Patent application number | Description | Published |
20090161361 | DISCRETE LIGHTING ELEMENTS AND PLANAR ASSEMBLY THEREOF - In one aspect, a light-emitting surface includes a plurality of discrete, substantially flat light-emitting illumination devices arranged in a tiled configuration. Each device has a light-emitting area and an unilluminated area, the light-emitting area of a first device occluding at least a portion of the unilluminated area of a second, adjacent device. | 06-25-2009 |
20090161369 | WAVEGUIDE SHEET AND METHODS FOR MANUFACTURING THE SAME - In one aspect, an illumination structure includes a substantially non-fiber waveguide, which itself includes a discrete in-coupling region for receiving light, a discrete propagation region for propagating light, and a discrete out-coupling region for emitting light. | 06-25-2009 |
20090162015 | STITCHES ELIMINATION STRUCTURE AND METHOD TO PROVIDE THE SAME - In one aspect, a planar illumination area includes two light-guide elements, each with an out-coupling region. At least a portion of each out-coupling region overlaps with at least a portion of the other. The overlapping region emits a substantially uniform light output power. | 06-25-2009 |
20090290380 | WAVEGUIDE-BASED PACKAGING STRUCTURES AND METHODS FOR DISCRETE LIGHTING ELEMENTS - In one aspect, an illumination source includes a socket formed by the union of a sub-assembly platform and a light-guide element, and a discrete light source received in the socket. In another aspect, the light-guide element includes a concentration region proximate an in-coupling region opposite an out-coupling region, the concentration region directing multidirectional light from the in-coupling region toward the out-coupling region. | 11-26-2009 |
20100208470 | OVERLAPPING ILLUMINATION SURFACES WITH REDUCED LINEAR ARTIFACTS - Illumination surfaces according to the present invention eliminate or at least reduce linear “stitch” artifacts at edges between tiled illumination devices. As a result, light of substantially uniform intensity is emitted across the entire illumination system. This is achieved, in various embodiments, overlapping the illumination surfaces of adjacent light-guide elements. | 08-19-2010 |
20100272392 | ELIMINATION OF STITCH ARTIFACTS IN A PLANAR ILLUMINATION AREA - In one aspect, a planar illumination area includes two light-guide elements, each with an out-coupling region. At least a portion of each out-coupling region overlaps with at least a portion of the other. The overlapping region emits a substantially uniform light output power. | 10-28-2010 |
20100315817 | LOW-PROFILE ILLUMINATION DEVICE - An illumination system in accordance with an embodiment hereof includes a first substantially flat waveguide for propagating and emitting light. The first waveguide may include a plurality of optical elements increasing in density from an edge to the center of the first waveguide. Light enters the first waveguide at the edge, and light is emitted from the top surface of the first waveguide. The intensity of the emitted light is substantially uniform over the top surface. | 12-16-2010 |
20110013415 | DISCRETE LIGHT GUIDE-BASED PLANAR ILLUMINATION AREA - In one aspect, a planar illumination area includes two light-guide elements, each with an out-coupling region. At least a portion of each out-coupling region overlaps with at least a portion of the other. The overlapping region emits a substantially uniform light output power. | 01-20-2011 |
20130216964 | CANDELABRUM OF HANGING CANDLES - A candelabrum includes a frame assembly, a pair of anchor beams, and at least one candle support. The frame assembly includes a first frame member, a second frame member, and at least one cross member. The first frame member is rigidly coupled to the second frame member via the at least one cross member. The pair of anchor beams is coupled to the frame assembly. The at least one candle support is pivotally coupled to the pair of anchor beams. The at least one candle support is configured to receive a candle therein. | 08-22-2013 |
