Abstract

The invention discloses a light beam excitation type automobile lamp intelligent power-off protection system. The light beam excitation type automobile lamp intelligent power-off protection system mainly consists of an integrated chip AL, a control circuit, a timer connected with the OUT1 pin of the integrated chip AL, a light-dependent resistor RL connected with the control circuit, an overvoltage protection circuit connected with the CTRL pin of the integrated chip AL, a relay K connected with the overvoltage protection circuit and a diode group connected between the control circuit and an automobile lamp switch J in series and is characterized in that a light beam excitation type logic amplification circuit is further connected between the integrated chip AL and the control circuit in series. The ight beam excitation type automobile lamp intelligent power-off protection system can automatically turn off a power supply when a driver forgets to turn off an automobile lamp, accordingly can effectively and completely eradicate the situation that electric energy of a vehicle-mounted storage battery is exhausted and prolongs the service life of the automobile lamp and the storage battery to the greatest extent.

Description

technical field [0001] The invention relates to a protector, in particular to an intelligent power-off protector for automobile lamps which can intelligently shut off the automobile lamps. Background technique [0002] Cars are the most widely used means of transportation at present, but many car drivers often forget to turn off the headlights after parking. When the car is restarted next time, the electric energy of the car battery has been exhausted, and the engine cannot be restarted. Case. In addition, sometimes when the vehicle is running, the headlights are turned on in broad daylight, and the driver does not know it at all, which will not only seriously reduce the service life of the lights, but also shorten the service life of the battery, which is not conducive to the current energy-saving needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that there is no car light device that can automatically turn off the c...
