FIG. 2 is a flow chart showing a procedure for replacing the existing lighting device with the lighting device of FIG. 1 (a method for replacing the lighting device).
Hereinafter, the replacement work of the illumination device will be described with reference to FIG.
FIG. 2 (a) shows an existing lighting device installed in an elevator car. In the figure, 101 is an illumination plate, 102 is a fluorescent lamp, 103 is a canopy, 104 is a frame, and 105 is attached to the frame 104. This is a spring fixing tool (illuminating plate holder).

In the state where the existing lighting device is installed, the lighting plate 101 is held by the spring fixture 105 as shown in FIG.
At this time, in the drawing, the left spring fixture 105 presses the illumination plate 101 in the right direction by the spring, and the right spring fixture 105 presses the illumination plate 101 in the left direction by the spring.
When the replacement worker applies a force in the left direction that is greater than the pressing force of the spring of the spring fixture 105, for example, as shown in FIG. 2B, the left spring fixture 105 is moved together with the lighting plate 101. Move left.
Thereby, as shown in FIG. 2C, the right end of the illuminating plate 101 does not overlap the frame 4, so that the illuminating plate 101 can be removed.

When the replacement worker removes the illumination plate 101 from the existing illumination device, the exchange worker removes the fluorescent lamp 102 as shown in FIG.
In the example of FIG. 2, the fluorescent lamp 102 is removed, but a new illumination device can be attached without removing the fluorescent lamp 102.
In the lighting device of the present invention, it is not necessary to remove the canopy 103 and the frame 104 of the existing lighting device, and thus the removal work of the existing lighting device is completed.

When the removal work of the existing lighting device is completed, the replacement worker installs the power supply device 5 for supplying power to the light source 4 of the new lighting device (the lighting device in FIG. 1) as shown in FIG. The work of attaching to the canopy 103 of the lighting device is performed (the work of attaching the power supply device 5 will be described later).
At this time, as shown in FIG. 2 (e), the upper part of the car is connected to an existing main power supply 106 (for example, a building switchboard, an elevator drive mechanism, etc.). The power supply 5 is required to be connected to the existing main power supply 106.
This power supply connection step is a necessary step for both the conventional lighting device and the lighting device of the present invention.
The power supply device 5 performs processing such as converting the voltage of power supplied from the main power supply 106 into a voltage suitable for the light source 4.

When the replacement worker attaches the power supply device 5 to the canopy 103 of the existing lighting device, as shown in FIG. 2 (g), the lighting device of FIG. 1 is inserted into the space in the frame 104 in the existing lighting device, The power supply device 5 and the light source 4 are connected by a power supply line.
When the replacement worker connects the power supply device 5 and the light source 4 with a power supply line, as shown in FIG. On the other hand, the lighting plate frame body 2 is set so as to fit into the left and right spring fixtures 105.
FIG. 2 (i) shows a state where the mounting of the lighting device of FIG. 1 is completed.
