Abstract

The invention provides an LED street lamp with high heat dissipation performance, comprising a heat dissipation housing formed by the upper end and the lower end of an all-in-one part, LED lamps arranged in the heat dissipation housing and on a base plate and a control circuit connected with the base plate, wherein the control circuit is fixedly connected in the heat dissipation housing. The LED street lamp is characterized in that the base plate is fixedly connected with the inner wall of the heat dissipation housing; a first fin array is arranged on the rear surface of the upper end and second fin arrays are respectively arranged at the two sides of the lower end. The LED street lamp solves the problems of poor heat dissipation effect and environmental pollution of the existing LED street lamps. The fins uniformly distributed in two channels ensure the LED lamp bodies to have good heat dissipation effect and the service lives of the LED lamp bodies to be prolonged; the titanium layers coated on the fins ensure the lamp bodies to have better heat dissipation effect, have the effect of corrosion resistance and can not pollute the environment; and as the direct heat conduction structure exists between the base plate and the heat dissipation housing, the LED lamp bodies have good heat dissipation effect and the service lives of the LED lamp bodies are prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED street lamp with high heat dissipation performance. Background technique [0002] At present, LED street lamps are widely used in the field of lighting. Traditional LED street lamps dissipate heat from their light sources through heat conduction through heat pipes arranged between the substrate and the housing. However, this heat transfer structure is complicated, and the processing cost is high. The thermal efficiency is also relatively low. Due to the indirect heat transfer, it is difficult to quickly remove the heat trapped in the LED lampshade. The accumulated heat will cause the light source to cause poor heat dissipation, low light efficiency, which is not conducive to energy saving, and the device is easy to age. The service life of LED street lamps is shortened, and at the same time, the heat conduction structure has strict requirements on the material performance...
