Abstract

PURPOSE:To enable a dim-dip lamp system to effectively function even in a vehicle having a retractable head lamp, by placing a head lamp retractor in the upper direction and supplying electric power to a low beam light source through a resistor when an ignition switch and a small lamp switch are turned on. CONSTITUTION:If a small lamp switch 10 is turned on with an ignition switch 15 in an on-state or if the ignition switch 15 is turned on with the small lamp switch 10 in an on-state, a control relay 16 is actuated. And a dim-dip retractor relay 12, dim-dip relay 13 and a dimmer relay 8 are actuated. Further a retractor motor 6 is driven placing a head lamp retractor in the upper direction, and power, which is supplied to a low beam filament 4a of a head lamp 4 through a dim-dip resistor 14, turns on the head lamp 4 reducing a beam of light by a predetermined amount smaller than the normal low beam.

Description

Description: FIELD OF THE INVENTION The present invention relates to a dim dip lamp system, and more particularly to a dim dip lamp system in a vehicle equipped with a retractable headlamp.

(Prior Art) The DIM DIP lamp system is provided on a vehicle from the viewpoint of driving stability, and must be installed in the UK. The dim dip lamp system is a system that turns on the head lamp as a dim dip lamp when the ignition switch and the small lamp switch are on. By using a dip lamp, the surroundings are not dark enough to require illumination by a headlamp like at night, but the visibility is configured in a dim situation like in the evening. Regarding the dim dip lamp system, a system in which a low beam of a headlamp is turned on in a dimmed state when an ignition switch is on is disclosed in British Patent No. 1078961.

(Problems to be Solved by the Invention) In a vehicle equipped with a retractable headlamp,
Conventionally, the headlamp retractor is configured to be directed upward or downward depending on whether or not the headlamp is turned on, and the headlamp retractor is not directed upward only by simply turning on the small lamp. Therefore, when the above-mentioned DIM dip lamp system is adopted as it is, even if the ignition switch and the small lamp switch are turned on and the low beam of the headlamp is turned on in a predetermined dimmed state, the headlamp retractor remains downward. Therefore, the headlamp also remains downward, and therefore the DIM dip lamp system cannot perform its function at all.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a dim dip lamp system capable of effectively exhibiting its function even in a vehicle including a retractable headlamp. .

(Means for Solving Problems) The dim dip lamp system according to the present invention is configured such that the head lamp retractor is kept facing upward when the head lamp is turned on as a dim dip lamp in a predetermined dimming state. is there. That is, a dim dip lamp system in a vehicle equipped with a retractable headlamp, when the ignition switch and the small lamp switch are in the on state, the headlamp retractor is in the upward state and a resistance is applied to the light source for the low beam of the headlamp. It is characterized in that it is configured to supply electric power via.

(Operation) With the above configuration, when the ignition switch is turned on and the small lamp switch is turned on, the headlamp retractor faces upward, the headlamp lights up in a predetermined dimmed state, and the front of the vehicle is illuminated as a dim dip lamp.

(Effects of the Invention) Therefore, according to the present invention, it is possible to allow the dim dip lamp system to function effectively even in a vehicle provided with a retractable headlamp.

Embodiment An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a circuit diagram showing a dim dip lamp system according to this embodiment.

The DIM DIP lamp system is incorporated in a power supply circuit for lamps provided in a vehicle, and the cluster switch 1 is used to switch these lamps, particularly headlamps and small lamps. . That is, when the light switch 2 in the cluster switch 1 is turned on, the headlamp relay 3 operates and power is supplied to the low beam filament 4a of the headlamp 4 from the power source (+ B) so that the headlamp 4 lights up in the low beam and the retractor relay The retractor motor 6 is driven by the operation of the motor 5, and the head retractor (not shown) faces upward. When the dimmer passing switch 7 is turned on with the light switch 2 turned on, the dimmer relay 8 operates and the lighting state of the headlamp 4 is switched from the low beam 4a to the high beam 4b. The dimmer passing switch 7 is configured so that, by the action of the dimmer latch circuit 9, the dimmer relay 8 repeats the operation and the restoration every time the switch is operated. In addition, the small lamp switch 10 in the cluster switch 1
When turned on, the clearance lamp and other small lamps (not shown) are turned on.

The dim dip lamp system is configured by incorporating a dim dip controller 11, a dim dip retractor relay 12, a dim dip relay 13 and a dim dip register 14 in the power circuit of these lamps. It seems that.

That is, the ignition switch (1G) switch 15
When the small lamp switch 10 is turned on when is on,
Alternatively, when the small lamp switch 10 is turned on and the ignition switch 15 is turned on, the control relay 16 of the dim dip controller 11 operates, and accordingly, the dim dip retractor relay 12, the dim dip relay 13 and the dimmer relay 8 operate. . As a result, the retractor motor 6 is driven and the headlamp retractor is directed upward, and the dimming register 14 is attached to the low beam filament 4a of the headlamp 4.
Power is supplied through the headlamp 4 and the headlamp 4 is lit in a state where the headlamp 4 is dimmed by a predetermined amount as compared with a normal low beam.

Then, when one of the small lamp switch 10 and the ignition switch 15 is turned off, the control relay 16 of the dim dip controller 11 is restored, so that the dim dip retractor relay 12, the dim dip relay 13 and the dimmer relay 8 are also reset. As a result, the headlamp 4 that has been turned on in the dimmed state is turned off, and at the same time, the retractor motor 6 is driven in the reverse direction, and the retractor is in the downward state.
