[0007] [Figure 1] 1 is a schematic side view of a lighting device showing a first embodiment. [Diagram 2] FIG. 11 is a schematic side view of a lighting system including a plurality of lighting devices according to a second embodiment. [Diagram 3] FIG. 2 is a schematic plan view of a fixture mounting device of the lighting system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The first embodiment will be described below with reference to FIG.

[0009] The lighting device 10 is installed on an installation surface 11 such as a ceiling surface. The lighting device 10 includes an appliance mounting device 12 that is attached to the installation surface 11, and a lighting appliance 13 that is detachably attached to the appliance mounting device 12.

[0010] The fixture mounting device 12 is attached to a hanging bolt protruding downward from the installation surface 11, or is attached to the installation surface 11 by screwing.

[0011] The instrument mounting device 12 includes an instrument main body 16, an installation-side mounting surface 17 provided on the upper surface of the instrument main body 16, and an instrument mounting surface 18 provided on the lower surface opposite the installation-side mounting surface 17. The installation-side mounting surface 17 is attached to face the installation surface 11. The shape of the instrument mounting device 12 in a plan view is rectangular, but it may be a polygon other than a rectangle or a circle. .

[0012] The appliance mounting device 12 includes a power transmission unit (also referred to as a first power transmission unit) 19 that transmits power by a wireless power supply system. The power transmission unit 19 is disposed at a predetermined position, for example, at a central position, on the appliance mounting surface 18 of the device body 16. A power line 20 drawn from the installation surface 11 is electrically connected to the power transmission unit 19.

[0013] The power transmitting unit 19 includes a power transmitting circuit that converts AC power supplied from a commercial AC power source through a power line 20 into power for transmission, and a power transmitting means that wirelessly transmits the power. Wireless power supply methods include an electromagnetic induction method, an electric field coupling method, an electromagnetic wave method (microwave, laser), etc., and any method may be used.

[0014] In addition, the fixture mounting device 12 may be attached to a ceiling hook body installed on the installation surface 11, in which case power is supplied to the power transmission unit 19 from the ceiling hook body.

[0015] The lighting fixture 13 further includes a fixture body 22, a light source (not shown) disposed in the fixture body 22, and a lighting unit (not shown) for turning on the light source. The lighting fixture 13 is detachably attached to the fixture mounting surface 18 of the fixture mounting device 12 by a mounting portion 23.

[0016] The mounting portion 23 may be provided on either the fixture mounting device 12 or the lighting fixture 13, or may be provided on both, and the mounting portions 23 may be configured to be detachably attached to each other.

[0017] A power receiving unit (also referred to as a first power receiving unit) 24 that receives power transmitted from the power transmitting unit 19 by a wireless power supply method is attached to the upper surface of the fixture body 22 of the lighting fixture 13 at a position facing the power transmitting unit 19 of the fixture mounting device 12. The power received by the power receiving unit 24 is supplied to the lighting unit.

[0018] The power receiving section 24 includes a power receiving means for wirelessly receiving power, and a power receiving circuit for converting the power received by the power receiving means into a predetermined power and supplying it to the lighting unit.

[0019] In order to efficiently wirelessly supply power, it is preferable that the power transmitting unit 19 and the power receiving unit 24 are positioned directly opposite each other, and the power transmitting unit 19 and the power receiving unit 24 may face each other with a gap therebetween, or may be in contact with each other. When the power transmitting unit 19 and the power receiving unit 24 face each other with a gap therebetween, even if heat is generated in the power transmitting unit 19 and the power receiving unit 24 during wireless power transmission, the power transmitting unit 19 and the power receiving unit 24 are thermally separated by the gap, so that the mutual thermal influence is suppressed, and an improvement in the heat dissipation effect can be expected. When the power transmitting unit 19 and the power receiving unit 24 are in contact with each other, the power transmitting unit 19 and the power receiving unit 24 are close to each other, so that an improvement in the efficiency of wireless power supply can be expected.

[0020] Next, the installation of the lighting device 10 will be described.

[0021] For example, when wiring for lighting fixtures on the installation surface 11, the fixture mounting devices 12 are attached to, for example, multiple fixture installation locations on the installation surface 11. Alternatively, when renovating, for example, multiple existing lighting fixtures installed on the installation surface 11, the fixture mounting devices 12 are attached to, for example, multiple fixture installation locations from which the existing lighting fixtures were removed. In the fixture mounting device 12 attached to the installation surface 11, a power line is electrically connected to the power transmission unit 19, and the wiring work is completed.

[0022] When installing the lighting fixture 13, the lighting fixture 13 is attached to the fixture mounting surface 18 of the fixture mounting device 12 by the mounting portion 23. By mounting the lighting fixture 13 on the fixture mounting surface 18 of the fixture mounting device 12, the power transmitting unit 19 and the power receiving unit 24 face each other, enabling wireless power supply. When installing this lighting fixture 13, only the installation work of the lighting fixture 13 is required, and no electrical wiring work is required.

[0023] In addition, when power is supplied to the power transmission unit 19 of the fixture mounting device 12, power is transmitted from the power transmission unit 19 and received by the power receiving unit 24 of the lighting fixture 13, and power is supplied from the power receiving unit 24 to the lighting unit, causing the light source to light up.

[0024] Furthermore, when the lighting fixture 13 needs to be removed for maintenance or replacement, the lighting fixture 13 can be removed from the fixture mounting device 12 by removing the mounting portion 23. In this case, only the work of removing the lighting fixture 13 is required, and no work such as disconnecting the electrical wiring is required.

[0025] As described above, by attaching the fixture mounting device 12 to the installation surface 11, when installing, maintaining, or replacing the lighting fixture 13, it is possible to provide a lighting device 10 that can improve the workability of the lighting fixture 13 by simply attaching or removing the lighting fixture 13 to or from the fixture mounting device 12, without the need for wiring work.

[0026] Since the lighting device 10 does not require wiring work for the lighting fixture 13 to be attached to the fixture mounting device 12, the lighting fixture 13 can be attached and detached to the fixture mounting device 12, for example, by an unmanned aerial vehicle, making installation easier and reducing the time required for installation.

[0027] Next, a second embodiment is shown in FIG. 2 and FIG.

[0028] FIG. 2 shows a lighting system 30 including a plurality of lighting devices 10, and FIG.

[0029] In the lighting system 30, when a plurality of lighting fixtures 13 are installed on the installation surface 11, a power line 20 is connected to one or more specific fixture mounting devices 12, and the specific fixture mounting device 12 is configured to supply power to the other fixture mounting devices 12 by wireless power supplying, and the other fixture mounting devices 12 are configured to supply power to still other fixture mounting devices 12 by wireless power supplying. For fixture mounting devices 12 other than the specific fixture mounting device 12, wiring of the power line 20 to the fixture mounting devices 12 is not required.

[0030] The instrument mounting device 12 includes a housing 31 and an instrument main body 16 attached to the lower surface of the housing 31. The instrument mounting device 12 has an installation side mounting surface 17 on the upper surface of the housing 31. The housing 31 is formed to have a quadrangular shape, for example a square, in a plan view.

[0031] The lighting device 10 is provided with at least one of a power transmission module 33 equipped with a second power transmission unit 32 of a wireless power supply type and a power receiving module 35 equipped with a second power receiving unit 34, on the side of the housing unit 31, which is the side of the fixture mounting device 12.

[0032] The lighting device 10 shown on the left side of each of Fig. 2 and Fig. 3 includes a first fixture mounting device 12a on the power transmission side as the fixture mounting device 12. In the first fixture mounting device 12a, a power line 20 is connected to a power transmission unit (hereinafter referred to as a first power transmission unit) 19, and four power transmission modules 33 including second power transmission units 32 are attached to the four side surfaces of a housing unit 31, and the power line 20 is also connected to each of the second power transmission units 32.

[0033] The lighting device 10 shown on the right side of Fig. 2 and Fig. 3 includes, as the fixture mounting device 12, a second fixture mounting device 12b that is the power receiving side relative to a first fixture mounting device 12a that is the power transmitting side. In the second fixture mounting device 12b, the power line 20 is not connected to the first power transmitting unit 19, and a power receiving module 35 including a second power receiving unit 34 is attached to each of two adjacent side surfaces, and a power transmitting module 33 including a second power transmitting unit 32 is attached to each of the remaining two adjacent side surfaces. In this second fixture mounting device 12b, the first power transmitting unit 19, each second power receiving unit 34, and each second power transmitting unit 32 are electrically connected.

[0034] The first instrument mounting device 12a and the second instrument mounting device 12b are installed at a predetermined distance apart so that one of the second power transmitting units 32 of the first instrument mounting device 12a and one of the second power receiving units 34 of the second instrument mounting device 12b face each other, preferably directly opposite each other.

[0035] When power is supplied to the first fixture mounting device 12a through the power line 20, the lighting fixture 13 is turned on by transmitting power from the first power transmission unit 19 to the power receiving unit (first power receiving unit) 24 of the lighting fixture 13 mounted on the first fixture mounting device 12a.

[0036] Furthermore, power is transmitted from the second power transmitting unit 32 of the first fixture mounting device 12a to the second power receiving unit 34 of the opposing second fixture mounting device 12b. In the second fixture mounting device 12b, the power received by the second power receiving unit 34 is supplied to the first power transmitting unit 19, and the power is transmitted from the first power transmitting unit 19 to the power receiving unit (first power receiving unit) 24 of the lighting fixture 13 attached to the second fixture mounting device 12b, thereby lighting the lighting fixture 13.

[0037] The first instrument mounting device 12a also transmits power to another second instrument mounting device 12b facing the second power transmitting units 32 arranged on the four side surfaces.

[0038] The second fixture mounting device 12b transmits the power received at the second power receiving unit 34 from the second power transmitting unit 32 to the second power receiving unit 34 of another second fixture mounting device 12b arranged opposite to the second power transmitting unit 32. Therefore, power is sequentially supplied from the first fixture mounting device 12a to the multiple second fixture mounting devices 12b, and the lighting fixtures 13 arranged in each first fixture mounting device 12a are turned on.

[0039] In addition, the second appliance mounting device 12b has a second power receiving unit 34 on two sides, so it is capable of receiving power from two different directions, and can receive power from either one or both of the two directions, and has a second power transmitting unit 32 on two sides, so it is capable of transmitting power in two different directions, and can transmit power from either one or both of the two directions.

[0040] The second power transmitting unit 32 and the second power receiving unit 34 are detachably attached to the side surfaces of the fixture mounting device 12. In accordance with the installation status of the plurality of lighting devices 10 on the installation surface 11, the second power transmitting unit 32 is attached to a side surface in a direction in which power is transmitted from the fixture mounting device 12 by wireless power supply, and the second power receiving unit 34 is attached to a side surface in a direction in which power is received from another fixture mounting device 12 by wireless power supply. Although an example in which the second power transmitting unit 32 or the second power receiving unit 34 is attached to four side surfaces of the fixture mounting device 12 is shown in Figs. 2 and 3, in accordance with the installation status of the plurality of lighting devices 10 on the installation surface 11, for example, the second power transmitting unit 32 or the second power receiving unit 34 may be attached to only one side surface of the fixture mounting device 12.

[0041] Thus, in the second embodiment, when multiple lighting fixtures 13 are installed on the installation surface 11, by connecting the power line 20 to a specific fixture mounting device 12, power can be supplied from the specific fixture mounting device 12 to the other fixture mounting devices 12 via a wireless power supply method, and there is no need to connect the power line 20 to the other fixture mounting devices 12, thereby providing a lighting system 30 that does not require wiring of the power line 20.

[0042] In addition, since the second power transmission unit 32 and the second power receiving unit 34 are detachable from the side of the fixture mounting device 12, by arranging the second power transmission unit 32 on the side corresponding to the power transmission direction of the fixture mounting device 12 and arranging the second power receiving unit 34 on the side corresponding to the power receiving direction, it is possible to easily adapt to the installation situation of the lighting device 10.

[0043] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
