LED LIGHTING FIXTURE CONTAINING LIGHT BEAM GEOMETRY CONTROL DEVICE Russian patent published in 2017 - IPC H05B37/02 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting fixtures, equipped with light-emitting diodes (LED), in particular, to head lamp with variable geometry beam forming device. Result is achieved by fact, that lighting fixture comprises light source, containing one or more light-emitting diodes (LED), power supply unit (100) to supply electric power to said light source, wherein control over light source brightness is carried out by first control information or first control signal; control device (306) to control over generated by light source light beam geometry as response to second control information or second control signal and control unit (200) for generating of first and second control information or first and second control signals, upon that control unit (200) includes image sensor (210), capable to generate, at least, one image of point illuminated by said light source, and said image processing device (230) in order to generate first and second control information or first and second control signals.

EFFECT: technical result is providing of lighting fixture having adaptive control mechanism, as well as increasing battery service life.
