Problems solved by technology

However, only relying on the optical surface design of the light guide to distribute the light beam still has the defect of uneven distribution of the light beam (that is, poor light uniformity), which causes obvious bright lines to occur when this type of light source device is close to the wall.
For users who have long been accustomed to tungsten-based lighting devices, the visual effect is not good

Abstract

A light guiding apparatus including a first light guide and a second light guide is provided. The first light guide includes a first end surface thereon, a second end surface and a side surface thereon, wherein the first end surface includes a first light incident surface, the second end surface includes a first light emitting surface, 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 light incident surface and a second light emitting surface connecting to the second light incident surface, wherein at least a portion of region of the second light emitting surface is a roughened surface. The second light incident surface or the first light emitting surface is a roughened surface, and a medium is between the second light incident surface and the first light emitting surface, wherein the medium has a refractive index smaller than that of the first light guide and the second light guide.

Description

technical field [0001] The present invention relates to a light source device, and in particular to a light guide device and a light source device. Background technique [0002] The light source device in the existing crystal lamp is designed according to the tungsten light source located in the center of the lampshade. However, the light-emitting mechanism based on tungsten filament is very power-hungry, and has a short service life and high wear rate. [0003] In recent years, with the good development of the light emitting diode (light emitting diode, LED for short) light source, another option is provided for the light source device. To achieve power saving and other features. In an existing light source device in a crystal lamp, a light emitting diode is arranged at one end of a cylindrical light guide, and the cylindrical light guide is used to guide the light to the other end, so as to achieve the effect of light transmission. [0004] It should be noted that, in t...
