Technical Field

[0001] The utility model belongs to the technical field of point light sources, and particularly relates to an LED point light source grid screen. Background Art

[0002] In the existing market, the point light sources applied to energy-saving decorative lights, exterior wall decorations, etc. or display screens are usually single-emitting light sources, which are then welded together respectively. By controlling the optional light emission of each light source, various variable animation effects can be formed. However, this traditional point light source has two disadvantages. One is that the embellishment effect is poor and more complex and delicate animation effects cannot be achieved. The second is that disassembly, installation and maintenance are relatively inconvenient. Content of the Utility Model

[0003] The purpose of the utility model is to provide an LED point light source grid screen, comprising:

[0004] A bottom shell; and

[0005] An outer shell, which is hermetically connected and assembled with the bottom shell and fixed by ultrasonic welding. A receiving space is formed inside the outer shell;

[0006] A PCB board is arranged in the receiving space and is limited and fixed between the bottom shell and the outer shell. A microcomputer chip is configured on the PCB board, and a lamp bead is arranged at each of the four corners of the PCB board. Each lamp bead is electrically connected to the microcomputer chip and is independently controlled by the microcomputer chip. The light emitted by the lamp beads presents an effect through the outer shell;

[0007] First connection parts and second connection parts are respectively formed at both ends of the outer shell. Adjacent outer shells are connected by clamping the first connection parts and the second connection parts.

[0008] Further, the middle part of the PCB board is a circular main board, and four support plates are evenly formed and extended along the circumferential direction on the periphery of the main board. The lamp beads are welded and fixed on the outer ends of the support plates.

[0009] Further, the outer shell respectively includes a first outer shell main body and a second outer shell main body corresponding to receiving the main board and the support plates. A positioning cylinder is further formed on the second outer shell main body, so that when the PCB board is received in the outer shell, the lamp beads are correspondingly inserted into the positioning cylinder.

[0010] Further, a limiting plate is further arranged inside the first outer shell main body. When the PCB board is received in the outer shell, the main board is attached to the limiting plate.

[0011] Further, the bottom shell includes a first bottom shell main body and a second bottom shell main body respectively corresponding to and adapting to the first outer shell main body and the second outer shell main body. A positioning plate is convexly formed on the first bottom shell main body. When the bottom shell is installed in the outer shell, the positioning plate is attached to the back surface of the main board.

[0012] Further, positioning posts are provided on the second bottom shell body, and the positioning posts abut against the rear part of the support plate.

[0013] Further, it further includes a first wiring terminal and a second wiring terminal. The first wiring terminal and the second wiring terminal are respectively clamped on both sides between the bottom shell and the outer shell and are electrically connected to the PCB board.

[0014] The beneficial effects of the present utility model are as follows:
