Description

  The present invention relates to an elevator display and a lighting device excellent in design.

In conventional elevator display and illumination devices, light unevenness and light source reflection may occur due to the fact that the light source is behind the display plate and the illumination plate, or the distance between the display plate and the illumination plate is small. There was a problem that design nature was bad.
In addition, as another conventional technique, it can be formed sufficiently wide on a floor surface of an elevator display device or a car floor that displays a required display action by simple processing, and the peripheral portion of the translucent plate is illuminated. There is a leg lighting device for an elevator car that realizes a leg lighting effect (see, for example, Patent Document 1 and Patent Document 2).
