    摘要： Methods for producing wavelength converters are described. The methods include sintering a mixture consisting essentially of first particles and second particles to form a sintered article. In embodiments the first particles consist essentially of particles of β-SiAlON or precursors thereof, and the second particles consist essentially one or more sintering aids or precursors thereof. In embodiments the sintered article has a density that is greater than or equal to about 90% of a theoretical bulk density of the mixture, and is configured to convert primary light incident thereon to secondary light, wherein the secondary light exhibits a peak with a full width half maximum of greater than 0 to about 60 nanometers (nm) within a wavelength range of about 495 nm to about 600 nm.

    摘要： The present disclosure generally provides an LED lamp comprising a substrate, an LED light source in optical communication with the substrate, a diffusive coating applied to the substrate, and a luminescent coating disposed at least partially on the diffusive coating. The luminescent coating is between the LED light source and the diffusive coating. The luminescent coating has a composition selected to achieve a particular color temperature according to a characteristic of the LED light source. The present disclosure also generally provides a method of producing an LED lamp, comprising selecting a composition of a luminescent coating to achieve a particular color temperature according to a characteristic of an LED light source of the LED lamp, and coating a substrate in optical communication with the LED light source with a diffusive coating and the luminescent coating having the selected composition.

    摘要： The invention provides a color conversion arrangement, a lighting unit, a solid state light emitter package, a luminaire and a specific use of a graphene layer. A color conversion arrangement (140) with the first aspect comprises a first luminescent layer (110), a supporting layer (106) and a first graphene layer (108). The color conversion arrangement (140) is for converting light of a first color to light of another color. The first luminescent layer (110) comprises a first luminescent material which absorbs a portion of light of a first spectral distribution comprising the first color and converts at least a portion of the absorbed light towards light of a second spectral distribution. The supporting layer (106) supports the luminescent layer (110). The first graphene layer (108) thermally conducts heat in a lateral direction such that temperature differences in the color conversion arrangement (140) are reduced. Different arrangements of the layers of the color conversion arrangement (140) are provided.

    摘要： A vehicle switch is provided herein. The vehicle switch includes a housing including an output window. A first light source and a second light source are disposed within the housing. The first light source emits excitation light of a first wavelength. The second light source emits excitation light of a second wavelength. A proximity switch assembly is positioned within the housing and is configured to control a vehicle feature. A first luminescent structure is disposed rearwardly of the output window and luminesces in response to excitation light of the first wavelength when the feature is in a first state. A second luminescent structure is disposed rearwardly of the output window and is configured to luminesce in response to excitation light of the second wavelength when the feature is in a second state.
