Manufacturing method of LED backlight positioning structure that is easy to adjust

An easy-to-adjust LED backlight positioning structure

technical field

1. The present utility model relates to the technical field of LED backlight sources, in particular to an LED backlight source positioning structure that is easy to adjust.

Background technique:

2. LED backlights are widely used. In the prior art, common LED backlights are mainly composed of PCB substrates and LED bulbs. The common manufacturing method of LED backlights is to install multiple LEDs on the PCB board, and then install multiple PCB The plates are mounted inside the housing by bolts or glue.

3. Chinese patent document cn209278983u discloses a LED backlight, including a backlight shell, a plurality of pcb boards are mounted on the backlight shell, a plurality of led lights are mounted on the pcb board, and a plurality of mounting boards are fixedly mounted on the backlight shell , There are a plurality of installation grooves on the installation plate, the same pcb board is fixedly installed in the two installation grooves on the same horizontal axis, and two rectangular grooves are opened on the inner walls of both sides of the installation groove, and the sliding in the rectangular grooves A rectangular block is installed, one end of the spring is welded on one side of the rectangular block, and the other end of the spring is welded with the inner wall of one side of the corresponding rectangular slot, and the inner wall of one side of the rectangular slot is provided with a rectangular hole. The utility model has the advantages of simple structure and convenient operation, can quickly install the pcb board, improves the work efficiency, is convenient for maintenance, and is not easy to cause damage to the backlight source, the buffer pad protects the pcb board, and the anti-skid pad increases the rectangular block and the pcb The friction of the board makes the installation of the pcb board more stable, and the reflector increases the illumination brightness of the led light, but the patent mainly has the following two shortcomings. The slats are not easy to remove, which makes it difficult to repair when the LED light source on the pcb slats is damaged.
