LED street lamp now substitutes conventional light source with led array, the shell medial surface that LED is installed is the plane or the shape of evagination earthward, shell on the back adopts the good metal material of thermal diffusivity to make, great power LED is installed on the aluminium base, aluminium base is fixed on the heat-dissipating casing medial surface and solves heat dissipation problem, heat-conductive characteristic between aluminium base and the heat-dissipating casing is a problem that be difficult to solve, and the shell medial surface is the plane or the shape of evagination earthward, and glare problem also is difficult to resolve determines.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, reasonable in design, can effectively improve glare problem, light distribution effect is good, energy consumption is low, life cycle is long, easy to maintenance high-power LED street lamp.
The present invention adopts such technical solution to realize: it comprises housing and reflection shield, in housing, be provided with led light source module and circuit controller, it is characterized in that described inner walls is the light source installed surface, this installed surface is made of six strip installed surfaces that are symmetrically distributed along center line at least, described installed surface is a concave panel, described led light source module is connected on the inner walls installed surface, vertically is provided with fin on the described housing outer wall.
Since the present invention adopt inner walls at least by six strip installed surfaces that are symmetrically distributed along center line constitute a concave surface, the led light source module is connected on the inner walls light source installed surface, and vertically is provided with the structure of fin on the housing outer wall; It has overcome the deficiencies in the prior art, has effectively improved energy utilization rate, has improved photoenvironment, is one of at present comparatively desirable high-power LED street lamp.
