Lighting device and lighting panel with mounting member, connecting member, and engagement parts

A lighting device, comprising:

• a first lighting panel;
• a support member extending in a predetermined direction;
• and
• a feeding wiring line configured to feed power to the first lighting panel,
• the support member having a support side engagement part,
• the feeding wiring line being mostly covered with the support member,
• the first lighting panel including:
• a planar light-emitting panel having an emission surface;
• and
• a mounting member that attaches the planar light-emitting panel to the support member,
• wherein the planar light-emitting panel is attachable to and detachable from the mounting member, the planar light-emitting panel having a panel side engagement part on a rear surface thereof,
• wherein the mounting member is fixable to the support member at a plurality of positions in an extending direction of the support member, the mounting member having a first attaching side engagement part and a second attaching side engagement part,
• wherein the first attaching side engagement part is engageable with the support side engagement part at a position overlapping with the planar light-emitting panel when the emission surface is viewed from a direction in front of the emission surface, the first attaching side engagement part being engageable with the support side engagement part in a direction substantially orthogonal to the extending direction of the support member,
• wherein the second attaching side engagement part is engageable with or disengageable from the panel side engagement part in the direction substantially orthogonal to the extending direction of the support member,
• wherein the support member has a plurality of the support side engagement parts provided at an interval in the predetermined direction,
• wherein the mounting member has a first attaching side engagement part engageable with each of the plurality of the support side engagement parts, and
• wherein a position of the first lighting panel with respect to the support member is adjustable by disengaging the first attaching side engagement part from one support side engagement part of the plurality of support side engagement parts and engaging with a different support side engagement part of the plurality of support side engagement parts;
• wherein the lighting device further comprises a second lighting panel provided in parallel with and adjacent to the first lighting panel in the extending direction of the support member,
• wherein the second lighting panel includes a second planar light-emitting panel having an emission surface, and a second mounting member having a first connecting unit and a second connecting unit,
• wherein the second connecting unit connected to the second planar light-emitting panel is configured to change a posture with respect to the first connecting unit, and
• wherein the second lighting panel is capable of changing its posture to a first posture and to a second posture by changing a posture of the second connecting unit with respect to the first connecting unit,
• the first posture being a posture in which the emission surface of the second planar light-emitting panel faces an identical direction to the emission surface of the planar light-emitting panel of the first lighting panel,
• the second posture being a posture in which the emission surface of the second planar light-emitting panel faces a direction substantially orthogonal to the extending direction.
