Patent number: 8371735Abstract: Provided is a multi-layer light guide apparatus. Various optical paths are formed as a light source emits light into the apparatus. Main structure of the apparatus includes a body and a micro-structured layer. The body has a first layer with first refractive index (n1) and a second layer with second refractive index (n2). The first layer has a first critical angle (?C1). An interface critical angle (?C12) is formed between the associated first layer and second layer. The light then outputs as the light propagates through the layers. The micro-structured layer is formed on a side of the body. It features: n1<n2;0<|?C12??C1|?35°; A third layer with a third index of refraction (n3) is further included. A second interface critical angle (?C23) is formed between the second layer and the third layer. It features: n1<n2<n3;?C23>?C12;0<|?C12??C1|?35°.Type: GrantFiled: September 3, 2010Date of Patent: February 12, 2013Assignee: Entire Technology Co., Ltd.Inventors: Yan Zuo Chen, Chung-Hung Chien, Wen-Feng Cheng, Hao-Xiang Lin

Publication number: 20110058124Abstract: A composite optical device including pluralities of optical elements, pluralities of lighting devices, an emitting surface and a reflecting surface is provided. Each optical element including two first laterals, two second laterals, a third lateral and fourth lateral. The third lateral and the fourth lateral have a space respectively. The third lateral is adjacent to the fourth lateral of another optical element. Each lighting device is disposed inside the space. Whereby the third lateral and fourth lateral may receive the light energy of the lighting device and then the optical element delivers the light beam to the first lateral, the second lateral, the third lateral and the fourth lateral by means of the reflection of the reflecting surface. Finally, the light beam is output through the emitting surface.Type: ApplicationFiled: September 9, 2009Publication date: March 10, 2011Applicant: Entire Technology Co., Ltd.Inventors: Chung-Hung CHIEN, Wen-Feng CHENG
