20140355264 | DIRECTIONAL LAMP WITH ADJUSTABLE BEAM SPREAD - A lamp having a lamp base and a longitudinal axis, with a first lens with more than one segment having optic elements located distal from the lamp base. Where optic elements within a segment have similar optical properties and at least two of the segments have optic elements with different optical properties. A second lens located between the distal lens and the lamp base, the second lens having a plurality of total internal reflection (TIR) lens elements each having a focal point, with a finite light source is positioned at about each of the TIR lens element focal points. At least one of the first lens or the second lens is moveable about the longitudinal axis so as to change an alignment between the optic element segments, the TIR lens elements, and the finite light sources. | 12-04-2014 |
20150030764 | PROCESS FOR RECLAIMING INORGANIC POWDERS FROM POLYMER-BASED COATING COMPOSITIONS - Processes for recovering inorganic powder materials from polymer-based coating compositions used to deposit a polymer-based coating. The process includes combining a polymer precursor, first solvent, and inorganic powder material to form a suspension, and applying the suspension to a substrate to form a layer. At least a portion of the suspension that did not adhere to the substrate is then collected. Residual portions of the first solvent and polymer precursor are at least partially removed from this portion of the suspension to yield a crude inorganic powder material comprising a residual portion of the inorganic powder and optionally a partially-cured polymer precursor, the latter of which can be removed by treating the crude inorganic powder material with a second solvent. | 01-29-2015 |
20150109758 | LED LAMP WITH ND-GLASS BULB - LED based lamps are disclosed. In an embodiment, an LED based lamp includes a concave optical diffuser, a concave neodymium-doped glass bulb, a reflector, a printed circuit board that includes a plurality of light-emitting diodes (LEDs) configured to emit light, and a heat sink body. The concave optical diffuser has a first interior volume, and the concave neodymium-doped glass bulb is positioned within the first interior volume. The neodymium-doped glass bulb defines a second interior volume, and both the reflector and the printed circuit board are positioned within the second interior volume. The reflector includes a sloped annular wall with an inner reflective surface and an outer reflective surface, and a bottom portion of the reflector is connected to the printed circuit board. The heat sink is thermally connected to the printed circuit board and to the reflector. | 04-23-2015 |
20150117021 | OMNIDIRECTIONAL LIGHT EMITTING DIODE LENS - Provided is an omnidirectional lens, having a housing having a closed end and an open end, a series of facets circumferentially arranged on the housing; and a series of concentric facets disposed on the closed end. | 04-30-2015 |
20150117026 | LAMP HAVING LENS ELEMENT FOR DISTRIBUTING LIGHT - Embodiments of a lamp that distributes light from one or more light emitting diode (LED) devices with an intensity distribution having a batwing appearance. These embodiments can comprise a lens having a lens body with different types of optics to achieve the preferred distribution. In one example, the lens body has a first section with optics that embody a plurality of prismatic facets and a second section with optics that form a convex shape, curving outward relative to the LED device. | 04-30-2015 |
20160037598 | LIGHT EMITTING DIODE RETROFIT LAMP FOR HIGH INTENSITY DISCHARGE BALLAST - Provided is an LED retrofit lamp interfacing with a high intensity discharge (HID) ballast that includes a lighting source having a plurality of light emitting diodes (LEDs), one or more heat sink components dissipating heat generated by the LEDs, and an LED driver configured to operate the LEDs. The LED retrofit lamp is disposed within an HID housing and the HID ballast is electrically connected with the LED driver, and supplies power to the LED driver for operating the LEDs. | 02-04-2016 |
20160091193 | CRYSTALLINE-GRAPHITIC-CARBON -BASED HYBRID THERMAL OPTICAL ELEMENT FOR LIGHTING APPARATUS - Provided is a lighting apparatus that includes a lighting source comprising a plurality of light emitting diodes (LEDs), one or more heat sink components dissipating heat generated by the LEDs, each heat sink component includes a first material layer, and a second material layer formed of a crystalline-graphitic-carbon-based composite comprising a crystalline-graphitic-carbon-based thermal optical element and a highly reflective optical coating combined together, and laminated with the first material layer. | 03-31-2016 |
20160097497 | LED APPARATUS EMPLOYING TUNABLE COLOR FILTERING USING MULTIPLE NEODYMIUM AND FLUORINE COMPOUNDS - The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module configured to generate a visible light such as white light, and at least one component such as an optical component comprising multiple (two or more) compounds, each containing neodymium (Nd) and at least one compound including fluorine (F) for imparting a desired color filtering effect to provide a desired light spectrum, where a color of the desired light spectrum in a color space is determined by relative amounts of the two or more compounds in the at least one component. | 04-07-2016 |
