[0013] A lighting fixture 1 according to one embodiment of the present invention will be described with reference to Figs. 1 to 5. The lighting fixture 1 according to this embodiment is attached to a wall surface that is provided in a vertical (or approximately vertical) direction, and has irradiation surfaces on both the upper and lower sides when attached to the wall surface. The mounting surface side of the lighting fixture 1 is the side of the lighting fixture 1 that faces the wall surface, and is the back side. A side view refers to a state in which the lighting fixture 1, etc. is viewed from a direction perpendicular to the up-down direction when the lighting fixture 1 is attached to a wall surface. A cross-sectional view refers to a state in which the cross-sectional shape of the lighting fixture 1, etc. is viewed.

[0014] As shown in Figures 1 to 3, the external shape of the lighting fixture 1 is configured to be a substantially cubic shape. The external shape of the lighting fixture 1 is not limited to that of the present embodiment, and other than the substantially cubic shape, it can be, for example, a substantially circular shape, an elliptical shape, a rectangular shape, a polygonal shape, a sector shape, or a combination of these shapes in a plan view. As shown in Figures 4 and 5, the lighting fixture 1 mainly includes a lamp 10 and a fixture body 20.

[0015] The lamp 10 is a lamp having a base structure of GX53 type, which is an example of a flat lamp, and is disposed in a housing 30 of an instrument body 20, which will be described later. The lamp 10 is configured to be approximately cylindrical. The lamp 10 is configured so that one axial end side thereof is in the direction of light irradiation, and the other axial end thereof is configured to have an approximately cylindrical convex portion which is inserted into a central opening of a socket 13, which will be described later. Note that the lamp 10 is not limited to being GX53. The lamp 10 and the socket 13 are not limited to being compatible with a GX53 type base, and may be compatible with a GH76p type base or a GH69h type base.

[0016] The fixture body 20 has a housing 30, and the lamp 10 is disposed inside the housing 30. The housing 30 is fixed to a wall surface via a fixture mounting plate 24 that is attached to the wall surface. The housing 30 has a side plate portion 31, an upper panel 32, and a lower panel 33.

[0017] The side plate portion 31 is formed in a substantially rectangular tubular shape formed by connecting plate-like members so as to surround the front, top, bottom, left and right sides, and has an opening 31a on the upper surface and openings 31b and 31c on the lower surface. The upper panel 32 is a flat plate-like member and is formed in a substantially rectangular shape in a plan view. The upper panel 32 is translucent and is disposed so as to cover the opening 31a on the upper surface of the side plate portion 31. The upper panel 32 is configured to be detachable from the side plate portion 31. The lower panel 33 is a flat plate-like member and is formed in a substantially rectangular shape in a plan view. The lower panel 33 is translucent and is disposed so as to cover the opening 31b on the lower surface of the side plate portion 31. The lower panel 33 is configured to be detachable from the side plate portion 31. Light emitted from the lamp 10 is irradiated to the outside of the housing 30 through the upper panel 32 and the lower panel 33. Incidentally, by using a plate material or the like that does not have translucency in place of the top panel 32 in the housing 30, the lighting device 1 can be configured to irradiate light only downward. Also, by cutting out a part of the side wall of the housing 30, the lighting device 1 can be configured to irradiate light from a part of the side plate portion 31 as well.

[0018] The device main body 20 has a base 11, a socket mounting base 12, a terminal base 21, a sensor unit mounting base 22, a sensor unit 23, a device mounting plate 24, and a packing 25. The base 11, the socket mounting base 12, the terminal base 21, the sensor unit mounting base 22, and the sensor unit 23 are disposed at predetermined positions within the housing 30.

[0019] Base 11 is a flat plate-like member and is configured to have a substantially rectangular shape in a side view. Base 11 is disposed within side plate 31, toward the rear side of side plate 31. Base 11 is attached to side plate 31 with fixing members such as screws. When lighting fixture 1 is attached to a wall surface, base 11 is disposed so as to be substantially parallel to the wall surface. The socket mounting base 12 is a member for mounting the socket 13 to the base 11, and is fixed to the base 11 by a fixing member such as a screw. The socket mounting base 12 is configured to protrude from the base 11 to the front side. The socket mounting base 12 is formed, for example, by bending a flat metal member. The socket mounting base 12 has a mounting portion 12a and a pair of left and right foot portions 12b·12b. The mounting portion 12a is a portion to which the socket 13 is attached, and is configured to have a flat, approximately rectangular shape. The foot portions 12b are configured to protrude from the left and right edges of the mounting portion 12a to the rear side. The rear side end of the foot portion 12b is bent into an approximately L-shape and fixed to the front side of the base 11 by a fixing member such as a screw. In this embodiment, in the socket mounting base fixed to the base 11, the upper end of the mounting portion 12a protrudes more toward the front side than the lower end, and is disposed in an inclined position with respect to the base 11. The socket 13 is configured so that the lamp 10 can be attached thereto. The socket 13 is fixed to the mounting portion 12a of the socket mounting base 12 by a fixing member such as a screw. The socket 13 is configured so as to protrude from the mounting portion 12a of the socket mounting base 12 to the front side. The socket 13 is configured in a substantially annular shape and has an opening in the center. The lamp 10 is attached to the socket 13 by inserting a protruding portion of the lamp 10 into the opening of the socket 13. One axial end of the socket 13 is configured as a mounting surface for the lamp 10, and the other axial end of the socket 13 faces the mounting portion 12a while being fixed to the mounting portion 12a.

[0020] The terminal block 21 is connected to an electric wire of an external power source, and is fixed to the base 11 by a fixing member such as a screw. The terminal block 21 is configured to protrude from the base 11 to the rear side. The sensor unit mounting base 22 is a member for attaching the sensor unit 23 to the base 11, and is fixed to the base 11 with fixing members such as screws. The sensor unit mounting base 22 is configured to protrude from the base 11 to the rear side. The sensor unit mounting base 22 is configured, for example, by bending a flat metal member. The sensor unit 23 is fixed to the sensor unit mounting base 22 by a fixing member such as a screw. The sensor unit 23 is, for example, a human presence sensor, and has a detection unit and an operation unit at its lower end. The sensor unit 23 is disposed on the rear side within the housing 30. The sensor unit 23 is configured so that its lower end, detection unit, and operation unit are exposed from an opening 31c on the lower surface of the side plate 31. The lower panel 33 is disposed in a portion of the lower opening of the side plate 31 where the lower end of the sensor unit 23 is not disposed. Note that the sensor unit 23 is not limited to being a human presence sensor, and may be configured with other sensors such as an illuminance sensor, or may be configured with a device that performs other functions (for example, a wireless communication device, a camera, a speaker, a projector, etc.). The fixture mounting plate 24 is a member for mounting the housing 30 (side plate portion 31) to a wall surface, and is fixed to the rear side portion of the side plate portion 31 by fixing members such as screws. The fixture mounting plate 24 is disposed on the rear side of the base 11. The fixture mounting plate 24 is formed by bending a flat plate-shaped member. The packing 25 is formed in a flat plate shape, and is disposed between the fixture mounting plate 24 and the side plate portion 31. The fixture mounting plate 24 and the packing 25 are attached to the wall surface by fixing members such as screws. The lighting fixture 1 can be attached to the wall surface by attaching the housing 30 (side plate portion 31) to the fixture mounting plate 24 attached to the wall surface.

[0021] Socket 13 (the axial direction of socket 13) is arranged in an inclined position relative to the wall surface. In lighting fixture 11 of the present embodiment, the surface of mounting portion 12a of socket mounting base 12 is arranged in an inclined position relative to the flat surface of base 11, so that socket 13 is arranged in an inclined position relative to the wall surface. And, by arranging socket 13 in an inclined position relative to the wall surface, lamp 10 is configured so that its irradiation direction is inclined relative to the wall surface. Lamp 10 is configured so that its irradiation direction is inclined downward (diagonally downward) from the front side. The inclination angle θ1 of the mounting portion 12a of the socket mounting base 12 relative to the plane of the base 11 correlates with the inclination angle of the irradiation direction of the lamp 10 (in this embodiment, the inclination angle downward from the vertical direction of the wall surface). Here, the inclination angle θ1 between the base 11 and the mounting portion 12a is treated as being equivalent to the inclination angle θ1 of the irradiation light of the lamp 10. The inclination angle θ1 of the lamp 10 is configured to be in the range of 5° to 40°, for example. In the lighting fixture 1 of this embodiment, the inclination angle θ1 of the lamp 10 is configured to be 15°.

[0022] As described above, the socket 13 is disposed in an inclined position relative to the wall surface, and the lamp 10 is disposed in an inclined position relative to the wall surface, not horizontally. Therefore, the irradiation direction of the lamp 10 is inclined relative to the vertical direction of the wall surface. This allows the light distribution in the direction parallel to the wall surface to be increased compared to a case where the irradiation direction of the lamp 10 is mainly configured to be the front side (perpendicular to the wall surface). And, since the irradiation direction of the lamp 10 is inclined downward from the front side, the light distribution downward can be increased compared to a case where the irradiation direction of the lamp 10 is configured to be the front side. In the lighting fixture 1 of this embodiment, the inclination angle θ1 is set to 15°. The light irradiated from the lamp 10 is diffused and reflected within the housing 30, and is irradiated to the outside of the lighting fixture 1 through the upper panel 32 and the lower panel 33. At this time, the amount of light irradiated through the lower panel 33 is greater than that through the upper panel 32. The angle θ1 at which the irradiation direction of the lamp 10 is inclined with respect to the wall surface is not limited to this angle, and can be set to an appropriate angle according to the specifications. For example, if the socket mounting base 12 is provided so that the inclination angle θ1 is 30°, the amount of light irradiated through the lower panel 33 can be increased.

[0023] Mounting portion 12a of socket mounting base 12 is configured to be inclined relative to the wall surface, and socket 13 is arranged in an inclined position relative to the wall surface. Mounting portion 12a is configured to be inclined downward (diagonally downward) from the front side. Mounting portion 12a is configured so that inclination angle θ1 relative to the wall surface is in the range of, for example, 5° to 40°. In lighting fixture 1 of this embodiment, mounting portion 12a is configured so that inclination angle θ1 relative to the wall surface is 15°. Furthermore, in the lighting fixture 1 of this embodiment, the sensor unit 23 is disposed closer to the wall surface than the opening 31b on the underside of the side plate 31. In such a configuration, the light emitted from the lamp 10 disposed at an angle to the wall surface is irradiated through the opening 31b at an angle away from the wall surface. Therefore, the light of the lamp 10 is less likely to reach the sensor unit 23 than when the lamp 10 is disposed so that the irradiation direction is along the downward direction (parallel to the wall surface), and therefore it is possible to prevent malfunction caused by the sensor unit 23 detecting the light of the lamp 10.

[0024] As described above, the mounting portion 12a of the socket mounting base 12 is configured so that the socket 13 is disposed in an inclined position relative to the wall surface, and the irradiation direction of the lamp 10 is inclined relative to the wall surface. The inclination angle θ1 of the mounting portion 12a can be set to an appropriate angle according to the specifications. By changing the socket mounting base 12 to one having the mounting portion 12a with the desired inclination angle θ1 according to the specifications, the light distribution can be adjusted without changing the members constituting the fixture body 20 other than the socket mounting base 12.

[0025] As described above, socket 13 is disposed at an angle to the wall surface so that the mounting surface of socket 13 for lamp 10 faces downward rather than forward. This makes it easy to check the mounting surface of socket 13 for lamp 10 from the underside of lighting fixture 1 (the lower opening side of housing 30), facilitating the installation and removal of lamp 10.

[0026] As described above, the lower panel 33 is configured to be detachable from the side plate portion 31. Therefore, by removing the lower panel 33 from the side plate portion 31, the lamp 10 can be easily attached and detached from the lower side of the lighting fixture 1 (the lower opening side of the housing 30).
