Abstract

The invention relates to the technical field of LED (Light Emitting Diode), and specifically relates to an LED backlight module. The LED backlight module comprises a bottom plate and a side plate as well as a reflective film, a light guide plate and a diffusing plate which are sequentially arranged on the bottom plate, wherein an LED light source assembly is arranged at the side edge of the light guide plate; the side plate, the bottom plate and the diffusing plate form an accommodating space; the reflective film, the light guide plate and the LED light source assembly are located in the accommodating space. The LED backlight module further comprises a radiating assembly which comprises a heat guide plate and a first silica gel gasket arranged between the side plate and the LED light source assembly, wherein the first silica gel gasket is installed on the heat guide plate, and the LED light source assembly is respectively contacted with the heat guide plate and the first silica gel gasket. As the heat guide plate and the first silica gel gasket are arranged between the side plate and the LED light source assembly, radiation is better, and the service life of the LED light source assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED backlight module. Background technique [0002] Light Emitting Diode (LED) is a solid-state semiconductor device that can convert electrical energy into visible light. It is widely used in display screens, traffic signals, display light sources, automotive lights, LED backlights, and lighting sources. Semiconductor lighting has remarkable characteristics such as long life, energy saving, green environmental protection, rich colors, and miniaturization. [0003] The existing LED backlight module includes a bottom plate and a side plate, and a reflective film, a light guide plate, and a diffusion plate arranged on the bottom plate in sequence. The side of the light guide plate is provided with an LED light source assembly. The plate forms an accommodating space, and the reflective film, the light guide plate and the LED light source assembly are located in the accommodating sp...
