[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.
[0017] A lighting fixture 200 according to this embodiment will be described with reference to Figures 1 to 3. Figure 1 is a perspective view showing the lighting fixture 200 according to this embodiment. Figure 2 is a side view showing the lighting fixture 200 according to this embodiment. Figure 3 is a cross-sectional view of the lighting fixture 200 according to this embodiment. Figure 3 shows a cross-section along a vertical direction Z passing through a central axis A11 of a lighting fixture body 80 and a central axis A12 of a frame body 103, which will be described later. Hereinafter, the vertical direction Z will also be referred to as vertically downward or downward. The direction opposite to the vertical direction Z will also be referred to as upward.
[0018] Lighting fixture 200 is attached to a mounting target such as a building. Typically, the mounting target is a ceiling (not shown) inside a room. However, the mounting target may also be a side wall inside a room. Lighting fixture 200 may also be attached to a mounting target outside a room. Below, a representative example of lighting fixture 200 attached to a ceiling will be described.
[0019] As shown in FIGS. 1 to 3 , the lighting fixture 200 includes a lighting fixture main body 80, a frame body 103 to be attached to an attachment target, multiple mounting springs 105 that secure the frame body 103 to an attachment position on the attachment target, multiple fixing springs 120, a tilting mechanism 26, and an angle indicator 40. The lighting fixture main body 80 includes a light source unit 111, a housing 125, and a heat sink 70. As an example, the lighting fixture main body 80 has a substantially cylindrical shape. The frame body 103 has an annular shape. The frame body 103 is fixed to the ceiling by the mounting springs 105. The lighting fixture main body 80 is located inside the frame body 103. When the lighting fixture 200 is attached to a ceiling in a room, a central axis A12 of the frame body 103 extends along the vertical direction Z. A central axis A11 of the lighting fixture main body 80 extends along the vertical direction Z, for example. In this embodiment, the central axis A11 is positioned offset from the central axis A12 of the frame body 103 in the radial direction R of the frame body 103. The radial direction R is perpendicular to the vertical direction Z.
[0020] As shown in FIGS. 2 and 3, the light source unit 111 emits light in a predetermined direction D1. The predetermined direction D1 is, for example, the lower side of the light source unit 111. Specifically, the light source unit 111 includes a light source module 111A formed by a substrate (not shown) and a plurality of light-emitting elements arranged on the substrate, and a substantially cylindrical housing 125 that accommodates the light source module 111A. Typically, the light-emitting elements are LEDs (Light Emitting Diodes). The light-emitting elements are placed on a mounting surface of the substrate and emit light toward the opposite side to the mounting surface. The light emitted from the light-emitting elements is diffused by a diffusing member (not shown) and is emitted from the lower side of the light source unit 111. The light source unit 111 is an example of a light source unit.
[0021] The housing 125 has a substantially cylindrical shape and houses the light source unit 111. The heat sink 70 is provided above the housing 125. For example, the heat sink 70 is fixed to the top of the light source unit 111 via a heat dissipation sheet (not shown). The heat sink 70 dissipates heat using a plurality of fins, suppressing a rise in temperature of the light source unit 111. The heat sink 70 is formed from a material with high thermal conductivity, and is preferably formed from, for example, a metal. Among metals, it is preferably formed from, for example, aluminum or an aluminum alloy, in consideration of ease of molding and the weight reduction of the lighting fixture 200.
[0022] In this embodiment, the frame 103 includes a truncated cone 107 and an outer frame 103A that surrounds the outer periphery of the cone 107. Typically, the cone 107 is provided on the lower side of the housing 125. Therefore, light emitted from the light source unit 111 of the lamp body 80 passes through the inside of the cone 107 of the frame 103. In other words, the lamp body 80 emits light through the inside of the frame 103.
[0023] For example, the cone 107 includes a reflecting mirror (not shown). The reflecting mirror reflects the light emitted from the light source unit 111. For example, the reflecting mirror is a reflecting mirror having a truncated cone shape. The reflecting mirror is disposed on the inner peripheral surface of the cone 107. The reflecting mirror reflects a portion of the light emitted from the light source unit 111. The light emitted from the light source unit 111 is further diffused by reflection from the reflecting mirror. Note that the inner peripheral surface of the cone 107 may not have a reflecting mirror and may be painted white or black.
[0024] The lighting fixture body 80 is supported by the frame body 103 via a plurality of fixing springs 120 (FIGS. 1 and 2). In this embodiment, the plurality of fixing springs 120 are disposed between the lighting fixture body 80 and the frame body 103. Each of the plurality of fixing springs 120 biases the lighting fixture body 80 upward relative to the frame body 103, which is the opposite side to the light emission direction.
[0025] The lamp body 80 and the frame body 103 are connected to each other via a tilting mechanism 26. In this embodiment, the tilting mechanism 26 connects the housing 125 and the cone 107. The tilting mechanism 26 tilts the lamp body 80 with respect to the frame body 103. In other words, the tilting mechanism 26 adjusts the tilt angle of the lamp body 80 with respect to the frame body 103. More specifically, the tilting mechanism 26 switches between a state in which the lamp body 80 is not tilted with respect to the frame body 103 and a state in which the lamp body 80 is tilted with respect to the frame body 103. The configuration of the tilting mechanism 26 will be described later.
[0026] In the lighting fixture 200 shown in FIGS. 2 and 3, the central axis A11 of the lighting fixture body 80 and the central axis A12 of the frame body 103 are parallel to each other. In other words, the tilt angle of the central axis A12 of the frame body 103 relative to the central axis A11 of the lighting fixture body 80 is 0°. The tilt angle of the central axis A12 of the frame body 103 relative to the central axis A11 of the lighting fixture body 80 is also the tilt angle of the lighting fixture body 80 relative to the frame body 103. Hereinafter, the state in which the central axes A11 and A12 are parallel to each other will be referred to as the "first state." In the first state, the tilt angle of the lighting fixture body 80 relative to the frame body 103 is 0°, and the lighting fixture body 80 is not tilted relative to the frame body 103.
[0027] Next, angle indicator 40 provided on lighting device 200 according to this embodiment will be described with reference to Fig. 4. Fig. 4 is a perspective view of lighting device 200 on the side on which angle indicator 40 is provided.
[0028] The angle indicator 40 indicates the tilt angle of the lamp body 80 relative to the frame 103. Specifically, the angle indicator 40 indicates the tilt angle θ1 ( FIG. 6 ) of the central axis A12 of the frame 103 relative to the central axis A11 of the lamp body 80. When the optical axis of the light source module 111A coincides with the central axis A11, the angle indicator 40 indicates the angle of the optical axis. Typically, the angle indicator 40 is a sheet-like member on which scales 41A, 41B ( FIGS. 5 and 7 ), and 41C ( FIGS. 8 to 11 ) indicating angles are provided. The angle indicator 40 is a sheet-like member having scales 41A, 41B, and 41C provided on one side thereof and an adhesive applied to the other side thereof. Note that the angle indicator 40 is not limited to a sticker, and may be a printed or engraved mark indicating the angle provided on the outer peripheral surface 125A of the housing 125. The scales 41A, 41B, and 41C are arranged side by side along the direction in which the central axis A11 of the lamp body 80 extends, which is the light emission direction. The scales 41A, 41B, and 41C are arranged in this order in the light emission direction. In other words, the scale 41A is arranged above the scales 41B and 41C, and the scale 41B is arranged above the scale 41C.
[0029] By providing angle indicator 40 to lighting fixture 200 in which lighting fixture body 80 is tiltable relative to frame body 103, it becomes easier to grasp the emission direction of light emitted through frame body 103 relative to frame body 103, for example, when setting the tilt angle of lighting fixture body 80. As a result, when frame body 103 is attached to an attachment object, it becomes easy to grasp the emission direction of light passing through the attachment object.
[0030] The tilt mechanism 26 has a first rotation mechanism 261. The first rotation mechanism 261 rotates the lamp body 80 relative to the frame 103 in a circumferential direction C1 of a rotation axis A21 that intersects with the light emission direction.
[0031] The first rotation mechanism 261 makes it possible to easily tilt the direction of light emitted from the lamp body 80 relative to the frame body 103 simply by rotating the lamp body 80 in the circumferential direction C1.
[0032] Specifically, the first rotation mechanism 261 includes a pair of through holes (not shown) provided in the housing 125, a pair of protrusions (not shown) provided in the frame 103, and a rotation axis A21. Each of the pair of through holes penetrates the housing 125 in the radial direction R. The pair of through holes are arranged opposite each other in the radial direction R across the central axis A11 that is the central axis of the housing 125. Each of the pair of protrusion members protrudes upward from the frame 103 and has, for example, a screw hole that penetrates in the radial direction R.
[0033] When the housing 125 is fastened with screws through a pair of through-holes into the screw holes of the pair of protruding members, a rotation axis A21 is formed between the pair of protruding members. This allows the lamp body 80 and the frame body 103 to rotate relative to each other in a circumferential direction C1 around the rotation axis A21. The circumferential direction C1 is an example of a first circumferential direction.
[0034] The tilt mechanism 26 also has a second rotation mechanism 262. Specifically, the lamp body 80 is supported by a plurality of fixing springs 120 on the outer frame 103A of the frame body 103, and thus the lamp body 80 is movable together with the cone 107 in the circumferential direction C2 of the outer frame 103A relative to the outer frame 103A. Typically, three fixing springs 120 are fixed to the outer frame 103A (FIGS. 1 and 2), but the number of fixing springs 120 may be two or more. The plurality of fixing springs 120 are arranged at approximately equal intervals in the circumferential direction C2 of the outer frame 103A. The lamp body 80 is placed on the plurality of fixing springs 120. The plurality of fixing springs 120 are an example of a second rotation mechanism 262 that rotates the lamp body 80 in the circumferential direction C2 relative to the frame body 103. The circumferential direction C2 is an example of a second circumferential direction.
[0035] The second rotation mechanism 262 can further change the light emission direction from the lighting fixture body 80 to the circumferential direction C2 while the light emission direction from the first rotation mechanism 261 remains tilted relative to the frame body 103, thereby widening the setting range of the light emission direction. In this case, if the lighting fixture 200 is provided with the angle display 40, it is easy to grasp the tilt angle of the lighting fixture body 80 relative to the frame body 103 regardless of which direction the light emission direction is facing in the circumferential direction C2.
[0036] 4, the angle indicator 40 is provided on the housing 125. Specifically, the angle indicator 40 is provided on the housing 125 at a position away from the rotation axis A21 in a direction intersecting the rotation axis A21.
[0037] By providing the angle indicator 40 at a position away from the rotation axis A21, the intervals between the multiple scales on the angle indicator 40 can be made wider than when, for example, radial scales are provided on an extension of the rotation axis A21. This makes it easier to visually distinguish the scales that indicate the tilt angle of the lamp body 80, and makes it easier to adjust the tilt angle.
[0038] Typically, the housing 125 has an outer peripheral surface 125A that extends along the light emission direction. The angle indicators 40 are provided on the outer peripheral surface 125A of the housing 125. The frame 103 has a cover portion 27. The cover portion 27 covers at least a portion of the angle indicators 40. In this embodiment, the cover portion 27 is cylindrical, is attached above the cone 107, and covers the entire lower end side of the housing 125.
[0039] As shown in FIG. 4 , in lighting fixture 200 in the first state, cover portion 27 covers a portion of angle indicator 40 below scale 41A. When scale 41A is viewed from the position of upper end 271 of cover portion 27 in vertical direction Z, from the outside toward the inside in radial direction R, scale 41A and upper end 271 of cover portion 27 appear to overlap each other. Hereinafter, the state in which scale 41A and end 271 appear to overlap each other will also be referred to as scale 41A being in an "overlapping position" with upper end 271 of cover portion 27 in vertical direction Z. Therefore, scale 41A corresponds to an inclination angle of "0°." Furthermore, cover portion 27 is provided with indicator 272 indicating end 271. For example, indicator 272 is an arrow-shaped sticker, print, or engraving pointing to end 271. When the end 271 and the scale 41A are in an "overlapping position" in the vertical direction Z, the indicator 272 points to the scale 41A. Therefore, the tilt angle of the lamp body 80 with respect to the frame 103 can be easily grasped.
[0040] Next, with reference to FIGS. 5 to 7, the lighting fixture 200 will be described in a state in which the lighting fixture body 80 is tilted at an angle θ1 with respect to the frame body 103. In the lighting fixture 200, when the lighting fixture body 80 rotates from the first state in the circumferential direction C1 about the rotation axis A21 by an angle θ1, the lighting fixture body 80 enters a state in which it is tilted at an angle θ1 with respect to the frame body 103. In this state, the angle between the central axis A11 of the lighting fixture body 80 and the central axis A12 of the frame body 103 is angle θ1. The angle θ1 indicates the tilt angle of the central axis A12 of the frame body 103 with respect to the central axis A11 of the lighting fixture body 80. As an example, the tilt angle of the central axis A12 of the frame body 103 with respect to the central axis A11 of the lighting fixture body 80 is 15°. Hereinafter, the state in which the tilt angle of central axis A12 with respect to central axis A11 is 15° will be referred to as the "second state." Fig. 5 is a side view showing lighting fixture 200 in the second state. Fig. 6 is a cross-sectional view of lighting fixture 200 in the second state. Fig. 6 shows a cross-section along vertical direction Z passing through central axis A11 of lamp body 80 and central axis A12 of frame body 103. Fig. 7 is a perspective view of lighting fixture 200 in the second state, showing the side on which angle indicator 40 is provided.
[0041] 5 to 7, lighting device 200 in the second state emits light in a predetermined direction D2. Predetermined direction D2 is a direction inclined at an angle θ1 from below, and is the direction in which central axis A11 of lighting body 80 of lighting device 200 in the second state extends.
[0042] 7, in lighting device 200 in the second state, cover portion 27 covers the portion of angle indicator 40 below scale 41B. In other words, scale 41B is located at the same position in the vertical direction Z as upper end 271 of cover portion 27. Therefore, scale 41B corresponds to an inclination angle of 15°.
[0043] In this embodiment, since scale 41B is located below scale 41A, the area of the portion of angle display 40 that is covered by cover portion 27 in the second state is smaller than the area of the portion that is covered by cover portion 27 in the first state.
[0044] In this way, in lighting fixture 200, the amount of the portion of angle indicator 40 that is covered by cover portion 27 varies depending on the tilt angle. Therefore, an operator adjusting the tilt angle can easily recognize whether the tilt angle is increasing or decreasing based on an increase or decrease in the area of the portion of angle indicator 40 that is covered by cover portion 27.
[0045] 2 to 7, when the lighting fixture body 80 is tilted with respect to the frame body 103, the angle indicator 40 is provided at a position facing away from the side facing the frame body 103. Specifically, when the light emission direction faces the vertical direction Z with respect to the radial direction R, the angle indicator 40 is provided on the outer peripheral surface 125A of the housing 125 on the side opposite to the vertical direction Z.
[0046] This makes it easier to see the angle indicators 40 when the outer peripheral surface 125A is viewed from the outside in the radial direction R.
[0047] Next, a first example of the arrangement of the angle indicator 40 will be described with reference to Fig. 8. Fig. 8 is a diagram showing a first example of the angle indicator 40 arranged on the housing 125. Fig. 8 shows an example in which the angle indicator 40 is a rectangular sticker.
[0048] The angle indicator 40 is attached to the end (lower end) of the housing 125 on the light emission direction side. Specifically, the housing 125 further has an end face 125B that extends inward from the outer circumferential surface 125A in the radial direction R and faces the light emission direction side. In the light emission direction, the lower end 401 of the angle indicator 40 and the end face 125B are at the same position. The end face 125B is an example of a first surface.
[0049] By aligning the position of the lower end 401 of the angle display 40 with the position of the end face 125B, the angle display 40 can be more easily positioned in the specified position, improving the accuracy of the tilt angle indicated by the scale on the angle display 40.
[0050] Next, a second example of the arrangement of angle indicators 40 will be described with reference to Fig. 9. Fig. 9 is a diagram showing a second example of angle indicators 40 arranged on housing 125. Fig. 9 is the same as Fig. 8 except that the shape of the lower part of housing 125 is different.
[0051] The housing 125 shown in FIG. 9 has a recess 126 at its lower end, recessed inward in the radial direction R from the outer circumferential surface 125A. The outer circumferential surface 125A and the end surface 125B are connected to each other via the recess 126. The recess 126 is provided with an end surface 125C that extends inward in the radial direction R from at least the outer circumferential surface 125A and faces the light emission direction. In other words, the housing 125 further has an end surface 125C that extends inward in the radial direction R from the outer circumferential surface 125A and faces the light emission direction. The end surface 125C is an example of a first surface. The recess 126 may be provided at a position other than the lower end of the housing 125. For example, the recess 126 is a groove that is provided in the outer circumferential surface 125A of the housing 125 and extends in the circumferential direction C2.
[0052] Next, a third example of the arrangement of angle indicators 40 will be described with reference to Fig. 10. Fig. 10 is a diagram showing a third example of angle indicators 40 arranged on housing 125. Fig. 10 is the same as Fig. 8 or 9 except that the shape of the lower portion of housing 125 is different.
[0053] The housing 125 shown in FIG. 10 has a protrusion 127 at its lower end that protrudes outward in the radial direction R from the outer peripheral surface 125A. The outer peripheral surface 125A and the end surface 125B are connected to each other via the protrusion 127. The protrusion 127 is provided with an end surface 125D that extends outward in the radial direction R from at least the outer peripheral surface 125A and faces the light emission direction. In other words, the housing 125 further has an end surface 125D that extends inward in the radial direction R from the outer peripheral surface 125A and faces the light emission direction. The end surface 125D is an example of a second surface. The protrusion 127 may be provided at a position other than the lower end of the housing 125. For example, the protrusion 127 is a flange that is provided on the outer peripheral surface 125A of the housing 125 and extends in the circumferential direction C2.
[0054] By aligning the position of the lower end 401 of the angle indicator 40 with the position of the end face 125D, it becomes easier to place the angle indicator 40 in the specified position when assembling the lighting device 200, and the accuracy of the tilt angle indicated by the scale on the angle indicator 40 is improved.
[0055] Next, a fourth example of the arrangement of the angle indicator 40 will be described with reference to Fig. 11. Fig. 11 is a diagram showing a fourth example of the angle indicator 40 arranged on the housing 125.
[0056] In the fourth example, the angle indicator 40 is not covered by the cover portion 27. Specifically, the cover portion 27 has a cutout portion 273 that is cut out downward from the end portion 271. The angle indicator 40 is located in the cutout portion 273. For example, the cutout portion 273 has a shape that follows the outer shape of the angle indicator 40.
[0057] In place of the indicator 272, the cover part 27 provided with the cutout part 273 is provided with an indicator 274. The indicator 274 is an arrow-shaped sticker, printed lettering, engraved marking, or the like that points to the cutout part 273. For example, when the indicator 274 is positioned to point to the scale 41B of the angle indicator 40, the tilt angle of the lamp body 80 with respect to the frame 103 is "15°." In addition to the scales 41A, 41B, and 41C, the angle indicator 40 is provided with numerical indicators 42A, 42B, and 42C that indicate the angles corresponding to the scales 41A, 41B, and 41C, respectively. The numerical indicators 42A, 42B, and 42C are arranged in positions on the angle indicator 40 that correspond to the scales 41A, 41B, and 41C, respectively.
[0058] In the present embodiment, the cone 107 is provided on the frame 103, but this is not limiting and the cone 107 may be provided on the lamp body 80. When the cone 107 is provided on the lamp body 80, the first rotation mechanism 261 rotates the lamp body 80 together with the cone 107 relative to the outer frame 103A in the circumferential direction C1 of the rotation axis A21. In this case, the cover part 27 is attached above the outer frame 103A and covers at least a portion of the angle display 40.
[0059] In this embodiment, for example, the cone 107 provided on the frame body 103 may be located more inward in the radial direction R than the outer circumferential surface 125A of the housing 125 of the lamp body 80. In this case, the angle indicator 40 is disposed on the outer circumferential surface of the cone 107, for example, and the cover part 27 is provided on the lamp body 80 rather than on the frame body 103.
[0060] In addition, in this embodiment, the tilt angle of the lighting fixture body 80 relative to the frame body 103 is adjusted by the tilt mechanism 26 which combines the first rotation mechanism 261 and the second rotation mechanism 262, but the tilt mechanism 26 may also adjust the tilt angle of the lighting fixture body 80 relative to the frame body 103 by a structure other than the combination of the first rotation mechanism 261 and the second rotation mechanism 262.
