Embodiment Construction

[0026] figure 1 It is a schematic diagram of applying the light guide device of the first embodiment of the present invention to a light source device. Please refer to figure 1 , the light source module 10 includes a light guide device 100 , a light source 20 and a light guide plate 30 . The light guide plate 30 and the light source 20 are respectively located on different sides of the light guide device 100 , and the light source 20 is, for example, a point light source, such as a light emitting diode light source. The light emitted by the light source 20 can be converted into a linear light source by the light guide device 100 to be incident on the light guide plate 30 , and the light guide plate 30 can further convert the linear light source into a surface light source for utilization. In an embodiment, when the light source module 10 is required to provide a linear light source, the light guide plate 30 may be selectively not configured.

Abstract

The invention provides a light guide device and a light source module. The light guide device comprises a light guide post. The light guide post has an incident surface, an emergent surface, two connecting surfaces and a bottom surface, wherein the incident surface is positioned on the end part of the light guide post; the emergent surface, the connecting surfaces and the bottom surface are connected to the incident surface respectively; the emergent surface and the bottom surface are positioned on the two opposite sides of each connecting surface, and are opposite to each other to define an emergent direction which points to the emergent surface from the bottom surface; the area of the emergent surface is larger than that of the bottom surface; and the variation trend of the sectional area of the light guide post along the emergent direction comprises gradual increasing, and the sectional area is parallel to the emergent surface or the bottom surface.

Description

technical field [0001] The invention relates to a light guide device and a light source module, in particular to a light guide device for converting a point light source into a linear light source and a light source module with the light guide device. Background technique [0002] For a general liquid crystal display, its display medium is a non-self-luminous liquid crystal molecule. Therefore, the liquid crystal display is mainly composed of a liquid crystal panel and a backlight module, wherein the backlight module is used to provide the surface light source required by the liquid crystal panel, so that the liquid crystal display can achieve the display effect. Light emitting diodes with small size, low energy consumption, good light directivity and high luminous efficiency are often used as light sources in backlight modules. However, the point distribution of light emitting diode light sources may cause uneven distribution of light sources, and the use of multiple light...
