  In addition, the slide body 420 is provided with a wire connector 440 that is a long metal plate that curves so as to surround the illumination member 100. The wire connector 440 is, for example, a long stainless steel plate, but is not limited thereto. The wire connection body 440 is fixed to the slide body 420 with screws 431. As a result, the wire connector 440 also moves in accordance with the movement of the slide body 420.

  One upper end portion of the pair of hanging members 300 is attached to one end portion in the longitudinal direction of the wire connector 440. Further, the other upper end portion of the pair of hanging members 300 is attached to the other end portion in the longitudinal direction of the wire connector 440. Thereby, the suspension member 300 also moves in accordance with the movement of the slide body 420. That is, the decorative member 200 suspended from the suspension member 300 also moves in accordance with the movement of the slide body 420.

  As shown in FIG. 6, the holding body 410 is provided with a bent portion 414 for preventing the illumination member 100 from falling off the holding body 410. The bent portion 414 is formed by bending a part of the metal wire constituting the holding body 410 toward the top of the globe 130 of the lighting member 100.

  In the present embodiment, the bent portion 414 is a portion where the open ends of one metal wire constituting the holding body 410 are connected to each other. For this reason, the metal wire in the bent portion 414 is inserted into the metal pipe 450. That is, the open ends of the metal wires in the bent portion 414 are arranged so as to face each other in the metal pipe 450.

  Further, the metal pipe 450 is held by a stopper 460. The stopper 460 is a resin part made of resin, and holds the metal pipe 450 into which the metal wire of the bent portion 414 is inserted. The stopper 460 contacts the vicinity of the top of the globe 130 of the lighting member 100 when the rotating member 400 is attached to the lighting member 100. When the stopper 460 comes into contact with the globe 130, the illumination member 100 can be prevented from falling off the holding body 410.

  The rotating member 400 configured in this way is attached to the illumination member 100 as shown in FIG. For example, by pushing the lighting member 100 toward the holding body 410 of the rotating member 400 from the state shown in FIG. 5, as shown in FIG. It can be held by the second holding part 412.

  Then, as shown in FIG. 8B, in the rotating member 400, the slide main body 420 can be slid along the rail portion 413 of the holding body 410. That is, the slide body 420 slides along the optical axis of the illumination member 100.

  Accordingly, as shown in FIG. 9A, when the illumination member 100 held by the rotating member 400 is attached to the socket 2 c, the lighting member 100 is suspended by the suspension member 300 connected to the rotating member 400. When the horizontal position of the decorative member 200 is shifted with respect to the instrument main body 2, the horizontal position of the decorative member 200 is obtained by sliding the slide main body 420 as shown in FIG. 9B. Misalignment can be eliminated.

  Specifically, by sliding the slide main body 420 along the rail portion 413 of the holding body 410, the pair of suspension members 300 connected to the wire connection body 440 of the slide main body 420 moves, and accordingly Thus, the decorative member 200 (decorative panel 210) suspended from the suspension member 300 moves in the horizontal direction. That is, in conjunction with the slide movement of the slide body 420, the decorative member 200 (decorative panel 210) slides in the horizontal direction along the ceiling surface (horizontal plane). Thereby, the horizontal position of the decorative member 200 (decorative panel 210) can be adjusted.

  In the present embodiment, since the slide body 420 is operated by inserting a hand from the opening of the decorative panel 210, the transparent cover 220 of the decorative member 200 is removed when the slide main body 420 is slid. .

[Lighting unit installation procedure]
Next, a procedure for attaching the illumination unit 3 to the fixture body 2 will be described with reference to FIGS. 10A to 10D. FIG. 10A is a diagram illustrating a state in which an existing lamp is removed from the instrument body 2. FIG. 10B is a diagram illustrating a state when the illumination unit 3 according to the embodiment is attached to the instrument body 2. FIG. 10C is a diagram illustrating a state when the position of the decorative panel 210 is adjusted. FIG. 10D is a diagram showing a state when the translucent cover 220 is attached to the decorative panel 210.

  As shown in FIG. 10A, the existing LED bulb 100A attached to the socket 2c of the instrument body 2 is removed from the socket 2c.

  Next, as shown in FIG. 10B, the illumination member 100 of the illumination unit 3 is attached to the socket 2 c of the instrument body 2. Specifically, the rotating member 400 connected to the decorative panel 210 by the hanging member 300 is attached to the lighting member 100, and the lighting member 100 is lifted and attached to the socket 2c in this state. At this time, by removing the translucent cover 220 from the decorative panel 210 in advance, the user can insert the hand into the opening of the decorative panel 210 and grasp the lighting member 100 by hand. Accordingly, the base 110 can be screwed into the socket 2c by inserting the hand from the opening of the decorative panel 210 and holding the lighting member 100 to lift the lighting member 100 and rotate the lighting member 100.

  When the illumination member 100 is rotated and screwed into the socket 2c, the illumination member 100 is rotatably held by the rotation member 400. Therefore, only the illumination member 100 is rotated without rotating the rotation member 400. It can be attached to the socket 2c. That is, the illumination member 100 can be attached to the socket 2c without the decoration member 200 (decoration panel 210) suspended from the rotation member 400 being accompanied by the illumination member 100.

  Thus, when the illumination member 100 is attached to the socket 2c of the instrument main body 2, as shown in FIG. 10C, the decorative panel 210 is suspended by the suspension member 300 and the opening 2a of the instrument main body 2 is opened. It is arranged so that it surrounds. At this time, as shown in FIG. 1 described above, since the lighting member 100 is pulled up so that the decorative panel 210 suspended by the suspension member 300 is hooked on the ceiling 4, the coil spring housed in the storage case 230 is suspended. It will be stretched by being pulled by the lower member 300. As a result, the decorative panel 210 is urged and held toward the ceiling surface by the spring elastic force (spring restoring force) of the coil spring 233. In this manner, the length of the suspension member 300 from the rotating member 400 to the decorative panel 210 is automatically adjusted by extending the coil spring 233.

  Here, when the horizontal position of the decorative panel 210 is shifted with respect to the instrument body 2 as shown in FIG. 9A, the position adjustment by the rotating member 400 is performed as shown in FIG. 10C. By the mechanism, the decorative panel 210 can be horizontally moved so that the horizontal displacement of the decorative panel 210 is eliminated.

  Specifically, as shown in FIG. 10C, the sliding member 420 (position adjusting mechanism) of the rotating member 400 is slid to move the suspension member 300 as shown in FIG. The decorative panel 210 suspended from the suspension member 300 moves as it moves. Thereby, the horizontal position of the decorative panel 210 can be adjusted, and the horizontal position shift of the decorative panel 210 can be eliminated. That is, the central axis of the lighting fixture 1 and the central axis of the decorative panel 200 can be matched.

  Next, as shown in FIG. 10D, the translucent cover 220 is attached to the decorative panel 210. Thereby, the decoration member 200 is arrange | positioned so that the opening part 2a of the instrument main body 2 may be covered (refer FIG. 1), and the instrument main body 2 is decorated with the decoration member 200. FIG. In this way, the design of the lighting fixture 1 can be changed.

[Effects]
Next, the effect of the lighting fixture 1 in this Embodiment is demonstrated including the process which came to the one aspect | mode of this invention.

  When the user wants to change the design of the lighting fixture after installing the lighting fixture on the ceiling or the like, the user needs to ask the construction contractor to replace the lighting fixture.

  Therefore, a rotating member that is rotatably attached to an illumination member (such as an LED bulb) that is mounted on the socket of the instrument body, and a decorative member that is suspended from the rotating member by a hanging wire (suspending member). It has been studied to change the design of a lighting fixture by using a lighting unit consisting of:

  However, in a lighting fixture in which a lighting member such as an LED bulb is attached to the socket in a lateral orientation like the fixture main body 2 in the present embodiment, the depth of the fixture main body or the light source of the lighting member in the fixture main body Since the center varies depending on the model of the instrument body and the matching of the lighting member to be attached, there is a problem that it is difficult to cope with the above lighting unit.

  In particular, since the position of the illumination member (light source) in the insertion direction of the instrument body into the socket varies depending on the model of the instrument body and the illumination member, the decorative member suspended from the rotating member is displaced in the horizontal direction. There is. As a result, for example, the center of the decorative member and the center of the instrument body are shifted.

  Therefore, in the lighting fixture 1 and the lighting unit 3 in the present embodiment, the decorative member 200 arranged on the ceiling surface side so as to close the opening hole 4a of the ceiling 4 and the horizontal position of the decorative member 200 can be adjusted. A rotation member 400 having a position adjusting mechanism that is attached to the illumination member 100 so as to be rotatable with respect to the illumination member 100, and the decorative member 200 and the rotation member 400 are connected to each other and from the rotation member 400 A hanging member 300 for hanging the decorative member 200 is provided.

  Thereby, even if it is the instrument main body 2 to which the illuminating member 100 is attached with a horizontal attitude | position, the decoration member 200 can be arrange | positioned in the predetermined position of a ceiling surface.

  Specifically, the opening 2c of the instrument body 2 is covered by the decorative member 200 suspended from the rotation member 400 attached to the illumination member 100 by the suspension member 300. Thereby, the instrument body 2 is decorated by the decorative member 200. Therefore, by performing a relatively simple operation of attaching the lighting member 100 to the fixture body 2, the design of the lighting fixture 1 can be easily changed without performing a construction for replacing the fixture body 2.

  Moreover, since the decorative member 200 is suspended from the rotating member 400 attached to the lighting member 100 in a state of being rotatable with respect to the lighting member 100, when the lighting member 100 is attached to the instrument body 2, The lighting member 100 can be screwed into the socket 2c without the decorative member 200 suspended from the rotating member 400 rotating with the lighting member 100 due to the rotation of the lighting member 100.

  Furthermore, since the rotation member 400 has a position adjustment mechanism that enables the horizontal position of the decorative member 200 to be adjusted, the horizontal position of the decorative member 200 suspended from the illumination member 100 is finely adjusted. Thus, the horizontal displacement of the decorative member 200 can be eliminated. Specifically, the center of the decorative member 200 and the center of the instrument body 2 can be easily matched.

  As mentioned above, according to the lighting fixture 1 and the lighting unit 3 in this Embodiment, a design can be easily changed with respect to a wide variety of lighting fixtures.

  In the lighting fixture 1 and the lighting unit 3 according to the present embodiment, the rotating member 400 holds the lighting member 100 so that the lighting member 100 can be rotated about the optical axis of the lighting member 100 as a rotation axis. 410 and a slide main body 420 attached to the holding body 410 so as to be slidable in the optical axis direction of the illumination member 100 as a position adjusting mechanism.

  Thereby, the decorative member 200 suspended from the rotating member 400 can be moved in the horizontal direction by sliding the slide body 420 attached to the holding body 410. Therefore, the horizontal displacement of the decorative member 200 can be eliminated with a simple operation.

  In the lighting fixture 1 and the lighting unit 3 according to the present embodiment, the holding body 410 is a metal frame made of a single metal wire, and each holds the lighting member 100 by surrounding the outer periphery of the lighting member 100. Two rails that connect the substantially arc-shaped arc ends of the first holding part 411 and the second holding part 412 and the substantially arc-shaped arc ends of the first holding part 411 and the second holding part 412 that extend in parallel. Further, the slide body 420 is held by the two rail portions 413 so as to be slidable relative to the two rail portions 413.

  Thereby, the slide main body 420 can be easily slid. Moreover, since the part which shields the illuminating member 100 can be reduced as much as possible by making the holding | maintenance body 410 the metal frame which consists of metal wires, the fall of the light beam as the lighting fixture 1 can also be suppressed.

  Moreover, in the lighting fixture 1 and the lighting unit 3 in the present embodiment, the slide main body 420 has a resin-made first slide body 421 having an insertion hole through which two metal wires forming the two rail portions 413 are inserted. And a metal second slide body 422 that sandwiches the first slide body 421.

  Thus, by making the first slide body 421 that slides with the metal wire made of resin, it is possible to achieve both the improvement of the slide performance of the slide body 420 and the improvement of the holding force due to the friction of the slide body 420. That is, it is possible to easily slide the slide body 420 while maintaining the holding force of the slide body 420 to the holding body 410.

  In addition, by sandwiching the first slide body 421 with the metal second slide body 422, the rigidity of the slide body 420 can be increased as compared with the case where the slide body 420 is configured only with resin. Thereby, even if the decorative member 200 is suspended through the slide main body 420, it is possible to suppress problems such as dropping of the decorative member 200 due to deterioration of the slide main body 420.

  Moreover, in the lighting fixture 1 and the lighting unit 3 in the present embodiment, the suspension member 300 is a pair of wires, and the slide body 420 is a long metal plate that curves so as to surround the lighting member 100. A wire connector 440 is provided. One of the pair of wires of the hanging member 300 is attached to one end of the wire connecting body 440 in the longitudinal direction, and the other of the pair of wires of the hanging member 300 is attached in the longitudinal direction of the wire connecting body 440. It is attached to the other end.

  Thereby, the decoration member 200 can be stably suspended by the pair of suspension members 300 (wires).

  Moreover, in the lighting fixture 1 and the lighting unit 3 in the present embodiment, the decorative member 200 is detachably attached to the decorative panel 210 surrounding the opening hole 4a of the ceiling 4 and the decorative panel 210, and the opening hole 4a of the ceiling 4 And a translucent cover 220 covering the.

  Thereby, the design of the lighting fixture 1 can be changed by replacing the decorative panel 210 with another type of decorative panel 210 or by replacing the translucent cover 220 with another type of translucent cover 220 as a decorative cover or the like. It can be easily changed.

  Moreover, in the lighting fixture 1 and the lighting unit 3 in the present embodiment, the lighting member 100 is a lamp having a T-shaped globe.

  Thereby, even if it is a case where the illuminating member 100 is attached to the socket 2c in the horizontal orientation, the illuminating member 100 can be attached to the socket 2c in advance.
