Description

The invention relates to schemes for illuminating a path in front of a vehicle, for example, a car, in particular to schemes for switching on low beam headlights.

The invention is known (RF patent for invention No. 2183572), in which the process of turning on the lights of a moving vehicle, as well as switching the dipped headlights to the far and vice versa, is automated, using a light beam from an oncoming car or from a general light background, perceiving it as light a sensor, the signal from which is sent to the blocks detecting twilight and the presence of oncoming vehicles. The signals from these blocks are fed to the decryption and priority circuit, which controls the transistors switching the dipped and main beam lamps. The signal of the additional light sensor installed in the rear of the car is fed to the coincidence circuit connected via a different input to the decryption and priority circuit. The coincidence circuit generates a signal only at dusk and when external light devices are turned on, which controls the transistor in the electromagnet circuit of the rear view mirror when the dipped or main beam (dark time of day) is turned on and there is a rear-going vehicle with the headlights on.

The disadvantage of this device is the complexity of the circuit.

The traditional scheme for controlling lighting devices in cars using electromechanical relays is widely known. It includes: the "Dipped beam" switch, the "High beam" switch and electrical relays that act as discrete-type amplifiers, while the transmission of electrical energy is carried out directly from the positive terminal of the battery to consumers.

The disadvantage of such a control scheme for automotive lighting is the low reliability due to the transmission of electrical energy directly from the positive terminal of the battery to consumers. According to the requirements of the traffic rules of the Russian Federation, a situation arises when the "Dipped beam" lighting of automobile vehicles remain on when the engine ignition system is off, which results in the discharge of the vehicle’s battery.

The technical task of the utility model is to develop a simple, reliable, convenient to install and operate circuitry that ensures the inclusion of low beam in accordance with the Rules of the road.

The technical result of the utility model is achieved by the fact that in the control circuit of the lighting devices of vehicles, containing the "Dipped beam" switch, the "Dipped beam" switch and electric relays that act as discrete amplifiers, the dipped relay "Dipped light", the off relay " Dipped beam ", while the dipped-on and off relay" Dipped beam "is powered from the point where the presence of the supply voltage is determined by the position of the engine ignition key and the position of the switch "Dipped beam" and the "Dipped beam" switch.

The figure shows an electrical control circuit for lighting devices of vehicles, such as a car.

The circuit contains a dipped-beam switch 1, a dipped-beam switch 2, a dipped-beam relay 3, a dipped-beam relay 4, normally open contacts 5 of relay 3 and normally closed contacts 6 of relay 4.

In a static state, only the supply voltage is supplied to the vehicle lighting control circuit when the engine ignition key is turned on.

When the “Dipped beam” switch 1 is pressed briefly, the supply voltage is briefly applied to the dipped beam and to the dipped relay. 3. The dipped beam relay 3 is activated. Contacts 5 of the dipped relay switch 3 close and connect the power circuit of the dipped relay switch 3 and dipped beam to the connection point of the positive wire, in which there is a supply voltage from the ignition key of the engine. To turn off the dipped-beam lamps, it is enough to briefly press the high beam switch 2, and the dipped-beam relay is activated 4. Contacts 6 of the dipped-beam relay 4 open and remove the supply voltage of the dipped-beam relay 3. Dipped relay "Dipped beam" 3 opens contacts 5 and the dipped beam lamps turn off. To turn on the high-beam lamps, turn on the “High Beam” switch 2, while the dipped-beam relay is activated 4. When this happens, the low-beam lamps turn off, as described above, and the high-beam lamps turn on, powered by switch 2. When the vehicle is stopped To turn off the dipped-beam lamps, if it was turned on while driving or when parking, it is enough to turn off the engine ignition key, and the supply voltage at the connection point of the plus wire is removed. The dipped beam relay 3 is deactivated. Contacts 5 open and the low-beam lamps turn off, which eliminates the discharge of the vehicle’s battery when the engine ignition system is off.
