Abstract: A projection apparatus comprising a light source, an image display device and at least one filter device for transmitting a first portion of the radiation from the light source in a first wavelength range in the visible range to the image display device, and for diffusely reflecting a second portion of the radiation in a second wavelength range outside the visible range.

Abstract: The subject matter of the disclosure is a PAR lamp arrangement having an integral lamp, in particular an integral halogen lamp, which is inserted into a base and is surrounded at least in sections by a reflector, the base and the integral lamp being connected via contact springs, and the reflector being covered by a diffusing screen. According to the invention, the reflector is made from aluminum and is provided with a reflective surface or coating. Owing to the aluminum reflector used and the fact that the integral lamp is held via contact springs, improved holding of the integral lamp is made possible with reduced weight and production complexity.
