The shapes of the reflectors are selected to cooperatively produce a highly collimated light beam. Color mixing may be improved by providing a plurality of facets on the reflective surfaces of at least one of the primary reflector or the secondary reflector. | 02-18-2010 |
| 20100118510 | HIGH COLOR RENDERING INDEX WHITE LED LIGHT SYSTEM USING MULTI-WAVELENGTH PUMP SOURCES AND MIXED PHOSPHORS - The present invention relates to an LED lighting system producing light having improved Color Rendering Index (CRI). The system includes a plurality of LEDs wherein the LEDs have at least a first and second characteristic wavelength, and a mixed phosphor layer overlying at least one of a portion of the plurality of LEDs, the phosphor layer absorbing at least a portion of the LED-emitted light and producing phosphor-emitted light, wherein the phosphors includes a third characteristic wavelength and a fourth characteristic wavelength, wherein the third characteristic wavelength and fourth characteristic wavelength are not the same. | 05-13-2010 |
| 20100238645 | MULTI-CAVITY LED ARRAY RGB COLLIMATION OPTIC - This invention relates to optical devices. More specifically, the present invention relates to a collimated optical light source assembly that produces a uniform white light. Specifically, light from a multi-cavity RGB LED array is dispersed in a reflecting cavity having a Lambertian texture on the interior surface. The light is then emitted though a lenslet array and a cone lens which together further disperses the light emitted by the individual LEDs. The dispersed light is then collimated by a reflector. | 09-23-2010 |
| 20110051394 | WARM WHITE LIGHTING DEVICE - The present invention relates to warm white light engines including combinations of blue, cyan, and red, red-orange, or amber emitters and one or more phosphors that produce a white light pleasing to the human eye through the use of improved color uniformity and improved collimation of light. Specifically, a micro-lenslet array having an optimized surface is used to disperse light from the light emitter; an innercollimation lens having an optimized cross-sectional shape and micro-ridges is used to disperse light; a TIR reflector having an optimized cross-sectional shape and micro-ridges is used to disperse and redistribute phase as well as provide collimation; and a final micro-lenslet layer includes optimized lenslet design placement and randomization factor to homogenize light to produce a uniform warm white light. | 03-03-2011 |

| 20090212698 | Solid-state luminescent filament lamps - Traditional incandescent and halogen lamps produce a high CRI warm white light with indirect emission patterns at the cost of poor energy efficiency. This new advancement in solid-state lighting enables the production of a new solid-state filament wherein the tungsten filament is replaced with an array of high efficiency LED emitters which combine through an equiangular spiral, or t-spline/TNURCC lightpipe network to produce a single homogeneous blue light source which then pumps a luminescent filament comprised of a phosphor loaded silicone, phosphor loaded polymer, a lanthanide doped fluoro-phosphate glass, glass ceramic tape, quantum dot filled composite, or super-continuum spectrum producing photonic crystalline structure. | 08-27-2009 |

| 20090237399 | Computer Aided Design method for enhancement of local refinement trough T-Splines - One embodiment of the present technology provides a the method comprises the steps of: Converting B-spline networks to T-splines, Converting NURBS into T-spline surfaces, Adding control points to local regions, Scaling or optimizing weights across the mesh, and merging between NURBS and T-spline surfaces. The technology overcame some of the issues with implementing simultaneous multiple surface design methodology when dealing with groups of lenses and reflectors, by improving seed patch junction continuity, elimination of ripples and holes, and precisely adding control points where required. In at least one embodiment of the technology, the t-splines topology allowed for refined control over the optical surface. Control points were reduced by conversion of a NURBS into a T-spline. T-splines were used to produce new loft lenses which were further refined and merged to spline patches. In another embodiment of the present technology, the T-spline loft lens network was subsequently optimized through reverse raytracing, bi-directional raytracing, flow-line, optical path, or flux tube approach. | 09-24-2009 |

| 20090192550 | BONE PLATING SYSTEM - A bone plating system includes a plate member and a first bone screw. The plate member defines a longitudinal axis and has a top surface and a bottom surface. The plate member further defines an elongated hole extending between the top surface and the bottom surface with a width in a direction generally perpendicular to the elongated axis and a length with a greater dimension in a direction generally parallel to the elongated axis. The elongated hole is defined by a sidewall having a spherical cross section in the direction generally perpendicular to the elongated axis. The sidewall has a threading. The first bone screw has a threaded and spherical head for threadably engaging the elongated hole. The threading extends completely around the sidewall of the elongated hole such that the first bone screw may threadably engage the elongated hole anywhere along the length. | 07-30-2009 |

| 20090018663 | INTERVERTEBRAL IMPLANT AND ASSOCIATED METHOD - An intervertebral implant and associated method. The intervertebral implant can include a first component having a first articulating surface and a first bone engagement surface for engaging a first vertebra, and a second component having a second articulating surface and a second bone engagement surface for engaging a second vertebra adjacent to the first vertebra. The first and second articulating surfaces can articulate with each other for substantially replicating a natural spinal movement. The first and second bone engagement surfaces can define an outer surface substantially shaped as an envelope of two intersecting cylinders. In one aspect, the first and second articulating surfaces can have substantially equal radii of curvature in a coronal plane and different radii of curvature in a sagittal plane. | 01-15-2009 |

| 20110148647 | Manhole Security Device and Methods Thereof - A security device for detecting the position of a manhole cover includes a pinger device, such as an acoustic pinger, that transmits a signal in the direction of the expected position of the manhole cover. The device takes energy samples to determine if the signal has been reflected back by the manhole cover. If the device determines the signal has not been reflected, it determines that the manhole cover has been moved from the expected position. In response, the device captures an image of an area around the expected position of the manhole cover. In addition, the device can notify a remote security station via a network that the manhole cover has been moved. | 06-23-2011 |
