介质填充技术路灯及其应用探讨

Discussion on Street Lamps with Medium Filling Technology and Its Application

通过填充折射率匹配介质来减少界面反射损失并提高LED芯片光线利用率,从而得到高光效的路灯。本文将对基于此项技术的高光效路灯作技术简介,并依据灯具填充前后的配光变化、光通量变化,从亮度和照度两个评估体系作应用探讨。

By filling refractive index matching medium to reduce interface reflection loss and improve the light utilization of the LED chip,the street lamps with high luminous efficiency can be obtained.In this paper,the high luminous efficiency street lamp based on this technology will be briefly introduced,and the application of the two evaluation systems of brightness and illumination will be discussed according to the change of light distribution and luminous flux before and after the lamp is filled.
