Research of Energy Efficiency Evaluation for LED Light and Luminaires
Abstract：For improving the energy efficiency of LED light and luminaire,it is necessary to optimize their light distribution design according to the real lighting surroundings.In this way,power density and energy consumption can be further reduced while illuminance requirements are met.By comparing lighting effects of LED street lights with different distribution,high pressure sodium lamp and LED street light,it was verified that the light distribution design of LED luminaire is important for energy saving,and a scientific method for energy efficiency evaluation of LED lights and luminaires is given.
