An accommodating portion 10 that accommodates the spherical body 5 of the illumination main body 1 is fixed to the end of the base portion 2 opposite to the contact portion 2b.

  The accommodating portion 10 includes a spherical body 11, a pair of projecting portions 12 projecting on both sides thereof, and a cylindrical portion 13 projecting from one annular plane of the spherical body 11. The spherical body 11 has a shape obtained by cutting the sphere with a pair of parallel planes. That is, the spherical body 11 is a hollow spherical body having a pair of parallel annular planes 14 and 15, and has a spherical inner surface that accommodates the spherical outer surface 8 of the spherical body 5 of the illumination main body 1. A protrusion insertion hole 17 is formed in the wall portion. The protrusion insertion hole 17 is a long hole extending in a slender shape parallel to the irradiation surface 3a of the illuminating unit 3, and both ends thereof are formed in an arc shape.

  As shown in FIG. 2, the housing portion 10 is formed of a pair of half members 10 </ b> A and 10 </ b> B that bisect the housing portion 10. However, the cylindrical part 13 is provided in one half member 10A. The spherical inner surface that accommodates the spherical outer surface 8 of the spherical body 5 of the illumination main body 1 is formed by the spherical inner surfaces 16A and 16B of the pair of half members 10A and 10B. Therefore, the accommodating portion 10 is disposed so that the pair of half-members 10A and 10B covers the spherical body 5 of the illumination main body 1 and is mounted in the fastener insertion holes 18 formed in the pair of overhang portions 12. It is configured by being fastened by a fastener 19. At this time, the protrusion 9 of the spherical body 5 of the illumination main body 1 is inserted and disposed in the protrusion insertion hole 17 of the spherical body 11 of the housing portion 10.

  In this way, the spherical body 5 of the illumination main body 1 is accommodated in the spherical body 11 of the accommodating portion 10 fixed to the base portion 2, and the spherical body 5 of the illumination main body 1 and the accommodating portion 10 that accommodates the spherical body 5 are accommodated. A ball joint is constituted by the spherical body 11.

  The base portion 2 is inserted into the outer surface of the cylindrical portion 13 of the accommodating portion 10 and is fixed to the cylindrical portion 13.

  The LED light source in the illumination unit 3 is electrically connected to the base unit 2 by a circuit board and lead wires arranged in the illumination main body unit 1 and the base unit 2, and is configured to supply power to the LED light source. ing.

  Hereinafter, a case where the lighting device of the present invention is mounted on a socket provided on a ceiling portion of a room will be described.

  The base part 2 of the lighting device is inserted into the socket, and the main body part 1 is rotated to attach the base part 2 to the socket. At this time, when the illumination main body 1 is rotated, the projection 9 of the spherical body 5 of the illumination main body 1 is engaged with the edge of the projection insertion hole 17 of the spherical body 11 of the housing 10 fixed to the base 2. Therefore, the base part 2 is rotated together with the rotation of the illumination main body part 1. Thereby, the nozzle | cap | die part 2 can be mounted | worn with a socket.

  After the lighting device is mounted on the socket, the posture of the irradiation surface 3 a of the lighting unit 3 can be adjusted by adjusting the posture of the lighting main body 1. That is, since the ball joint is constituted by the spherical body 5 of the illumination main body 1 and the spherical body 11 of the accommodating portion 10 that accommodates it, the angle (tilt) of the illumination main body 1 is adjusted to adjust the illumination section 3. The irradiation surface 3a can be in a horizontal posture, for example. Further, since the projection insertion hole 17 into which the projection 9 of the spherical body 5 of the illumination main body 1 is inserted is formed as a long hole, the illumination main body 1 is rotated in a horizontal plane, for example, each side of the illumination unit 3 is It can be adjusted to be parallel to the wall surface in the room.

  In addition, in the said embodiment, although the spherical body 5 was provided in the illumination main-body part 1 side and the accommodating part 10 which accommodates the spherical body 5 and comprises a ball joint was provided in the nozzle | cap | die part 2 side, it is set as the reverse structure. You can also. That is, a spherical body may be provided on the base part side, and a housing part that houses the spherical body and constitutes a ball joint may be provided on the illumination main body part side. An illumination device having an illumination main body having a light source for illumination, and a base portion attachable to a socket, the spherical body having a spherical outer surface fixed to the base portion, and the illumination main body portion A receiving portion that is provided on the back side opposite to the irradiation surface and that accommodates the spherical body, the spherical body is accommodated in the accommodating portion to form a ball joint, and a protrusion protruding from the outer surface of the spherical body It is inserted into a protrusion insertion hole formed in the housing part.

  Hereinafter, the case where the lighting device of the present invention configured as described above is mounted on a socket provided in a ceiling portion of a room will be described.

  The base part of the lighting device is inserted into the socket, and the main body part is rotated to attach the base part to the socket. At this time, when the illumination body part is rotated, the edge of the projection insertion hole formed in the housing part on the illumination body part side engages with the projection protruding from the outer surface of the spherical body on the base part side. The base part is rotated together with the rotation of the illumination main body part. Thereby, a nozzle | cap | die part can be mounted | worn with a socket.

  After the lighting device is mounted on the socket, the posture of the irradiation surface of the lighting unit can be adjusted by adjusting the posture of the lighting main body. That is, since the ball joint is constituted by the spherical body on the base part side and the housing part on the illumination main body side that accommodates the spherical body, the angle (tilt) of the illumination main body part is adjusted to adjust the irradiation surface of the illumination part. For example, it can be in a horizontal posture. Similarly to the above embodiment, if the projection insertion hole into which the spherical projection on the base part side is inserted is a long hole, the illumination main body is rotated in a horizontal plane, for example, an illumination formed in a square shape. Each side of the section can be adjusted to be parallel to the wall surface in the room.

  Note that the spherical body described above does not have to be a perfect sphere as shown in the above-described embodiment, and may have a spherical outer surface. Of course, a perfect sphere may be sufficient. Moreover, the accommodating part should just accommodate the spherical body and have the inner surface which comprises a ball joint.

  FIG. 3 shows another embodiment of the present invention. This embodiment is different from the embodiment shown in FIGS. 1 and 2 in the shape of the illumination unit 3 and the shape of the protrusion insertion hole 17 formed in the spherical body 11 of the housing unit 10.

  In the present embodiment, the illumination unit 3 has a circular shape, and the protrusion insertion hole 17 is formed in a circular hole. Other configurations are the same as those of the above-described embodiment described with reference to FIGS.

  The case where the lighting device of the present embodiment is mounted on the socket is the same as the above-described embodiment described with reference to FIGS. 1 and 2. However, in this embodiment, since the illumination part 3 is circular shape, it is not necessary to rotate the illumination main-body part 1 within a horizontal surface, and to adjust the direction.
