The lower support portion 132 is formed by being bent into an L shape, and has an elastic member that is supported from the inside of the lamp 200 by using an elastic force.

The lamp 200 includes a lamp main body 210 that forms an outer shell as a lighting device 1000, an upper light source unit 220 that is attached to the lamp main body 210 and illuminates upward, and a light source portion 220 that covers the light emitting direction of the upper light source unit 220. The upper translucent cover 230 attached to the 210, the lower light source unit 240 attached to the lamp main body 210 to illuminate the lower side, and the lower light source unit 240 covering the light emitting direction, and attached to the lamp main body 210. It has a lower translucent cover 250 and end covers 260 attached to both ends of the lamp main body 210.

The lamp body 210 is, for example, a frame molded by extruding aluminum, has a π-shaped cross section, and has an upper optical component mounting portion 211 to which an upper light source portion 220 is mounted on the upper surface and a lower surface on the lower surface. It has a lower optical component mounting portion 212 to which the light source portion 240 can be mounted, and an instrument main body mounting portion 213 located between the upper surface and the lower surface and to which the instrument main body 100 can be mounted. In this way, by using a metal member such as aluminum for the lamp body 210, the heat generated by the attached upper light source 220 or lower light source 240 is transferred and diffused, and is radiated into the outside air. It is possible to efficiently dissipate heat from the upper light source unit 220 and the lower light source unit 240.

The upper optical component mounting portion 211 holds the upper translucent cover 230 so as to be separated from the light emitting surface of the mounted upper light source portion 220 from the upper light source mounting portion 211a to which the upper light source portion 220 is mounted. It has a translucent cover mounting portion 211b.

Since the upper light source mounting portion 211a irradiates the ceiling surface side with the light emitted by the upper light source portion 220, the upper light source mounting portion 211a is inclined so as to irradiate the light toward the side opposite to the wall surface. An optical component such as a reflector or a lens may be used so that the ceiling surface can be irradiated. In this case, the surface on which the LED module (upper light source unit 220) is mounted so as to be perpendicular to the wall surface. May be horizontal to the floor. Further, when it is desired to irradiate the ceiling surface or the wall surface side directly above the lighting device 1000, the inclination of the upper light source mounting portion 211a and the optical components may be appropriately selected according to the application.

The upper translucent cover mounting portion 211b supports the upper translucent cover 230 by sandwiching both ends in the longitudinal direction, and defines a distance and an angle from the upper light source portion 220.

Similar to the upper optical component mounting portion 211, the lower optical component mounting portion 212 is separated from the lower light source mounting portion 212a to which the lower light source portion 240 is mounted and the light emitting surface of the mounted lower light source portion 240. It has a lower translucent cover mounting portion 212b that holds the lower translucent cover 250.

The lower light source mounting portion 212a is inclined so as to irradiate the wall surface side with the light emitted by the lower light source portion 240. An optical component such as a reflector or a lens may be used so that the wall surface can be irradiated. In this case, the surface on which the LED module (lower light source unit 240) is attached is arranged so as to be perpendicular to the wall surface. It may be horizontal to the floor. Further, when it is desired to irradiate the floor surface directly under the lighting device 1000 or the floor surface on the side opposite to the wall surface side, the inclination of the lower light source mounting portion 212a of the lower light source mounting portion 212a and the optical components are appropriately adjusted according to the application. You should select it.

The lower translucent cover mounting portion 212b sandwiches and supports both ends of the lower translucent cover 250 in the longitudinal direction, and defines the distance and angle from the lower light source portion 240.

The instrument body mounting portion 213 has an upper engaging portion 213a that rests on the upper side of the upper supporting portion 131 and a lower engaging portion 213b that engages with the elastic portion of the lower supporting portion 132 while being pressed. A screw hole 213aa is formed in the upper engaging portion 213a so as to correspond to the screw hole 131a.

The upper translucent cover 230 and the lower translucent cover 250 are formed of a rectangular flat plate, and are attached to the translucent cover mounting portions 211b and 212b by sliding them from the longitudinal direction, respectively. The upper translucent cover 230 and the lower translucent cover 250 may be a milky white diffusive cover, a transparent cover, a cover having an optical control function such as a lens, and unevenness instead of a flat plate. Or may be formed with a curved surface. When the upper translucent cover 230 includes an uneven shape, the unevenness on the outer surface side (the surface constituting the outer shell of the lighting device 1000) of the upper translucent cover 230 should be made as small as possible, or only the outer surface side should be uneven. It is preferable to eliminate.

The end cover portion 260 is attached to the end cover mounting plate 261 to be attached to the end of the lamp body 210 with screws or the like, and to the end cover mounting plate 261 with screws or the like to form an outer shell of the lighting device 1000.

Further, the surface shape of the sweep portion 263 may be flat or curved so that dust and dirt are less likely to be clogged during cleaning. The surface shape of the sweep portion 263 may be multi-faceted, but in this case, the surface shape may be a bent portion of 45 ° or less or a rounded bent portion so that dust and dust are less likely to be clogged. It is advisable to have a smooth surface shape.

In this way, the positional relationship between the surface of the upper translucent cover 230 and the surface of the sweeping portion 263 is substantially flush (a shape in which the surfaces are substantially connected to each other), or the surface of the sweeping portion 263 is the upper translucent cover 230. When wiping the upper translucent cover 230 with a rag or the like by lowering it one step from the surface of the upper translucent cover 230, by wiping the rag in the longitudinal direction, dust and dirt accumulated on the surface of the upper translucent cover 230 are swept out.
