20140092629 | LIGHT GUIDE ELEMENT AND METHOD FOR MANUFACTURING THE SAME, AND LIGHTING FIXTURE - 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. | 04-03-2014 |
20140328067 | LIGHT GUIDE ELEMENT FOR CONTROLLING LIGHT SHAPE - A light guide element for controlling light shape includes a light-incident surface, a light-emitting surface, a first reflecting surface, and a second reflecting surface. The light-incident surface includes a first outer peripheral edge and a first inner peripheral edge. The light-emitting surface includes a second outer peripheral edge and a second inner peripheral edge. The first reflecting surface is constructed by a first profile curve, and connects the first and the second outer peripheral edge. The first profile curve is a connecting line of two points respectively on the first outer peripheral edge and the second outer peripheral edge. The second reflecting surface is constructed by a second profile curve, and connects the first and the second inner peripheral edge. The second profile curve is a connecting line of two points respectively on the first inner peripheral edge and the second inner peripheral edge. | 11-06-2014 |
20140369069 | OPTICAL MODULE AND LAMP - 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. | 12-18-2014 |
20150177442 | LIGHT GUIDE ELEMENT AND LIGHTING FIXTURE - 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. The second microstructures are respectively corresponding to the first microstructures and are disposed on the second light-emitting surface. In each of the rows, each of the first microstructures laps over the corresponding second microstructure in part in a normal direction of the first light-emitting surface. Overlapping ratio of the first microstructures and the corresponding second microstructures become greater from one end of one of the rows to the other end of the one of the rows. | 06-25-2015 |
