Radiating structure of LED (Light-Emitting Diode) street lamp

Abstract

The invention provides a radiating structure of an LED (Light-Emitting Diode) street lamp, which belongs to the technical field of illumination and is used for solving the problems of degradation of the service life, even burn-down and the like of an LED street lamp caused by non-timely radiation existing in the conventional LED street lamp. In the radiating structure of the LED street lamp, the street lamp shell comprises a lamp shell and a plurality of installing plates where LED chips are fixed, wherein the radiating structure comprises radiating plates, an auxiliary radiating tube and a fan; the radiating plates are fixed on the end face of one end of the installing plate; the auxiliary radiating tube is positioned in the lamp shell; the two ends of the auxiliary radiating tube are fixed on the lamp shell, and pass through the lamp shell; an auxiliary radiating plate is fixed in the auxiliary radiating tube; the fan is fixed in the auxiliary radiating tube; the fan faces the auxiliary radiating plate; heat-conducting bars which correspond to the radiating plates one by one are fixed in the lamp shell; one ends of the heat-conducting bars are pressed against the radiating plates; and the other ends of the radiating bars pass through the auxiliary radiating tube, and are pressed against the auxiliary radiating plate. The radiating structure had the advantage that an LED chip of the LED street lamp can work constantly at a safe temperature.

Description

technical field [0001] The invention belongs to the technical field of lighting, and relates to an LED street lamp, in particular to a heat dissipation structure of the LED street lamp. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. High-pressure sodium lamps emit 360° light. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great signific...

AI Technical Summary

Problems solved by technology

Existing radiators for LED street lamps generally use the surface of the lamp shell to dissipate heat in order to improve the heat dissipation effect. However, there is air between the heat dissipation substrate of the LED chip and the lamp shell to isolate heat transfer, and the heat dissipation effect will be greatly reduced, resulting in the use of LED street lamps. Decreased lifespan, or even burned
