HEAD LIGHT BASED ON LIGHT-EMITTING DIODES Russian patent published in 2012 - IPC F21S8/10 

FIELD: electricity.

SUBSTANCE: device contains concave smooth reflector in the form of paraboloid truncated along focal plane behind which in half-space of truncated apex there arranged are fragments of concave elliptic mirrors and light-emitting diodes, each of them is arranged in one of focuses of corresponding fragment of concave elliptic mirror and oriented so that its whole light flux is reflected from fragment of corresponding concave elliptic mirror, at that one part of fragments of concave elliptic mirrors is arranged so that their second focuses are converged and brought into coincidence with focus of concave smooth truncated paraboloid located on symmetry axis of head light, and the other part of fragments of concave elliptic mirrors is arranged so that their second focuses are converged in one of two points on symmetry axis of head light which are displaced relative to focus of concave smooth truncated paraboloid in opposite directions.

EFFECT: providing highly directional integral light beam form set of N light-emitting diodes simultaneously.
