Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a ceiling lighting device installed in an elevator car.

[Prior art] Conventionally, ceiling lighting devices installed in elevator cabs are
Figure 3 shows the entrance of the Noveta cage (1) as if it were a child.
A light source (5), for example, a fluorescent light, is added to the lighting case (3) placed in the well (2), and the light (6) emitted from this light source (5) is sent to the elevator car through the globe (4).
(1) and illuminates the inside of the elevator car (1). In this case, the brightness of the light source (5) is usually selected so as to provide a predetermined illuminance in the elevator car (1), which is of practical use for recognizing objects in the elevator car (1). The brightness is set to the target.

However, the Tenkawa lighting device shown in Figure 3 can refract the transmitted light even if the surface of the globe (4) is made uneven, but the refraction angle remains at a predetermined value and does not change. , Also, the globe (4) is a medium color and the color changes 17), so the outlook 111. Hotel III'S
It may be that it is inappropriate for the atmosphere of the place where it is used. People 1.1: ! Because you can get variable lighting. −
! The parent device of the I'I bright device is desired.

Therefore, a lighting device described in Japanese Utility Model Publication No. 53-2481 t'f has been proposed, but this lighting device requires a complicated circuit configuration, which results in an increase in cost.

[Summary of the Invention] The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a lighting device for an elevator cabin, which has a tubular configuration and is capable of illuminating the elevator cabin in a variety of ways. The outline of the present invention for achieving such an object is to arrange a container formed of a light-transmitting member in a lighting case placed on the ceiling of an elevator room, It is characterized by containing a colored or non-colored liquid therein, and further containing a light dispersing material in the oil body, if desired.

[Embodiment of the Invention] An embodiment of the invention will be described with reference to the drawings. Incidentally, the same members as those in FIG. 3 are given the same reference numerals 'I' and their explanations will be omitted.

In Figure 1, (7)° is a container, and this container (7) is
It is made of a light-transmitting member and is placed inside the lighting case (3).
=The container (7) is placed so as to cover the bottom surface of the open part of (2). Inside this container (7) is a liquid (8).
For example, to contain water. The oil in the liquid (8) contained in this container (7) may be smaller than the volume of this container (7), for example. When l+) of the liquid (8) is made smaller than the volume of this container (7), the fluctuating surface of the liquid (8) makes it possible to provide a variety of illumination inside the elevator car (1). It is from.

When the ceiling lighting device is configured as shown in Fig. 1, the light (6) emitted from the light source (5) placed on one side of the container (7) passes through the container (7) and the liquid (8). Will it reach the inside of the elevator car (1) and illuminate the interior of the elevator car (1)?
- Evening 1 - The vibrations caused by the movement of the container (
Since the liquid (8) in the chamber (7) oscillates, it is possible to provide illumination with rich variations in brightness and darkness within the car room (1).

The liquid (8) shown in Figure 1 is colorless and transparent;
The k body (8) may be colored +1' or pink with 78 colors. When the liquid (8) is colored, it is possible to further change the shade of color within the elevator car (1) due to the fluctuation of the liquid level.

Further, as shown in FIG. 2, a light dispersing material such as aluminum pieces (aluminum J!') (9) may be dispersed in the liquid (8).

The aluminum pieces (9) are dispersed in the liquid (8) (and the fluctuation of the liquid level causes the aluminum pieces (9) to be dispersed in the liquid (8).
Coupled with the rocking of the liquid (8), the light incident on the liquid (8) is reflected by the aluminum piece (9), and the light enters the elevator car (1) in various directions C8A), (8B),
(BG), and as a result, the inside of the elevator car (1) can be illuminated with random and wide variations in brightness and darkness. Furthermore, by dispersing Aluminum L and pieces (8) in the 11-colored liquid (8), in addition to changes in brightness and darkness, lighting with rich color changes and C# changes can be created in the elevator car room (1). can do.

The same effect as described above can be obtained by using the aluminum pieces (!3), (7), and other colored transparent filters 1 as the light dispersion material.

Furthermore, this container (7) may be made into a closed container, and a kind of liquid which is incompatible with different ratios and which is colored may be replenished into this closed container.

In this way, the interface of the -1 type of liquid will oscillate, and the elevator can illuminate the interior of the room (1) with a rich variety of illumination due to the light passing through this interface.

In the above description, the shaking of the liquid is caused by vibrations caused by the operation of the elevator, but the container may be forcefully shaken by a mechanical structure such as a motor, a crank, or the like.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide lighting inside an elevator car with a variety of brightness changes, color changes, and color shading changes. Moreover, the ceiling lighting device according to the present invention has an extremely simple configuration, as it only requires placing a container containing a liquid inside the lighting case.
It can be an inexpensive lighting device.
