Description

  The present invention relates to an elevator ceiling lighting device.

  15 is a longitudinal sectional view of a cab equipped with a conventional elevator ceiling lighting device, FIG. 16 is an enlarged sectional view of a main part of FIG. 15, and FIG. 17 is an exploded perspective view of the elevator ceiling lighting device of FIG.

  As shown in FIG. 15, the elevator ceiling lighting device 101 includes a lighting case 102 attached to a ceiling plate 202 of an elevator cab 201. The illumination case 102 has an open bottom surface, and an illumination plate 103 made of a light-transmitting material is attached substantially horizontally so as to cover the opening.

  As shown in FIGS. 16 and 17, a plurality of lamp holders 104 are fixed to the ceiling plate 202 with screws 105. The lamp holder 104 has a lamp holder 104 a that holds the annular light source 106 in a state of being spaced apart from the ceiling plate 202.

  Reference numeral 107 denotes a reflecting member, which is fixed together with the lamp holder 104 so as to be in contact with the ceiling plate 202 with a screw 105. The reflecting member 107 may be fixed to the ceiling board 202 with an adhesive. In some cases, instead of the reflecting member 107, the ceiling plate 202 is subjected to reflection processing so that the ceiling plate 201 also serves as the reflecting member.

  By installing the reflecting member 107 between the light source 106 and the ceiling plate 202, the light from the light source 106 is irradiated almost uniformly toward the entire surface of the lighting plate 103 to reduce unevenness of light, and the lighting device is excellent in design. Was realized.

  In recent years, elevators without machine rooms are becoming the mainstream, and in hoistways where the car room moves up and down, hoisting machines and sheaves are installed above the car room from elevators with machine rooms. There must also be a lot of placement.

  Since the total height of the hoistway cannot be increased due to building restrictions, the total height H1 (see FIG. 15) of the car room 201 needs to be lowered. However, if the height H2 from the floor to the lighting plate 103 is lowered, there is a problem that a feeling of pressure is felt when riding in the cab 201 and the riding comfort is not excellent.

  Under such circumstances, it is necessary to lower the height H3 of the elevator ceiling lighting apparatus 101. If this height H3 can be secured sufficiently, an illumination device that is excellent in design can be realized even by the installation method of the reflecting member 107 as described above. However, if the height H3 is lowered, the space between the light source 106 and the illumination plate 103 is reduced. Therefore, the shape of the light source 106 is clearly reflected on the illumination plate 103. In particular, a shadow appears prominently between the light source 106 and the light source 106, and the design cannot be improved.

  Increasing the number of light sources 106 to narrow the interval between the light sources 106, or increasing the voltage of the light sources 106 to increase the number of light beams emitted from the light sources 106 makes the shadows inconspicuous, but is undesirable because it increases power consumption. .

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a space-saving elevator ceiling lighting device that does not cause uneven light and shadows and saves power.

In order to achieve the above object, a first elevator ceiling lighting device according to the present invention includes:
A lamp holder that is attached to the ceiling of the elevator cab and holds the light source in a state of being spaced apart below the ceiling, an illuminating plate that is disposed substantially horizontally below the light source and transmits light from the light source, and the ceiling and the light source And a reflecting member that is disposed so as to be spaced from the ceiling and close to the light source, and irradiates light of the light source substantially uniformly toward the entire surface of the illumination plate.

The second elevator ceiling lighting device according to the present invention is
A lamp holder that is attached to the ceiling of the elevator cab and holds the light source in a state of being spaced apart below the ceiling, an illuminating plate that is disposed substantially horizontally below the light source and transmits light from the light source, and the ceiling and the light source And a reflecting member that is disposed so as to be close to the ceiling and the light source, and irradiates light of the light source substantially uniformly toward the entire surface of the lighting plate.

  The elevator ceiling lighting device according to the present invention can reduce the height by arranging the reflecting member so as to be close to the light source, so that space can be saved. Further, since the light reflection efficiency of the light source is improved, there is no shadow or uneven light between adjacent light sources, and it is not necessary to increase the voltage of the light source, so that power saving can be achieved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a cab equipped with an elevator ceiling lighting device according to the first embodiment of the present invention, FIG. 2 is an enlarged sectional view of a main part of FIG. 1, and FIG. 3 is an elevator ceiling lighting device of FIG. It is a disassembled perspective view.

  As shown in FIG. 1, the elevator ceiling lighting device 1 includes a lighting case 2 attached to a ceiling plate 202 of an elevator cab 201. The lower surface of the illumination case 2 has an opening, and an illumination plate 3 made of a light-transmitting material is attached substantially horizontally so as to cover the opening.

  As shown in FIGS. 2 and 3, a plurality of lamp holders 4 are fixed to the ceiling plate 202 with screws 5. The lamp holder 4 has a C-shaped lamp holder 4 a that holds the annular light source 6 in a state of being separated from the lower side of the ceiling plate 202.

  A reflecting member 7 is placed in contact with the upper portion of the light source 6. In other words, the reflecting member 7 is provided with a pair of through holes 7a for passing the upper part of the lamp holder 4 and a pair of through holes 7b for passing a screwdriver for turning the screw 5, from the through hole 7a to the lamp. With the upper portion of the holder 4 protruding upward, the lamp holder 4 is fastened and fixed to the ceiling plate 202 with screws 5 through a screwdriver through the through hole 7b.

  By installing the reflecting member 7 between the light source 6 and the ceiling plate 202, the light from the light source 6 is irradiated almost uniformly toward the entire surface of the illumination plate 3 to reduce unevenness of light, and the illumination device is excellent in design. Is realized.

  Since the reflecting member 7 is arranged so as to be close to the light source 6, the reflection efficiency is better than when the reflecting member 7 is arranged away from the light source 6, and the light flux of the light source 6 is apparently increased. Therefore, the shadow between the adjacent light sources 6 becomes inconspicuous, and it is not necessary to increase the voltage of the light source 6, so that power saving can be achieved.

  Further, by disposing the reflecting member 7 so as to be close to the light source 6, the height of the lighting device is reduced, and space can be saved.

  In addition, since the light source 6 is arranged away from the ceiling plate 202, even when a maintenance person gets on the ceiling upper surface and the ceiling plate 202 bends during inspection, the influence on the light source 6 is small and the light source 6 is damaged. Less dangerous.

  Furthermore, in this embodiment, since another component for positioning the reflecting member 7 is unnecessary, there is an advantage that the number of components can be reduced.
