LIGHT-EMITTING-DIODE LAMP Russian patent published in 2004 - IPC

FIELD: electro-radio engineering, applicable in light and light signal devices, in particular, in obstruction lights, explosion-proof light devices, blackout lights of airfields, helicopter aerodromes, etc. SUBSTANCE: the lamp has a central rod and groups of light-emitting diodes enveloping it with current-conducting leads assembled on plates, made in the form of flat polygonal boards, at least one light-emitting diode, whose optical axis is perpendicular to the side or rib of each board oriented to the environment, is installed at least on one of them, and the current-conducting leads are positioned on the board surface. The polygonal boards with light-emitting diodes may be installed on hinged joints assembled on the opposite ends of the central rod for azimuthal angular turn relative to the lateral axis of the lamp with fixation in the preset position. An additional board may be installed in the lamp perpendicularly to the central rod adjoining the polygonal boards in the lower part. Light-emitting diodes with radially oriented optical axes may also be installed on it. EFFECT: simplified structure and provided spatial variation of light distribution. 7 cl, 4 dwg
