Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] figure 1 Shown is a schematic structural view of the lamp housing of the LED street lamp of the present invention.

[0030] The housing 1 is a metal U-shaped groove structure. There are side plates 3 on both sides of the bottom plate 2, and a cavity is formed in the middle. The inner surface of the cavity can also be used as the emitting surface. The circuit board module is fixed on it (see attached image 3 ), in this embodiment, there are two bottom plates 2 arranged in parallel in the housing 1, of course, according to the actual needs of street lamps, the bottom plates 2 can be set in a single row or three rows, or more.

[0031] The LED circuit board is directly fixed on the metal shell 1, and the heat generated by the LED circuit board can be directly conducted out by using the metal shell with good thermal conductivity, which can effectively control the work...

Abstract

The present invention provides a LED street lamp having high heat dispersion, including a LED source and its driving circuit, the LED source and its driving circuit are fixed on the aluminum base circuit wafer, characterized in that the aluminum base circuit wafer is fixed on the metallic lamp case, being integrity with radiator and lamp. The LED street lamp of the invention greatly enhances the radiating performance of the LED circuit wafer, reduces working temperature of LED directional light, enhances working life of LED source.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to a high-power LED street lamp with high heat dissipation performance. Background technique [0002] As a new generation of light source technology, LED lighting technology has the characteristics of energy saving, environmental protection, long life and small size, and can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes. [0003] The LED light source adopts a modular combination of self-contained constant current drive and DC drive. With ultra-low power consumption, compared with traditional light sources, it can save energy by more than 80%. [0004] The service life of LED is generally considered to be 100,000 hours under ideal conditions. In actual use, its light intensity will gradually decay with time (that is, light decay), that is, the efficiency of the LED light source to convert electrical energy into light ener...
