Description

  The present invention relates to a planar light-emitting luminaire that includes a hooking portion on one surface of a planar light emitting module and attaches the hooking portion to a mounting surface such as a ceiling.

Some planar light-emitting luminaires include a planar light-emitting module and a hooking portion provided on the back surface of the planar light-emitting module.
Since this planar light-emitting luminaire usually has a reflective surface, the planar light-emitting module is opaque, and therefore the hanging receiving portion cannot be directly visually recognized from the surface side of the planar light-emitting module.
For this reason, when attaching the hanging receiving part of the planar light-emitting lighting fixture to the hanging part, it takes time to perform the attaching operation.

In order to solve this problem, a hooking part is provided on the back side of the planar light emitting module, and the part facing the hooking part of the planar light emitting module is transparent, and is hooked from the surface side of the planar light emitting module. There has been proposed a planar light-emitting luminaire that can visually recognize a portion (see, for example, Patent Document 1).
