Abstract: An optical converter assembly includes a housing, a securing mechanism, and a light converter. The housing defines a first opening that receives part of a light-emitting portion of a dental curing light when the housing is selectively secured relative to the light-emitting portion of the dental curing light. The securing mechanism selectively retains the housing relative to the light-emitting portion. The light converter is comprised of a phosphor material and secured relative to the housing such that input light having a first set of wavelengths and radiant power emitted by the dental curing light is received. The light converter converts the input light to an output light having a second set of wavelengths and radiant power and to emit the output light. The input light includes a blue light and an ultraviolet light that polymerizes a dental material. The output light may be a white light.

Abstract: A light-emitting apparatus includes an excitation light source that emits first light; a light-emitting device on an optical path of the first light, the light-emitting device emitting second light having a wavelength in air; and a first converging lens on an optical path of the second light. The light-emitting device comprises: a photoluminescent layer that emits the second light by being excited by the first light; and a light-transmissive layer on the photoluminescent layer. At least one of the photoluminescent layer and the light-transmissive layer has a surface structure comprising projections or recesses arranged perpendicular to a thickness direction of the photoluminescent layer. At least one of the photoluminescent layer and the light-transmissive layer has a light emitting surface perpendicular to the thickness direction, the second light emitted from the light emitting surface. The surface structure limits the directional angle of the second light emittied from the light emitting surface.
