Spotlight with point-shaped source, reflector and condenser lens - has additional rotationally symmetric dispersion lens diffusing beam in section of room

摘要

The spotlight contains a high power lamp with an approximately point-shaped light source. It has a hemispherically-shaped reflector and a condenser lens in front of the lamp to align the beams in a parallel direction. The dimensions are relatively small and the light reflected is very powerful. The condenser lens (4) is fitted behind a dispersion lens (6) which distributes the light to a given area in the room. The dispersion lens is concave on both sides and is rotationally symmetric. There is a filter plate (4) between the diffusion lens and the condenser lens. The emerging light beam will be diffused.
