[0008] One embodiment will be described below with reference to the drawings.
[0009] Figures 1 to 3 show the lighting device 10. The lighting device 10 comprises a long fixture body 11 installed on the ceiling surface which is the installation area, a long light source unit 12 that is detachably attached to one end in the longitudinal direction on the underside of the fixture body 11, and an accessory unit 13 that is attached to the other end in the longitudinal direction on the underside of the fixture body 11.
[0010] The fixture body 11 is made of metal and is elongated. The fixture body 11 comprises a top plate portion 20, side plate portions 21 on both sides that are bent downward from both sides in the short direction intersecting the longitudinal direction of the top plate portion 20, reflector portions 22 on both sides that protrude diagonally upward from the lower ends of these side plate portions 21, and end plate portions 23 that close both ends in the longitudinal direction, forming 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 on both ends, and a recess 25 is formed inside that opens toward the opening 24. Note that the fixture body 11 is not limited to the inverted Fuji shape, and may also be a trough type without reflector portions 22, or a capped type with caps that protrude diagonally downward from the lower ends of the side plate portions 21 on both sides.
[0011] Mounting holes 26 (see Figure 5) are provided near both ends of the top plate 20 in the longitudinal direction for attaching to two suspension bolts protruding from the ceiling structure. A wiring hole 27 (see Figure 3) is provided in the center of the top plate 20 in the longitudinal direction for bringing power lines drawn from the ceiling surface into the fixture body 11.
[0012] As shown in Figure 5, in the area of the main body 11 of the fixture to which the accessory unit 13 is attached, the top plate portion 20 is provided with an operating hole 20a through which the second screw 69, which will be described later, can pass.
[0013] As shown in Figures 1 to 5, knockout sections 28 are provided at both end plate sections 23. The knockout sections 28 are opened when multiple lighting devices 10 are installed in a series along the longitudinal direction and are used to pass through wiring for supplying power from one lighting device 10 to an adjacent lighting device 10. The knockout section 28 is provided with a knockout plate 30 via a connecting section 29 that allows it to be detached from the end plate section 23, and a knockout hole 31 is opened by punching out the knockout plate 30 from the end plate section 23 so as to detach the connecting section 29. In other words, the knockout hole 31 provided in the connecting section 29 is closed by the knockout plate 30, and the knockout hole 31 is opened when the knockout plate 30 is punched out.
[0014] The knockout portion 28 is formed in an elongated shape with an arc shape at its lower end. The knockout portion 28 has a pair of parallel separation grooves 32 that are provided parallel to each other at a predetermined width from the upper end of the end plate portion 23 downwards, and an arc-shaped separation groove 33 is provided to connect the lower ends of the pair of parallel separation grooves 32 in an arc shape. A connecting portion 29 is provided in the middle of the pair of parallel separation grooves 32 to connect the end plate portion 23 and the knockout plate 30.
[0015] Furthermore, as shown in Figures 2 and 3, a terminal block 36 is attached to the underside of the top plate portion 20 of the fixture body 11 on one end in the longitudinal direction of the fixture body 11 relative to the wiring hole 27, a power supply unit 37 is attached to the other end in the longitudinal direction of the fixture body 11 relative to the wiring hole 27, and a plurality of bases 38 are attached to the fixture body 11 corresponding to the mounting positions of the light source unit 12 and the accessory unit 13.
[0016] The terminal block 36 is connected to a power line that supplies AC power, for example, from a commercial AC power source, which is drawn into the fixture body 11. The terminal block 36 and the power supply unit 37 are electrically connected by an internal power line that is wired inside the fixture body 11, and the AC power input by the power line is supplied to the power supply unit 37. The power line connected to the terminal block 36 may be drawn out from the ceiling surface and brought in through the wiring hole 27, or it may be brought in from another lighting device 10 through the knockout hole 31 of the knockout section 28.
[0017] The power supply unit 37 receives AC power through the terminal block 36, converts it into a predetermined DC power called lighting power, and supplies it to the light source unit 12. Output lines are drawn from the power supply unit 37 that are electrically connected to the light source unit 12 and output lighting power.
[0018] The pedestal 38 is commonly used for both attaching the light source unit 12 to the instrument body 11 with an attachment member (spring socket) 39 which is a first component A, and attaching the accessory unit 13 which is a second component B. A pair of pedestals 38 are arranged in the area for attaching the light source unit 12 of the instrument body 11, and a pair of pedestals 38 are arranged in the area for attaching the accessory unit 13 of the instrument body 11.
[0019] As shown in FIGS. 5 and 6, the attachment member 39 is attached by the pedestals 38 at two locations near both ends in the longitudinal direction of the instrument body 11 in the area for attaching the light source unit 12 to the instrument body 11. The attachment member 39 is made of metal (sheet metal), and includes a fixing portion 40 attached to the pedestal 38, a spring receiving portion 41 bent substantially at a right angle from this fixing portion 40, a hanging hole 42 provided in the inner area of this spring receiving portion 41, and a hanging projection 43 protruding upward from the center of the lower edge of this hanging hole 42.
[0020] At the bending location between the fixing portion 40 and the spring receiving portion 41, a pair of reinforcing ribs 44 are provided to reinforce and maintain the postures of the fixing portion 40 and the spring receiving portion 41. The pair of reinforcing ribs 44 are provided at positions equidistant from the center in the width direction w (corresponding to the lateral direction of the instrument body 11) of the attachment member 39.
[0021] In the fixing portion 40, a notch 45 is provided at the center in the width direction w of the side opposite to the side where the spring receiving portion 41 is bent. This notch 45 is provided to avoid interference with the suspension bolt, nut, and the tool for operating the nut when nutting the suspension bolt using the mounting hole 26 of the instrument body 11. In the fixing portion 40, a pair of first screws 46 are provided with a pair of screwing holes 47 screwed through the pedestal 38. The pair of screwing holes 47 are arranged side by side in the width direction w, but are offset to one side in the width direction w to have a predetermined distance from the pair of reinforcing ribs 44.
[0022] Figures 1 to 3 also show the light source unit 12. The light source unit 12 comprises a long chassis 50, a light source module 51 which is a light source attached to the lower side of the chassis 50, a cover 52 which covers the light source module 51 and is attached to the chassis 50, and a pair of mounting springs 53 which are arranged on the upper side of the chassis 50.
[0023] The light source module 51 has a long light source substrate and multiple light-emitting elements mounted along the longitudinal direction on the front side of the light source substrate. The rear side of the light source substrate is attached to the underside of the chassis 50. Semiconductor light-emitting elements such as LEDs and organic ELs are used as light-emitting elements. An input line is drawn out from the light source module 51 to the upper side of the chassis 50, and when the lighting device 10 is installed, the input line is electrically connected to the output line from the power supply unit 37, thereby supplying lighting power from the power supply unit 37 to the light source module 51.
[0024] The cover 52 is made of a light-transmitting and light-diffusing resin, and its cross-sectional shape in the short direction intersecting the long direction is formed in a convex arc shape, allowing light from the light-emitting element of the light source module 51 to pass through.
[0025] The mounting spring 53 is attached to the upper surface of the chassis 50 at two locations near both ends in the longitudinal direction by spring mounting members 54. The mounting spring 53 is, for example, a torsion spring, with a pair of coil sections 55 held by the spring mounting members 54, and a roughly U-shaped hook section 56 connecting one end of the pair of coil sections 55 extending toward each end in the longitudinal direction of the light source unit 12, so that this hook section 56 can engage with the hook holes 42 of the mounting member 39. The other ends of the pair of coil sections 55 are positioned on the spring mounting members 54. The mounting spring 53 is arranged such that the spring force acts on the hook section 56 in a direction from the upper side of the chassis 50 through the end side toward the lower side. The mounting spring 53 is inserted into the hooking hole 42 of the mounting member 39 of the fixture body 11 with the hooking portion 56 pulled up against the spring force from the chassis 50 and hooked onto the hooking projection 43, thereby temporarily suspending the light source unit 12 from the fixture body 11. Furthermore, by pushing up the light source unit 12, the spring force of the mounting spring 53 pulls up the light source unit 12 and attaches it to the fixture body 11.
[0026] Note that the mounting spring 53 is not limited to a torsion spring; a leaf spring or the like may also be used. Alternatively, the mounting spring 53 may be attached as the first component A to the base 38 of the fixture body 11, and the mounting member 39 may be placed on the light source unit 12.
[0027] Furthermore, Figures 1 to 3, 5, and 7 show the accessory unit 13. The accessory unit 13 is, for example, a human presence sensor unit that detects a human body. The accessory unit 13 comprises a housing 60 and an accessory unit body 61 located within the housing 60.
[0028] The housing 60 has an insertion portion 62 that is inserted into the recess 25 of the fixture body 11, and a protruding portion 63 that is positioned on the outside of the fixture body 11 below the insertion portion 62. The cross-sectional shape of the protruding portion 63 in the short direction is formed in a convex arc shape, corresponding to the shape of the cover 52 of the light source unit 12.
[0029] On both sides of the housing 60 in the short direction, recessed groove-shaped engaging portions 64 are formed between the insertion portion 62 and the protruding portion 63, which engage with the lower end of the side plate portion 21 of the device body 11.
[0030] A locking portion 65 and a screw hole 66 are provided on one longitudinal end of the housing 60 and on one short side of the insertion portion 62. The locking portion 65 has a roughly L-shaped cross-section, with a rising portion 67 projecting upward and a bent portion 68 projecting outward from the upper end of the rising portion 67 toward the outside of one short side of the housing 60. A second screw 69 is screwed into the screw hole 66 through the base 38. On the other longitudinal end of the housing 60, a boss portion 70 is erected on the other short side of the insertion portion 62, and a screw hole 71 is provided at the upper end of this boss portion 70. A second screw 69 is screwed into the screw hole 71 through the base 38. The screw holes 66 and 71 are positioned approximately coaxially with the operating hole 20a of the top plate portion 20 of the device body 11 by placing the accessory unit 13 on the device body 11 via the base 38.
[0031] The attached unit body 61 includes a sensor unit 72 positioned on the surface side of the protruding portion 63 of the housing 60, and a sensor circuit unit 73 and a sensor power supply unit 74 positioned on the insertion portion 62 side of the housing 60. The sensor unit 72 includes a sensor element and a lens that focuses heat rays generated by the human body onto the sensor element. The sensor circuit unit 73 drives the sensor element of the sensor unit 72 and outputs a detection signal to the power supply unit 37 depending on whether or not the sensor unit 72 detects a human body. The sensor circuit unit 73 and the power supply unit 37 are electrically connected by a signal line. The sensor power supply unit 74 is electrically connected to the terminal block 36 by an internal power line wired inside the device body 11, and converts the supplied AC power into a predetermined operating power and supplies it to the sensor circuit unit 73.
[0032] The attached unit 13 may be any of the following: a camera unit for photographing the illuminated space, an emergency light unit that lights up during a power outage, etc.
[0033] Figures 2 to 7 also show the base 38. The base 38 is made of metal (sheet metal) and has a flat, roughly rectangular base portion 80 and legs 81 that are bent from both sides of the width direction w, which is the longitudinal direction of the base portion 80. The base 38 has the width direction w of the base portion 80 facing the short direction of the main body of the appliance 11 and the legs 81 are attached to the underside of the top plate portion 20.
[0034] The base portion 80 has a notch 82 in the center of one side in the width direction w, and is provided in a shape substantially identical to the outer shape of the fixing portion 40 of the mounting member 39. Therefore, the notch 82 of the base portion 80, like the notch 45 of the mounting member 39, has the function of avoiding interference with the suspension bolt, nut, and tool used to operate the nut when fastening the suspension bolt with a nut using the mounting hole 26 of the fixture body 11.
[0035] The base portion 80 has a plurality of first mounting holes 83 for attaching the mounting member 39, which is the first component A, and a plurality of second mounting holes 84 for attaching the accessory unit 13, which is the second component B.
[0036] The first mounting holes 83 are a pair of circular holes provided in correspondence with the positions of the pair of screw holes 47 of the mounting member 39, through which a pair of first screws 46 for attaching the mounting member 39 to the base 38 are inserted. The pair of first mounting holes 83 correspond to the positions of the pair of screw holes 47 of the mounting member 39, are arranged parallel to the width direction w of the base portion 80, and are positioned offset to one side of the width direction w of the base portion 80.
[0037] The second mounting hole 84 has circular holes 85 and 86, and an irregularly shaped hole 87 that has a different shape from the circular holes 85 and 86. One circular hole 85 and the irregularly shaped hole 87 are located on one side of the base portion 80 in the width direction w (the side to which the first mounting hole 83 is offset), and the other circular hole 86 is located on the other side. The irregularly shaped hole 87 on one side of the base portion 80 in the width direction w and the circular hole 86 on the other side are located further out in the width direction w than the first mounting hole 83. The circular hole 85 located on one side of the base portion 80 in the width direction w is located at approximately the same position as the first mounting hole 83 on one side, and is shifted toward the notch portion 82 side relative to the first mounting hole 83, but may also be located further out in the width direction w than the first mounting hole 83.
[0038] The irregularly shaped hole 87 has a through-hole portion 88 with a wide width in the width direction w, and a mounting hole portion 89 with a narrower width in the width direction w than the through-hole portion 88, and is formed in a roughly L-shape when viewed from a direction perpendicular to the surface of the base portion 80. The through-hole portion 88 and the mounting hole portion 89 of the irregularly shaped hole 87 are aligned in a direction that intersects with the width direction w and is parallel to the leg portion 81, with the through-hole portion 88 located on the opposite side of the notch portion 82 of the base portion 80, and the mounting hole portion 89 located on the notch portion 82 side. The through-hole portion 88 of the irregularly shaped hole 87 and the first mounting hole 84 and the other circular hole 86 are aligned in the width direction w, and the mounting hole portion 89 and one of the circular holes 85 are aligned in the width direction w. The shape of the irregularly shaped hole 87 may also be a daruma hole shape having a large diameter hole and an elongated hole.
[0039] At the tips of the pair of legs 81, a leg mounting portion 90 is bent so as to face the back side of the base portion 80. The leg mounting portion 90 is provided with fixture mounting holes 92 which are attached to the top plate portion 20 of the fixture body 11 with base mounting screws 91. At least a portion of the pair of fixture mounting holes 92 of the pair of legs 81 is positioned outward in the width direction w than the first mounting hole 83 and the second mounting hole 84 of the base portion 80.
[0040] As shown in Figures 3 to 5, when the base 38 is attached to the fixture body 11, a wiring space 96 is formed between the top plate portion 20 of the fixture body 11 and the base portion 80 and pair of legs 81 of the base 38, allowing the electric wire 95 (see Figure 3) to pass through.
[0041] The dimension L1 between the top plate portion 20 of the fixture body 11 and the base portion 80 of the base 38, which form the wiring space 96, is greater than the dimension L2 from the top plate portion 20 to the furthest point from the top plate portion 20 in the area of the maximum width of the knockout portion 28. The furthest point from the top plate portion 20 in the area of the maximum width of the knockout portion 28 is between the parallel separation groove 32 and the arc-shaped separation groove 33, and corresponds to the lower limit of the effective area through which the electric wire 95 can pass. Furthermore, the dimension L1 between the top plate portion 20 of the fixture body 11 and the base portion 80 of the base 38, which form the wiring space 96, is greater than the dimension L3 from the top plate portion 20 to the height where the electric wire 95 of the terminal block 36 is connected (the height of the lower surface of the connection end of the electric wire 95 connected to the terminal block 36).
[0042] Then, as shown in Figures 5 and 6, the mounting member 39 is attached to the fixture body 11 after being fixed in combination with the base 38. The base portion 80 of the base 38 and the fixing portion 40 of the mounting member 39 are combined, and a pair of first screws 46 are screwed through a pair of first mounting holes 83 in the base portion 80 into a pair of screw holes 47 in the fixing portion 40 and tightened to attach the base 38 and the mounting member 39.
[0043] The base 38, combined with the mounting member 39, is inserted into the fixture body 11, the leg mounting portions 90 of the pair of legs 81 are positioned on the underside of the top plate 20, and the pair of base mounting screws 91 are screwed through the top plate 20 of the fixture body 11 into the fixture mounting holes 92 of the leg mounting portions 90 of the base 38 and tightened to attach the base 38 to the fixture body 11.
[0044] Furthermore, as shown in Figures 5 and 7, the accessory unit 13 can be attached in two ways: a first mounting procedure in which the accessory unit 13 is attached to the pair of bases 38 after the pair of bases 38 have been attached to the fixture body 11, and a second mounting procedure in which the accessory unit 13 is attached to the fixture body 11 after being fixed in combination with the pair of bases 38.
[0045] In the first installation procedure, the pair of bases 38 for mounting the accessory unit 13 are attached to the fixture body 11 as described above. The pair of bases 38 are positioned so that the notches 82 face the end opposite to the longitudinal center of the fixture body 11. The circular hole 85 of one base 38, which is positioned towards the longitudinal center of the fixture body 11, and the circular hole 86 of the other base 38, which is positioned towards the end away from the longitudinal center of the fixture body 11, are positioned approximately coaxially with and opposite the operating hole 20a of the top plate portion 20 of the fixture body 11.
[0046] Insert the insertion portion 62 of the housing 60 of the attached unit 13 into the main body of the device 11, engage the engaging portion 64 of the housing 60 with the side plate portion 21 of the main body of the device 11, insert the locking portion 65 into the insertion hole portion 88 of the irregularly shaped hole 87 of the base 38, move the housing 60 towards the end along the longitudinal direction of the main body of the device 11, move the locking portion 65 to the mounting hole portion 89 and hook the bent portion 68 of the locking portion 65 onto the upper surface of the base portion 80. One second screw 69 is screwed through the operating hole 20a of the top plate portion 20 of the main body of the device 11 into the screw hole 66 of the attachment unit 13 from the circular hole 85 of the base portion 80 of one base 38 and tightened, and the other second screw 69 is screwed through the circular hole 86 of the base portion 80 of the other base 38 into the screw hole 66 of the attachment unit 13 and tightened, thereby attaching the attachment unit 13 to the main body of the device 11 via the base 38.
[0047] At this time, since the locking portion 65 is offset to one side in the shorter direction of the housing 60, the locking portion 65 can be easily attached to the base 38 by engaging the engaging portion 64 on one side of the housing 60 with the side plate portion 21 on one side of the fixture body 11 and inserting the locking portion 65 into the irregularly shaped hole 87 of the base 38. Furthermore, since the housing 60 can be fixed with the second screw 69 to the second mounting hole 84 (circular hole 85) located close to the irregularly shaped hole 87, it is possible to reliably prevent the locking portion 65 from coming out of the irregularly shaped hole 87.
[0048] In the second installation procedure, the base 38 and the attached unit 13 are combined via the locking portion 65 as described above and attached using the second screw 69, and then the base 38 is attached to the fixture body 11 using the base mounting screw 91 as described above.
[0049] Thus, the base 38 can be used in common for both the mounting member 39, which is the first component A for attaching the light source unit 12 to the fixture body 11, and the attachment unit 13, which is the second component B. Therefore, it is not necessary to provide separate dedicated parts for each type of component, and component costs can be reduced.
[0050] The base portion 80 of the base 38 is provided with a first mounting hole 83 for mounting the mounting member 39 and a second mounting hole 84 including an irregularly shaped hole 87 for mounting the accessory unit 13. However, since the second mounting hole 84 is provided further outward in the width direction w than the first mounting hole 83, the irregularly shaped hole 87 is positioned on one side of the base portion 80 in the width direction w. This allows the accessory unit 13, which is attached to the irregularly shaped hole 87, to be easily attached by engaging one side in the short direction (width direction w) with one side of the fixture body 11, thereby improving ease of installation.
[0051] The base 38 has mounting holes 92 provided on the legs 81 on both sides in the width direction w of the base portion 80, which are located further out in the width direction w than the first mounting holes 83 and second mounting holes 84 of the base portion 80, thereby improving the strength when attached to the fixture body 11.
[0052] Furthermore, when multiple lighting devices 10 are installed in a series along the longitudinal direction, wiring is used to supply power from one lighting device 10 to an adjacent lighting device 10. In this case, the knockout plate 30 of the knockout portion 28 provided on the end plate portion 23 of the fixture body 11 is punched out and separated to open a knockout hole 31, and the electric wire 95, which is the wiring between the fixtures, is passed through this knockout hole 31.
[0053] The electric wire 95, which is drawn into the fixture body 11 through the knockout hole 31, is connected to the terminal block 36 by passing through the wiring space 96 above the base portion 80 of the base 38.
[0054] If the electric wire 95 is connected to the terminal block 36 without passing it through the wiring space 96 above the base portion 80 of the base 38, the electric wire 95 will hang down under its own weight between the knockout portion 28 of the fixture body 11 and the terminal block 36, and there is a risk that the electric wire 95 will be pinched when attaching the light source unit 12 to the fixture body 11. In addition, since the electric wire 95 will have to be rerouted, the amount of electric wire 95 used will increase.
[0055] By connecting the electric wire 95 to the terminal block 36 through the wiring space 96 above the base portion 80 of the base 38, the sagging of the electric wire 95 is reduced, and the risk of the electric wire 95 being pinched when attaching the light source unit 12 to the fixture body 11 is also reduced. Moreover, since the electric wire 95 can be connected over the shortest distance, the amount of electric wire 95 used can be reduced.
[0056] The dimension L1 between the top plate portion 20 of the fixture body 11 and the base portion 80 of the base 38, which form the wiring space 96, is greater than the dimension L2 from the top plate portion 20 to the furthest point from the top plate portion 20 in the area of the maximum width of the knockout portion 28. Therefore, it is easier to pass the electric wire 95 pulled in from the opened knockout hole 31 between the top plate portion 20 of the fixture body 11 and the base portion 80 of the base 38, thereby improving wiring work.
[0057] The dimension L1 between the top plate portion 20 of the fixture body 11 and the base portion 80 of the base 38, which form the wiring space 96, is greater than the height position from which the wires 95 of the terminal block 36 are connected from the top plate portion 20. Therefore, it is possible to connect the wires 95 over the shortest distance, thereby reducing the amount of wire used.
[0058] Furthermore, when attaching or detaching the light source unit 12 to the fixture body 11, the mounting spring 53 catches, and a rotational moment acts on the mounting member 39 to which the spring force acts (a counterclockwise rotational moment acts on the mounting member 39 on the left side of Figure 3). If the base 38 and the mounting member 39 were an integrated structure, a rotational moment would act on the mounting member 39 with the mounting point to the fixture body 11 as the pivot point, making the rotational moment larger and the mounting member 39 more prone to deformation. In contrast, because the base 38 and the mounting member 39 are separate structures, a rotational moment acts on the mounting member 39 with the mounting point to the base 38 as the pivot point, resulting in a smaller rotational moment and suppressing deformation of the mounting member 39.
[0059] Furthermore, the first part A and the second part B, which are attached to the fixture body 11 using the base 38, are not limited to the mounting member 39 and the accessory unit 13, but can be any part that is attached to the fixture body 11.
[0060] 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]
