Abstract: The present invention provides a lighting device in which a planar light-emitting panel is supported by, and can be easily attached to and detached from, a support member. The support member has a support side engagement part and covers a large part of a feeding wiring line. The lighting panel has a planar light-emitting panel and a mounting member. The planar light-emitting panel is attachable to the mounting member and has a panel side engagement part on its rear surface. The mounting member is fixable to the support member, and has first and second attaching side engagement parts. The first attaching side engagement part can engage the support side engagement part in a direction substantially orthogonal to the support member at a position overlapping with the planar light-emitting panel. The second attaching side engagement part can engage the panel side engagement part in the orthogonal direction.

Abstract: Provided is a light illumination system that, when a short-wavelength light curable resin is applied onto a body to be decorated such as an artificial nail or a nail of a fingertip, easily identifies a coating condition and a color of the short-wavelength light curable resin. This light emission system includes a short-wavelength light emission member and a pseudo natural light emission member, wherein the short-wavelength light emission member has a short-wavelength light emitting source in a casing, the casing has inside an opening that allows insertion of the nail therethrough, the short-wavelength light emitting source irradiates a short-wavelength light curable resin with short-wavelength light having a wavelength less than 410 nm to cure the resin, the pseudo natural light emission member has a planar light source, and the planar light source is located outside the casing and is capable of emitting diffusion light.

Abstract: The present invention provides a light-emitting panel attachment structure, a light-emitting panel aligned-arrangement structure, and a light-emitting panel that enable light-emitting panels to be arranged with no gap therebetween on an installation surface such as a ceiling. An attachment side fitting part is turnably attached to a coupling part. An attachment device is changeable between a parallel orientation in which the light-emitting panel is parallel to the installation surface and an intersecting orientation in which the light-emitting panel faces a direction intersecting the installation surface, along with the turn of the attachment side fitting part. When the light-emitting panel is attached to the attachment device, the attachment device is changed to or maintained in the intersecting orientation, and either the light-emitting panel or the attachment device is moved to slide parallel to an emission surface to fit a panel side fitting part with the attachment side fitting part.

Abstract: The present invention provides a light-emitting module capable of absorbing individual differences in organic EL panels that are inevitably generated in manufacture or individual differences between different types of organic EL panels. A connector includes a connection side circuit. The connection side circuit includes a circuit side power supply path that contributes to power supply to a light-emitting panel. The light-emitting panel includes an adjustment element and a light-emitting element. The adjustment element is capable of adjusting an electric resistance value and electrically connected to the light-emitting element through the circuit side power supply path.

Abstract: The present invention aims at providing a further downsizable organic EL module. Void parts are formed on first and second power supply members. The power supply members are different in shape, so that at least a part of the first power supply member is located in a vertically projected region of the second void part and at least a part of the second power supply member is located in a vertically projected region of the first void part when the power supply members overlap with an insulation layer sandwiched between. An electric wire penetrates the second power supply member to be connected to the first power supply member. The first power supply member is connected to one electrode layer directly or via a conducting member. The second power supply member, to which another electric wire is connected, is connected to another electrode layer directly or via a conducting member.
