As described above, in the present embodiment, the pair of mounting brackets 31 face each other with the through hole 27 at the center and are arranged at positions equally spaced from the through hole 27. This is an example, and the mounting bracket is used. The 31 can be arranged at an arbitrary position in the longitudinal direction of the upper surface portion 22a of the main body unit 21.

As shown in FIG. 7, the mounting bracket 31 has an extending portion 32, a second engaged portion 33 arranged to face the extending portion 32, and a connecting portion 34. The connecting portion 34 has a substantially plate shape, and connects the extending portion 32 and the second engaged portion 33. A plurality of (two in this embodiment) through holes 35 are formed in the connecting portion 34. The mounting bracket 31 is attached to the recess 22 by screwing a screw toward the upper surface portion 22a of the recess 22 via the through hole 35.

The extending portion 32 is a portion extending from one end of the connecting portion 34 to the outside in the extending direction of the connecting portion 34, and has a hooking portion 36 and a first engaged portion 37. The hook portion 36 is a portion for hooking the hook portion 72 of the mounting spring 71. The first engaged portion 37 is a portion where the first engaging portion 72c of the mounting spring 71 is engaged.

The hook portion 36 has a substantially plate-like shape and a substantially U-shape in side view, and extends substantially vertically from one end of the connecting portion 34. The first engaged portion 37 has a substantially plate shape, and is formed by cutting up from the hook portion 36 to the outside of the connecting portion 34 in the extending direction. That is, the first engaged portion 37 is formed so as to project outward from one end in the extending direction of the connecting portion 34 from the upper edge of the substantially U-shaped through hole 38 formed in the hook portion 36. There is. The first engaged portion 37 has an overhanging portion 37a, a base portion 37b, and a bent portion 37c.

The second engaging portion 73 of the mounting spring 71 is engaged with the bent portion 33b.
The extending portion 32 and the second engaged portion 33 are connected by the connecting portion 34 only on the upper edge side, and the lower edge side is separated from each other. As a result, the tip end side of the second engaged portion 33 is a free end, and only the base end side is a fixed end, so that the elastic deformation of the second engaged portion 33 is not hindered. In addition, the mounting spring 71 of the present embodiment is easy to manufacture because it requires less material than the structure for connecting the lower edge side, the cost is reduced, and the processing is easy.

Further, FIG. 8 shows the mounting bracket 31A as a modification of the mounting bracket 31. The mounting bracket 31A is configured to further provide an inclined extending portion 39 having an inclined surface 39a at the tip portion on the side of the mounting bracket 31 facing the hooking portion 36 of the second engaged portion 33. With this configuration, when the light source unit 41 is attached to the main body unit 21, the second engaging portion 73 of the mounting spring 71 is brought into contact with the inclined surface 39a, so that the second engaging portion 73 is attached to the mounting bracket 31. The light source unit 41 can be guided to the regular position of the main body unit 21 by guiding to the second engaged portion 33 of the above.

As shown in FIG. 5, the light source unit 41 includes a base member 42 which is a mounting member, a light source unit (LED module substrate) 51, a power supply device 61 which is a power supply unit, a mounting spring 71, a shade 81, and a pair of end caps 91. Mainly prepare.

The base member 42 is a member that holds the light source unit (LED module substrate) 51 and the shade 81 on the irradiation surface side, and holds the power supply device 61 and the mounting spring 71 on the mounting surface side. The base member 42 is a long metal plate-shaped member. The base member 42 also has a heat dissipation function of absorbing the heat generated by the light source unit 51 and releasing it to the air outside the base member 42. The base member 42 is formed so that its longitudinal dimension and lateral dimension are slightly smaller than those of the recess 22 described above.

The light source mounting portion 42a is a portion to which the light source portion (LED module substrate) 51 is mounted. The light source mounting portion 42a is a rectangular plate-shaped portion in a plan view on the irradiation surface side (lower side) of the base member 42. Since the base member 42 also has a heat dissipation function of absorbing the heat generated by the light source portion 51 and releasing it to the air outside the base member 42, the light source mounting portion 42a to which the light source portion 51 is in contact with the light source portion 51 It is formed flat so that the contact area of the light source is wide.

The light source unit 51 is a portion that emits light toward the irradiation surface side of the luminaire 11. As shown in FIG. 6, the light source unit 51 is a module substrate. In the light source unit 51, a plurality of LEDs 53, which are point light sources in the longitudinal direction of the substrate 54, are arranged on the substrate in a substantially linear manner at equal intervals on a long substrate 54 processed into a flat plate shape (horizontally elongated shape). They are arranged side by side (see FIG. 16). The plurality of LEDs 53 are arranged substantially in the center in the lateral direction of the substrate 54. In this embodiment, a plurality of LED elements (surface mount type LED elements) are used as the light source, but the present invention is not limited to this, and a COB type light emitting module, an organic EL element, or the like may be used. The light source portion 51 is arranged in contact with the irradiation surface side of the light source mounting portion 42a, and is mounted by a mounting member such as a screw. The light source unit 51 is electrically connected to the power supply device 61 by a wiring 63.
The light source portion 51 may be attached to the light source mounting portion 42a via a heat conductive sheet (not shown) or thermal paste, whereby higher heat dissipation can be obtained.

As shown in FIG. 16, on the irradiation surface side of the substrate 54, a connector 64 to which the wiring 63 is electrically connected is provided at at least one end of the substrate 54 in the longitudinal direction. The connector 64 is for electrically connecting to and from the power supply device 61 via the wiring 63. By connecting the wiring 63 to the connector 64, the board 54 and the power supply device 61 are electrically connected. The connector 64 is arranged at a position different from that of the plurality of LEDs 53 in the lateral direction of the substrate 54. Specifically, as shown in FIG. 17, the connector 64 is provided at a position deviated from the center in the lateral direction (width direction) of the substrate 54.
In FIGS. 16 and 17, the vertical direction of the light source unit 41 and the power supply unit 51 is opposite to the vertical direction of the paper surface.

The power supply device 61 is a device for supplying power to the LED 53 included in the light source unit 51 via the wiring 63 to light the LED 53. The power supply device 61 contains a power supply circuit in which a plurality of electronic components are mounted on a printed wiring board processed into a rectangular shape in a box-shaped power supply case. The power supply device 61 is arranged near the center in the longitudinal direction of the base member 42 on the mounting surface side of the light source mounting portion 42a. The power supply device 61 converts an alternating current supplied from an external power source into a predetermined direct current, and supplies the converted current to a plurality of LEDs 53 mounted on the substrate 54. The power supply device 61 is electrically connected to the terminal block 62 of the main body unit 21 via wiring (not shown).

As shown in FIG. 5, the power supply device 61 is arranged at a position facing the through hole 27 of the light source mounting portion 42a. The power supply device 61 includes an inclined surface 61a at one end of the upper surface of the power supply case. The inclined surface 61a faces the through hole 27 when the light source unit 41 is attached to the main body unit 21. Since the power supply device 61 is provided with the inclined surface 61a, a large space between the through hole 27 and the power supply device 61 can be secured when the light source unit 41 is attached to the main body unit 21, so that the light source unit 41 is inserted through the through hole 27. It is possible to prevent a sharp bending of the power supply line of an external power supply, and it is possible to prevent damage to the coating of the power supply line or disconnection.

When the lighting fixture 11 is attached to the ceiling surface C, the power supply line of the external power source is pulled out from the through hole 27, and the main body unit 21 is fixed to the ceiling surface C. The power supply device 61 is electrically connected to an external power supply by connecting the power supply line to the terminal block 62. The power supply unit 61 and the light source unit 51 are electrically connected by wiring.

The mounting spring 71 can be attached to and detached from the mounting bracket 31 of the main body unit 21. The mounting spring 71 is a metal member having a substantially rectangular shape (substantially U-shaped) in cross section and having elasticity (see FIG. 9). The mounting spring 71 is, for example, a metal leaf spring. The mounting spring 71 is mounted on the mounting surface side of the light source mounting portion 42a. The mounting spring 71 faces the central portion in the longitudinal direction of the light source mounting portion 42a on the mounting surface side in the center, and is arranged at a position equally spaced from the central portion. That is, the mounting spring 71 is arranged at a position corresponding to the mounting bracket 31 of the main body unit 21.

As shown in FIG. 9, the mounting spring 71 has a hook portion 72, a second engaging portion 73 arranged to face the hook portion 72, and a connecting portion 74. The connecting portion 74 has a substantially plate shape, and connects the hook portion 72 and the second engaging portion 73. A plurality of (two in this embodiment) through holes 75 for screwing are formed in the connecting portion 74. The mounting spring 71 is mounted on the mounting surface side of the light source unit 41 by screwing a screw from the mounting surface side of the light source mounting portion 42a via the through hole 75.

Further, a through hole 76 is formed in the connecting portion 74 at an arbitrary position. The through hole 76 prevents the tip of the screw that penetrates the light source mounting portion 42a and protrudes toward the mounting surface from interfering with the connecting portion 74 when the substrate 54 is fixed to the light source mounting portion (chassis) 42a with screws. Is for.

Further, as shown in FIG. 9, the connecting portion 74 of the mounting spring 71 has a holding portion 77 that is convex toward the upper side (mounting surface side) and has a rectangular shape in a side view. The holding portion 77 holds, for example, the wiring 63, which is the secondary wiring extending from the power supply device 61 to the substrate 54 on which the plurality of LEDs 53 are mounted, along the irradiation side surface of the light source mounting portion 42a (FIG. 18 (a). )reference). As a result, when the wiring 63 is fixed to the base member 42, it is only necessary to pass the wiring 63 through the holding portion 77 of the mounting spring 71 and hold the wiring 63, so that the work of fixing the wiring 63 can be easily performed. Further, since the position of the wiring 63 can be fixed along the base member 42, it is possible to prevent the wiring 63 from floating from the base member 42 and reduce the risk of disconnection due to being caught. As an example of reducing the risk of disconnection, when the light source unit 41 is mounted on the main body unit 21, the disconnection due to the wiring 63 being sandwiched between the light source unit 41 and the main body unit 21 can be prevented. Further, when the light source unit 41 is removed from the main body unit 21, it is possible to prevent the wiring 63 from being caught by the mounting bracket 31 or the like of the main body unit 21. Further, when the mounting spring 71 is mounted on the base member 42, the wiring 63 can be fixed at the same time, so that the assembling workability of the lighting fixture 11 is improved.
The shape of the holding portion 77 may be any shape as long as the wiring 63 can be held, and may be a shape other than the rectangular shape in the side view. The shape of the holding portion 77 may be, for example, a semicircular shape, a semi-elliptical shape, a triangular shape, or the like.

Further, it is preferable that the height dimension and the width dimension of the holding portion 77 are slightly larger than the thickness (outer diameter) of the wiring 63. As a result, continuous pressing force is not applied to the wiring 63, so that damage to the coating of the wiring 63 can be prevented. That is, when the size of the holding portion 77 is smaller than that of the wiring 63, the pressing force is continuously applied to the wiring 63, and there is a risk of coating damage.

The holding portion 77 is provided at a position closer to the end portion of the substrate 54 in the lateral direction than the plurality of LEDs 53 in the lateral direction (width direction) of the substrate 54. The holding portion 77 is provided at a position deviated from the plurality of LEDs 53 in the lateral direction (width direction) of the substrate 54. Specifically, the plurality of LEDs 53 are arranged along the longitudinal direction of the substrate 54 at the center in the lateral direction (width direction) of the substrate 54. That is, the plurality of LEDs 53 are arranged along the CC line in FIG. 18A. On the other hand, the holding portion 77 is provided at a position deviated from the center (CC line) in the width direction of the mounting spring 71. As a result, the wiring 63 arranged on the mounting surface side of the base member and the plurality of LEDs 53 arranged on the substrate 54 can be prevented from overlapping, so that the heat generated by the LED 53 is wired via the base member 42. It can be difficult to transmit to 63. As a result, deterioration of the wiring 63 due to heat can be prevented.
The position of the LED 53 on the substrate 54 in the width direction is not limited to the center, and may be a position closer to the end portion in the width direction. At that time, it is preferable that the eccentric directions are different from each other so that the width direction position of the LED 53 and the width direction position of the wiring 63 do not overlap on the front and back sides (irradiation surface side and mounting surface side).

As described above, the substrate 54 is provided with a connector 64 to which the wiring 63 is electrically connected to at least one end of the substrate 54 in the longitudinal direction. The connector 64 is arranged at a position different from the position where the plurality of LEDs 53 are arranged in the lateral direction of the substrate 54. Further, the holding portion 77 is provided at a position corresponding to the connector 64 in the lateral direction of the substrate 54. That is, by setting the positions of the holding portion 77 and the connector 64 at the same position in the lateral direction of the board 54, the wiring 63 arranged between the holding portion 77 and the connector 64 is substantially along the longitudinal direction of the board 54. It becomes a straight line.
In this way, by arranging the connector 64 at a position different from the plurality of LEDs 53 in the lateral direction of the substrate 54, the LED 53 can be arranged up to the end in the longitudinal direction of the substrate 54, so that the end in the longitudinal direction of the light source unit 41 can be arranged. The amount of light in the section can be secured. Further, when the connector 64 is provided at the end of the board 54 (the end of the LED row) in which the LEDs 53 are arranged side by side, the distance between the LED 53 arranged at the end and the connector 64 is short, so that the connector 64 Is likely to enter the light distribution range of the LED 53 (for example, a light distribution angle of 120 degrees), the connector 64 may block the light emitted by the adjacent LED 53, and a shadow may be cast on the shade 81. In the present embodiment, the connector 64 is not provided at the end of the LED row, and the connector 64 is arranged at a position deviated from the LED row in the width direction. Therefore, the distance between the LED 53 and the connector 64 can be increased. It becomes difficult for 64 to enter the light distribution range of the LED 53 (for example, a light distribution angle of 120 degrees), and there is little possibility that a shadow is formed on the shade 81. Further, since the holding portion 77 is provided at a position corresponding to the connector 64, the wiring 63 is not bent at a steep angle and arranged, so that the risk of disconnection of the wiring 63 can be reduced.
In the present embodiment, a plurality of LEDs 53 are arranged in one row in the center in the lateral direction (width direction) of the substrate 54, but for example, a plurality of rows (two rows) are arranged at arbitrary positions in the width direction of the substrate 54. 3 rows, etc.) LED 53 may be arranged side by side. In this case, the center thereof is the center in the width direction of the plurality of rows of LEDs 53.

The hook portion 72 is a portion to be hooked on the hook portion 36 of the mounting bracket 31 of the main body unit 21. The hook portion 72 is for temporarily suspending the light source unit 41 with respect to the main body unit 21 by hooking the hook portion 72 on the hook portion 36.
Here, the "temporary suspension" means, for example, a state in which the light source unit 41 is temporarily suspended from the main body unit 21 by wiring connection or repair inspection when the light source unit is attached to the main body unit 21.

The hook portion 72 has a side view hook shape, and has a base portion 72a, a curved portion 72b, and a first engaging portion 72c. The base portion 72a has a substantially plate shape and extends substantially vertically from one end of the connecting portion 74. The curved portion 72b is a plate-shaped portion extending from the tip end portion of the base portion 72a and curved in a side view arc shape. The first engaging portion 72c has a curved plate shape, and has a substantially V-shaped cross-sectional view extending from the tip portion of the curved portion 72b and projecting toward the base portion 72a facing the first engaging portion 72c. It is a part. The first engaging portion 72c has a substantially plate-shaped inclined surface 72d whose tip portion extends diagonally downward toward the extending portion 32 side, and a direction extending from the tip portion and away from the base portion 72a. It has a substantially plate-shaped inclined surface 72e extending diagonally downward toward the surface. The first engaging portion 72c engages with the first engaged portion 37 (bending portion 37c) of the mounting bracket 31.

When the first engaging portion 72c of the hook portion 72 is engaged with the first engaged portion 37, the inclined surface 72d of the first engaging portion 72c becomes the inclined surface 37d of the first engaged portion 37. Upon contact, the downward movement of the mounting spring 71 is restricted. Similarly, when the second engaging portion 73 is engaged with the second engaged portion 33, the inclined surface 73c of the second engaging portion 73 comes into contact with the inclined surface 33c of the second engaged portion 33. Therefore, the downward movement of the mounting spring 71 is restricted.

Further, as shown in FIG. 7 (c), the length dimension (width dimension) between the inner tip portion of the inclined surface 33c and the inner tip portion of the inclined surface 37d in the mounting bracket 31 is L2. That is, the length dimension L2 is the dimension of the portion having the shortest distance between the second engaged portion 33 and the first engaged portion 37. As shown in FIG. 9 (c), the length dimension (width dimension) between the middle portion of the curved portion 73b described later and the tip portion of the curved portion 72b in the mounting spring 71 is L1, and the tip portion of the base portion 73a described later. Let L3 be the length dimension (width dimension) between the surface and the inner tip portion of the inclined surface 72d. That is, the length dimension L1 is the dimension of the portion having the longest distance between the hook portion 72 and the second engaging portion 73. The length dimension L3 is the dimension of the portion having the shortest distance between the first engaging portion 72c and the second engaging portion 73. In each of the dimensions of L1, L2, and L3, the mounting spring 71 engages with the mounting bracket 31 by satisfying the condition of L3 <L2 <L1.

Further, as shown in FIG. 9 (c), the width dimension between the inclined surface 72e of the first engaging portion 72c and the tip end portion of the base portion 72a is L4, and as shown in FIG. 7 (c), the hooking portion. Let L5 be the thickness dimension of 36. By setting L5 <L4 in each of the dimensions of L4 and L5, the hook portion 36 can be hooked on the hook portion 72.

The second engaging portion 73 has a base portion 73a and a curved portion 73b. The base portion 73a has a substantially plate shape and extends substantially vertically from the other end of the connecting portion 74. The curved portion 73b is a plate-shaped portion having a substantially arc-shaped side view extending from the tip end portion of the base portion 73a and projecting toward the opposite side of the hook portion 72 facing the second engaging portion 73. The second engaging portion 73 engages with the second engaged portion 33 of the mounting bracket 31.

The shade 81 is attached so as to cover the irradiation surface side of the light source portion 51 attached to the light source attachment portion 42a, and transmits and diffuses the light from the light source portion 51 to form an emission surface. The shade 81 is a long member having a substantially arcuate cross-sectional view. The total length in the longitudinal direction of the shade 81 is substantially the same as the total length in the longitudinal direction of the base member 42. The shade 81 is formed of a translucent (for example, milky white) acrylic resin material having translucency.
The shape of the shade is not limited to the shape of the present embodiment. For example, the cross-sectional shape of the shade can be configured as a semicircular cross-section, a square cross-section, or a trapezoidal cross-section.

As shown in FIG. 16, the pair of end caps 91 are attached to both ends of the shade 81 in the longitudinal direction. The pair of end caps 91 close the pair of openings formed at the pair of longitudinal ends of the shade 81. The end cap 91 is made of the same material as the shade 81. The end cap 91 may be made of a material different from that of the shade 81. Note that FIGS. 18 to 21 show one end cap 91 of the pair of end caps 91, but the configuration of the other end cap 91 is the same as the configuration of one end cap 91. The explanation is omitted.

As shown in FIGS. 19 and 20, the end cap 91 has a base portion 92, an extension portion 93, and a guide portion 94. The base portion 92 is bottomed and covers the openings at both ends of the shade 81 in the longitudinal direction. The extending portion 93 has a flat plate shape and extends in a direction substantially orthogonal to both end faces in the longitudinal direction of the shade 81. The extending portion 93 extends from the upper end of the base portion 92 so as to cover the upper surface of the longitudinal end portion of the light source mounting portion 42a. The guide portion 94 is provided so as to project upward from the upper surface of the extending portion 93.

The guide portion 94 connects a pair of side wall portions 94a extending upward in a substantially trapezoidal shape of a side view, an inclined surface portion 94b connecting the back surface side of the pair of side wall portions 94a, and the upper surface side of the pair of side wall portions 94a. It has a top surface portion 94c and. When the end cap 91 covers the openings at both ends in the longitudinal direction of the shade 81 to which the base member 42 is assembled, the guide portion 94 forms a space S in which the wiring 63 can be arranged (see FIG. 21). The space S is a space surrounded by the side wall portion 94a, the inclined surface portion 94b, and the top surface portion 94c.

As shown in FIG. 5, the pair of end caps 91 are attached to both ends of the shade 81 in the longitudinal direction. The pair of end caps 91 close the pair of openings formed at the pair of longitudinal ends of the shade 81. Further, in the luminaire 11 in which the light source unit 41 is attached to the main body unit 21, the end cap 91 is in a state of being locked by the end member 26. Further, as shown in FIG. 6, in the luminaire 11, a part of both ends of the shade 81 in the lateral direction is housed in the recess 22. The end cap 91 is made of the same material as the shade 81. The end cap 91 may be made of a material different from that of the shade 81.

Next, a procedure for attaching the light source unit 41 to the main body unit 21 will be described with reference to FIGS. 10 to 13.
First, when the operator attaches the light source unit 41 to the main body unit 21 fixed to the ceiling surface C from below the main body unit 21 (see FIG. 10), the operator attaches the tip of the hook portion 72 of the mounting spring 71 of the light source unit 41. (The first engaging portion 72c) is inserted into the through hole 38 of the mounting bracket 31 of the main body unit 21 and the hook portion 72 is hooked on the hook portion 36 (see FIG. 11). In this case, the light source unit 41 is suspended below the main body unit 21 in a state of being inclined so that the second engaging portion 73 side of the mounting spring 71 is on the lower side (this state is referred to as a temporary suspension state).

When the light source unit 41 is temporarily suspended as shown in FIG. 11, the position of the light source unit 41 is stable even if the operator does not support the light source unit 41 by hand. Therefore, for example, the operator uses both hands to power the external power supply. The work of connecting the wire to the terminal block 62 can be performed. The terminal block 62 is provided with a connection terminal having a gap thinner than the thickness of the power supply line so that the power supply line after connection cannot be easily disconnected so that the terminal block 62 cannot be connected unless the power supply line is inserted with a relatively strong force. Often configured. Therefore, the operator often uses both hands to connect the power supply line to the terminal block 62. By temporarily suspending the light source unit 41 in this way, the operator can perform the installation work and the electrical connection work of the light source unit 41 by himself / herself. On the other hand, in the case of a lighting fixture that cannot temporarily suspend the light source unit, one worker holds the light source unit by hand and supports it so that it does not fall, while the other worker uses both hands to turn on the power line. Since the work of connecting to the terminal block must be performed, at least two workers are required, and the work efficiency is not good.

Next, as shown in FIG. 12, the operator lifts the second engaging portion 73 side of the mounting spring 71 of the light source unit 41 to bring the light source unit 41 into a substantially horizontal state. Then, while keeping the light source unit 41 in a substantially horizontal state, the light source unit 41 is pushed upward toward the main body unit 21. Then, the operator engages the first engaging portion 72c of the mounting spring 71 with the first engaged portion 37 of the mounting bracket 31, and engages the second engaging portion 73 of the mounting spring 71 with the first engaging portion of the mounting bracket 31. 2 Engage with the engaged portion 33. That is, the first engaging portion 72c and the second engaging portion 73 engage with the first engaged portion 37 and the second engaged portion 33 by moving the light source unit 41 upward. Specifically, immediately before the first engaging portion 72c and the second engaging portion 73 engage with the first engaged portion 37 and the second engaged portion 33, the curved portion 73b abuts on the bent portion 33b. , The curved portion 72b comes into contact with the bent portion 37c. By raising the light source unit 41 from the contact state, the curved portion 73b moves along the bent portion 33b, and the second engaging portion 73 is elastically deformed inward (on the hook portion 72 side). Similarly, the curved portion 72b moves along the bent portion 37c, and the hook portion 72 is elastically deformed inward (toward the second engaging portion 73). When the curved portion 73b gets over the V-shaped portion of the bent portion 33b, the second engaging portion 73 returns to the original shape, and the inclined surface 73c comes into contact with the inclined surface 33c. Similarly, when the curved portion 72b gets over the V-shaped portion of the bent portion 37c, the hook portion 72 returns to the original shape, and the inclined surface 72d comes into contact with the inclined surface 37d. As a result, the light source unit 41 is attached to the recess 22 with its upper end side housed in the recess 22 (see FIG. 13).

As described above, the curved portion 73b abuts on the bent portion 33b immediately before the first engaged portion 72c and the second engaged portion 73 engage with the first engaged portion 37 and the second engaged portion 33. , The curved portion 72b comes into contact with the bent portion 37c. At this time, the curved curved portion 73b is in line contact with the inclined surface 33d (see FIG. 12) of the bent portion 33b, and the curved curved portion 72b is in line contact with the inclined surface 37e (see FIG. 12) of the bent portion 37c. do. As a result, for example, friction is less than in the case where the surfaces are in surface contact with each other, and the engagement can be performed smoothly. Further, since the curved curved portion 72b and the curved portion 73b are formed in a curved shape (convex curved surface shape), the curved portion 37e and the inclined surface 33d are slightly in the lateral direction of the light source unit 41. Even if it moves, the curved portion 72b and the curved portion 73b are received by the inclined surface 37e and the inclined surface 33d. That is, even if the operator holds the light source unit 41 and the hand shakes a little and the light source unit 41 moves in the lateral direction, it is allowed within a predetermined range, and the mounting spring 71 is engaged with the mounting bracket 31. Can be matched.
The term "line contact" includes not only the case where the contact is made exactly linearly, but also the case where the contact is substantially linear although the width is predetermined.

Further, when the main body unit 21 and the light source unit 41 are in the state shown in FIG. 13, the inclined surface 72d is in contact with the inclined surface 37d, and the inclined surface 73c is in contact with the inclined surface 33c. Further, in the state shown in FIG. 13, the curved portion 72b cannot get over the V-shaped portion of the bent portion 37c due to the weight of the light source unit 41, and the hook portion 72 is inward (on the side of the second engaging portion 73). Does not elastically deform. Similarly, the curved portion 73b cannot get over the V-shaped portion of the bent portion 33b, and the second engaging portion 73 does not elastically deform inward (on the hook portion 72 side). As a result, the mounting spring 71 does not come off from the mounting bracket 31 only by the weight of the light source unit 41, and the light source unit 41 is stably held by the main body unit 21.

Further, when the light source unit 41 is removed from the main body unit 21, the operator grips both ends of the light source unit 41 (sade 81) shown in FIG. 13 in the lateral direction and pulls them downward (to separate them). By pulling out, the first engaged portion 72c and the second engaged portion 73 can be disengaged from the first engaged portion 37 and the second engaged portion 33, respectively, to disengage the engagement. Specifically, by applying a force so that the operator pulls out the light source unit 41 (sade 81) downward, the inclined surface 73c gets over the V-shaped portion of the bent portion 33b, and the second engaging portion 73 Elastically deforms inward (hook portion 72 side). Similarly, the curved portion 72b gets over the V-shaped portion of the bent portion 37c, and the hook portion 72 is elastically deformed inward (toward the second engaging portion 73). In this way, when the light source unit 41 is moved downward from the engaged state shown in FIG. 13, the mounting spring 71 is elastically deformed, and the engaged state between the mounting spring 71 and the mounting bracket 31 is disengaged.

When the mounting spring 71 and the mounting bracket 31 are disengaged from each other, the mounting spring 71 returns from the elastically deformed state to the original shape, and the hook portion 72 penetrates the through hole 38. Specifically, the base portion 72a side of the mounting spring 71 is located inside the extending portion 32 (the side facing the second engaged portion 33), and the first engaging portion 72c side of the mounting spring 71 is the extending portion 32. It is in a state of being located on the outside of (the side opposite to the side facing the second engaged portion 33).
Then, when the light source unit 41 is further lowered, the hook portion 36 enters the inner peripheral side of the curved portion 72b, and the hook portion 72 is in a state of being hooked on the hook portion 36.

When the light source unit 41 is moved downward in this way, the hook portion 72 is hooked on the hook portion 36 as shown in FIG. 12, and the light source unit 41 is temporarily suspended from the main body unit 21 as shown in FIG. It becomes a state. After that, as shown in FIG. 10, the hook portion 72 can be removed from the hook portion 36, and the light source unit 41 can be removed from the main body unit 21. With such a configuration, when the operator removes the light source unit 41 from the main body unit 21, even if the light source unit 41 is accidentally dropped after the mounting spring 71 and the mounting bracket 31 are disengaged, the hook portion 72 is hooked. It is possible to prevent the light source unit 41 from falling to the ground due to being caught by the 36 and temporarily suspended. Further, since the light source unit 41 can be temporarily suspended in this way, wiring work and repair / inspection work can be easily performed.

As shown in FIG. 9C, the curved portion 72b of the hook portion 72 has a curved inner peripheral surface and has a space S1 having a substantially circular side view. For example, when the light source unit 41 is removed from the main body unit 21, even if the light source unit 41 is accidentally dropped after the mounting spring 71 and the mounting bracket 31 are disengaged, the hook portion 36 of the mounting bracket 31 collides with the space S1. While being able to absorb the bounce at the time of falling, the curved portion 72b is configured to be hard to come off from the hooking portion 36. For example, when the space S1 is a narrow space having an elongated shape in a side view, the hook portion 36 cannot move in the lateral direction (width direction) of the light source unit 41, and the light source unit 41 bounces when dropped. It becomes difficult to absorb and easily comes off from the hooking portion 36.

The mounting spring 71 has a hook portion 72 and a second engaging portion 73, but both ends of the connecting portion 74 are fixed ends, and the upper ends of the hook portion 72 and the second engaging portion 73 are free. It constitutes a cantilever spring at the end. Since the hook portion 72 is formed so that the base portion 72a and the first engaging portion 72c face each other via the curved portion 72b, the bending rigidity (difficulty of bending) of the leaf spring is increased from the second engaging portion 73. growing. That is, the hook portion 72 is configured to require more force to bend than the second engaging portion 73 as a leaf spring. With this configuration, when the mounting spring 71 is engaged with the mounting bracket 31, the second engaging portion 73 having a bending rigidity smaller than that of the hook portion 72 comes into contact with the bent portion 33b and begins to bend first, and then continues. The hook portion 72 (curved portion 72b) abuts on the bent portion 37c and begins to bend. By configuring the hook portion 72 of the mounting spring 71 and the second engaging portion 73 to have different bending rigidity in this way, a large force is applied when the operator engages the mounting spring 71 with the mounting bracket 31. do not need. Further, when the mounting spring 71 is engaged with the mounting bracket 31, the first engaging portion 72c of the hook portion 72 is firmly bent by the relatively large bending rigidity of the hook portion 72, and the bent portion 37c of the first engaged portion 37 is engaged. The mounting spring 71 is hard to come off from the mounting bracket 31, and the light source unit 41 is stably held by the main body unit 21.

As shown in FIG. 10, the mounting bracket 31 may be configured so that its tip 36a fits in the recess 22 of the main body unit 21. That is, the mounting bracket 31 may be configured such that the height dimension H1 (see FIG. 7) in the vertical direction thereof is smaller than the height dimension (depth dimension) D of the recess 22. As a result, since the mounting bracket 31 does not protrude outward from the recess 22 of the main body unit 21, the possibility that the mounting bracket 31 will come into contact with the surroundings and be damaged or that rattling will occur during transportation of the main body unit 21 is reduced. Can be done. Further, the main body unit 21 can be compactly configured, and space saving when packing the main body unit 21 can be achieved.
Further, as shown in FIG. 10, the mounting spring 71 may be configured such that the height dimension H2 in the vertical direction thereof is smaller than the height dimension H3 of the power supply device 61. As a result, the light source unit 41 can be compactly configured, and space saving when packing the light source unit 41 can be achieved.

The mounting bracket 31 or the mounting spring 71 according to the present embodiment may be divided (see FIGS. 22 and 23) or separable at the middle portion (for example, the central portion) of the connecting portions 34 and 74, respectively. Thereby, for example, even when the dimension (width dimension) in the lateral direction of the light source unit 41 is changed, the divided mounting bracket 31 or the mounting spring 71 can be appropriately arranged according to the width dimension. ..

The mounting spring 71 may be configured to have a pair of hook portions 72 by providing a hook portion 72 instead of the second engaging portion 73 regardless of whether the mounting spring 71 is integrated or separated. .. As a result, the left and right sides of the mounting spring can be shared, so that the operator does not mistake the mounting direction of the mounting spring.

Further, in the present embodiment, the mounting spring 71 is attached to the light source unit 41 and the mounting bracket 31 is attached to the main body unit 21. For example, the mounting bracket 31 is attached to the light source unit 41 side and attached to the main body unit 21 side. It may be configured to attach the spring 71.

As described above, the mounting bracket 31 of the present embodiment faces the through hole 27 provided in the center of the upper surface portion 22a of the main body unit 21 in the longitudinal direction at the center, and is arranged at a position equally spaced from the through hole 27. Will be done. Similarly, the mounting spring 71 is also arranged at positions equally spaced from the central portion of the light source unit 41. However, the mounting positions of the mounting bracket 31 and the corresponding mounting spring 71 are not particularly limited. For example, the mounting positions of the pair of mounting brackets 31 and the pair of mounting springs 71 are arranged at asymmetrical positions in the longitudinal direction, not at equal intervals from the center of the main body unit 21 and the light source unit 41 of the lighting fixture 11. May be. With such a configuration, it is possible to prevent an operator from mistakenly mounting the light source unit 41 with respect to the main body unit 41.

Further, for example, as a modification of the mounting spring 71 of the present embodiment, as in the mounting spring 71A shown in FIG. 14, the positions of the connecting portions 74 of the through holes 75 and 75 for screwing are different in the longitudinal direction. It may be arranged in an asymmetrical position. That is, when the mounting spring 71 is rotated 180 degrees around the center C of the connecting portion 74, the through holes 75 and 75 may be arranged at positions where the positions of the through holes 75 and 75 are not rotationally symmetric. With such a configuration, it is possible to prevent the operator from mounting the mounting spring 71 and the mounting bracket 31 on the base member 42 in the wrong mounting direction.

Further, in the present embodiment, the position of the through hole 75 for fixing the screw of the mounting spring 71, that is, the position of the screw is configured so as not to overlap with the position of the substrate 54 of the light source unit (LED module substrate) 51. As a result, even if the screw for fixing the mounting spring 71 penetrates the base member 42, it is possible to prevent the screw from interfering with the substrate 54. By preventing the screws from interfering with the substrate 54, the substrate 54 is damaged at the tip of the screws, or the substrate 54 is lifted by the screws to reduce the contact area between the substrate 54 and the base member 42, and the light source portion 51 It is possible to prevent the heat dissipation from being lowered.

Further, as shown in FIG. 15, instead of the mounting bracket 31 of the present embodiment, a portion for mounting the mounting spring 71 may be directly formed on the pair of side wall portions 22b of the recess 22 of the main body unit 21. Specifically, a hooking portion 23 for hooking the hook portion 72 on one side wall portion 22b and an engaged portion 28 for engaging the first engaging portion 72c of the hook portion 72 are provided. The other side wall portion 22b is provided with a second engaged portion 29 to which the second engaging portion 73 is engaged. As a result, the mounting bracket 31 can be omitted, so that the number of parts can be reduced.

Further, the mounting spring 71 (in the present embodiment, at least one of the two mounting springs 71) may be integrally formed in the power supply case of the power supply device 61. As a result, the mounting spring 71 can be omitted, so that the number of parts can be reduced.

In the lighting fixture 11 according to the present embodiment described above, the mounting bracket 31 arranged in the recess 22 of the main body unit 21 and the light source unit 41 are arranged on the opposite side of the light source portion 51 and can be mounted on the mounting bracket 31. The mounting spring 71 of the light source unit 41 has a hook-shaped hook portion 72, the mounting bracket 31 has a hook portion 36 for hooking the hook portion 72, and the light source unit 41 is the main body unit 21. The hook portion 72 is configured to be hooked on the hook portion 36 when the hook portion 72 is moved in a direction away from the concave portion 22 of the hook portion 22. That is, since the fall prevention structure of the light source unit 41 including the hook portion 72 and the hook portion 36 is arranged in the recess 22 of the main body unit 21, the main body unit 21 can be miniaturized.

The shape of the luminaire 11 of the present embodiment is an example, and is not limited to the shape of the present embodiment. For example, when the shape of the luminaire 11 is a shape other than the elongated shape, the shape can be adapted accordingly. Further, the light source unit can be appropriately deformed according to the shape of the main body unit.
