sinking plate cooling led bracket

Abstract

The invention discloses a sunk-plate heat-dissipating LED support comprising a plastic body, a positive terminal and a negative terminal. A reflection cup is downwardly recessed from the top of the plastic body. Each of the positive terminal and the negative terminal is equipped with a die bonding portion, a clamping portion, and a soldering pin portion. Each die bonding portion and the corresponding clamping portion are located in the same horizontal plane. The die bonding portions are exposed from the bottom of the reflection cup. The clamping portions and the plastic body are fixed together. The bottom surfaces of the die bonding portions and the bottom surfaces of the clamping portions are flush with the bottom surface of the plastic body. Each soldering pin portion is upwardly bent from the corresponding clamping portion to be located in a vertical plane. The soldering pin portions are arranged on both sides of the plastic body respectively. The tops of the soldering pin portions are not higher than the top surface of the plastic body. Accordingly, the soldering pin portions are upwardly bent so as to be higher than the bottom surface of the insulated plastic body. Thus, the soldering pin portions are higher than the bottom surface of the plastic body so as to enable the LED support to have a sunk-plate structure. Soldering can be performed under a PCB so that a finished product is thinner and better in heat dissipation.

Description

technical field [0001] The invention relates to the technology in the field of LEDs, in particular to a sunken plate heat dissipation LED bracket. Background technique [0002] LED light is a semiconductor that can convert electrical energy into visible light. It has the advantages of high efficiency, pure light color, high light quality, low energy consumption, long life, and the luminous body is close to a point light source. Extremely short, wide operating temperature range, solid structure, stable and reliable performance, etc., are favored by people, and green lighting is the ecological design goal followed by the world. As a high-efficiency and energy-saving light source, LED does not need to be filled with mercury. It can reduce energy consumption and reduce greenhouse gases and other pollutants emitted into the atmosphere. It can also be used in combination with LEDs and solar cells. Therefore, it is one of the most environmentally friendly light sources and is inter...

Problems solved by technology

[0003] The traditional LED lamp has a heat sink, which is made of insulating material, and the LED chip is installed in the heat sink. Due to the poor thermal conductivity of the insulating material, the heat emitted by the LED chip cannot be dissipated in time, which seriously affects the service life of the LED lamp. Moreover, this type of LED lamp also has the defects of difficult packaging and poor light efficiency.
