Abstract

The invention relates to an LED chip heat dissipation structure. The structure includes an LED chip, a heat dissipation cushion and a heat dissipation substrate. The heat dissipation cushion is provided with a groove, and the LED chip is disposed in the groove. Part of the side surface and the bottom of the LED chip are in contact with the heat dissipation cushion. The structure is characterized in that the heat dissipation cushion is at least equipped with a heat dissipation pin, the heat dissipation substrate is equipped with a groove, and the heat dissipation pin is inserted into the groove. Through adoption of the pin and the groove, the heat dissipation cushion and the heat dissipation substrate can be combined together. The pin and the groove achieve fixing and combining effects. Moreover, thermal conduction is achieved when the pin and the groove are in contact, that is to say, heat dissipated from the bottom and the side of the chip is conducted to the heat dissipation substrate through the heat dissipation cushion. Therefore, a heat dissipation function is achieved.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to designing a heat dissipation structure for LED chips. Background technique [0002] Now LED lamps have been widely used in daily life, and have gradually replaced incandescent lamps in the field of lighting. At the same time, LEDs are also actively promoted in other fields. The LED light source has the characteristics of high brightness and energy saving, so it is an environmentally friendly lighting. However, LED as a light source itself has certain defects, one of which is heat dissipation, which directly affects the life of the LED light source itself. Therefore, if the heat dissipation problem can be effectively solved, it has always been the goal of performance pursuit. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an LED chip heat dissipation structure, which includes an LED chip, a heat dissipation pad and a heat d...
