[0023] FIG. 7 is a side view showing the lighting fixture 1 according to the first embodiment, and FIG. 8 is a bottom view showing the lighting fixture 1 according to the first embodiment. FIG. 9 is a front view showing the lighting fixture 1 according to the first embodiment. As shown in FIG. 7 to FIG. 9, when the lamp side connector 22 of the lighting duct unit 20 engages with the appliance side connector 16 of the appliance 10, the lighting duct unit 20 is attached to the appliance 10. In this state, an opening is formed between the appliance 10 and the lighting duct unit 20, forming an air conditioning return port 25. That is, the air conditioning return port 25 is formed between the decorative panel 24 and the peripheral portion of the appliance 10. When the lighting duct unit 20 is removed from the appliance 10, the lighting duct unit 20 is lowered downward from the appliance 10. At this time, an operator or the like inserts his or her hands into the air conditioning return ports 25 on both sides and grasps the decorative panel 24.

[0024] FIG. 10 is a side view showing a state in which the lighting device 100 is attached to the lighting fixture 1 according to the first embodiment, and FIG. 11 is a front view showing a state in which the lighting device 100 is attached to the lighting fixture 1 according to the first embodiment. As shown in FIG. 10 and FIG. 11, the lighting device 100 is fixed to the lighting duct unit 20 by being attached to the duct rail 21a of the unit body 21. The lighting device 100 is movable in the longitudinal direction by sliding along the duct rail 21a. Here, the lighting device 100 is illustrated as a spotlight or a pendant light, but may be a hanging ceiling light or the like. When the lighting device 100 is within the maximum allowable load of the lighting duct unit 20, the lighting duct unit 20 is held at a predetermined position of the fixture 10.

[0025] FIG. 12 is a side view showing a state in which the lighting device 100 is attached to the lighting fixture 1 according to the first embodiment and the maximum load is exceeded, and FIG. 13 is a front view showing a state in which the lighting device 100 is attached to the lighting fixture 1 according to the first embodiment and the maximum load is exceeded. As shown in FIG. 12 and FIG. 13, when the lighting device 100 is larger than the maximum allowable load of the lighting duct unit 20, the lighting fixture side connector 22 is not held by the curved portion 16b of the fixture side connector 16, and the lighting duct unit 20 falls due to gravity. Note that the lighting fixture side connector 22 is caught by the fall prevention portion 16c of the fixture side connector 16, so that the lighting duct unit 20 can be prevented from falling. At this time, the user or the like can visually recognize that the lighting duct unit 20 is clearly in a position lower than a predetermined position. Therefore, the user or the like can recognize that an excessive load is applied to the lighting duct unit 20. Therefore, the user or the like can take measures such as replacing the lighting device 100 with one that does not exceed the maximum load. This prevents the application of a force greater than the load that the instrument 10 can withstand, and prevents the instrument 10 from being damaged due to deformation or the instrument 10 itself from falling due to damage to the fastener that attaches the instrument 10 to the attachment portion. In this case, the electric wire 19 connected to the connector 18 is also pulled, but since it does not stretch beyond the length of the instrument-side coupler 16, it is also possible to prevent the electric wire 19 from being subjected to a load. This prevents the connector connection from coming loose and the electric wire 19 from being cut.

[0026] According to the first embodiment, the lighting fixture side connector 22 of the lighting duct unit 20 is provided on the unit body 21 on which the duct rail 21a to which the lighting device 100 is attached is provided. The lighting fixture side connector 22 engages with the fixture side connector 16 of the fixture 10, whereby the lighting duct unit 20 is attached to the fixture 10. In this manner, the lighting duct unit 20 can be provided by utilizing the fixture 10 used in the existing lighting device 100.

[0027] In the first embodiment, in an existing lighting fixture 200 (see FIG. 17) in which a luminaire 220 (see FIG. 17) is provided in a light source housing 14, various lighting devices 100 can be attached by simply removing the luminaire 220 and replacing it with the lighting duct unit 20. It is also possible to use one of the two light source housings 14 as the luminaire 220 and the other as the lighting duct unit 20. In addition, when a power source provided in the luminaire 220 and a power terminal block 17 attached to the fixture 10 are connected via a connector via an electric wire 19, the connector 18 can also be used to attach the lighting duct unit 20. In this case, it is only necessary to remove the connector connecting the fixture 10 and the existing luminaire 220 and connect the lighting duct unit 20 to the fixture 10. Therefore, the work of replacing the luminaire 220 with the lighting duct unit 20 is simple. In addition, if the luminaire 220 is a 200V system and the commercial power source connected to the power terminal block 17 is a 200V system, the power supply voltage can be reduced to be compatible with the 100V system lighting device 100 by inserting a step-down transformer at the connector connection part on the lighting duct unit 20 side.

[0028] In this way, in the first embodiment, the luminaire 220 of the lighting fixture 1 can be easily replaced with the lighting duct unit 20. This makes it possible to install stage lighting such as a spotlight or a pendant light.

[0029] Embodiment 2 Fig. 14 is a side view showing lighting fixture 1 according to embodiment 2, and Fig. 15 is a bottom view showing lighting fixture 1 according to embodiment 2. Fig. 16 is a front view showing lighting fixture 1 according to embodiment 2. Embodiment 2 differs from embodiment 1 in that unit body 21 is located closer to the irradiation target side than decorative panel 24. In embodiment 2, parts in common with embodiment 1 are given the same reference numerals and their description is omitted, and the following description will focus on the differences from embodiment 1.

[0030] 14 to 16, the unit body 21 is located closer to the irradiation target side than the decorative panel 24. Therefore, an operator can easily remove the lighting duct unit 20 from the fixture 10 by gripping both ends of the unit body 21 in the width direction and pulling the unit body 21 downward.

[0031] Lighting device 1 is not limited to the configurations of embodiments 1 and 2. The configurations of embodiments 1 and 2 are merely examples, and may include other configurations. Lighting device 1 includes the range of design modifications and application variations that are normally implemented by a person skilled in the art, within the scope that does not deviate from the technical concept. In addition, it is also possible to configure a lighting system by connecting embodiment 1 and lighting device 1 to a network.

[0032] Fig. 17 is a front view showing an existing lighting fixture 200. Fig. 18 is a front view showing a lighting fixture 1 according to a modified example. The lighting fixture 1 shown in Fig. 1 illustrates a case in which two luminaires 220 are removed from the existing lighting fixture 200 shown in Fig. 17 and lighting duct units 20 are attached to their respective positions. Note that the lighting fixture 1 shown in Fig. 18 may be obtained by leaving one luminaire 220 from the existing lighting fixture 200 shown in Fig. 17 as it is and replacing the other luminaire 220 with the lighting duct unit 20.

[0033] Furthermore, the existing lighting fixture 200 may be a one-light or three-light fixture, instead of a two-light fixture having two luminaires 220. In the case of a three-light lighting fixture 200, all of the luminaires 220 may be replaced with lighting duct units 20, or one or two luminaires 220 may be replaced with lighting duct units 20. Furthermore, the form of the lighting fixture 1 need not be a grid ceiling lighting fixture as shown in Fig. 1, but may be any lighting fixture having a mechanism for attaching and detaching the luminaire 220. For example, it may be a base light such as an inverted Fuji type, a recessed open-bottom fixture, or the like.
