Embodiment Construction

[0072]The light source module of the present invention can be applied to lamps or displays, and can provide uniform light. Specifically, the light source module can be used as a lighting fixture such as a ceiling lamp or a desk lamp, or as an auxiliary lighting fixture such as a decorative art lamp or a warning lamp with a warning function. In addition, the light source module can also be used as a light source for a backlight module in a liquid crystal display.

[0073] In one embodiment of the present invention, the light source module includes N light-emitting elements and a light guide device, and the light guide device includes N linear light splitters and N+1 light guide plates, where N is a natural number, representing the quantity, Therefore, the number of light-emitting elements can be at least one, and the number of light guide plates can be at least two. It can be seen that the number of light-emitting elements and linear beam splitters is the same, and the number ...

Abstract

The invention discloses a light module and a light guide device thereof. The light guide device includes N+1 light guide plates and N linear plane splitters. Each light guide plate include a light outlet face, a light guiding face and a reflection face. The volume of the light guide device is defined by the light outlet face opposite to the light guiding face. The light guiding face has a plurality of first microstructures for diverting the light. The reflection face extends from the light outlet face toward a splitting portion. Each linear plane splitter has a first and a second splitting portion. The first and second splitting portions of the ith linear plane splitter connects the light guiding face and the reflection face of the (j-1)th and jth light guide plates. The i and j satisfy 1<=i<=N and 2<=j<=N+1.

Description

technical field [0001] The invention relates to a light-emitting device and the optical elements it includes, and in particular to a light source module and a light guide device thereof. Background technique [0002] Today's high-brightness light-emitting elements, especially light-emitting diodes (Light-Emitting Diodes, LEDs), usually have relatively high directivity (directivity), so that such light-emitting elements emit light in a concentrated manner. Therefore, when the above-mentioned light-emitting element (such as a light-emitting diode) emits light, the light-emitting element will produce obvious bright spots, and it is difficult to produce a soft or uniform lighting effect. [0003] Therefore, in current lighting or displays (such as liquid crystal displays, Liquid Crystal Displays, LCDs) using high-brightness light-emitting elements, a diffuser is usually installed to even out the light emitted by the high-brightness light-emitting elements.
