[0014] In the following explanation and drawings, the longitudinal direction of the baton is defined as the X-axis direction, the direction in which the baton and the main body are aligned is defined as the Z-axis direction, and the direction perpendicular to the X-axis and Z-axis directions, or the up-down direction, is defined as the Y-axis direction. Note that depending on the mode of use, the Z-axis may not be the up-down direction, but for the sake of convenience, the following explanation will be given assuming that the Z-axis is the up-down direction.
[0015] (Embodiment) First, a lighting system 10 according to an embodiment will be described. Fig. 1 is a plan view showing a schematic configuration of the lighting system 10 according to the embodiment. Fig. 2 is a cross-sectional view showing a schematic configuration of the lighting system 10 according to the embodiment. Note that Fig. 1 shows the back side of a lighting fixture 20.
[0016] 1 and 2, the lighting system 10 includes lighting fixtures 20 and a baton device 30 that suspends and supports the lighting fixtures 20. In this embodiment, an example is shown in which four lighting fixtures 20 are supported by the baton device 30, but the number of lighting fixtures 20 installed may be any number as long as it is one or more.
[0017] The lighting fixtures 20 are spotlights that use LEDs (Light Emitting Diodes) as their light source, and are suspended and supported by a baton switch 30 to illuminate a stage, studio, or the like. A power cable 21 and a communication cable 22 are connected to the back of each lighting fixture 20. One power cable 21 is provided for each lighting fixture 20, and is connected to a power supply unit 35 provided on the baton switch 30. The communication cable 22 is provided in a single line between the two lighting fixtures 20, and is connected to a communication connection unit 36 provided on the baton switch 30. Specifically, two communication cables 22 are provided for each of the two lighting fixtures 20. One end of the first communication cable 22 is connected to the communication connection unit 36, and the other end is connected to a communication input terminal of the first lighting fixture 20. The second communication cable 22 is connected to a communication output terminal of the first lighting fixture 20, and the other end is connected to a communication input terminal of the second lighting fixture 20.
[0018] The baton device 30 includes a main body 31, a plurality of support portions 32, a baton 33, a rail portion 34, a plurality of power supply portions 35, and a plurality of communication connection portions 36.
[0019] Main body 31 is a base for suspending baton 33 and is formed long in the X-axis direction. When viewed from the Y-axis direction, main body 31 has a rectangular shape with a pair of corners 311, 312 at its bottom that are cut out in a chamfered shape. Of the pair of corners 311, 312, corner 311 facing the negative Y-axis direction is provided with rail 34.
[0020] The top surface of main body 31 faces the ceiling, and the bottom surface faces the floor. A power supply unit, a control unit, and the like are provided inside main body 31. The power supply unit is connected to a commercial power source and supplies power from the commercial power source to each lighting fixture via each power feed unit 35. The control unit is a microcomputer or the like that controls each lighting fixture 20 via communication connection unit 36 and communication cable 22.
[0021] The plurality of support parts 32 are hook-shaped members that suspend and support the batons 33 while connected to the main body part 31. In the present embodiment, the case where there are two support parts 32 is exemplified, but the number of support parts 32 installed may be three or more.
[0022] Each support portion 32 is disposed at both ends of the main body portion 31 in the X-axis direction, and extends in the negative Z-axis direction from the bottom surface of the main body portion 31. Each support portion 32 supports a baton 33 at its lower end.
[0023] The baton 33 is a cylindrical rod, and is supported by each support portion 32 so that it is positioned along the X-axis direction. Therefore, the longitudinal direction of the baton 33 is the X-axis direction. The baton 33 suspends and supports each lighting fixture 20, and also supports the communication cable 22 connected to the communication connection portion 36.
[0024] The rail portion 34 is a portion that supports a plurality of power supply units 35 so that they can slide freely in the X-axis direction. The rail portion 34 has grooves 341 that extend in the X-axis direction, and each power supply unit 35 is fitted into and supported in this groove 341. A pair of conductors 342 that are electrically connected to each power supply unit 35 are disposed in the grooves 341. Each conductor 342 is a flat, conductive member that extends along the X-axis direction and is disposed at a predetermined interval from each other. Each conductor 342 has a different polarity.
[0025] The rail portion 34 is a member that extends in the X-axis direction over the entire length of the main body portion 31. Therefore, it can be said that the rail portion 34 is provided between a plurality of support portions 32. Furthermore, as described above, the rail portion 34 is fixed to the corner portions 311 of the main body portion 31. As a result, the rail portion 34 is arranged in the main body portion 31 with the groove portion 341 facing the baton 33 side. Therefore, each conductor portion 342 arranged in the groove portion 341 is inclined at an angle that progresses in the negative Z-axis direction as it progresses in the negative Y-axis direction.
[0026] Here, "groove portion 341 facing the baton 33" does not only mean that opening 343 of groove portion 341 faces completely toward baton 33, but also means that opening 343 faces in the direction in which baton 33 is present. In this embodiment, since baton 33 is present in the negative Z-axis direction of main body portion 31, opening 343 of groove portion 341 is tilted more toward the negative Z-axis direction than the negative Y-axis direction. This case is also included in "groove portion 341 facing the baton 33." Specifically, the angle α (acute angle) formed by the opening surface of groove portion 341 and the bottom surface of main body portion 31 is in the range of 0 degrees or more and 45 degrees or less.
[0027] With rail portion 34 disposed on main body portion 31 in this position, opening 343 of groove portion 341 faces diagonally downward. Therefore, dust floating in the air is less likely to enter groove portion 341, and even if it does enter, dust is less likely to accumulate on each conductor portion 342 because each conductor portion 342 is tilted.
[0028] Each power supply unit 35 is an outlet for supplying power to lighting fixture 20. Each power supply unit 35 is detachable from rail portion 34, and when attached to rail portion 34, it is connected to each conductor portion 342 in groove portion 341 and is ready to supply power. In this state, power supply unit 35 is slidable in the X-axis direction by rail portion 34. When power cable 21 of lighting fixture 20 is connected to power supply unit 35, power is supplied from power supply unit 35 to each lighting fixture 20 via power cable 21.
[0029] Each communication connection part 36 is a connector to which a communication cable 22 is connected. Each communication connection part 36 is disposed at both ends in the X-axis direction on the side surface of the main body part 31 facing the negative Y-axis direction. Each communication connection part 36 is disposed in the positive Z-axis direction of the rail part 34. In other words, the rail part 34 is disposed closer to the baton 33 than each communication connection part 36.
[0030] Such a baton device 30 is raised and lowered relative to the ceiling by a lifting device 40 (see FIG. 3). FIG. 3 is an explanatory diagram showing a baton lifting system 50 including the baton device 30 and the lifting device 40 according to an embodiment. FIG. 3 shows a state in which the lighting fixture 20 has been removed from the baton device 30.
[0031] As shown in FIG. 3 , the lifting device 40 includes a plurality of wires 41 and a winch 42 that winds up each wire 41. A pair of connecting parts 37, to which the wires 41 of the lifting device 40 are connected, are arranged on the top surface of the main body 31 of the baton device 30 at a distance in the X-axis direction. A connection box 38, to which power supply wiring and communication wiring are connected, is also arranged on the top surface of the main body 31, between the pair of connecting parts 37. Each wire 41 is connected to the winch 42 via a pulley 51 attached to the ceiling. The winch 42 lifts the baton device 30 by winding up each wire 41. Meanwhile, the winch 42 lowers the baton device 30 by winding down each wire 41.
[0032] When the baton device 30 is suspended from the lifting device 40, the rail portion 34 is in a position where the opening 343 of the groove portion 341 is tilted downward relative to the horizontal plane. In this way, even when suspended from the lifting device 40, the opening 343 of the groove portion 341 is tilted downward, so that dust is less likely to enter the groove portion 341, and even if dust does enter, the tilt of each conductor portion 342 makes it less likely for dust to accumulate on each conductor portion 342.
[0033] As described above, according to the above embodiment, the grooves 341 of the rails 34 are disposed on the main body 31 in a position facing the batons 33, so that dust is less likely to enter the grooves 341, and even if dust does enter, it is less likely to accumulate on the conductors 342. In this way, dust accumulation on the conductors 342 is suppressed, and the electrical connection status can be stabilized.
[0034] The rail portion 34 is disposed on the main body portion 31 with the opening surface of the groove portion 341 tilted at an angle between 0 and 45 degrees relative to the bottom surface of the main body portion 31, which further prevents dust from entering the groove portion 341. Furthermore, the inclination of each conductor portion 342 can be made larger, so even if dust does enter the groove portion 341, the amount of dust that accumulates on each conductor portion 342 can be further reduced.
[0035] When the baton device 30 is suspended from the lifting device 40, the groove portion 341 of the rail portion 34 is inclined downward relative to the horizontal plane, so that accumulation of dust on each conductor portion 342 can be suppressed even when the baton device 30 is suspended from the lifting device 40.
[0036] Since the rail portion 34 is provided between the plurality of support portions 32 , the power supply portion 35 can be slid on the rail portion 34 at least between the plurality of support portions 32 .
[0037] Because power supply unit 35 is a receptacle that can be attached to and detached from rail unit 34, power supply unit 35 can be removed from rail unit 34. In other words, the number of power supply units 35 installed can be adjusted to correspond to the number of lighting fixtures 20 installed.
[0038] Since the communication connection part 36 to which the communication cable 22 is connected is provided on the main body part 31, the lighting fixture 20 and the communication connection part 36 can be connected via the communication cable 22.
[0039] Rail portion 34 is disposed closer to baton 33 than each communication connection portion 36. In other words, rail portion 34 is disposed lower than each communication connection portion 36, so that power supply portion 35 can be easily slid relative to rail portion 34 and attached / detached.
[0040] (Variation) The following describes various modifications of the above embodiment. In the following description, the same parts as those in the above embodiment or other modifications are designated by the same reference numerals, and the description thereof may be omitted.
[0041] (Variation 1) FIG. 4 is a plan view showing a schematic configuration of a lighting system 10A according to Modification 1. FIG. 5 is a cross-sectional view showing a schematic configuration of a lighting system 10A according to Modification 1. FIG. 4 corresponds to FIG. 1, and FIG. 5 corresponds to FIG. 2. As shown in FIGS. 4 and 5, in a baton device 30a provided in the lighting system 10A, a rail portion 34a is fixed to the bottom surface of a main body portion 31. The rail portion 34a is arranged on the main body portion 31 with a groove portion 341 facing the baton 33. In other words, when the baton device 30a is suspended from the lifting device 40, the opening 343 of the groove portion 341 faces directly downward, thereby further preventing dust from entering the groove portion 341. Furthermore, since each conductor portion 342 is also arranged along the vertical direction, even if dust enters the groove portion 341, the amount of dust accumulating on each conductor portion 342 can be further reduced.
[0042] (Variation 2) FIG. 6 is a plan view showing a schematic configuration of lighting system 10B according to Modification 2. FIG. 6 is a view corresponding to FIG. 1. As shown in FIG. 6, cover 39b is attached to rail 34b of lighting system 10B, covering portions of groove 341 where power supply units 35 are not arranged. Cover 39b is a sheet material that can be attached and detached to groove 341. The sheet material may be a stretchable curtain body. In this way, cover 39b covers portions of groove 341 where power supply units 35 are not arranged, thereby more reliably preventing dust from entering groove 341.
[0043] (Variation 3) Fig. 7 is a perspective view showing a schematic configuration of a lighting system 10C according to Modification 3. As shown in Fig. 7, in a baton device 30c provided in the lighting system 10C, a plurality of mounting portions 360c to which communication connection portions 36c are attached are provided on a main body 31c. In the present embodiment, a case where four mounting portions 360c are provided is exemplified, but the number of mounting portions 360c provided may be any number.
[0044] The multiple mounting portions 360c are arranged along the X-axis direction. Each mounting portion 360c is an opening extending in the X-axis direction. The communication connection portion 36c is supported by fitting into this opening. The communication connection portion 36c can be arranged at any position in the X-axis direction on each mounting portion 360c. At least one communication connection portion 36c may be attached to each mounting portion 360c so as to be slidable in the X-axis direction. The communication connection portion 36c may be detachable from each mounting portion 360c.
[0045] In this way, since the attachment portion 360c is provided on the main body portion 31c, the attachment portion 360c allows the communication connection portion 36c to be disposed at any position in the X-axis direction.
[0046] Furthermore, because attachment portion 360c is an opening that extends in the X-axis direction, communication connection portion 36c can be supported so that it can slide freely in the X-axis direction. That is, the position of communication connection portion 36c in the X-axis direction can be adjusted with a simple configuration.
[0047] The mounting portion 360c may be a rail extending in the X-axis direction. In this case, the communication connection portion 360c can be supported so as to be slidable in the X-axis direction.
