Patent ID: 8083379

Claim:
A reflector emitter for producing a directed light beam, comprising: a combination reflector including: at least two elliptical concave mirrors each having a form of a section of an ellipsoid of revolution having first and second focal points, each of the elliptical concave mirrors being cut, between its center and the first focal point, in a longitudinal section plane extending through the focal points and in a cross-sectional plane perpendicular to a line connecting the focal points so as to form at least two ellipsoid of revolution sections each having the first and second focal points disposed outside and inside of the ellipsoid of revolution section, respectively; an other concave mirror having at least one focal point that coincides with the first focal point of each of the ellipsoid of revolution sections, the other concave mirror having a form of a hollow body cut in a sectional plane through the at least one focal point; and an aperture disposed vertically above the other concave mirror; and at least one light source disposed at the second focal point of each of the ellipsoid of revolution sections, wherein the longitudinal section plane of the ellipsoid of revolution sections and the sectional plane of the other concave mirror are disposed in a common plane of reference, and wherein the at least two elliptical concave mirrors and the other concave mirror have respective faces that oppose each other such that, with respect to the plane of reference, the directed light beam exits through the aperture on the same side of the plane of reference as the at least two elliptical concave mirrors.
