DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than these embodiments and modifications are possible according to the design, etc., as long as they do not deviate from the technical idea of ​​the present disclosure.

[0013] (Embodiment) Hereinafter, a lighting fixture 1, a light source device 3, and a lighting fixture body 2 according to this embodiment will be described with reference to FIGS. 1A to 8. FIG.

[0014] (1) Overview The lighting fixture 1 of the present embodiment is, for example, a lighting fixture used as a downlight. In the present embodiment, the lighting fixture 1 will be described as a downlight as an example. The lighting fixture 1 shown in Figs. 1A and 1B is attached to a mounting portion provided on a ceiling or the like.

[0015] As shown in Fig. 2, the lighting fixture 1 of this embodiment includes a lighting fixture body 2 and a light source device 3. In Fig. 1A, the lighting fixture body 2 and the light source device 3 are at the same height on the underside 101 of the lighting fixture 1. In contrast, in the lighting fixture 1 shown in Fig. 1B, the light source device 3 is located above the lighting fixture body 2. That is, in the lighting fixture 1 of this embodiment, the height of the light source device 3 with respect to the lighting fixture body 2 can be changed.

[0016] As shown in FIG. 5, the light source device 3 includes a light source 30, a panel 31 that transmits light from the light source 30, and a first attachment portion 33 that is detachably attached to the lighting fixture body 2 (see FIG. 2).

[0017] As shown in FIG. 2, the lighting fixture body 2 includes a frame 20 and a second attachment portion 21 to which the first attachment portion 33 of the light source device 3 is detachably attached.

[0018] At least one of the first attachment portion 33 and the second attachment portion 21 includes a movable mechanism 5 that allows the panel 31 to be changed to a plurality of heights with respect to the lower surface 101 of the lighting fixture body 2 when the light source device 3 is attached to the lighting fixture body 2. In this embodiment, the second attachment portion 21 includes the movable mechanism 5 as shown in FIG.

[0019] By providing the luminaire body 2 with the movable mechanism 5, it is possible to change the height of the light source device 3 relative to the luminaire body 2, i.e., the height of the panel 31 and the light source 30 (see FIG. 8) relative to the luminaire body 2. If the height of the panel 31 and the light source 30 can be changed, for example, glare can be reduced. The glare of the luminaire 1 is evaluated based on the angle between the panel 31 and the line of sight, with the angle when the panel 31 is viewed from directly below the luminaire 1 being 90 degrees. The flat position (see FIG. 1A) is when the bottom surface 101 of the luminaire 1 and the panel 31 are at the same height, and the height-changed position (see FIG. 1B) is when the panel 31 is higher than the bottom surface 101 of the luminaire 1. For example, when the angle between the panel 31 and the line of sight is 15 degrees, the geometric mean luminance (cd / m 2 ) can be reduced by about 50%. Also, by changing the height of the panel 31 and the light source 30, the area where glare occurs can be reduced by about 30%. In other words, by changing the height of the panel 31 and the light source 30, glare can be reduced. Here, the geometric mean luminance is a method of evaluating the average value of luminance within the visual field by the geometric mean. The sense of brightness is proportional to the logarithm of the luminance. When averaging the luminance within the visual field, a value that is more suited to human senses can be obtained by averaging the luminance within the visual field by the geometric mean rather than the arithmetic mean. Note that the luminance within the visual field may be averaged by the arithmetic mean.

[0020] As shown in FIG. 3, the movable mechanism 5 includes a holding groove 51 that slidably holds the protrusion 50 of the first mounting portion 33 in the second mounting portion 21. In the movable mechanism 5, the protrusion 50 and the fixing protrusion 52 of the holding groove 51 are fitted together, so that the light source device 3 can be attached to the lighting fixture main body 2. Since the holding groove 51 branches into at least two or more in the vertical direction (height direction of the lighting fixture), when the light source device 3 is attached to the lighting fixture main body 2, the panel 31 and the light source 30 (see FIG. 8) can be attached at least two or more different heights. In other words, the user can change the height at which the panel 31 and the light source 30 are installed depending on the number of branches of the holding groove 51. In this embodiment, the holding groove 51 has a first holding groove 51A and a second holding groove 51B as shown in FIG. 3. In addition, the holding groove 51 has a first fixing protrusion 52A and a second fixing protrusion 52B for fixing the protrusion 50. Specifically, the movable mechanism 5 has a first fixing protrusion 52A corresponding to the first holding groove 51A, and a second fixing protrusion 52B corresponding to the second holding groove 51B.

[0021] As shown in FIG. 4, the light source device 3 includes a grip portion 34 provided on an upper surface 102 of a base 37 of the light source device 3. The grip portion 34 has, for example, a cross shape. The light source device 3 has a drive portion 35 (see FIG. 5) that drives the light source 30 (see FIG. 5). The drive portion 35 is provided, for example, inside the grip portion 34. When the drive portion 35 is built into the upper surface 102 of the base 37 of the light source device 3, when the light source device 3 is viewed from the outside, it appears as a convex shape formed on the upper surface 102 of the base 37. By making this convex shape into the cross-shaped grip portion 34, it becomes easier for a user to hold the light source device 3. As shown in FIG. 4, the light source device 3 further includes a power input portion 40 that inputs power. When power is input from the power input portion 40, the light source device 3 drives the light source 30 by the drive portion 35, and light is emitted from the light source 30. The light emitted from the light source 30 is diffused by the panel 31.

[0022] The lighting fixture body 2 (see FIG. 2) further includes an outer flange 24 and an attachment spring 22. The outer flange 24 and the frame 20 are also called a flange 6, and the lighting fixture 1 is attached to a ceiling by sandwiching a ceiling board between the attachment spring 22 and the flange 6.

[0023] (2) Composition The configuration of a lighting fixture 1 of this embodiment will be described. As shown in Figures 1A and 1B, the lighting fixture 1 includes a lighting fixture main body 2 and a light source device 3. The lighting fixture main body 2 and the light source device 3 will each be described.

[0024] (2-1) Lighting fixture body As shown in FIG. 2, the lighting device main body 2 includes a frame body 20, a plurality of (two in this embodiment) second mounting portions 21 for removably mounting the first mounting portions 33 of the light source device 3, a plurality of (two in this embodiment) mounting springs 22, and a plurality of (two in this embodiment) insertion portions 23.

[0025] The frame body 20 has an opening 8, and as shown in FIG. 1A, the lower surface of the frame body 20 (the lower surface 101 of the lighting fixture 1) has an outer flange 24. The outer flange 24 protrudes from the lower end of the frame body 20 in a direction perpendicular to the frame body 20. The frame body 20 is made of, for example, polycarbonate. The frame body 20 and the outer flange 24 together are also called a flange 6 (see FIG. 2).

[0026] As shown in FIG. 2, a plurality of second attachment parts 21 (two in this embodiment) are provided on the upper surface of the frame body 20. In this embodiment, the second attachment part 21 includes an insertion part 23, a sliding part 25, and a movable mechanism 5. The movable mechanism 5 is a mechanism that changes the height of the panel 31 and the light source 30. Here, the height means the height based on the lower surface 101 of the lighting fixture 1. In other words, the movable mechanism 5 is a mechanism that can change the height of the panel 31 and the light source 30 from the lower surface 101 of the lighting fixture 1. The movable mechanism 5 has a plurality of holding grooves 51 (two in this embodiment) and a plurality of fixing protrusions 52 (two in this embodiment). In this embodiment, the holding groove 51 has a first holding groove 51A and a second holding groove 51B. The fixing protrusion 52 has a first fixing protrusion 52A and a second fixing protrusion 52B. That is, the second attachment portion 21 includes an insertion portion 23, a sliding portion 25, a first holding groove 51A, a second holding groove 51B, a first fixing protrusion 52A, and a second fixing protrusion 52B.

[0027] As shown in FIG. 3, the insertion portion 23 is an insertion opening into which the first mounting portion 33 (the protrusion 50) is inserted. The protrusion 50 is inserted into the second mounting portion 21 through the insertion portion 23. The insertion portion 23 is formed by a cut in the frame body 20. The sliding portion 25 is a cut along the circumferential direction of the second mounting portion 21. The holding groove 51 is formed by a cut perpendicular to the circumferential direction of the second mounting portion 21 and a plurality of (two in this embodiment) cuts along the circumferential direction of the second mounting portion 21 connected thereto. The user can selectively change the height of the panel 31 and the light source 30 by selecting one of the plurality of holding grooves 51. Each of the plurality of holding grooves 51 has a fixing protrusion 52. The fixing protrusion 52 fits into the protrusion 50 to fit the first mounting portion 33 and the second mounting portion 21.

[0028] 2 is a part for attaching the lighting fixture 1 to a ceiling. The mounting spring 22 and the flange 6 sandwich the ceiling board to fix the lighting fixture 1 to the ceiling.

[0029] (2-2) Light source device As shown in FIG. 5, the light source device 3 includes a base 37, a panel 31, an LED (Light Emitting Diode) module 38, a drive unit 35, a power input unit 40, a grip unit 34, and a first mounting unit 33 that is detachably attached to the lighting fixture body 2.

[0030] The base 37 and the gripping portion 34 are integrated together as shown in Figures 2 and 4. The base 37 has a cylindrical shape and incorporates an LED module 38 therein. The base 37 is made of, for example, polycarbonate.

[0031] The grip portion 34 is formed integrally with the base 37 of the light source device 3. The grip portion 34 has, for example, a cross shape, which makes the grip portion 34 easy to grasp. A drive unit 35 is built into the grip portion 34. The grip portion 34, like the base 37, is formed of polycarbonate.

[0032] The panel 31 transmits light from the light source 30. The panel 31 converts the light of an LED, which is a point light source propagating inside the panel 31, into light of a surface light source, and diffuses the converted light in all directions. The panel 31 is fitted into a base 37 of the light source device 3. The panel 31 is formed of, for example, polycarbonate.

[0033] The LED module 38 is a module using one or more (15 in this embodiment, see FIG. 8) LED elements as the light source 30. The LED elements as the light source 30 are white LED elements. The white LED elements used in this embodiment emit white light by combining, for example, a blue LED element with red and green phosphors. The blue LED elements use, for example, aluminum indium gallium nitride (AlInGaN) or indium gallium nitride (InGaN) as a light-emitting layer. As shown in FIG. 7, the LED module 38 is housed in the base 37 of the integrated base 37 and gripping portion 34. As shown in FIG. 8, when the panel 31 fitted to the light source device 3 is removed, the circular LED module 38 appears. Fifteen LED elements as the light source 30 are arranged so as to be distributed throughout the LED module 38. The LED module 38 is attached to the base 37 by three heat staking 41 (see FIG. 8).

[0034] As shown in Fig. 5, the driving unit 35 receives power from the power input unit 40 and converts it into a voltage for driving the LED module 38. The driving unit 35 is built into the gripping unit 34 of the unit in which the base body 37 and the gripping unit 34 are integrated, so that the board of the driving unit 35 is parallel to the vertical direction of the lighting fixture 1 (see Fig. 7).

[0035] The power input unit 40 is a lead wire that supplies power to the drive unit 35. The power input unit 40 is connected to a commercial power source from the upper surface 102 of the light source device 3 via an attic or the like. The lead wire that is the power input unit 40 is formed of, for example, a copper wire.

[0036] 6A to 6C show a top view, a side view, and a cross-sectional view, respectively, of the first mounting portion 33. As shown in Fig. 6A and Fig. 6B, the protrusion 50 serving as the first mounting portion 33 protrudes from the side surface 103 of the base body 37 in this embodiment.

[0037] The first mounting portion 33 can be detachably attached to the lighting fixture body 2. In this embodiment, as shown in FIG. 4, the first mounting portion 33 has a plurality of (two in this embodiment) protrusions 50. As shown in FIG. 6C, the cross section of the first mounting portion 33, i.e., the protrusions 50, has an H-shape. The cross-sectional shape of the protrusions 50 fits into the fixing protrusions 52 of the holding grooves 51 of the first mounting portion 33 described above, thereby preventing the first mounting portion 33 and the second mounting portion 21 from coming off. The protrusions 50, which are the first mounting portion 33, are formed of, for example, polycarbonate, similar to the base 37 and the grip portion 34.

[0038] (3) Installation, removal, and height adjustment The installation and replacement of the lighting fixture 1 will be described. As shown in Fig. 2, the lighting fixture 1 of this embodiment can be separated into a lighting fixture main body 2 and a light source device 3. Therefore, even if the lighting fixture main body 2 or the light source device 3 is damaged, the lighting fixture 1 can be repaired and continued to be used by replacing the damaged portion.

[0039] The user integrates the lighting fixture body 2 and the light source device 3. In this case, the user grasps the cross-shaped gripping portion 34, inserts the light source device 3 from the opening 8 of the lighting fixture body 2, and pulls it up. Here, the user rotates the light source device 3 or the lighting fixture body 2 to align the protrusion 50 of the light source device 3 with the insertion portion 23 of the second attachment portion 21 of the lighting fixture body 2. When the protrusion 50 is inserted into the insertion portion 23, the user rotates the protrusion 50 along the sliding portion 25 so that the light source device 3 rotates relative to the lighting fixture body 2. By rotating, the protrusion 50 slides on the sliding portion 25 and reaches the movable mechanism 5. The user selects one of the two holding grooves 51 of the movable mechanism 5. For example, when the user selects the first holding groove 51A, which is closer to the opening 8, of the two holding grooves 51, the lighting fixture body 2 and the light source device 3 can be installed so that the panel 31 and the lower surface 101 of the lighting fixture 1 are at the same height, as shown in FIG. 1A. Also, when the user selects the second holding groove 51B, which is closer to the grip 34, of the two holding grooves 51, the lighting fixture body 2 and the light source device 3 can be installed so that the panel 31 and the light source 30 are higher than the lower surface 101 of the lighting fixture 1, as shown in FIG. 1B. In either case, the user rotates the lighting fixture body 2 and the light source device 3 in the selected holding groove 51 until the protrusion 50 and the fixing protrusion 52 are fitted together. By fitting the protrusion 50 and the fixing protrusion 52 together, the rotation of the lighting fixture body 2 and the light source device 3 is suppressed, and positioning is completed. In this embodiment, it is described that the lighting fixture body 2 and the light source device 3 are inserted into the first holding groove 51A, which is closer to the opening 8, of the two holding grooves 51.

[0040] The user attaches the lighting fixture 1, in which the lighting fixture body 2 and light source device 3 are integrated, to a mounting part on the ceiling. First, the user connects the power input part 40 of the light source device 3 to a lead wire of a commercial power source located in the ceiling space or the like. By connecting the commercial power source to the power input part 40, it becomes possible to supply power to the lighting fixture 1. Next, the user hooks the mounting spring 22 onto the mounting part on the ceiling and pushes the lighting fixture 1 into the mounting part. In this way, the mounting spring 22 returns to its original position, and the ceiling board is sandwiched between the mounting spring 22 and the flange 6, completing the installation of the lighting fixture 1.

[0041] Next, removal of the lighting fixture 1 will be described. When removing the lighting fixture 1 from its mounting part on the ceiling, the user pulls the flange 6 toward the floor surface, which releases the mounting spring 22 and allows the lighting fixture 1 to be removed from the mounting part. Since the lighting fixture 1 is connected to the commercial power source, the connection between the power input unit 40 and the lead wire connected to the commercial power source is released. In this manner, the lighting fixture 1 can be removed from its mounting part on the ceiling.

[0042] In the removed lighting fixture 1, the lighting fixture body 2 and the light source device 3 remain connected, so when replacing either of them, the user needs to separate the lighting fixture body 2 and the light source device 3. Next, a case where the lighting fixture body 2 and the light source device 3 are separated will be described. Since the protrusion 50 and the fixing protrusion 52 are engaged with each other, the user can grasp the gripping portion 34 and rotate the lighting fixture body 2 and the light source device 3 in the opposite direction to the attachment, thereby releasing the engagement between the protrusion 50 and the fixing protrusion 52, and the lighting fixture body 2 and the light source device 3 can be rotated. When the lighting fixture body 2 and the light source device 3 are rotated in the opposite direction to the attachment, the protrusion 50 passes through the vertical cut of the movable mechanism 5. Since the first holding groove 51A and the sliding portion 25 are at the same height from the bottom surface 101 of the lighting fixture 1, the protrusion 50 slides on the sliding portion 25 and hits the insertion portion 23 by continuing to rotate the lighting fixture body 2 and the light source device 3. When the user reaches the insertion portion 23, while still holding the grip portion 34, the light source device 3 is pushed out toward the lighting fixture body 2, and the lighting fixture body 2 and the light source device 3 are separated. In this manner, the user can remove the lighting fixture 1 from the mounting portion on the ceiling.

[0043] The lighting fixture 1 of this embodiment is characterized in that the user can change the height of the panel 31 and light source 30 of the lighting fixture 1. Next, a case where the height of the panel 31 and light source 30 of the lighting fixture 1 is changed will be described. The height of the panel 31 and light source 30 of the lighting fixture 1 can be changed by switching the holding groove 51 of the movable mechanism 5 from the first holding groove 51A to the second holding groove 51B.

[0044] In a state where the lighting fixture body 2 and the light source device 3 are separated, the user integrates the lighting fixture body 2 and the light source device 3. The contents of inserting the protrusion 50 into the insertion portion 23 and sliding the protrusion 50 along the sliding portion 25 are the same as those described above. Next, when the protrusion 50 reaches the movable mechanism 5, the user slides the protrusion 50 along the vertical groove 53 of the movable mechanism 5 so as to select the second holding groove 51B of the movable mechanism 5, and then selects the second holding groove 51B. In a state where the second holding groove 51B is selected, the user further rotates the lighting fixture body 2 and the light source device 3. The protrusion 50 fits into the second fixing protrusion 52B, and the lighting fixture body 2 and the light source device 3 fit together and do not rotate. In this state, when the user attaches the lighting fixture 1 to the mounting portion of the ceiling, the height of the panel 31 and the light source is changed with respect to the lower surface 101 of the lighting fixture 1.

[0045] The height of the panel 31 and the light source 30 has been changed in the above description with the lighting fixture body 2 and the light source device 3 separated. However, the height of the panel 31 and the light source 30 may be changed with the lighting fixture body 2 and the light source device 3 integrated. That is, the lighting fixture 1 may be removed from the mounting part on the ceiling, the second holding groove 51B may be reselected from the first holding groove 51A, and the lighting fixture 1 may be reattached to the mounting part on the ceiling. In this case, the user who removed the lighting fixture 1 from the mounting part on the ceiling grasps the cross-shaped gripping part 34 and rotates the lighting fixture body 2 and the light source device 3 in a direction opposite to the direction when the lighting fixture 1 was attached from the first holding groove 51A, thereby releasing the engagement between the protrusion 50 and the first fixing protrusion 52A. When the user rotates the protrusion 50 to the vertical groove 53 of the movable mechanism 5, the user moves the protrusion 50 in the vertical direction of the movable mechanism 5 (the height direction of the lighting fixture 1). When the protrusion 50 is aligned with the height of the second holding groove 51B, the lighting fixture body 2 and the light source device 3 are rotated so that the protrusion 50 slides in the direction of the dead end of the second holding groove 51B. When rotated to the dead end of the second holding groove 51B, the protrusion 50 fits into the second fixing protrusion 52B, and the lighting fixture body 2 and the light source device 3 are fixed. In this state, the user can change the height of the panel 31 and the light source 30 by attaching the lighting fixture 1 to a mounting part on the ceiling without separating the lighting fixture body 2 and the light source device 3 (see FIG. 1B).

[0046] (4) Advantages The lighting fixture 1 of this embodiment includes a light source device 3 and a lighting fixture body 2.
