LIGHT GUIDING APPARATUS AND LIGHT SOURCE DEVICE INCLUDING THE SAME
First Claim
1. A light guiding apparatus, comprising:
- a first light guide comprising a first end-surface, a second end-surface and a side-surface, wherein the first end-surface comprises a first light incident surface thereon, the second end-surface comprises a first light emitting surface thereon, and the side-surface is located between the first end-surface and the second end-surface of the first light guide; and
a second light guide having a second incident surface and a second light emitting surface connecting the second incident surface, wherein at least a partial region of the second light emitting surface is a roughened surface, the second incident surface or the first light emitting surface is a roughened surface, the second incident surface is corresponding to the first light emitting surface, and a medium with a refractive index less than the refractive indexes of the first light guide and the second light guide is located between the second incident surface and the first light emitting surface.

Abstract
A light guiding apparatus includes a light guiding apparatus and a second light guide. The first light guide includes a first end-surface, a second end-surface and a side-surface, in which the first end-surface includes a first light incident surface thereon, the second end-surface includes a first light emitting surface thereon, and the side-surface is located between the first end-surface and the second end-surface of the first light guide. The second light guide has a second incident surface and a second light emitting surface connecting the second incident surface, in which at least a partial region of the second light emitting surface is a roughened surface, the second incident surface or the first light emitting surface is a roughened surface, and the second incident surface is corresponding to the first light emitting surface.
