Abstract

A lighting fixture includes a light source holder, a pair of position adjustors, and an outer shell. The light source holder holds a light source. The position adjustors are arranged to face each other and interpose the light source holder between themselves and supports the light source holder to allow the light source holder to rotate around a first virtual axis defined as a virtual axis passing through the position adjustors. The outer shell has an opening in which the light source holder and the position adjustors are arranged and supports the position adjustors to allow the position adjustors to rotate around a second virtual axis defined by a normal to an opening plane of the opening. The first virtual axis intersects with the second virtual axis and is located either within or behind the opening plane.

First claim

The invention claimed is:

1. A lighting fixture, comprising:
a light source holder configured to hold a light source;
a pair of position adjustors arranged to face each other and interpose the light source holder between the position adjustors themselves, the pair of position adjustors supporting the light source holder thereon to allow the light source holder to rotate around a first virtual axis, the first virtual axis being defined as a virtual axis that passes through the pair of position adjustors; and
an outer shell having an opening in which the light source holder and the pair of position adjustors are arranged and supporting the pair of position adjustors to allow the pair of position adjustors to rotate around a second virtual axis, the second virtual axis being defined by a normal to an opening plane of the opening,
the first virtual axis intersecting with the second virtual axis and being located either within or behind the opening plane,
wherein each of the pair of position adjustors is arranged to have one end surface thereof, aligned with a direction of rotation around the second virtual axis, at least part at the one end surface located forward of a part close to the one end surface relative to the first virtual axis, of a front surface of the light source holder in a situation where the light source holder has rotated around the first virtual axis, and
wherein the light source holder comprises a pair of facing parts, at least part of each of the pair of facing parts facing an either one of the pair of position adjustors along a virtual axis perpendicular to both the first virtual axis and the second virtual axis, in a plan view from a direction of the second virtual axis, in at least one of a state in which the light source holder does not rotate about the first virtual axis and a state in which the light source holder rotates about the first virtual axis.

2. The lighting fixture of claim 1 ,
wherein the outer shell includes
a housing portion arranged to house the light source holder and the pair of position adjustors and coupled to the opening; and
a guide portion provided on an inner peripheral surface of the housing portion and along a circumference of the inner peripheral surface,
wherein each of the pair of position adjustors includes a hook to be caught in the guide portion, and
wherein the light source holder is caused to rotate around the second virtual axis by moving the respective hooks of the pair of position adjustors along the guide portion.

3. The lighting fixture of claim 1 ,
wherein the light source holder has a pair of recesses, into which the pair of position adjustors are respectively fitted, on both side portions thereof in a direction aligned with the first virtual axis.

4. A lighting fixture, comprising:
a light source holder configured to hold a light source;
a pair of position adjustors arranged to face each other and interpose the light source holder between the position adjustors themselves, the pair of position adjustors supporting the light source holder thereon to allow the light source holder to rotate around a first virtual axis, the first virtual axis being defined as a virtual axis that passes through the pair of position adjustors; and
an outer shell having an opening in which the light source holder and the pair of position adjustors are arranged and supporting the pair of position adjustors to allow the pair of position adjustors to rotate around a second virtual axis, the second virtual axis being defined by a normal to an opening plane of the opening,
the first virtual axis intersecting with the second virtual axis and being located either within or behind the opening plane,
wherein the light source holder has an outer peripheral side surface located on an outer periphery of a front surface of the light source holder, and
the outer peripheral side surface has a lighting window to allow light emitted from the light source to emerge out of the light source holder.

5. The lighting fixture of claim 4 ,
wherein the lighting window is retracted into the outer shell when the front surface of the light source holder is parallel to the opening plane.

6. The lighting fixture of claim 4 , further comprising:
a first detector configured to detect a position of rotation of the light source holder around the first virtual axis,
wherein the light source is configured to be turned ON and OFF depending on a result of detection by the first detector.

7. The lighting fixture of claim 6 ,
wherein the first detector includes a mechanical switch configured to turn ON and OFF according to the position of rotation of the light source holder around the first virtual axis.

8. The lighting fixture of claim 6 ,
wherein the first detector includes a contactless sensor configured to detect the position of rotation of the light source holder contactlessly around the first virtual axis.

9. The lighting fixture of claim 4 , further comprising:
a detector configured to detect a position of rotation of the light source holder around the second virtual axis,
wherein the light source is configured to change a light color thereof according to a result of detection by the detector.
