Abstract: Techniques for bonding a luminescent material to a thermally conductive substrate using a low temperature glass to provide a wavelength converter system are provided. A dichroic coating is deposited on a thermally conductive substrate. The dichroic coating includes alternating layers of a first material having a first refractive index and a second material having a second refractive index which is greater than the first refractive index. A buffer layer is deposited on the dichroic coating. A wavelength converter is bonded to the buffer layer by a layer of low temperature glass. In some embodiments, the wavelength converter includes a phosphor for converting a primary light from an excitation source into a secondary light.

Abstract: Various embodiments relate to a lighting device with an optoelectronic light source, an optical body downstream thereof for distributing the light, and a diffuser downstream of the latter, onto the light entry surface of which the light emitted by the optical body falls and the light exit surface of which represents a light emission surface of the lighting device. To homogenize the luminous intensity on the light exit surface, in addition to distributing the light with the optical body, the diffuser is not provided to be uniformly scattering to such an extent that light falling thereon in a central region is scattered more intensely than light falling thereon in an edge region.
