ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a car cabin light device, more particular to a car cabin light device capable of illumining the car cabin and storing digital data such as a daily maintenance message for the car, speech or audio/video data.
2. Description of the Prior Art
A car cabin light is usually constructed by an incandescent bulb or a fluorescent lamp. However, the lifetime for such a conventional incandescent bulb is at most some one hundred to one thousand hours and thus a replacement of bulb is required frequently. Such a replacement is particular troublesome if the bulb to be replaced is located in a complicated mechanism or a convert place.
Moreover, a car audio system tends toward using optical disk play system. For complying to the use of such an audio system, a space in the car for storing the disk not to be played is necessary. However, such a space is hardly serviceable for other uses in case if no disks are to be stored.
Furthermore, as the world progresses, new styles of management are promoted. Management of car driving data, car maintenance data, or car service data are also demanded. To comply with such a demand, car driving data can be recorded by a car engine management computer and thus could be carried along with the car. However, the maintenance data or the service data is usually recorded in a computer at a car service center and thus could not be carried along with the car and once the service center for the car is changed, such a service data can not be continued to be utilized as reference.
SUMMARY OF THE INVENTION
Therefore, the object of this invention is to provide a car cabin light device capable of storing digital data and lighting the cabin. The digital data can concern car messages or relate to any video or audio data. The light device can be located in any place of the car which needs not to be spotlighted.
To achieve the above object, the car cabin light device according to this invention comprises a switch for turning the light on/off, a light emitting element for emitting light under a bias of an external source, and a socket provided in a car cabin for detachably receiving the light emitting element and conducting the external source thereto. The present invention is characterized in that the light emitting element is constructed by a luminous disk having a first surface for accessing data and a second surface for luminescing, and that the luminous disk comprises:
a data recording lamination located at the side of first surface for storing digital data;
a light emitting lamination having two side planes and located at the side of second surface; and
a biasing lamination for receiving and applying the external source onto the two side planes of the light emitting lamination for emitting light.
By means of the above mentioned design, a longer lifetime of the car cabin light, a more modifiable light shape, as well as a more gentle light will be available. Moreover, since one side of the light emitting element can be used to store/read digital data, the light emitting element could be used as a medium for storing a maintenance or service records or messages when it is taken from the socket. In contrast, the medium for storing data could be received in the socket to serve as a car cabin light when it is not used to store data or to play music, and thus solving the storage space problem of the medium. Furthermore, the maintenance or service records could be continued even though the service center is temperately changed because of the benefit of carrying the storage medium in the car without increased storage space needed.
These and other objects, features and advantages of this invention will be apparent from the following more particular description of the preferred embodiments of this invention as illustrated in the accompanying drawings.
