Document Type and Number:
WIPO Patent Application WO/2017/187819
Kind Code:
A1
Abstract:
The present invention provides an illumination device that can be made thinner than in the past, the device being provided with an organic EL panel which is replaceable and on which a circuit board is mounted. The organic EL panel, which can be attached to and detached from an attachment member, has a panel body and a securing member. The panel body has a light-emitting surface on the front-surface side and a circuit board on the rear-surface side. The securing member has a main body part and a raised part, the raised part being disposed on the rear-surface side of the organic EL panel, rising up in relation to the main body part so as to avoid the circuit board, and protecting all or part of the circuit board. The raised part is provided with a raised-side engagement part projecting in a direction that intersects the direction in which the raised part is raised. The attachment member has an attachment-side body part and an attachment-side engagement part, the attachment-side engagement part extending from the attachment-side body part and forming a step from the attachment-side body part. The raised-side engagement part and the attachment-side engagement part are engaged when the organic EL panel is attached to the attachment member.
