[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is for a vehicle having a plurality of auxiliary headlights in addition to the headlight, for vehicles in which the auxiliary headlight side is also switched to a lighting state of the same character by interlocking with the lighting state of the headlight. The present invention relates to a lighting control device for a light.

[0002]

[Prior art]

 As is well known, vehicles such as passenger cars are equipped with various types of lighting devices (headlights, auxiliary headlights, small lamps, clearance lamps, etc.). From this point of view, various bylaws are set as security standards.

[0003] For example, in the case of a headlight, a high beam lighting (upward lighting that illuminates a long distance of about 40 m or more) and a low beam lighting (down lighting that illuminates a short distance of less than about 40 m) ) And) are switched appropriately, and they are normally used for low beam lighting when driving in urban areas or with oncoming vehicles, and for high beam lighting when there are no oncoming vehicles or when passing.

In vehicles having such headlights, in recent years, particularly in off-road vehicles and RV vehicles, in accordance with the lighting state of the headlights, that is, when the headlights are on the high beam, It is possible to obtain a high beam compatible lighting state of the same character as the lighting, and to obtain a low beam compatible lighting state of the same character as the low beam lighting when the low beam lighting is performed. The number of cases where auxiliary headlights (fog lights, etc.) are attached are increasing.

[0005]

[Problems to be solved by the device]

 However, a plurality of auxiliary headlights having different lighting characteristics are usually retrofitted. In this case, the operation switch for the auxiliary headlights (switch for the auxiliary headlights) is installed as an independent switch near the steering part and around the driver's seat, but it is a control switch for the above headlights and small lamps. Since it is not linked with the light combination switch (usually an operation switch consisting of a rotary lever switch mechanism attached to the steering part), the blinking operation is not only troublesome but also dangerous for driving. there were. This is because, for example, when the high beam is on or when an oncoming vehicle suddenly appears, the light combination switch must be used to switch the headlights to low beam and at the same time the auxiliary headlight switch must be operated.

Further, according to the safety standard for a lighting device such as a headlight, it is required that the structure is such that three or more lights cannot be turned on at the same time. I need to put it.

The present invention has been made in view of such a conventional situation, and is for a vehicle in which at least the auxiliary headlight side is switched to the lighting state of the same character in conjunction with the lighting state of the headlight. It is intended to provide a lighting control device for the light.

【Example】

 FIG. 1 shows an embodiment of a lighting control device for a vehicle light according to the present invention. In the figure, 1 is a headlight (headlight) having a light emitting body 1a for high beam lighting and a light emitting body 1b for low beam lighting, and 2 and 3 are high beam lighting of the headlight 1 and corresponding to a high beam. A plurality of fog lights, etc., each independently equipped with a light-emitting body 2a for obtaining a lighting state and a light-emitting body 3a for obtaining a lighting state corresponding to the low beam of the headlight 1 having a low beam Auxiliary headlight, 4 is a switch for auxiliary headlights having a plurality of interlocking switch parts 4a to 4c, 5 is a switching relay for switching the lighting states of the auxiliary headlights 2 and 3, and 6 is a small lamp. Reference numeral 7 denotes a light combination switch for the headlight 1, the small lamp 6 and the like.

The light combination switch 7 is a switch composed of a rotary lever switch mechanism usually attached to the steering portion. For example, when the rotary lever is turned clockwise one step from the power-off state, the switch portion 7a The movable contact portion of the power source is turned on, power from the battery power source is supplied to the power source line L ₂ of the light emitting body 6 such as a small lamp through the power source line L ₁ , and the light emitting body 6 is turned on. ing. Further, when it is further turned clockwise by one step, the ON state of the switch section 7a is maintained as it is, and the movable contact section of the switch section 7b further ahead is connected to the low beam lighting power supply line L _{3 of the} headlight 1. Then, the low beam lighting emitter 1b is turned on to obtain the low beam lighting. Further, in this state, for example, if the rotary lever is moved up and down, the movable contact of the switch portion 7b is moved. The part is connected to the high beam lighting power supply line L _{4 of the} headlight 1 and turned on, and the high beam lighting luminous body 1a is lit up to high beam lighting (for example, normal high beam lighting when the lever is lowered, automatic reset type). When the lever is raised, instant flashing lighting) is obtained.

Of the plurality of interlocking switch parts 4 a to 4 c of the auxiliary headlight switch 4, the interlocking switch part 4 a switches the ON signal when the high beam of the headlight 1 is turned on and the contact on the electromagnetic coil side of the relay 5 It is interposed in the power supply line L ₅ for inputting to the unit 5a, and the interlocking switch unit 4b is interposed in the power supply line L ₆ that supplies the power from the battery power source to the switch unit 5b of the switching relay 5, and , interlock switch unit 4c have been interposed power from battery power while supplying the power supply line L ₂ to the light-emitting element 6, such as a small lamp, in a single operation, all the interlock switch unit 4a~c is switched Growling.

In addition, the movable contact portion of the switch portion 5b of the switching relay 5 is provided with the auxiliary headlamp 3 for low-beam correspondence, which is always lit when there is no ON signal (energization current) for high-beam lighting of the headlamp 1. It is connected to the power supply line L ₇ side for lighting, and when there is an ON signal at the time of lighting the high beam of the headlight 1, the electromagnetic coil side of the switching relay 5 is excited and an auxiliary for lighting for high beam is provided. The headlamp 2 is switched and connected to the power line L ₈ side for lighting the headlamp 2.

According to the lighting control device for a vehicle light according to the present invention configured as described above, first, the switching relay 5 is installed in an engine room or the like, and the auxiliary headlight switch 4 is provided in the steering portion. Install it in a place near the driver's seat that is easy to operate, and provide the required wiring.

When the auxiliary headlight switch 4 is in the OFF state, the light combination switch 7 can perform normal light control (lighting control of the headlight 1 and the like) without any trouble. No current flows in the auxiliary relay headlamps 2 and 3 as well as in the electromagnetic coil side of the switching relay 5. That is, when the switch is turned off, there is no useless energization or spontaneous discharge due to the energization.

On the other hand, when the auxiliary headlight switch 4 is turned on, all the movable contact parts of the interlocking switch parts 4a to 4c are turned on. Accordingly, first, the interlocking switch part 4b and the switching relay 5 are connected. the switch portion 5b, through a power line L _7, auxiliary headlamps 3 of the low beam pairs応点lamp is turned on. In other words, the low beam corresponding lighting state of the fog lamp can be obtained. At the same time, interlock switch section 4c, through a power line L _2, light emitter 6, such as small lamps are also illuminated. This automatically achieves the safety standard that the small lamp must always be turned on when the fog lamp is turned on. At this time, if the light combination switch 7 is in the OFF state, the low beam compatible lighting state of the auxiliary headlight 3 and the lighting state of the small lamp and the like are maintained.

In the above state, when the light combination switch 7 is rotated one step to turn on the switch portion 7a, the light emitting body 6 such as a small lamp is energized through the power line L ₁ . In this case, since the light-emitting body 6 has already been turned on in conjunction with the turning-on of the auxiliary headlight 3, it is maintained as it is.

Then, when the light combination switch 7 is further rotated by another step to turn on the switch portion 7b, first, the movable contact portion of the switch portion 7b is connected to the power supply line L _3. Therefore, the light emitting body 1b for low beam lighting is turned on, and low beam lighting centering on short-distance illumination is obtained.

Next, when the light combination switch 7 is moved up and down from the above state, the movable contact portion of the switch portion 7b is connected to the power supply line L ₄ this time, and thus the light emitting body 1a for lighting the high beam is lit. As a result, high beam lighting centered on normal long-distance lighting can be obtained. When the high beam is lit, the power from the power line L ₄ is supplied to the electromagnetic coil side contact part 5a of the switching relay 5 through the power line L ₅ of the additional wiring and the interlock switch part 4a of the auxiliary headlight switch 4. Therefore, the switching relay 5 is switched et al is, since the movable contact of the switch portion 5b is connected to the power supply line L _8, the auxiliary headlamp 2 for high beam corresponding lighting is turned on. In other words, the high beam corresponding lighting state of the fog lamp can be obtained.

As described above, in the device of the present invention, if the headlamp 1 is switched during high beam lighting, the auxiliary headlamp side also operates in a high beam compatible lighting state of the same character as this high beam lighting. Obtained automatically. Of course, at this time, one of the auxiliary headlamps for low beam lighting is turned off, so the safety standard that three or more lights should not be turned on at the same time is automatically achieved. Then, if the headlight 1 is returned to the low beam lighting from the high beam lighting, the ON signal (current energization) from the power supply line L ₄ to the switching relay 5 disappears, so that the switching relay 5 is switched and the auxiliary headlight is also provided. On the light side, the low beam compatible lighting state, which is the same character as this low beam lighting, is automatically obtained.

In the above embodiment, the auxiliary headlamps 2 and 3 have independent shapes, but the present invention is not limited to this, and the two light emitters 2a, 2a, 3a may be stored internally. Further, a relay having a holding circuit added to the electromagnetic coil side is used as the switching relay 5, and when the light combination switch 7 is turned off, both auxiliary headlamps 2 and 3 are appropriately operated by operating the auxiliary headlight switch 4. It is also possible to be able to switch.

[Effect of device]

 As is apparent from the above description, the lighting control device for a vehicle light according to the present invention has the following excellent effects.

(1) A plurality of auxiliary headlights such as a fog lamp can be switched in association with a switching operation of the headlights (headlamps).

(2) In addition, the auxiliary headlights are also lit in the same manner (high beam-compatible lighting state or low beam lighting state) by interlocking with the lighting state of the headlights (high beam lighting or low beam lighting) instead of simply switching. It can be switched to the corresponding lighting state). Therefore, especially when both headlights and auxiliary headlights are traveling with the high beam lighting or the high beam compatible lighting state, even if an oncoming vehicle suddenly appears, each operation switch can be operated as before. One-point operation with a normal light combination switch, etc., without any operation, allows quick response, which provides great convenience and avoids danger. Of course, the same is true when passing.

(3) By this interlocking switching, in addition to the headlights, two auxiliary headlights will not be turned on at the same time, so it is said that no more than three lights should be turned on at the same time. The advantage is that security standards are automatically achieved.

(4) Further, by adopting a switch for an auxiliary headlight having a plurality of interlocking switch parts, the auxiliary headlight side is separated from the headlight (for example, by turning off the light combination switch). It is also possible to control only the lighting. In this case, there is also an advantage that the safety standard that the small lamp must be turned on when the auxiliary headlight is turned on is automatically achieved by the function of the continuous switch.

(5) Further, when the switch for the auxiliary headlight is turned off, the additional wiring, especially the electromagnetic coil side of the switching relay is not energized at all, so that spontaneous discharge from these parts and wiring portions is caused. A power-saving structure with almost no such problems can be obtained.
