Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device used in a vehicle or the like, and more particularly to a lighting device using a light bulb used in a vehicle light.

[0002]

2. Description of the Related Art Conventionally, by illuminating the interior of a vehicle such as a private car, passengers can easily get on and off at night,
In-vehicle lighting is also used to make it possible to read maps and the like in the dark. This lighting is called a vehicle interior light, and is provided near the ceiling inside the vehicle (in the passenger compartment), and is turned on and off by opening / closing the vehicle door or a dedicated switch. As a modified example, the illumination is removed from the ceiling so that it can be illuminated at any place within the reach of the power cord (electric wire) (for example, see Japanese Utility Model Laid-Open No. 59-35242).
Or those which are detachably attached to the socket of the cigarette lighter (for example, the actual open Sho 62-131941
In addition, there is a system in which the power cord is extended to illuminate the outside of the vehicle (outside the vehicle), the inside of the engine room, or the like other than the inside of the vehicle.

[0003]

By the way, in the above-mentioned conventional lighting fixture, the light source used for the light emission (illumination) is a dedicated light bulb (mainly an incandescent bulb), and the illuminance can be adjusted. Most are not. The reason for using the dedicated light bulb is that it is advantageous in making the lighting thinner and smaller in size, and because the illuminance is kept low. The reason why the illuminance cannot be adjusted is that the incandescent bulb requires a high current, which makes the control circuit complicated and expensive, and simply uses resistors to disperse the voltage or uses a shield hood. It can be said that the main reason is to promote fever unnecessarily.

Due to the inability to adjust the illuminance, the interior light is appropriately darkened from the viewpoint of preventing dazzling at night (a phenomenon in which a dark place makes it difficult to see a dark place due to a pupil closing due to bright light). Is installed. Therefore, when it is desired to have appropriate brightness such as when checking fine characters on a map or the like, separate bright lighting must be prepared.

On the other hand, a vehicle light (or a vehicle light, which is hereinafter used as a synonym for a light and a light) transmits information that is extremely important in the operation of the vehicle, such as direction indication and braking operation, to other vehicles,
It is an indispensable light to carry out safe operation. Therefore, if some of the vehicle lights do not light (unlight),
It cannot be operated as a damaged vehicle. It is not hard to imagine that if you drive unreasonably, it will lead to a serious accident. Most of the causes of non-lighting of vehicle lights are bulb failures, that is, bulb burnout (broken filaments or other major components of the bulb), and therefore can be restored by replacing the bulb. . However, the light bulbs unique to each vehicle are
It requires a repair facility. Then, the vehicle cannot be moved until the light bulb is available.

In view of the above, the first object of the present invention is to provide a vehicle lighting device with a function as a spare light bulb storage place for vehicle lights, and to provide an illuminance adjusting function by a simple means.
