Description

Light-emitting diode lamps for improved heat dissipation

technical field

The utility model relates to a light-emitting diode lamp, in particular to a light-emitting diode that can quickly dissipate heat when the light-emitting diode is working through a thermal contact structure.

Background technique

In ordinary people's daily life, lighting equipment is an indispensable necessity for people's livelihood. Due to its widespread use and large amount of consumption, it is often raised and reviewed in terms of environmental protection issues such as saving electricity. As far as lighting equipment is concerned, the subject of the review is nothing more than: lighting efficiency and cooling effect. Among them, the lighting efficiency is related to the power consumption and lighting performance of the equipment. Among the currently known light sources, light-emitting diodes are considered to be most in line with the concept of environmental protection. The main reason is that they have the advantages of low power consumption and long working life. For lighting purposes, a single light-emitting diode is not enough to meet the needs of large illuminance lamps, so it must work collectively in the form of several complete modules, and one of the advantages of light-emitting diodes is that the temperature is relatively low during operation. After work, the heat dissipation problem of LED lamps has to be actively faced.

Contents of the invention

The purpose of the utility model is to provide a light-emitting diode lamp that can improve heat dissipation efficiency, which can use a special thermal contact structure to make the light-emitting diode module in the light fixture to dissipate heat more efficiently during operation.

The light-emitting diode lamp of the utility model that can improve heat dissipation efficiency is characterized in that it includes:

A heat conduction seat, the heat conduction seat has a top surface and a bottom surface, the bottom surface is concave to form a receiving space, and more than one protruding fixing part is formed in the receiving space, and the fixing part has at least one inclined side wall;

More than one light-emitting diode module is mainly composed of several light-emitting diodes on the surface of a circuit board, and its bottom surface is combined with the inclined side wall of the fixing part through heat-conducting glue.

With the above structure, since the heat conduction seat and the fixing part on it are made of heat-conducting metal material, the heat dissipation device can be directly installed outside the heat conduction seat, and the light-emitting diode module is formed by the heat conduction glue and the fixing part inside the heat conduction seat. Good thermal contact, so that the heat generated by the LED module can be quickly dissipated through the heat conduction seat, effectively improving the heat dissipation efficiency.
