  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, in the figures, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

  First, with reference to FIG. 1, the structure of the lighting fixture 1 which concerns on this embodiment is demonstrated. FIG. 1 is a partial cross-sectional view showing a lighting fixture 1. The lighting fixture 1 is used by being attached to a ceiling. In the following description, “upper” and “lower” correspond to “upper” and “lower” when the lighting fixture 1 is attached to the ceiling.

  As shown in FIG. 1, the luminaire 1 includes a lamp body 2. The lighting fixture 1 according to the present embodiment is configured such that the lamp body 2 can be completely pulled out from the ceiling. FIG. 1 shows a state in which the lamp body 2 is arranged at the upper limit position (an example of the first position). In other words, FIG. 1 shows a state in which the lamp body 2 is not pulled out.

  The lamp body 2 includes a light emitting element array 21 (an example of a light source), a lens 22, and a heat sink 23. The light emitting element array 21 and the lens 22 are provided in the lower part of the lamp body 2, and the heat sink 23 is formed in the upper part of the lamp body 2.

  The light emitting element array 21 includes a plurality of light emitting elements. In the present embodiment, the light emitting element array 21 is an LED (Light Emitting Diode) array. In other words, the light emitting element array 21 includes a plurality of LEDs. The light emitting element array 21 may be, for example, a COB (Chip on Board) formed by sealing a plurality of LEDs with a phosphor. Alternatively, the light emitting element array 21 may be an SMD (Surface Mount Device) in which a plurality of LED chips are mounted on the mounting surface of the substrate and electrically connected to the conductive pattern of the substrate. Each LED chip is formed by integrating the LED and the phosphor into one unit.

  The lens 22 is disposed so as to cover the light emitting surface of the light emitting element array 21. The light emitted from the light emitting element array 21 passes through the lens 22 and is irradiated toward the outside of the lamp body 2. The lens 22 is not essential, and a cover member may be provided instead of the lens 22.

  The heat sink 23 has a plurality of heat radiation fins 24. The heat sink 23 is provided above the light emitting element array 21 and dissipates mainly heat generated from the light emitting element array 21 by a plurality of heat radiation fins 24. Thereby, the temperature rise of the light emitting element array 21 can be suppressed.

  In addition to the lamp body 2, the lighting fixture 1 includes a frame 3, a support portion 4, two sliders 5 (an example of a moving member), a pair of guide posts 6 (an example of a guide portion), and a plurality of And an attachment spring 7 (an example of an attachment member).

  The support part 4 supports the lamp body 2. Specifically, the support unit 4 includes a pair of support arms 41 (an example of an arm member), a connection arm 42 (an example of a connection member), and a top plate 43.

  The pair of support arms 41 face each other across the lamp body 2 and support the lamp body 2 so as to be tiltable. In the present embodiment, the distal end portion of each support arm 41 is connected to the lamp body 2 by a first screw 44. As a result, the lamp body 2 can be tilted about the first axis A1 that is the axis of the first screw 44.

  Specifically, the support arm 41 is fastened to the lamp body 2 by the first screw 44, and between the lamp body 2 and the support arm 41 and between the support arm 41 and the flange of the first screw 44. Due to the friction, the posture (angle) of the lamp body 2 is maintained. In addition, the lamp body 2 is moved only when a force greater than the frictional force generated between the lamp body 2 and the support arm 41 and between the support arm 41 and the flange of the first screw 44 is applied to the lamp body 2. Tilt is possible.

  The connecting arm 42 connects the pair of support arms 41. In the present embodiment, the base ends of the pair of support arms 41 are integrally connected via the connection arm 42. The top plate 43 is disposed above the connecting arm 42 and suspends and supports the connecting arm 42 so as to be able to turn. Specifically, the connecting arm 42 is supported so as to be pivotable about the second axis A2. As a result, the lamp body 2 can be turned around the second axis A2. The second axis A2 is parallel to the axis of light emitted from the lamp body 2 when the light emitting surface of the light emitting element array 21 is in a vertically downward posture.

  Each slider 5 is connected to the support portion 4. Specifically, each slider 5 is connected to the edge of the top plate 43. Each slider 5 may be integrally formed with the top plate 43 or may be fixed to the top plate 43.

  The pair of guide columns 6 support the sliders 5 so as to be tiltable and movable in the vertical direction (an example of a predetermined direction). In other words, the pair of guide columns 6 guide each slider 5 in the vertical direction. As the pair of guide columns 6 guide the sliders 5, the lamp body 2 and the support portion 4 are guided in the vertical direction. Specifically, each guide column 6 includes a pair of wall portions 61 and 62 extending in the vertical direction. The pair of wall portions 61 and 62 are opposed to each other, and each slider 5 moves in the vertical direction between the corresponding pair of wall portions 61 and 62. In FIG. 1, one wall portion 61 of the pair of wall portions 61 and 62 is shown on the front side in the drawing of FIG. 1. Further, the other wall portion 62 is shown on the back side in FIG.

  Each guide column 6 is supported by the frame body 3 and rises upward from the frame body 3. In the present embodiment, the lower end portion of each guide column 6 is fixed to the frame portion 31 of the frame body 3 by the second screw 63.

  An elongated hole 64 is formed in each guide column 6. Each long hole 64 has a long axis extending in the vertical direction. The shaft of the third screw 65 is inserted into each elongated hole 64 from the outside of the corresponding guide column 6. The shaft of the third screw 65 is fixed to the slider 5 positioned inside the corresponding guide column 6. Thus, the guide column 6 is sandwiched between the flange of the third screw 65 and the slider 5, and the slider 5 is supported by the guide column 6. Further, only when the slider 5 has a force greater than the frictional force generated between the flange of the third screw 65 and the guide column 6 and between the slider 5 and the guide column 6, The tightening force by the third screw 65 is adjusted so that the movement (up and down) and the tilt (swing) can be performed in the vertical direction. That is, each slider 5 has the third screw 65 so that the lamp body 2 and the support part 4 do not fall under its own weight regardless of the position where the lamp body 2 and the support part 4 are located within the movable range in the vertical direction. Is held by the corresponding guide column 6. Further, even if each slider 5 is tilted, each slider 5 is attached to the corresponding guide column 6 by the third screw 65 so that the posture (angle) of each slider 5 does not change due to the weight of the lamp body 2 and the support portion 4. Is retained.

  In this embodiment, each slider 5 is provided with a spring 65a. By providing the spring 65a, it is possible to adjust the force with which the third screw 65 tightens the slider 5 and the guide column 6 with higher accuracy. The spring 65a may be omitted.

  Each attachment spring 7 is fixed to the frame 3. In the present embodiment, the base end portion of each attachment spring 7 is fixed to the frame portion 31 of the frame body 3 by the fourth screw 71. In the present embodiment, two attachment springs 7 are used. The two mounting springs 7 are preferably arranged at equal intervals. Thereby, the frame 3 can be attached to a ceiling with the stable attitude | position.

  Then, with reference to FIG.2 and FIG.3, the structure of the lighting fixture 1 is demonstrated. FIG. 2 is a perspective view showing the lighting fixture 1, and FIG. 3 is another perspective view showing the lighting fixture 1. Specifically, FIG. 3 shows the luminaire 1 viewed from a direction different from that in FIG. 2 and 3 show a state in which the lamp body 2 is arranged at the upper limit position. 2 and 3, the attachment spring 7 is omitted.

  As shown in FIGS. 2 and 3, the frame 3 has an annular or substantially annular frame portion 31. Note that “substantially annular” indicates that the frame portion 31 is partially broken in the circumferential direction. The frame 3 further has a flange 32. The collar portion 32 is formed at the lower edge portion of the frame portion 31 so as to protrude outward. The frame 3 has an opening 33 through which the lamp body 2 can pass inside the frame portion 31 and the collar portion 32. The pair of guide columns 6 can guide each slider 5 so that the lamp body 2 passes through the opening 33 of the frame 3.

  As shown in FIG. 2, the wall portion 61 has a notch portion 66. Although not shown, the wall portion 62 also has a notch 66 similarly to the wall portion 61. The notch portion 66 is provided corresponding to a position where the slider 5 is located when the lamp body 2 is disposed at the upper limit position. In the present embodiment, the notch 66 is formed at the upper end of each wall 61, 62.

  Next, the slider 5 will be described with reference to FIGS. 4 and 5. FIG. 4 is an enlarged view of a part of the luminaire 1, and the slider 5 is viewed from the front. FIG. 5 is an enlarged view showing another part of the lighting fixture 1. Specifically, FIG. 5 shows an enlarged portion surrounded by a broken line in FIG. 4 and 5 show a state in which the lamp body 2 is disposed at the upper limit position. In FIG. 4, the third screw 65 is omitted.

  As shown in FIG. 4, in this embodiment, the slider 5 includes a wide portion 51 (an example of a first portion) having a width W <b> 1 narrower than a width W <b> 3 (interval) between the pair of wall portions 61 and 62. The wide portion 51 is disposed between the pair of wall portions 61 and 62 and moves in the vertical direction between the pair of wall portions 61 and 62. Note that as the width W1 of the wide portion 51 is closer to the width W3 between the pair of wall portions 61 and 62, the backlash of the slider 5 that may occur when the slider 5 (lamp body 2) is moved in the vertical direction. In other words, it is possible to suppress rattling of the lamp body 2. Therefore, the raising / lowering operation of the lamp body 2 can be smoothed. For this reason, in this embodiment, the width W1 of the wide portion 51 and the width W3 between the pair of wall portions 61 and 62 are substantially the same.

  The slider 5 further includes a narrow portion 52 (an example of a second portion) having a width W2 that is narrower than the width W1 of the wide portion 51. The narrow portion 52 is connected to the lower end of the wide portion 51 and is connected to the top plate 43.

  As shown in FIG. 5, the thickness T <b> 1 of the wide portion 51 is thicker than the thickness T <b> 2 of the narrow portion 52. That is, the narrow part 52 is thinner than the wide part 51. Further, the thickness T1 of the wide portion 51 is larger than the width W4 (height) of each of the wall portions 61 and 62, and the narrow portion 52 is located outside the pair of wall portions 61 and 62. Specifically, the narrow portion 52 is located closer to the center of the lamp body 2 (top plate 43) than the pair of wall portions 61 and 62. Therefore, the narrow portion 52 is separated from the pair of wall portions 61 and 62 and does not pass between the pair of wall portions 61 and 62.

  Furthermore, as shown in FIGS. 4 and 5, the wide portion 51 has a pair of inclined surfaces 53. The pair of inclined surfaces 53 are surfaces connected to the respective side surfaces of the narrow portion 52, and are positioned near the upper ends of the pair of wall portions 61 and 62 when the lamp body 2 is disposed at the upper limit position. In the present embodiment, the inclined surface 53 is a flat surface, but the inclined surface 53 may be a curved surface.

  Next, with reference to FIG. 6, the movement of each slider 5 and the tilting of the lamp body 2 arranged at the upper limit position will be described. FIG. 6 is a perspective view showing the lighting fixture 1 in a state where the sliders 5 and the lamp body 2 are tilted. FIG. 6 shows a state in which the lamp body 2 is disposed at the upper limit position. Further, in FIG. 6, the attachment spring 7 is omitted.

  As shown in FIG. 6, when the lamp body 2 is disposed at the upper limit position, the slider 5 can be tilted about the axis of the third screw 65. That is, when the pair of wall portions 61 and 62 extend to the upper end of the guide column 6, the tilt of the slider 5 is prevented by the pair of wall portions 61 and 62. On the other hand, in this embodiment, since the notch part 66 is provided in the upper end part of a pair of wall part 61,62, even if the slider 5 is tilted, the slider 5 and a pair of wall part 61,62 and Interference (contact) is unlikely to occur. Therefore, the slider 5 can be tilted.

  Therefore, according to the present embodiment, when the lamp body 2 is disposed at the upper limit position, the lamp body 2 is centered on the first screw 44 while tilting the support arm 41 about the third screw 65. Can be tilted. As a result, the tilting range of the lamp body 2 disposed at the upper limit position can be expanded.

  That is, when the slider 5 cannot tilt, the range until the lamp body 2 comes into contact with the inner peripheral surface of the frame portion 31 of the frame 3 is the tilt range of the lamp body 2 arranged at the upper limit position. On the other hand, according to this embodiment, it is possible to avoid interference (contact) between the lamp body 2 and the inner peripheral surface of the frame portion 31 by tilting the slider 5 and tilting the pair of support arms 41. It becomes possible. Therefore, the tilting range of the lamp body 2 arranged at the upper limit position can be expanded.

  Further, if the diameter of the inner peripheral surface of the frame portion 31 of the frame body 3 is made sufficiently larger than the diameter of the lamp body 2, the inner peripheral surfaces of the lamp body 2 and the frame portion 31 even when the slider 5 cannot tilt. It is possible to avoid interference (contact) with. However, in this case, it is necessary to enlarge the opening provided in the ceiling. On the other hand, according to this embodiment, the tilting range of the lamp body 2 can be expanded without increasing the diameter of the inner peripheral surface of the frame portion 31. In other words, the tilting range of the lamp body 2 can be expanded without expanding the opening provided in the ceiling.

  Further, if the width W1 of the slider 5 is made sufficiently smaller than the width W3 between the pair of wall portions 61 and 62, the slider 5 can be tilted without providing the notch portion 66. However, in this case, when the slider 5 is moved in the up and down direction, rattling of the slider 5 occurs, so that the lamp body 2 cannot be raised and lowered smoothly. On the other hand, according to this embodiment, the width W1 of the wide portion 51 is brought close to the width W3 between the pair of wall portions 61 and 62, and the tilting of the slider 5 is performed while smoothing the lifting and lowering operation of the lamp body 2. Can be made possible.

  In the present embodiment, the width W1 of the wide portion 51 and the width W3 between the pair of wall portions 61 and 62 are substantially the same so that the occurrence of rattling of the slider 5 can be suppressed. As a result, when the slider 5 tilts, the slider 5 partially protrudes through the notch portion 66 outside at least one of the pair of wall portions 61 and 62.

  Further, in the present embodiment, the notch portion 66 has the wide portion 51 partially formed on the outside of at least one of the pair of wall portions 61 and 62 via the notch portion 66 when the slider 5 tilts. It is provided so that it can protrude. In other words, the notch portion 66 is provided so that the upper ends of the pair of wall portions 61 and 62 are located near the lower end of the wide portion 51 when the lamp body 2 is disposed at the upper limit position. Therefore, for example, compared to the case where the shape of the slider 5 is a rectangular parallelepiped shape, the distance that the slider 5 is guided by the pair of wall portions 61 and 62 can be increased. Therefore, the stability of the raising / lowering operation of the slider 5 (lamp body 2) is improved.

  In the present embodiment, the narrow portion 52 is thinner than the wide portion 51 and is located outside the pair of wall portions 61 and 62. Accordingly, the narrow portion 52 does not interfere with the pair of wall portions 61 and 62 when the slider 5 is tilted. Therefore, the tilting range of the slider 5 can be expanded.

  In the present embodiment, the wide portion 51 has a pair of inclined surfaces 53. Thereby, the inclination angle of the slider 5 can be expanded in two directions. Furthermore, since the wide part 51 has a pair of inclined surfaces 53, the upper ends of the pair of wall parts 61 and 62 can be positioned further upward. In other words, the vertical length of the notch 66 can be further shortened. Therefore, the distance at which the slider 5 is guided by the pair of wall portions 61 and 62 can be increased. Furthermore, since the wide portion 51 has the pair of inclined surfaces 53, the posture (inclination) of the slider 5 can be corrected by the pair of wall portions 61 and 62 when the slider 5 is lowered. That is, when the slider 5 is lowered in the inclined posture, the one inclined surface 53 comes into contact with at least one upper end of the pair of wall portions 61 and 62. Then, one inclined surface 53 slides on the upper end of at least one of the pair of wall portions 61 and 62. As a result, the posture of the slider 5 is corrected to a state where the slider 5 is not tilted or is not substantially tilted.

  Then, with reference to FIG. 7, the method to attach the lighting fixture 1 to the ceiling 100 is demonstrated. FIG. 7 is a diagram illustrating a state in which the lighting fixture 1 is attached to the ceiling 100. FIG. 7 shows a state in which the lamp body 2 is disposed at the upper limit position.

  In the ceiling 100, for example, a circular opening 101 for attaching the lighting fixture 1 is formed. The diameter of the opening 101 is larger than the diameter of the frame portion 31 and smaller than the diameter of the flange portion 32. The operator keeps the opening 101 of the ceiling 100 until the flange 32 of the frame 3 abuts against the ceiling 100 in a state in which the mounting spring 7 is elastically deformed so that the distal end side of the mounting spring 7 approaches the side surface of the lamp body 2. The lighting fixture 1 is inserted into. Thereby, the attachment spring 7 is expanded by the elastic force, the ceiling 100 is sandwiched between the flange portion 32 of the frame body 3 and the attachment spring 7, and the frame body 3 (lighting fixture 1) is fixed to the ceiling 100. . Thus, the lighting fixture 1 is attached (locked) to the ceiling 100 by the elastic force of the attachment spring 7.

  Next, the position where the attachment spring 7 is fixed to the frame 3 will be described with reference to FIGS. 1 and 8. FIG. 8 is a top view showing the lighting apparatus 1. As shown in FIGS. 1 and 8, in the present embodiment, the two attachment springs 7 are adjacent to the portion where the pair of guide columns 6 are fixed to the frame 3 (frame 31). Fixed to. As described with reference to FIG. 7, in the state where the lighting fixture 1 is attached to the ceiling 100, the attachment spring 7 rises upward. For this reason, when the lamp body 2 arranged at the upper limit position is tilted, the lamp body 2 may come into contact (interference) with the mounting spring 7 and the lamp body 2 cannot be tilted at a desired angle. There is. On the other hand, by fixing each attachment spring 7 adjacent to the place where the pair of guide columns 6 is fixed to the frame body 3, the lamp body 2 and the attachment spring 7 are tilted when the lamp body 2 is tilted. Interference can be suppressed.

  FIG. 9 is a view showing the lighting fixture 1 in a state in which the lamp body 2 is pulled out. Specifically, FIG. 9 shows a state in which the lamp body 2 is lowered to the lower limit position (an example of the second position). 9 shows the lamp body 2 tilted by 90 degrees about the first axis A1 (the axis of the first screw 44) described with reference to FIG. 1 by a two-dot chain line.

  As shown in FIG. 9, the lighting fixture 1 which concerns on this embodiment can pull out the lamp main body 2 completely. When the lamp body 2 is completely pulled out from the ceiling, the lamp body 2 is located at the lower limit position. In other words, the lamp body 2 is guided from the upper limit position to the lower limit position by the pair of guide posts 6, thereby passing through the opening 33 (see FIGS. 2 and 3) of the frame 3 and completely from the ceiling. Pulled out.

  According to the present embodiment described above, the tilt angle of the lamp body 2 in the state of being housed in the back of the ceiling can be expanded without enlarging the opening 101 provided in the ceiling 100.

  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-described embodiment, and can be implemented in various modes without departing from the gist thereof.
