Move to. At this time, the peripheral edge portion of the panel 3 is fitted into the fitting portions 5 </ b> A of the two main body side support members 5 facing each other.

  By moving the panel 3 in the horizontal direction, the panel-side support member 6 approaches the column 14 exposed downward from the bottom surface of the frame body 2 as shown in FIG. At this time, the peripheral edge portion of the panel 3 is fitted in both the fitting portions 5A of at least the two main body side support members 5 facing each other, and the panel 3 can be held by one hand of the operator. Therefore, the stopper 22 is pushed upward against the elastic force of the coil spring 23 by the other hand of the operator, and the pin 20 extending in the horizontal direction from the support bar 6D of the panel side support member 6 is inserted into the recess 21 of the support column 14. Inset. By inserting the pins 20 into the recesses 21, the panel-side support member 6 is supported by the columns 14. At this time, the peripheral edge portion of the panel 3 is also inserted into the insertion portion 5A of the main body side support member 5 facing the panel side support member 6, and the panel 3 is held in the vertical direction at four locations on the peripheral edge portion.

  Further, when the operator's hand is released from the stopper 22, the stopper 22 moves downward and contacts the outer surface of the support bar 6 </ b> D, and this state is maintained by the elastic force of the coil spring 23. Therefore, the panel 3 is reliably restricted from moving in the horizontal direction at the four peripheral edge portions.

  When removing the panel 3 from the main body 1, as shown in FIG. 4 (C), the support rod 6D is pushed with the stopper 22 pushed up against the elastic force of the coil spring 23 with one hand of the operator. The outer surface of the panel 3 is opened and a part of the peripheral edge of the panel 3 is gripped by the other hand of the operator, and as shown in FIG. 4 (D), the panel 3 is horizontal from a position facing the lower side of the reflecting surface 1B. Pull in the direction.

  Thus, the panel 3 can be attached to and detached from the main body 1 only by moving the panel 3 in the horizontal direction with respect to the main body 1, and there is no need to move the panel 3 in the vertical direction. Further, a part of the main body side support member 5 that supports the panel 3 is always located below the panel 3 during the operation of attaching and detaching the panel 3, and the operator visually recognizes the arrangement position of the main body side support member 5. Detachment work can be performed. For these reasons, the panel 3 can be attached to and detached from the main body 1 very easily and safely.

  In the above example, three main body side support members 5 are arranged. However, the present invention is not limited to this, and two main body side support members 5 and one panel side support member 6 are connected to the panel 3. You may arrange | position in the three places of equal intervals in the circumferential direction of a peripheral part. However, when the main body side support member 5 and the panel side support member 6 are arranged at five or more positions at equal intervals in the circumferential direction of the peripheral edge of the panel 3, the panel 3 can be inserted and removed in the horizontal direction. become unable.

  Further, in the above example, the illumination device 10 is formed in a circular shape in plan view, but the present invention can be similarly applied to the illumination device 10 that has a rectangular shape in plan view. In this case, the single main body side support member and the panel side support member may be arranged so as to face only two side surfaces of the rectangular panel that face each other.

  Furthermore, in the above example, the ceiling light mounted on the ceiling surface has been described as an example. However, the present invention can be similarly applied to a lighting fixture in which the mounted surface is a vertical wall surface. In addition, in lighting fixtures, regardless of whether the panel surface is arranged horizontally or vertically, the panel is moved only in the direction parallel to the panel surface so that the panel can be attached to and detached from the main body. It can be configured.
