INTEGRATED FRONT LIGHT SOLUTION
First Claim
1. An integrated illumination apparatus comprising:
- a light injection portion having a first end for receiving light from a light source, said light injection portion comprising material that supports propagation of said light along the length of the light injection portion towards a second opposite end;
turning microstructure disposed on a first side of the light injection portion, the turning microstructure configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light towards a second opposite side of the light injection portion;
a slit disposed along the length of the light injection portion, the slit forming an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein, said optical interface further transmitting light turned by said turning microstructure;
a light distribution portion disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit; and
at least one bridge disposed between light injection portion and the light distribution portion and mechanically connecting the light injection portion to the light distribution portion.

Abstract
An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure. A light distribution portion is disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit. At least one bridge is disposed between light injection portion and the light distribution portion. The bridge mechanically connects the light injection portion to the light distribution portion.

45. An illumination apparatus comprising:
-
means for injecting light having means for receiving light from a means for emitting light, said light injecting means comprising means for supporting propagation of said light along the length of the light injecting means towards an end of said light injecting means; means for turning light disposed on a first side of the light injecting means, the light turning means configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light towards a second opposite side of the light injecting means; means for forming a means for providing total internal reflection for light propagating along the length of the light injecting means to be guided therein, said total internal reflection means disposed along the length of the light injecting means on the second opposite side of the light injecting means, said total internal reflection providing means further transmitting light turned by said light turning means; means for distributing light disposed with respect to the forming means to receive the light from said light turning means and transmitted out of the second side of the light injecting means and through said forming means; and means for mechanically connecting disposed between and mechanically connecting the light injecting means and the light distribution means. - View Dependent Claims (46)
