Abstract

The invention relates to high power LED street lamp. It includes shell, circuit board, LED, and lens unit. The LED and lens unit are set in circuit board to form many LED light source modules. The adjacent two are set in the basal body set many carrying surfaces formed by edge carrying surface. The included angle between LED emergence normal and the center plane of the basal body end surface is 45-60 degree.

Description

【Technical field】 [0001] The invention relates to the technical field of LED lighting, more specifically, to a high-power LED street lamp. 【Background technique】 [0002] With the development and maturity of LED technology, the performance index of LED has been greatly improved day by day. At present, the luminous efficiency of white LED has reached or even exceeded the level of luminous efficacy of ordinary incandescent lamps, and the luminous flux has also increased significantly, which has made LEDs gain a lot of attention in the field of lighting. Wide range of applications. Compared with the energy-saving lighting fixtures used by general photovoltaic power sources, LED has the outstanding advantages of long life, low heat generation, not easy to damage, low power consumption and more energy saving. People call it the fourth generation of lighting that replaces fluorescent lamps and incandescent lamps in the 21st century. light source. [0003] At present, so-called h...
