Abstract: A lighting unit body comprises: a light source; and shaped-members, in which a housing portion in which the light source is disposed, reflective surfaces for reflecting light from the light source, and an emission outlet for emitting the light from the reflective surfaces are respectively formed in the longitudinal direction. When a position at which the emission outlet is disposed is defined as forward and a direction orthogonal to the longitudinal direction is defined as a front-to-rear direction, and a direction orthogonal both to the longitudinal direction and the front-to-rear direction is defined as a left-to-right direction, then the emission outlet is formed in a front portion of the reflective surfaces, and the housing portion is formed in a rear portion of the reflective surfaces directed obliquely rearward at a predefined inclined angle on one of left or right side.

Abstract: A wiring duct plug that does not have a movable part for selecting any of a plurality of conductive lines, and has a high operational reliability is provided. A wiring duct plug can be directly connected to a respectively corresponding conductive line, and comprises a plurality of movable electrode terminals, rotating together with a rotator. At the connection position, at least two but not all of the plurality of movable electrode terminals are joined into one at the base end portion and electrically coupled to one of non-movable electrode terminals, and the remaining movable electrode terminal is electrically coupled to the other non-movable electrode terminal.

Abstract: A wiring duct plug that does not have a movable part for switching and thus has a higher operational reliability is provided. A plug (wiring duct plug) 2 for use mounted in a wiring duct, in which a plurality of conductive lines are installed, comprises a rotatable rotator 17, a pair of non-movable electrode terminals 2a-c? and 2d?, and a plurality of movable electrode terminals 2a to 2d. The plurality of movable electrode terminals 2a to 2d rotate with the rotator 17 and are placed either at a connection position for electrically coupling the plurality of conductive lines and the pair of non-movable electrode terminals 2a-c? and 2d?, or at a release position for releasing electrical connection.

Abstract: Provided is a power supply box device that improves design properties by keeping an operation lever from being visible from outside and that prevents misoperations caused by the operation lever being touched by mistake. A power supply box device 1 that comprises a plug 30: that has an operation lever 31m that protrudes in a radiation direction from a plug main body and extends downward; and that is supported by a lid member so as to be capable of forward and reverse rotation. A box main body has: a housing 12 that houses a power supply; and a lever cover 13 that is supported by the housing 12 so as to be capable of ascending/descending between a lock position that is on an upper side and a lock release position P2 that is on a lower side.

Abstract: An illumination apparatus includes: a reflector having a first reflection surface with a shape of a surface of revolution, and a downward light emission outlet through which direct light from a light source and reflection light from the first reflection surface being emitted; and a cone having a substantially truncated conical second reflection surface, an upper opening opposing the light emission outlet, and a lower opening having a larger diameter than the upper opening. The cone is positioned outside the optical paths of the controlled reflection light from the first reflection surface.

Abstract: A sharpener comprises a cylindrical inner louver portion and a cylindrical outer louver portion each disposed concentrically about an axis that extends forward from a center of a light-emitting surface. Respective back ends of the inner louver portion and the outer louver portion are disposed nearer to the light-emitting surface, and respective front ends and are disposed farther from the light-emitting surface, and the front end of the inner louver portion is disposed nearer to the light-emitting surface than the front end of the outer louver portion is.

Abstract: A lighting device includes a body defining a central axis, a reflector defining an optical axis at an angle with respect to the central axis, and a planar light source defining a surface inclined with respect to a first plane orthogonal to the optical axis. The optical axis being inclined towards one side of the central axis such that the light emission direction of the planar light source is inclined towards an opposite side with respect to the central axis.

Abstract: A reflector disposed in an inclined orientation such that the lower portion of an axis is located nearer to a wall surface. A light-emitting surface of a planar light source is inclined with respect to a first virtual plane that is perpendicular to the axis, such that a portion farther from the wall surface is located relatively upper. In other words, the light-emitting surface is oriented toward a region of the reflector located farther from the wall surface than the axis.
