Abstract: A lighting device including a blue solid state emitter, at least one yellow-green or green lumiphoric material, and at least one red or red-orange solid state emitter can simultaneously provide high color fidelity (e.g., high CRI Ra), high color saturation (e.g., high Qg), and high efficiency (e.g., lumens per watt). A subcombination of blue and yellow-green emissions is provided within one or more specified regions of a 1931 CIE chromaticity diagram. By providing sufficient green content, increased saturation can be active with relatively a short wavelength red or red-orange source while maintaining high color fidelity and efficacy. A mixture of green and yellow lumiphoric materials may be provided.

Abstract: An inflatable display with dynamic lighting effect has an inflatable body, an air pump inflating the inflatable body, and a lighting assembly mounted inside the inflatable body for providing dynamic lighting variations. The lighting assembly has a light housing, a power supply, a lighting module, and a refracting module mounted in the light housing. The lighting module and the refracting module rotate relative to each other. As light beams emitted from the lighting module pass through the refracting module, the light beams are mixed and refracted. With relative rotation of the lighting module and the refracting module, the light beams can project outwards to further penetrate through the inflatable body at different angles covering a large area to form the dynamic lighting variations and to exhibit the dynamic lighting effect.
Abstract: A flameless candle molded into a jar is described. The jar is designed with an open bottom and is tooled for engagement with an electronic insert having batteries, control circuitry and at least one LED light. A candle is then formed in the jar with the electronic insert by molding a candle shell along the sidewalls of the jar. The candle shell is formed such that the sidewalls extend above the LED light of the electronic insert to allow the LED light to illuminate at a position below the sidewalls. The wax or waxen shell is formed only along the sidewalls, creating a hollow region above the electronic insert. Once the wax on the sidewalls sets, wax is then poured in the hollow regions above the electronic insert to a position just below or above the LED light.
Abstract: A light emitting assembly comprising a solid state device coupleable with a power supply constructed and arranged to power the solid state device to emit from the solid state device a first, relatively shorter wavelength radiation, and a down-converting luminophoric medium arranged in receiving relationship to said first, relatively shorter wavelength radiation, and which in exposure to said first, relatively shorter wavelength radiation, is excited to responsively emit second, relatively longer wavelength radiation. In a specific embodiment, monochromatic blue or UV light output from a light-emitting diode is down-converted to white light by packaging the diode with fluorescent organic and/or inorganic fluorescers and phosphors in a polymeric matrix.
