Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to the improvement of the dot matrix LED structure, especially a production and assembly convenience, and the use of less glue can save production costs, and the LED after the circuit board is glued A partially domed light transmissive body is formed on the top, and the pair of outer shells can penetrate through the shell surface and have a light-concentrating function. It has a good light effect, and can be partially removed and replanted in the event of a failure to improve production yield. . [Previous technology] According to the conventional point matrix L E D, the shell mainly includes: a shell which is covered with light emitting LED chips arranged at intervals, and the other side is provided with rows of pins for external control power. The specific method is as shown in the eighth figure. The ED grains B are arranged on a circuit board A with a matrix distribution. A plurality of glue injection holes C are arranged on the board. Row pin D, and then place the board into a concave outer shell e. After the board is glued, it will be glued into a block structure. The finished product can be provided with concave and convex inserts F, G on the four sides of the block outer shell. And multiple pieces and a certain area of the display. However, the conventional structure has the following disadvantages in production and use:

1 · Short protrusions are formed inside the device body to pre-assemble the ED grains of the frame-separated circuit board. Before assembly, the surface of the shell must be covered with a release layer, and it is torn off and colored (brushed) after forming. The LED dot matrix can be easily seen, and the whole method is troublesome. φ 2 · When pouring glue, the dot matrix l E D is only tangent to the shell surface, and there are no protrusions. At startup, the angle of the bright point of the light is also limited, and it can only be in local points and cannot spread outward. " 3 · The finished product is glued into blocks, so as long as a single L E D failure occurs
