The purpose of this study is to probe into the effect of the application of adjustable light mounting fixture and tail-wing design of wind turbine in plant factory in order to solve the problem of controlled environment agriculture which has long been criticized for high-cost, and to achieve the purpose of energy conservation without sacrificing the quality of artificial light sources. The reflectance of the light source has been improved by the reflector to increase the proportion of the light received by the plant, and to make the light source more effective by adjustable light mounting fixture which adjusts the height of the light source automatically. The result shows that the light intensity is increased by the height of the light mounting fixture, which is increased from 23.46
