Abstract

PURPOSE:To prevent a driver in an opposite car from being dazzled by the sudden lighting of a main lamp by forming an electric supply route from car batteries only to a front dimmer lamp when fixed conditions are satisfied. CONSTITUTION:When a control unit 13 detects that a car is running with the surrounding brightness below a fixed level, a transistor 13-1 is on, and the first and the second relay 19 and 21 are on to supply current to a dimmer lamp 5-2. Even if a dimmer switch 7 is set to the side of a main lamp 5-1, the main lamp 5-1 cannot be lit by the operation of a diode 23, and only the dimmer lamp 5-2 is lit. This construction permits to prevent a driver in an opposite car from being dazzled by the sudden lighting of the main lamp.

1 is a battery; 3 is a lighting switch; 5 is a headlamp; 7 is a dimmer switch that selects whether to turn on the main lamp 5-1 or the dimmer lamp 5-2 in the headlamp 5; 9 is the brightness around the vehicle An optical sensor that detects
Reference numeral 11 denotes a vehicle running detection unit that detects that the vehicle is running, and 13 indicates that the brightness around the vehicle is below a predetermined level and that the vehicle is moving based on the detection signals from the optical sensor 9 and the vehicle running detection unit 11. This control unit turns on the relay 15 to turn on the headlights 5 when it detects that the vehicle is running. Note that reference numeral 17 is an activation switch that supplies battery 1 voltage to the control unit 13 to operate the control unit 13. Further, the on/off switching operation of the relay 15 is controlled by the switching operation of a transistor 13-1 provided at the output stage of the control unit 13.

いずれかが自動的に点灯する。The effect is that when the brightness around the vehicle is below a predetermined level,
Control unit 1 also indicates that the vehicle is running.
3 is detected, the transistor 13-1 provided in the output stage becomes conductive, so current flows through the coil 15-1 of the relay 15, turning on the relay 15, and the battery 1 contacts the contact 15-2. A current flows through the headlamp 5 through the headlamp 5, so that either the main lamp 5-1 or the dimmer lamp 5-2 selected by the dimmer switch 7 among the headlights 5 is automatically turned on.

The headlights automatically turn on without the driver having to operate the lighting switch, so for example, when driving in a tunnel during the day, the driver does not have to operate the lighting switch.
The headlights are turned on and off depending on the brightness around the vehicle. On the other hand, if the dimmer switch is set to the main lamp side, the main lamp will suddenly turn on when certain conditions are met, and other vehicles, especially drivers of oncoming vehicles, will be dazzled by the glare. There is a risk that you will be

In order to prevent the driver from being dazzled, only the dimmer lamp is turned on when the predetermined condition is satisfied, and the main lamp is not turned on even if the predetermined condition is satisfied.

、第１図と同符号のものは同一物を示す。FIG. 2 shows an embodiment of the present invention, in which when the transistor 13-1 provided at the output stage of the control unit 13 becomes conductive, it is turned on and one end of the dimmer lamp 5-2 is connected to the battery. a first relay 19 connected to the ground, and a second relay 19 connected to the earth when the first relay 19 is turned on and driven to connect the other end of the dimmer lamp 5-2 to ground.
When the relay 21 and the dimmer switch 7 are set to the main lamp side and the first relay 19 is on,
A power supply path forming means is constituted by a diode 23 that prevents the current flowing from the battery 1 through the contact 19-1 of the first relay 19 from flowing to the main lamp 5-1. In addition, the first 1 relay 1
The power source of the coil 19-2 of No. 9 is the transistor 13-2.
In order to prevent the first and second relays 19 and 21 from being turned on all the time and the dimmer lamp 5-2 not being illuminated in the event that the first and second relays 19 and 21 fail due to a short circuit, the activation switch is installed. The first relay 19 can be turned off by turning off the first relay 17, so that the first relay 19 can be taken from between the actuation switch 17 and the control unit 13. Also, the same reference numerals as in FIG. 1 indicate the same parts.

Then, the second relays 19 and 21 are turned on, and a current flows in the path from battery 1 → contact 19-1 of first relay 19 → dimmer lamp 5-2 → contact Ji 21-1 of second relay 21 → ground. Therefore, even if the dimmer switch is set to the 7-section main lamp 5-1 side, the main lamp 5-1 will not be lit due to the action of the diode 23, but the dimmer lamp 5-2 will be lit.
