BACKLIGHT MODULE AND LED PACKAGING STRUCTURE

摘要

A backlight module and an LED packaging structure. The backlight module comprises a PCB (200) and an LED (100) arranged on the PCB (200). The PCB (200) is provided thereon with fixing structures for fixing the LED (100), and the LED (100) is provided thereon with butting structures used for butting with the fixing structures. Each of the fixing structures is a fixing bracket (210) arranged on the PCB (200), a clamping groove (217) is formed in the fixing bracket, and the inner wall of the clamping groove (217) is provided with a convex part (212). Each of the butting structures is a fixing part (110) arranged on the two side surfaces of the light-exiting surface of the LED (100), and a clamping strip (111) is formed on the fixing part. The clamping strips (111) on the two side surfaces of the LED (100) are fixed in a mated manner to the clamping grooves (217) respectively. Because the fixing structures and the butting structures are respectively arranged on the PCB and the LED, the LED can be removably installed on the PCB directly without SMT welding, thereby facilitating the replacement of the LED.
