Abstract：LED has the advantages of safety, longevity, high efficacy and controllable and so on. In the latest years, it has been become a hotspot of product research and development on LED luminaries for road lighting. Sharing the requirement of road lighting and the benchmark which evaluation the characteristic of luminaire lighting distribution, and the analyses of measured datum, the article open out the key manner for estimate the photometry of the LED road lighting luminaire. And this key manner is >;F} >_i
also use for analyzing the status of LED road lighting luminaire from 2007 till now. J`C 2}$
