Description

  The present invention relates to an elevator cab illumination device.

2. Description of the Related Art Conventionally, elevator cab lighting devices have fluorescent lamp type lighting fixtures arranged inside the ceiling. 12 to 16 show a conventional elevator cab illumination device. In the figure, 12 is a ceiling plate of a cab, 11 is a fluorescent lamp type lighting fixture arranged in the ceiling of the cab on the back of the ceiling plate 12, and 13 is a lighting plate made of milky white resin that transmits light from the lighting fixture 11. , 14 is a reflector.
As is apparent from FIGS. 13 to 15, the conventional elevator cab lighting device requires a space that is occupied by the fluorescent lamp type lighting fixture 11, and particularly has a vertical dimension of about 150 mm. It was extremely large. Further, as shown in FIG. 15, the light emission direction from the fluorescent lamp luminaire 11 emits light in a useless direction such as the opposite direction of the illumination plate 13. Furthermore, when exchanging the fluorescent lamp-type lighting fixture 11, as shown in FIG.

  In order to solve this problem, an in-car lighting lamp in which a plurality of white light emitting elements are arranged vertically and horizontally with a predetermined interval is attached to the ceiling plate in the car, and light of a color close to that of a conventional incandescent lamp or fluorescent lamp is attached. There is an elevator car lighting device that illuminates the car by emitting

However, the conventional elevator cab lighting device requires a space of a size occupied by the lighting fixture, and particularly the vertical dimension is extremely large, and therefore it is difficult to reduce the vertical dimension of the hoistway. In addition, when the design is changed, it is necessary to change the position of the lamp of the lighting fixture, and it is impossible to easily change the design of the lighting plate and the like. In addition, the power consumption cannot be reduced, which has been an impediment to effective use of the building space.
Moreover, in the elevator car lighting device described in Patent Document 1, it is possible to reduce power consumption and the space of the car lamps to some extent. Enhancing design variations was still insufficient.

  The present invention has been made to solve the above-described problems, and uses an LED (light emitting diode) for a ceiling lighting fixture in a cab, greatly reducing the vertical space occupied by the lighting fixture. Provided is an elevator cab lighting device that can contribute to the reduction of the vertical dimension of a hoistway.

  In the elevator cab lighting device according to the present invention, the ceiling plate of the elevator cab, a number of LED lighting fixtures arranged obliquely or vertically on the back surface of the ceiling plate portion, and the light emitting direction of the LED lighting fixtures And an illuminating plate made of a translucent material provided on the ceiling plate so as to face each other.

  According to this invention, since the LED can be used for the ceiling lighting fixture in the cab and the vertical space occupied by the lighting fixture can be greatly reduced, it contributes to space saving of the elevator equipment, particularly to reduction of the vertical dimension of the hoistway. Can reduce the construction cost.

In the figure, 1 is an LED lighting fixture made up of a large number of LEDs (light emitting diodes), 2 is a ceiling plate of an elevator cab that is formed by gradually increasing the shape of a plurality of rectangular frames from the inside to the outside, 3 The illumination plate is made of a translucent material such as milky white resin, which has an opening formed in a vertical surface of a quadrangular frame of the ceiling plate 2 and is detachably attached so as to close the opening.
As shown in FIG. 3, the LED lighting device 1 is attached to the back surface in the ceiling plate 2 in an oblique direction or in a vertical direction, and is disposed at a position facing the detachable lighting plate 3 at a predetermined interval. Has been.
When the LED lighting fixture 1 of the present invention is used, the vertical dimension is about 25 mm, and the equipment configuration of the cab lighting device is possible in about 1/6 of the space of the conventional fluorescent lamp type lighting fixture 11. . By this dimension reduction, the vertical dimension of the hoistway can be reduced by about 125 mm as compared with the prior art. Moreover, as shown in FIG. 4, since the LED lighting apparatus 1 emits light efficiently in a certain direction, energy efficiency is also good.

Embodiment 2. FIG.
5 is a bottom view showing an elevator cab illumination device according to Embodiment 2 of the present invention, FIG. 6 is a sectional view taken along line BB in FIG. 5, and FIG. 7 is an elevator according to Embodiment 2 of the present invention. 8 is a bottom view showing a part of the car room lighting device, and FIG. 8 is a cross-sectional view of the main part showing the light emitting direction of the LED lighting fixture of the elevator car room lighting device in Embodiment 2 of the present invention.

In the figure, 1 is an LED lighting device made up of a large number of LEDs (light emitting diodes), 2 is a ceiling plate of a cab that is formed by gradually increasing the shape of a plurality of circular frames from the inside to the outside, 3 It is an illumination plate made of a translucent material such as milky white resin, in which an opening is formed in a vertical surface of a circular frame of the ceiling plate 2 and is detachably attached so as to close the opening.
As shown in FIGS. 7 and 8, the LED illumination device 1 is attached along the circumference of the back surface in the ceiling plate 2 in an oblique direction or a vertical direction, and the removable illumination plate 3. Are disposed at positions facing each other at a predetermined interval.
When the LED lighting fixture 1 of the present invention is used, the vertical dimension is about 25 mm, and the equipment configuration of the cab lighting device is possible in about 1/6 of the space of the conventional fluorescent lamp type lighting fixture 11. .

Embodiment 3 FIG.
FIG. 9 is a bottom view showing an elevator cab lighting device according to Embodiment 3 of the present invention, and FIG. 10 is a cross-sectional view taken along the line CC of FIG.

  FIG. 9 shows an example in which unevenness of light does not occur when the LED lighting apparatus 1 is changed. When indirect light as shown in FIG. 9 is used, light unevenness occurs at the seam in the case of a fluorescent lamp type. However, when an LED lighting apparatus is used, the design is improved because there is little light unevenness due to a continuous light source. . Although difficult to express in the drawings, the color of light can be freely changed, so that a special effect of producing a sense of depth in a narrow space can be achieved.
