Abstract
The disclosure provides a LED light bar configured in a backlight module, including a light bar circuit board and LEDs disposed on the light bar circuit board. A long side of the light bar circuit board is defined with a nick. The nick forms a first embedding section. A heat dissipation section is disposed in the first embedding section. The disclosure further provides a backlight module, including a light guide plate disposed in a frame, further including the LED light bar configured in a backlight module. Compared with the prior art, the heat dissipation section is disposed on the light bar circuit board to conduct heat of the LEDs out of the backlight module, which reduces the heat in the center of the LED light bar and improves heat dissipation of the backlight module, further preventing the optical films from being wrinkle and dark regions appearing in the backlight module.
