Abstract: A Catadioptric Light Distribution System that collects and collimates the hemispherical pattern of light emitted by a Lambertian light emitting diode (LED) into a collimated beam directed essentially parallel to the optical axis of the LED. The system comprises a circular condensing lens having a center axis that is aligned with the optical axis of the LED parabolic reflector having circular opening formed therethrough which is centered on the center axis of the parabolic reflector and a double bounce mirror. The light reflected and culminated by the parabolic reflector is directed onto the circular annular double bounce mirror so that this light is collimated in an annular beam which passes around the edge of the condensing lens.

Abstract: A bean roasting system (10) is provided for use on a barbecue grill (12). The system includes a housing member (22) generally formed as a cylindrical tubular member, formed from a metallic composition with a mesh or plurality of openings which will allow convective heat to pass within the housing member (22). The system includes a rotational mechanism (36) for rotating the housing member (22) about its longitudinal axis. The rotational mechanism includes a motor mechanism (44) coupled to an axially directed rod (48) which extends through and is coupled to housing member (22) for causing housing member (22) to rotate about its longitudinal axis. First and second bracket members (70 and 72), respectively, releasably coupled to opposing end walls of barbecue grill (12), rotatively support axially directed rod (48) so as to permit housing (22) to rotate over barbecue grill (12).
