Description

  The present invention relates to a lighting fixture including a light-emitting panel, and more particularly to a light-emitting panel type lighting fixture in which a plurality of light-emitting panels are connected by hinges at end portions.

  Lighting fixtures that use light-emitting panels as light sources are known, but due to demands for miniaturization of lighting fixtures and higher output efficiency, the parts exposed when installed indoors, such as the frame edges of lighting fixtures, are made smaller. There is a tendency to increase the area occupied by the light-emitting panel. In that case, when installing or replacing the light-emitting panel, it is necessary to place the edge of the light-emitting panel on the support part of the lighting fixture near the ceiling, that is, the light-emitting panel having a relatively large area at a high place. Therefore, there is a possibility that the workability may be deteriorated.

  On the other hand, as a lighting fixture that is reduced in size and weight and is easy to store and carry, there has been proposed one in which a plurality of surface light emitting portions made of EL elements are connected by a hinge (for example, Patent Document 1). ). The lighting fixture of Patent Document 1 includes a plurality of light source support plates made of a light-shielding material, a surface light emitting unit, and a hinge. And the edge part of a light source support plate is connected with a hinge, and folding and expansion | deployment are performed freely, and thickness reduction and weight reduction are achieved.

When the light emitting panel is connected using a pivotable hinge, the light emitting panel can be attached or replaced with the hinge folded. In other words, with the folded part held in the hand, the edge of the light-emitting panel that is not attached with the hinge is placed on the support rail provided on the lighting fixture, and the bent portion by the hinge is pushed up to the fixture side to support it. The edge portion can be slid on the rail and can be mounted in a predetermined support portion. Similarly, when removing, the edge of the light-emitting panel is slid on the support rail to remove the light-emitting panel from the support, the hinge is rotated and pulled down to the indoor side, and the light-emitting panel can be removed from the support rail with this.
