CIRCLING GUIDANCE SIGNAL LIGHT Russian patent published in 2000 - IPC

FIELD: spatial light signaling primarily to upper hemisphere. SUBSTANCE: device used as obstruction light and built around light-emitting diodes has case with protective cap that accommodates holder in the form of fitting mounting two, three, or more hollow regular truncated pyramids whose longitudinal symmetry axes are aligned; their side faces carry on their apothems light-emitting diodes with optical axes perpendicular to mentioned faces of truncated pyramids. Each of side faces of mentioned pyramids is perpendicular to axis crossing single optical center on longitudinal symmetry axis of light and emitting center of light-emitting diode mounted on this face. One design version of device has its bottom hollow regular truncated pyramid joined through its lower base with annular convex mirror-reflection member shaped as parabola, that is, made in the form of part of paraboloid whose focal circumference is aligned with emitting centers of light- emitting diodes. EFFECT: improved lighting and thermal characteristics, simplified design. 7 cl, 5 dwg
