[0010] Lighting fixture 11 is a long, moisture-proof and rain-proof lighting device that is installed on an installation surface such as a wall or ceiling. Lighting fixture 11 comprises a light source 20, a fixture body 21, and a cover 22. In lighting fixture 11, light source 20 itself has a moisture-proof and rain-proof structure, and by using this light source 20, no moisture-proof and rain-proof structure is required between fixture body 21 and cover 22, etc.

[0011] The light source 20 is long and has a moisture-proof and rain-proof structure. The light source 20 is housed in a sealed cylindrical enclosure that is optically transparent at least on the front side in the light emission direction. It contains a light source module (not shown) that is a light source unit having a plurality of light-emitting elements such as LEDs, and a power supply unit that converts external power input from the outside into a predetermined lighting power and supplies it to the plurality of light-emitting elements. A power supply wiring and an accessory wiring connected to the power supply unit are drawn out from the enclosure, and the power supply wiring is connected to a power line drawn into the fixture body 21 at the installation location. The power supply unit controls the lighting of the light source 20 by a signal input, for example, through the accessory wiring.

[0012] The fixture body 21 is formed into an elongated shape, for example, from a metal plate. The fixture body 21 is installed on an installation surface such as a wall or ceiling using screws, bolts, etc. The fixture body 21 is provided with a light source installation section for installing the light source 20. Installation sections 27 for installing the cover 22 with an installation fixture 23 are provided on both longitudinal ends of the fixture body 21. The installation fixture 23 is, for example, a decorative screw that can be held and turned with fingers, and the threaded section protruding from the head is inserted through the cover 22 and screwed into the installation section 27.

[0013] The cover 22 is formed into a long length from, for example, a milky white translucent resin material. The cover 22 is attached to the fixture body 21 installed on the installation surface so as to house the light source 20, and is detachably attached to the fixture body 21 by a mounting fixture 23.

[0014] The cover 22 is box-shaped and has a front portion 24, side portions 25 on both sides in the short direction of the front portion 24, and side portions 26 on both sides in the longitudinal direction of the front portion 24, and is open on the rear side that is attached to the fixture body 21. The side portions 26 on both sides in the longitudinal direction of the cover 22 have insertion holes through which the threaded portions of the mounting fixture 23 are inserted, at positions closer to the rear than the front portion 24 and closer to the fixture body 21. The side of one side portion 26 of the cover 22 is the side surface 11a of the lighting fixture 11 on which the external device 12 is arranged.

[0015] The external device 12 also includes a mounting plate 30 , a box-shaped housing 31 placed on the mounting plate 30 , and a fixture 32 for fixing the housing 31 to the mounting plate 30 .

[0016] The mounting plate 30 is formed from a flat metal plate, one end of which is fixed to the back side of the fixture body 21 by screws or the like, and the other end of which protrudes outward from the side surface 11a of the lighting fixture 11. In the area of ​​the mounting plate 30 which protrudes outward from the side surface 11a of the lighting fixture 11, a housing placement surface 34 on which the housing 31 is placed is formed.

[0017] The housing 31 is attached to the housing placement surface 34 of the mounting plate 30 so as to be rotatable about a rotation axis 35 in a direction parallel to the housing placement surface 34. The rotation axis 35 is, for example, a fastener such as a screw or a rivet. The rotation axis 35 is disposed on one side of a center line s that is perpendicular to the side surface 11a of the lighting fixture 11 and passes through the center of the mounting plate 30, at a position closer to the side of the mounting plate 30 that is parallel to the center line s than the center line s.

[0018] The pivot shaft 35 supports the housing 31 rotatably relative to the mounting plate 30 between a first position (position shown in Figures 4 and 5), which is a usage position in which the housing 31 faces the side surface 11a of the lighting fixture 11 and covers the side surface 11a of the lighting fixture 11, and a second position (position shown in Figure 2), which is an open position in which the side surface 11a of the lighting fixture 11 is open.

[0019] Mounting plate 30 is provided with a fixing portion 36 on the opposite side of center line s along which pivot shaft 35 is disposed, for fixing housing 31 to mounting plate 30 at a first position using fixing device 32. Fixing portion 36 is bent and raised from the other side of mounting plate 30 parallel to center line s toward housing placement surface 34. Fixing portion 36 is positioned outside of the rotation locus t of housing 31 rotating about pivot shaft 35, i.e., at a position that does not interfere with the rotating housing 31, and is positioned opposite the outer surface of housing 31 rotated to the first position. Fixing portion 36 is positioned closer to side surface 11a of lighting fixture 11 than pivot shaft 35. Fixing portion 36 is provided with an insertion hole 37 through which fixing device 32 is inserted.

[0020] The mounting plate 30 is provided with a temporary fixing hole 38 for temporary fixing, at a position on one side of the center line s away from the rotation axis 35 toward the tip end in the protruding direction of the mounting plate 30, to which the fixing device 32 can be detachably attached (screwed into). With the housing 31 rotated to the second position, the fixing device 32 is attached to the temporary fixing hole 38, whereby the housing 31 is temporarily fixed to the second position.

[0021] The housing 31 is formed in a rectangular box shape with an opening 40 on one side. The housing 31 includes a first surface 41 disposed on the mounting plate 30, a second surface 42 facing the first surface 41, a third surface 43 facing the opening 40 between the first surface 41 and the second surface 42, a fourth surface 44 on one side intersecting the opening 40 and the third surface 43 between the first surface 41 and the second surface 42, and a fifth surface 45 on the other side. A space for a storage section 46 for storing an accessory device is formed inside the housing 31. When the housing 31 is in the first position, the opening 40 of the housing 31 faces the side surface 11a of the lighting fixture 11.

[0022] The second surface portion 42, the third surface portion 43, the fourth surface portion 44, and the fifth surface portion 45, excluding the first surface portion 41, have window holes 47 in which accessory devices are placed, and a plurality of mounting holes 48 for attaching accessory devices are formed around the window holes 47.

[0023] The first surface 41, which is disposed on the housing mounting surface 34 of the mounting plate 30, is rotatably attached to the mounting plate 30 by a rotation shaft 35. The position of the rotation shaft 35 on the first surface 41 is closer to the fourth surface 44 than the fifth surface 45 in a direction parallel to the opening 40. The fifth surface 45 of the frame body 31 faces the fixing portion 36 when the frame body 31 is rotated to the first position. The fifth surface 45 is provided with a fixing hole 49, which is disposed coaxially with the insertion hole 37 of the fixing portion 36 and into which the fixing tool 32 inserted through the insertion hole 37 is fixed (screwed).

[0024] Fixing device 32 is a rivet or thread such as a screw, and in this embodiment, for example, a decorative screw that can be gripped with fingers and turned is used. Fixing device 32 is used both for fixing housing 31 to a first position via fixing portion 36, and for temporarily fixing housing 31 to a second position by attaching it to temporary fixing hole 38 of mounting plate 30.

[0025] The accessory device is inserted into the storage compartment 46 through the opening 40 of the housing 31 and accommodated therein. The accessory device has a moisture-proof and rain-proof structure. The accessory device's components, such as a sensor, camera, and emergency light, are arranged in any of the window holes 47 provided on the second surface 42 to the fifth surface 45 of the housing 31. The sensor, camera, and emergency light of the accessory device can be arranged in any of the window holes 47 depending on the orientation of the lighting fixture 11 installed on the wall or ceiling, the detection direction of the accessory device's sensor, the shooting direction of the camera, and the light emission direction of the emergency light, etc., allowing a single housing 31 to accommodate all of these. An outer cover may be detachably attached to the outside of the housing 31 accommodating the accessory device, covering the entire area except for the window holes 47 where the sensor, camera, and emergency light of the accessory device are arranged.

[0026] The accessory device may be connected to lighting fixture 11 by a cable to receive power from lighting fixture 11 or transmit signals to lighting fixture 11. The accessory device may also be equipped with a battery or may be connected to a power line separate from the power line connected to lighting fixture 11.

[0027] Next, the operation of the lighting device 10 will be described.

[0028] When installing lighting device 10 on an installation surface, as shown in Fig. 2, housing 31 of external device 12 is rotated to the second position to expose side surface 11a of lighting fixture 11. Fixing device 32 removed from fixing portion 36 is screwed into temporary fixing hole 38 of mounting plate 30, and housing 31 is temporarily fixed in the second position to prevent it from rotating to the first position. By temporarily fixing housing 31 in this way in the second position, it is possible to prevent housing 31 from rotating toward the first position during installation and hitting the worker's hand or getting pinched between lighting fixture 11 and the housing 31.

[0029] With the external device 12 in this state, the fixture body 21, with the cover 22 and light source 20 removed, is installed on the installation surface. The light source 20 is attached to the installed fixture body 21, and the power line leading into the fixture body 21 is connected to the light source 20. If a connection between the lighting fixture 11 side and the accessory device side is required, the necessary wiring work is performed. The cover 22 is attached to the fixture body 21 so as to accommodate the light source 20, the mounting fixture 23 is screwed into the mounting portion 27 of the fixture body 21 through the insertion hole in the side portion 26 of the cover 22, and the cover 22 is attached to the fixture body 21, and the lighting fixture 11 is assembled.

[0030] After assembling the lighting fixture 11, in the external device 12, the fixing device 32 screwed into the temporary fixing hole 38 of the mounting plate 30 is removed, and the housing 31 is rotated from the second position where the side surface 11a of the lighting fixture 11 is exposed to the first position where it faces the side surface 11a of the lighting fixture 11. The fixing device 32 is screwed into the fixing hole 49 of the housing 31 through the fixing portion 36 of the mounting plate 30, and the housing 31 is fixed to the mounting plate 30 in the first position.

[0031] When installing the lighting device 10 on a wall, by positioning the fixing portion 36 of the mounting plate 30 on the upper side of the mounting plate 30 and arranging it facing upward, the fixing device 32 is prevented from falling off even if the fixing portion 36 becomes loose. Furthermore, by positioning the fixing portion 36 of the mounting plate 30 on the lower side of the mounting plate 30 and arranging it facing downward, even if the lighting device 10 is installed at a high position on the wall, the fixing device 32 can be easily rotated from below, improving installation workability.

[0032] Furthermore, after the lighting device 10 is installed, when performing maintenance on the lighting fixture 11 or removing the lighting device 10 from the installation surface, the fixing device 32 is removed and the housing 31 is rotated from a first position facing the side surface 11a of the lighting fixture 11 to a second position that opens the side surface 11a of the lighting fixture 11, thereby making it possible to operate the mounting device 23 on the side surface 11a of the lighting fixture 11.

[0033] In this way, in external device 12, housing 31 in which accessory devices are placed can be rotated between a first position, which is a use position facing side surface 11a of lighting fixture 11 and covering side surface 11a of lighting fixture 11, and a second position, which is an open position that exposes side surface 11a of lighting fixture 11. This allows accessory devices to be externally attached to side surface 11a of lighting fixture 11, and housing 31 can be retracted to enable work on lighting fixture 11 from side surface 11a. This allows lighting fixtures 11 that do not use accessory devices and lighting fixtures 11 that use accessory devices to have a common structure.

[0034] The fixing portion 36 is located outside the rotation trajectory t of the housing 31 which rotates around the rotation axis 35, and therefore can fix the housing 31 which has rotated to the first position while preventing interference with the rotating housing 31.

[0035] The pivot axis 35 is arranged on one side of the center line s that is perpendicular to the side surface 11a of the lighting fixture 11 and passes through the center of the mounting plate 30, and the fixed part 36 is arranged on the other side, so that the housing 31 can be rotated widely, the side surface 11a of the lighting fixture 11 can be largely freed up, and work on the lighting fixture 11 from the side surface 11a can be easily performed.

[0036] The external device 12 can also be applied to cases where an accessory device is externally attached to an external object other than the lighting fixture 11, such as an air conditioner.

[0037] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
