Title:
ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003911
Kind Code:
A1
Abstract:
The present invention provides an illumination device in which it is possible to suppress generation of heat during lighting. The present invention has a surface light-emitting panel and a heat-emitting attachment member. The heat-emitting attachment member attaches the surface light-emitting panel to an attachment-subject part, and has a body plate part. The body plate part has a power-feed through-hole passing through in the thickness direction, and an attachment-side smooth region that is substantially free of protrusions. The surface light-emitting panel has a panel body and a connection wiring part. The connection wiring part electrically connects the panel body and an external power source, and extends from the panel-body side of the body plate part through the power-feed through-hole to the opposite side of the panel body. The surface light-emitting panel is configured so that a light-emitting surface that includes a light-emitting region for emitting light during lighting constitutes an obverse surface, the surface light-emitting panel having, on a reverse surface, a panel-side smooth region that is substantially free of protrusions. The attachment-side smooth region and the panel-side smooth region are in surface contact with each other in at least 50% of the area of the light-emitting region when the light-emitting surface is seen in plan view.
