Embodiment Construction

[0027] Firstly, adopt the bracket whose bottom of the reflective cup body is not on the same plane; that is, sink down at least one height at any position of the bottom of the reflective cup body to form a bracket for a small reflective cup that can be placed with one or more tricolor LED light-emitting chips Above, thicken the frame composed of the cup body (6), each pole lead wire (7), (8), (9), (10) to more than 1.2mm; position, use wires to connect the chip electrodes with the lead frame; finally use the overall transparent epoxy resin to package into various shapes and shapes according to different requirements; if surface mount is used, then bend from (19), and then For surface mount, over reflow soldering.

[0028] The plane for fixing the illuminants of the three-primary-color LED light-emitting chips is non-planar, and at least one position (13) is not on the same plane as the fixing positions (21) of the luminous bodies of other primary-color LED light-emitting chips...

Abstract

The invention provides a method for producing three-color light-emitting diode for display screen, which relates to the production method of LED; including the following steps of: A. using a stand with reflection cup body bottom parts which are not in one flat, that is the stand on which an arbitary position of bottom of the reflection cup body subsidises one height at least and forms a small reflection cup for imbedding one or multiple luminous chips; thickening the frame composed of cup body (6), every electrode lead wire (7), (8), (9), (10) up to more than 1.2mm; B. fixing every color LED luminous chip on corresponding position inside the cup body respectively, connecting the electrode and lead with conducting wire; C. packaging into completed product with various shapes with monolithic transparent epoxide resin. The three-color light-emitting diode provided by the invention has the advantages of long service life, energy conservation, green environment friendly pollution-free, color enrichment and high color purity, and the lightness and color of the diode can be adjusted arbitrarily used with control circuit and environment friendly clean energy.

Description

Technical field: [0001] The invention relates to a method for manufacturing light-emitting diodes, in particular to a method for manufacturing three-primary-color light-emitting diodes for display screens. Background technique: [0002] Due to the continuous update and progress of LED light-emitting diode technology, it has been widely used in real life, such as indoor and outdoor display screens, various landscape lighting, industrial lighting, medical lighting, etc. With the rapid development of LED technology, LED is now approaching general lighting. With its high theoretical light efficiency, it has far surpassed traditional incandescent lamps, even fluorescent lamps. Since the 2008 Olympic Games, LEDs have been widely used in various display fields. There are many ways to realize the existing LED display technology. The common method is to use at least two single LEDs in red light, green light, and blue light to combine together to form a pixel point through a certain...
