FIELD: electrical engineering.SUBSTANCE: spotlight contains a concave body in the shape of a conic or pyramidal frustrum made of a heat conductive material, finned on the rear side and having a round, oval or rectangular outlet hole with a protective glass, with high output /1-5 W/ LEDs assembled inside, as well as a chamber with a power supply and s control unit. Arranged on the body inner side walls is a cascade of steps, coaxially positioned and matching the shape of the outlet hole; mounted on the steps in a thermal contact are frames made of a thermally conductive material forming the fins of the conductive heat removal inner radiator; assembled on such fins in thermal contact are LED modules, lines of LEDs or individual LEDs with optic axes simultaneously displaced in sagittal and meridional planes and mutually parallel. mounted on the LEDs may be secondary optic elements such as menses generating a uniform, narrower irradiation flux. The frames may have external flanging made of L-shaped profile and are mechanically clamped to the walls of each step simultaneously with the boards of LED modules or lines with an aluminium foundation.EFFECT: extension of the spotlight functional capabilities through provision for the irradiation type control function.6 cl, 6 dwg |
