LED heat dissipation backlight source

Abstract

The invention discloses an LED heat dissipation backlight source. The LED heat dissipation backlight source comprises a light guide plate. A fixing frame is arranged on the side face of the light guide plate. A diffusion film is arranged on the upper surface of the light guide plate. The edge of the upper surface of the diffusion film makes contact with the fixing frame. A light reflecting film is arranged on the lower surface of the light guide plate. The edge of the lower surface of the light reflecting film makes contact with the fixing frame, a light source is arranged on the side face of the light guide plate, the light source is fixedly connected with the light reflecting plate through a fixed base, the light reflecting plate is fixedly connected with the side face of the fixing frame, a heat conducting rod is arranged on the side face of the fixed base, a semiconductor refrigerating piece is arranged at the front end of the heat conducting rod, the heat conducting rod is fixedly connected with the refrigerating surface of the semiconductor refrigerating piece, and a radiator is arranged on the heating surface of the semiconductor refrigerating piece. The LED heat dissipation backlight source is simple in structure, good in sealing performance and light guiding performance and high in heat dissipation performance, the light source can be rapidly subjected to heat dissipation, all parts can be protected, therefore, the service life of all the parts is prolonged, and high practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to an LED heat dissipation backlight source. Background technique [0002] The backlight is a kind of light source located behind the liquid crystal display. Its luminous effect will directly affect the visual effect of the liquid crystal display module. The liquid crystal display itself does not emit light. It displays graphics or characters as a result of its light modulation. However, the existing The heat dissipation performance of the backlight is not good, which will easily affect the service life of the light source and cause damage to the backlight components. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an LED heat dissipation backlight with simple structure, good airtightness and light guiding performance, high heat dissipation performance, which can quickly dissip...
