Description

The present invention relates to a display system installed near an entrance / exit of a vehicle such as a bus, a building, or the like or outside the entrance / exit.

In the night or on dark days, if the entrance of a building or the entrance of a car such as a bus is illuminated, the existence of the entrance can be understood immediately, and even an elderly person can safely enter and exit. If a welcome word or advertising text is displayed on the screen, it will relieve the heart of those who use the doorway and promote advertising.

Conventionally, for example, there is an invention of an open / close switch as disclosed in Technical Document 1 as illumination means for a vehicle entrance / exit. There is (Patent Document 2) that uses this seal part as a light source and guides it to a push button via a light guide to illuminate the display. There is an invention (Patent Document 3) in which an advertisement part that can be visually recognized from the outside is provided on the vehicle ceiling, and the advertisement part can be visually recognized at night.

However, even though these conventional technologies illuminate the entrance / exit portion, there has been no invention or device for simultaneously illuminating the road surface outside the entrance / exit.

Problems to be solved by the invention

Therefore, the purpose of this plan is at the entrance of a building or the entrance of a vehicle, and it is possible to find the entrance immediately even at night or on dark days. As a result, the entrance system that can safely enter and exit and the display system installed in the vicinity Is to provide. Moreover, at the entrance and the vicinity, it is possible to draw words that call attention when entering and exiting, promotional characters such as the company name of the provider and the logo of the product, and characters that are used frequently such as welcome and the like It is to provide a display system installed in the vicinity.

Means for solving the problem

Thus, the features of the entrance and exit display systems using the proposed lighting fixtures are characterized by the fact that they are mounted on the ceiling of the entrance / exit at the entrance of a vehicle such as a bus or the entrance of a building, or on the side of the entrance / exit. In addition, a light source including one or more semiconductor light emitting elements that can irradiate a road surface outside the entrance and the like is provided.

In addition, the irradiation light from the semiconductor light emitting element can irradiate the surface of the entrance / exit, the staircase portion, the surface outside the entrance / exit, etc., through a reflecting mirror attached to an appropriate position such as a vehicle such as a bus or a building. This is also a feature.

Subsequently, the semiconductor light emitting device is housed in a plurality of casings that are not one, and the casing can be turned around the mounting position of a vehicle such as a bus or a building as a fulcrum. It is also characterized in that a polarizing lens and an optical filter are disposed in the end portion of the casing, and a polarizing lens and an optical filter are arranged in the casing in the irradiation direction of the semiconductor light emitting element.

It is also characterized by having a transparent or translucent translucent member provided so as to cover the light emitting surface side of the light source and on which appropriate characters and figures are drawn.

When the present plan is implemented, it is preferable that the light source is a combination of three semiconductor light emitting elements that emit red, green, and blue, which are the three primary colors of light.

The invention's effect

And the light from the light source in this proposal is at the entrance of cars such as buses and entrances of buildings, etc. so that it can illuminate the surface of the entrance, the staircase, the outside road surface, etc. Such an entrance can be found immediately, and since the entrance is illuminated, it is safe to enter and exit.

And on this irradiated part, you can draw words that call attention with a translucent translucent material, promotional characters such as the company name of the provider and product logo mark, and welcoming characters such as welcome It was.

As an example of the present invention, the case where the present invention is applied to a car (1) such as a bus as shown in FIG. (2) is an entrance / exit of the automobile (1), and (3) is a road surface outside the vehicle near the entrance / exit (2).

In addition, (4) is an LED that is attached to the ceiling of the automobile (1) or its side surface, and can irradiate the surface of the entrance (2), the staircase, the road surface (3) outside the automobile, etc. These are a plurality of casings arranged in a cylindrical cover (5) having a light source as described above. An example of the configuration of the casing (4) is shown in FIG. That is, in the drawing, three cylindrical casings (4) are combined adjacent to each other and stored in the cover (5).

In the casing (4), one to several LEDs (6) are provided at one end thereof. A bent lens (7) is provided concentrically around the periphery. The bent lens (7) is for irradiating all the light emitted from the LED (6) around it in one horizontal direction.

Furthermore, (8) is a transparent or translucent translucent member on which characters and figures are drawn in correspondence with the irradiation direction of the LED (6) and at intervals. Further, (9) is a lens corresponding to the translucent member (8) and arranged at an interval, and (10) is a reflecting mirror arranged at an interval corresponding to the lens (9). is there.

Further, although not shown or described in detail, each casing (4) has, for example, three sliding casings (11) in which the cylindrical casing (4) can slide in the central direction along the axis as shown in FIG. With (12) and (13), it is possible to easily focus images, graphics, and characters on the entrance (2) of the automobile (1) and the general road surface (3) that follows this.

FIG. 7 shows another embodiment of the casing (4). It is provided with a portion (14) where the LED (6) and the bent lens (7) are arranged in contact with the inner wall of one end of the casing (4), and then two strips are provided on the inner peripheral surface of the casing (4). There is a protruding groove (15) for fitting a transparent or translucent translucent member (8) on which the above characters and figures are drawn.

That is, the translucent member (8) is always changed in characters and figures drawn on it. For this purpose, a large number of translucent members (8) on which a number of different characters and figures are drawn in advance are prepared, and the translucent member (8) can be freely inserted into the protruding groove (15) from the outside of the casing (4). It is preferable that it can be easily replaced.

Further, (16) is a lens protrusion groove of the lens (7) similar to the protrusion groove (15), and (17) is a similar mirror protrusion groove of the reflecting mirror (10). As described above, each member of the present plan has only to be fitted into the respective protruding groove, and the assembly thereof is easy.

The provision of the three casings (4) in the cover (5) means, for example, that one of them has a bright background for irradiating the entrance / exit (2) and the road surface (3) in the automobile (1). The other one is superimposed on the irradiation part of the casing (4), and “Welcome”, other advertising characters, and a different color from the above, and the other one Irradiates a general road surface (3) following the doorway (2) of the car (1) with a pattern or color of an appropriate shape to display the presence of the doorway (2) of the car (1). .

The light emitted from each casing (4) is not limited to the above, and the light-transmitting member (5) that emits the three primary colors of light, red, green, and blue, can be freely emitted by three colored LEDs (6) that emit light. It can also be a combination of various colors.

As described above, the light from the casing (4) of the present invention is in a car (1) such as a bus so that it can irradiate the surface of the entrance (2), the stairs, the road surface (3) outside the car, etc. Therefore, the entrance / exit (2) of the car (1) such as a bus such as a night or dark day can be found immediately, and since the entrance / exit (2) is illuminated, it can be safely in / out.

Moreover, on the irradiated portion, a translucent translucent member (5) is used to draw words that call attention, promotional characters such as the company name of the provider and the logo of the product, and characters used for welcoming purposes. It was possible.
