ABSTRACT:
A light reflector imaging a high-intensity light beam includes a reflector part shaped as a portion of an ellipsoid, and a reflector part with two parallel edges, shaped as the zone of a sphere. The smaller parallel edge of the spherical reflector part serves as an aperture. The ellipsoidal reflector part has a rectangular opening offset slightly in one direction from its axis of revolution, and large enough to receive a socket. The ellipsoidal reflector part connects to the larger parallel edge of the spherical reflector part to enclose a lamp. A curvilinear reflector part can be attached to the aperture of the spherical reflector part to more narrowly focus the light exiting from the disclosed light reflector. The curvilinear reflector part is a paraboloidal-like shaped tube, which varies in curve and length according to a desired output angle. Other attachments to the two-part reflector assembly include a thin cylindrical tube into which a glass piece is mounted to cover the aperture. Alternatively, the thin tube can house a collimating lens to further focus exiting light. The majority of light shining from the lamp enclosed by the light reflector takes one of three paths. First, light shining towards the aperture of the light reflector exits directly. Second, light shining towards the spherical reflector part is reflected towards the ellipsoidal reflector part. Third, light shining towards the ellipsoidal reflector part is reflected towards a focal point beyond the aperture, exiting the light reflector through the aperture.
