Abstract: A light-emitting device includes a multiplicity of light-emitting modules arranged on a first substrate. Each light-emitting module of the multiplicity of light-emitting modules includes a multiplicity of light-emitting components arranged on a second substrate. The second substrate is electrically connected to the first substrate, and includes a common primary lens for the multiplicity of light-emitting components.

Abstract: A light fixture comprises two cooling elements and a plurality of semiconductor lighting elements, wherein each cooling element has a central portion and a wall portion which extends away from the central portion and at least partially surrounds an interior of a cooling element. The two cooling elements are arranged opposite one another. An annular opening for exchange of air with the environment is present between the two cooling elements. The semiconductor lighting elements are arranged on the outside of the wall portion of the cooling elements. A corresponding cooling element has two or more vanes, wherein all vanes are connected to one another by means of a central connecting element. Each vane extends in an axial direction and in a circumferential direction and has a curvature in the axial direction and preferably a curvature in the circumferential direction.

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.

Abstract: In various embodiments, a light emitting diode module may include a carrier plate, at least one light emitting diode, and at least one sensor configured to register light emitted by the light emitting diode. The light emitting diode is attached to a light emitting diode installation side of the carrier plate. The sensor is installed countersunk through a hole of the carrier plate in relation to the light emitting diode installation side thereof.
