[0016] [Embodiment of lighting fixture 100] Hereinafter, with reference to the above drawings, a lighting fixture 100 (see FIG. 1), a tool 200 for the lighting fixture 100 (see FIG. 7), and a set of the lighting fixture 100 and the tool 200 according to an embodiment of the present invention will be described. However, the present invention is not limited to the following embodiment, and can be embodied in various aspects without departing from the gist of the present invention. Note that where explanations overlap, they may be omitted as appropriate. Also, in the drawings, the same or equivalent parts are given the same reference symbols, and explanations are omitted or simplified.

[0017] As shown in Figs. 1 and 2, the lighting fixture 100 is, for example, a universal downlight. The universal downlight is a lighting fixture that can change the direction and angle of illumination light. The universal downlight is recessed into a mounting surface. The mounting surface is a wall surface or a ceiling. In the following, unless otherwise specified, the term "lighting fixture 100" refers to the lighting fixture 100 in a state where it is mounted on a mounting surface.

[0018] In detail, the lighting fixture 100 includes a light body U1 and a rotation mechanism U2.

[0019] The lamp U1 includes an exterior body 1, a light source unit 2, a reflecting member 3, and a heat dissipation unit 4. Fig. 1 shows the exterior body 1 and the heat dissipation unit 4. Fig. 2 shows the light source unit 2 and the reflecting member 3.

[0020] 1 and 2, the exterior body 1 is a cylindrical body and houses a light source unit 2 and a reflecting member 3. A heat dissipation unit 4 is attached to the exterior body 1. In detail, the exterior body 1 extends in the optical axis direction D10 (see FIG. 2) from an end face 41 of the heat dissipation unit 4 in the optical axis direction D10.

[0021] In FIG. 2, the light source unit 2 emits illumination light. The light source unit 2 is attached to an end surface 41. An optical axis direction D10 is a direction in which the light emitting surface of the light source 22 faces among directions intersecting the light emitting surface of the light source 22. In the embodiment, "intersection" includes lines, surfaces, or a line and a surface intersecting at right angles, and intersecting at a non-right angle within a range of slight differences (such as tolerances and errors). The optical axis of the illumination light is given the reference symbol "Ax10".

[0022] The light source unit 2 includes a substrate 21, a light source 22, a support unit 23, and a cover 24.

[0023] The light source 22 is mounted on a first surface of the substrate 21. Illumination light is emitted from a light emitting surface of the light source 22. The light source 22 is, for example, a light emitting element array. The light emitting surface of each light emitting element may be covered with a phosphor.

[0024] A second surface of the substrate 21 opposite to the first surface is in thermal contact with the end surface 41. Therefore, heat generated in the light source unit 2 is dissipated by the heat dissipation unit 4.

[0025] The support portion 23 protrudes in the optical axis direction D10 from a peripheral portion of the substrate 21 at the end surface 41. The support portion 23 opens toward the optical axis direction D10 at a position away from the substrate 21 in the optical axis direction D10. Illumination light emitted from the light source 22 passes through the opening of the support portion 23.

[0026] The cover 24 is made of a light-transmitting material such as glass. The cover 24 is attached to the support part 23 at a position away from the light source 22 in the optical axis direction D10. The cover 24 extends in a direction D11 intersecting the optical axis direction D10 (hereinafter referred to as the "intersecting direction"). The cover 24 transmits illumination light that has passed through an opening of the support part 23.

[0027] The heat dissipation part 4 is made of a metal material with high thermal conductivity. An example of this type of metal material is aluminum. As shown in Figures 1 and 2, the heat dissipation part 4 has a plurality of fins 42. The plurality of fins 42 dissipate heat generated within the lamp body U1.

[0028] As shown in FIG. 2, the reflecting member 3 is supported by the exterior body 1. The reflecting member 3 is located inside the exterior body 1 on the optical axis direction D10 side of the cover 24. The reflecting member 3 has a truncated cone shape with both ends in the optical axis direction D10 open. The inner peripheral surface of the reflecting member 3 expands in the cross direction D11 as it moves away from the cover 24 in the optical axis direction D10. The inner peripheral surface is coated with a reflective coating. In the reflecting member 3, the light transmitted through the cover 24 propagates in the optical axis direction D10 without being reflected within the reflecting member 3, or propagates in the optical axis direction D10 while being reflected by the inner peripheral surface of the reflecting member 3. The reflecting member 3 is made of a metal material or a resin material.

[0029] 1 and 2, the rotation mechanism U2 includes a support 51, a support 52, and an attachment spring 53. The supports 51 and 52 are examples of the "first support" and the "second support" of the present invention.

[0030] The support 52 is located in the optical axis direction D10 (i.e., lower on the paper surface of FIG. 2) than the reflecting member 3. The support 52 is a cylindrical body. The axis of the cylindrical body is given the reference symbol "Ax20". The axis Ax20 is an example of the "second axis" in the present invention. Hereinafter, the direction along the axis Ax20 will be referred to as the axial direction D20. In particular, the direction of the axial direction D20 that approaches the reflecting member 3 will be referred to as the approach direction D21. Meanwhile, the direction of the axial direction D20 that moves away from the reflecting member 3 will be referred to as the receding direction D22.

[0031] The support 52 supports the support 51 rotatably in a circumferential direction D23 about the axis Ax20. In the embodiment, the support 52 rotatably supports the support 51 near an end face 521. The end face 521 is a surface located at an end of the support 52 on the approach direction D21 side. The end face 521 has an annular shape and is a surface that expands in a cross direction D24 that crosses the axial direction D20. The end face 521 faces the approach direction D21.

[0032] As shown in FIG. 3, the support 52 has, in addition to an end surface 521, inner circumferential surfaces 522 and 523 and a flat surface 524.

[0033] The inner circumferential surface 522 is located between the inner edge of the end surface 521 and a position slightly separated from the inner edge in the separation direction D22. The inner circumferential surface 522 has a generally cylindrical shape with both ends in the axial direction D20 being open.

[0034] The inner circumferential surface 523 is located closer to the separation direction D22 than the inner circumferential surface 522. The inner circumferential surface 523 has a generally cylindrical shape with both ends in the axial direction D20 open. Therefore, both ends in the axial direction D20 of the support body 52 are open. Each of the inner circumferential surfaces 522, 523 shares the axis Ax20.

[0035] The flat surface 524 connects an end of the inner circumferential surface 522 on the separating direction D22 side and an end of the inner circumferential surface 523 on the approaching direction D21 side. The flat surface 524 is an annular surface extending in the intersecting direction D24 and is approximately parallel to the end surface 521. The flat surface 524 faces the approaching direction D21.

[0036] As shown in Fig. 1 and Fig. 2, the support 51 supports the light source 22 rotatably in the circumferential direction D31 of the axis Ax30. That is, the support 51 supports the lamp body U1 rotatably in the circumferential direction D31. Therefore, when the lamp body U1 is rotated in the circumferential direction D31 and tilted with respect to the rotation mechanism U2, the position of the light source 22 changes along the circumferential direction D31. The axis Ax30 is an example of the "first axis" in the present invention. In the embodiment, the support body 51 is located in the approach direction D21 further than the flat surface 524 of the support body 52 (see Fig. 2).

[0037] 4, support body 51 includes an annular portion 511, a shielding portion 512, and a plurality of protrusions 513. That is, lighting device 100 includes a plurality of protrusions 513. Protrusion 513 is an example of a "first protrusion" according to the present invention.

[0038] The annular portion 511 has a generally annular shape. The inner diameter of the annular portion 511 is smaller than the diameter of the inner peripheral surface 523 (see FIG. 3). The outer diameter of the annular portion 511 is larger than the diameter of the inner peripheral surface 523. Furthermore, the outer diameter is approximately the same as or slightly smaller than the diameter of the inner peripheral surface 522.

[0039] As shown in Fig. 5, the annular portion 511 abuts against the flat surface 524 of the support 52 from the approach direction D21 side, and is fitted inside the inner circumferential surface 522. In this state, the stopper 54 further provided in the rotation mechanism U2 is fixed to the end surface 521 so that the annular portion 511 does not fall off from the support 52. As a result, the support 52 supports the annular portion 511, i.e., the support 51, so as to be rotatable in the circumferential direction D23. In detail, the support 52 supports at least a part of the support 51 and each protrusion 513 inside the support 52 so as to be rotatable in the circumferential direction D23 of the axis Ax20. Note that Fig. 5 does not show the lamp U1.

[0040] 5, the shielding portion 512 is a plate-like member extending in the circumferential direction D23. The shielding portion 512 is formed in a portion of the annular portion 511 that is more inward than the stopper 54. The shielding portion 512 is formed in the annular portion 511 within an angular range of 180° or less in the circumferential direction D23. From such a position, the shielding portion 512 protrudes from the annular portion 511 in the approach direction D21.

[0041] 4 and 5, the shielding portion 512 has two protruding portions 514. The protruding portions 514 protrude in the circumferential direction D23, one at a time, from both ends of the shielding portion 512 in the circumferential direction D23. A through hole 515 is formed in each of the protruding portions 514. The two through holes 515 face each other in the intersecting direction D24. The two through holes 515 share an axis Ax30 (see FIG. 4). The axis Ax30 connects the centers of the two through holes 515.

[0042] Each of the multiple protrusions 513 protrudes from the support body 51. In detail, each of the multiple protrusions 513 protrudes from the annular portion 511 of the support body 51 in the opposite direction to the shielding portion 512 in the axial direction D20 (i.e., the separation direction D22). Each of the multiple protrusions 513 is located apart from one another on the annular portion 511 in the circumferential direction D23.

[0043] As shown in FIG. 6, the exterior body 1 is fastened to the support 51. As a result, the exterior body 1, i.e., the light source 22 (see FIG. 2), is supported by the support 51 so as to be rotatable in the circumferential direction D31. In detail, the exterior body 1 has two flat surfaces 11 near the end of the optical axis direction D10. The two flat surfaces 11 are located apart from each other in the intersecting direction D11. The distance between the two flat surfaces 11 in the intersecting direction D11 is slightly smaller than the distance between the two protruding portions 514 in the intersecting direction D24. One screw hole 12 is formed in each flat surface 11. The two screw holes 12 extend along the intersecting direction D24.

[0044] With the two screw holes 12 aligned with the two through holes 515 inside the two through holes 515, the two screws 13 are fastened into the two screw holes 12 through the two through holes 515. In this way, the exterior body 1 is supported by the support body 51 so as to be rotatable in the circumferential direction D31.

[0045] As shown in FIG. 2 and FIG. 3, the rotation mechanism U2 further includes a reflecting member 55. The reflecting member 55 is housed in an inner circumferential surface 523 of the support 52 so as to be detachable from the support 52. Specifically, spaces for attaching three mounting springs 525 are formed in three locations on the inner circumferential surface 523 of the support 52. One mounting spring 525 is disposed in each space. More specifically, the three mounting springs 525 are disposed at equal angular intervals along the circumferential direction D23. Each mounting spring 525 is fixed to the support 52 by a screw 526. Note that in FIG. 3, only one screw 526 is visible due to the viewing direction.

[0046] The reflecting member 55 has a truncated cone shape with both ends in the axial direction D20 open. The inner peripheral surface of the reflecting member 55 expands in the cross direction D24 as it moves away from the end face 521 in the separation direction D22. The inner peripheral surface is preferably coated with a reflective coating. In the reflecting member 55, the light emitted from the lamp U1 propagates in the separation direction D22 without being reflected in the reflecting member 55, or propagates in the separation direction D22 while being reflected by the inner peripheral surface of the reflecting member 55. In the embodiment, the reflecting member 55 is made of a resin material. However, the present invention is not limited to this, and the reflecting member 55 may be made of a metal material.

[0047] When removing the reflective member 55 from the support 52, the worker inserts his / her finger into the inside of the inner circumferential surface of the reflective member 55 from the end of the reflective member 55 in the receding direction D22. Then, the worker hooks his / her finger on the end of the reflective member 55 in the approaching direction D21 and applies a force in the receding direction D22 to the reflective member 55. As a result, the reflective member 55 is pulled out of the support 52 with the finger and removed from the mounting spring 525. That is, the reflective member 55 is removed from the support 52.

[0048] Conversely, when attaching the reflective member 55 to the support 52, the worker inserts the reflective member 55 into the inner circumferential surface 523. Before the insertion, it may be necessary to align the phase of the reflective member 55 with the inner circumferential surface 523. Thereafter, the worker applies a force to the reflective member 55 in the approach direction D21. As a result, the reflective member 55 engages with the attachment spring 525 and is attached to the support 52.

[0049] [Embodiment of Tool 200] Furthermore, when changing the direction and angle of the illumination light from the lighting fixture 100 (i.e., the irradiation location), it is necessary to rotate the lamp body U1 relative to the rotation mechanism U2 with the reflecting member 55 removed from the support body 52. ​​In order to simplify the change of the irradiation location, in the embodiment, a tool 200 for the lighting fixture 100 is disclosed as shown in FIG.

[0050] In the following, in order to facilitate understanding of this embodiment, the description may be made with reference to an X direction D41, a Y direction D42, and a Z direction D43 that are perpendicular to each other.

[0051] 7, the tool 200 includes a grip portion 6 and a plurality of protrusions 7. The tool 200 is made of a resin material. However, the tool 200 is not limited to this material, and may be made of metal or wood.

[0052] The grip portion 6 has lengths in each of the X direction D41, the Y direction D42, and the Z direction D43. That is, the grip portion 6 extends in the Z direction D43. The Z direction D43 is an example of a "predetermined direction" in the present invention. The grip portion 6 has a shape that is longer in the Z direction D43 than in the X direction D41 and the Y direction D42. The dimension of the grip portion 6 in the X direction D41 is longer than the dimension of the grip portion 6 in the Y direction D42. An example of this type of shape is a substantially rectangular parallelepiped shape.

[0053] The multiple protrusions 7 protrude radially from the grip portion 6 in the X direction D41 and the Y direction D42 intersecting the Z direction D43 from one end of the grip portion 6 in the Z direction D43. The multiple protrusions 7 are an example of the "multiple second protrusions" in the present invention. The X direction D41 and the Y direction D42 are an example of the "intersecting direction" in the present invention. The multiple protrusions 7 are engageable with the protrusion 513. Note that the surface of the multiple protrusions 7 opposite the grip portion 6 (i.e., the surface on one side in the Z direction D43) is a surface that is approximately parallel to the X direction D41 and the Y direction D42.

[0054] The worker rotates the lamp body U1 in the circumferential direction D31 (see FIG. 2) to tilt it with respect to the rotation mechanism U2. The worker pulls the reflecting member 55 out of the support 52 with his / her fingers to remove it from the mounting spring 525. As a result, as shown in FIG. 8, the reflecting member 55 is removed from the rotation mechanism U2. With the reflecting member 55 removed from the rotation mechanism U2, the worker holds the gripping portion 6 and inserts the multiple protrusions 7 into the inner circumferential surface 523 from the opening on the separation direction D22 side of the support 52 (see arrow A). Thereafter, the worker brings the multiple protrusions 7 into contact with the annular portion 511. The worker further rotates the tool 200 in the circumferential direction D51 (see arrow B) to engage one or two of the multiple protrusions 7 with the protrusions 513. In the engaged state, the worker further rotates the tool 200 in the circumferential direction D51. Accordingly, the support 51 rotates relative to the support 52. Therefore, the illumination location of the lighting fixture 100 can be easily changed.

[0055] The multiple protrusions 7 are preferably arranged at approximately equal angular intervals in the circumferential direction D51 of the axis Ax50. Therefore, any one of the multiple protrusions 7 can be easily engaged with the protrusion 513. The axis Ax50 passes through the center of the end face 61 located at the other end of the gripping part 6 in the Z direction D43, and is approximately parallel to the Z direction D43. In addition, one of two of the six protrusions 71 to 76 adjacent to each other in the circumferential direction D51 has a shape obtained by rotating the other one by 60° in the circumferential direction D51.

[0056] The outer diameter φ11 of the multiple protrusions 7 is preferably shorter than the inner diameter φ12 of the support 52. In detail, the outer diameter φ11 is the distance between the protruding ends of the two protrusions 7 that protrude in opposite directions. The inner diameter φ12 of the support 52 is the diameter of the inner circumferential surface 523 (see FIG. 5 ). This makes it easy to insert the multiple protrusions 7 into the inside of the inner circumferential surface 523 of the support 52.

[0057] Further, a through hole 62 is formed in the gripping portion 6. The through hole 62 improves the ease of use of the tool 200. In particular, the worker performs work at a relatively high place. If the tool 200 is dropped during work, the worker needs to go down to the floor and pick up the tool 200. The through hole 62 allows a strap to be attached to the tool 200 to prevent the tool 200 from dropping. Therefore, the ease of use of the tool 200 improves.

[0058] Moreover, the grip portion 6 has a shape that is long in the X direction D41 in a plan view in the Z direction D43. Therefore, it is easy for an operator to rotate the tool 200 while gripping the grip portion 6.

[0059] [Modifications of tool 200] As shown in FIG. 9, the tool 200 preferably further includes a plurality of protrusions 8. The plurality of protrusions 8 are an example of the "plurality of third protrusions" in the present invention. The plurality of protrusions 8 protrude from each of the plurality of protrusions 7 in one direction in the Z direction D43. In the embodiment, the plurality of protrusions 8 are six protrusions 81 to 86. The protrusions 81 to 86 are provided on the protrusions 71 to 76, respectively. The protrusions 81 to 86 are located closer to the axis Ax50 than the protruding ends of the protrusions 71 to 76. The outer diameter φ21 of the plurality of protrusions 8 is the same as the inner diameter φ22 (see FIG. 5) of the inner peripheral surface of the annular portion 511 (i.e., the support 51). Here, the term "same" means that the outer diameter φ21 and the inner diameter φ22 are the same as each other and that the outer diameter φ21 is slightly smaller than the inner diameter φ22. In detail, the outer diameter φ21 is the distance between the outermost portions of the two protrusions 8 protruding from the two protrusions 7 protruding in opposite directions. This allows the multiple protrusions 8 to fit inside the annular portion 511, making it easier to position the tool 200 relative to the support 51.

[0060] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various aspects without departing from the gist of the present invention.
