Problems solved by technology

[0003] At present, there are two methods for manufacturing LED light sources: method 1, packaging the LED chip into a plug-in or patch lamp bead, and then assembling the lamp bead, circuit board, heat sink, power supply, housing and other materials into an LED lamp; method 2. Directly fix the LED chip on the metal or ceramic substrate with a printed circuit layer, then wire welding, dispensing, and curing to form an LED light-emitting module, and then connect the LED light-emitting module to the circuit board, heat sink, power supply, housing and other materials Assembled into LED lamps; method 1 requires two packaging processes of lamp bead packaging and LED lamp assembly to manufacture LED lamps, with many technological processes, high cost, and complicated heat dissipation design; method 2 manufactures LED lamps, although the LED lamp bead packaging process is omitted. However, there are more manufacturing processes of aluminum substrates (or ceramic substrates) with circuit board printing layers, and the process flow is a bit more, radiators are still required, and the cost is also high

Abstract

A method for manufacturing an LED light source is characterized by sequentially comprising the following steps that (a) a substrate is made of transparent materials, wherein a groove is formed in the surface of the substrate; (b) the bottom of the groove is coated with fluorescent gum; (c) an LED chip is fixed to the fluorescent gum at the bottom of the groove; (d) electrodes of the LED chip are connected in series by a metal wire; (e) the LED chip and the metal wire are coated with fluorescent gum. According to the method for manufacturing the LED light source, a traditional manufacturing process of an LED light source is simplified and material consumption is reduced.

Description

technical field [0001] The invention relates to the field of LED light sources, in particular to a method for manufacturing an LED light source. Background technique [0002] LED is a kind of semiconductor light source, which has the advantages of energy saving, small size and long life. In recent years, it has gradually replaced traditional incandescent lamps and will become the main lighting source in the future. [0003] At present, there are two methods for manufacturing LED light sources: method 1, packaging the LED chip into a plug-in or patch lamp bead, and then assembling the lamp bead, circuit board, heat sink, power supply, housing and other materials into an LED lamp; method 2. Directly fix the LED chip on the metal or ceramic substrate with a printed circuit layer, then wire welding, dispensing, and curing to form an LED light-emitting module, and then connect the LED light-emitting module to the circuit board, heat sink, power supply, housing and other materials...
