Patent ID: 8761556

Claim:
A light guide device having multi channels guides a plurality of incident collimated beams through each channel, the light guide device comprising: a permeable body ( 10 ′) for permeating lights; a channel optical concentrating unit ( 20 ′) formed on said permeable body ( 10 ′); a plurality of first horizontal reflection units ( 41 h ′) being arranged with constant intervals on a horizontal plane for totally reflecting incident collimated lights from each of optic module units ( 21 ) parallel to x-axis direction; and a plurality of optical channel modules ( 40 ′) for guiding the incident collimated lights ( 11 b ) from each of the optic module units ( 21 ), so that discharged lights ( 11 c ) travel parallel to the x-axis direction on the horizontal plane; wherein each of the plurality of first horizontal reflection units ( 41 h ′) is lined-up to the corresponded optic module unit ( 21 ) on a respective vertical plane to form its own unique channel, so that the unique channel does not interrupt with the other unique channels.
