The present invention provides an illumination apparatus that can suppress heat generation during use. The illumination apparatus includes a planar light emitting panel and a heat-radiating mounting member. The mounting member mounts the planar light emitting panel and has a body plate-section. The body plate-section has a through hole for feeding power that penetrates the body plate-section in a thickness direction, and a smooth region substantially free of protrusions. The panel has a panel body and a connecting wiring section. The connecting wiring section electrically connects the panel body to an external power source, and extends through the through hole. The panel has a front surface including a light emitting region that emits light, and a back surface on which another smooth region is provided. The smooth regions are in surface contact with each other over not less than 50% of an area of the light emitting region.

Illumination apparatus

The present invention provides an illumination device in which an organic EL panel is detachable from a mounting member; the panel has a panel body and a fixing member. The panel body has an emission surface on its front and a circuit board on its rear. The fixing member has a main body and a raised part that is disposed on a rear of the panel and raised with respect to the main body to circumvent the circuit board and to protect the circuit board. The raised part includes a raised-side engagement part protruding in a direction crossing a raised direction. The mounting member has an attachment side main body and an attachment side engagement part. The attachment side engagement part extends from the attachment side main body to form a step. The engagement parts engage together when the panel is attached to the mounting member.
