  The lighting fixture 11 which concerns on embodiment of this invention is demonstrated using FIGS. 1-5. The luminaire 11 according to this embodiment is a luminaire using a plurality of LED elements 42 as light sources. As shown in FIG. 1, the lighting fixture 11 is a ceiling light that is directly attached to a fixture mounting surface (not shown) such as a ceiling. In the following description, the side of the luminaire 11 that emits light is the irradiation surface side of the luminaire 11, and the side of the luminaire 11 that faces the fixture mounting surface such as the ceiling is the mounting surface side of the luminaire 11 (in the mounted state). This will be described as the ceiling side. Moreover, the up-down direction of the lighting fixture 11 is demonstrated as an up-down direction (up-down direction in FIG. 1, FIG. 3) in the state in which the lighting fixture 11 was installed in fixture mounting surfaces, such as a ceiling. A direction perpendicular to the vertical direction will be described as a radial direction. Moreover, in description of this embodiment, let the state which looked at the lighting fixture 11 grade | etc., From the downward direction be planar view. A state in which the luminaire 11 and the like are viewed from a direction orthogonal to the vertical direction is referred to as a side view. A state in which the cross-sectional shape of the lighting fixture 11 or the like is viewed is taken as a cross-sectional view.

  The lighting fixture 11 mainly includes a fixture main body 21, a power supply unit 31, a light source unit 41, a shade 51, a power supply cover 61, a connection unit 71, a light receiving unit 81, and a protection member 91. The lighting fixture 11 has a circular shape in plan view.

The fixture main body 21 constitutes the main body of the lighting fixture 11. The instrument body 21 is a so-called base or chassis member. The instrument main body 21 has a circular outer contour shape in plan view. The instrument body 21 holds the light source unit 41, the shade 51, the power supply cover 61, the protection member 91, and the like. The instrument main body 21 includes a light source attachment portion 22, a concave portion 25, a ridge portion 26, and a housing portion 23, and is integrally formed as a single member.
In addition, in this embodiment, although the light source attachment part 22, the recessed part 25, the protruding item | line part 26, and the accommodating part 23 are integrally formed as the instrument main body 21, it does not specifically limit.

  The light source attachment part 22 is substantially annular in plan view, and is composed of a plurality of (four in this embodiment) light source attachment surface parts 22a which are flat surfaces. The recess 25 is disposed between the plurality of light source mounting surface portions 22a. The accommodating part 23 is provided in the radial direction center part of the instrument main body 21. The light source mounting portion 22 is provided on the radially outer side of the housing portion 23. The protruding portion 26 is provided on the radially outer side of the light source mounting portion 22. A plurality of holding portions 29 for holding the shade 51 are provided on the peripheral portion of the instrument main body 21. The plurality of holding portions 29 are arranged at substantially equal intervals on the peripheral portion of the instrument main body 21. The appliance main body 21 considers durability that can hold the power source cover 61, the light source unit 41, the shade 51, and the like in which the power source unit 31 is accommodated, and thermal conductivity for dissipating heat generated by the light source unit 41, It is formed using a metal plate such as iron, aluminum, or an alloy thereof. The instrument main body 21 can be formed of other materials such as other alloy materials and resins as well as the above-described metal materials as long as the material has high durability and heat dissipation.

  The light source attachment part 22 is a part to which the light source part 41 is attached. The light source attachment portion 22 is provided with a constant width along the circumferential direction of the instrument main body 21, and a plurality of light source attachment portions 22 are arranged in a substantially arc shape around the outer peripheral side of the accommodating portion 23 in the central portion in the radial direction of the instrument main body 21. The light source mounting part 22 has a light source mounting surface part 22a and a light source fixing part 22b. The light source mounting surface portion 22a is an arc-shaped flat surface having a predetermined width in the circumferential direction and the radial direction, and is a surface for mounting the LED light source module 44 in contact therewith. As shown in FIG. 3, the light source mounting surface portion 22 a is a protruding surface that protrudes toward the irradiation surface. The light source fixing portion 22b is a screw hole for screwing a screw member provided in the vicinity of the four corners in the vicinity of the outer periphery of the light source mounting surface portion 22a in order to fix the light source portion 41 with a screw member. The light source fixing portion 22b is preferably formed by burring, for example, because the length of the screwed portion with the screw member can be ensured long. A housing portion 23 is formed at the center of the instrument body 21 in the radial direction so as to protrude toward the irradiation surface, and the light source mounting portion 22 is provided in a radially outer region so as to surround the housing portion 23. The light source mounting portion 22 is formed in a region radially inward from the outer peripheral edge of the instrument main body 21. Since the light source mounting part 22 also functions as a heat radiating part that transmits heat generated by the light source part 41 and releases it to the outside, the light source mounting surface part 22a to which the light source part 41 is attached has a wide contact area with the light source part 41. It is formed so as to be flat.

The concave portions 25 are portions that extend radially from the outer peripheral side of the housing portion 23 in the instrument main body 21. The recess 25 is disposed between the plurality of light source attachment portions 22. That is, the recessed portions 25 and the light source mounting portions 22 are alternately arranged around the outer peripheral side of the housing portion 23 in the instrument main body 21. The recess 25 is formed so as to protrude to the mounting surface side. The length in the radial direction of the recess 25 is substantially the same as the width in the radial direction of the light source mounting portion 22 adjacent to the recess 25. The recess 25 has a taper along the radial direction, and has a cross-sectional shape that is substantially trapezoidal. Therefore, the recess 25 functions as a reinforcing rib for reinforcing the instrument main body 21. Moreover, the rigidity of the instrument main body 21 can be improved by extending the recessed part 25 radially (from four in this embodiment) radially from the outer peripheral side of the accommodating part 23 in the instrument main body 21. That is, the instrument body 21 is formed with a portion bent by the recess 25. The bent shape has higher bending rigidity than the flat shape. Therefore, the rigidity of the instrument body 21 can be increased by forming a plurality of bent portions in the radial direction of the instrument body 21 and in the circumferential direction.
In the present embodiment, the recess 25 protrudes toward the mounting surface, but is not particularly limited. The concave portion 25 may be a bent shape having a function as a reinforcing rib for improving the rigidity of the instrument body 21. For example, the concave portion 25 may be formed so as to protrude toward the irradiation surface. The cross-sectional shape of the recess 25 may be formed in a substantially rectangular convex shape, a cross-sectional arc shape, a cross-sectional uneven shape, or the like. The length of the recess 25 in the radial direction is not limited to the same dimension as the width in the radial direction of the light source mounting portion 22, and the rigidity of the instrument body 21 is further increased by making it longer than the radial width of the light source mounting portion 22. Since it can raise, it is preferable. Moreover, even if the recess 25 has a radial length smaller than the radial width of the light source mounting portion 22, the same effect as that of the present embodiment can be obtained by providing a plurality of recesses 25 in the radial direction. In addition, the instrument body 21 has a larger surface area by providing the recesses 25, and can improve heat dissipation as compared to an instrument body in which the recesses 25 are not provided.

  The protruding portion 26 is a portion that is adjacent to the outside in the radial direction of the light source mounting portion 22 and protrudes to the irradiation surface side. The protruding portion 26 is intermittently disposed along the outer peripheral side of the light source unit 41. The ridge portion 26 is formed in a plurality of arc shapes formed in an intermittent state along the circumferential direction. That is, in the instrument main body 21, there is a region where the protruding portion 26 is not formed between the light source unit 41 and the holding unit 29. One end of the protection member 91 is attached to the lower end of the protrusion 26 by a screw member. The protruding portion 26 has a function as a reinforcing rib for reinforcing the instrument main body 21, and the cross-sectional shape is formed in a substantially trapezoidal convex shape. Thereby, the rigidity of the circumferential direction in the instrument main body 21 can be improved.

  The accommodating portion 23 is a portion where one end side of the connecting portion 71 is accommodated. The connection part 71 connects the lighting fixture 11 with the wiring fixture arrange | positioned on fixture mounting surfaces, such as a ceiling. The accommodating part 23 is provided in the radial direction center part of the instrument main body 21. The accommodating portion 23 has a circular outer shape in a plan view and is concave downward in a cross-sectional view, and is formed so as to protrude to the irradiation surface side. The accommodating part 23 has the substantially cylindrical surrounding wall part 23a and the annular | circular shaped bottom part 23b provided in a row by this surrounding wall part 23a. A circular opening 23 c is formed at the center in the radial direction of the bottom 23 b of the housing 23. The opening 23c is a portion for exposing the connecting portion 71. A light receiving hole 23 d for exposing one end of the light receiving unit 81 is formed at a position corresponding to the light receiving unit 81 on the bottom 23 b of the housing unit 23. Through holes 23e and 23e for inserting wiring (not shown) for electrically connecting the LED light source module 44 and the power supply unit 31 are formed in the vicinity of the light receiving hole 23d in the peripheral wall portion 23a of the housing portion 23. ing. The through holes 23e and 23e are provided between the light receiving unit 81 and the LED light source module 44. The structure in which the housing portion 23 is substantially bottomed cylindrical projecting to the irradiation surface side and the through holes 23e and 23e are provided in the peripheral wall portion 23a is bent to a wiring that electrically connects the LED light source module 44 and the power source portion 31. It is hard to give stress by. That is, the wiring connected to the LED light source module 44 is inserted into the through holes 23e and 23e and drawn into the accommodating portion 23 on the mounting surface side of the instrument body 21. At this time, when the through holes 23e and 23e are provided so as to open in the vertical direction of the instrument body 21, the direction in which the through holes 23e and 23e are opened does not coincide with the direction in which the wiring extends. Therefore, if it is going to draw in wiring from the irradiation surface side of the instrument main body 21 to the attachment surface side, it is necessary to forcibly pull the wiring in the vicinity of the through holes 23e and 23e by bending it up and down. On the other hand, in the present embodiment, the through holes 23e and 23e are provided in the peripheral wall portion 23a of the housing portion 23 so as to open toward the side surface direction of the instrument body 21, and therefore the direction in which the through holes 23e and 23e are opened and the wiring The direction in which the line extends coincides. Therefore, the wiring can be drawn from the irradiation surface side of the instrument main body 21 to the mounting surface side without forcibly bending it in the vicinity of the through holes 23e and 23e, and stress due to bending is hardly applied. The accommodating part 23 is adjacent to the light source attaching part 22 to which the light source part 41 is attached. When the dimension (height dimension) in the vertical direction of the accommodating part 23 increases, the accommodating part 23 blocks the light from the light source part 41 to the shade 51. The shadow of the accommodating part 23 will be reflected. For this reason, in this embodiment, by accommodating only part of the power supply unit 31 or the connection unit 71 in the housing unit 23, the volume of the housing unit 23 is suppressed, the housing unit 23 is formed in a flat shape, and the light source unit 41. Makes it difficult to block the light from.

  The power supply unit 31 is a power supply circuit for supplying power to the LED element 42 included in the light source unit 41 to light the LED element 42. The power supply unit 31 is a power supply circuit in which a plurality of electronic components are mounted on a power supply substrate 33 which is a printed wiring board processed into a substantially arc shape having a predetermined width. The power supply unit 31 converts an alternating current supplied from an external commercial power source into a predetermined direct current, and supplies the converted current to a plurality of LED elements 42 mounted on the substrate 43. The power supply unit 31 is accommodated in the power supply cover 61 and attached to the top plate part 64 of the power supply cover 61 via a plurality of (six in this embodiment) spacers 40. Thus, a space is formed between the power supply cover 61 and the power supply unit 31 to ensure an electrical insulation distance. The power supply unit 31 is provided with a connector 32. When attaching the lighting fixture 11 to a fixture mounting surface such as a ceiling, the power source 31 is connected to an external commercial power supply via the ceiling wiring fixture for the lighting fixture by connecting the connector 32 to a connector (not shown) on the wiring fixture side. And electrically connected. The power supply unit 31 and the light source unit 41 are electrically connected by wiring (not shown).

  The light source unit 41 is a part that emits light toward the irradiation surface side of the lighting fixture 11. The light source unit 41 is disposed on the outer peripheral side of the power supply unit 31. The light source unit 41 includes a plurality of LED elements 42 and has a flat plate shape that is disposed on the light source mounting surface portion 22 a that is a flat surface of the light source mounting portion 22. Specifically, the light source unit 41 includes a plurality (four in this embodiment) of LED light source modules 44, and each LED light source module 44 has a plurality of substrates 43 on a flat module substrate. The LED element 42 which is a point light source is mounted and configured. The plurality of LED elements 42 are arranged at substantially equal intervals in a substantially concentric manner with the opening 23 c of the instrument body 21 as the center. As shown in FIG. 2, the light source unit 41 and the power supply unit 31 are arranged at positions that do not overlap each other in plan view.

The board | substrate 43 which the LED light source module 44 has is formed in the substantially circular arc shape which has predetermined width in planar view, as shown in FIG. The substrate 43 has end portions 43a that are substantially parallel to each other at opposite ends in the circumferential direction (see FIG. 5). The end portion 43a is an example of a substantially parallel end portion of the present invention. Since all the substrates 43 of the LED light source module 44 have the same shape and the same area, they can be easily manufactured, which is preferable. Further, the shape of the inner peripheral end of the substrate 43 is the same as or similar to the shape of the outer peripheral end of the substrate 43. As a result, when a plurality of substrates 43 are produced by cutting from one plate-shaped substrate material, the substrates 43 can be arranged side by side on the substrate material, and there are few parts to be discarded and the manufacturing yield is improved. Therefore, it is preferable. The substrate 43 further has non-parallel end portions 43b formed along the radial direction at both ends corresponding to the circumferential direction. The LED light source modules 44 are connected by wiring components 45 that electrically connect the LED light source modules 44 with the non-parallel end portions 43b in the circumferential direction facing each other. The LED light source module 44 can form the light source portion 41 having a substantially annular shape by connecting the non-parallel end portions 43b to face each other. The wiring component 45 is disposed at a position corresponding to the recess 25 (in this embodiment, a position below the recess 25). Each LED light source module 44 is disposed so as to surround the radially outer side of the accommodating portion 23. Each LED light source module 44 is attached to the light source attachment portion 22 with four screw members 49. The LED light source module 44 is electrically connected to the power supply unit 31 by an electric wire (not shown). Each LED light source module 44 is fixed with the back surface of the mounting surface of the substrate 43 in contact with the light source mounting surface portion 22a of each light source mounting portion 22, so that when each LED light source module 44 generates heat, the LED light source module 44 Heat is transmitted to the instrument body 21. When the ambient temperature is lower than the temperature of the instrument body 21, the heat transmitted to the instrument body 21 is transmitted to the air around the instrument body 21. Thereby, the heat transmitted to the instrument main body 21 is dissipated to the attachment surface side of the instrument main body 21 via each light source attachment surface part 22a.
In addition, each LED light source module 44 may be attached to the light source attachment part 22 via a heat conductive sheet (not shown) or heat dissipation grease, and thereby higher heat dissipation can be obtained.
In this embodiment, the surface mount type LED element is used as the light source. However, the type of the light source is not limited to the LED element, and can be realized by, for example, a COB light emitting module or an organic EL element (OLED). It is.

  In the light source unit 41, a plurality of LED elements 42 are disposed at least on the irradiation surface side of the light source mounting surface portion 22 a of the light source mounting portion 22. This is because the LED element 42 mounted on the substrate 43 serves as a heat generation source, and at least the LED element 42 is arranged in the region of the light source mounting surface portion 22a to improve heat dissipation efficiency. For example, the size / shape of the LED light source module 44 in a plan view and the size / shape of the light source mounting surface portion 22a in a plan view need not be the same. That is, if the LED element 42 that is a heat source is arranged in the region of the light source mounting surface portion 22a via the substrate 43, a heat dissipation effect can be obtained. Therefore, a portion where the LED 42 is not mounted on the substrate 43 such as an outer peripheral edge portion of the substrate 43 may be disposed so as to protrude from the region of the light source mounting surface portion 22a. For example, in the present embodiment, both end portions of each LED light source module 44 in the circumferential direction are arranged so as to protrude from the region of the light source mounting surface portion 22a and to be positioned below the recess 25.

  The shade 51 is a member that is attached so as to cover the irradiation surface side of the instrument main body 21 and distributes the light from the light source unit 41 to the outside while reflecting and diffusing the light. The seed 51 is formed of a resin material having translucency. The overall shape of the shade 51 is circular in plan, and gently swells in a dome shape on the lower surface side. The shade 51 has a structure that can be attached to and detached from the instrument main body 21 for cleaning the inside of the shade 51 or replacing parts of the instrument main body 21. A held portion (not shown) for attaching the shade 51 to a holding portion 29 of the instrument main body 21 is formed at the opening edge portion on the upper surface side of the shade 51. In addition, the shape of the shade 51 in this embodiment is an example, Comprising: In addition to a dome shape, it can also be made into a cylindrical shape, a square tube shape, etc.

  In the lighting fixture 11 according to the present embodiment described above, the power supply unit 31 is accommodated in the power supply cover 61, and the power supply cover 61 is attached to the attachment surface side of the fixture body 21. Thereby, it is possible to divide the assembling process of the lighting fixture, and to improve the assembly workability. Furthermore, in the lighting fixture 11 according to the present embodiment, the connection portion 71 connected to the wiring fixture is attached in the power supply cover 61, and the power supply cover 61 is attached to the attachment surface side of the fixture main body 21. Thereby, the assembly workability | operativity of a lighting fixture can be improved further. That is, as in the present embodiment, the power supply cover 61 that is a unit in which the power supply unit 31 and the connection unit 71 are assembled and the instrument main body 21 that is a unit in which the light source unit 41 and the like are assembled can be assembled separately. Therefore, it is possible to divide the assembling process of the lighting fixture and improve the assembling workability. Moreover, when attaching the connection part 71 to the instrument main body 21, the connection part 71 is often attached to the surface of the instrument main body 21 opposite to the LED light source module 44, and it is necessary to perform attachment work on both surfaces of the instrument main body 21. This makes the work complicated. In the case where the connection portion 71 is attached to the power supply cover 61 as in the present embodiment, the connection portion 71 is attached to the same surface as the power supply portion 31 in the power supply cover 61, and the connection portion 71 is not attached to the instrument main body 21. Therefore, the attachment work of the connection part 71, the LED light source module 44, and the power supply part 31 should just be performed only on one surface of the instrument main body 21 and the power supply cover 61, and can improve assembly workability | operativity.

  In the luminaire 11, the power supply unit 31 is attached to the power supply cover 61 via the spacer 40, and a space is provided between the power supply cover 61 and the power supply unit 31. Thereby, the electrical insulation distance (for example, creepage distance) between the power supply part 31 (power supply board | substrate 33) and the power supply cover 61 is securable. Further, since the power supply substrate 33 is directly attached to the power supply cover 61 by the spacer 40, no other attachment member is required, and the attachment can be easily performed.

  Moreover, in the lighting fixture 11, as shown in FIG. 2, the light source part 41 and the power supply part 31 are arrange | positioned in the position which does not mutually overlap in planar view. As a result, the heat generated by the light source unit 41 and the power source unit 31 does not propagate to each other, and each is not easily affected by the heat.

  Moreover, in the lighting fixture 11, it has the some protrusion 26 on the outer peripheral side of this light source part 41 so that the fixture main body 21 may surround the circumference | surroundings of the light source part 41, and also the holding | maintenance part which is a shade attachment metal fitting in the outer peripheral side 29. Between the light source part 41 and the holding | maintenance part 29, it has a part which does not have the protrusion part 26. FIG. By providing the protrusions 26 intermittently, it is easy to remove insects, dust and the like that have entered from the intermittent parts of the protrusions 26 even when the protective member 91 is attached. Further, since the other portions except for the vicinity of the holding portion 29 are surrounded by the ridge portion 26 around the light source portion 41, the structure is such that the user cannot easily touch the LED light source module 44. Such a structure can improve safety.

  Moreover, in the lighting fixture 11, the light source part 41 has the board | substrate 43 which is an arc-shaped module board | substrate, and the both ends of the circumferential direction of this board | substrate 43 have the substantially parallel linear edge part 43a. Thereby, when manufacturing a plurality of substrates 43 by cutting from one plate-shaped substrate material, it is possible to arrange the molds of the substrates 43 side by side on the substrate material, and efficiently from one substrate material. Since the substrate 43 can be cut off and the number of parts to be discarded is small and the manufacturing yield is improved, the manufacturing cost can be reduced.

  Further, in the lighting fixture 11, the housing portion 23 has a through hole 23 e through which a wiring for electrically connecting the light receiving portion 81 and the LED light source module 44 is inserted, and the through hole 23 e is formed between the light receiving portion 81 and the LED light source module 44. Between. Thus, by providing the through hole 23e for drawing out the wiring in the vicinity of the light receiving hole 23d of the housing portion 23, the position of the through hole 23e can be easily recognized in a plan view, and the assembling work can be easily performed.

  In the luminaire 11, the plurality of LED light source modules 44 includes the arc-shaped substrate 43, and the substrate 43 has a non-parallel end portion 43 b along the radial direction at the circumferential end portion. The non-parallel end portions 43 b of the plurality of LED light source modules 44 are opposed to each other, the adjacent substrates 43 are connected by the wiring components 45, and the wiring components 45 are arranged at positions corresponding to the recesses 25. Even if the non-parallel end portions 43b of the LED light source modules 44 are arranged close to each other, an appropriate insulation distance can be provided. Moreover, the structure formed in the shape which has the substantially parallel edge part 43a and the non-parallel edge part 43b along radial direction in the edge part of the circumferential direction of the board | substrate 43 of each LED light source module 44 is the circle | round | yen of the board | substrate 43. Compared with the case where the end portions in the circumferential direction are formed only by the end portions along the radial direction, the facing area of the adjacent end portions in the adjacent LED light source modules 44 is small. Therefore, even when the substrate 43 is thermally expanded due to heat generated by the LED elements 42, the shape of the substrate 43 as in this embodiment reduces the amount of contact between the substrates 43 and suppresses stress on the substrate 43. The stress on the wiring component 45 due to the thermal expansion of the substrate 43 can be reduced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said Example, A various change is possible. For example, although the luminaire 11 is a round shape, it may be a square shape or other shapes. Moreover, you may apply to a pendant light etc. besides a ceiling light. In the case of a pendant light, the connecting portion corresponds to, for example, a wiring cable. In the case of a pendant light that can be connected to a duct rail arranged on the ceiling surface, the connecting portion corresponds to, for example, a wiring duct plug and a wiring cable connected thereto. Therefore, the connection part in this invention shall be interpreted in a broad sense by the kind and form of a lighting fixture.

  The shape of the instrument main body 21 of this embodiment is an example, and is not limited to the shape of this embodiment. For example, when the shape of the luminaire 11 is a square shape other than the round shape or other shapes, the shape can be set accordingly. Further, the shape of the instrument main body 21 can be appropriately modified according to the shape of the light source unit 41.
