Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lighting device for a vehicle which is useful when a car is put in a garage or traveling on a narrow alley where obstacles are present at night or the like.

[0002]

[Prior art]

 Automobiles are required to be equipped with headlights, headlights, clearance lights, tail lights, brake lights, and back lights as outdoor lights. However, vehicle width lights and tail lights, called headlights and small lamps, are usually turned on and off by operating switches (outdoor lighting switches) provided near the driver's seat in the vehicle. . However, the above-mentioned lighting equipment alone is not always sufficient, and often impinges on nearby obstacles or loses wheel due to poor visibility.

[0003] Therefore, for example, a fog lamp is mounted on the front of the vehicle body for traveling in fog, or a CCD camera or the like is mounted on the rear of the vehicle body separately from the lighting so that the safety of the rear can be checked, so that the image by this can be monitored in the vehicle. In some cases, this is done.

[0004]

[Problems to be solved by the invention]

 However, in each case, only the visibility of the front and rear of the vehicle body has been improved, and the fact that the safety of the side of the vehicle body still has to rely on the mirror mounted on the vehicle body still remains. For this reason, at night or the like, the visibility of the side, particularly the left side (passenger seat side), is poor. For example, when entering the garage, the rear side of the vehicle body may hit an obstacle in the garage. When riding on narrow alleys, the driver sometimes got off the wheel. In some cases, a non-contact type sensor called a corner sensor for object detection is attached to the corner of the vehicle body, but this is not only a very expensive object, but also an object detection, so it is caused by dewheeling. Road shoulders and gutters cannot be detected.

The present invention has been made in view of the above circumstances, and a purpose thereof is to improve the visibility of the rear side when driving a car in a dark environment such as at night. By doing so, it is possible to prevent derailing or collision with obstacles due to inner wheel differences when traveling on narrow alleys.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an illuminating device for an automobile, comprising an illuminator body attached to a rear portion of a vehicle body for locally illuminating a lateral area from the rear portion of the vehicle. The main body includes a luminous body that ignites by obtaining the power of a battery mounted on the vehicle, and an operation switch provided in the vehicle is interposed in a transmission system connecting the luminous body and the battery. An automotive lighting device is provided.

[0007] In particular, in the above-mentioned lighting device, the operation switch comprises a dedicated main power switch and an existing outdoor lighting switch for turning on a vehicle width lamp and the like, and the light emitting element is turned on when both switches are turned on. Is configured to light up.

In addition, the illuminator main body includes a cylindrical outer body containing a light emitting body, and a lens fixed to one end of the outer body, and a high-brightness LED is used as the light emitting body.

[0009]

[Embodiment of the invention]

 Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a state in which the lighting device according to the present invention is mounted on an automobile. In FIG. 1, reference numeral 1 denotes a vehicle body, 2 denotes a rear bumper which forms a part thereof, 3 denotes an illuminator main body which forms a main part of the automotive lighting device of the present invention, and the illuminator main body 3 is, for example, on both sides of the rear bumper 2. In particular, it is attached to the passenger seat side (left side). Then, according to the illumination device of the present invention, it is possible to irradiate the illumination light L from the illuminator main body 3 attached to the rear part of the vehicle body toward the lower part of the side, and locally illuminate the side area of the rear part of the vehicle body.

Here, a preferred embodiment of the illuminator main body 3 will be described with reference to FIG. 2. Reference numeral 4 denotes a luminous body constituting a light source for illumination, and the luminous body 4 is red light, yellow light in this embodiment. Or an epoxy resin-encapsulated light-emitting diode using a lead frame that emits blue light, etc., which is also a gallium arsenide phosphorus (GaAsP) -based high-brightness LED with a luminous intensity of several tens of mcd to several cd, In particular, a multi-lamp is formed by bundling a plurality of these (four in this example). Then, the luminous body 4 is fixed inside the outer case 6 while being mounted on the substrate 5.

The outer case 6 is a cylindrical component having a light-shielding property, and in the present embodiment, the outer case 6 is made of aluminum. On the other hand, reference numeral 7 denotes a lens having a light transmitting property. The lens 7 is made of, for example, transparent plastic and is fixed to one end of the outer body 6 so as to cover the light emitting body 4.

The illuminator main body 3 configured as described above is mounted inside the rear bumper 2 in a state where the lens 7 is exposed from the mounting hole 8 formed in the corner of the rear bumper 2 as shown in FIG. . Reference numeral 9 denotes a mounting flange fixed to the periphery of the lens 7, which is a ring-shaped part made of, for example, rubber or resin, and the back surface of which is formed by an adhesive tape or an adhesive. It is designed to be fixed to the periphery.

Here, the luminous body 4 is lit by obtaining electric power of a battery mounted on the automobile. For this reason, the substrate 5 has a transmission system 10 (electrical wiring system) for connecting the luminous body 4 and the battery. ) Is connected.

Referring to FIG. 3, the transmission system 10 will be described. Reference numeral 11 denotes a fuse (1 amp), reference numeral 12 denotes a male male terminal of the form, and reference numeral 13 denotes a female terminal of the same. As a result, the transmission system 10 is extended. In particular, the illuminator body 3 including the light emitter 4 is connected to the transmission system 10 as described above, and a main power switch 14 is provided as an operation switch for opening and closing a circuit connected to the light emitter 4. .

As shown in FIG. 4, the main power switch 14 is provided inside the vehicle and near the driver's seat. As the mounting position, for example, a center console portion is set as shown in the figure, so that the driver can easily operate the main power switch 14 while driving.

On the other hand, as shown in FIG. 5, in the transmission system 10, the section between the main power switch 14 and the illuminator main body 3 is wired in a concealed state using the space inside the vehicle body, and the main power switch 14 The battery section is drawn out to the engine room through the dashboard.

As described above, the luminous body 4 is connected to the battery via the transmission system 10 to obtain the power thereof and is turned on. However, the transmission system 10 is connected to the main power switch 14 and other components in series with the main power switch 14. The existing outdoor lighting switch is connected. Thus, the light emitter 4 is turned on only when the main power switch 14 and the existing outdoor lighting switch are turned on, and the light emitter 4 is turned off when any one of them is turned off.

FIG. 6 is a schematic diagram showing the circuit configuration. In FIG. 6, 15 is a battery, 16 is a small lamp such as a vehicle side light and a tail light as outdoor lighting, 17 is the head lamp, and 18 is a switch for those outdoor lights. The body 4 is connected to the battery 15 via its switch 18 and a dedicated main power switch 14. Therefore, in the vehicle lighting device according to the present embodiment, the luminous body 4 does not turn on simply by turning on the main power switch 14, and the small lamp 16 is turned off when the engine is stopped and the vehicle is alighted while the vehicle is turned off. If the user forgets, the existing buzzer or the like emits an alarm sound, so that the light emitting element 4 is not forgotten to be turned off, and so-called battery discharge does not occur.

Since the existing outdoor lighting switch 18 has a circuit configuration in which the small lamp 16 is turned on even when the headlamp 17 is turned on, the light emitter 4 is not only turned on when the small lamp 16 is turned on. Even when the headlamp 17 is turned on, it can be turned on by operating the main power switch 14.

Here, the operation of the illumination device of the present invention configured as described above will be described. This illumination device is used, for example, when putting in a garage at night or traveling on a narrow alley. In use, it is sufficient to turn on the dedicated main power switch 14 with the small lamp 16 or the headlamp 17 turned on, which turns on the light emitter 4 and illuminates it from the rear of the vehicle body toward the lower left side thereof. Light will be irradiated.

[0021] Therefore, when entering the garage in the back, for example, it is possible to clearly see if there is an obstacle on the left side with the back mirror, and when traveling on a narrow alley at night, the vehicle is too close to the shoulder. It is possible to prevent derailing by traveling while checking whether or not there is a wheel.

Although the application example of the present invention has been described above, the vehicle lighting device according to the present invention is not limited to the above-described configuration. For example, the illuminator body 3 can be mounted not only on the passenger seat side but also on the driver seat side. It may be installed. Further, the light-emitting body 4 may not be linked with the small lamp 16 but may be turned on / off independently by only the main power switch 14. In addition, a chip type LED, a small incandescent light bulb, or the like can be used as the light emitting body 4.

On the other hand, the structure of the illuminator main body 3 may be, for example, an embodiment as shown in FIG. Here, the outer body 6 and the lens 7 are screw-coupled, and the lens 7 is formed larger than the outer diameter of the outer body 6 with its periphery being a flange 7A. Then, the illuminator body 3 of the present embodiment is fixed by sandwiching the peripheral edge of the mounting hole 8 formed in the body part between the outer body 6 and the lens 7. In this example, it is preferable to provide a ring-shaped gasket 19 at the flange 7A of the lens 7 to prevent rainwater or the like from entering.

[0024]

[Effect of the invention]

 As is clear from the above description, according to the present invention, the illuminator body attached to the rear side of the vehicle body is included, and the illuminator mounted on the illuminator body is used to locally illuminate the side area of the rear part of the vehicle body. This makes it possible to clearly see the rear side outside the vehicle from the driver's seat with a mirror even at night. As a result, it is possible to prevent the rear portion of the side of the vehicle body from hitting an obstacle or getting out of a wheel while traveling on a narrow alley, for example, when entering a garage.

[0025] Further, since the lighting of the light emitter can be performed by the operation switch in the vehicle, the ON / OFF operation can be performed quickly and easily as needed. The main power switch and other existing outdoor lighting switches are used together, and the illuminator is turned on when both switches are turned on, so that the battery can be prevented from running out due to forgetting to turn off the illuminator.

Further, since the illuminator body has a simple structure including an outer body having a built-in luminous body and a lens fixed to one end thereof, the illuminator can be provided at low cost, and a high-brightness LED is used as the luminous body. Since it is used, it can be made small and sufficient brightness can be obtained.
