Description

  Embodiments described herein relate generally to an elevator car interior lighting device.

  The elevator car is provided with an in-car ceiling lighting device that illuminates the inside of the car. As described in Patent Document 1 below, such an elevator car interior ceiling lighting device includes a straight tube fluorescent lamp attached to a ceiling portion in the car, and a lower part of the straight tube fluorescent lamp. And an illuminating plate made of translucent resin disposed on the side.

  The lighting plate has various shapes and structures, for example, a flat plate arranged directly under the fluorescent lamp, or a ceiling side arranged between adjacent fluorescent lamps located in parallel. There is a convexly curved shape.

  The irradiation direction of light from the straight tube fluorescent lamp is uniform toward the entire circumference in the radial direction of the straight tube fluorescent lamp. For this reason, even when a flat illuminating plate is arranged directly below the straight tube fluorescent lamp, the illumination is curved in a convex shape toward the ceiling between the adjacent straight tube fluorescent lamps Even when the plates are arranged, there is no need to consider the rotation angle around the center line of the straight tube fluorescent lamp when the straight tube fluorescent lamp is mounted on the ceiling.

JP 2010-58880 A

  In recent years, LED lamps that consume less power and have a long lifetime have become widespread. Also in an elevator car ceiling lighting device, an LED lamp (straight tube fluorescent lamp type LED lamp) having the same external shape as a straight tube fluorescent lamp may be used.

  The straight tube fluorescent lamp type LED lamp has a substrate in which a plurality of LEDs are arranged on one surface, and this substrate is accommodated in a cylindrical tube having substantially the same shape as the appearance of the straight tube fluorescent lamp. . Therefore, the irradiation direction of light from the straight tube fluorescent lamp type LED lamp is only the direction of the surface on which the LEDs are arranged on the substrate. For this reason, when the straight tube fluorescent lamp type LED lamp is mounted on the ceiling of the car, the straight tube fluorescent lamp type LED is arranged so that the light emitted from the straight tube fluorescent lamp type LED lamp faces the direction of the illumination plate. It is necessary to consider the rotation angle around the center line of the lamp.

  By the way, the form of the elevator car is not constant, the width of the car is different, and the shape and installation position of the lighting plate attached to the ceiling of the car are different. For this reason, when mounting a straight tube fluorescent lamp type LED lamp on the ceiling in a different type of car, using the same mounting parts, the light emitted from the straight tube fluorescent lamp type LED lamp is directed toward the illumination plate. The case where it does not face is generated. Therefore, in order to direct the light irradiation direction from the straight tube fluorescent lamp type LED lamp mounted on the ceiling portion in the car to the direction of the lighting plate even when the car type is different, the straight tube fluorescent lamp type LED is used. It is necessary to prepare multiple types of mounting parts for mounting the lamp on the ceiling in the car, and to install the straight tube fluorescent lamp type LED lamp using the most suitable mounting parts according to the car type .
