Abstract

The invention relates to a highly-efficient radiation high-power light emitting diode (LED) packaging structure. According to the technical scheme provided by the invention, the highly-efficient radiation high-power LED packaging structure comprises a transparent substrate and a bottom plate; a plurality of LED luminous chips are arranged on the bottom plate; and the transparent substrate is positioned on the side, provided with the LED luminous chips, of the bottom plate, and is covered on the LED luminous chips in a pressing way. In the highly-efficient radiation high-power LED packaging structure, the LED luminous chips are arranged between the transparent substrate and the bottom plate, and can form a single-layer or multi-layer structure; radiation substrates are arranged on the two sides of the LED luminous chips, adopt silvered plates or silver plates, and have high thermal conductivity; the transparent substrate, the radiation substrates and the bottom plate can dissipate the working heat of the LED luminous chips at the same time so as to increase a radiation area, prolong the service life of the LED luminous chips and reduce light emitting cost, and may not influence the light emitting rate of the LED luminous chips 2; and the highly-efficient radiation high-power LED packaging structure is simple and compact, convenient to arrange and use, safe and reliable.

Description

technical field [0001] The invention relates to an LED packaging structure, in particular to a high-power LED packaging structure with efficient heat dissipation, and belongs to the technical field of LED packaging. Background technique [0002] At present, with the development of LED material epitaxy and chip technology, LED has shown a good application prospect, especially high-power LED, its application field has been continuously expanded, and has been widely used in landscape lighting, miner's lamp, street lamp, emergency street lamp and other fields. [0003] LED is a special kind of diode. Its core part is a chip composed of P-type semiconductor and N-type semiconductor. These semiconductor materials are pre-produced by implantation or doping processes to produce a P / N junction structure. In the P / N junction of some semiconductor materials, the current in the LED can easily flow from the P pole to the N pole, and two different carriers, namely holes and electrons, flo...
