DEVICE FOR LIGHT-BEAM TREATMENT Russian patent published in 1995 - IPC

FIELD: lighting engineering. SUBSTANCE: device has optical radiation point source 1 and concentrating reflector 2 with reflecting surface, which is made in form of body of rotation. Generating line of body of rotation of concentrating reflector is formed by arcs of confocal ellipses and cuts of beams, which connect them together (the beams incident from focal point, which is coincided with radiation source, and/or arcs of circles, which have centers in this focal point). Sizes of parts of boundary and their mutual dispositions are set according to requirements for more complete collection of radiation from point source at focal point area, which point is brought into coincidence with surface of material to be treated (shape of the reflector may vary at wide range). EFFECT: improved efficiency of operation. 1 dwg
