Document Type and Number:
Japanese Patent JP4954288
Kind Code:
B2
Abstract:
A reflector emitter includes a combination reflector having at least one elliptical concave mirror shaped as an ellipsoid of revolution section having first and second focal points disposed outside and inside of the ellipsoid of revolution section, respectively. The reflector emitter includes at least one light source at the second focal point. The ellipsoid of revolution section is formed as an ellipsoid of revolution that is cut between its center and the first focal point in a longitudinal section plane and in a cross-sectional plane. An aperture is provided above an other concave mirror having at least one focal point that coincides with the first focal point of the ellipsoid of revolution section. The other concave mirror is formed as a hollow body cut in a sectional plane through its focal point. This sectional plane and the longitudinal section plane of the ellipsoid of revolution section share a common plane of reference and the concave mirrors have opposing faces.
