The appliance body 11 includes a top plate portion 20, side plate portions 21 on both sides bent from both sides in the short direction (also referred to as the width direction) intersecting the longitudinal direction of the top plate portion 20, reflecting plate portions 22 on both sides protruding obliquely upward from the lower ends of these side plate portions 21, and end plate portions 23 closing both ends in the longitudinal direction, and is formed in a so-called inverted Fuji shape. An opening 24 is formed on the lower surface between the top plate portion 20, the side plate portions 21 on both sides, and the end plate portions 23 at both ends, and a concave accommodating portion 25 is formed inside. Note that the appliance body 11 is not limited to the inverted Fuji shape, and may be a trough shape without the reflecting plate portion 22, or a hat-shaped type having a hat protruding obliquely downward from the lower ends of the side plate portions 21 on both sides.

[0012] A plurality of mounting holes 26 for attaching to two suspension bolts protruding from the ceiling structure are provided on both end sides in the longitudinal direction of the top plate portion 20. A wiring hole 28 for drawing a power line 27 drawn from the ceiling surface side into the accommodating portion 25 of the appliance body 11 is provided at the center in the longitudinal direction of the top plate portion 20.

[0013] The power line 27 supplies, for example, AC power which is external power from a commercial AC power supply. As shown in Figs. 2 and 7, a cable called, for example, an F cable in which a plurality of electric wires 27c each having a single-core wire (conductor) 27a covered with a covering material 27b are collectively covered with an outer skin 27d is used for the power line 27. The power line 27 includes at least two electric wires 27c for power supply, and may further include one electric wire 27c for grounding. Such a power line 27 has characteristics of being strong and difficult to bend.

[0014] In addition, a terminal block 29 for connecting the power line 27 and spring receiving members 30 which are a pair of main body side mounting portions for attaching the light source unit 12 are attached to the appliance body 11.

[0015] The terminal block 29 is shown in FIGS. 2, 3, 5 to 7. On the upper surface side, which is one side facing the top plate portion 20 (wiring hole 28) of the appliance main body 11, a power cord connection portion 32 into which the power cord 27 is inserted and electrically connected is provided. On the lower surface side, which is the opposite side, a terminal block side energization portion 33 electrically connected to the power cord connection portion 32 is provided.

[0016] The terminal block 29 has a terminal block case 34, a plurality of wire connection terminals (not shown) arranged in the terminal block case 34, and a plurality of blade receiving terminals 35 (see FIG. 7) each electrically connected to each of the wire connection terminals.

[0017] The terminal block case 34 is made of an insulating resin and is provided in a rectangular parallelepiped shape. The power cord connection portion 32 on the upper surface side of the terminal block case 34 is provided with a plurality of wire insertion holes 36 into which each wire 27c of the power cord 27 is inserted. Inside each of these wire insertion holes 36, wire connection terminals electrically connected to the core wire 27a of the wire 27c of the power cord 27 are arranged. The wire insertion holes 36 are provided along a direction perpendicular to the upper surface of the terminal block case 34, and the wire 27c of the power cord 27 is inserted from a direction perpendicular to the upper surface of the terminal block 29. The plurality of wire insertion holes 36 of the power cord connection portion 32 may be provided in two rows, with a plurality arranged in each row. In this case, each wire 27c of the power cord 27 is inserted into the wire insertion holes 36 in one row, and each wire of the feed wiring wire for sending power to another lighting device 10 is inserted into the wire insertion holes 36 in the other row. Also, as the wire connection terminal, a locking terminal for preventing the inserted power cord 27 from coming off may be used. In this case, a release button for releasing the prevention of the power cord 27 from coming off is provided on the terminal block case 34.

[0018] On the terminal block side energizing portion 33 on the lower surface side of the terminal block case 34, a plurality of slit-shaped connection grooves 37 extending from the lower surface of the terminal block case 34 to one side surface are provided side by side in the width direction of the terminal block case 34 (the width direction corresponding to the short side direction of the appliance body 11 when the terminal block 29 is attached to the appliance body 11). The connection grooves 37 are provided in a slit shape that is long in the direction along the longitudinal direction of the appliance body 11 and narrow in the direction along the short side direction of the appliance body 11 when the terminal block 29 is attached to the appliance body 11. Inside each connection groove 37, blade receiving terminals 35 (see FIG. 7), which are main body side terminals, are respectively arranged. Each blade receiving terminal 35 is electrically connected to each wire connection terminal arranged in each wire insertion hole 36.

[0019] The terminal block 29 is attached to the appliance body 11 at a position directly below the wiring hole 28 in a state where the power line connection portion 32 on the upper surface side faces the wiring hole 28. For attaching the terminal block 29, for example, a structure using a push-in type fixture that fixes by pushing a key-shaped fixing portion into the terminal block mounting holes provided around the wiring hole 28 of the appliance body 11, a claw fixing structure that fixes by pushing a claw protruding from the terminal block case 34 into the terminal block mounting holes of the appliance body 11, a claw fixing structure that fixes by pushing the terminal block case 34 onto the claws protruding from the appliance body 11, etc. are used. That is, the terminal block 29 has a push-in mounting structure that is mounted by pushing the terminal block 29 into the appliance body 11 from a direction perpendicular to the top plate portion 20 of the appliance body 11 (the axial direction of the wiring hole 28). Note that the terminal block 29 may be attached to the appliance body 11 with screws.

[0020] When the terminal block 29 is attached to the appliance body 11, the open end of the wire insertion hole 36 faces the wiring hole 28, and the axial direction of the wire insertion hole 36 is arranged along the axial direction of the wiring hole 28. Therefore, the power line 27 with the wire 27c inserted into the wire insertion hole 36 vertically penetrates the wiring hole 28 of the appliance body 11.

[0021] The terminal block 29 is combined with an insulating member 39 that covers at least the power line connection portion 32. The insulating member 39 is, for example, in the form of a sheet or a cap, covers the power line connection portion 32, is attached to the terminal block 29, and covers the unused wire insertion holes 36 of the terminal block 29. The wire 27c of the power line 27 connected to the terminal block 29 passes through the insulating member 39. Note that the insulating member 39 may be attached to the appliance main body 11 so as to cover the wiring hole 28, thereby covering the power line connection portion 32 of the terminal block 29 facing the wiring hole 28.

[0022] The spring receiving member 30 is shown in FIGS. 2 and 3. The spring receiving member 30 is attached at two locations near both ends in the longitudinal direction on the lower surface of the top plate portion 20 of the appliance main body 11. The spring receiving member 30 is attached substantially perpendicular to the lower surface of the top plate portion 20, a hook hole 41 is provided inside the spring receiving member 30, and a hook protrusion 42 protrudes upward from the center of the lower edge of this hook hole 41.

[0023] Next, the light source unit 12 is shown in FIGS. 1, 2, 4 to 8. The light source unit 12 includes a long chassis 50, a light source module 51 (see FIG. 7) which is a light source attached to the lower surface side of this chassis 50, a light source cover 52 which covers this light source module 51 and is attached to the chassis 50, and a pair of mounting springs 53 which are light source unit side mounting portions disposed on the upper surface side of the chassis 50. A power supply unit 54 for supplying lighting power to the light source module 51 is attached to the light source unit 12, and the light source unit 12 includes the power supply unit 54.

[0024] The chassis 50 is made of metal and is provided in a long shape. The chassis 50 has a long light source mounting portion 56 and side wall portions 57 that are raised from both side portions in the short hand direction of this light source mounting portion 56 to the back side.

[0025] In addition, the light source module 51 includes a long light source substrate 59 and a plurality of light emitting elements 60 mounted longitudinally on the front side of the light source substrate 59. The light source substrate 59 is attached to the chassis 50 such that the back side faces the lower surface side of the chassis 50. As the light emitting elements 60, semiconductor light emitting elements such as LEDs or organic ELs are used, for example. The light source module 51 is electrically connected to the lighting power output section of the power supply section 54 by a lighting power supply line.

[0026] Also, the light source cover 52 is made of a resin having translucency and light diffusing properties, and light from the light emitting elements 60 passes through it. The light source cover 52 is provided in a long shape and is formed such that the cross-sectional shape in the width direction with respect to the longitudinal direction is a convex curved surface on the front side. The light source cover 52 is slid from the longitudinal direction with respect to the chassis 50 and integrally combined.

[0027] On the upper surface side of the light source cover 52, an opening for arranging the light source module 51 is formed along the longitudinal direction in the central region in the width direction, and contact portions 62 that can contact the lower ends of the side plate portions 21 on both sides of the instrument body 11 are formed along the longitudinal direction in both side regions of the opening, which are both side regions in the width direction.

[0028] An end face cover 63 is attached to the end of the light source cover 52. The end face cover 63 is made of resin and may be non-translucent or may have translucency. The end face cover 63 is attached to the end of the light source cover 52 combined with the chassis 50 and holds the light source cover 52 on the chassis 50.

[0029] Further, the mounting spring 53 is attached to the upper surface of the chassis 50 at two locations near both longitudinal ends by the attachment members 65. The mounting spring 53 is constituted by, for example, a torsion spring, a pair of coil portions 66 are held by the attachment members 65, and a substantially U-shaped hook portion 67 connecting between one end portions of the pair of coil portions 66 extends toward each end side in the longitudinal direction of the light source unit 12, and this hook portion 67 can be engaged with the hook hole 41 of the spring receiving member 30. The other end portions of the pair of coil portions 66 are attached to the attachment members 65. The mounting spring 53 is arranged such that a spring force acts in a direction in which the hook portion 67 goes from the upper side to the lower side through the end side of the chassis 50. The mounting spring 53 inserts the hook portion 67 into the hook hole 41 of the spring receiving member 30 of the instrument main body 11 in a state where the hook portion 67 is pulled up from the chassis 50 against the spring force and hooks it on the hook projection 42, thereby temporarily suspending the light source unit 12 on the instrument main body 11. Further, by pushing up the light source unit 12, the light source unit 12 is pulled up until the contact portion 62 of the light source cover 52 contacts the lower end portion of the side plate portion 21 of the instrument main body 11 by the spring force of the mounting spring 53 and is attached to the instrument main body 11, and is configured to hold the attached state.

[0030] Note that the mounting spring 53 is not limited to a torsion spring, and a leaf spring or the like may be used. Further, the mounting spring 53 may be attached to the instrument main body 11 and the spring receiving member 30 may be attached to the light source unit 12.

[0031] Further, the power supply unit 54 is long and is attached to the upper surface of the chassis 50 along the longitudinal direction, and is housed in the housing portion 25 of the instrument main body 11 when the light source unit 12 is attached to the instrument main body 11. One part of one end side in the longitudinal direction of the power supply unit 54 is attached to the upper surface of the chassis 50 at a position facing the wiring hole 28 of the instrument main body 11 and the terminal block 29 attached at the position of the wiring hole 28. The power supply unit 54 inputs AC power through the terminal block 29, converts it into lighting power which is a predetermined DC power, and supplies it to the light source module 51. The lighting power output portion of the power supply unit 54 and the light source module 51 are electrically connected by a lighting power supply line.

[0032] The power supply unit 54 includes a power supply board 69 on which a plurality of electronic components constituting a power supply circuit are mounted, and a power supply case 70 that houses the power supply board 69.

[0033] The power supply board 69 is provided in a long shape. On one end side in the longitudinal direction, electronic components with a low height from the power supply board 69, mainly chip components, are mounted, and a light source side energization part 71 that is electrically connected to the terminal block side energization part 33 of the terminal block 29 is provided. Also, on the other end side in the longitudinal direction, large electronic components such as transformers and electrolytic capacitors, and electronic components with a high height from the power supply board 69 are mounted.

[0034] The light source side energization part 71 is provided on the upper surface of the power supply board 69. The light source side energization part 71 is arranged at a position facing the terminal block 29 of the appliance body 11 to which the light source unit 12 is attached.

[0035] The light source side energization part 71 has an energization part case 72 and terminal blades 73 which are a plurality of light source side terminals provided on the energization part case 72.

[0036] The energization part case 72 is made of resin with insulation properties and is formed in a substantially rectangular frame shape with a central opening in the vertical direction. In the center of the energization part case 72, a substantially rectangular opening 74 through which the terminal block 29 is inserted and removed in the vertical direction is provided. The opening 74 may be opened on the upper and lower surfaces of the energization part case 72, or a bottom surface part for closing the bottom surface side of the opening 74 may be provided on the energization part case 72.

[0037] The plurality of terminal blades 73 project into the opening 74 from the wall part of the energization part case 72 located on one side in the longitudinal direction of the light source unit 12. The terminal blades 73 are in a flat plate shape, with the plate thickness surface facing the vertical direction, the terminal surface with the largest area is arranged along the vertical direction and the longitudinal direction of the light source unit 12, and while the plate thickness direction is oriented in the width direction of the light source unit 12, a plurality of them are arranged in parallel along the width direction of the light source unit 12.

[0038] When the terminal block side energizing part 33 of the terminal block 29 relatively enters the opening 74 of the light source side energizing part 71, each terminal blade 73 is relatively inserted into each connection groove 37 of the terminal block 29, and each blade receiving terminal 35 arranged in each connection groove 37 comes into contact with the terminal blade 73 and is electrically connected. The plurality of terminal blades 73 are electrically connected to the power input part of the power circuit of the power supply board 69.

[0039] The width of the opening 74 of the light source side energizing part 71 in the longitudinal direction of the light source unit 12 is larger than the width of the terminal block 29 in the same direction. Even if the light source unit 12 is slightly displaced in the longitudinal direction when attaching and detaching the light source unit 12 to and from the appliance body 11, the terminal block side energizing part 33 of the terminal block 29 can relatively enter the opening 74 of the light source side energizing part 71. Also, regarding the connection grooves 37 of the terminal block 29, the blade receiving terminals 35, and the terminal blades 73, even if the light source unit 12 is slightly displaced in the longitudinal direction when attaching and detaching the light source unit 12 to and from the appliance body 11, and even if there is a variation in the vertical position where the terminal block 29 enters the opening 74 of the light source side energizing part 71, each terminal blade 73 is relatively inserted into each connection groove 37 of the terminal block 29, and each blade receiving terminal 35 arranged in each connection groove 37 comes into contact with the terminal blade 73 and is electrically connected. They are provided with a large allowance in the longitudinal direction and the vertical direction of the light source unit 12.

[0040] The power supply case 70 includes a bottom plate 75 arranged on the upper surface of the chassis 50 and attached by screwing or the like, and covers 76, 77, 78 that cover the upper side and both sides in the width direction of the power supply board 69 accommodated between the bottom plate 75 and the bottom plate 75.

[0041] Next, the construction of the lighting device 10 will be described.

[0042] Pull the power line 27 drawn from the ceiling surface into the appliance body 11 through the wiring hole 28, screw nuts through the pair of mounting holes 26 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.

[0043] Below the appliance body 11, each electric wire 27c of the power cord 27 is inserted into each wire insertion hole 36 of the power cord connection part 32 of the terminal block 29 and electrically connected. After the connection, while pushing back the power cord 27 from the wiring hole 28 toward the ceiling surface side, the terminal block 29 is pushed into a position facing the wiring hole 28 of the appliance body 11 and attached. To push and attach the terminal block 29 to the appliance body 11, the above-described push-in type fixture, claw fixing structure, etc. are used.

[0044] At this time, since it is possible to connect the power cord 27 to the terminal block 29 and attach the terminal block 29 to the appliance body 11 without bending the power cord 27 drawn into the appliance body 11 from the wiring hole 28, there is no need for the operation of bending the power cord 27, and it is easy to push back the power cord 27 in a substantially straight state from the wiring hole 28 toward the ceiling surface side when attaching the terminal block 29 to the appliance body 11, and the work is easy.

[0045] As shown in FIG. 7, in a state where the terminal block 29 is attached to the appliance body 11, the power cord connection part 32 of the terminal block 29 faces upward and faces the wiring hole 28, and the power cord 27 connected to the power cord connection part 32 passes straight through the wiring hole 28. Further, when using a push-in type fixture or the like, the terminal block 29 is attached in a state where it can move in a direction parallel to the lower surface of the top plate part 20 of the appliance body 11, that is, in the longitudinal direction and the lateral direction of the appliance body 11.

[0046] The upward power cord connection part 32 of the terminal block 29 is covered with an insulating member 39, and the intrusion of dust etc. into the wire insertion hole 36 of the power cord connection part 32 is reduced.

[0047] Subsequently, the hooking parts 67 of the pair of mounting springs 53 are raised from the light source unit 12, and the tip sides of these respective hooking parts 67 are inserted into the hooking holes 41 of the pair of spring receiving members 30 of the appliance body 11 and hooked on the hooking protrusions 42. In this state, the light source unit 12 is in a state of being temporarily suspended below the appliance body 11.

[0048] By pushing the light source unit 12 upward toward the fixture body 11, the engaging portion 67 of the mounting spring 53 is inserted into the engaging hole 41 of the spring receiving member 30, and a spring force for pulling up the light source unit 12 to the fixture body 11 acts on the mounting spring 53, and the light source unit 12 is pulled up and attached to the fixture body 11.

[0049] At this time, as shown in FIG. 7, the lower terminal block side energizing portion 33 of the terminal block 29 relatively enters the opening 74 of the light source side energizing portion 71, and each terminal blade 73 of the light source side energizing portion 71 is relatively inserted into each connection groove 37 of the terminal block 29, and each terminal blade 73 contacts each blade receiving terminal 35 in each connection groove 37 and is electrically connected.

[0050] Since the blade receiving terminal 35 of the terminal block 29 and the terminal blade 73 of the light source side energizing portion 71 can be connected even if there is a slight deviation in the longitudinal position of the fixture body 11 and the light source unit 12, even if the light source unit 12 is slightly displaced in the longitudinal direction when the light source unit 12 is pulled up to the fixture body 11, the terminal block side energizing portion 33 of the terminal block 29 and the light source side energizing portion 71 are electrically connected.

[0051] And the AC power supplied by the power line 27 is input to the power supply unit 54 through the terminal block 29 and the light source side energizing portion 71, and the lighting power obtained by converting the AC power by the power supply unit 54 is supplied to the light source module 51, and the plurality of light emitting elements 60 of the light source module 51 are lit.

[0052] Also, when removing the light source unit 12 from the fixture body 11, the light source unit 12 is pulled down against the spring force of the mounting spring 53, and the mounting spring 53 is removed from the spring receiving member 30, whereby the light source unit 12 is removed. When the light source unit 12 is pulled down, it is detached from the terminal block 29 of the fixture body 11 from the light source side energizing portion 71, and the electrical connection is released.

[0053] In the lighting device 10 configured as described above, since the terminal block 29 is attached to the appliance body 11 with the power line connection portion 32 of the terminal block 29 facing the wiring hole 28, it is not necessary to bend the strong and difficult-to-bend power line 27 to connect it to the terminal block 29, and the workability can be improved.

[0054] Furthermore, by attaching the light source unit 12 to the appliance body 11, the terminal block side energization portion 33 of the terminal block 29 and the light source side energization portion 71 of the light source unit 12 are electrically connected, so that wiring work between the appliance body 11 and the light source unit 12 is not required, and the workability can be improved.

[0055] Also, since the power line connection portion 32 of the terminal block 29 is covered with the insulating member 39, it is possible to reduce the intrusion of dust or the like into the upward-facing power line connection portion 32.

[0056] Note that the terminal block 29 may be attached to the appliance body 11, and during construction, the power line 27 drawn from the ceiling surface may be connected to the power line connection portion 32 of the terminal block 29 through the wiring hole 28 of the appliance body 11, and the appliance body 11 may be installed on the ceiling surface.

[0057] The wiring hole 28 of the appliance body 11 is not limited to the center in the longitudinal direction of the appliance body 11, and may be on the end side. The light source side energization portion 71 of the light source unit 12 may be arranged corresponding to the position of the wiring hole 28 of the appliance body 11, that is, the position of the terminal block 29 arranged to face the wiring hole 28. If there is a wiring hole 28 in the center in the longitudinal direction of the appliance body 11, it is easy to perform the connection work between the power line 27 and the terminal block 29.

[0058] The light source side energization portion 71 may be provided separately from the power supply portion 54, and can be arranged at a position corresponding to the wiring hole 28 and the terminal block 29 of the appliance body 11 regardless of the position of the power supply portion 54 in the light source unit 12.

[0059] In addition, a movable connection structure that is movably attached to at least the longitudinal direction (preferably, all horizontal directions including the longitudinal direction and the lateral direction) of the lighting device 10 may be used for the terminal block 29 and the light source side energizing portion 71, so as to absorb the positional deviation when the light source unit 12 is attached to the appliance main body 11 and make an electrical connection.

[0060] Although several embodiments of the present invention have been described, these embodiments are presented by way of example 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.
