The invention discloses a manufacturing method of LED (Light Emitting Diode) lighting source and LED lighting source. The manufacturing method of LED lighting source comprises the following steps: step A: laying a circuit on the upper surface of a first base plate, and presetting multiple LED packaging positions on the upper surface, wherein each LED packaging position comprises a solid crystal position and a positive electrode welding spot as well as a negative electrode welding spot which are connected with the circuit; step B: fixing a second base plate which is provided with multiple LED packaging holes on the upper surface of the first base plate, wherein the positions of the LED packaging holes correspond to the positions of the LED packaging positions; step C: fixing an LED chip on each solid crystal position, and connecting the positive electrode and negative electrode of the LED chip to the positive electrode welding spot and the negative electrode welding spot respectively; and step D: covering a fluorescent glue above the LED chip. By the LED lighting source and the manufacturing method thereof disclosed by the invention, multiple LED chips are packaged on a composite board formed by combining the first base plate and the second base plate, the brightness of the LED lighting source is improved, and the material cost and processing cost are lowered.
Description
technical field [0001] The invention relates to the field of LEDs, in particular to a method for manufacturing an LED lighting source and an LED lighting source. Background technique [0002] Most LED light sources package an LED chip in a bracket to form a single LED light source structure. This kind of LED light source is usually used for backlight display, that is, multiple LED light sources are combined in a certain order to cooperate with the light guide plate. When such a single LED light source is used for lighting, it is difficult to meet the use requirements due to the low brightness, so a combined structure of multiple single LEDs must be used. However, this will not only increase the cost of the bracket, but also complicate the manufacturing process. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a method for manufacturing an LED lighting source that improves LED brightness and reduces costs, and...
