Problems solved by technology

[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. This 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.

Abstract

The invention discloses an automobile lamp turn-off forgetting alarm apparatus based on a light beam excitation circuit and a logic protection circuit. The automobile lamp turn-off forgetting alarm apparatus is mainly composed of a loudspeaker HA, a control circuit and a light resistor RL, wherein the control circuit is connected with the loudspeaker HA, and the light resistor RL is connected with the control circuit. The control circuit comprises a triode Q1, a triode Q2 and a resistor R1, wherein one end of the resistor R1 is connected with a base electrode of the triode Q1, and the other end of the resistor R1 is externally connected with an automobile engine switch. The automobile lamp turn-off forgetting alarm apparatus is characterized by being further provided with a light beam excitation type logic amplification circuit and a logic protection emitter coupled type amplification circuit, wherein the light beam excitation type logic amplification circuit is connected with the base electrode of the triode Q1, and the logic protection emitter coupled type amplification circuit is connected between the light beam excitation type logic protection circuit and a negative electrode of the loudspeaker HA in series. According to the automobile lamp turn-off forgetting alarm apparatus, an alarm can be automatically given when a driver forgets to turn off automobile lamps, so that the phenomenon that a vehicle-mounted storage battery is used up is effectively eradicated, and the service life of automobile lamp bulbs and the service life of the storage battery are prolonged to the greatest extent.

Description

technical field [0001] The invention relates to an alarm, in particular to an alarm for forgetting to turn off the lights of an automobile based on a light beam excitation circuit and a logic protection circuit. 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 device on the market that can r...
