Abstract: A booster optic is provided in an LED light assembly that includes a primary reflective surface to redirect light towards a desired location to form an illuminance pattern that when combined with a first illuminance pattern, which is formed by only the primary reflector, provides a combined illuminance pattern having a more uniform illuminance characteristic as compared to not having the booster optic.

Abstract: An LED device including an LED chip and a lens positioned apart from the chip and coated with a uniform thickness layer of fluorescent phosphor for converting at least some of the radiation emitted by the chip into visible light. Positioning the phosphor layer away from the LED improves the efficiency of the device and produces more consistent color rendition. The surface area of the lens is preferably at least ten times the surface area of the LED chip. For increased efficiency, the reflector and submount can also be coated with phosphor to further reduce internal absorption.

Abstract: A heat dissipating lamp is provided. The lamp includes a reflector, a lens cover, a support structure interposed between the reflector and the lens cover, and an LED mounted to the support structure. The lens cover includes a portion adjacent a peripheral edge of the reflector. The support structure includes a bridge.

Abstract: An electronic flash apparatus for a camera includes a housing, a white light LED (light emitting diode) mounted in the housing, and a cover lens mounted on an open end of the housing. A DC power supply and control circuit provide power to the LED via lead wires. The activation of the LED may be synchronized with the taking of a picture by an associated camera. The LED allows for an improved flash by reducing the manufacturing cost and the number of parts needed for a conventional flash using a discharge tube.
