Problems solved by technology
Some of the existing mainstream substrate connection methods are: 1. Directly solder the DC line to the COB substrate. The advantage is that the process is simple and easy to operate. The disadvantage is that the efficiency is low, the quality is unstable, and it is easy to damage the COB, and it is only suitable for small batch production.
2. Using the existing complete set of COB connectors has the advantages of reliable performance and can be used in batches, but the disadvantages are high price, large space occupation and poor matchability

Embodiment
[0025] Embodiment: a kind of assembly structure of LED light source module, such as Figure 1~4 As shown, it includes an LED light source board 1, a printed circuit board 2 with a hole in the center, and a fixed plate 3 with a hole on the plate surface. There are three screw holes 35 on the periphery of the bottom surface of the fixed plate 3 for connecting with LED lamps. The boss 31.
[0026] LED light source board 1 is provided with LED light source 11 and two pads 12a of different polarities. Specifically, LED light source board 1 includes LED light source 11 and substrate 13 carrying LED light source 11. Substrate 13 is square, and the pads 12a is arranged at two opposite corners of the substrate 13; there is a pad 12b corresponding to the LED light source board 1 on the bottom surface of the printed circuit board 2, and the LED light source board 1 and the printed circuit board 2 are bonded and fixed with red glue, and the two The pads 12a and 12b of the latter are cond...

The invention discloses a rapid assembling method and assembling structure for an LED light source module. An LED light source board and a printed circuit board are in conductive connection with through tin or conductive adhesives, and meanwhile an LED light source is exposed out of a hole in the center of the printed circuit board after the LED light source board and the printed circuit board are pasted and fixed. A fixed disc with a hole formed in the disc face covers the printed circuit board, the LED light source and a terminal, used for being connected with a power source, on the printed circuit board are exposed out of the hole in the fixed disc, two bosses are arranged on the bottom face of the fixed disc, the bosses penetrate through the hole of the printed circuit board and abut against the LED light source board, and a plurality of protruding columns which are used for being connected with an LED lamp and provided with screw holes are arranged on the periphery of the bottom face of the fixed disc. Therefore, the LED light source board, the printed circuit board and the fixed disc form the LED light source module capable of being assembled on the LED lamp. When the LED light source module is assembled on the LED lamp, the fixed disc abuts against the LED light source board by the aid of the bosses and then is locked on the LED lamp through screws, the printed circuit board is prevented from being stressed, and circuit connection is more stable.
Description
technical field [0001] The invention relates to the technical field of LED lighting, in particular to a rapid assembly method and assembly structure of an LED light source module. Background technique [0002] LED has been widely used in urban public lighting, office and indoor lighting and other fields due to its many advantages such as energy saving, environmental protection, light control, solidification, and long life. Low structural cost, efficient production performance and reliable design structure have always been the focus of discussion in the R&D and production technology departments for the LED lighting industry. [0003] As the LED industry continues to mature, automated production is the general trend; this puts forward higher adaptability requirements for product structure design. Some of the existing mainstream substrate connection methods are: 1. Directly solder the DC line to the COB substrate. The advantage is that the process is simple and easy to operate...
