[0014] A lighting fixture 100 as an example of a lighting fixture according to an embodiment of the present invention will be described with reference to Figs. 1 to 10. The lighting fixture 100 is a recessed lighting fixture that is recessed into, for example, a circular recessed hole H formed in a ceiling C that serves as an attachment surface as shown in Fig. 3. The lighting fixture according to the present invention is not limited to a recessed lighting fixture, but may be a direct-attached lighting fixture that is directly attached to a ceiling surface or the like, or a hanging lighting fixture that is hung from a ceiling surface or the like. In the following description, the up-down direction of the lighting fixture 100 will be described as the up-down direction when the lighting fixture 100 is installed on the ceiling C. A direction perpendicular to the up-down direction will be described as the radial direction. In the description of this embodiment, a state in which the lighting fixture 100 etc. is viewed from above is referred to as a planar view. A state in which the lighting fixture 100 etc. is viewed from a direction perpendicular to the up-down direction is referred to as a side view. A state in which the cross-sectional shape of the lighting fixture 100 etc. is viewed is referred to as a cross-sectional view.

[0015] As shown in Figures 1 to 3 and 6, the lighting device 100 mainly comprises a light source unit 10, a power supply unit 20 that supplies power to a light source 11 (in this embodiment, a COB type LED 11) of the light source unit 10, an electric wire 24 that connects the light source 11 and the power supply unit 20, a cylindrical first body 30 in which the light source unit 10 is arranged, and a cylindrical second body 40 in which the power supply unit 20 is arranged.

[0016] As shown in Figs. 6 and 7, the light source 11 is a part that emits light toward the irradiation surface side of the lighting fixture 100. As shown in Figs. 6 and 7, the light source 11 of this embodiment has a COB type LED 11 arranged on the upper part of the module reflector 14. The module reflector 14 is made of a resin material and is formed in a cylindrical shape. The module reflector 14 also has, on its upper surface, protrusions 16 (two in this embodiment) for mounting to the mounting plate part 32 of the first body 30, and a board guide part 15 for mounting the rectangular plate-shaped COB type LED 11. The two protrusions 16 protrude upward from the upper surface of the module reflector 14. One of the two protrusions 16 is inserted into the through hole 36 of the mounting plate part 32, and the other is arranged in the electric wire insertion part 33 and fitted into the mounting plate part 32, so that the module reflector 14 can be attached inside the first cylinder 30.

[0017] The board guide portion 15 surrounds the outer peripheral edge portion of the COB LED 11 so as to follow at least a part of the outer shape of the COB LED 11, and regulates the position of the COB LED 11 in the lateral direction. A lens 17 is provided below the module reflector 14. The module reflector 14 is placed inside the first body 30 with the COB LED 11 and the insulating sheet 81 placed inside the board guide portion 15.

[0018] The COB type LED 11 of this embodiment is a COB (Chip on board) type light emitting module in which an LED (Light emitting diode) element 12 is formed on a substrate 13. An electrode (not shown) electrically connected to an electric wire 24 for supplying power is provided on the surface of the substrate 13 on which the LED element 12 is formed. In this embodiment, the electrode of the COB type LED 11 is electrically connected to the electric wire 24 by using, for example, solder.

[0019] The power supply unit 20 is a power supply device for supplying power to the COB type LED 11 of the light source unit 10 to light up the LED element 12. The power supply unit 20 is configured such that a power supply circuit board 21, which is a printed wiring board processed into a rectangular shape and on which multiple electronic components are mounted, is housed in an insulating box-shaped power supply case 22.

[0020] The power supply unit 20 converts AC current supplied from an external commercial power supply into a predetermined DC current and supplies the converted current to the LED elements 12 of the COB type LED 11. The power supply unit 20 is electrically connected to a terminal block 70 via an electric wire 23. The terminal block 70 is disposed on a terminal block mounting plate 71 fixed to the upper surface of the second body 40 and protruding laterally.

[0021] When the lighting fixture 100 is attached to the ceiling C, the power supply unit 20 is electrically connected to the external commercial power supply by connecting the terminal block 70 to an external commercial power supply electric wire (not shown) on the underside of the ceiling. The power supply unit 20 and the COB type LED 11 are electrically connected to each other by an electric wire 24.

[0022] The first body 30 is a cylindrical body constituting the lower part of the lighting device 100, and in this embodiment, as shown in FIG. 9, is configured to have a shape in which a part of the cylindrical side is cut out. The first body 30 is formed by die-cast molding or the like using a metal such as aluminum. The first body 30 has a rectangular power supply guide part 31 in the center thereof, which accommodates the lower part of the power supply case 22 of the power supply unit 20. The outer peripheral surface of the power supply case 22 is formed to be slightly smaller in size than the inner peripheral surface of the power supply guide part 31. The power supply unit 20 can be stored in the first body 30 by inserting its lower part into the power supply guide part 31. The first body 30 also has a recess 34 on the side surface of the first body 30. The recess 34 is formed on the side surface of the first body 30 so as to extend in the vertical direction from the upper end to the lower end. In this embodiment, the recess 34 is configured as a cutout part formed to extend from the upper end to the lower end. The recess 34 also has the effect of increasing the visibility of the inside of the first body 30. The recess 34 in this embodiment is formed so that the power supply unit 20, the COB type LED 11, and the electric wires 24 can be visually observed.

[0023] In addition, a mounting plate portion 32 for mounting the upper surface of the module reflector 14 is provided inside the first body 30. The mounting plate portion 32 is provided on the lower end side of the power supply guide portion 31. The mounting plate portion 32 is a plate-shaped portion that separates the lower end of the power supply case 22 from the module reflector 14 and the COB type LED 11 stored in the board guide portion 15 of the module reflector 14. In this embodiment, an insulating sheet 26 is disposed between the COB type LED 11 and the mounting plate portion 32. The insulating sheet 81 is not an essential component and can be disposed as appropriate as necessary. Instead of the insulating sheet 81, a member that enhances heat dissipation, such as heat dissipation grease, can also be disposed.

[0024] The peripheral end of the mounting plate 32 is provided with an electric wire insertion portion 33 for allowing the electric wire 24 to be inserted in the vertical direction. The power supply insertion portion 33 provided on the mounting plate 32 is a space for passing the electric wire 24 to the light source 10 (COB type LED 11) side, and in this embodiment, as shown in FIG. 9, is formed by cutting out the mounting plate 32 and communicates with the recess 34. With this configuration, it becomes possible to check the position of the electric wire 24 from the outside when the second body 40 and the first body 30 are removed. In addition, since the electric wire 24 can be easily arranged in an appropriate position, the ease of assembly is improved.

[0025] The second body 40 is a tubular body that constitutes the upper part of the lighting device 100, and is configured to be cylindrical in this embodiment. The second body 40 has a flat portion 42 formed by cutting out two places on its side from the upper end to the lower end as shown in FIG. 2, and is formed in a hat shape when viewed from the side. The second body 40 is formed by die casting or the like using a metal such as aluminum. The second body 40 has a rectangular power guide portion 41 in the center that accommodates the upper part of the power case 22 of the power supply unit 20. The outer peripheral surface of the power case 22 is formed to be slightly smaller in size than the inner peripheral surface of the power guide portion 41. The power supply unit 20 can be stored in the second body 40 by inserting the upper part of the power supply unit 20 into the power guide portion 41. The power supply unit 20 in this embodiment is inserted into the power guide portion 31 of the first body 30 and the power guide portion 41 of the second body 40, and is stored inside the first body 30 and the second body 40.

[0026] In addition, a mounting flange 43 is provided at the lower end of the second body 40 for inserting a body mounting screw 85. The mounting flange 43 is provided at the lower end of the flat portion 42 so as to extend outward, and is formed so as to contact the upper surface of the first body 30. In this embodiment, the outer shape of the upper end of the first body 30 and the outer shape of the lower end of the second body 40 are formed to be substantially the same. The upper surface of the first body 30 and the lower surface of the second body 40 are arranged so as to overlap and fixed, so that their side surfaces are continuous. A body mounting screw insertion hole 35 is provided at the upper surface of the first body 30. The mounting flange 43 of this embodiment has a notch 44 in which a body mounting screw 85 can be arranged. The notch 44 of the mounting flange 43 is provided at a position corresponding to the body mounting screw insertion hole 35 of the first body 30. The body mounting screw 85 passes through the notch 44 of the second body 40 and the body mounting screw insertion hole 35 of the first body 30 to fix the first body 30 and the second body 40 together.

[0027] Further, an attachment spring 60 is disposed on the outer side of the flat portion 42 of the second body 40. The attachment spring 60 is a fixing means for mounting the lighting fixture 100 by embedding it in the embedding hole H of the ceiling C. The attachment spring 60 in this embodiment is a leaf spring formed by bending and curving a midsection of a plate-shaped metal member made of stainless steel or the like in multiple places, into a shape having an attachment portion 61, abutment portions 63, and end portions 64.

[0028] Here, a method of mounting the lighting fixture 100 on the ceiling C will be described with reference to FIG. First, an external commercial power supply wire (not shown) is connected to the terminal block 70, and then the ends 64 of the two mounting springs 60 are held by hand in the direction of the arrow A1 so as to approach the second body 40. Next, the lighting fixture 100 is tilted and inserted from the terminal block 70 side into the ceiling through the recessed hole H in the ceiling C in the direction of arrow A2, and the lighting fixture 100 is changed so that the second body 40 is oriented in the vertical direction. The upper end of the second body 40 and the end 64 of the mounting spring 60 are inserted into the recessed hole H. At this time, since the second body 40 is formed in a cut-out shape to provide the flat portion 42, the end 64 of the mounting spring 60 can be displaced to a position more radially inward. This makes it easier to insert the end 64 of the mounting spring 60 into the recessed hole H, improving the ease of installation of the lighting fixture 100.

[0029] Next, the lighting fixture 100 is pulled up in the direction of arrow A3. The lighting fixture 100 is pulled up until the flange surface 52 of the frame body 50, which will be described later, abuts against the ceiling C via the frame body gasket 83, and is attached to the ceiling C. At this time, the mounting spring 60 moves toward the ceiling back side while bending so that the abutment portion 63 slides within the embedding hole H. The restoring force of the mounting spring 60 causes the abutment portion 63 to abut against the inner circumferential surface of the embedding hole H and the periphery of the upper part of the embedding hole H, and the lighting fixture 100 is fixed to the ceiling C while being pulled up toward the ceiling back side.

[0030] The shape, mounting position, number, etc. of the mounting spring 60 are not limited to those of this embodiment. As shown in FIG. 4, the mounting spring 60 has a mounting portion 61 at its base. The mounting portion 61 has a through hole 62, and the mounting spring 60 is fixed to the upper surface of the second body 40 by screwing a screw 86 into the through hole 62 and the screw mounting hole 47 of the second body 40. In the lighting fixture 100 of this embodiment, the terminal block mounting plate 71 is also attached to the upper surface of the second body 40 at the same time by the screw 86. Specifically, the terminal block mounting plate 71 is disposed between the second body 40 and the mounting portion 61 of the mounting spring 60. The mounting spring 60 and the terminal block mounting plate 71 are attached to the upper surface of the second body 40 by screwing a screw 86 into the through hole 62 of the mounting spring 60, the through hole 72 provided in the terminal block mounting plate 71, and the screw mounting hole 47 of the second body 40.

[0031] 7 and 8, the second body 40 has a protrusion 48 extending from the lower end on a side surface of the second body 40, and the protrusion 48 is configured to be positionable so as to protrude toward the first body 30 and cover the recess 34. In this embodiment, the protrusion 48 is integrally formed so as to protrude continuously from a portion of the lower end of the second body 40. By fitting the protrusion 48 into the recess 38 formed as a cutout portion of the first body 30, the first body 30 and the second body 40 can be easily aligned.

[0032] As shown in FIGS. 7 and 8, the protrusions 48 are disposed on the outside of the electric wires 24 in a state where they are fitted into the recesses 34. As shown in FIG. With this configuration, the position of the electric wire 24 can be confirmed from the outside when the second body 40 and the first body 30 are detached. Also, when the second body 40 and the first body 30 are fitted together, the electric wire 24 can be stored.

[0033] Moreover, the second body 40 preferably has an inclined surface 45 on the end opposite to the side connected to the first body 30. The inclined surface 45 is provided on the upper surface of the second body 40, and is provided so as to chamfer a part of the upper surface. With this configuration, when the second body 40 is inserted into, for example, a circular embedding hole H formed in the ceiling C, contact between the upper surface of the second body 40 and the inner peripheral surface of the embedding hole H can be prevented, thereby improving the ease of installation of the lighting fixture 100.

[0034] As shown in Figs. 4, 6 and 7, the electric wire 23 connected to the power supply circuit board 21 is drawn to the upper surface side of the terminal block mounting plate 71 through the electric wire insertion hole 46 provided on the upper surface of the second body 40 and the notch 73 provided in the terminal block mounting plate 71. The electric wire 23 is drawn from the upper surface of the terminal block mounting plate 71 to the lower surface side of the terminal block mounting plate through the through hole 75 and connected to the terminal block 70. The electric wire 23 drawn to the lower surface side of the terminal block 70 and the terminal block mounting plate 71 is covered by the terminal block cover 74. The electric wire 23 is not exposed on the lower surface side of the terminal block mounting plate 71. Therefore, when the terminal block 70 and the second body 40 are inserted into the embedding hole H of the ceiling C, the electric wire 23 is prevented from coming into contact with the inner circumferential surface or upper end of the embedding hole H. This makes it difficult for the electric wire 23 to be subjected to a load due to contact and improves the workability of the lighting fixture 100.

[0035] On the other hand, the lens 17 provided below the module reflector 14 is a member formed in a shade shape with a diameter that increases downward. In the present embodiment, the lens 17 is described as being formed in an inclined shape, but is not limited to this. For example, the shape of the lens 17 may be a Fresnel lens or the like. Also, instead of the lens 17, a light control method such as a reflector may be adopted.

[0036] A plurality of positioning claws 18 (three in this embodiment) are formed on the periphery of lens 17 so as to protrude to the side. Diffusion sheet 19 is attached to the underside of lens 17 via lens packing 82. Diffusion sheet 19, lens 17, and lens packing 82 are supported by frame 50 attached to the underside of first body 30. Positioning grooves 51 are provided on the upper surface of frame 50, and positioning of lens 17 within frame 50 is performed by inserting positioning claws 18 provided on lens 17 into the grooves. Light from light source unit 10 is irradiated to the outside of lighting fixture 100 via frame 50.

[0037] The frame body 50 is a cylindrical body disposed at the bottom of the lighting fixture 100. The frame body 50 has a flange surface 52 extending outward from its bottom end. The frame body 50 is formed by die-casting or the like using a metal such as aluminum. The frame body 50 has a plurality of (three in this embodiment) positioning grooves 51 on its side surface corresponding to the positioning claws 18 of the lens 17. The frame body 50 has a plurality of (three in this embodiment) through holes 53 on its side surface. The frame body 50 is attached to the bottom of the first body 30 using a plurality of (three in this embodiment) frame body fixing screws 54. Specifically, the frame body 50 is disposed on the bottom end side of the first body 30 so that the through holes 53 overlap with the groove portion 37 provided on the bottom of the first body 30. The frame body 50 can be attached to the first body 30 by screwing the frame body fixing screws 54 into the through holes 53 of the frame body 50 so as to enter the groove portion 37 of the first body 30.

[0038] In this embodiment, a set screw (set screw) having the same diameter at the head and thread portion is used as the frame fixing screw 54, but this is not limited thereto, and a screw member having different diameters at the head and thread portion may be used. Also, the method of connecting the frame 50 and the first body 30 is not limited to the above-described method, and the frame 50 and the first body 30 may be connected by adhesive, or by providing a male thread portion and a female thread portion on the frame 50 and the first body 30, respectively. 6 and 8, a frame packing 83 is disposed between the frame body 50 and the ceiling C. The frame packing 83 is disposed on the upper surface of the flange surface 52 of the frame body 50, and a portion of the frame packing 83 covers the side surface of the frame body 50. This makes it possible to ensure airtightness between the ceiling C and the flange surface 52 of the frame body 50.

[0039] An example of a process for assembling lighting device 100 will be described below with reference to Fig. 6. Note that the order of the steps in the assembly process described below may be reversed. First, the COB LED 11 and the insulating sheet 81 are placed inside the board guide portion 15 of the module reflector 14 . Next, the diffusion sheet 19, the lens packing 82, and the lens 17 are placed in the frame 50. At this time, the positioning claws 18 of the lens 17 are inserted into the positioning grooves 51 of the frame 50, so that the lens 17 can be easily positioned in the appropriate position within the frame 50. Next, the frame 50 is placed below the first body 30 and attached using the frame fixing screws 54. At this time, the lens 17 is inserted from the lower side of the module reflector 14, and positioned at an appropriate position within the first body 30.

[0040] Next, the lower part of the power supply case 22 is stored in the power supply guide part 31 of the first body 30. At this time, as shown in Figs. 7 and 8, the electric wire 24 connecting the COB type LED 11 and the power supply circuit board 21 is passed through the electric wire insertion part 33 from the side of the first body 30 where the COB type LED 11 is arranged, and is drawn to the power supply guide part 31 side. Since the electric wire insertion part 33 of the first body 30 communicates with the recess 34, the worker can perform the assembly work while visually checking the positions of the COB type LED 11, the module reflector 14, the electric wire 24, and the power supply case 22 from the recess. This improves the assembly workability. In addition, since the power supply part 20 is stored in the first body 30 and the second body 40, the length of the electric wire 24 can be made shorter than when the power supply part 20 is stored in one bottomed cylindrical part as in the lighting fixture disclosed in Patent Document 1. Furthermore, by forming the electric wire insertion portion 33 through which the electric wire 24 is inserted in a notch shape as in this embodiment, the electric wire 24 can be easily routed as compared with the case where the electric wire insertion portion 33 is formed in a through hole shape.

[0041] Next, the second body 40 is placed on the upper surface side of the first body 30 so that the upper part of the power supply case 22 is stored in the power supply guide part 41. At this time, the convex part 48 of the second body 40 is placed so as to cover the concave part 34 of the first body 30. This makes it easy to place the second body 40 in an appropriate position, and the electric wires 24 can be stored by the first body 30 and the convex part 48. Next, the first fuselage 30 and the second fuselage 40 are connected and fixed using the fuselage mounting screw 85. The fuselage mounting screw 85 fixes the first fuselage 30 and the second fuselage 40 through the notch 44 of the second fuselage 40 and the fuselage mounting screw insertion hole 35 of the first fuselage 30.

[0042] The mounting springs 60 and the terminal block mounting plate 71 are fixed to the top surface of the second body 40 using screws 86. The terminal block mounting plate 71 and the mounting portions 61 of the two mounting springs 60 are arranged in predetermined positions on the top surface of the second body 40. The mounting springs 60 and the terminal block mounting plate 71 are attached to the top surface of the second body 40 by screwing the screws 86 into the through holes 62 of the mounting springs 60, the through holes 72 of the terminal block mounting plate 71, and the screw mounting holes 47 of the second body 40.

[0043] At this time, the electric wires 23 connecting the power supply circuit board 21 and the terminal block 70 are drawn from inside the second body 40 to the upper surface side of the terminal block mounting plate 71. Specifically, the electric wires 23 are drawn through the electric wire insertion holes 46 provided on the upper surface of the second body 40 and the notches 73 provided in the terminal block mounting plate 71. The electric wires 23 are drawn from the upper surface of the terminal block mounting plate 71 to the lower surface side of the terminal block mounting plate 71 through the through holes 75 and connected to the terminal block 70. The electric wires 23 drawn to the lower surfaces of the terminal block 70 and the terminal block mounting plate 71 are covered with a terminal block cover 74.

[0044] Moreover, the mounting spring 60 is positioned so as to face the flat surface portion 42 of the second body 40. The second body 40 is formed in a cut-out shape so as to have the flat surface portion 42. This makes it easier to insert the upper part of the second body 40 into the embedding hole H in the ceiling C. Also, since the end portion 64 of the mounting spring 60 can be positioned close to the central axis of the second body 40, it becomes easier to insert the end portion 64 into the embedding hole H. These improve the ease of installation of the lighting fixture 100.

[0045] The terminal block mounting plate 71 is disposed so as to extend toward the side of the second body 40 to which the mounting springs 60 are not attached. In the case of the present embodiment, the two mounting springs 60 are disposed so as to extend in a direction inclined at approximately 90 degrees with respect to the direction in which the terminal block mounting plate 71 extends. This prevents the terminal block mounting plate 71 from coming into contact with the mounting springs 60 when mounting the lighting fixture 100, improving ease of installation.

[0046] 10, a display sticker 84 is provided at the boundary between the first body 30 and the frame 50. The display sticker 84 is a seal member for indicating installation and the like, and is attached to the side surface of the boundary between the first body 30 and the frame 50. The display sticker 84 is attached so as to cover the positioning groove 51 of the frame 50 and the positioning claw 18 of the lens 17. By attaching the display sticker 84 to the boundary in this manner, it is possible to prevent light leakage and the intrusion of foreign objects such as insects into the lighting fixture 100.

[0047] In this embodiment, the display sticker 84 is provided at the boundary between the first body 30 and the frame 50, but it may also be provided, for example, at the boundary between the first body 30 and the second body 40.

[0048] As described above, the lighting fixture 100 of the present invention is a lighting fixture 100 that is mounted by being embedded in a recessed hole H provided in a mounting portion such as a ceiling C, and comprises a light source 11, a power supply unit 20 that supplies power to the light source 11, an electric wire 24 that connects the light source 11 and the power supply unit 20, a cylindrical first body 30 in which the light source 11 is arranged, and a cylindrical second body 40 in which the power supply unit 20 is arranged, the second body 40 being connected to the end of the first body 30 opposite the side of the illumination surface of the light source 11, the first body 30 having an electric wire insertion portion 33, and the electric wire 24 extending from the power supply unit 20 to the light source 11 side via the electric wire insertion portion 33. By configuring the power supply unit 20 to be housed in the first body 30 and the second body 40 in this manner, the length of the electric wire 24 can be made shorter than when the power supply unit 20 is housed in a single cylindrical portion with a bottom. Also, by forming the electric wire insertion portion 33 through which the electric wire 24 passes in a notched shape, the electric wire 24 can be easily routed compared to when the electric wire insertion portion 33 is formed in a through-hole shape, improving the ease of assembly.

[0049] In addition, the first body 30 may have a recess 34 on a side surface of the first body 30, and the second body 40 may have a protrusion 48 on a side surface of the second body 40, the protrusion 48 protruding toward the first body 30 side and configured to be able to fit into the recess 34. With this configuration, the second body 40 can be easily disposed at an appropriate position relative to the first body 30. In addition, since the work can be performed while visually checking the inside of the first body 30 through the recess 34, the assembly workability is improved.

[0050] Further, the recess 34 communicates with the electric wire insertion portion 33, and the protrusion 48 is disposed outside the electric wire 24 in a state of being engaged with the recess 34. With this configuration, it becomes possible to check the position of the electric wire 24 from the outside when the second body 40 and the first body 30 are detached. In addition, when the second body 40 and the first body 30 are connected, the electric wire 24 can be stored inside the second body 40 and the first body 30.

[0051] In addition, the second body 40 may have an inclined surface 45 at the end opposite to the end connected to the first body 30 . By configuring it in this manner, when inserting the lighting fixture 100 into, for example, a circular recessed hole H formed in the ceiling C, contact between the upper surface of the second body 40 and the inner surface of the recessed hole H can be prevented, thereby improving the ease of installation of the lighting fixture 100.

[0052] In addition, a frame body 50 may be provided at the end of the first body 30 opposite the side where it is connected to the second body 40, and a display sticker 84 may be provided at the boundary between the first body 30 and the frame body 50. With this configuration, by attaching the display sticker 84 to the boundary portion, it is possible to prevent light leakage and the intrusion of foreign objects such as insects into the lighting fixture 100.
