[Figure 5] This is a perspective view of a portion of the light source section of the same lighting device in a temporarily suspended state. [Modes for carrying out the invention]

[0008] The first embodiment will be described below with reference to Figures 1 to 3.

[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 3, 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 spring receiving member 26 is attached to one end of the main body portion 11 in the longitudinal direction. As shown in Figure 3, the spring receiving member 26 has a mounting portion 27 that is attached to the lower surface of the mounting plate portion 15 of the main body portion 11 by screw fastening, a spring receiving portion 28 that is bent downward from the mounting portion 27, a hooking hole 29 provided on the inside of the spring receiving portion 28, and a hooking projection 30 that protrudes into the hooking hole 29 from the center of the lower edge of the hooking hole 29.

[0014] Furthermore, the light source unit 12 includes a chassis 40, a light source module 41 which is a light source attached to the lower side of the chassis 40 (hereinafter, the vertical direction of the light source unit 12 will be described based on the orientation when it is positioned on the main body unit 11), and a cover 42 which covers the light source module 41 and is attached to the chassis 40.

[0015] The chassis 40 is made of metal and is formed in an elongated shape. The chassis 40 has an elongated mounting plate portion 43 and side wall portions 44 that rise up from both sides in the short direction of the mounting plate portion 43 toward the rear side of the chassis 40. Multiple 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.

[0016] The light source module 41 has a long circuit board and multiple light-emitting elements, such as LEDs, mounted along this circuit board. Wiring with a connector for receiving power to light up is connected to the light source module 41, and this wiring is brought out to the outside from one end of the rear of the chassis 40.

[0017] The cover 42 has a cover portion 46 with a convex curved surface facing the light source module 41, and end face portions 47 that close both end faces of the cover portion 46. The cover portion 46 is made of resin and has light transmittance and diffusibility for the 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 against the lower surface side of the chassis 40. The end face portions 47 may or may not have light transmittance.

[0018] Also, a mounting spring 50 is attached to one end side in the longitudinal direction on the upper surface side of the chassis 40 of the light source unit 12. The mounting spring 50 is attached to the chassis 40 by a mounting member 51. The mounting member 51 is attached to the chassis 40 by being engaged with the mounting holes 45 in the side wall portions 44 on both sides.

[0019] The mounting spring 50 is, for example, composed of a torsion spring, a pair of coil portions 52 are held by the mounting member 51, and a substantially U-shaped hook portion 53 connecting between one end portions of the pair of coil portions 52 extends toward the end side in the longitudinal direction of the light source unit 12. The other end portions of the pair of coil portions 52 are attached to the mounting member 51. The mounting spring 50 is arranged such that a spring force acts in a direction in which the hook portion 53 goes from the upper side of the chassis 40 through the end side to the lower side. Then, the mounting spring 50 is inserted into the hook hole 29 of the spring receiving member 26 of the main body portion 11 and hooked on the hook protrusion 30 in a state where the hook portion 53 is pulled up from the chassis 40 against the spring force, thereby temporarily suspending the light source unit 12 with respect to the main body portion 11. Further, when the light source unit 12 is pushed up, the light source unit 12 is pulled up by the spring force of the mounting spring 50 and attached to the main body portion 11, and is configured to hold the attached state.

[0020] Note that the mounting spring 50 is not limited to a torsion spring, and a leaf spring or the like may be used. Also, the mounting spring 50 may be attached to the main body portion 11, and the spring receiving member 26 may be attached to the light source unit 12.

[0021] Further, a magnet part (first magnet part) 60 is attached to the other end side in the longitudinal direction on the upper surface side of the chassis 40 of the light source unit 12. The magnet part 60 is detachably attached by being adsorbed by magnetic force to the lower surface of the mounting plate part 15 of the main body part 11.

[0022] The magnet part 60 has a cylindrical magnet 61 and a pair of adsorption members 62 for holding the magnet 61. The pair of adsorption members 62 are attached to a mounting plate 63 by screwing, and the mounting plate 63 is attached to the chassis 40. The axial direction of the cylindrical magnet 61 faces the short side direction of the chassis 40, and the magnet 61 is sandwiched and held by the pair of adsorption members 62 from both sides in the axial direction. The adsorption members 62 are made of a ferromagnetic metal, stand up in a direction perpendicular to the upper surface of the chassis 40, the tip part protrudes above the magnet 61 and also protrudes above the upper surface of the light source unit 12, and this tip part is brought into contact with the lower surface of the mounting plate part 15 of the main body part 11 and is adsorbed and attached by the magnetic force of the magnet 61. The mounting plate 63 is arranged between the side wall parts 44 on both sides of the chassis 40, and the protruding parts 64 protruding from both sides are inserted into the mounting holes 45 of the side wall parts 44 and attached to the chassis 40.

[0023] Next, the installation of the lighting device 10 will be described.

[0024] As shown in FIG. 3, the main body part 11 is installed on the ceiling surface.

[0025] Pull up the hook part 53 of the mounting spring 50 at one end side in the longitudinal direction of the light source unit 12 against the spring force, insert it into the hook hole 29 of the spring receiving member 26 of the main body part 11, and hook it on the hook protrusion 30. In this state, the light source unit 12 is in a state of being temporarily suspended from the main body part 11 via the mounting spring 50. In the temporarily suspended state of the light source unit 12, the wiring from the power supply unit 23 and the wiring from the light source module 41 are connected by a connector.

[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, with one end of the light source unit 12 acting as a pivot point. The main body unit 11 and the light source unit 12 are positioned by fitting the side wall portion 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, into the opening 19 of the main body unit 11.

[0027] The magnet part 60 contacts the lower surface of the mounting plate part 15 of the main body part 11, and the magnetic force of the magnet part 60 attracts the light source part 12 to the mounting plate part 15, attaching the other end of the light source part 12 to the main body part 11.

[0028] As a result, the mounting spring 50 and the magnet 60 attach both ends of the long light source unit 12 in the longitudinal direction to the main body unit 11.

[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 magnet unit 60, and the magnet unit 60 is pulled downward from the mounting plate 15 of the main body unit 11.

[0030] The mounting spring 50 connected to the main body 11 is used as a pivot point to rotate the other end of the light source unit 12 downwards, thereby temporarily suspending the light source unit 12 from the main body 11 via the mounting spring 50 (see Figure 3). 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 disconnected via connectors.

[0031] The hook portion 53 of the mounting spring 50 is detached from the hook projection 30 of the spring receiving member 26 and removed from the hook hole 29, and the light source unit 12 is detached from the main body unit 11.

[0032] Thus, in the lighting device 10 of this embodiment, by using both a mounting spring 50 and a magnet 60 to attach the main body 11 and the light source unit 12, the light source unit 12 can be easily attached and detached, and the light source unit 12 can be temporarily suspended from the main body 11, making wiring work easier and improving ease of installation.

[0033] Furthermore, if the magnet part 60 of the light source unit 12 falls off the main body unit 11, for example, if the user releases their hand from the light source unit 12 before securely attaching the magnet part 60 to the main body unit 11 during installation, the mounting spring 50 will catch on the spring receiving member 26, thus preventing the light source unit 12 from falling. Because the mounting spring 50 has a fall prevention function, there is no need to use a separate fall prevention structure, which reduces the number of parts and improves ease of installation.

[0034] The spring receiving member 26 may be provided on the light source unit 12, and the mounting spring 50 may be provided on the main body unit 11. Also, the magnet unit 60 may be provided on either the main body unit 11 or the light source unit 12.

[0035] Next, Figures 4 and 5 show a second embodiment.

[0036] The second embodiment differs from the first embodiment in the configuration of the spring receiving member 26 and the mounting spring 50, but the other configurations are the same.

[0037] The spring receiving member 26 is positioned at one end of the main body portion 11. The spring receiving member 26 has a hooked portion 70 with a roughly L-shaped cross-section that protrudes from the longitudinal end side of the main body portion 11 toward the center, and mounting portions 71 that are located on both sides of the hooked portion 70 and protrude upward from the end side of the main body portion 11.

[0038] The mounting spring 50 has a coil portion 52 and a hook portion 53, and is attached to the chassis 40 of the light source unit 12 by a mounting member 51.

[0039] Then, during the installation of the lighting device 10, the light source unit 12, on which the mounting spring 50 is located, is raised to an oblique position, and one end of the light source unit 12 is moved diagonally upward toward the spring receiving member 26 located on one end of the main body unit 11, and the hooking portion 53 of the mounting spring 50 is hooked onto the hooked portion of the spring receiving member (see Figure 5). In this state, the light source unit 12 is temporarily suspended from the main body unit 11 via the mounting spring 50. 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 using connectors.

[0040] The other end of the light source unit 12, which is on the lower side, is rotated upward toward the main body 11, using one end of the light source unit 12 as a pivot point, while moving the light source unit 12 toward the one end. The hook portion 53 of the mounting spring 50 elastically deforms and rides up onto the mounting portion 71 of the spring receiving member 26, and the spring force pulls the light source unit 12 toward the fixture body 11.

[0041] The main body 11 and the light source unit 12 are positioned by fitting the side wall portion 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, into the opening 19 of the main body 11.

[0042] The magnet part 60 contacts the lower surface of the mounting plate part 15 of the main body part 11, and the magnetic force of the magnet part 60 attracts the light source part 12 to the mounting plate part 15, attaching the other end of the light source part 12 to the main body part 11.

[0043] As a result, the mounting spring 50 and the magnet 60 attach both ends of the long light source unit 12 in the longitudinal direction to the main body unit 11.

[0044] Thus, in the lighting device 10 of the second embodiment, by using the mounting spring 50 and the magnet 60 in combination to attach the main body 11 to the light source 12, the light source 12 can be easily attached and detached, the light source 12 can be temporarily suspended from the main body 11 to facilitate wiring work, the light source 12 can be prevented from falling, and the ease of installation can be improved.

[0045] In each embodiment, a second magnetic part may be placed between the mounting spring 50 and the magnet part 60 to magnetically attach the main body 11 and the light source 12. By placing this second magnetic part, the holding force of the light source 12 to the main body 11 can be strengthened.

[0046] 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]
