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 |
20100008628 | SLIM WAVEGUIDE COUPLING APPARATUS AND METHOD - In various embodiments, an illumination structure includes a discrete light source disposed proximate a bottom surface of a waveguide. A top mirror may be disposed above the discrete light source to convert modes of light emitted from the discrete light source into trapped modes, thereby increasing the coupling efficiency of the illumination structure. | 01-14-2010 |
20100091293 | SEMITRANSPARENT INTEGRATED OPTIC MIRROR - An optical device is disclosed. The device comprises a waveguide formed within a substrate; and at least one semitransparent mirror structure formed within the waveguide and being designed and constructed to partially reflect light propagating in the waveguide such that a portion of the light is emitted through the surface of the waveguide. The semitransparent mirror structure(s) is capable of reflecting light while substantially preserving the shape of the light profile in the waveguide. | 04-15-2010 |
20100208469 | 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, by reflecting, through the gaps between adjacent light-guide elements, light directed through the bottom surfaces of the elements. | 08-19-2010 |
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 |
20100220484 | SLIM WAVEGUIDE COUPLING APPARATUS AND METHOD - In various embodiments, an illumination structure includes a discrete light source disposed proximate a bottom surface of a waveguide and below a depression in a top surface thereof. A top mirror may be disposed above the discrete light source to convert modes of light emitted from the discrete light source into trapped modes, thereby increasing the coupling efficiency of the illumination structure. | 09-02-2010 |
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 |
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 |
20130033164 | PLANAR REMOTE PHOSPHOR ILLUMINATION APPARATUS - In various embodiments, reduced phosphor utilization and improved off-state appearance are facilitated in an illumination apparatus via incorporation of segmented phosphor and/or reflector layers. | 02-07-2013 |
20130058610 | SLIM WAVEGUIDE COUPLING APPARATUS AND METHOD - In various embodiments, an illumination structure includes a discrete light source disposed proximate a bottom surface of a waveguide and below a depression in a top surface thereof. A top mirror may be disposed above the discrete light source to convert modes of light emitted from the discrete light source into trapped modes, thereby increasing the coupling efficiency of the illumination structure. | 03-07-2013 |
20130121001 | ILLUMINATION APPARATUS CONFINING LIGHT BY TOTAL INTERNAL REFLECTION AND METHODS OF FORMING THE SAME - In various embodiments, an illumination apparatus includes an air gap between a sub-assembly and a waveguide attached thereto at a plurality of discrete attachment points, as well as a bare-die light-emitting diode encapsulated by the waveguide. | 05-16-2013 |
20140119025 | ILLUMINATION APPARATUS CONFINING LIGHT BY TOTAL INTERNAL REFLECTION AND METHODS OF FORMING THE SAME - In various embodiments, an illumination apparatus includes an air gap between a sub-assembly and a waveguide attached thereto at a plurality of discrete attachment points, as well as a bare-die light-emitting diode encapsulated by the waveguide. | 05-01-2014 |
20150023060 | ILLUMINATION APPARATUS CONFINING LIGHT BY TOTAL INTERNAL REFLECTION AND METHODS OF FORMING THE SAME - In various embodiments, an illumination apparatus includes an air gap between a sub-assembly and a waveguide attached thereto at a plurality of discrete attachment points, as well as a bare-die light-emitting diode encapsulated by the waveguide. | 01-22-2015 |
20150049507 | SLIM WAVEGUIDE COUPLING APPARATUS AND METHOD - In various embodiments, an illumination structure includes a discrete light source disposed proximate a bottom surface of a waveguide and below a depression in a top surface thereof.
