DETAILED DESCRIPTION OF THE INVENTION

[0008] The first embodiment will be described below with reference to FIGS.

[0009] 1 to 3, the wiring duct (lighting duct) 10 is provided in a long rail shape and is installed on an installation surface such as a ceiling surface, and electrical equipment can be attached and electrically connected at any position in the longitudinal direction for use.

[0010] The wiring duct 10 comprises a duct body 11, a pair of insulators 12 arranged on both sides of the width direction, which is the short direction that intersects the longitudinal direction within the duct body 11, and a pair of conductors 13 attached to each of these insulators 12.

[0011] The duct body 11 is made of a metal such as aluminum, and is elongated and hollow, with a generally rectangular shape. A duct opening 11a is provided in the center of the underside of the duct body 11 along the longitudinal direction. Support edges 11b are provided on both sides of the duct opening 11a at the bottom of the duct body 11. A polarity protrusion 11c indicating the ground side polarity protrudes downward from one side of the bottom of the duct body 11.

[0012] The pair of insulators 12 are made of, for example, resin and are provided long. The pair of insulators 12 support the conductor 13 and are arranged in the duct body 11 on both sides of the duct opening 11a along the longitudinal direction.

[0013] The pair of conductors 13 are elongated, for example, made of metal plates. The pair of conductors 13 are arranged facing each other on both sides of the duct opening 11a within the duct body 11 by a pair of insulators 12. A predetermined external power such as AC power or DC power from an external power source is applied to the pair of conductors 13.

[0014] 1 to 3, reference numeral 20 denotes a lighting device. The lighting device 20 is attached to any position in the longitudinal direction of the wiring duct 10 and is electrically connected for use. The lighting device 20 is formed to be long and is a slim lighting device whose width dimension in the width direction, which is the short side direction intersecting the longitudinal direction, is smaller than its height dimension in the height direction. The lighting device 20 corresponds to forming a line light source by arranging a plurality of lighting devices 20 consecutively along the longitudinal direction of the wiring duct 10.

[0015] The lighting device 20 includes a lighting unit 21, a holding wiring duct mounting unit 22 which is an adapter for mounting one end of the lighting unit 21 to the wiring duct 10, and a power supply wiring duct mounting unit 23 which is an adapter for mounting the other end of the lighting unit 21 to the wiring duct 10.

[0016] The lighting unit 21 comprises a cover 30 which is a housing, a light source mounting portion 31 which is arranged inside the cover 30, a light source 32 which is attached to the light source mounting portion 31 and arranged inside the cover 30, and a power supply portion 33.

[0017] The cover 30 is made of resin, is long, and is formed in a box shape with a width dimension in the short direction, which is the direction intersecting the longitudinal direction, smaller than a height dimension in the height direction. The cover 30 has a front surface 35, side surfaces 36 on both sides in the short direction, and end surfaces 37 on both ends in the longitudinal direction, and an opening 38 is formed on the top surface. The cover 30 is configured by combining the front surface 35 and the side surfaces 36 on both sides, which are formed integrally, and the end surfaces 37, which are formed separately.

[0018] The lower side of cover 30, i.e., the lower sides of front surface 35, side surface 36, and end surface 37, are formed as translucent portions 39 through which light from light source 32 passes, and the upper side of cover 30, i.e., the upper sides of side surface 36 and end surface 37, are formed as opaque portions 40 through which light does not pass. In cover 30, translucent portions 39 and opaque portions 40 are integrally formed by two-color molding.

[0019] The dimension between the insides of the side portions 36 on both sides of the cover 30 is wider than the width dimension of the wiring duct mounting units 22, 23, so that the wiring duct mounting units 22, 23 can be placed inside the cover 30 through the opening 38.

[0020] On the inner surface of the side surface portions 36 on both sides of the cover 30, a light source holding portion 41 is provided at the middle position in the height direction of the side surface portions 36, below the opaque portion 40.

[0021] The light source attachment portion 31 is made of, for example, metal and is provided long. The light source attachment portion 31 is attached between the light source holding portions 41 on the side surfaces 36 on both sides of the cover 30.

[0022] The light source (light source module) 32 is attached to the lower surface side of the light source holding part 31. A substantially L-shaped support part 43 that supports one side of the light source (light source module) 32 in the width direction is provided on one side of the lower surface side of the light source holding part 31 in the width direction. A plurality of screws 44 are threadedly fastened to the other side of the lower surface side of the light source holding part 41 in the width direction to screw the other side of the light source (light source module) 32 in the width direction.

[0023] Furthermore, a light source module is used as the light source 32. The light source 32 has a long substrate 46 and a plurality of light-emitting elements 47 mounted at predetermined intervals along the longitudinal direction on the surface side of the substrate 46. The light-emitting elements 47 are LEDs, organic ELs, or the like. The back side of the substrate 46 is attached to the underside of the light source attachment portion 31 and is thermally connected thereto. Note that the light source 32 is not limited to a light source module, and may be any device that emits light, such as a lamp.

[0024] The power supply unit 33 is attached near the center in the longitudinal direction on the upper surface side of the light source attachment unit 31. The power supply unit 33 is electrically connected to the power supply wiring duct attachment unit 23 via wiring, and receives external power supplied from the wiring duct 10. The power supply unit 33 converts the input external power into lighting power such as DC power required to light the light source 32, and supplies it to the light source 32. The lighting power output unit of the power supply unit 33 and the light source 32 are electrically connected via wiring.

[0025] As shown in Figures 1 to 4, the holding wiring duct mounting unit 22 includes a housing 52 having a main body 50 and an insertion portion 51 protruding from the top surface of the main body 50, a pair of mounting members 53 arranged movably in the width direction within the housing 52 and protruding movably from both side surfaces of the insertion portion 51 in the width direction, a biasing member (not shown) that biases each mounting member 53 in the protruding direction from the insertion portion 51, and an operating member 54 arranged so as to be operable from the end side of the main body 50.

[0026] The main body 50 and the insertion portion 51 protruding from the top surface of the main body 50 are formed in a rectangular parallelepiped shape that is long and corresponds to the longitudinal direction of the wiring duct 10 and the cover 30. The width direction dimension of the main body 50 is set to be wider than the duct opening 11a, and recesses 55 in which the polarity protrusions 11c of the wiring duct 10 are disposed are provided on both sides of the top surface of the main body 50 in the width direction. The insertion portion 51 can be inserted into the wiring duct 10 through the duct opening 11a.

[0027] The pair of mounting members 53 have wiring duct mounting portions 56 that protrude from the side surfaces of the insertion portion 51. The wiring duct mounting portions 56 are formed in a claw shape, with the upper surface being an inclined surface that slopes downward toward the tip and the lower surface being an engaging surface that is perpendicular to the side surface of the insertion portion 51. The wiring duct mounting portions 56 of each mounting member 53 can advance and retreat in the width direction from the side surface of the insertion portion 51, and are detachably mounted on the support edge portion 11b of the wiring duct 10.

[0028] The operating member 54 is disposed on the main body 50 so as to be movable along the longitudinal direction, and an operating portion 57 provided on one end side thereof protrudes from one end face of the main body 50. The operating member 54 is configured to interlock with the pair of mounting members 53 via an interlocking mechanism such as a cam or rack and pinion, and is configured so that when the operating portion 57 is pushed into the main body 50 and moves, the pair of mounting members 53 move into the insertion portion 51 against the bias of the biasing member.

[0029] As shown in Figures 1 and 5, the power supply wiring duct mounting unit 23 includes a housing 60, a plug 61 that protrudes from the top surface of the housing 60 and is rotatable horizontally around an axis in the vertical direction, and an operating member 62 that rotates the plug 61.

[0030] The housing 60 is formed in approximately the same shape as the main body 50 of the housing 52 of the holding wiring duct mounting unit 22. Therefore, similar to the recessed portions 55 of the main body 50, recessed portions 60a are provided on both sides of the upper surface of the housing 60 in the width direction, where the polarity protrusions 11c of the wiring duct 10 are disposed.

[0031] The plug 61 has a resin plug body 63. The plug body 63 has a diameter (width) smaller than the width of the duct opening 11a of the wiring duct 10, allowing it to be inserted into the duct opening 11a. A pair of wiring duct mounting portions 64 and a pair of terminals 65 protrude from the side of the plug body 63. The pair of wiring duct mounting portions 64 are integral with the plug body 63, have the same width as the plug body 63, and protrude in opposite directions relative to the center of the plug body 63 so as to be engageable with and detachable from the support edge portion 11b of the wiring duct 10. The pair of terminals 65 protrude in the same direction as the pair of wiring duct mounting portions 64, above the plug body 63, and in the opposite direction relative to the center of the plug body 63. These terminals 65 are in contact with and electrically connected to the pair of conductors 13 of the wiring duct 10. The pair of terminals 65 are electrically connected to the power input portion of the power supply unit 33. This electrical connection may be made by attaching the power supply wiring duct mounting unit 23 and the lighting unit 21 so that their terminals come into contact with each other, or by electrically connecting them using wiring with a connector.

[0032] The operating member 62 is connected to the lower side of the plug body 63, and allows the pair of wiring duct mounting portions 64 and the pair of terminals 65 to rotate together between a disconnected position along the longitudinal direction of the housing 60 and a connected position along the width direction of the housing 60. The operating member 62 has an operating portion 66 arranged on one side of the housing 60, and by operating the operating portion 66, the plug 61 can be rotated.

[0033] In addition, the cover 30 may be provided with an operation window that allows the operation member 62 of the power supply wiring duct mounting unit 23 to be rotated when the lighting unit 21 is attached to the power supply wiring duct mounting unit 23.

[0034] 3 and 4, the holding wiring duct attachment unit 22 includes a magnetic force generating unit 70 for magnetically holding and attaching the lighting unit 21. The magnetic force generating unit 70 is disposed on the underside of the main body 50 of the housing 52 facing the lighting unit 21. The magnetic force generating unit 70 includes a magnet that generates magnetic force, such as a permanent magnet, and may further include a contact magnetic body through which the magnetic force from the magnet passes and contacts the magnetic body to be held.

[0035] The lighting unit 21 includes a magnetic material portion 71 that is attached to and held by magnetic force by a magnetic force generating portion 70 of the holding wiring duct mounting unit 22. The magnetic material portion 71 is formed into a plate shape using a ferromagnetic material such as an iron plate, and is attached to the upper surface of the light source mounting portion 31. One end of the magnetic material portion 71 is bent into a substantially L-shape, and this one end is attached to the upper surface of the light source mounting portion 31, while the other end is disposed at a position above and away from the light source mounting portion 31 so as to abut against the magnetic force generating portion 70 and be held by magnetic force at the position where the lighting unit 21 is attached to the holding wiring duct mounting unit 22.

[0036] 5, the power supply wiring duct mounting unit 23, like the above-described holding wiring duct mounting unit 22, is provided with a magnetic force generating unit 70 for magnetically holding and mounting the lighting unit 21. The magnetic force generating unit 70 is disposed on the underside of the housing 60 facing the lighting unit 21.

[0037] Similarly to the above, the lighting unit 21 also includes a magnetic body part 71 that is attached to the magnetic force generating part 70 of the power supply wiring duct attachment unit 23 by being held by magnetic force.

[0038] As a first example of an installation method for installing lighting device 20 in wiring duct 10, first, wiring duct mounting unit 22 for holding and wiring duct mounting unit 23 for power supply are attached to wiring duct 10, and then lighting unit 21 is attached to wiring duct mounting unit 22 for holding and wiring duct mounting unit 23 for power supply. In this case, wiring duct mounting unit 22 for holding and wiring duct mounting unit 23 for power supply are attached to wiring duct 10 with a predetermined distance therebetween corresponding to the positions of magnetic material portions 71 on both end sides of lighting unit 21.

[0039] The holding wiring duct mounting unit 22 inserts the insertion portion 51 into the duct opening 11a of the wiring duct 10 from below. During the insertion process, the inclined surfaces on the upper surfaces of the wiring duct mounting portion 56 of the mounting member 53 abut against the support edge portions 11b on both sides of the wiring duct 10, and the wiring duct mounting portion 56 retreats toward the insertion portion 51 against the bias of the biasing member. When the wiring duct mounting portion 56 is pushed up above the support edge portions 11b on both sides of the wiring duct 10, the bias of the biasing member causes the wiring duct mounting portion 56 to protrude from the side surface of the insertion portion 51 and engage with the support edge portions 11b on both sides of the wiring duct 10, and the holding wiring duct mounting unit 22 is attached to the wiring duct 10.

[0040] In the power supply wiring duct mounting unit 23, the plug 61 is inserted from below into the duct opening 11a of the wiring duct 10, and with the upper surface of the housing 60 in contact with the wiring duct 10, the operating portion 66 of the operating member 54 is operated to rotate the plug 61. When the plug 61 is rotated, the pair of wiring duct mounting portions 64 engage with the support edge portions 11b on both sides of the wiring duct 10 and are fixed by engaging between the support edge portions 11b and the insulator 12, and the pair of terminals 65 come into contact with the pair of conductors 13 of the wiring duct 10 to be electrically connected.

[0041] The lighting unit 21 is lifted and moved upward so that the wiring duct mounting units 22, 23 attached to the wiring duct 10 can be inserted into the cover 30 through the opening 38 on the top surface side.

[0042] As a result, the magnetic material parts 71 arranged on both end sides of the lighting unit 21 face the magnetic force generating parts 70 of the wiring duct mounting units 22, 23, and as they approach each other, the magnetic force generated by the magnetic force generating parts 70 attracts the magnetic material parts 71, bringing them into contact and holding them. When the magnetic force generating parts 70 and the magnetic material parts 71 are in contact with each other, the holding force due to the magnetic force is at its maximum.

[0043] As a result, both ends of the lighting unit 21 are attached to the wiring duct 10 via the wiring duct attachment units 22, 23. The wiring duct attachment unit 23 for power supply and the power supply unit 33 may be electrically connected by bringing their terminals into contact with each other when the wiring duct attachment unit 23 for power supply and the lighting unit 21 are attached, or may be electrically connected by wiring with a connector.

[0044] In this way, the installation of the lighting device 20 is completed, and the installation can be easily performed by a single worker.

[0045] As a second example of the installation method, the power supply wiring duct mounting unit 23 may be attached to the wiring duct 10, the holding wiring duct mounting unit 22 may be attached to one end of the lighting unit 21 by magnetic force, and the other end of the lighting unit 21 may be attached to the power supply wiring duct mounting unit 23 by magnetic force while the holding wiring duct mounting unit 22 attached to one end of the lighting unit 21 is attached to the wiring duct 10. In this case, the holding wiring duct mounting unit 22 can be attached to the wiring duct 10 without considering the distance from the power supply wiring duct mounting unit 23, making installation easier.

[0046] On the other hand, when removing the lighting device 20 from the wiring duct 10, first, the lighting unit 21 is moved downward against the magnetic force, and the magnetic material portions 71 on both end sides of the lighting unit 21 are moved away from the magnetic force generating portions 70 of the wiring duct mounting units 22, 23, thereby removing the lighting unit 21 from the wiring duct 10.

[0047] Thereafter, in the holding wiring duct mounting unit 22, the operating portion 57 is pushed in from the end direction of the main body portion 50, and the pair of wiring duct mounting portions 56 is moved back from the duct main body 11 into the insertion portion 51, thereby removing the pair of wiring duct mounting portions 56 from above the support edge portions 11b on both sides of the wiring duct 10, and the holding wiring duct mounting unit 22 is moved downward to remove it from the wiring duct 10.

[0048] In the power supply wiring duct mounting unit 23, the operating part 66 is operated to rotate the plug 61, and the pair of wiring duct mounting parts 64 are moved from above the support edge parts 11b on both sides of the wiring duct 10 onto the duct opening 11a, and the pair of terminals 82 are moved from the position where they contact the conductors 13 on both sides of the wiring duct 10 onto the duct opening 11a, thereby moving the power supply wiring duct mounting unit 23 downward and removing it from the wiring duct 10.

[0049] In the first embodiment, the wiring duct mounting units 22, 23 attached to the wiring duct 10 are provided with a magnetic force generating section 70, and the lighting unit 21 is provided with a magnetic material section 71, so that the lighting unit 21 is attached by being held by magnetic force and can be removed against the holding force by magnetic force, thereby improving the ease of attaching and detaching the lighting unit 21 to the wiring duct 10.

[0050] 6, the holding wiring duct mounting unit 22 may include a magnetic material portion 71, and the lighting unit 21 may include a magnetic force generator 70. In this case, a magnetic force generator mounting member 72 is used to mount the magnetic force generator 70 to the light source mounting portion 31, and the magnetic force generator mounting member 72 is used to mount the lighting unit 21 on the holding wiring duct mounting unit 22, and the magnetic force generator 70 is positioned in a position where it can come into contact with the magnetic material portion 71 and be held by magnetic force. The power supply wiring duct mounting unit 23 may also be configured in a similar manner.

[0051] In addition, one of the holding wiring duct mounting unit 22 or the power supply wiring duct mounting unit 23 may be used as an adapter to hold the lighting unit 21 by magnetic force, and the other may be fixedly attached to the lighting unit 21.

[0052] Alternatively, the lighting fixture may be attached to the wiring duct 10 using either the holding wiring duct attachment unit 22 or the power supply wiring duct attachment unit 23. When only the holding wiring duct attachment unit 22 is attached to the wiring duct 10, the lighting fixture may receive power from a feeder wiring from another lighting device placed adjacently, or a separate power supply unit may be used to receive power from the wiring duct 10.

[0053] Although several 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 embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
