Abstract: A stable, hermetically sealed, partially optically transparent package for use to protect optoelectronic components is provided. The package has good cooling for the installed circuit elements and is as stable in relation to temperature and UV. The package has a cap with a frame made of a nitride ceramic and a glass element. The frame has an opening and the glass element hermetically closes the opening. The glass is fused onto the nitride ceramic and is fixed in contact with the nitride ceramic of the frame.

Abstract: Lighting devices for providing a secondary light with high luminance are provided. The lighting devices include a light conversion element and a light emitting unit with a light source that emits a primary light. The light conversion element has a front side illuminated with the primary light and, in response to the primary light, to emit a secondary light from the front side. The secondary light has a larger wavelength than the primary light.

Abstract: An optoelectronic module is provided that has a carrier element, an optoelectronic element on the carrier element, a cover, and a cavity. The cover has a frame surrounding the optoelectronic element and connected to the carrier element. A glass element is on the frame lying substantially opposite the carrier element for the input and/or output of electromagnetic radiation. The cavity is inside a volume that is delimited by an inner surface of the cover and a surface of the carrier element. The optoelectronic element is arranged in the cavity and enclosed by the cover hermetically and/or in an autoclavable fashion. A filler material is in the cavity to compensate for an expansion of a volume occupied by the filler material and has a first deformable compensation volume, which is arranged adjacent to a subregion of the cover and/or of the carrier element.

Abstract: A method and device for aligning a light spot of light exiting from at least one light guide on an optical converter are provided. The device includes a light guide from which light exits and is incident on an optical converter to at least a substantial fraction, thereby forming a light spot thereon, wherein the exit surface of the fiber has an angle relative to the longitudinal axis of the fiber which is different from 0°, and the position of the light spot on the converter is aligned by adjusting the angle. A conversion module as a part of a lighting device is also provided that is operated with excitation light of a light source using a fiber-optical light guide.

Abstract: A light conversion device is provided that includes a main body and a light conversion arrangement. The main body includes heatsink and is on a back side of the light conversion arrangement. The light conversion arrangement has a front side with light conversion elements separated from one another at least regionally by a trench. The light conversion elements, when irradiated with primary light on the front side, are configured to emit secondary light having a different wavelength from the front side.
