Abstract: A laser reflection unit for a laser phosphor projector. The unit includes a housing and a wheel rotatably drivably received in the housing. The wheel has a top side provided with a phosphor layer for an converting incident laser light beam into a reflected light beam. Further, the wheel has a bottom side opposite to the top side, the bottom side being provided, at a radial outward annular portion from a center axis of the wheel, with cooling fins inducing an air flow flowing in a radial outward direction. The laser reflection unit further includes a heat exchanger received in the housing for cooling the air flow flowing from the wheel, the heat exchanger extending along a mainly circumferential contour coaxial with the center axis of the wheel. The housing is provided with an inner surface guiding the air flow from the wheel towards and along the heat exchanger.

Abstract: The fabric-reinforced rigid foam supporting element claimed having a total thickness of <10 mm is characterized in that it has been produced completely by machine. As a result of the specific features and the preferred production process, supporting elements which have a low thickness and do not differ in terms of their stiffness and strength from supporting elements having thicknesses above 10 mm are obtained. They are therefore outstandingly suitable as insulation materials in building and construction, in particular for constructions, and also for thermal and and/or acoustic insulation.
