WIPO Patent Application WO/2010/116705
Kind Code:
A1
Abstract:
A light-emitting system is provided with a main mirror (11), which has a central aperture, and has the shape of a portion of a convex parabolic surface with rotational symmetry; a re-reflecting mirror (12), which re-reflects the light reflected by the main mirror (11), and has the shape of a portion of a concave parabolic surface with rotational symmetry; and a lens barrel (14), which holds at least one lens, where said at least one lens images the light reflected by the re-reflecting mirror (12). The location of the front principal point of the at least one lens is the same as the focal point of the re-reflecting mirror (12). The optical axis of the at least one lens is inclined with respect to the axis of symmetry of the parabolic convex surface and the parabolic concave surface.
