In FIG. 4, the attachment member 50 and the power cable 55 are also illustrated. In the following description, the ceiling 60 side is described as the upper side, and the opposite side is described as the lower side. For example, the main light emission direction of the lighting fixture 10 is downward.

  The terminal block 20 is a member mainly made of an insulating material into which the end 55a of the power cable 55 drawn from the ceiling 60 (structure) is inserted. Specifically, the terminal block 20 is formed of resin, ceramic, or the like. The terminal block 20 covers one main surface 31 a of the power supply circuit unit 30 and is accommodated in the light emitting unit 40. The terminal block 20 and the light emitting unit 40 are fixed by three screws 41 inserted into the screw hole portions 25a, 25b, and 25c of the terminal block 20 from above (the positive side of the Z axis in the drawing). Is done. In FIG. 4, the structure of the terminal block 20 is illustrated in a simplified manner, and details of the structure of the terminal block 20 will be described later with reference to another drawing.

  The power supply circuit unit 30 includes a substrate 31 and a circuit component 32 mounted on the substrate 31, and converts AC power supplied from the power cable 55 into DC power for the light emitting unit 40 to emit light. The power supply circuit unit 30 is accommodated in a housing constituted by the terminal block 20 and the light emitting unit 40. Although not shown, the power supply circuit unit 30 and the light emitting unit 40 are electrically connected by a cable with a connector or the like.

  The substrate 31 is a substantially circular plate-like substrate with a part cut away, and is formed of, for example, resin. As the substrate 31, an alumina substrate, a metal base substrate, a ceramic substrate, or the like may be used. The circuit board 32 is mounted on both main surfaces of the substrate 31, and the connection pins 33 for receiving power from the power cable 55 are provided on the main surface 31 a facing the terminal block 20. The circuit component 32 may be mounted only on one main surface of the substrate 31.

  The power supply circuit unit 30 is held by the terminal block 20. A holding mechanism for the power supply circuit unit 30 of the terminal block 20 will be described later.

  The light emitting unit 40 is a light emitting unit using an LED provided therein as a light source. The LEDs in the light emitting unit 40 emit light using DC power supplied from the power supply circuit unit 30.

  Specifically, the light emitting unit 40 is a direct light emitting unit having a light guide plate, a reflecting plate, and the like in addition to the LED. The light emitting unit 40 may be a so-called edge light type light emitting unit.

  The upper side of the light emitting unit 40 (the + side of the Z axis) is a bottomed cylindrical housing portion 43. The accommodating portion 43 is formed of a metal such as aluminum die cast, for example, but may be composed of other materials.

  The terminal block 20 and the power supply circuit unit 30 are housed inside the housing portion 43. A boss 44 to which a screw 41 for fixing the terminal block 20 to the light emitting unit 40 is attached is provided inside the housing portion 43.

  On the outer peripheral surface of the accommodating portion 43, an annular outer flange portion 45 is provided along the circumferential direction. The outer flange portion 45 is fitted with an inner flange portion (not shown) provided on the inner peripheral surface of the mounting member 50 along the circumferential direction.

  The lower side of the light emitting unit 40 (the negative side of the Z axis) is covered with a translucent cover 42. The cover 42 is a dome-shaped optical member made of a translucent material such as silicone resin, acrylic resin, polycarbonate resin, or glass. The cover 42 may have light diffusibility by including light diffusing particles and the like. The cover 42 is provided with the above-described LED, light guide plate, reflector, and the like, and light emitted from the LED is taken out through the cover 42.

  The attachment member 50 is a bottomed cylindrical member having a circular flat bottom on the upper side and a cylindrical side. The attachment member 50 is formed of, for example, a metal material such as aluminum or iron, a ceramic, or a resin material having thermal conductivity.

  A circular opening 51 is formed at the center of the bottom of the mounting member 50. A power cable 55 drawn from the ceiling 60 is inserted into the opening 51.

  Further, a through hole 52 is formed at the bottom of the attachment member 50 so as to sandwich the opening 51 with a space therebetween. A wood screw 53 is inserted into the through hole 52 and the wood screw 53 is tightened, whereby the attachment member 50 is attached to the ceiling 60.

  An inner collar portion (not shown) is provided on the inner peripheral surface of the side portion of the attachment member 50. The inner flange projects inwardly in the vicinity of the center in the vertical direction, is formed in an annular shape, fits with the outer flange 45 of the lighting fixture 10 (light emitting unit 40), and holds the lighting fixture 10. For example, the inner collar part and the outer collar part 45 may be fitted by elastically deforming one or both of the housing part 43 and the mounting member 50, or the inner collar part and the outer collar part formed in a screw shape. 45 may be screwed together. Since the inner diameter of the mounting member 50 is larger than the outer diameter of the housing portion 43, the outer peripheral surface of the housing portion 43 is covered with the mounting member 50.

  The power cable 55 is an electric wire that is disposed on the back of the ceiling or the like and supplies commercial power to the lighting fixture 10 and other electric devices. The end portion 55a of the power cable 55 is configured by a pin made of metal such as copper having rigidity. The portions other than the end portion 55a have flexibility and are covered with an electrically insulating member such as resin.

[Detailed configuration of terminal block]
Next, the detailed configuration of the terminal block 20 (and the power supply circuit unit 30) will be described with reference to FIGS. 5 and 6 are perspective views of the terminal block 20 and the power supply circuit unit 30. FIG. FIG. 7 is a bottom view of the terminal block 20 and the power supply circuit unit 30 in an assembled state.

  As shown in FIGS. 5 and 6, the terminal block 20 has a substantially circular dome shape (the shape in plan view is a substantially circular shape), and is one main surface 31a of the substrate 31 (the main surface on the + side of the Z axis). ) And surrounds the side surface of the substrate 31. That is, the terminal block 20 accommodates the power supply circuit unit 30.

  More specifically, as shown in FIG. 7, the terminal block 20 is held in a state in which the power supply circuit unit 30 is accommodated by the four locking claws 27a, 27b, 27c, and 27d. The accommodation here means that most of the power supply circuit unit 30 is located in a space defined by the terminal block 20.

  According to the holding mechanism (holding portion) such as the locking claws 27a to 27d, the power supply circuit unit 30 can be attached to the terminal block 20 with one touch, so that there is an advantage that assembly is easy.

  In the lighting fixture shown in FIG. 1 and FIG. 2 described above, the terminal block is provided separately from the lighting fixture. On the other hand, in the lighting fixture 10, the terminal block 20 also functions as an outer casing of the power circuit unit 30. In other words, the outer casing of the power circuit unit 30 also functions as a terminal block. Thereby, since the number of parts is reduced, the lighting fixture 10 can be configured to be thin.

  By the way, although the edge part 55a of the power cable 55 is inserted in the terminal block 20, in the lighting fixture 10, the structure for inserting the power cable 55 in the terminal block 20 is also devised. Hereinafter, the structure for inserting the power cable 55 will be described in detail. 8 and 9 are exploded perspective views of the terminal block 20. FIG. 10 is an enlarged view of a terminal hole portion into which the end portion 55a of the power cable 55 is inserted.

  As shown in FIGS. 8 and 9, a recess 21 c is provided on the surface of the terminal block 20 that faces the ceiling 60. And as FIG. 10 shows, the edge part 55a of the power cable 55 is inserted in the terminal holes 28c and 28d provided in the side surface 21d (surface of the terminal block 20 which prescribes | regulates the side part of the recessed part 21c) of the recessed part 21c. Is done.

  The terminal block 20 includes two members, a first member 21 and a second member 22 provided with terminal holes 28c and 28d in order to store the connection terminals 23a and 23b therein. The terminal block 20 is provided with a release button 24.

  The connection terminals 23 a and 23 b are metal members for electrically connecting the power cable 55 and the power circuit unit 30 and supplying power from the power cable 55 to the power circuit unit 30. FIG. 11 is an enlarged view of the connection terminal 23a.

  The end 55a of the power cable 55 inserted into the terminal hole 28c is inserted into the first clamping portion 29a (gap) of the connection terminal 23a shown in FIG. Specifically, when the end portion 55a of the power cable 55 is pressed against the first clamping portion 29a, the leaf spring portion 29c (and the leaf spring portion 29d) moves in the Y-axis direction in FIG. The gap of the portion 29a is widened, and the end portion 55a of the power cable 55 is inserted into the first clamping portion 29a. And the edge part 55a of the power cable 55 is clamped by the 1st clamping part 29a by the urging | biasing force of the leaf | plate spring part 29c.

  On the other hand, when the end portion 55a is pulled out from the first clamping portion 29a, the release button 24 shown in FIG. 10 is used. Specifically, when the release button 24 is pushed, the leaf spring portion 29d shown in FIG. 11 is pushed in the Y-axis direction in FIG. As a result, the leaf spring portion 29c integrally formed with the leaf spring portion 29d also moves in the Y-axis negative direction to widen the gap between the first clamping portions 29a, and the end portion 55a can be pulled out.

  It is assumed that the release button 24 is pushed by the tip of the driver. Therefore, in order to ensure the strength near the release button 24, a thick portion 26 is provided in the vicinity of the release button 24 in the bottom surface 21e of the recess 21c (the surface of the terminal block 20 that defines the bottom of the recess 21c). ing. The thick portion 26 also functions as a mark indicating the position of the release button 24.

  On the other hand, the connection pin 33 is inserted into the second clamping part 29b in the second clamping part 29b of the connection terminal 23a. FIG. 12 is a partial cross-sectional view of the vicinity of the connection pin 33.

  As shown in FIG. 12, in a state where the terminal block 20 holds the power supply circuit unit 30, the connection pin 33 is inserted and held in the second holding portion 29b.

  As described above, in the terminal block 20, the terminal holes 28c and 28d are provided on the side surface 21d of the recess 21c provided on the surface facing the ceiling 60. That is, the insertion direction of the end portion 55a of the power cable 55 is a direction (Y-axis direction in the drawing) that intersects the thickness direction of the lighting fixture 10 (Z-axis direction in the drawing). According to such a configuration, it is not necessary to increase the holding mechanism (connection terminals 23a and 23b) of the end portion 55a in the thickness direction of the lighting fixture 10, so that the lighting fixture 10 can be thinned.

  In addition, the connection between the end portion 55a and the connection pin 33 and the connection terminal 23a is realized by simple insertion, which contributes to the thinning of the lighting fixture 10.

  The connection pin 33 and the connection terminal 23a are in elastic contact. For this reason, the position shift of the power supply circuit unit 30 can be absorbed in the contact part of the connection pin 33 and the connection terminal 23a, and contact reliability is improved.

  Further, in order to reduce the thickness of the terminal block 20, the power supply circuit unit 30 is devised in the arrangement of the circuit components 32 on the substrate 31. FIG. 13 is a diagram for explaining the arrangement of the circuit components 32 of the power supply circuit unit 30.

  A region 70 shown in FIG. 13 is a region corresponding to the bottom surface 21 e of the recess 21 c in the main surface 31 a of the power supply circuit unit 30. In other words, the region 70 is a region that overlaps the bottom surface 21e when the power supply circuit unit 30 held by the terminal block 20 is viewed in plan.

  Here, in the region 70, the low-profile component of the circuit component 32 is disposed, and in the peripheral region of the region 70, the high-profile component of the circuit component 32 is disposed. In other words, only the circuit component 32 having a height lower than the predetermined value is mounted in the region 70.

  Thus, in the lighting fixture 10, space is efficiently utilized by providing a low-profile part in the area | region corresponding to the bottom face 21e of the recessed part 21c. In other words, the luminaire 10 is thinned by reducing the gap between the terminal block 20 and the power supply circuit unit 30 as much as possible.

[Other features]
Next, the other characteristic structure of the lighting fixture 10 is demonstrated.

  As shown in FIGS. 8 and 9 described above, the second member 22 is slid into the first member 21. Specifically, the slide portion 22 a of the second member 22 is inserted into the groove 21 a of the first member 21, and the slide portion 22 b of the second member 22 is inserted into the groove 21 b of the first member 21.

  As described above, when the second member 22 is slidably inserted in the horizontal direction (Y axis + direction in the drawing) with respect to the first member 21, the second member 22 is slid with respect to the first member 21. And surface contact at 22b.

  In the configuration such as the terminal block 20, it is assumed that the second member 22 is often loaded in the vertical direction (Z-axis-direction in the drawing). For example, when the power cable 55 connected to the terminal block 20 is pulled in the vertical direction or when the release button 24 is erroneously pressed (when the second member 22 itself is accidentally opened), the second member is used. 22 is loaded in the vertical direction.

  On the other hand, the terminal block 20 can receive a load in the vertical direction by surface contact without increasing the number of members (without increasing the cost) due to the slide structure that is easy to assemble. Therefore, reducing the risk of the second member 22 falling off from the first member 21 or being damaged by the load on the second member 22 in the vertical direction (Z-axis direction in the figure). Can do.

  In addition, since the second member 22 is slid and inserted in the horizontal direction with respect to the first member 21, there is no need to provide an assembly mechanism that increases in the vertical direction. For this reason, the said slide insertion mechanism contributes to thickness reduction of the lighting fixture 10. FIG.

The second member 22 has a screw hole 25 a for fixing the terminal block 20 to the light emitting unit 40. Thereby, the second member 22 is screwed at the same time that the terminal block 20 is fixed to the light emitting unit 40, and a mechanism for regulating the horizontal movement (sliding direction) of the second member 22 relative to the first member 21 is separately provided. There is an advantage that it is not necessary to provide it. In other words, the screw hole portion 25 a is used for both fixing the terminal block 20 to the light emitting unit 40 and fixing the position of the second member 22 with respect to the first member 21.

Further, when the insertion of the second member 22 into the first member 21 is insufficient, the positions of the screw hole portion 25a and the boss 44 do not match, so the screw 41 cannot be inserted into the screw hole portion 25a. . Therefore, by providing the screw hole 25a in the second member 22, the user (installer of the lighting fixture 10) can be made aware that the insertion of the second member 22 is insufficient.

  Further, when the end portion 55a of the power cable 55 is inserted into the side surface 21d of the recess 21c as described above, the power cable 55 needs to be bent. FIG. 14 is a schematic cross-sectional view showing a bent state of the power cable 55. When the power cable 55 is bent as shown in FIG. 14, the bending reaction force of the power cable 55 is applied to the bottom surface 21e of the recess 21c.

  Such a bending reaction force becomes larger as the distance in the height direction (distance in the Z-axis direction) from the ceiling surface to the terminal holes 28c and 28d is shorter, that is, as the lighting fixture 10 is thinner. .

  Therefore, the terminal block 20 is provided on the bottom surface 21e that supports the power cable 55 having the end 55a inserted into the terminal holes 28c and 28d from the bottom surface 21e side of the recess 21c by contacting the power cable 55. Cable support portions 28a and 28b. FIG. 15 is a schematic cross-sectional view showing a bent state of the power cable 55 in the terminal block 20 provided with the cable support portions 28a and 28b.

  As shown in FIG. 15, in the terminal block 20, the cable support portions 28 a and 28 b have inner peripheral surfaces (inner peripheral surfaces 28 in FIG. 14) below the terminal holes 28 c and 28 d (the negative side of the Z axis). , And extended in the Y axis + direction. That is, the cable support portions 28 a and 28 b are integrally formed with the second member 22.

  Thereby, the area | region where the cable support parts 28a and 28b are provided becomes thick by providing two of the cable support parts 28a and 28b and the bottom face 21e (part which comprises the bottom face 21e of the terminal block 20) of the recessed part 21c. It becomes. That is, the region where the cable support portions 28a and 28b are provided is a region where the strength is improved, and in this region, the strength for receiving the bending reaction force of the power cable 55 that increases as the lighting fixture 10 becomes thinner is provided. Secured.

  Furthermore, according to the cable support portions 28a and 28b, there is also an effect that the positions of the terminal holes 28c and 28d when viewed from the ceiling 60 side (when viewed from the + side of the Z axis) are easily seen.

  In the terminal block 20, the cable support portions 28 a and 28 b are provided on the second member 22, but may be provided on the first member 21. The cable support portions 28a and 28b are provided continuously with the inner peripheral surface of the lower side of the terminal holes 28c and 28d (the negative side of the Z-axis), but the cable support portions 28a and 28b are connected to the terminal holes 28c and 28b. It may be provided separately from 28d.
