The power supply unit 25 converts the external power supplied through the power plug 84 into a predetermined lighting power for lighting the light emitting element of the light emitting module 37 and supplies the lighting power to the light emitting module 37.

The power supply unit 25 may be attached to the base 27 in the instrument body 21 in a form of being screwed, for example. In this case, since the power supply unit 25 is arranged at a position separated from the light emitting module 37, it is expected that the heat from the light emitting module 37 is less likely to be received and the temperature rise of the power supply unit 25 can be suppressed. Further, since the heat generated from the power supply unit 25 can be released to the base 27, improvement of heat dissipation can be expected.

Next, the construction of the lighting fixture 20 configured in this way will be described.

The wiring duct 10 is installed in advance on an installation surface such as a ceiling.

When constructing the lighting fixture 20, the power supply plug 84 is positioned at the connection release position shown in FIG. If the power plug 84 is located at the connection position shown in FIG. 11, the power plug 84 is rotated so as to move the operating portion 96 in the longitudinal direction of the instrument body 21, and the power plug 84 is moved to the position shown in FIG. Position it in the disconnection position shown. When the power supply plug 84 is located at the connection release position, the stopper pin 91 of the power supply plug 84 fits into the connection release position positioning hole 103 of the support body 85, and the power supply plug 84 rotates carelessly from the connection release position. Prevent it from falling.

The worker who performs the construction supports the upper portion of the insertion portion 54 of the attachment mechanism 23 arranged at both ends of the lighting fixture 20 at the opening 14 of the wiring duct 10 while supporting the lighting fixture 20 at two positions in the longitudinal direction with both hands. Fit and insert, and push up the lighting fixture 20 to the wiring duct 10.

At this time, since the height of the insertion portion 54 of the attachment mechanism 23 protruding from the upper surface of the instrument body 21 is higher than the height of the power supply plug 84, the insertion portions of the attachment mechanism 23 arranged at both ends of the instrument body 21. By fitting and inserting the upper side of 54 into the opening 14 of the wiring duct 10, the power feeding plug 84 arranged at the center of the fixture body 21 is positioned with respect to the opening 14 of the wiring duct 10, and the lighting fixture 20 The power plug 84 is automatically inserted into the opening 14 of the wiring duct 10 as it is pushed up.

By pushing up the lighting fixture 20 to the wiring duct 10, the inclined surfaces of the upper surfaces of the claw portions 71 of the claw bodies 45a and 45b protruding from both side surfaces of the insertion portion 54 of the mounting mechanism 23 cause the supporting edges 15 on both sides of the wiring duct 10 to move. And the claw portions 71 of the claw bodies 45a and 45b retract into the insertion portion 54 against the bias of the biasing members 46a and 46b.

When the claw portions 71 of the claw bodies 45a and 45b are pushed up above the support edge portions 15 on both sides of the wiring duct 10, the claw portions 71 of the claw bodies 45a and 45b are pushed by the biasing members 46a and 46b. Of the wiring duct 10 and is locked on the support edge portions 15 on both sides of the wiring duct 10.

If the attachment mechanisms 23 at both ends of the fixture main body 21 are locked to the wiring duct 10, the lighting fixture 20 is supported by the wiring duct 10 and does not fall even if the operator releases his hand from the lighting fixture 20. Although the attachment mechanisms 23 at both ends of the fixture body 21 are locked to the wiring duct 10, but the power plug 84 is not yet connected, the lighting fixture 20 can be moved along the longitudinal direction of the wiring duct 10. It is possible and the mounting position of the lighting fixture 20 can be adjusted.

Then, as shown in FIG. 11, the operation portion 96 of the power supply plug 84 located on the side surface of the device body 21 is moved in the longitudinal direction of the device body 21, and the power supply plug 84 is rotated from the disconnection position to the connection position.

By rotating the power supply plug 84 to the connection position, the pair of engaging portions 94 are engaged and fixed between the support edge portions 15 and the insulator 12 on both sides of the wiring duct 10, and the pair of terminals is formed. 95 contacts the conductors 13 on both sides of the wiring duct 10 and is electrically connected. The thickness of the engaging portion 94 is substantially the same as the distance between the supporting edge portion 15 and the insulator 12, and since there is no play in the height direction of the engaging portion 94, the lighting fixture 20 is mechanically attached to the wiring duct 10. It is fixed to and cannot be moved even along the longitudinal direction of the wiring duct 10.

Further, by rotating the power supply plug 84 to the connection position, the stopper pin 91 of the power supply plug 84 fits into the connection position positioning hole 102 of the support body 85, and the power supply plug 84 rotates carelessly from the connection position. Is prevented. Further, 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. As a result, the appearance can be improved and dust and the like can be prevented from entering the instrument body 21.

In this way, the construction of the lighting fixture 20 is completed, and even one worker can easily construct it.

Further, the plurality of lighting fixtures 20 can be arranged in the wiring duct 10 so as to be adjacent to each other. In this case, when arranging a plurality of lighting fixtures 20 adjacent to each other, in order to prevent the operating portion 77 from being pushed by the adjacent lighting fixtures 20 and the claw portion 71 of the attachment mechanism 23 from coming off from the wiring duct 10, an operation is performed. The portion 77 has a structure that does not protrude from the end surface of the lighting fixture 20. Moreover, with this structure, the operating portion 77 cannot be seen from the light irradiation direction, and therefore the design is good.

Then, by supplying a predetermined external power supply to the pair of conductors 13 of the wiring duct 10, the external power is supplied from the pair of conductors 13 to the power supply unit 25 through the pair of terminals 95 of the power plug 84. The lighting power converted by the power supply unit 25 is supplied to the light emitting module 37, the light emitting element of the light emitting module 37 is turned on, and light is applied to the illumination space through the translucent cover 39. At the time of lighting, the light emitting region of the translucent cover 39 is continuous in a line along the longitudinal direction.

When removing the lighting fixture 20, the worker first rotates the power plug 84 so as to move the operating portion 96 in the longitudinal direction of the fixture body 21, and disconnects the power plug 84 from the connection shown in FIG. To position.

By rotating the power supply plug 84 to the disconnection position, the pair of engaging portions 94 are disengaged from the supporting edge portions 15 on both sides of the wiring duct 10 and are positioned on the opening portion 14, and the pair of terminals 95 are wired. It is located on the opening 14 apart from the conductors 13 on both sides of the duct 10.

Further, by rotating the power supply plug 84 to the connection release position, the stopper pin 91 of the power supply plug 84 fits into the connection release position positioning hole 103 of the support body 85, and the power supply plug 84 is carelessly moved from the connection release position. Rotation is prevented.

Subsequently, the operator pushes the operating portion 77 of the mounting mechanism 23 from the longitudinal direction of the lighting equipment 20 while supporting the lighting equipment 20, and the claw bodies 45a protruding from both side surfaces of the insertion portion 54 of the mounting mechanism 23. , 45b retracts into the insertion portion 54 against the bias of the biasing members 46a, 46b, and the claws 71 of the claw bodies 45a, 45b are removed from the support edges 15 on both sides of the wiring duct 10.

After the claw portions 71 of the claw bodies 45a and 45b lower the lighting device 20 below the supporting edge portions 15 on both sides of the wiring duct 10, the operation of the operation portion 77 is released.

In addition, when the luminaire 20 is removed by one worker, the luminaire 20 can be removed by simultaneously removing the mounting mechanism 23 on one end side and the mounting mechanism 23 on the other end side of the luminaire 20 from the wiring duct 10. Can be removed from the wiring duct 10. At this time, since it is necessary to push the operation portion 77 of the attachment mechanism 23 while holding down the lighting equipment 20, the operation portion 77 should be arranged within a range that the finger can reach from the end of the lighting equipment 20, for example, within 40 mm. It is desirable that the mounting mechanism 23 is provided. Further, in the present embodiment, since the operating portion 77 is pushed in the longitudinal direction of the wiring duct 10, the operating portion 77 is pushed in an unstable state where the lighting fixture 20 is held down, and a strong force is applied unintentionally. Even in the case of lighting, a force is applied in the direction in which the lighting fixture 20 slides in the wiring duct 10. Workability is good because no force is applied unintentionally in the direction of removing the lighting fixture 20.

The luminaire 20 of the present embodiment configured in this way is provided with the attachment mechanism 23 detachably attached to the wiring duct 10 at both ends of the luminaire body 21 at two positions in the longitudinal direction, and further, the luminaire body 21 is attached. Since the power supply plug 84 having the terminal 95 detachably connected to the conductor 13 in the wiring duct 10 is provided between the mechanisms 23, the workability of the long lighting fixture 20 on the wiring duct 10 can be improved.

While the lighting fixture 20 is pushed up and attached to the wiring duct 10, the lighting fixture 20 is automatically held in the wiring duct 10 without pressing a button or turning a lever, for example. Therefore, even when a single worker is working, with the lighting device 20 attached to the wiring duct 10, while holding the lighting device 20 so that it does not fall, for example, pressing a button or operating a lever It is not necessary to perform the operation of holding the device 20 in the wiring duct 10, and 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 by the wiring duct 10 and does not fall even if the worker releases his hand from the lighting fixture 20. Although the attachment mechanisms 23 at both ends of the fixture body 21 are attached to the wiring duct 10, the lighting fixture 20 can be moved along the longitudinal direction of the wiring duct 10 when the power supply plug 84 is not yet connected. Thus, the mounting position of the lighting fixture 20 can be adjusted. Although the attachment mechanisms 23 at both ends of the fixture body 21 are attached to the wiring duct 10, the lighting fixture 20 also plays in the height direction with respect to the wiring duct 10 when the power plug 84 is not yet connected. It may be in a moving state due to the presence of the obstacle.

Moreover, the power supply plugs 84 can be positioned with respect to the wiring duct 10 by the mounting mechanisms 23 at both ends of the instrument main body 21 attached to the wiring duct 10, and the workability can be improved.

Furthermore, since the power supply plug 84 has the operation portion 96 arranged on the side portion intersecting the longitudinal direction of the instrument body 21, the operation portion 96 has good visibility and can be easily operated.

Further, since the power supply plug 84 is provided between the two attachment mechanisms 23 provided on the fixture body 21, even in the long lighting fixture 20, stable attachment by the two attachment mechanisms 23 and the power supply plug 84 are provided. A stable electrical connection can be achieved.

In addition, in the attachment 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 duct 10, whereas the operating portion 77 moves in the longitudinal direction of the wiring duct 10 and both sides. Since the claw portion 71 is moved, the claw portion 71 can be moved by operating one operation portion 77, and the work of attaching and detaching the wiring duct 10 can be simplified.

Moreover, the structure of the attachment mechanism 23 does not require an interlocking mechanism or the like to move the claw portions 71 on both sides, and can be simplified.

Further, since the operating portion 77 is a button for moving the claw portions 71 on both sides by a pushing operation in the longitudinal direction of the wiring duct 10, the structure is simple and the operability can be improved.

Further, the claw portion 71 projecting from one side surface of the insertion portion 54 and the claw portion 71 projecting from the other side surface are arranged at different positions in the longitudinal direction of the wiring duct 10 (insertion portion 54), so that Since it is possible to increase the moving distance of each claw portion 71 that advances and retracts from the insertion portion 54, it is possible to increase the locking width of each claw portion 71 with respect to the wiring duct 10 and securely attach to the wiring duct 10.

The attachment mechanism 23 is not limited to the positions near both ends of the instrument body 21, and may be arranged closer to the center side than both ends of the instrument body 21. Further, the attachment mechanisms 23 may be provided at three or more locations in the longitudinal direction of the instrument body 21.

Further, the power supply plug 84 is not limited to the central position of the instrument body 21, but may be a position deviated from the center of the instrument body 21, or may be disposed closer to the end of the instrument body 21 than the attachment mechanism 23.

The mounting mechanism 23 can also be applied to mounting other electric devices on the wiring duct 10.

Moreover, the lighting fixture 20 does not need to include a power supply unit. In this case, the power supply unit may be separately installed and the lighting power may be supplied from this power supply unit to the conductor 13 of the wiring duct 10.

The attachment mechanism 23 does not have to include the release button 77. In this case, the movement of the claw structure when attached to the wiring duct 10 is the same as in the above embodiment, and when removed from the wiring duct 10, it is not released by the weight of the lighting fixture 20, but with a force greater than the weight of the lighting fixture 20. The claw structure may be detached from the wiring duct 10 and can be removed only when the removing operation is performed.

In addition, as a lighting device, a power supply unit including a power supply unit may be configured separately from the light source unit, and the power supply unit and the light source unit may be electrically connected by wiring. In this case, the mounting mechanism 23 of the above-described embodiment may be applied to the power supply unit.

Further, the use of the attachment mechanism 23 shown in the present embodiment is not limited to the lighting fixture 20. As long as it is attached to the wiring duct 10 that is a rail-shaped attached portion, it can be applied to any wiring duct attachment object that is an attachment object regardless of whether or not power is supplied. Such wiring duct attachments include, for example, a power box, a sensor, a camera, a clock, a television, a painting, and the like, and the attachment mechanism 23 may be used when attaching these.

When a plurality of wiring duct attachments are attached to one wiring duct 10, the operation portion 77 of the attachment mechanism 23 is prevented in order to prevent the operation portion 77 of the attachment mechanism 23 of the adjacent wiring duct attachments from being unintentionally pushed. It is desirable that the structure does not protrude beyond the end of the wiring duct attachment. Moreover, with this structure, the operating portion 77 cannot be seen from the light irradiation direction, and therefore the design is good.
