Heat dissipation structure of high-power light-emitting diode (LED) illuminating lamp

Abstract

The invention discloses a heat dissipation structure of a high-power light-emitting diode (LED) illuminating lamp, which belongs to the technical field of electrons. The heat dissipation structure comprises a cylindrical LED chip base-column, a heat dissipation shell, a retaining washer and a screw opening, wherein the external surface of the heat dissipation shell is provided with a micro-slot structure; the heat dissipation shell is sleeved outside the cylindrical LED chip base-column; the retaining washer is sleeved on the front end of the chip base-column, and connected with the heat dissipation shell by bolts; the screw opening is connected and fixed with the heat dissipation shell by the bolts, and connected with the chip base-column by contact points; the external surface of the rear part of the chip base-column is provided with a cylindrical contact curved surface which is fitted with the heat dissipation shell, and the heat dissipation shell is provided with fins. By using the heat dissipation structure of the invention, the heats gathered on the chip part can be quickly reduced, thereby minimizing the temperature of the high-power LED lamp; and because the chip base-column is detachable, when the LED chips reach the usage life-spans thereof or are damaged because of other reasons, the whole LED lamp is not required to be replaced but just replacing the chip base-column.

Description

technical field [0001] The invention relates to an electronic heat dissipation structure, in particular to a combined LED lamp radiator, which belongs to the technical field of electronics. Background technique [0002] Light-emitting diode (LED), also known as semiconductor lamp, is a light-emitting device that can directly convert electrical energy into light energy and output it. It is a cold light source without filament. LED is known as a new generation of energy-saving light source that can replace traditional light sources. In addition to the advantages of saving energy, LED also has the characteristics of long life, small size, safety and reliability, environmental protection and pollution-free, multi-purpose, and easy control. LED has a wide range of uses and can replace traditional light sources in many occasions. When high-power LED lighting fixtures appear, the speed at which they replace traditional light sources has been accelerated, and it has also made it po...
