[0008] One embodiment will be described below with reference to the drawings.

[0009] Figures 1 and 2 show the lighting device 10. The lighting device 10 is a long base light and is a surface-mounted lighting device that is directly attached to the installation surface, such as the ceiling.

[0010] The lighting device 10 comprises a long main body (fixture body) 11 installed on the ceiling surface, and a long light source unit 12 that is detachably attached to the main body 11.

[0011] As shown in Figures 1 to 4, the main body 11 is formed in a long shape from a ferromagnetic metal plate. The main body 11 has a long top plate portion which is a mounting plate portion 15, side plate portions 16 that are bent downward from both sides in the short direction intersecting the longitudinal direction of the mounting plate portion 15, and end plate portions 17 that are located at both ends in the longitudinal direction of the mounting plate portion 15. A long storage portion 18 is formed inside the main body 11, and a long opening 19 that communicates with the storage portion 18 is formed on the lower side. Mounting holes 20 (see Figure 5) for mounting to the ceiling surface are provided near both ends of the mounting plate portion 15, and a wiring hole 21 for drawing in power lines from the outside is provided at one end of the mounting plate portion 15.

[0012] The main body 11 has a terminal block 22 and a power supply unit 23 attached to the underside of the mounting plate 15. Power lines drawn in from the wiring holes 21 are connected to the terminal block 22. The power supply unit 23 is electrically connected to the terminal block 22 by wiring and converts the AC power, which is external power supplied by the power lines, into a predetermined DC power for lighting and supplies it to the light source unit 12. Wiring with a connector that supplies lighting power is drawn out from the power supply unit 23.

[0013] Furthermore, a hinge portion 26 is attached to one end of the main body portion 11. As shown in Figure 5, the hinge portion 26 has a main body mounting portion 27 that is attached to the main body portion 11, a light source mounting portion 28 for attaching the light source portion 12, and a hinge shaft 29 that rotatably connects the main body mounting portion 27 and the light source mounting portion 28. At least the light source mounting portion 28 is made of a ferromagnetic metal.

[0014] The main body mounting portion 27 has a fixing portion 31 positioned on the lower surface of the mounting plate portion 15 of the main body portion 11 and fixed by a plurality of screws 30 inserted from the upper surface side of the mounting plate portion 15, a support portion 32 bent at approximately a right angle from the fixing portion 31 and positioned along the inside of the end plate portion 17 of the main body portion 11, and a pair of bearing portions 33 provided by bending in an arc shape from both sides of the lower end of the support portion 32. The fixing portion 31 is provided with a groove portion 31a that is cut out in a shape corresponding to the mounting hole 20. The light source mounting portion 28 has a rectangular, flat plate-shaped object to be attached (first object to be attached) 34, a bent portion 35 bent in approximately an L shape from one side of the object to be attached 34, and a bearing portion 36 provided by bending in an arc shape from the tip of the bent portion 35. The bearing portion 36 of the light source mounting portion 28 is positioned between a pair of bearing portions 33 of the main body mounting portion 27, and a hinge shaft 29 is positioned through these bearing portions 33 and 36, so that the light source mounting portion 28 is rotatably connected to the main body mounting portion 27 around the hinge shaft 29. The width of the hinge portion 26 in the direction corresponding to the short side of the main body portion 11 is narrower than the width of the opening 19, allowing the light source mounting portion 28 to rotate vertically through the opening 19.

[0015] Further, the light source unit 12 includes a chassis 40, a light source module 41 which is a light source attached to the lower surface side of the chassis 40 (hereinafter, the vertical direction of the light source unit 12 will be described based on the posture in the state where it is arranged on the main body unit 11), and a cover 42 attached to the chassis 40 so as to cover the light source module 41.

[0016] The chassis 40 is made of metal and is formed in a long shape. The chassis 40 has a long mounting plate portion 43 and side wall portions 44 that are raised from both sides in the short direction of the mounting plate portion 43 to the back side of the chassis 40. A plurality of slit-shaped mounting holes 45 that are long in the longitudinal direction of the chassis 40 are provided in the side wall portions 44 on both sides.

[0017] The light source module 41 has a long substrate and a plurality of light emitting elements such as LEDs mounted along the substrate. A wiring with a connector for receiving lighting power is connected to the light source module 41, and this wiring is drawn out to the outside from one end side of the back surface of the chassis 40.

[0018] The cover 42 has a convex curved surface-shaped cover portion 46 facing the light source module 41 and end surface portions 47 that close both end surfaces of the cover portion 46. The cover portion 46 is made of resin and has light transmittance and diffusibility of light from the light source module 41. The cover portion 46 has an engaging portion 48 that engages with the upper sides of the side wall portions 44 on both sides of the chassis 40 in a state where a part of the cover portion 46 abuts on the lower surface side of the chassis 40. The end surface portion 47 may or may not have light transmittance.

[0019] Also, a first magnet portion 51 is attached to one end side in the longitudinal direction on the back side of the chassis 40 of the light source unit 12, and a second magnet portion 52 is attached to the other end side. The first magnet portion 51 is detachably attached by magnetic force to the attracted portion 34 of the light source attachment portion 28 of the hinge portion 26, and the second magnet portion 52 is detachably attached by magnetic force to the lower surface (second attracted portion) of the attachment plate portion 15 of the main body unit 11.

[0020] The first magnet part 51 has a cylindrical magnet 53 and a cup-shaped adsorption member 54 that houses the magnet 53. It is attached to the mounting plate 56 with a screw 55 and is attached to the chassis 40 by this mounting plate 56. The first magnet part 51 is attached to the chassis 40 with the axial directions of the cylindrical magnet 53 and the adsorption member 54 facing in a direction perpendicular to the upper surface of the chassis 40, and is protrudingly arranged above the upper surface of the light source part 12. The adsorption member 54 is made of a ferromagnetic metal, and the opening edge part is brought into contact with the adsorption part 34 of the light source mounting part 28 of the hinge part 26 so as to be adsorbed by the magnetic force of the magnet 53. The mounting plate 56 is arranged between the side wall parts 44 on both sides of the chassis 40, and the protrusions 57 protruding from both sides are inserted into the mounting holes 45 of the side wall parts 44 and attached to the chassis 40.

[0021] The second magnet part 52 has a cylindrical magnet 58 and a pair of adsorption members 59 that hold the magnet 58. The pair of adsorption members 59 are screwed to the mounting plate 60 and are attached to the chassis 40 by this mounting plate 60. The axial direction of the cylindrical magnet 58 faces the short side direction of the chassis 40, and this magnet 58 is sandwiched and held by the pair of adsorption members 59 from both sides in the axial direction. The adsorption members 59 are made of a ferromagnetic metal, are erected in a direction perpendicular to the upper surface of the chassis 40, the tip parts protrude above the magnet 58 and also protrude above the upper surface of the light source part 12, and the tip parts are brought into contact with the lower surface of the mounting plate part 15 of the main body part 11 so as to be adsorbed by the magnetic force of the magnet 58. The mounting plate 60 is arranged between the side wall parts 44 on both sides of the chassis 40, and the protrusions 61 protruding from both sides are inserted into the mounting holes 45 of the side wall parts 44 and attached to the chassis 40.

[0022] Next, the construction of the lighting device 10 will be described.

[0023] As shown in FIG. 3, the main body part 11 is installed on the ceiling surface. In the installed state of this main body part 11, the light source mounting part 28 of the hinge part 26 hangs down by its own weight and protrudes downward from the opening 19.

[0024] The first magnet portion 51, which is one end of the light source unit 12 in the longitudinal direction, is positioned on the upper side, and the second magnet portion 52, which is the other end, is positioned on the lower side, and as shown in Figure 4, the first magnet portion 51 is brought into contact with the adsorption portion 34 of the light source mounting portion 28 of the hinge portion 26, and the light source mounting portion 28 is attached by the magnetic force of the first magnet portion 51.

[0025] With the first magnet unit 51 attached to the hinge unit 26, the light source unit 12 is temporarily suspended from the main body unit 11 via the hinge unit 26. With the light source unit 12 temporarily suspended, the wiring from the power supply unit 23 and the wiring from the light source module 41 are connected via connectors.

[0026] The other end of the light source unit 12, which is on the lower side, is rotated upward toward the main body unit 11, using the hinge 26 as a pivot point. The side wall 44 of the chassis 40 and the engaging portion 48 of the cover 42, which protrude from the upper surface of the light source unit 12, enter and fit into the opening 19 of the main body unit 11, thereby positioning the assembled posture of the main body unit 11 and the light source unit 12.

[0027] The second magnet portion 52 contacts the lower surface of the mounting plate portion 15 of the main body portion 11, and the mounting plate portion 15 is attached by the magnetic force of the second magnet portion 52.

[0028] As a result, the light source unit 12 is attached to the main body unit 11 by the first magnet unit 51 and the second magnet unit 52.

[0029] On the other hand, when removing the light source unit 12 from the main body unit 11, the other end of the light source unit 12 is pulled down against the magnetic attraction force of the second magnet unit 52, and the second magnet unit 52 is pulled downward from the mounting plate unit 15 of the main body unit 11.

[0030] The other end of the light source unit 12 is rotated downward using the hinge 26 as a pivot point, and the light source unit 12 is temporarily suspended from the main body unit 11 via the hinge 26 (see Figure 4). With the light source unit 12 temporarily suspended, the connectors from the power supply unit 23 and the light source module 41 are disconnected.

[0031] The first magnet part 51 is detached from the attached part 34 of the light source mounting part 28 of the hinge part 26 by resisting the magnetic attraction force of the first magnet part 51 (see Figure 3).

[0032] Thus, in the lighting device 10 of this embodiment, the first magnet part 51 and the second magnet part 52 allow the light source part 12 to be easily attached to and detached from the main body part 11. Furthermore, by using the hinge part 26, the light source part 12 can be temporarily suspended from the main body part 11 while wiring work is performed, thereby improving ease of installation.

[0033] A hinge portion 26 is provided on the main body portion 11, and the light source portion 11 is attached to this hinge portion 26 by the magnetic force of the first magnet portion 51. This configuration allows the main body portion 11 to bear the load associated with the rotation of the hinge portion 26, making it less likely for the load to be applied to the light source portion 12, thereby protecting the light source module 41 of the light source portion 12.

[0034] The hinge portion 26 may be provided on the light source portion 12, and the first magnet portion 51 may be provided on the main body portion 11. The second magnet portion 52 may be provided on either the main body portion 11 or the light source portion 12.

[0035] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
