Patent number: 9575235Abstract: A light guide element and a lighting fixture are described. The light guide element includes a light guide body, first microstructures and second microstructures. The light guide body includes a first light-emitting surface and a second light-emitting surface opposite to and parallel to each other. The first microstructures are disposed on the first light-emitting surface in rows.

Publication number: 20160195667Abstract: A direct back-lit light guide structure is applied to a light guide plate and a back-lit module. The light guide plate has a light-ejection surface and a light-inject surface opposite to the light-ejection surface. The back-lit module comprises at least one point-light source located on the light-ejection surface. The direct back-lit light guide structure comprises at least one asymmetric concave structure formed on the light-ejection surface, and each the point-light source is corresponding to one asymmetric concave structure in such a manner that the point-light source projects light directly toward the asymmetric concave structure. Each the asymmetric concave structure has a central lowest point. The point-light source is located right below the central lowest point. The direct back-lit light guide structure has advantages of better optical uniformity, higher illumination efficiency, fewer point-light sources required, lower cost, narrower side-frame and thinner light guide plate.Type: ApplicationFiled: December 28, 2015Publication date: July 7, 2016Applicant: Entire Technology Co., Ltd.Inventors: Yan Zuo Chen, Wei-Chen Lin

Patent number: 9256022Abstract: A light-directing device adapted for directing light emitted by a light source. The light-directing device includes a light-guiding plate and a directing unit that is disposed adjacent to the light-guiding plate such that a portion of the light emitted by the light source into the light-guiding plate is internally reflected by a first inclined surface thereof to exit the light-guiding plate toward an illuminating region, and another portion of the light emitted by the light source passes through the light-guiding plate, enters the directing unit and is internally reflected by a second inclined surface thereof to exit the directing unit toward the illuminating region.Type: GrantFiled: December 20, 2013Date of Patent: February 9, 2016Assignee: Radiant Opto-Electronics CorporationInventors: Wei-Chen Lin, Hui-Ching Hsueh

Patent number: 9140847Abstract: A lamp includes a frame, a light guide plate, a light source and a reflecting structure. The light guide plate is disposed on the frame and includes a light-incident surface, a first light-emitting surface and a second light-emitting surface. The second light-emitting surface is opposite to the first light-emitting surface, in which the light-incident surface connects the first light-emitting surface and the second light-emitting surface. The light source is adjacent to the light-incident surface and the light source is disposed in the frame. The reflecting structure is adjacent to the first light-emitting surface and includes at least two transparent sheets. The two transparent sheets are separated by an air gap, such that at least one light beam emitted from the first light-emitting surface is reflected back to the light guide plate and is emitted out from the second light-emitting surface.Type: GrantFiled: December 19, 2013Date of Patent: September 22, 2015Assignee: RADIANT OPTO-ELECTRONICS CORPORATIONInventors: Wei-Chen Lin, Shin-Hua Chu, Shu-Hua Yeh, Hui-Ching Hsueh

Patent number: 9121980Abstract: A light guide element and a method for manufacturing the same, and a lighting fixture are described. The light guide element includes a light guide body, a plurality of first and second microstructures corresponding to each other. The light guide body includes a first and a second light-emitting surface opposite to and parallel to each other. The first and second microstructures are respectively disposed on the first and second light-emitting surfaces by a first arrangement rule based on a first datum line and a second arrangement rule based on a second datum line. The first datum line is different from the second datum line. In a normal direction of the first light-emitting surface, each second microstructure laps over the corresponding first microstructure in part. When an incident light enters the light guide body, a first and a second mesh patterns are respectively formed on the first and second light-emitting surfaces.Type: GrantFiled: February 21, 2013Date of Patent: September 1, 2015Assignee: Radiant Opto-Electronics CorporationInventors: Wei-Chen Lin, Hui-Ching Hsueh
