Problems solved by technology
[0005] The technical problem to be solved by the present invention is to provide a base structure of a diode light-emitting device, which can improve the problem of poor heat dissipation and complicated process of the existing plastic-based light-emitting diode packaging structure. The plastic insulator is coated to make it more firmly combined with the heat-conducting body, and the body of the diode light-emitting device is changed to a metal material with good heat conduction to make it. The metal is used as the heat-conducting body, which has high temperature resistance and good heat dissipation. The increase in packaging reliability will greatly increase the heat dissipation area of the light emitting diode packaging structure, thereby enabling the diode chip of the diode light emitting device to obtain better heat dissipation effect when it is working, or it can also make the diode light emitting device of the present invention applicable For higher power product specifications

The invention discloses a seat structure and manufacturing method of diode irradiance device, thereinto the irradiance device includes seat structure, diode chip, light getting layer and lens, the seat structure possesses heat-conducting noumenon, plastic insulator and lead rack. Thereinto the plastic insulator is combined with the heat-conducting noumenon via the first mould, and then it is produced via the heat-conducting noumenon or the first sprue of the first mould in effluence moulding mode and the lead rack is coated in the plastic insulator. The lens are produced by combining the heat-conducting noumenon which is after connection from diode chip to lead rack and coating of light getting layer with the second mould.
Description
technical field [0001] The invention relates to a base structure of a diode light-emitting device and a method for manufacturing the diode light-emitting device, in particular to a method for manufacturing a diode light-emitting device for high-power lighting and its structure. Background technique [0002] In recent years, due to the continuous improvement of product characteristics of light-emitting diode luminous efficiency, the market for light-emitting diode applications has grown significantly. There are two main growth drivers for LEDs to have such a high market growth rate. The first is the replacement between LEDs and cold cathode ray tubes (Cold Cathode Fluorescent Lamps; CCFLs) in the LED display backlight market; It is a replacement between light-emitting diodes and incandescent bulbs or fluorescent lamps in the general light source market. In the above two growth driving markets, LEDs have the advantages of environmental protection, energy saving, and good colo...
