DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment in which the present invention is embodied in an electric appliance will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of a non-contact power feeding system. In the non-contact power supply system, for example, a lighting fixture 10 as an electric appliance is placed on a table T or a shelf S placed on the floor of a room R, and power is supplied to the lighting fixture 10 in a non-contact manner. It is what is done.
  The luminaire 10 has a light source L or the like as a load portion mounted inside a casing 11 having a hexahedron box-like appearance, and irradiates the irradiation object with the light source L that is mounted. Is.
  As shown in FIGS. 2 to 4, the housing 11 of the lighting fixture 10 of the present embodiment is hollow and has an external appearance in a state in which the open end portions 12 a of the two housing members 12 having a bottomed square tube shape are overlapped with each other. It is comprised so that a substantially box shape may be comprised. In addition, the housing 11 includes a power receiving coil 13, a rotating mechanism 14, a rectifying / smoothing circuit 15, an optical member 16, and a light source L. In addition, the light source L is comprised, for example with an incandescent lamp, LED, organic EL, inorganic EL, etc.
The power receiving coil 13 is fixed to the flat surface portion 21 a of the hemispherical coil support member 21 and is electrically connected to the rectifying and smoothing circuit 15.
A part of the coil support member 21 is formed with two projecting portions 21b constituting the turning mechanism 14 projecting radially outward so as to be opposite to each other in the circumferential direction 180 degrees. The protrusion 21b is fitted into a recess 22b formed in the opening end 22a of the rotation support member 22 having an opening on one surface side that forms a concave shape following the spherical portion of the coil support member 21, and rotates (rotates). Supported as possible.
  The rotation support member 22 has a total of two protrusions 22c constituting the rotation mechanism 14 protruding outward in the radial direction at a position different from the depression 22b by about 90 degrees in the circumferential direction, that is, each protrusion of the rotation support member 22. 22c is formed so as to be 180 degrees opposite in the circumferential direction. Here, each of the housing members 12 is provided with a recess 12b to support the protrusion 22c of the rotation support member 22. For this reason, the protrusion 22c is supported by each housing member 12 so that rotation (turning) is possible by superimposing so that the opening edge part 12a of housing members 12 may contact | abut. In the present embodiment, since the coil support member 21 provided with the power receiving coil 13 is rotated on two axes around the protrusions 21b and 22c, the power receiving coil 13 is also rotated accordingly. It is like that.
Next, the electrical configuration of the luminaire 10 and the non-contact power feeding system including the luminaire 10 will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the table T and the shelf S on which the lighting fixture 10 is placed include a power supply block 31 and a power supply coil 32. As shown in FIG. 2, the power supply block 31 includes a rectifying / smoothing circuit 31a that converts alternating power supplied from the commercial power supply 30 into DC power, and an inverter 31b that converts DC power from the rectifying / smoothing circuit 31a back into alternating power. It has. The inverter 31 b is electrically connected to the power supply coil 32 and supplies an alternating current to the power supply coil 32. For this reason, in the feeding coil 32, an alternating magnetic flux is generated so as to be orthogonal to the inside of the ring of the coil 32.
  The power receiving coil 13 provided in the luminaire 10 is connected to a light source L as a load unit. The light source L receives the alternating magnetic flux of the power feeding coil 32 and the power received by the power receiving coil 13 is generated by the rectifying and smoothing circuit 15. And the light source L emits light.
  As described above, in the luminaire 10 of the present embodiment, the power receiving coil 13 provided inside the housing 11 serving as a container is rotated, so that the power receiving coil 13 may be substantially parallel to the power feeding coil 32. It becomes possible. Thereby, the electric power supplied to the light source L as a load part can be made sufficient, and the lighting fixture 10 can be used with high efficiency. Moreover, since the housing | casing 11 is made into the cube shape which has several planes, as shown in FIG. 6, it becomes possible to arrange | position the lighting fixtures 10 mutually. At this time, by configuring each mounting plate S1 of the shelf S with a light transmitting member, it is possible to irradiate the irradiation target object mounted on the lower mounting plate S1. It has become.
Next, characteristic effects of the present embodiment will be described.
(1) The rotation mechanism 14 including the protrusion 21b of the coil support member 21 that supports the power receiving coil 13 and the protrusion 22c of the rotation support member 22 can rotate the power reception coil 13 around two axes orthogonal to each other. Composed. For this reason, the position of the power receiving coil 13 with respect to the power feeding coil 32 can be adjusted with a higher degree of freedom as compared with a configuration in which it is rotated around one axis. Thus, the positional relationship can be made substantially parallel to the feeding coil 32 by adjusting the angle of the power receiving coil 13.
  (2) Since the housing 11 serving as a container has a cubic shape (box shape), it can be stably placed on the table T, the shelf S, or the like on any plane. For this reason, it can suppress that the receiving coil 13 shakes within the housing | casing 11, and can stabilize the relative positional relationship of the receiving coil 13 and the feed coil 32. FIG. Thereby, it becomes possible to supply electric power to the light source L as a load part more efficiently.
(3) Since the load unit is configured by the light source L as illumination, light can be irradiated to the irradiation object of the light source L.
(4) Since the housing 11 is box-shaped, a plurality of housings 11 (lighting fixtures 10) can be stably stacked and arranged.
In addition, you may change embodiment of this invention as follows.
In the above embodiment, the shape of the housing 11 is a regular hexahedron shape, but is not limited thereto. For example, if it is a shape composed of a plurality of planes such as a rectangular parallelepiped or a shape having at least one plane, it is possible to stably arrange the casing 11 and the lighting fixture 10 on that plane.
  In the above-described embodiment, the hexahedron box is used. However, the present invention is not limited to this, and for example, a substantially spherical shape may be used as shown in FIGS. More specifically, the housing 11 can be formed into a substantially spherical shape by overlapping the open end portions 40 a of the two hemispherical housing members 40. Thus, since the shape of the housing | casing 11 is formed so that it may form substantially spherical shape with the two housing members 40, compared with box shape (cubic shape), the winding number (surface area) of the receiving coil 13 is made the same. However, the size of the casing 11 itself can be suppressed.
  In the above embodiment, although not particularly mentioned, for example, a configuration in which a plurality of power receiving coils 13 are provided inside the housing 11 may be employed. Moreover, as shown in FIG. 5, each coil 13 is preferably configured such that one coil is inclined with respect to the other coil. By configuring each coil 13 so as to form a predetermined angle in this way, it becomes possible to supply suitable power to the light source L as a load unit with any one of the coils 13. Moreover, since it can arrange | position along the magnetic field (magnetic flux) of the electric power feeding coil 32 depending on the angle of each receiving coil 13, electric power can be supplied more efficiently with respect to the light source L as a load part.
-In above-mentioned embodiment, although the rotation mechanism 14 was made the structure which can be rotated around two axes | shafts, it is not restricted to this. For example, a configuration that can rotate around one axis may be employed.
In the above embodiment, the lighting fixture 10 as an electric appliance is placed (arranged) on the shelf S or the table T, but the lighting fixture 10 is placed in a place other than this to receive the coil of the lighting fixture 10. 13 may be configured to be rotatable.
  -In the said embodiment, although the electric appliance was comprised with the lighting fixture 10, it is not limited to this, TV, a photo frame, a small display, a speaker, a fan, the fan for an air conditioning, an air cleaner, an aroma diffuser It may be an electrical appliance such as.
