Problems solved by technology
Traditional LED lighting design such as Figure 11 As shown in , in addition to the LED bulb 70, a light reflector 71 (lampshade) and an optical lens 72 (transparent cover) must be installed to guide and emit the light emitted by the LED bulb 70, and the light is reflected by the light reflector 71. The penetration of the optical lens causes double loss, which affects the final luminosity of its emission. How to reduce optical loss is an important factor to improve LED lighting efficiency

Embodiment Construction
[0040] The present invention is a high-brightness light-emitting diode (LED) lighting device and manufacturing process (such as Figures 1 to 4A , Figure 4B shown in ), mainly by Figure 4A Composed of light-emitting modules, including:
[0041] A heat-conducting fixing seat 10 is used to fix the light-emitting diode (LED) light source body and dissipate the heat of the LED into the air. Figure 5 As shown, in combination with a lampshade 40, the heat of the LED is transferred to the lampshade through the circuit board and the heat-conducting fixing seat, and is scattered into the air by the lampshade; a circuit board 11 is arranged on one side of the heat-conducting fixing seat 10;
[0042] A welding fixing plate 20 for welding LED manufacturing process, on which a plurality of LED light bulb holes 21 are arranged, welding holes 22 are arranged between each LED bulb holes 21, and fixing screw holes 23 are respectively set on the periphery of the welding fixing plate 20 , ...

The invention relates to a high-brightness light-emitting diode, and relative production, wherein it is formed by lighting modules; said module is formed by light source, permanent fixing plate, transparent plate, fixing screw, waterproof compressing material and thermal-conductive fixing base, to form the sealing element; the light source is formed by welding several LED on the circuit board; the permanent fixing plate compresses the LED with the thermal-conductive fixing base; the permanent fixing plate has several holes whose inner surfaces are made into reflective surface, or sheathed with one layer of reflective plate, to reflect the light of LED; the transparent plate is between the permanent fixing plate and the cover plate; the cover plate and the waterproof compress material, via fixing screws are fixed with the permanent fixing plate; the back of circuit board contacts the thermal-conductive fixing base, via waterproof compress material; and the lighting modules can be connected with one light lamp shade.
Description
technical field [0001] The invention relates to a high-brightness light emitting diode (LED) lighting fixture device and manufacturing process, which can mainly improve the brightness of the lighting fixture, and integrate three functions of heat dissipation, optics and weather resistance into one, so as to ensure that the base of the LED bulb and the circuit The permanent close contact of the board enhances its heat dissipation function, ensures product reliability and life, and improves optical efficiency and weather resistance. Background technique [0002] High-brightness LED lighting can save electricity and is a next-generation lighting technology that will be widely used in the future. In addition to saving energy, LED has the advantage of long life, but the premise is that the heat dissipation must be good, otherwise it is easy to burn out, especially the wick temperature that LED bulbs can tolerate usually does not exceed 120 ° C, which is much lower than traditiona...
