Abstract: The invention provides an illumination device comprising a pump light source and a phosphor wheel. The phosphor wheel comprises at least two segmented phosphor layers. The front surfaces of the phosphor layers do not form a common plane, but instead a kind of relief in which the surfaces of the phosphor layers extend in different imaginary planes. When the phosphor wheel rotates through a beam waist of the pump. light, in this way the size of the pump light spot and therefore also the power density distribution of the pump light on the respective phosphor layer are adapted.

Abstract: Disclosed herein is a cooling device, comprising a cooling plate and a cooling cap, for cooling a heat source, mounted to an outer interface surface of the cooling plate, by means of a cooling fluid. Several spiral-shaped fins are integrated into the cooling plate to form a structure in the shape of a multi-spiral. The fins are arranged next to each other in a mutual distance to form spiral-shaped flow channels for a cooling fluid. An inlet for inflowing the cooling fluid at the center of the multi-spiral fins structure is integrated into the cooling cap. The cooling cap is configured and arranged on the cooling plate so that the inlet is positioned above the center of the multi-spiral fins structure.

Abstract: Various embodiments may relate to a lighting device, including an excitation radiation source and a two-sided luminescent-material wheel. At least one luminescent material is provided on each of the two sides of the two-sided luminescent-material wheel, thus both on the front side and on the opposite back side. The luminescent materials on both sides are excited sequentially in time. For this purpose, at least one transmissive region is provided in the rotating luminescent-material wheel, through which transmissive region the excitation radiation can radiate, which excitation radiation can be deflected onto the luminescent material on the back side by means of an optical unit.

Abstract: A light source arrangement is provided. The light source arrangement may include a plurality of semiconductor laser light sources, each having an optical axis. The semiconductor laser light sources are arranged in such a way that their optical axes are oriented parallel to one another so that respective laser light emission sides of the semiconductor laser light sources point in the same spatial direction. The light source arrangement may further include a deflection unit configured to collect and influence beam paths of the laser light emitted by the semiconductor laser light sources in order to form a beam bundle. The semiconductor laser light sources are arranged on a surface of a carrier, distributed at least two-dimensionally over the surface.
