This invention relates to the improvement of the lighting apparatus installed in an elevator car (hereinafter referred to as a car).

Because the interior of the car is a narrow backroom, passengers often feel anxious or frustrated from the backroom.

In particular, the recent increase in skyscrapers and other driving time is long, or when the full load is added to the discomfort, so the improvement is desired.

However, in the ceiling which has the greatest influence on the car's tightness, the conventional monotonous lighting device is installed.

Referring to the conventional lighting apparatus based on the internal structure diagram of the elevator of FIG. 7, the lighting plate 3 disposed on the ceiling plate 2 of the car 1 is provided with a plurality of light sources 4, for example, a small bulb or a fluorescent lamp. Filter (6), for example, a transparent plate filter, a half mirror plate filter, or a filter plate having the injection inertia emitted from the light source 4 and installed on the ceiling cosmetic frame 5, 1) The inside of the car 1 is irradiated by induction of internal content.

In this case, the luminous intensity of the light source 4 is usually selected to give a predetermined illuminance in the car 1, that is to say to give a predetermined illuminance in the car 1, that is, of the practical range of recognition of an object in the car 1. The illuminance is set for the purpose.

In the conventional car lighting apparatus as described above, since the emitted light passes through the filter 6 from a small bulb, which is the light source 4, the light source is lowered in brightness and color, and further changes color as white light or white light or monochromatic light. There is no attraction for the passenger's sight.

Therefore, the emergence of a lighting device that can be a more changing lighting is desired.

In addition, if a light source using filament, for example, a light bulb, is used for the light source 4, the area of the light source 4 is narrow, so that a large number of light bulbs need to be scattered and installed in order to achieve the lighting effect on the entire ceiling surface. There was a problem because of the cost.

The present invention aims to solve such a problem, and aims to provide a lighting device in an elevator car of a simple configuration that can solve the anxiety or discomfort of passengers, and can make attractive lighting rich in changes in the car.

The car lighting apparatus according to the present invention is provided with a light source that emits composite light, and a spectral decomposition filter is installed between the light source and the inside of the car.

In this design, since the spectral decomposition filter spectrally decomposes the emitted light from the light source due to the diffraction phenomenon of the light beam, the illumination light illuminating the car becomes spectral light and becomes attractive.

It demonstrates, referring drawings for one embodiment of this invention.

In addition, the same code | symbol as FIG. 7 (a conventional example) represents the same or an equivalent part.

In FIG. 1, FIG. 6 is a spectral decomposition filter, and this spectral decomposition filter 6 is fixed or mounted on the affinity cosmetic frame 5. As shown in FIG.

The injection inertia, which is a composite light emitted from the light source 4, is guided into the car 1 through this spectral decomposition filter 6 to illuminate the inside of the car 1.

7 is the spectral broadness which the emitted light which spectrally decomposed with the spectral decomposition filter 6 portrays on the surface inside the car 1 of the spectral decomposition filter 6.

Here, the spectral decomposition filter 6 will be described with reference to FIGS. 2A and 2B.

The spectral decomposition filter 6 in FIG. 2a performs spectral decomposition using a diffraction phenomenon of light. For example, one side of the translucent plate 6a using a transparent resin plate becomes matt and the width (a) is weak. A 10-micrometer line A and the stripe-shaped diffraction grating 6b which become a 10-micrometer line B with transparent width b are formed. When white light is applied to the spectral decomposition filter 6, the white light is decomposed into a spectrum to form a beautiful spectrum.

This spectrum is obtained by spectroscopy in a direction parallel to the stripe pattern of the diffraction force difference 6b. FIG. 2B shows a light source on the lower surface side of the spectral decomposition filter 6, which is parallel to the pattern of the diffraction grating on the upper surface side of the spectral decomposition filter 6 by diffraction when white light is emitted upward from the lower surface side. The case where the linear spectrum light band 7 with the especially bright part 6c of the top of a light source position is formed is shown.

3a and b are equivalent degrees to 2a and b, respectively, and show the case where the diffraction gap 6b is formed in the shape of a lattice stripe.

At this time, when white light is emitted upward from the lower surface side of the spectral decomposition filter 6 as shown in FIG. 2B, a + -shaped spectral band centered around the particularly bright part 6c of the position of the light source in response to the grid pattern of the diffraction grating ( 7) form.

Such a spectral decomposition filter 6 is already known and commercially available.

In addition, 2a, b and 3a, b are detailed views, respectively, partially omitted. Therefore, when the interior of the car 1 is illuminated through the spectral decomposition filter 6 as described above, the passengers of the elevator can see the emitted light from the light source 4 as the light source obtained by spectrally decomposing the illumination in the car 1. The brightness and color can be very attractive lighting.

In addition, when the light source 4 is a point light source such as a bulb, the spectral light formed by the spectral decomposition filter 6 appears to be long in the shape of a band by the width of the point light source, so increasing the brightness of the entire ceiling can reduce the light bulb. This can significantly reduce costs.

FIG. 4 shows the embodiment of FIG. 2 in which a half mirror tube 8 is placed on the spectral decomposition filter 6 with the illumination plate 3 as a mirror.

Then, the light emitted from the light source 4 installed on the lighting plate 3 reflects between the lighting plate 3 and the half mirror tube 8, which are mirrors, so that the half mirror tube 8 is placed on the lighting plate 3 as well. The reflected light source 4 forms an image and the spectral light 7a forms an image. Therefore, it is possible to make a very luxurious lighting device.

FIG. 5 also shows a third embodiment, in which a mirror ball 9, which is rotated by the motor 10, is installed on the ceiling plate 2, and the same is installed on the ceiling plate 2, Similarly, when the reflected light emitted from the light projector 11, which is a light source fixed to the ceiling plate 2, is reflected by the mirror ball 9 and reflected on the spectral decomposition filter 6, the mirror ball 9 is rotated. The mirror ball 9 becomes a moving light source, which can produce a dynamic lighting effect by the movement of the spectral light and the polymerization of the light rays of the light source.

FIG. 6 shows the fourth embodiment, in which the bulbs 4a are provided at the tip of the plurality of three-dimensionally arranged bulb holders 12 attached to the ceiling plate 2, the bulb holders 12 and the bulbs. The passenger can see the spectral band 7 from the side as if the 4a is wrapped with the hemispherical spectral decomposition filter 6a.

In each of the above embodiments, the case where the lighting device is in the ceiling of a car has been described, but the present invention is not limited to the ceiling. For example, the above-described effect can be obtained even when the lighting device is provided on the side wall.

As described above, the present invention provides a simple configuration in which a spectral decomposition filter is installed at a time between the plurality of light sources emitting light and the interior of the car, thereby spectrally separating the emitted light from the light source to improve the brightness and color of the lighting in the car. We can perform decorative lighting full of change.

In addition, the spectral light has the property of spreading, so that the brightness of the entire ceiling surface can be increased, so that it is possible to perform bright lighting with a small light source (light bulb), to manufacture at a low cost, and to simplify the overall configuration of the lighting device. It is possible to perform ordinary lighting.
