The inclined portion 59 is inclined with respect to the inner arm portion 53. The bent portion 60 is bent in a substantially V shape. The coupling portion 55 has a flat plate shape, and couples the inner arm portion 53 and the outer arm portion 54. In the present embodiment, the width of the coupling portion 55 is substantially the same as the width W <b> 1 of the inner arm portion 53.

  FIG. 6 is a perspective view showing the frame 3. The frame 3 is cylindrical. In the present embodiment, the frame 3 is made of metal, but may be made of ceramic, synthetic resin, wood, or the like. A flange 32 is formed at the lower part of the frame 3. The frame 3 has three openings 31 corresponding to the three attachment springs 5 (FIG. 1). The width W5 of the opening 31 is larger than the width W1 of the inner arm portion 53 and the coupling portion 55 and smaller than the width W2 of the outer arm portion 54. The number of openings 31 is changed according to the number of attachment springs 5. The opening 31 penetrates from the outer wall surface 34 of the frame body 3 to the inner wall surface 35 of the frame body 3. In the present embodiment, the opening 31 has a rectangular shape.

  Three first upper edge portions 33 (edge portions), two second upper edge portions 36, and a plurality of third upper edge portions 38 are formed in a circular shape on the upper portion of the frame 3. The three first upper edge portions 33 are formed at substantially equal intervals corresponding to the three attachment springs 5. The first upper edge portion 33 has a relatively shallow concave shape with respect to the third upper edge portion 38. The number of first upper edge portions 33 can be set to an arbitrary number depending on the number of attachment springs 5. The two second upper edges 36 are opposed to each other. The second upper edge 36 is concave with respect to the third upper edge 38. A concave portion 37 is formed in the second upper edge portion 36. The plurality of third upper edge portions 38 are in contact with the sandwiching portions 24 of the housing 25 (FIG. 4).

  FIG. 7 is a perspective view showing the frame 3 in which the mounting spring 5 is arranged. FIG. 8 is a cross-sectional view showing the frame 3 on which the mounting spring 5 is mounted. FIG. 9 is an enlarged cross-sectional view showing the vicinity of the first end 51 of the mounting spring 5 of FIG. 8 and 9, the frame body 3 to which the lamp body 1 is fixed is shown. In order to simplify the drawing, the oblique lines indicating the cross section of the mounting spring 5 and the reflecting member 7 (FIG. 4) are omitted. Yes.

  As shown in FIG. 7, the attachment spring 5 is inserted into the frame body 3 through the opening 31 from the outside of the frame body 3 and supported by the frame body 3.

  As shown in FIG. 8, the first end 51 of the attachment spring 5 is supported by the first upper edge 33 of the frame 3. The inner arm portion 53 is located inside the frame body 3 and extends downward from the first end portion 51 along the inner wall surface 35. The connecting portion 55 is inclined obliquely downward from the base end of the inner arm portion 53, passes through the opening 31, and connects the inner arm portion 53 and the outer arm portion 54. The coupling portion 55 is located in the opening 31. The outer arm portion 54 is located outside the frame body 3, extends obliquely downward from the lower end of the coupling portion 55, bends substantially in a V shape, and extends obliquely upward to the second end portion 52. The second end 52 is located outside the frame body 3.

  As shown in FIG. 9, the first end 51 of the mounting spring 5 is sandwiched between the lamp body 1 and the first upper edge 33 of the frame 3. As a result, the attachment spring 5 is prevented from coming off from the first upper edge portion 33 and is attached to the frame body 3.

  Specifically, prior to the first end 51 being sandwiched between the lamp body 1 and the first upper edge 33, the first flange portion 56 of the mounting spring 5 is engaged with the first upper edge 33 of the frame 3. Is done. As a result, the first protrusion 57 contacts the first upper edge 33 and protrudes from the inside of the frame body 3 toward the outside. In addition, the first hooking portion 58 is hooked on the first upper edge portion 33. As a result, the attachment spring 5 is temporarily fixed to the frame 3. Further, the width W3 between the inner surface of the first hook portion 58 and the inner surface of the inner arm portion 53 is larger than the wall thickness W4 of the frame 3. Accordingly, play is imparted to the first end portion 51 of the mounting spring 5. Further, the first protrusion 57 of the attachment spring 5 temporarily fixed is sandwiched between the sandwiching portion 24 and the first upper edge portion 33 of the housing 25. As a result, the attachment spring 5 is attached to the frame 3. In the present embodiment, since the first upper edge portion 33 is concave, a minute gap is formed between the first projecting portion 57 and the sandwiching portion 24. Note that the clip portion 24 may be in close contact with the first protrusion 57.

  Here, the height difference between the upper end surface of the first upper edge portion 33 and the upper end surface of the third upper edge portion 38 (that is, the depth of the first upper edge portion 33 with respect to the third upper edge portion 38) is described as α. The thickness of the first protrusion 57 of the mounting spring 5 is described as β, and the length of the first hook 58 in the short direction (that is, the length of the first hook 58 in the substantially vertical direction) is γ. It describes. The height difference α, the thickness β, and the length γ satisfy the relationship β ≦ α <γ.

  Since β ≦ α, the first projecting portion 57 is flush with the third upper edge portion 38 or positioned below the third upper edge portion 38. Therefore, the first protrusion 57 does not protrude from the third upper edge 38. As a result, the posture of the lamp body 1 is stabilized. Further, since α <γ, it is possible to prevent the first flange portion 56 from coming off from the first upper edge portion 33.

  With reference to FIG.1, FIG.4, FIG.6 and FIG. 7, the reflection member 7, and the member and site | part relevant to the reflection member 7 are demonstrated. As shown in FIGS. 1 and 4, the reflecting member 7 has a frustoconical reflecting portion 8. A part of the light emitted from the light emitting element array 28 and diffused by the diffusion member 27 is reflected by the reflecting portion 8. At least the reflecting portion 8 of the reflecting member 7 is preferably subjected to reflection processing such as white coating, silver coating, or glossy metal plating in order to efficiently reflect the light diffused by the diffusing member 27. . The material of the reflecting member 7 may have a color with high light reflectance such as white or silver. For example, the reflecting member 7 is a reflecting mirror.

  As shown in FIG. 4, the luminaire 100 further includes a plurality of fixing springs 21 that fix the reflecting member 7 to the frame 3. In addition, in this embodiment, although the lighting fixture 100 is provided with the two fixed springs 21, the number of the fixed springs 21 should just be two or more. As shown in FIG. 6, the two second upper edge portions 36 of the frame 3 are formed corresponding to the two fixing springs 21. The number of the second upper edge portions 36 can be set to an arbitrary number depending on the number of the fixing springs 21.

  As shown in FIG. 7, the fixed spring 21 is bent in a substantially V shape and has a distal end portion 61 and a proximal end portion 62. The base end portion 62 has a substantially U-shaped cross section and sandwiches the second upper edge portion 36. Further, a first claw portion 63 is formed at the base end portion 62, and the first claw portion 63 is hooked on the concave portion 37 of the second upper edge portion 36. As a result, the fixing spring 21 is fixed to the frame body 3. The two fixing springs 21 face each other. The reflection member 7 (FIG. 4) is inserted into the frame 3 from below the frame 3 while elastically deforming the fixed spring 21 against the elastic force of the fixed spring 21. As a result, the outer wall surface of the reflecting member 7 is urged by the two tip portions 61 of the two fixing springs 21, and the reflecting member 7 is fixed inside the frame 3.

  With reference to FIG. 10, the attachment to the building of the lighting fixture 100 is demonstrated. FIG. 10 is a cross-sectional view showing the lighting fixture 100 attached to a building. In addition, in FIG. 10, the cross section of board RB as a frame 3, the attachment spring 5, and the ceiling is shown. Moreover, about the lamp main body 1 and the reflection member 7, the simplified side surface is shown.

  The three attachment springs 5 fix the frame 3 to the board RB, whereby the lighting fixture 100 is attached to the board RB. Specifically, the board RB is formed with a circular mounting hole RH corresponding to the shape of the frame 3. The mounting hole RH is formed at the mounting position of the frame 3, that is, the mounting position of the lighting fixture 100 in the board RB. The diameter of the mounting hole RH is larger than the diameter of the frame body 3 and smaller than the diameter of the flange portion 32.

  The luminaire 100 is inserted into the mounting hole RH until the collar portion 32 comes into contact with the board RB. The board RB is strongly sandwiched between the three attachment springs 5 and the flange portion 32 by the elasticity of each attachment spring 5. Therefore, the frame 3 is fixed to the board RB. As a result, the lighting fixture 100 is attached to the board RB.

  As described above with reference to FIGS. 7 and 8, according to the present embodiment, the attachment spring 5 has the inner arm portion 53, and the second portion of the frame body 3 passes through the inside of the frame body 3. 1 is supported by the upper edge 33. Therefore, the attachment spring 5 can be attached to the frame body 3 with a simple structure without forming a spring attachment portion having a complicated structure as in the prior art on the frame body 3.

  Moreover, according to this embodiment, since the attachment spring 5 has the inner arm part 53, compared with the case where a spring attachment part is formed in the outer wall of the frame like the past, the frame 3 The movement of the mounting spring 5 in the radial direction is not easily restricted by the frame body 3. That is, in this embodiment, the lighting fixture 100 is provided with a relief of the attachment spring 5 in the radial direction of the frame 3. The radial direction of the frame body 3 is a direction orthogonal to the center line of the frame body 3 and indicates a direction from the outside of the frame body 3 toward the center line of the frame body 3.

  Since the escape of the mounting spring 5 is provided, the mounting spring 5 is pushed into the frame 3 according to the processing variation of the inner diameter of the mounting hole RH when the lighting apparatus 100 is mounted, and from the mounting spring 5 to the board RB. Can be adjusted in accordance with the processing variation of the inner diameter of the mounting hole RH. Therefore, even if the processing variation of the inner diameter of the mounting hole RH occurs, it is possible to secure the mounting strength of the lighting fixture 100 while suppressing the breakage of the board RB. In particular, as described with reference to FIG. 9, by providing play to the first end portion 51 of the mounting spring 5, the escape of the mounting spring 5 functions more effectively.

  In general, the mounting hole RH is not opened and processed in the board RB manufacturing factory. After the board RB is constructed on a building such as a house, an operator such as a carpenter or a lighting equipment contractor The mounting hole RH is opened and processed manually using a tool. Since it is a manual operation, there is a possibility that the inner diameter of the mounting hole RH varies, or the mounting hole RH does not become a perfect circle. In the present embodiment, due to the escape of the mounting spring 5, the processing variation of the inner diameter of the mounting hole RH due to manual operation can be absorbed, and the lighting fixture 100 can be mounted on the board RB with appropriate strength.

  Moreover, since the escape of the attachment spring 5 is provided, the attachment spring 5 is pushed into the inside of the frame 3 according to the property of the board RB (for example, the thickness and material of the board RB) when the lighting apparatus 100 is attached. Thus, the pressing force from the mounting spring 5 to the board RB can be adjusted according to the nature of the board RB. Therefore, for each board RB having a different property, the mounting strength of the lighting apparatus 100 can be increased while suppressing breakage of the board RB without preparing the mounting spring 5 having a different property (for example, shape, material, dimension, elasticity, etc.). It can be secured. In particular, as described with reference to FIG. 9, by providing play to the first end portion 51 of the mounting spring 5, the escape of the mounting spring 5 functions more effectively.

  Furthermore, according to the present embodiment, the relief of the mounting spring 5 can be easily provided by forming the opening 31 in the frame body 3. In the present embodiment, the attachment spring 5 is pushed into the inside of the frame body 3 through the opening 31 when attaching the lighting fixture 100. Further, by providing the opening 31, the inner arm portion 53 can be easily positioned inside the frame body 3.

  Furthermore, according to the present embodiment, the mounting spring 5 is attached to the frame body 3 with a simple structure by sandwiching the first end 51 of the mounting spring 5 between the lamp body 1 and the first upper edge portion 33 of the frame body 3. Attach to. As a result, since it is not required to attach the mounting spring 5 to the frame 3 with screws, it is possible to reduce the number of parts and the number of assembly steps, thereby reducing the cost.

  Furthermore, according to the present embodiment, the first spring 56 is formed on the attachment spring 5. Therefore, the attachment spring 5 can be easily temporarily fixed to the frame 3 by hooking the first flange 56 on the first upper edge 33 of the frame 3. By making the attachment spring 5 temporarily fixable, the assembling work of the luminaire 100 can be facilitated.

  Further, as described with reference to FIG. 5, according to the present embodiment, the width W <b> 1 of the inner arm portion 53 is smaller than the width W <b> 2 of the outer arm portion 54. Since the inner arm portion 53 is thinner than the outer arm portion 54, the attachment spring 5 can be easily bent when the lighting fixture 100 is attached. Therefore, the lighting fixture 100 can be easily inserted into the mounting hole RH, and the mounting operation of the lighting fixture 100 is facilitated. In addition, since the outer arm portion 54 is thicker than the inner arm portion 53, the mounting strength of the lighting fixture 100 can be secured by a strong elasticity.

  Furthermore, as described with reference to FIGS. 5 and 6, the width W <b> 5 of the opening 31 is larger than the width W <b> 1 of the inner arm portion 53 and the coupling portion 55 and smaller than the width W <b> 2 of the outer arm portion 54. Therefore, the outer arm portion 54 can be prevented from entering the inside of the frame body 3, and the lighting apparatus 100 can be attached to the board RB by the elasticity of the attachment spring 5.

  Next, with reference to FIGS. 11-14, the 1st modification-a 3rd modification of embodiment of this invention are demonstrated.

The attachment spring 5 according to the third modified example is that the attachment spring 5 shown in FIG. 4 is formed in that an engagement hole 65 is formed in the outer arm portion 54 when the first flange portion 56 has the second flange portion 66. The structure is different.

  A second flange 66 is formed at the lower end of the first hook 58. The second flange 66 includes a second protrusion 67 and a second hook 68. The second projecting portion 67 projects from the front end of the first hook portion 58 to the second end portion 52 side by bending approximately 90 degrees. The second hooking portion 68 is bent by approximately 90 degrees and protrudes from the tip of the second protruding portion 67 toward the coupling portion 55. The second hooking portion 68 and the inner arm portion 53 are substantially plane parallel. An engagement hole 65 is formed in the inclined portion 59 of the outer arm portion 54 so as to correspond to the second flange portion 66. In the present embodiment, the engagement hole 65 has a rectangular shape.

  FIG. 14 is a cross-sectional view illustrating a lighting fixture 100 according to a third modification. In FIG. 14, the frame 3 to which the lamp body 1 is fixed is shown, and for the sake of simplification of the drawing, the oblique lines indicating the cross section of the mounting spring 5 and the reflecting member 7 (FIG. 4) are omitted. First, before inserting the luminaire 100 into the mounting hole RH, the second hooking portion 68 of the second flange 66 is engaged with the engaging hole 65. When the lighting fixture 100 in which the second hooking portion 68 is engaged with the engagement hole 65 is inserted into the attachment hole RH, the attachment spring 5 comes into contact with the board RB.

  When the luminaire 100 is further moved in the insertion direction (that is, the substantially vertical direction toward the back of the ceiling) from the state in which the mounting spring 5 is in contact with the board RB, the bent portion 60 of the mounting spring 5 is indicated by the arrow A1 by the board RB. It is pushed in the direction (that is, the substantially horizontal direction toward the frame 3). When the bent portion 60 is pushed in the direction indicated by the arrow A1, the inclined portion 59 and the vicinity thereof are lowered in the direction indicated by the arrow A2 (that is, the substantially vertical direction toward the collar portion 32), and the engagement hole 65 is accompanied with the downward movement. Descends in the direction indicated by arrow A2. When the inclined portion 59 is lowered until the lower end of the engaging hole 65 is positioned below the lower end of the second hooking portion 68, the second hooking portion 68 can be detached from the engaging hole 65, and the outer arm portion 54 is not deformed. As the shape is restored, the second hooking portion 68 is disengaged from the engagement hole 65. As a result, as shown by a two-dot chain line in FIG. 14, the board RB is sandwiched between the attachment spring 5 and the flange 32, and the lighting apparatus 100 is attached to the board RB.

  According to the third modification of the present embodiment, the outer arm portion 54 can be temporarily fixed with a simple structure by hooking the second flange portion 66 in the engagement hole 65. Therefore, the luminaire 100 can be easily inserted into the mounting hole RH. As a result, the attachment work of the lighting fixture 100 becomes easy.

  The embodiment of the present invention has been described above with reference to the drawings (FIGS. 1 to 14). However, the present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes without departing from the gist thereof (for example, (1) to (4) shown below) )). In order to facilitate understanding, the drawings schematically show each component as a main component, and the thickness, length, number, and the like of each component shown in the drawings are different from the actual for convenience of drawing. In some cases. Moreover, the shape, dimension, etc. of each component shown by said embodiment are an example, Comprising: It does not specifically limit, A various change is possible in the range which does not deviate substantially from the effect of this invention.

  (1) As long as the attachment spring 5 has the inner arm portion 53, the shape of the attachment spring 5 is not limited to the shape shown in FIG. The first hook 58 may not be provided on the attachment spring 5. The frame 3 is not limited to a cylindrical shape, and may be a polygonal cylindrical shape, for example. The heat sink 9 may not be provided in the lamp body 1.

  (2) Although the opening 31 is provided in the frame body 3 and the inner arm portion 53 is positioned inside the frame body 3, the configuration in which the inner arm portion 53 is positioned inside the frame body 3 is not particularly limited. For example, a part of the flange portion 32 of the frame body 3 may be cut out and the inner arm portion 53 may be positioned inside the frame body 3 via the lower edge of the frame body 3.

  In this modification, the outer shape of the lamp body 1, in particular, the outer diameter of the frame 3 can be increased, and the degree of freedom in design is increased. That is, in this modification, since the mounting spring 5 is hardly disposed on the outer wall surface 34 of the frame 3, the outer diameter of the frame 3 can be increased so as to reduce the gap between the mounting hole RH and the frame 3. . By increasing the outer diameter of the frame body 3, the internal space of the frame body 3 can be expanded. Therefore, the degree of freedom of arrangement of components and / or members housed in the frame 3 can be increased, and the opening inner diameter of the reflecting member 7 can be increased.

  (3) A combination of the first modification and the second modification, a combination of the first modification and the third modification, a combination of the second modification and the third modification, and a first modification and the second. A combination of the modification and the third modification is also possible.

  (4) The light irradiation direction of the light source unit 11 is constant, but may be variable. For example, the lighting fixture 100 may be a universal downlight. In this case, the frame body 3 rotatably supports the lamp body 1. Therefore, the light irradiation direction of the light source unit 11 can be changed by rotating the lamp body 1.

  Even in this modified example, since the escape of the mounting spring 5 is provided, even when a load in the rotational direction is applied to the frame 3 when the lamp body 1 is rotated, the mounting spring 5 The pressing force from the mounting spring 5 to the board RB can be adjusted according to the load. As a result, the mounting strength of the lighting fixture 100 can be ensured while the breakage of the board RB is suppressed by the mounting spring 5.

  The present invention can be used in the field of lighting fixtures attached to buildings.
