  However, when the lighting fixture controlled by the DMX control signal is employed using the suspension device for the lighting fixture of Patent Document 1, the DMX control signal line is wired in addition to the power line and the power supply line for supplying power to the lighting fixture. Therefore, there is a problem that the number of wirings increases and the number of binding portions increases and the wiring becomes complicated as the number of wirings increases. In particular, recently, the use of LEDs as energy-saving measures for lighting fixtures has led to a shift from AC power source and phase angle signal control to DC power source and DMX signal control, and lighting fixtures using DMX signals tend to increase. The increase in the number of wires, the increase in the number of wires due to the increase in the number of wires, and the suppression of the complexity of the wires are major issues.

  In addition, when designing a lighting device in consideration of wiring of a power supply line, a power line, and a DMX control signal line, a complicated structure and an increase in size of the lighting device are inevitable.

The power line carrier communication converter C receives the DMX control signal transmitted from the DMX controller C1, and the power line B It is designed to be superimposed on.

  The lighting device suspension device 1 may be any device that can expand and contract to an arbitrary length in the vertical direction and has a function of adjusting the height of the suspended lighting device 2. For example, JP 2002-170423 A It is possible to use the lighting apparatus suspension device 1 having the configuration described in (1).

  The lighting device suspension apparatus 1 is provided with a handle portion 10 that performs an expansion / contraction operation of the lighting device suspension device 1, and an upper portion of the handle portion 10 is formed as an expansion / contraction portion 11 that expands and contracts. Further, a hook portion 12 for suspending the lighting device suspension device 1 is provided on a suspension bar (not shown) above the extendable portion 11.

  The luminaire 2 is suspended from the luminaire suspension device 1, and the height of the luminaire 2 is adjusted along with the expansion / contraction of the expansion / contraction portion 11 by the expansion / contraction operation of the handle portion 10. The lighting fixture 2 includes a dimming power supply circuit (not shown) that performs dimming control based on the DMX control signal described above. Light is going to be done.

  The power supply line 3 is wired at the upper end side to the power line B, and is spirally wound around the outer periphery of the expansion / contraction part 11, and the middle part of the power supply line 3 is extended downward from the spirally wound portion. Is fixed to the handle portion 10, and the lower end portion of the power supply line 3 is connected to a connection connector 30 provided on the lower end side (lower side than the handle portion 10) of the suspension device 1 for lighting equipment.

  A power supply line 20 connected to the lighting fixture 2 is connected to the connection connector 30, and the power of the power supply line 3 is supplied to the lighting fixture 2 through the power supply line 20.
