  Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof. FIG. 1 is an explanatory view showing an example of the configuration of the illumination system 100 of the present embodiment, and FIG. 2 is an external perspective view showing an example of the configuration of the wiring duct 1 of the present embodiment. The lighting system 100 includes a wiring duct 1, a lighting device 5 attached to the wiring duct 1, and the like. For example, the wiring duct 1 has a rectangular cross-sectional shape, has a U shape in which one surface is open and three surfaces are surrounded by side plates, and is fixed to a mounting portion such as a ceiling surface or a wall surface. The lighting device 5 is attached to the wiring duct 1 through the opening on one surface of the wiring duct 1. In addition, although the example of FIG. 1 shows the state where one lighting device 5 is attached, a plurality of lighting devices can be attached. Further, a plurality of wiring ducts can be connected, and the length can be set to a desired length by increasing or decreasing the number of connections. Moreover, the wiring duct 1 illustrated in FIGS. 1 and 2 is schematically illustrated, and the length of the wiring duct 1 is sufficiently longer than that illustrated.

  As shown in FIG. 2, the wiring duct 1 has, for example, a U-shape in which a cross-sectional shape is a rectangular shape, one surface is open and three surfaces are surrounded by side plates 11, 12, and 13. A pair of power supply buses 15 is disposed inside the opposing side plates 12 and 13. An AC voltage from a commercial power source is supplied to the power supply bus 15 through a power supply unit described later. In the example of FIG. 2, a so-called two-pole power supply bus is provided, but a three-pole having a grounding bus may be used. In addition, the structure of the wiring duct 1 is prescribed | regulated by JISC8366 etc.

  The wiring duct 1 includes an optical transmission member 2 made of synthetic resin juxtaposed with the power supply bus 15. The optical transmission member 2 can be provided in parallel with the power supply bus 15 on the outside or the inside of the side plates 12 and 13 of the wiring duct 1. Moreover, the optical transmission member 2 can use, for example, a synthetic resin that guides light such as acrylic and polycarbonate. The light transmission member 2 may be transparent or colored.

  Since an optical signal can be transmitted along the longitudinal direction of the power supply bus 15 via the optical transmission member 2, a control signal (for example, a dimming signal, etc.) for controlling the illumination device 5 attached to the wiring duct 1 can be used. There is no need to wire signal lines for toning signals and the like. Further, even when a plurality of lighting devices are attached to the wiring duct 1, the control signal can be transmitted to all the lighting devices through the light transmission member 2. There is no need to operate the remote control individually. In this way, the lighting device attached to the wiring duct 1 can be easily controlled.

  3 is a cross-sectional view of the wiring duct 1 before the lighting device 5 is attached, and FIG. 4 is a cross-sectional view of the wiring duct 1 after the lighting device 5 is attached. As shown in FIG. 3, on each opening side of the side plates 12 and 13 (that is, the side opposite to the side plate 11), a support portion 14 that supports the lighting device 5 extending inward is provided. Further, the width of the side plate 12 is longer than the width of the side plate 13, and a polarity display portion 16 for displaying the polarity of the power supply bus 15 is provided at the end of the side plate 12.

  As shown in FIG. 3, the light transmission member 2 is provided on the outside of the side plate 13, that is, on the side surface of the wiring duct 1. In the example of FIG. 3, the cross-sectional shape of the light transmission member 2 is a rectangular shape, but the cross-sectional shape is not limited to a rectangular shape. The optical transmission member 2 may be individually attached to the side plate 13 of the wiring duct 1 with, for example, a double-sided adhesive tape, an adhesive, or the like, or a protrusion is formed on the surface that contacts the side plate 13 of the optical transmission member 2. It can also be set as the structure which provided the fitting hole which a projection part fits in the side plate 13. FIG.

  On one surface of the optical transmission member 2, that is, the opening-side surface of the wiring duct 1, a light emission surface 21 is formed along the length direction of the power supply bus 15. The discharge surface 21 may be a flat surface, and may form a V-shaped groove as will be described later.

  As shown in FIG. 4, the lighting device 5 includes a plug structure so that it can be attached to the wiring duct 1. The plug structure includes, for example, a placement portion 54 for placing the lighting device 5 on the support portion 14, an electrode portion 55 electrically connected to the power supply bus 15, and the like. It is defined to have a predetermined dimension.

  The illuminating device 5 includes a light receiving unit 52 at a position facing the emission surface 21 in a state of being attached to the wiring duct 1. The distance between the emission surface 21 and the light receiving unit 52 is, for example, about 3 to 5 mm. Since the light emission surface 21 is formed along the length direction of the power supply bus 15, even when the illumination device 5 is attached to a desired position of the wiring duct 1, the light receiving portion 52 of the illumination device 5 is provided with the emission surface 21. Therefore, the illumination device 5 can receive the control signal.

  FIG. 5 is an external perspective view showing an example of the structure of the optical transmission member 2. As shown in FIG. 5, V-shaped grooves 211 as concavo-convex portions formed in a direction intersecting with the length direction of the power supply bus 15 are arranged along the length direction of the power supply bus 15 on all the emission surfaces 21. It is. Note that the concavo-convex portion is not limited to the V-shaped groove, and a reflection pattern by printing or the like can be provided as a process for extracting an optical signal on the radiation surface.

  By providing the V-shaped groove 211, the amount of light (optical signal) transmitted from the emitting surface 21 to the outside without being totally reflected inside the emitting surface 21 is increased, and the light receiving unit 52 of the lighting device 5 can easily receive the optical signal. can do. Further, since the V-shaped groove 211 is provided on the entire emission surface 21, the light receiving unit 52 can easily receive the optical signal regardless of where the illumination device 5 is attached in the wiring duct 1.

  Further, in place of the example of FIG. 5, a V-shaped groove 211 may be provided in a part of the emission surface 21. For example, the V-shaped groove 211 is provided in the emission surface 21 corresponding to the position or range assumed as the position or range where the lighting device is attached in the length direction of the wiring duct 1. In this case, since the amount of light emitted from the emission surface 21 provided with the V-shaped groove 211 to the outside and from other places is reduced, the light reaches the end of the wiring duct 1 while suppressing attenuation of the optical signal. A signal can be transmitted.

  FIG. 6 is an explanatory diagram showing an example of the dimming signal. The optical transmission member 2 can transmit an optical signal obtained by modulating a dimming signal with infrared rays (for example, a wavelength between 750 and 1000 nm). The optical signal transmitted through the optical transmission member 2 can be a control signal for controlling the lighting device, and is not limited to the dimming signal. For example, the toning signal, the lighting signal, or the extinguishing signal Etc. In addition, the optical signal in the present embodiment is not limited to infrared light, but may be an optical signal of other wavelengths such as visible light.

  As shown in FIG. 6, the dimming signal is a PWM signal having a frequency of 1 kHz. For example, when the dimming signal is always at a low level (L), the dimming signal is 100% dimming (all lamps). Therefore, when there is no dimming signal, all lights are turned on. Further, when the high level (H) period and the low level (L) period are each 0.5 ms, the light control is 50%. Further, when the level is always high (H), the light control is 0% (off).

  Note that the control signals such as the dimming signal and the toning signal are not limited to the example in FIG. 6. For example, the light emission of the light emitting element of the optical signal is modulated at a frequency of about 38 kHz, and the optical signal is at a high level. Information can also be transmitted by assigning 1 or 0 bits according to the time at (H) and the time at the low level (L).

  The attachment position of the optical transmission member 2 to the wiring duct 1 is not limited to the examples of FIGS. Hereinafter, other mounting positions of the optical transmission member 2 will be described.

  FIG. 7 is an explanatory view showing another first example of the mounting position of the optical transmission member 2. As shown in FIG. 7, the light transmission member 2 can be attached to the outside of the side plate 12 facing the side plate 13 instead of the outside of the side plate 13. In this case, it is necessary to change the mounting position of the light receiving unit 52 of the illumination device 5 from that in FIG. 4 so as to face the emission surface 21.

  FIG. 8 is an explanatory view showing another second example of the mounting position of the optical transmission member 2. As shown in FIG. 8, the light transmission member 2 can be attached adjacent to a support portion 14 extending from the side plate 13 instead of the outside of the side plate 13. In this case as well, the light receiving part 52 of the illumination device 5 needs to be changed in the mounting position so as to face the emission surface 21.

  FIG. 9 is an explanatory view showing another third example of the mounting position of the optical transmission member 2. As shown in FIG. 9, the optical transmission member 2 can be attached to a gap having an L-shaped cross section defined by a support portion 14 extending from the side plate 12 and a polarity display portion 16. In this case as well, the light receiving part 52 of the illumination device 5 needs to be changed in the mounting position so as to face the emission surface 21.

  FIG. 10 is a main part external view showing an example of the configuration of the power supply unit 6 of the present embodiment, and FIG. 11 is an explanatory diagram showing an example of the case where the power supply unit 6 is connected to the wiring duct 1. As shown in FIG. 10, the power supply unit 6 includes a main body 60, a light emitting element 61, a dimming remote control light receiving unit 62, a fixing unit 63 for fitting into the wiring duct 1, a power supply electrode 64, and the like.

  The power supply unit 6 includes a power plug (not shown), is connected to a commercial power supply by connecting the power plug to an outlet, and an AC voltage is applied to the power supply electrode 64. The power feeding unit 6 has a built-in dimmer function. When the dimming remote control light receiving unit 62 receives a dimming signal from the remote control, the dimming illustrated in FIG. 6 is performed according to the received dimming signal. A signal (optical signal) is emitted from the light emitting element 61. Note that the method of wiring the power supply unit 6 to the commercial power supply is not limited to the above method, and the power supply unit 6 may be wired by being directly connected to the power supply line on the back of the ceiling or the ceiling surface.

  As described above, the power supply unit 6 includes the light emitting element 61 for making an optical signal incident on one end of the optical transmission member 2. Therefore, the optical signal can be transmitted only by attaching the power supply unit 6 to the one end 17 of the wiring duct 1. Can be transmitted.

  As shown in FIG. 11, the optical transmission member 2 has an incident surface 22 on one end where an optical signal is incident, and a light emitting portion of a light emitting element 61 that emits an optical signal is inserted into the incident surface 22. An insertion portion (insertion hole) 221 is provided. Thereby, the light emitted from the light emitting element 61 can be incident on the inside of the light transmission member 2 without leakage.

  The above-described power supply unit 6 is configured to receive a dimming signal or a toning signal from a remote controller, but is not limited thereto, and feeds a signal line from a dimmer attached to a wall or the like. A light control signal (light signal) may be emitted from the light emitting element 61 based on a signal connected to the unit and acquired by the power supply unit from the light control device. In addition, an operation unit may be provided in the power supply unit 6, and an optical signal may be transmitted and adjusted from the light emitting element 61 of the power supply unit by operating the operation unit.

  In the above-described embodiment, the example in which the LED is used as the light source of the lighting device has been described. However, the light source is not limited to the LED, and can be applied to other light sources such as EL (Electro-Luminescence).
