Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a display device that emits light and is used by being directly attached to a window glass such as a rear window of an automobile.

[Conventional example]

Conventionally, there have been no light-emitting display devices that are used by being directly attached to window glass. Even if there was a device with such a construction, it is presumed that the mounting location was specified.

[Problem that the invention attempts to solve]

In general, display devices that use light emitting light have a fixed position at the time of installation, and not only cannot they be moved to any desired position, but also cannot be removed immediately without leaving any traces when unnecessary. The problem is that it cannot be done. Another problem is that once the set position is fixed, the display state cannot be changed arbitrarily.

[Means for Solving the Problems] As a specific means for solving the above-mentioned problems, the present invention forms a suction cup portion having a lens function using transparent or semi-transparent and heat-resistant rubber as a material, and A display device for an automobile is characterized in that a cylindrical light source insertion part is integrally formed approximately at the center of the back side of a panel part, and a large number of concentric lens cuts are made over the entire back side. It is intended to provide
Since the suction cup part can be attached directly to glass such as the rear window of an automobile by suction, the installation location can be changed easily and arbitrarily.

〔Example〕

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a suction cup part, and a cylindrical light source insertion part 2 is integrally formed approximately at the center of the back side of the suction cup part. The material used in this case is an elastic rubber material that is transparent or translucent and has excellent heat resistance, and silicone rubber is preferred. The suction cup part 1 is formed in the shape of a suction cup with a curved concave surface on the entire surface side, and a large number of lens cuts 3 are provided on the back side in a substantially concentric manner. This lens cut 3 has a lens function so as to reflect the light from the light source inserted into the light source insertion part 2 to the front side.

The positional relationship between the suction cup part 1 and the light source insertion part 2 is such that the optical axis It is configured to be inclined within an angular range of approximately 40 degrees with respect to Y-Y.

Note that the reference numeral 4 is a light source such as a light emitting diode or an incandescent light bulb.

The display device configured in this way has, for example, a third
It is used as shown in FIG. That is, in FIG. 3, an incandescent light bulb with relatively high illuminance is used, and if the suction cup part 1 is attached to the rear window glass 6 of the automobile 5 by suction, it can be easily and stably installed. Can be installed in any position. In the illustrated case, two lights are used, and can be used as an auxiliary signal display light for stop or turn signals, for example.

In addition, in Fig. 4, the whole is formed small,
Using light emitting diodes as a light source, a large number of light emitting diodes are connected in parallel at appropriate intervals as shown in FIG. It is possible to do so. Then, by connecting the lead wire 7 taken out to the lead wire of the stop lamp, when the brake is stepped on, the stop lamp lights up and at the same time the illuminated letters ``STOP'' are displayed on the rear window. In this case, a red light emitting diode is naturally used. In short, by arbitrarily selecting the emitting color and using a large number of display devices connected in parallel, it is possible to display message characters or other appropriate signals.

[Effect of idea]

As explained above, the automobile display device according to the present invention has a suction cup part and a light source insertion part integrally formed with transparent or semi-transparent rubber, and furthermore, the suction cup part has a lens function. With this structure, it can be easily attached to a smooth glass surface using the suction cup, and the mounting position can be set at any location without any restrictions, without leaving any traces. It has the excellent effect of being able to be attached and removed.

Moreover, if a large number of the same display devices are connected in parallel and used, an excellent effect can be obtained in that any message character or signal can be displayed.
