減光された状態で点灯する。In FIG. 1, 1 is a battery, 2 is a lighting switch, 3 is a dimmer switch, and 4 is a headlamp. A relay 5 is installed in the headlamp lighting circuit from the lighting switch 2 to the dimmer switch 3. , the relay 5 is operated by a relay control device 6 operated by a signal from a vehicle speed sensor 7,
When the vehicle is running, the headlight lighting circuit powered by the battery 1 is closed as shown by the solid line, and when the vehicle is stopped, the relay 5 is connected to the contact s on the low voltage source 8 side, such as the neutral point of the on-board alternator.
b, and the headlight 4 is turned on in a dimmed state using the low voltage source 8 as a power source.

。In the headlight lighting device that automatically dims or turns off the headlights when the vehicle is stopped according to the signal from the vehicle speed sensor as described above, in the present invention, the control device 6 includes a lamp on the right side (RH side) of the turn signal switch 10. A circuit 12 is provided that sends a signal when the vehicle is turned on, and even if the vehicle speed sensor 7 issues a vehicle stop signal based on the signal from the circuit 12, the control device 6 is not activated and the relay 5 is activated as shown by the solid line, just as when the vehicle is running. contact sb
It is constructed so that the side can be kept closed.
第１図装置の具体的回路構成例を第２図に示す。A specific example of the circuit configuration of the device shown in FIG. 1 is shown in FIG.

されている。In FIG. 2, the vehicle speed sensor 7 is composed of a magnet Mg that rotates in conjunction with the speedometer cable and a reed switch R8W whose contacts are operated intermittently by the rotation of the magnet Mg.

A driving signal as shown in Fig. 3A is continuously output to the point, and this output is differentiated as shown in Fig. 3B in a differentiating circuit consisting of a capacitor C1 and a resistor R1, and a driving signal as shown in Fig. 3C is input to the capacitor C2. A waveform like this is input.

灯４は定格点灯している。Therefore, the transistor T.gamma.1 becomes conductive, and the transistor T.gamma.2 becomes non-conductive, and the coil of the relay 5 is not energized, so that the Sa side of the relay 5 is closed, and the headlamp 4 is turned on at its rated value.

Then, Tγ1 becomes non-conductive, Tγ2 becomes conductive, the coil of relay 5 is energized, the relay 5 switches to the sb side, and the headlamp 4 is powered down by the low voltage source 8 (for example, the neutral of the alternator).

The time T until the headlights turn off (refer to Figure 3) is determined by the capacitance of capacitor C2, the values of resistors R2 and R3, etc.; It is desirable to set T to about 1 to 2 seconds so as not to cause discomfort to the driver by meaninglessly repeating the light (or turning off the light).

灯４は定格点灯を続ける。When the vehicle is stopped to make a right turn, the voltage of the turn signal unit 9 is applied from the turn signal switch 10 to the capacitor C2 via the circuit 12, so the transistor Tγ1 continues to be conductive, and the transistor Tγ2 is non-conductive, causing the front Illumination light 4 continues to be lit at its rated value.

回路６間に設けなければならない。Furthermore, in Japan, vehicles drive on the left, so as in the above embodiment, when the right lamp of the turn signal switch 10 is turned on, a signal is sent from the circuit 12 to the control circuit 6, and the headlight 4 is turned on at its rated value even when the vehicle is stopped. However, if the vehicle drives on the right, as in the United States, for example, the control circuit for turning on the left (LH side) lamp of the turn signal switch 10 will naturally prevent the headlight 4 from dimming or turning off when turning left. A circuit 12 must be provided between the control circuit 6 and the LH side so as to issue a signal to the control circuit 6.

向上に寄与するところ極めて犬なるものである。As described above, in the present invention, in a device that detects a stop using a vehicle speed sensor when a vehicle is stopped and automatically dims or turns off the headlights based on a stop signal from the vehicle speed sensor, one contact of the turn signal switch is provided. By adding a circuit that cancels the vehicle stop signal of the vehicle speed sensor when the vehicle is turned on, the headlight is activated when the vehicle stops near the center of the intersection when turning right when driving on the left, or when turning left when driving on the right. The light maintains the rated lighting, improves the visibility of the vehicle's stopping position to oncoming vehicles, and prevents vehicle collisions or collisions, and is extremely important in contributing to improving vehicle safety. It is something.
