The width between the two longitudinal sides of the board 120, that is, the width of the middle longitudinal gap of the two longitudinal sides, A is the width of each longitudinal side of the PCB light board 120, and the width between the two longitudinal sides of the PCB light board 120 is equal to each longitudinal side. Double the width, ie H=2A.

The U-shaped structure can ensure the symmetrical illumination of the PCB light board 120. The integral light board avoids the necessary connection and process of the block splicing, the electrical connection is simple and direct, and the area of the used material of the light board is effectively controlled. When the U-shaped lamp board structure is produced and typeset, as shown in FIG. 6, the U-shaped lamp board and the U-shaped lamp board can be embossed by the convex and concave of the U-shaped lamp board, thereby realizing the material utilization ratio of the production of the material, and greatly reducing the production cost. .

The width between the two longitudinal sides of the PCB light board 120 is twice the width of each longitudinal side, and the middle part has a wider space, and the middle part which is vacated can be used as a driving power source, and the driving power source is placed at the center.

As shown in FIG. 4, a plurality of LED lamp beads 130 are symmetrically disposed on the two longitudinal sides. Ensure that the lamp board is symmetrical and evenly illuminated. The width of the lateral side of the PCB light board 120 is smaller than the width of the longitudinal side, and the horizontal side of the PCB light board 120 is not arranged with the lamp bead, and the electrical circuit of the legs of the U-shaped light board is mainly connected as a whole. The narrow width of the lateral edges saves materials and further improves material utilization. In addition, the width of the lateral side portion is narrow, and the required installation space outside the lateral side does not need to be reserved a lot. According to the symmetry of the light-emitting area, the LED light board assembly can be quickly and directly arranged, as shown in FIG.
