摘要

Electronic device to avoid glare to the drivers of motor vehicles, essentially characterized by the fact that it is a photoelectric tube which, due to the excitation received from the headlights of the vehicle approaching in the opposite direction, produces corresponding tensions in the line. Control of an electronic valve that works as a voltage preamplifier by injecting the obtained signal into a power amplifier tube whose circuit contains a relay that, because the light-exciter current is sufficient, produces the permutation of contacts that turn on the long-distance headlights or those of crossing, also comprising the device, a power supply with transformation to alternating current and how many capacitors and resistors of suitable characteristics are necessary according to the technique for the purposes pursued.
