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: An illuminating device may include a light source, an optical unit configured to adjust direction of light from the light source, a reflector, a light pipe, and an exciter. The light pipe may receive light having a first wavelength from the optical unit and direct the light having the first wavelength onto the exciter. The exciter may convert the light having the first wavelength into light having the second wavelength and reflects the light having the second wavelength to the reflector. A circumferential wall of the light pipe is configured to reflect the light having the first wavelength and to transmit the light having the second wavelength.

Abstract: A lighting device comprising a pump laser matrix (2) and a phosphor arrangement. The pump laser matrix (2) is configured to emit pump radiation (7) having a controllable pump radiation power distribution for the irradiation of the phosphor arrangement (4). The phosphor arrangement (4) comprises at least two different phosphors (R, Y, G) which can be irradiated with the pump radiation (7) and re-emit said pump radiation in a manner such that it is at least partly and in each case differently wavelength-converted. The lighting device (1) is configured to generate, with the aid of the pump laser matrix (2), a controllable distribution of the surface power density of the pump radiation on the phosphors (R, Y, G) of the phosphor arrangement (4).
