Radiating method of LED radiator and radiator for implementing same

Abstract

The invention discloses a radiating method of an LED radiator and also discloses the radiator for implementing same, and the radiator comprises a radiating support and a plurality of LED lights. A metal basal plate the width of which is slightly smaller than that of the radiating support is arranged on the front side of the radiating support, and a printed circuit which can be connected with the LED lights is longitudinally arranged in the middle position of the metal basal plate; the LED lights are welded on the printed circuit at intervals, and are fixed on the metal basal plate to form an integral structure. The invention has simple structure, and the metal basal plate and the radiating support are separately arranged to be convenient for manufacture; the printed circuit is arranged onthe metal basal plate, and the LED lights can be directly welded, and can be fixed on the radiating support by radiating silicon grease so as to form an integral radiating structure; the heat of the LED lights can be rapidly radiated, thereby reducing the speed of LED brightness decline and greatly prolonging the service life of the LED lights; the LED lights can be used for more than 50000 hoursat least by practical tests.

Description

Heat dissipation method of LED radiator and radiator implementing the method technical field The invention relates to an LED heat sink, in particular to a heat dissipation method for an LED heat sink and a heat sink implementing the method. Background technique Most of the traditional road lamps use high-power mercury lamps, metal halide lamps or high-pressure sodium lamps as light sources. High, lighting effects are unsatisfactory in terms of color rendering and anti-glare performance. At the same time, the development of semiconductor light-emitting diodes (LEDs) is extremely rapid. In recent years, the luminous efficiency of some LEDs has greatly exceeded that of incandescent lamps, and even exceeded that of fluorescent lamps. Compared with the traditional floodlight electric light source, the LED light source is basically non-toxic, non-electromagnetic pollution, and has many advantages such as small size, low energy consumption, high luminous efficiency, relatively l...
