Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a vehicle accessory case such as an automobile console box or a glove box, that is, a lighting accessory vehicle accessory case.

[0002]

2. Description of the Related Art Various types of small articles, which are box-shaped or pocket-shaped, are provided in the interior of an automobile. Then, for example, a console box is generally provided between the driver's seat and the passenger's seat so that various kinds of drive accessories, cassette tapes or the like can be stored therein. Further, particularly recently, in many cases, a cup holder for holding a canned beverage or the like is integrally or detachably provided in the console box.

By the way, at night, the interior of the vehicle is dark, and the interior of small items such as a console box is also dark. Therefore, when driving at night, it is difficult to remove or store small items from the small case,
In particular, it is very difficult to take in and take out canned beverages from the cup holder because the contents may be spilled. However, the interior of the vehicle can be brightened by turning on the interior light, but this is not preferable because the light is reflected on the window glass.

For this reason, there is already known an example in which an ashtray provided on the instrument panel is illuminated by attaching an illumination lamp to the upper wall of the storage portion of the instrument tray (for example, Japanese Utility Model No. 6). -1476 publication). There is also known an example in which an illumination lamp is attached to the inside of the glove box, and the inside of the glove box is illuminated when the glove box is opened by a switch that is switched by opening and closing the lamp (for example, Jikken 6-1476). Issue). And, in these examples, a bulb, that is, an incandescent lamp is used as the illumination lamp.

[0005]

As described above, in order to facilitate the handling at night, it is known that an ashtray or a glove box for automobiles is provided with an illumination lamp composed of an incandescent lamp to illuminate it. There is. Therefore, with regard to the console box as described above, in order to make it easy to put in and take out small items and canned beverages at night, an illumination lamp is attached to an appropriate place to illuminate and brighten the inside. It is possible.

However, when an ordinary incandescent lamp is used as the illuminating lamp as in the conventional case and this is simply attached to the wall surface of the console box, the light of the incandescent lamp is dispersed not only in the box but in the entire circumference, so that the lighting The light leaks to the place where there is no need, and it brightens the place unnecessarily.
Such a problem can be prevented by, for example, mounting the incandescent lamp sufficiently deep inside the wall surface of the console box. However, in this case, sufficient brightness cannot be obtained, and since the incandescent lamp has a large amount of heat generation, it cannot continue to be lit for a long time. Therefore, when an incandescent lamp is used, it is practically difficult to illuminate the inside of the console box with sufficient and appropriate brightness and prevent light from leaking to unnecessary places. That is.

Further, in the case of the incandescent lamp, since the amount of heat generated is large, not only the consumption current is increased when the lamp is lit for a long time, but also the life is short. Therefore, when an incandescent lamp is attached to a console box to form a lighting device, in order to control the lighting thereof, an electric switch or the like that switches depending on whether the lid is opened or closed, as in the example of the glove box described above, Required as a dedicated switch. Therefore, although the incandescent lamp itself is inexpensive, the cost of the lighting device as a whole is relatively high.

Further, among the accessory cases for vehicles, the console box is relatively often used for exchanging music tapes, and particularly when the cup holder is provided in the console box. Therefore, when illuminating such a small case, it is desirable that the illumination is always performed during nighttime driving, as in the case of instrument lighting. It is also possible to omit the dedicated switch by turning on the lights in conjunction with each other. However, for that purpose, it is important that the power (current) consumed for lighting is sufficiently small.

Therefore, the present invention has an object to provide a lighting device for a vehicle accessory case which can illuminate the interior of the vehicle accessory case with sufficient brightness and at a low power consumption. To do.

[0010]

The above-mentioned problems are basically solved by providing an illumination lamp using a light emitting diode, which has high luminous efficiency and therefore consumes less power, in a vehicle accessory case.

That is, a lighting device for a vehicle accessory according to a first aspect of the present invention comprises an accessory container provided inside a car and an illumination lamp which is attached to a wall surface of the accessory container and illuminates the inside of the accessory container. In an illumination device for a vehicle accessory case, the illumination lamp includes a lamp body having a mounting portion for a wall surface of the accessory case, and a light emitting diode assembled to the lamp body and including a plurality of light emitting diode chips to form a light emitting body. The module includes a module and a lens which covers the light emitting diode module and disperses light emitted from the light emitting diode chip inside the accessory case.

As described above, in this lighting device for a small container for a vehicle, the illumination lamp particularly includes a light emitting diode module that includes a plurality of light emitting diode chips to form a light emitting body, and light emitted from the light emitting diode chips. And a lens that disperses the inside of the accessory case. Therefore, the emitted light from the light emitting diode chips passes through the lens and is efficiently dispersed and distributed inside the vehicle accessory case. Therefore, by appropriately setting the number of the light emitting diode chips, small objects or It is possible to illuminate the inside of the small container only in a necessary range with a sufficient brightness and appropriate brightness for putting in and taking out canned beverages. In this case, since the light emitting diode chips form a point light source, it is possible to easily set a desired illumination range by appropriately arranging them and appropriately arranging lenses corresponding to them. Also, there is less fever,
Since the light emitting diode, which is a light emitting element having high light emitting efficiency, is used, it is possible to illuminate the vehicle accessory case with low power consumption.

Therefore, according to this lighting device for a small container for a vehicle, since the power consumption is small, the lighting lamp is directly connected to the electric circuit of the small lamp (clearance lamp), and the small lamp is turned on. It is possible to keep the lights on all night at night. And thereby, the switch for controlling the lighting of the illumination lamp can be omitted, and the illumination device can be formed at a lower cost.

That is, a lighting device for a vehicle accessory case according to a second aspect of the present invention is the lighting device according to the first aspect, wherein the illumination lamp is turned on in conjunction with turning on of the small lamp.
