Abstract: The present invention provides a lighting system that can produce a gradation of brightness and gives an unprecedented characteristic impression. The lighting system is provided on a mounting surface and includes a plurality of strip-shaped plates each extending in a strip shape and one or a plurality of planar light sources, in which the plurality of strip-shaped plates are each arranged side by side at an interval such that a main surface of the strip-shaped plate intersects the mounting surface, wherein arrangement space is provided in an area outwardly extending from the strip-shaped plates, the planar light source is disposed in the arrangement space and constitutes an lengthy emission surface, and a part of light emitted from the emission surface enters between the strip-shaped plates during lighting.

Abstract: An object of the present invention to provide a surface light-emission system that can change its posture and can be safely used. There is provided a surface light-emission system including: a surface light-emitting module including a surface light-emitting panel with an emission surface; and a supporting part rotatably supporting the surface light-emitting module in a circumferential direction directly or indirectly. Furthermore, In the surface light-emission system, the supporting part is capable of supplying electric power to the surface light-emitting panel and includes a movable range restriction unit restricting a movable range in a circumferential direction of the surface light-emitting module.

Abstract: 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.

Abstract: 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.

Abstract: According to an aspect, a lighting apparatus includes a lighting unit including a long-shaped housing that has upper and lower openings and has an outer surface formed as a convex surface when seen in a cross-section perpendicular to a longitudinal direction, and a semiconductor light emitting device disposed inside the housing so as to emit light toward the lower opening. Further, the lighting apparatus includes a holding unit including a holding member in which at least a portion of a surface is formed as a concave surface corresponding to the convex surface when seen in a cross-section perpendicular to the longitudinal direction of the lighting unit. When seen in the cross-section, the convex surface has, in a region that faces the concave surface, a portion that is brought into contact with the concave surface, and a portion that is not brought into contact with the concave surface.
