Problems solved by technology

However, when the air bypasses the bottom plate, it will be dispersed and cannot be concentrated, so that the heat dissipation fin group can only exchange heat with part of the air; It is not easy to be fully supplemented, so that the hot and cold air cannot be convected quickly and effectively, which hinders the heat dissipation in the central part. When the temperature rises, when the allowable junction temperature of the LED is exceeded, the final brightness of the LED will decline sharply or be damaged

Abstract

The invention discloses an LED lamp heat-radiating device which comprises a heat conducting unit and a heat absorbing unit, wherein the heat conducting unit is fixedly connected with an LED lamp and is convenient for conducting heat generated by the LED lamp; and the heat absorbing unit is fixedly connected with the heat conducting unit and used for absorbing heat conducted from the heat conducting unit when the temperature of the LED lamp rises to reach a specific value. According to the LED lamp heat-radiating device, the heat radiating effect of the LED lamp can be improved and the heat radiating efficiency of the LED lamp is increased.

Description

technical field [0001] The invention relates to the technical field of LED manufacturing, and more specifically relates to a heat dissipation device for an LED lamp. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is a semiconductor device capable of converting electrical energy into visible light. [0003] LED lighting is an emerging industry developed in recent years. Compared with the traditional tungsten filament bulb, the tungsten filament bulb uses a large current to heat the filament until it emits light, while the LED uses the electronic and electric combination in the semiconductor material to display its ability to release light, making the LED only Light with a very high brightness can be excited with a very small current. [0004] However, the biggest technical problem of LEDs at present is heat dissipation. For example, for high-power LED lamps used for street and other area lighting, the heat generated when LEDs are lit usually ...
