Abstract

PROBLEM TO BE SOLVED: To provide the light ceiling which is easily assembled and has high design as if a single ceiling surface emits the light by constituting lighting plates and frames to support the lighting plates out of the same construction material, and making the whole ceiling surface shine by a lighting means. SOLUTION: Lighting frames 9 are formed in an inverse T shape, and are fastened to a lighting case 2 installed on the main ceiling 1. In lighting plates 10 on both sides, the three sides are supported by the lighting frames 9, and a lighting plate 11 is formed as an installing part to form a doorway to a rescue port 7 by dislocating it sideways after being raised upward at rescue time. A connecting part of the lighting plates 10 and 11 is supported by a stepped structure so that the light does not leak. In a lamp, not only straight tube type lamps 12 are longitudinally arranged but also two straight tube type lamps 12 are arranged in the lateral direction, and light nonuniformity-reduced more uniform whole surface light emission can be obtained. Since the same material is used in the lighting frames 9 and the lighting plates 10 and 11, a lighting system whose light passes through even lower parts of the lighting frames 9 and which has the lighting plates of whole surface light emission can be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting system for an elevator cab.

[0002]

2. Description of the Related Art Conventional cab lighting of an elevator will be described with reference to FIGS.

A cab lighting device mainly comprising a lighting plate of an elevator is provided with two or more milky white colors in a vertical and horizontal inverted T-shaped metal lighting frame 3 fastened to a steel lighting case 2 attached to a main ceiling 1. Of the lighting plate 4 and the lighting frame 3 from the main ceiling 1
In the case, the circular fluorescent lamp 6 is located above each lighting plate 4 in the case, and one of the lighting plates 4 corresponding to the rescue exit 7 required by the regulations of the elevator on the main ceiling is required. It is configured so that it can be removed as needed. In the lighting device configured as described above, the metal lighting frame enters the vertical and horizontal directions, so that the metal lighting frame is first seen and becomes a general lighting device that does not remain in the passenger's impression.

[0004]

A milky white acrylic light ceiling, which is provided with such a metal lighting frame provided vertically and horizontally and divided into whole surfaces, first has a metal lighting frame attached to the main ceiling during assembly. After the mounting and fixing, the lighting plate is mounted on the lighting frame. The mounting position of the lighting frame must be accurately determined, and the process is desirably shorter. Further, a shadow due to the illumination frame is generated, and the appearance is not good. Therefore, a ceiling where the entire lighting part (light ceiling) shines is desirable.

However, the conventional optical ceiling has the above-described configuration (divided by the illumination frame) for the following reason.

[0006] The lighting frame is for reinforcement, and it is necessary to provide a rescue exit at the center of the ceiling (as stipulated by regulations). This is because the entrance to the rescue exit 7 must be formed. For this reason, it is difficult to configure the light ceiling with one large lighting plate.

Accordingly, the present invention reduces or eliminates a metal lighting frame portion to facilitate assembly, and comprises only a lighting frame made of acrylic or the like which transmits light.
It is desired to obtain a high-designed light ceiling that gives passengers the feeling that one ceiling surface emits light.

[0008]

In place of the metal frame, a frame made of the same material as the lighting plate is formed, and the divided lighting plate and the shape of its peripheral edge are also changed so that adjacent lighting plates are connected to each other. It is constructed so that it does not rely on the strength of the lighting plate for the reinforcement frame. In this way, the frame is made as simple and light as possible so as to improve the light transmittance as a whole.

[0009] When not only the outer periphery of the light ceiling is supported by the illumination frame but also the intermediate illumination plate is supported by a support frame different from the illumination frame, the upper part of the support frame located above the illumination plate may be used. Is made of a transparent plate and the lower part is made of the same material as the lighting plate, so that the light emission over the entire lighting plate is made more uniform.

[0010]

Embodiments of the present invention will be described.

Embodiment 1 (FIG. 1 to FIG.
The lighting frame 9 is fixed to the ceiling 1 to the lighting case 2 and supports only the outer periphery of the lighting plate, and the lighting plates 10, 11, 10,.
It comprises a straight tube lamp 12 mounted vertically and a straight tube lamp 13 mounted horizontally.

The lighting frame 9 is fastened to the lighting case 2 in an inverted T shape. The three sides of the lighting plates 10 and 10 are supported on the lighting frame 9 by stepped portions, and the lighting plate 11 is positioned below the rescue exit 7.

FIG. 3 shows the configuration of the mounting portion of the fixed lighting plate 10 and the lighting plate 11 to be removed at the time of rescue. That is, the illuminating plates 10 and 10 on both sides are supported by the illuminating frame 9 on three sides thereof, and the illuminating plate 11 is raised and shifted sideways during rescue to form an entrance to the rescue exit 7. The connecting portion of the lighting plate is supported by a stepped structure so as to prevent light leakage.

[0014] With regard to the arrangement of the lamps, only the straight tube type lamps 12 arranged vertically have darkened portions of the lamp holder, so that the entire lighting plate does not have the same brightness. By arranging two straight tube lamps 13 in the horizontal direction, the entire lighting plate is made to have the same brightness, and more uniform light emission with less light unevenness is obtained.

Further, the lighting case 2, the lighting frame 9, and the lighting plates 10 and 11 may be made of the same material to further enhance the lighting effect. By using the same material for the illumination frame and the illumination plate, a lighting device having an illumination plate that allows light to pass through the lower portion of the illumination frame and emits light over the entire surface is obtained. The ceiling is a full-surface light ceiling where the light looks the same everywhere, and when viewed from below, the metal surface is not visible, resulting in a soft car illuminator.

Embodiment 2 (FIGS. 4 to 7 correspond to claim 3) The illumination plate 13 and the illumination frame 9 are made of the same material, and the surface of the illumination plate 13 is made uneven. That is, the lighting case 2,
The lower part 16 of the supporting frame 14, that is, the supporting frame that supports the lighting plate located between the lighting frame 9 and the lighting plate 13, is made of the same material.

The lighting plate 13 is fastened to the lighting case 2 with screws.

The support frame 14 is formed by polymerizing and bonding a lower opaque acrylic 16 to an upper transparent acryl 15.

The supporting frame 14 for connecting the lighting plates is formed in such a shape that the connecting portion is the same as the unevenness of the adjacent lighting plates 13 and 13.

That is, the convex portion 16 of the support frame has the same a-height as the groove having the same b-depth as the unevenness of the illuminating plate 13, and has a d-width equal to the width c of the convex portion of the illuminating plate. It is shaped like a letter, and when connected, the seams are difficult to understand, as if it were composed of a single lighting plate.

The upper portion of the support frame 14 is made of transparent acrylic and transmits light as it is, so that it does not become a shadow. Since both ends of the support frame 14 are connected to the illumination case 2 by screws (FIG. 7) and also serve as a reinforcement frame, a large full-surface illumination plate can be formed.

As described above, since the illumination frame and the support frame are made of the same material and the illumination frame and the support frame also serve as a part of the illumination plate, the assembly of the illumination plate can be performed simultaneously with the assembly of the frame. In other words, the positioning of the frame is unnecessary, and the assembly is easy because the material is the same. become.

Embodiment 3 A light control device and a calendar timer are mounted on a straight tube lamp mounted on a lighting device.

Dimming is performed by a calendar timer to change the brightness of the lamp. For example, the atmosphere can be changed by setting the brightness to normal during the daytime and lowering the brightness from the daytime in the evening.

[0025]

According to the present invention, there is no metal illumination frame on the surface, or the surface of the illumination plate is invisible by the grooved design of the irregularities, and the seam line is not visible, and the entire surface is formed by using the same material. Is a light ceiling that provides uniform light emission, and an illuminating device with high design properties can be obtained. Further, since the materials are of the same quality, the assembly is easy and the assembly time is shortened.
