Description

  The present invention relates to an elevator car display device for displaying information to passengers in an elevator car that moves passengers up and down in a hoistway such as a building.

  Some elevator cars have a display device attached to display information to passengers. Such a display device displays, for example, information for guiding the inside of a store or an advertisement information in an elevator of a store such as a department store or a mass retailer, or a painting for giving a sense of security to the passenger and softening the passenger. It is a device that displays artistic information such as.

  Conventionally, a guide plate on which guidance and information are written is attached as it is to a side plate constituting a part of a car to display the above information. However, such a guide plate is visually recognized by the passenger by the light from the lighting device in the car, and such a guide plate that does not emit light has a low visual effect on the passenger and does not attract the passenger's attention. The visual effect may not be sufficient.

  Moreover, as a conventional in-car display device, there is a display device in which an illumination device is incorporated. An example of a conventional display device in which such an illumination device is incorporated will be described with reference to a cross-sectional view shown in FIG. The display device 100 in the figure is attached to a side plate 2 that constitutes a part of an elevator car. The display device 100 is provided with a plurality of straight tube fluorescent lamps 101 provided in the vertical direction of the cage, and is provided on the side (front side) opposite to the side plate 2 when viewed from the fluorescent lamp, and is made of a light-transmitting material. An information display body 102 and a lamp box 103 provided so as to surround the fluorescent lamp 101 and having the information display body 102 attached to an opening formed on the side opposite to the side plate 2 when viewed from the fluorescent lamp. I have. The light emitted from the fluorescent lamp 101 is transmitted through the information display body 102 on which information is shown, so that the information displayed on the information display body 102 can be visually recognized by the passenger.

  However, since the in-car display device 100 shown in FIG. 3 uses a straight fluorescent lamp 101 similar to that used in ordinary homes, the size in the depth direction of the in-car display device 100 is as follows. The diameter of the fluorescent lamp 101 could not be made thinner. In addition, in the in-car display device 100 using the fluorescent lamp 101, the starting voltage necessary for lighting the fluorescent lamp 101 is also controlled in order to control the current supplied to the fluorescent lamp 101 to a value suitable for the fluorescent lamp 101. In order to supply an appropriate preheating voltage to the electrodes, it is indispensable to provide a ballast, and the entire display device including the ballast must be large. Therefore, when the in-car display device 100 is installed in the elevator car, there is a problem that the in-car display device 100 protrudes greatly in the car. In this regard, if the side display 2 of the car is provided with an opening and the in-car display device 100 is attached so as to protrude from the opening toward the hoistway, the inconvenience of projecting greatly into the car can be avoided. Another problem arises that leads to an increase in Furthermore, even though a plurality of fluorescent lamps 101 are provided, the light transmitted through the information display body 102 causes unevenness in illuminance within the surface of the information display body 102, so that the passengers feel uncomfortable. There was a risk of giving.

Further, in Patent Document 1, through a surface light-emitting plate disposed on a wall surface of a car room, light from a light source installed on an end surface of the surface light-emitting plate is surface-emitted, and reflection with a pattern provided on the back of the surface light-emitting plate. There is described an elevator car provided with an auxiliary illumination device that reflects a pattern and projects a pattern as a shadow on the front surface of the surface light emitting plate. However, since the auxiliary lighting device described in Patent Document 1 still uses a fluorescent lamp as a light source, the device becomes large overall, and even though it is a surface light emitting plate, it is actually on the end face. Since illumination is performed by the installed fluorescent lamp, unevenness in illuminance within the light emitting surface of the surface light emitting plate is unavoidable.
