A lighting device comprising a trim element, an electrical connector and at least one solid state light emitter, the lighting device weighing less than one kilogram. If current of about 12 watts (or in some cases about 15 watts, or in some cases not more than about 15 watts) is supplied to the electrical connector, the at least one solid state light emitter will illuminate so that the lighting device will emit white light of at least 500 lumens. Also, a lighting device that weighs less than one kilogram and can generate white light of at least 500 lumens using a current of not more than about 15 watts. Also, a lighting device for mounting in a recessed housing, comprising a unitary structure trim element that conducts heat away from at least one solid state light emitter and dissipates at least some of the heat outside of the recessed housing.

摘要:
A lighting device comprising a first group of solid state light emitters, with peak wavelength from 430 nm to 480 nm, and optionally a second group with dominant wavelength from 600 nm to 630 nm, and a first group of lumiphors which emit light having dominant wavelength from 555 nm to 585 nm. In some embodiments, if current is supplied to a power line, a combination of (1) light exiting the lighting device which was emitted by the first group of emitters, and (2) light exiting the lighting device which was emitted by the first group of lumiphors would, in an absence of any additional light, produce a sub-mixture of light having x, y color coordinates within an area on a 1931 CIE Chromaticity Diagram defined by points having coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), (0.36, 0.38). Also provided is a method of lighting.
摘要:
Solid state lighting (SSL) luminaires are disclosed having remote phosphors arranged to minimize heat degradation and to efficiently convert light. One embodiment of an SSL luminaire includes a light emitting diode (LED) mounted in a base. An enclosure is mounted in relation to the base so that light from the LED emits into the enclosure. A remote phosphor is mounted in the enclosure with at least some light from the LED passing into the remote phosphor where at least some of the light is absorbed and re-emitted at a different wavelength and passing through the enclosure. The remote phosphor is mounted a sufficient distance from the LED so substantially no heat from the LED passes into said conversion material, and wherein the remote phosphor has an open compound shape.

A lighting device comprising first and second groups of solid state light emitters, which emit light having peak wavelength in ranges of from 430 nm to 480 nm, and first and second groups of lumiphors which emit light having dominant wavelength in the range of from 555 nm to 585 nm. In some embodiments, if current is supplied to a power line, a combination of (1) light exiting the lighting device which was emitted by the first group of emitters, and (2) light exiting the lighting device which was emitted by the first group of lumiphors would have a correlated color temperature which differs by at least 50 K from a correlated color temperature which would be emitted by a combination of (3) light exiting the lighting device which was emitted by the second group of emitters, and (4) light exiting the lighting device which was emitted by the second group of lumiphors.
