Embodiment Construction

[0021] FIG. 2 shows the first embodiment of the light source system of the present invention. The light source system 10 includes a light guide plate 20 and two light sources 30 . The light guide plate 20 includes two incident surfaces 21 , an outgoing surface 22 connected to the incident surfaces 21 , and a bottom surface 24 opposite to the outgoing surface 22 . The light source 30 includes a lamp tube 31 and a reflector 32 partially surrounding the lamp tube 31 . The two light sources 30 are respectively disposed opposite to the two incident surfaces 21 of the light guide plate 20 .

[0022] Please refer to FIG. 2 and FIG. 3 together, a plurality of protrusions 23 are distributed on the bottom surface 24 of the light guide plate 20 . The plurality of protrusions 23 are used to scatter the light beams, break the total reflection condition of the light beams entering from the incident surface 21 and propagate inside the light guide plate 20 , and improve the luminance and uni...

Abstract

The invention is a kind of light source, which includes a light source and a light board, the light board comprises at least an entrance face receiving beams and a bottom face opposite to the exit face, there are several bulges on the bottom, the scattering facets forms a curved face, which is used to gather the beam scattered by the bulge, the bottom of the light board and the scattering face have a layer of reflecting film, the exit face is a coarse face with controllable coarse rate.

Description

【Technical field】 [0001] The invention relates to a light guide plate with high luminance and uniform light output and a light source system using the light guide plate. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display devices are widely used in modern information equipment such as notebook computers, mobile phones, and personal digital assistants. Since the liquid crystal itself does not have luminous properties, it is necessary to provide a light source system for it to realize the display function. [0003] The light source system in the prior art includes a light source and a light guide plate. The light source is arranged relative to the light incident surface of the light guide plate. The light guide plate guides the transmission direction of the light beam emitted from the light source, and converts the line light source or point light source into a surface light source to emit. The bottom...
