FIELD: lighting devices or systems.
SUBSTANCE: anti-glare head-light has a source of parallel light beams and stack of flat parallel plates made of a transparent dielectric and mounted at the Brewster angle to the beam. The additional stack of transparent dielectric plates is inserted into the beam reflected from the main stack. The nontransparent gate is inserted into the beam passed through the main stack. The gate is connected to the electronic controller through a servomechanism. The electronic controller is provided with light sensors.
EFFECT: enhanced efficiency.
