[0003]

[Problems to be solved by the invention]

 The present invention has been made based on the above circumstances, and the purpose is to use a power source for a cigarette lighter to provide an interior lighting device equipped for interior lighting and a light to the outside of the vehicle. It is an object of the present invention to provide a vehicle interior lighting device that can incorporate a strobe lamp that emits a signal to perform functions such as notifying a parking position.

[0004]

[Means for Solving the Problems]

 For this reason, in the interior light device for a vehicle of the present invention, as is apparent from the illustrated embodiment, the interior 43 of the substantially single structure including the light emitting portion 4 of the interior light device for the vehicle is included. Further, a strobe lamp 41 that emits intermittent flash light and an illumination lamp 42 that emits light continuously are provided, and at least switch means 6 for switching between emission by the flash lamp 41 and emission by the illumination lamp 42 is provided.

The vehicle interior light device of the present invention includes a power plug 2 connected to a cigarette lighter power source 1 and supplies current to the light emitting unit 4 via a voltage converter 3. A strobe lamp 41 that emits intermittent flash light and an illumination lamp 42 that emits light continuously are provided in an enclosure 43 having a substantially single structure including the light emitting section 4, and at least the strobe lamp 41 and the illumination lamp are provided. A switch means 6 for switching the light emission of 42 is provided. Between the power plug 2 and the light emitting section 4, a flexible conductive cord 7 having strength for holding the light emitting section 4 is provided. It is characterized by being connected.

In this case, as an embodiment of the present invention, the illumination lamp 42 is constituted by an LED lamp or the like. The power plug 2 is provided with a voltage converter 3 and a switch means 6 on its plug body 21. The switch means 6 switches the light emission of the strobe lamp 41 and the illumination lamp 42, and simultaneously emits the light. The on / off switching of the power supply connection to the unit 4 is performed.

In such a configuration, the power plug 2 is inserted into the power supply 1 for the cigarette lighter, for example, in order to illuminate the driver's hand, the switch means 6 is turned from the off position to the position where the illumination lamp 42 is turned on. By switching, indoor lighting, especially lighting at hand in the driver's seat, can be achieved. Also, if the switch means 6 is switched to a position where the strobe lamp 41 is turned on during parking, the blinking light of the strobe lamp 41 is transmitted to the outside of the automobile through the window glass. By relying on this flashing light, it is possible to easily reach the parking position.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The interior light device for a vehicle in this embodiment has a power supply plug 2 connected to a power supply 1 for cigarette lighter and has a structure for supplying a current to a light emitting unit 4 via a voltage converter 3. In particular, in the envelope 43 of the light emitting unit 4, a strobe lamp 41 and an illumination lamp 42 such as an LED lamp emitting blue light are provided in parallel.

As shown in FIG. 2 (block diagram), between the voltage converter 3 and the light emitting unit 4, the light emission of the strobe lamp 41 and the illumination lamp 42 is switched, and the power supply connection to the light emitting unit 4 is established. It has switch means 6 for switching on and off.

In this embodiment, the power plug 2 has a plug connecting portion 22 at the distal end of a plug body 21, and a voltage converter 3 and a switch switching circuit are provided at a proximal end 23 thereof. 5 and the switching means 6 of the switching circuit 5 is provided at the base end of the plug body 21. The switch means 6 also serves as an on / off switch for power supply connection to the light emitting unit 4 in addition to the switching of the switching circuit 5 (ie, a three-stage switching operation mechanism).

In this embodiment, at least a part of the envelope 43 of the light-emitting unit 4 is transparent, and has a crane beak shape with a sharp tip in consideration of design. The light emitting unit 4 is connected to the light emitting unit 4 by a flexible conductive cord 7 having strength to hold the light emitting unit 4. The envelope 43 of the light emitting section 4 has a transparent light emitting section for transmitting the light of the strobe lamp 41 and the illumination lamp 42.

In such a configuration, the power plug 2 is inserted into the cigarette lighter power supply 1 and, for example, in order to illuminate the driver's hand, the switch means 6 is turned from the off position to a position where the illumination lamp 42 is turned on. When the switching is performed, the switching circuit 5 is switched, and the illumination lamp 42 is turned on by the power supplied from the power supply 1 via the voltage converter 3 so that the interior lighting such as the driver's hand can be performed. If the switch means 6 is switched to a position where the strobe lamp 41 is turned on during parking, the flashing light of the strobe lamp 41 is transmitted to outside of the vehicle through the window glass during parking. When returning, you can easily reach the parking position by relying on this flashing light. The light signal from the strobe can be used in other emergencies, with the attention of a third party outside the vehicle.

In this embodiment, a flexible, semi-rigid shield member capable of maintaining the state in a required shape is employed as a jacket of the conductive cord 7 to hold the light emitting section 4. However, the light emitting unit 4 may be installed at a required position in the vehicle interior by using a normal flexible conductive cord. In this case, it is necessary to separately provide a mounting means for holding the light emitting unit 4 at the required location. In addition, a blue light emitting LED lamp is used as the illumination lamp 42, but another light emitting color (red, green, etc.) may be used if necessary. As the illumination lamp 42, a normal miniature lamp (incandescent lamp) or the like can be used. Further, the switching circuit and its switch means may be made more multipolar so that a plurality of colors of strobe lamps or illumination lamps can be switched on for lighting, and lighting can be selected according to the application.

[Effect of the invention]

 In this way, according to the present invention, the function of the interior lamp is performed by the illumination lamp, and the flash light is emitted by the strobe when necessary, and the function of notifying the location of the vehicle to the outside by the emission signal is used. Can be demonstrated.

According to the present invention, in a structure in which a power plug is connected to a power source for a cigarette lighter and current is supplied to a light emitting unit, a voltage converter and switch means are provided in a plug body of the power plug, The operation of the switch means switches the light emission of the strobe lamp and the illumination lamp, and the power supply to the light-emitting unit is switched on and off, so that the entire device is compact and the operation of the switch means is fixed. It can be performed stably on the side of the power plug in the fixed position, which is effective in terms of safety of switching operation.
