firstly, it collected current international issues and standards of light pollution as references. Secondly, it surveyed and analyzed conditions of light pollution in Taiwan. Finally, according to above results, it proposed suggestions and strategies of reducing light pollution. These results could be used to improve existing lighting design and enhance the lighting quality in the future.
