Embodiments for Carrying Out the Invention

[0009] Hereinafter, an embodiment will be described with reference to the drawings.

[0010] Fig. 1 shows a lighting device 10. The lighting device 10 is a long base light, and is a ceiling direct-mount type lighting device that is directly mounted on, for example, a ceiling surface which is an installation surface. Note that the lighting device 10 may also be an embedded type lighting device embedded in the ceiling surface, a suspended type lighting device suspended from the ceiling surface, etc.

[0011] The lighting device 10 includes a long instrument body 11 installed on the ceiling surface, and a long light source unit 12 detachably attached to the lower surface side which is one surface intersecting the longitudinal direction of the instrument body 11.

[0012] Fig. 2 shows the instrument body 11. The instrument body 11 is made of metal and is formed in a long shape. The instrument body 11 has a long top plate portion 20, side plate portions 21 bent from both sides in the short direction intersecting the longitudinal direction of the top plate portion 20, and end plate portions 22 provided at both ends in the longitudinal direction of the top plate portion 20. A long accommodating portion 23 is formed inside the instrument body 11, and a long opening 24 communicating with the accommodating portion 23 is formed on the lower surface side. Note that the instrument body 11 may also be an inverted Fuji type having reflection plate portions on both sides in the short direction, a type with a cap having a cap protruding obliquely downward from the lower ends of the side plate portions on both sides, etc.

[0013] On the top plate portion 20 of the instrument body 11, a pair of mounting holes 25 for mounting to a pair of suspension bolts protruding from the ceiling surface, a wiring hole 26 for drawing a power line drawn from the ceiling surface into the instrument body 11, etc. are provided. The wiring hole 26 is provided near one end side in the longitudinal direction of the instrument body 11.

[0014] Inside the appliance body 11, a terminal block 28, a power supply unit 29, a first mounting member 30, and a second mounting member 31 are arranged. These terminal block 28, power supply unit 29, first mounting member 30, and second mounting member 31 are attached to the lower surface which is the inner surface of the top plate portion 20 of the appliance body 11 and are housed inside the housing portion 23.

[0015] The terminal block 28 is arranged between one end side from the center in the longitudinal direction of the appliance body 11 and the wiring hole 26. A power line drawn from the wiring hole 26 is electrically connected to the terminal block 28, and AC power which is external power supplied by the power line is input. The terminal block 28 and the power supply unit 29 are electrically connected by internal wiring wired inside the appliance body 11, and the input AC power is supplied to the power supply unit 29.

[0016] Also, the power supply unit 29 is arranged on the other end side in the longitudinal direction of the appliance body 11 rather than the terminal block 28. The power supply unit 29 converts the AC power supplied through the terminal block 28 into a predetermined lighting power and supplies it to the light source unit 12. A wire with a connector which is electrically connected to the light source unit 12 and supplies the lighting power is drawn out from the power supply unit 29.

[0017] Also, the first mounting member 30 is arranged on one end side in the longitudinal direction of the appliance body 11 at a position in contact with or close to the inner surface of the end plate portion 22. The first mounting member 30 is shown in FIGS. 4 to 6. The first mounting member 30 is integrally formed of metal. The first mounting member 30 includes an upper surface portion 33 attached to the lower surface of the top plate portion 20 of the appliance body 11 by screwing or the like, an end surface portion 34 bent from this upper surface portion 33 and arranged along the inner surface of the end plate portion 22 of the appliance body 11, a lower surface portion 35 bent from this end surface portion 34 and arranged along the opening portion 24 so as to be parallel to the lower surface (the surface of the opening portion 24) of the appliance body 11, a hooked portion 36 protruding from the center in the width direction (the width direction corresponding to the short side direction of the appliance body 11) on the tip side of this lower surface portion 35 toward the center side in the longitudinal direction of the appliance body 11, and inclined portions 37 rising obliquely from both sides in the width direction on the tip side of the lower surface portion 35 and from both sides of the hooked portion 36 toward the inside of the appliance body 11 and one end side of the appliance body 11.

[0018] The engaged portion 36 has a bent portion 38 which is a disengaging prevention portion bent upward from the tip side of the engaged portion 36.

[0019] The inclined portion 37 has both side rising portions 39 rising from both sides in the width direction of the lower surface portion 35, and a spring receiving surface portion 40 connecting the upper ends of these both side rising portions 39. The inclined portion 37 is provided with an inclined surface 37a on the surface facing the central side of the appliance body 11, and this inclined surface 37a is formed flush from both side rising portions 39 to the spring receiving surface portion 40. An inclined spring receiving surface 41 formed by the inclined surface 37a is provided on the spring receiving surface portion 40 of the inclined portion 37.

[0020] Also, Fig. 2 and Fig. 7 show the second attachment member 31. The second attachment member 31 is disposed on the other end side of the appliance body 11 at a position separated from the end plate portion 22 on the other end side of the appliance body 11 toward the central side of the appliance body 11, and is disposed at a position closer to the central side of the appliance body 11 than the first attachment member 30. The second attachment member 31 has a different shape from the first attachment member 31 and is integrally formed of metal. The second attachment member 31 has an upper surface portion 43 attached to the lower surface of the top plate portion 20 of the appliance body 11 by screwing or the like, and a spring receiving portion 44 bent downward from this upper surface portion 43. A hook hole 45 is provided in the spring receiving portion 44, and a hook protrusion 46 protrudes upward from the center in the width direction of the lower edge of this hook hole 45.

[0021] Next, Fig. 3, Fig. 5 to Fig. 7 show the light source unit 12. The light source unit 12 includes a long chassis 50, a long light source module 51 attached to the lower surface side of this chassis 50, and a light source cover 52 attached to the chassis 50 so as to cover this light source module 51. A first attachment spring 53 is attached to one end side in the longitudinal direction of the chassis 50, and a second attachment spring 54 is attached to the other end side.

[0022] The chassis 50 is made of metal and is provided in a long shape. The chassis 50 includes a long light source attachment portion 56, and side edge portions 57 rising upward from both sides in the short direction of this light source attachment portion 56.

[0023] The light source module 51 includes a long light source substrate 59 and a plurality of light emitting elements 60 mounted on the front surface side of the light source substrate 59. The light source substrate 59 is attached along the longitudinal direction of the chassis 50 such that the back side faces the light source attachment portion 56 of the chassis 50. As the light emitting elements 60, semiconductor light emitting elements such as LEDs or organic ELs are used. A wire with a connector that can be connected to the connector of the power supply unit 29 is connected to the light source module 51. The wire with a connector of the light source module 51 is drawn out to the upper surface side of the chassis 50.

[0024] The light source cover 52 is a resin-made translucent cover having translucency and light diffusing properties, and light from the light emitting elements 60 passes through it. The light source cover 52 is formed in a shape in which the cross-sectional shape in the short side direction protrudes in a convex curved surface shape toward the front side.

[0025] On the upper surface side of the light source cover 52, an opening for arranging the light source module 51 is provided along the longitudinal direction in the central region in the short side direction, and engaging portions 62 that engage with the side edge portions 57 on both sides of the chassis 50 are provided along the longitudinal direction in both side regions of the opening which are the both side regions in the short side direction. In addition, contact portions 63 that contact and are attached to the lower end portions of the side plate portions 21 on both sides of the instrument body 11 are provided along the longitudinal direction outside the engaging portions 62 in the short side direction. The chassis 50 and the light source cover 52 are integrally combined by sliding in the longitudinal direction.

[0026] An end face cover 64 is attached to the end of the light source cover 52. The end face cover 64 is made of resin and may be non-translucent or may have translucency. The end face cover 64 is attached to the end of the light source cover 52 integrally combined with the chassis 50 by sliding, and holds the light source cover 52 with respect to the chassis 50.

[0027] Further, the first mounting spring 53 and the second mounting spring 54 have the same shape, and the same parts (common parts) are used. By means of common spring mounting members 66, the first mounting spring 53 is attached to one end side in the longitudinal direction of the light source unit 12, and the second mounting spring 54 is attached to the other end side in the longitudinal direction of the light source unit 12, respectively.

[0028] The spring mounting member 66 is formed of, for example, a metal plate. The spring mounting member 66 includes a mounting plate portion 67 disposed on the light source mounting portion 56 of the chassis 50, side plate portions 68 that are bent upward from both sides in the width direction of the mounting plate portion 67 and are attached to the inside of the side edge portions 57 on both sides of the chassis 50, and an enclosing portion 69 that is bent in a substantially reverse U shape outward in the width direction from the upper end side of the side plate portion 68 and surrounds the side edge portion 57 of the chassis 50 and the engaging portion 62 of the light source cover 52. On the edge side of each mounting plate portion 67 located on the central side in the longitudinal direction of the light source unit 12, a pair of spring mounting portions 70 that are cut and raised in a substantially reverse U shape for holding the mounting springs 53 and 54 are provided side by side in the width direction.

[0029] Each of the mounting springs 53 and 54 is constituted by a torsion spring formed of a single spring wire. Each of the mounting springs 53 and 54 includes a pair of coil portions 72 formed by winding both ends of the spring wire in a coil shape, a pair of arm portions 73 that are intermediate portions of the spring wire and extend from one end side of the pair of coil portions 72, a hook portion 74 provided between the tips of the pair of arm portions 73, and a pair of end portions 75 that are both ends of the spring wire and protrude from the other end side of the pair of coil portions 72.

[0030] The pair of coil portions 72 are inserted into and attached to the pair of spring mounting portions 70 of the spring mounting member 66, and the pair of end portions 75 are inserted into and fixed to the spring mounting member 66. These coil portions 72 and end portions 75 are configured as spring bases 76 that are attached to the light source unit 12 via the spring mounting member 66.

[0031] The first mounting spring 53 is arranged such that the hook portion 74 faces one end side in the longitudinal direction of the light source unit 12, and the spring base portion 76 is attached to one end side of the light source unit 12 via the spring mounting member 66. The second mounting spring 54 is arranged such that the hook portion 74 faces the other end side in the longitudinal direction of the light source unit 12, and the spring base portion 76 is attached to the other end side of the light source unit 12 via the spring mounting member 66.

[0032] The first mounting spring 53 and the second mounting spring 54 are attached at positions asymmetric with respect to the center in the longitudinal direction of the light source unit 12. The first mounting spring 53 is attached at a position closer to the end side of the light source unit 12 with respect to the center in the longitudinal direction of the light source unit 12 than the second mounting spring 54. Specifically, the first mounting spring 53 is attached such that the hook portion 74 at the tip side of the arm portion 73 is located in a region that protrudes from one end side in the longitudinal direction of the chassis 50 and overlaps above the end face cover 64 (see FIG. 5). Also, the second mounting spring 54 is attached such that the hook portion 74 at the tip side of the arm portion 73 is located in a region that overlaps above the chassis 50 without protruding from the other end side in the longitudinal direction of the chassis 50 (see FIG. 7).

[0033] A spring force is applied to the arm portions 73 of the respective mounting springs 53 and 54 in a rotational direction in which the hook portion 74 at the tip side of the arm portion 73 approaches the upper surface side of the light source unit 12 by the coil portion 72 attached to the spring mounting member 66.

[0034] At least the first mounting spring 53 is configured such that, in a state of being removed from the first mounting member 30, the rotation of the arm portion 73 due to the spring force is restricted at a position separated from the light source unit 12 so that a predetermined gap is formed between the hook portion 74 and the upper surface of the light source unit 12. For example, the rotation of the arm portion 73 due to the spring force is restricted by the contact between the base end side of the arm portion 73 and the spring mounting member 66 or another restricting member. Also, for the second mounting spring 54, the hook portion 74 may contact the upper surface side of the light source unit 12, or may be restricted at a position separated from the upper surface of the light source unit 12 in the same manner as the first mounting spring 53.

[0035] Next, the installation of the lighting device 10 will be described.

[0036] Pull the power line drawn from the ceiling surface into the appliance body 11 through the wiring hole 26, screw nuts through the pair of mounting holes 25 of the appliance body 11 onto the pair of suspension bolts protruding from the ceiling surface, and install the appliance body 11 on the ceiling surface. The power line is connected to the terminal block 28.

[0037] As shown in FIG. 5, with one end side in the longitudinal direction of the light source unit 12 directed obliquely upward, while inserting the arm portion 73 of the first mounting spring 53, the side edge portion 57 of the chassis 50, the engaging portion 62 of the light source cover 52, etc. into the opening 24 of the appliance body 11, hook the engaging portion 74 of the first mounting spring 53 onto the engaged portion 36 of the first mounting member 30.

[0038] Lift the arm portion 73 of the second mounting spring 54 at the other end side in the longitudinal direction of the light source unit 12, insert the tip side of the arm portion 73 into the engaging hole 45 of the second mounting member 31 at the other end side in the longitudinal direction of the appliance body 11, and hook the engaging portion 74 of the second mounting spring 54 onto the engaging projection 46 of the second mounting member 31.

[0039] In this state, one end side in the longitudinal direction of the light source unit 12 is temporarily suspended (temporarily attached) to one end side of the appliance body 11 by the first mounting spring 53, and the other end side in the longitudinal direction of the light source unit 12 is temporarily suspended to the other end side of the appliance body 11 by the second mounting spring 54. In this temporarily suspended state of the light source unit 12, there is a gap through which a hand can be inserted and operated between the other end side in the longitudinal direction of the light source unit 12 and the other end side in the longitudinal direction of the appliance body 11. Through this gap, connect the wired connector from the power supply unit 29 and the wired connector from the light source module 51 by connector connection.

[0040] While moving the light source unit 12 so as to push it into the appliance body 11 on one end side in the longitudinal direction, push up the other end side in the longitudinal direction of the light source unit 12 upward.

[0041] By operating to move the light source unit 12 so as to be pushed into one end side in the longitudinal direction with respect to the instrument body 11, as shown in FIGS. 5 to 6, the engaging portion 74 of the first mounting spring 53 that moves to one end side in the longitudinal direction with respect to the instrument body 11 abuts against the inclined surface 37a of the inclined portion 37 from the engaged portion 36. After the abutment, the engaging portion 74 slides upward along the inclined surface 37a of the inclined portion 37. By the engaging portion 74 sliding upward along the inclined surface 37a of the inclined portion 37, one end side of the light source unit 12 is pulled upward via the first mounting spring 53. However, since one end side in the longitudinal direction of the contact portions 63 on both sides of the light source unit 12 and the end face cover 64 or the like abut against the lower portions of the side plate portions 21 on both sides of the instrument body 11 and the pulling up is restricted, the first mounting spring 53 elastically deforms so that a space opens between the tip side of the arm portion 73 of the first mounting spring 53 and the upper surface of the light source unit 12. As shown in FIG. 6, in the state where the light source unit 12 is attached to the instrument body 11, the engaging portion 74 stops in a state of abutting against the inclined spring receiving surface 41 which is the inclined surface 37a of the inclined portion 37. In this attached state, a spring force for pulling up the light source unit 12 with respect to the first attachment member 30 and a spring force for pushing the light source unit 12 toward the other end side in the longitudinal direction with respect to the first attachment member 30 act on the first mounting spring 53. Due to the spring force of the first mounting spring 53 for pulling up the light source unit 12 with respect to the first attachment member 30, one end side of the light source unit 12 is pulled up by the instrument body 11.

[0042] On the other hand, by operating to push up the other end side in the longitudinal direction of the light source unit 12, as shown in FIG. 7, the arm portion 73 of the second mounting spring 54 is inserted into the engaging hole 45 of the second attachment member 31, so that a spring force for pulling up the light source unit 12 with respect to the second attachment member 31 acts on the instrument body 11, and the other end side of the light source unit 12 is pulled up by the instrument body 11.

[0043] Then, at one end side and the other end side in the longitudinal direction of the light source unit 12, with the side edge portion 57 of the chassis 50 protruding on the upper surface side of the light source unit 12 and the engaging portion 62 of the light source cover 52 or the like inserted into the opening 24 of the instrument body 11, the light source unit 12 is attached to the instrument body 11.

[0044] Also, when removing the light source unit 12 from the appliance main body 11, by pulling downward against the spring force of the second mounting spring 54 at the other end side in the longitudinal direction of the light source unit 12 to lower it, the engaging portion 74 of the second mounting spring 54 is hooked on the second mounting member 31 and temporarily suspended with respect to the appliance main body 11. Further, due to the spring force of the first mounting spring 53, the light source unit 12 moves to the other end side in the longitudinal direction, and the engaging portion 74 of the first mounting spring 53 abuts against the inclined portion 37 and then shifts to a state of being hooked on the inclined portion 36 and is temporarily suspended with respect to the appliance main body 11. Disconnect the connector connection between the connector-equipped wiring from the power supply unit 29 and the connector-equipped wiring from the light source module 51 through the gap between the light source unit 12 and the appliance main body 11. By removing the light source unit 12 from the second mounting member of the second mounting spring 54 and removing the engaging portion 74 of the first mounting spring 53 from the engaged portion 36 of the first mounting member 30, the light source unit 12 can be removed from the appliance main body 11.

[0045] In the lighting device 10 configured as described above, when the engaging portion 74 of the first mounting spring 53 comes into contact with the inclined spring receiving surface 41 of the inclined portion 37 from the state of being hooked on the engaged portion 36 of the first mounting member 30, the light source unit 12 is attached to the appliance main body 11. Therefore, it is possible to attach the light source unit 12 to the appliance main body 11 and hold it in the longitudinal direction.

[0046] Even if the shapes of the first mounting member 30 and the second mounting member 31 of the appliance main body 11 are different and the mounting method on the mounting spring side with respect to the first mounting member 30 and the mounting method on the mounting spring side with respect to the second mounting member 31 are different, it is possible to cope with different shapes and different mounting methods using the mounting springs 53 and 54 of the same shape.

[0047] In order for the engaging portion 74 of the first mounting spring 53 to come into contact with the inclined spring receiving surface 41 of the inclined portion 37 from the state of being hooked on the engaged portion 36 of the first mounting member 30, the light source unit 12 is pushed into the one end side in the longitudinal direction during the mounting operation, so that it is possible to suppress the light source unit 12 from swinging or shifting in the longitudinal direction and improve the workability.

[0048] In addition, since the hook portion 74 of the first mounting spring 53 is separated from the light source unit 12 in a state of being removed from the first mounting member 30, the hook portion 74 can be hooked onto the hooked portion 36 of the first mounting member 30 without performing an operation such as causing the first mounting spring 53, improving workability.

[0049] Further, since the first mounting spring 53 is positioned closer to the end portion side of the light source unit 12 than the second mounting spring 54 with respect to the center in the longitudinal direction of the light source unit 12, it is possible to facilitate hooking the hook portion 74 of the first mounting spring 53 onto the first mounting member 30, improving workability.

[0050] Although some 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 implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
