Box-type light source mold train and back light system

Abstract

This invention relates to one case light source module set and aphototropism system, which comprises at least one light source and one shell, wherein, the shell comprises one bottom board and multiple side walls connected to the bottom board; the multiple side walls and the bottom board form one chamber with one open hole; the light source is set in one inner side of the shell; the light source side wall is set with multiple dissipation fins and the bottom board has one reflection surface facing to light source and open hole.

Description

【Technical field】 [0001] The present invention relates to a box-type light source module applied to a liquid crystal display and a backlight system using the box-type light source module. 【Background technique】 [0002] In recent years, liquid crystal displays have been widely used due to their lightness, thinness, smallness and low power consumption. Since the liquid crystal itself does not have light-emitting properties, a backlight system is required to provide a backlight source for it to realize the display function of the liquid crystal. [0003] The backlight system is divided into two types: side light type and direct type. For small and medium-sized liquid crystal displays, edge-lit backlight systems have the advantages of lightness, thinness, and low power consumption. However, with the development of science and technology, the demand for large-size LCDs is increasing day by day, and edge-lit backlight systems cannot meet the brightness requirements of large-siz...

Problems solved by technology

[0006] The backlight system 10 increases heat dissipation efficiency through the heat dissipation plate 140 arranged on the back of the reflector 130, but the backlight system 10 has the following disadvantages: the light source 110, the reflector 130 and the heat dissipation plate 140 are all arranged at the bottom of the housing 150, which is unavoidable. Because the heat sink 140 and the light source 110 occupy space, the thickness of the backlight system 10 increases; the housing 150 covers the reflector 130 and the heat sink 140, and a certain space interval needs to be set between the housing 150 and the heat sink 140 so that Increasing the heat dissipation effect due to air convection will inevitably increase the thickness of the backlight system, and the coating of the casing 150 is not conducive to heat dissipation to the outside world, reducing the heat dissipation efficiency of the module
