Therefore, the lighting fixture 20 is mechanically fixed to the wiring groove 10 and cannot be The wiring duct 10 moves in the longitudinal direction.

Further, when the power supply pin 84 is rotated to the connection position, the stopper pin 91 of the power supply pin 84 is fitted into the connection position positioning hole 102 of the support body 85, thereby preventing the power supply pin 84 from turning from the connection position inadvertently. In addition, the closing portion 97 of the operation member 89 of the power supply plug 84 closes the operation opening 33 of the instrument body 21 . Thereby, while the appearance can be improved, the entry of dust and the like into the instrument body 21 can be reduced.

In this way, the construction of the lighting fixture 20 is completed, and the construction can be easily performed even by one operator.

In addition, a plurality of lighting fixtures 20 may be arranged adjacent to each other in the wiring duct 10 . At this time, when a plurality of lighting fixtures 20 are arranged adjacently, in order to prevent the claw portion 71 of the mounting mechanism 23 from falling off from the wiring groove 10 due to the operation portion 77 being pressed by the adjacent lighting fixture 20 , the operation portion 77 is not driven from the wiring groove 10 . The structure in which the end surface of the lighting fixture 20 protrudes. Moreover, according to this structure, since the operation part 77 cannot be seen from the light irradiation direction, the design property is favorable.

Furthermore, since the pair of conductors 13 of the wiring duct 10 is electrically connected to a predetermined external power source, the external power source can be supplied to the power supply unit 25 from the pair of conductors 13 through the pair of terminals of the power supply plug 84 . The power supply unit 25 converts the external power into lighting power and supplies it to the light-emitting module 37 , so that the light-emitting elements of the light-emitting module 37 are turned on, and the light thereof passes through the light-transmitting cover 39 to illuminate the lighting space. At the time of lighting, the light-emitting region of the light-transmitting cover 39 is continuous in a linear shape along the longitudinal direction.

When the lighting fixture 20 is removed, the operator first turns the operation portion 96 in the longitudinal direction of the fixture body 21 to rotate the power supply latch 84 so that the power supply latch 84 is at the disconnection position as shown in FIG. 10 .

When the power supply latch 84 is rotated to the disconnected position, the pair of engaging portions 94 are disengaged from the support edge portions 15 on both sides of the wiring groove 10 to be positioned on the opening portion 14 , and the pair of terminals 95 are removed from the wiring groove 10 . The conductors 13 on both sides are separated and located on the opening portion 14 .

Then, by rotating the power supply latch 84 to the disconnection position, the stopper pin 91 of the power supply latch 84 fits into the disconnection position positioning hole 103 of the support body 85, thereby preventing the power supply latch 84 from turning from the disconnection position inadvertently.

Next, the operator presses the operation portion 77 of the mounting mechanism 23 from the longitudinal direction of the lighting fixture 20 while supporting the lighting fixture 20 with his hands, so that the claw bodies 45 a and 45 b of the mounting mechanism 23 protruding from both side surfaces of the insertion portion 54 resist the The urging members 46 a and 46 b retreat into the insertion portion 54 , and the claw portions 71 of the claw bodies 45 a and 45 b are removed from the support edge portions 15 on both sides of the wiring groove 10 .

After the lighting fixture 20 is lowered so that the claw portions 71 of the claw bodies 45a and 45b are lowered to a position lower than the support edge portions 15 on both sides of the wiring groove 10, the operation of the operation portion 77 is released.

In addition, when the lighting fixture 20 is detached by one operator, the mounting mechanism 23 on the one end side and the mounting mechanism 23 on the other end side of the lighting fixture 20 can be simultaneously removed from the wiring trough 10, so that the lighting fixture 20 can be removed from the wiring trough 10 at the same time. Remove the lighting fixture 20 . In this case, since it is necessary to press the operation part 77 of the attachment mechanism 23 while pressing the lighting fixture 20 , it is preferable to arrange the attachment mechanism 23 so that the operation part 77 is located within a range that can be reached from the end of the lighting fixture 20 with a finger. (For example, within 40mm). Furthermore, in the present embodiment, since the operation portion 77 is pressed along the longitudinal direction of the wiring duct 10 , unintended force is applied even when the operation portion 77 is pressed in an unstable state in which the lighting fixture 20 is pressed. In the case of , the force is also applied in the direction in which the lighting fixture 20 is slid along the wiring groove 10 . Since the unintended force in the direction in which the lighting fixture 20 falls off is not applied, the operability is good.

The lighting fixture 20 according to the present embodiment having the above-described structure includes attachment mechanisms 23 detachably attached to the wiring groove 10 at two positions (ie, both ends) in the longitudinal direction of the fixture body 21 , and further, the fixture body 21 A power supply pin 84 having a terminal 95 detachably connected to the conductor 13 in the wiring duct 10 is provided between the mounting mechanisms 23, so even if a long lighting fixture 20 is used, it is possible to improve the power supply relative to the wiring duct 10. Constructability.

The lighting fixture 20 can be automatically held in the wiring groove 10 without performing operations such as pressing a button or rotating an operating lever other than the operation of pushing the lighting fixture 20 upward and attaching it to the wiring groove 10 . Therefore, even when the operation is performed by one operator, in the state where the lighting fixture 20 is attached to the wiring duct 10, it is not necessary to push the lighting fixture 20 to avoid dropping, for example, by pressing a button or operating a lever. Since the operation of holding the lighting fixture 20 in the wiring duct 10 is performed, the workability is good.

When the attachment mechanisms 23 at both ends of the fixture body 21 are attached to the wiring duct 10 , the lighting fixture 20 is held in the wiring duct 10 , and the lighting fixture 20 does not drop even if the operator releases the hand from the lighting fixture 20 . When the attachment mechanisms 23 at both ends of the fixture body 21 are attached to the wiring trough 10 and the power supply pins 84 are not connected, the lighting fixture 20 can move in the longitudinal direction of the wiring trough 10 , so that the mounting position of the lighting fixture 20 can be adjusted. In addition, the lighting fixture 20 may be movable with play in the height direction with respect to the wiring trough 10 even in a state where the attachment mechanisms 23 at both ends of the fixture body 21 are attached to the wiring trough 10 and the power supply pins 84 are not connected. status.

Furthermore, by the attachment mechanisms 23 attached to both ends of the appliance main body 21 of the wiring duct 10 , the power feeding pins 84 can be positioned with respect to the wiring duct 10 , and workability can be improved.

Furthermore, since the power supply plug 84 has the operation part 96 arrange|positioned at the side part which cross|intersects the longitudinal direction of the instrument main body 21, the visibility of the operation part 96 becomes good, and it can operate easily.

Furthermore, since the power supply pins 84 are provided between the attachment mechanisms 23 arranged at the two positions of the fixture main body 21, even if a long-sized lighting fixture 20 is used, it is possible to realize stable stability by the attachment mechanisms 23 at the two positions. Install and make a stable electrical connection through the power supply pin 84 .

In addition, with regard to the mounting mechanism 23, the claw portions 71 on both sides of the insertion portion 54 move in a direction intersecting the longitudinal direction of the wiring groove 10, and the operation portion 77 moves in the longitudinal direction of the wiring groove 10, so that the Since the claw portion 71 moves, the claw portion 71 can be moved by the operation of one operation portion 77 , so that the attachment and detachment work with respect to the wiring groove 10 can be simplified.

In addition, the structure of the attachment mechanism 23 does not require a linkage mechanism or the like when moving the both-sides claw portions 71, so that the structure can be simplified.

Moreover, since the operation part 77 is a button which moves the both-side claw part 71 by the pressing operation from the longitudinal direction of the wiring groove 10, the structure is simple, and operability can be improved.

Further, the claw portion 71 protruding from one side surface of the insertion portion 54 and the claw portion 71 protruding from the other side surface are arranged at different positions shifted from each other in the longitudinal direction of the wiring groove 10 (the insertion portion 54 ). Accordingly, since the moving distance of each claw portion 71 advancing and retracting from the insertion portion 54 can be increased, the locking width of each claw portion 71 with respect to the wiring groove 10 can be increased, and it can be securely attached to the wiring groove 10 .

In addition, the attachment mechanism 23 is not limited to being arrange|positioned at the position near the both ends of the apparatus main body 21, and may be arrange|positioned at the position of the center side of the apparatus main body 21 rather than both ends. In addition, the attachment mechanisms 23 may be provided at three or more locations in the longitudinal direction of the instrument body 21 .

Furthermore, the power feeder pin 84 is not limited to being located at the center of the device body 21 , but may be located at a position deviated from the center of the device body 21 , or may be located closer to the end of the device body 21 than the attachment mechanism 23 .

In addition, the mounting mechanism 23 can also be applied to the case where other electronic devices are mounted on the wiring duct 10 .

In addition, the lighting fixture 20 may not include a power supply unit. In this case, a power supply unit may be separately provided, and lighting power may be supplied from the power supply unit to the conductors 13 of the wiring duct 10 .

In addition, the mounting mechanism 23 may not include the release button 77 . In this case, the operation of the claw structure when attached to the wiring trough 10 is the same as that of the above-described embodiment, and when detaching from the wiring trough 10, the self-weight of the lighting fixture 20 alone cannot be released. If the force of 20 or more self-weight performs the detachment operation, the claw structure is detached from the wiring groove 10 and can be detached.

Moreover, as a lighting fixture, the power supply part and the light source part provided with a power supply unit may be comprised separately, and the structure which electrically connects the power supply part and the light source part with a wiring may be employ|adopted. In this case, the attachment mechanism 23 of the above-described embodiment can be applied to the power supply unit.

In addition, the attachment mechanism 23 shown in the present embodiment is not limited to the lighting fixture 20 . As long as it can be attached to a rail-shaped attached part (that is, the wiring duct 10 ), it can be applied to any attachment object (wiring duct attachment) regardless of whether it is energized or not. As such a wiring duct mounting object, for example, a power box, a sensor, a camera, a clock, a television, a painting, etc. can be used, and the mounting mechanism 23 can be used when these are mounted.

In addition, in order to prevent the operation part 77 of the attachment mechanism 23 of the adjacent wiring trough attachment from being pressed unintentionally when a plurality of wiring trough attachments are attached to one wiring trough 10, it is preferable to use the operation part 77 for the attachment mechanism 23.
