MULTI-FUNCTIONAL FRONT HEADLIGHT ON LIGHT DIODES Russian patent published in 2011 - IPC F21S8/10 

FIELD: machine building.

SUBSTANCE: to obtain separate lights of front multi-functional headlight (MFH) there are used narrow-degree light diodes with double scattering angle for white light (lower beam - 2Θ_0.5=(2±0.5)°, 2Θ_0.01=(3±0.5) ° and upper beam 2Θ_0.5=4-8°), of short wave IF-radiation (total blackout - blanking) of blue, blue-green and yellow light (partial blackout - 2Θ_0.5=2-7°). Light distribution of the head light is formed with lens diffusers and/or prismatic elements simultaneously corresponding to protective glasses of each of a group of light diodes, or is achieved with turn of optical axes of light diodes. At output of radiation of partial blackout light diodes there can be installed a light screening device made in form of a volume cavity, for example, in form of a truncated parallelepiped consisting of two zones: light diodes directionally radiating through a narrow light optical gap into the second zone (into a low hemisphere) for lightning road surface are placed in the first zone. Light diodes can be connected to electronic inverters and can be controlled with autonomous remote control.

EFFECT: raised efficiency of light blackout, simplified design, reduced cost and power expenditures.
