Due to its high brightness, wide viewing angle, long life and other characteristics, it is widely used in outdoor advertising screens and other products. Figure 1 As shown, the light board structure of a traditional LED display screen includes an LED light board 1 and several LED light sources 2. The several LED light sources 2 are electrically connected to the LED light board 1. When working, the several LED light sources 2 are powered on to emit light and display image information to the outside. When the above-mentioned light board structure is assembled, the LED light board 1 is assembled in the LED module housing, and the several LED modules are assembled in the LED box to form an LED display screen. However, the light board structure of the traditional LED display screen still has the following disadvantages when it is used in specific applications, which are described below.

[0003] First, several LED light sources 2 are electrically connected to one side of the LED light board 1 through SMD, and the connection structure is relatively fragile. The LED light sources 2 are very likely to fall off the LED light board 1 when slightly subjected to external force. Secondly, several LED light sources 2 are electrically connected to one side of the LED light board 1 through SMD at the same time. However, due to the limited area of ​​the LED light board 1, the LED light sources 2 are more likely to interfere with each other during the assembly process, which is not conducive to SMD assembly and is also not conducive to reducing the pixel pitch between the LED light sources 2. In addition, since there is an assembly gap between the LED light board 1 and the LED module housing, it is bound to affect the waterproof performance of the entire module. The light board structure of traditional LED display screens generally has the disadvantage of poor waterproof performance. The above are the main disadvantages of the prior art.

That is to say, the power connection parts of a large number of the plug-in LED light sources 100 are arranged on the device connection surface 220, which can reduce the area occupied by the light source on the light board surface 210, thereby reducing the difficulty of reducing the pixel pitch at the position of the light board surface 210. Thirdly, the plug-in structure of the plug-in LED light source 100 and other structures of the present invention can significantly improve the waterproof level of the overall LED display module.

[0026] like Figure 4 As shown, in a specific implementation, the light source part 20 includes a light source structure 40, an LED light source 45 and a bonding glue 46, wherein the light source structure 40 includes a bottom plate 41, a side wall 42 and a lens top cover 43, the side wall 42 is arranged around the bottom plate 41, the lens top cover 43 is snapped onto the side wall 42, a light source cavity 44 is formed by means of the bottom plate 41, the side wall 42 and the lens top cover 43, the LED light source 45 and the bonding glue 46 are arranged in the light source cavity 44, wherein the LED light source 45 is fixedly arranged on the bottom plate 41, the bonding glue 46 is pressed between the LED light source 45 and the lens top cover 43, and the light emitted by the LED light source 45 is irradiated through the bonding glue 46 and the lens top cover 43 in turn.

During production, the bonding colloid 46 is formed by optical glue at one time, and phosphor is arranged in the bonding disc 50 to enhance the light effect. In practice, the cross-section of the ring rib 60 is disc-shaped, and the bonding disc 50 has a top cover bonding surface 51 and a light source bonding surface 52, and the ring rib 60 has an inner side surface 61, a bottom surface 62 and an outer side surface 63, wherein the top cover bonding surface 51 is connected to the outer side surface 63, and the top cover bonding surface 51 is a plane, corresponding to the top cover bonding surface 51, and a convex lens 53 is arranged on the inner side of the lens top cover 43, and the convex surface of the convex lens 53 is pressed on the top cover bonding surface 51.

[0028] The light source fitting surface 52 is connected to the inner side surface 61 of the ring, and a light source fitting cavity 47 is formed by means of the light source fitting surface 52 and the inner side surface 61 of the ring.
