The recess 22 has a square bottom 22a that closes the front side of the instrument main body 21, and an outer wall 22b that is approximately U-shaped in cross section and is formed around the bottom 22a. The outer wall portion 22b has a pair of side wall portions 22b1 and 22b1 forming both ends in the width direction. The side wall portion 22b1 has a screw hole 26, which is a through hole, in the middle of the vertical direction. The screw hole 26 has a screw groove formed on its inner surface in the thickness direction of the side wall portion 22b1. A screw member 26 is screwed into the screw hole 26 . The screw member 26 is, for example, a set screw with a hexagonal socket and does not have a screw head. Threads are formed on the outer surface of the screw member 26. A screw member other than a set screw with a hexagonal hole may be used, for example, a set screw with a slot or a screw with a head portion. Although the details will be described later, the instrument main body 21 is attached to the attachment member 71 by the screw member 26.

The protrusion 23 is an example of a second protrusion in the present invention. The protrusion 23 is a portion that protrudes from the bottom 22a of the recess 22 toward the mounting member 71 (rear side). The protrusions 23 are arranged at both ends of the recess 22 in the width direction. The protrusion 23 is disposed approximately in the center of the recess 22 in the vertical direction. The protruding portion 23 is a flat rib that extends inward in the left-right direction from the side wall portion 22b1.

The light source holding member attachment portion 24 is a boss provided below each of the pair of protrusions 23 and 23 and convex toward the attachment surface side (rear side). The light source holding member attachment portion 24 is formed to correspond to the extending portion 47 of the light source holding member 44 . The extending portion 47 of the light source holding member 44 is attached to the light source holding member attaching portion 24 with an attaching member 48 such as a screw.

The light guide member locking portion 25 is an eave-shaped portion provided at the lower end of the instrument main body 21. The light guide member locking portion 25 is provided in a straight line across the width direction of the instrument main body 21. A locking portion 62 of a light guide member 61 is locked to the light guide member locking portion 25, and the light guide member 61 is positioned with respect to the instrument body 21.

The power supply section 31 is a power supply device for supplying power to the LED element 42 included in the light source section 41 and lighting the LED element 42 . The power supply unit 31 includes a substantially rectangular parallelepiped insulating case that houses a power circuit in which a plurality of electronic components are mounted on a rectangular printed wiring board, and a power supply case that covers the power circuit. It has 32. The power supply case 32 has extensions 32a and 32b extending in the left-right direction from part of the end of a bottomed box-shaped portion that covers the periphery of the power supply circuit. The extending parts 32a and 32b are attached to the power supply case mounting parts 22a2 and 22a3, which are bosses provided at the bottom 22a of the recess 22 and projecting toward the mounting surface (rear side), respectively, with mounting members such as screws. It is attached. The power supply section 31 is attached to a position overlapping a power supply holding section 22a1 provided at the bottom 22a of the recessed section 22 and protruding toward the attachment surface side (rear side). Thereby, the position of the power supply circuit housed in the power supply case 32 in the front and back direction is regulated and rattling is suppressed. The power supply section 31 is for converting an alternating current supplied from an external commercial power source via wiring into a predetermined direct current, and supplying the converted current to the LED element 42. The power supply section 31 is electrically connected to the terminal block 35 via wiring. The terminal block 35 is attached to a terminal block attachment part 22a4 provided at the bottom 22a of the recess 22 and convex toward the attachment surface side (rear side). The terminal block 35 is arranged adjacent to the power supply section 31. The power supply unit 31 and the terminal block 35 are arranged in an area above the protrusions 23 and 23 on the bottom portion 22a. For example, when attaching the lighting fixture 11 to the wall surface W, the wiring extending from the terminal block 35 may be connected to the wiring for an external commercial power source (not shown) extending through the through hole 79 of the mounting member 71 previously attached to the wall surface W. The power supply section 31 is electrically connected to an external commercial power source. The power source section 31 and the light source section 41 are electrically connected by wiring.

The light source section 41 is a portion of the lighting fixture 11 that emits light downward. The light source section 41 is a module board that has a light emitting element that is a light source. The light source section 41 includes a substrate 43 processed into a flat plate shape (horizontally long shape), and a plurality of LED elements 42, which are point light sources, arranged in the longitudinal direction of the substrate 43 at equal intervals and in a substantially straight line. It was arranged as follows. Note that in this embodiment, a plurality of LED elements are used as a 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 substrate 43 is disposed in contact with the flat portion 45 of the light source holding member 44, and is attached to the light source holding member 44 together with the diffusion member 51 by a mounting member 60 such as a screw. The substrate 43 is electrically connected to the power supply section 31 by wiring.
Note that the substrate 43 may be attached to the flat portion 45 of the light source holding member 44 via a thermally conductive sheet or heat dissipation grease, thereby achieving higher heat dissipation.
Further, in this embodiment, one module board is used as the light source section 41, but this is not particularly limited, and the light source section may be configured with a plurality of module boards.

The light source holding member 44 is a metal member for holding the light source section 41, the diffusion member 51, and the light guide member 61 at predetermined positions of the instrument body 21. The light source holding member 44 has an L-shape in cross section. For example, the light source holding member 44 is formed by bending a plate-shaped steel plate. The light source holding member 44 has a flat portion 45 that is substantially rectangular in plan view, a vertical plate portion 46, and extending portions 47. The flat part 45 is a part for attaching the light source part 41, and is attached with a mounting member 60 such as a screw with the substrate 43 of the light source part 41 in contact with the lower surface. Thereby, the light source section 41 is arranged below the flat section 45. Since the light source holding member 44 also has a heat dissipation function of transmitting heat generated in the light source section 41 and emitting it to the outside, the flat section 45 that the light source section 41 comes into contact with is designed so that the contact area with the light source section 41 is wide. It is formed flat.

The vertical plate portion 46 is a plate-shaped portion that extends downward from the rear end of the flat portion 45 in the transverse direction (front-back direction in FIG. 4). The vertical plate portion 46 is a generally rectangular plate portion when viewed from the front. The vertical plate portion 46 holds the light guide member 61 by coming into contact with the cutout surface 61c of the light guide member 61 via the holding member 50.

The extending portion 47 is a plate-shaped piece that extends upward from near the front end of the flat portion 45 in the width direction at both ends of the flat portion 45 in the width direction. The extending portion 47 is attached to the light source holding member attaching portion 24 of the instrument body 21 with an attaching member 48 such as a screw. As shown in FIG. 4, the light source holding member 44 is attached to the instrument main body 21 so as to cover the upper and rear sides of the light source section 41 and the diffusion member 51 in a cross-sectional view.

As shown in FIG. 8, the diffusion member 51 has an approximately rectangular parallelepiped outer shape. The diffusion member 51 has a box shape with a bottom and is attached to the light source holding member 44 so as to cover the lower part of the light source section 41 (LED element 42) arranged on the flat part 45 of the light source holding member 44. The diffusion member 51 is an example of a module cover that covers the light source section 41 (module board). The diffusion member 51 has a bottomed box-like cover part 52 that covers the light source part 41, and flange parts 53 at both ends in the longitudinal direction. The flange portion 53 has a cutout portion 54 that is U-shaped in plan view (see FIGS. 8 and 9). The diffusion member 51 is attached to the light source holding member 44 via the notch 54 with an attachment member 60 such as a screw. The diffusion member 51 is a translucent member that reflects and diffuses the light from the light source section 41 (LED element 42). The diffusion member 51 is made of, for example, a transparent resin material. The diffusion member 51 prevents dust from adhering to the LED element 42.
In this embodiment, the diffusion member 51 having an approximately rectangular parallelepiped outer shape is used, but the shape is not particularly limited to this shape. For example, the diffusion member may have a dome shape or a semicircular shape when viewed in cross section.

As shown in FIGS. 4, 11, and 12, the diffusion member 51 has an opposing surface 55 that faces the light source section 41 (module board) within the cover section 52. As shown in FIGS. The opposing surface 55 has a flat portion 56 in a region on the front side of the opposing surface 55 in the front-rear direction, and a light control section 57 in a region on the rear side of the opposing surface 55 in the front-rear direction.

The flat portion 56 is a portion that overlaps a part of the LED element 42 (front side in the front-rear direction) in plan view, and is a flat entrance surface into which the light emitted from the LED element 42 enters. The light control portion 57 is a portion that overlaps with the other portion of the LED element 42 (on the rear side in the front-rear direction) in plan view. The light control portion 57 is formed on the rear side of the flat portion 56, and is a portion that is convex downward and has a sawtooth shape in cross section. The light control section 57 is provided in approximately half the area of the opposing surface 55 in the front-rear direction. The light control unit 57 distributes the light emitted from the LED element 42 in a direction further away from the optical axis L (towards the wall surface W).
Note that the outer surface of the cover portion 52 of the diffusion member 51 may be subjected to a light diffusion treatment such as texturing. Thereby, the graininess of the LED element 42 can be reduced and a more uniform light emitting surface can be realized.

The light guide member 61 is a substantially rectangular parallelepiped-shaped translucent member that guides the light emitted from the diffusion member 51 and emits it to the outside. The light guide member 61 is a translucent member that reflects and diffuses the light from the diffusion member 51 and controls the light distribution to the outside. The light guide member 61 is made of a transparent resin material having light-transmitting properties. The light guide member 61 is attached to the instrument main body 21 so as to cover the lower side of the diffusion member 51. The light guide member 61 has an entrance surface 61a, a front exit surface 61b, a cutout surface 61c, a rear exit surface 61d, a lower exit surface 61e, and a pair of side exit surfaces 61f. The entrance surface 61a is a flat surface that faces the light source section 41 via the diffusion member 51 and onto which light enters. The front emission surface 61b is a front portion of the light guide member 61 that is visible to the user, and is a flat surface from which light is emitted. The cutout surface 61c is a surface where the upper end corner of the light guide member 61 is cut out in an L-shape in a cross-sectional view, and is a surface from which light is emitted. The rear exit surface 61d is a surface facing the wall surface W, and is a flat surface from which light is emitted. The lower exit surface 61e is a flat surface that faces the entrance surface 61a and from which light that has entered the light guide member 61 exits. The pair of side emission surfaces 61e and 61e are the left and right side surfaces of the light guide member 61, and are flat surfaces from which light is emitted. The notch surface 61c is provided on the rear side of the upper end of the light guide member 61, and is held by the vertical plate portion 46 of the light source holding member 44 via the holding member 50. The light guide member 61 has a locking portion 62 on the front side of the upper end of the light guide member 61, which is locked to the light guide member locking portion 25 of the instrument body 21. The locking portion 62 is formed in a straight line across the width direction of the light guide member 61 . The light guide member 61 and the light source section 41 (module board) are arranged so as to sandwich the diffusion member 51 therebetween.

The light guiding member 61 has a light diffusing surface 64 on the side of the diffusing member 51 on which the light control section 57 is provided in the front-rear direction. Specifically, the light diffusing surface 64 of the light guide member 61 of this embodiment is formed on each outer surface of the entrance surface 61a, the notch surface 61c, the rear exit surface 61d, and the lower exit surface 61e. The light diffusing surface 64 is, for example, a textured surface that has been subjected to texture processing (frosted processing) in which fine irregularities are formed on the surface.
Note that although the light guide member 61 has a rectangular shape when viewed from the front as shown in FIG. 2, it may have another shape.

For example, when the light diffusing surface 64 is provided on the lower output surface 61e of the light guide member 61, the light that reaches the lower output surface 61e of the light guide member 61 is emitted from the light guide member 61 to the outside while being diffused. Therefore, light pooling is less likely to occur below the light guide member 61. Moreover, since a part of the light reaching the lower emission surface 61e is reflected, a more uniform light emission surface can be realized.
Further, when the light diffusing surface 64 is provided on the incident surface 61a of the light guide member 61, the graininess of the LED elements 42 can be reduced and a more uniform light emitting surface can be realized.

According to the above-described diffusion member 51 and light guide member 61, the light guide member 61 at least diffuses light on the side where the light control section 57 of the diffusion member 51 is provided in the front-rear direction (the rear side of the optical axis L). It has a surface 64. As a result, approximately half of the light emitted from the LED element 42 passes through the light control section 57 and enters the incident surface 61a of the light guide member 61 while spreading further outward (towards the wall surface W). Further, since the light incident on the light guide member 61 passes through the light diffusion surface 64 formed on the side where the light control section 57 of the light guide member 61 is provided (wall surface W side), the rear exit slope 61d A part of the light is reflected by the light diffusing surface 64 formed on the front side and travels forward. Thereby, when the lighting fixture 11 is viewed from the front, the front emission surface 61b can realize a more uniform light emission surface. Furthermore, since the light that enters the light guide member 61 without passing through the light control unit 57 travels inside the light guide member 61 without spreading as much as the light that passes through the light control unit 57, the lower side of the lighting fixture 11 can ensure sufficient illumination.
Note that in this embodiment, the light diffusing surface 64 is formed by texturing, but this is not particularly limited. For example, a light diffusing surface may be formed by performing a light diffusing treatment such as mixing a scattering agent. Further, in addition to the light guiding member 61, a light controlling member such as a reflecting member may be provided as appropriate.
Further, the shape of the light guide member 61 in this embodiment is merely an example, and may be hemispherical in plan view.

The attachment member 71 is a member for attaching the instrument body 21 to the wall surface W. The mounting member 71 is attached to the wall surface W using a mounting member such as a screw. The mounting member 71 mainly includes a mounting surface portion 72, protruding portions 73, a back plate 74, and a packing 75 which is an elastic member.

The mounting surface portion 72 has a horizontally long rectangular shape when viewed from the front. The mounting surface portion 72 is a plate-shaped member made of metal. The mounting surface portion 72 has a pair of ribs 77, 77, a pair of insertion holes 78, 78, and a through hole 79. The pair of ribs 77 extend linearly in the width direction at the upper and lower ends of the mounting surface portion 72 . By providing the pair of ribs 77, 77, the rigidity of the mounting surface portion 72 is increased and distortion of the mounting surface portion 72 is suppressed. As will be described in detail later, when the screw member 26 is screwed together to attach the instrument body 21, the attachment member 71 is pressed inward in the length direction. At this time, the presence of the pair of ribs 77 prevents the mounting surface portion 72 from deforming. The insertion holes 78 are holes through which a mounting member such as a screw for mounting the mounting member 71 to the wall surface W is inserted. The through hole 79 is a hole for drawing out wiring for an external commercial power source (not shown).

The protrusions 73 are examples of the first protrusions in the present invention. The protruding parts 73 are a pair of parts that protrude toward the instrument main body 21 near both ends of the mounting surface part 72 in the width direction. The protruding parts 73 are manufactured integrally with the mounting surface part 72 by die-casting. For example, the protrusions 73 are manufactured by die-casting an aluminum alloy (ADC12), which is relatively lightweight and has high rigidity, integrally with the mounting surface part 72. The protruding parts 73 have a base part 73a extending from the mounting surface part 72 toward the instrument main body 21 side, and an inclined surface part 73b that is spaced apart from the mounting surface part 72 as it extends diagonally outward in the width direction from the tip of the base part 73a. There is. The base portion 73a has a U-shape in cross section. The base 73a is a portion that is disposed below the protrusion 23 and supports the protrusion 23 when the instrument main body 21 is attached to the attachment member 71. The inclined surface portion 73b is a portion that is pressed by the tip of the screw member 26 when the screw member 26 is screwed into the screw hole 26 and the screw member 26 enters the instrument body 21.

The back plate 74 is a plate member having a horizontally long rectangular shape when viewed from the front and having slightly larger vertical and width dimensions than the mounting surface portion 72 . The back plate 74 is a member that covers the rear side (wall surface W side) of the power supply section 31 and the terminal block 35. The dimensions of the back plate 74 in the vertical direction and the width direction are smaller than the dimensions in the vertical direction and the width direction of the inner portion of the outer wall portion 22b, which is substantially U-shaped in cross section. The back plate 74 has openings at positions corresponding to the pair of insertion holes 78 and the through hole 79 of the mounting surface portion 72 . The back plate 74 is arranged on the back side of the mounting surface section 72, and is attached to the back side of the mounting surface section 72 with a mounting member such as a screw. Note that the back plate 74 can be changed as appropriate depending on the size of the instrument main body 21. By changing only the back plate 74, the mounting surface portion 72 can be made common, and it can also be made compatible with instrument bodies 21 of different sizes.
In addition, in this embodiment, although the attachment surface part 72 and the back plate 74 were provided as separate bodies, the present invention is not limited to this, and they can also be manufactured integrally.

The packing 75 is a rectangular elastic member that is approximately the same size as the instrument main body 21 when viewed from the front. The packing 75 has openings at positions corresponding to the pair of insertion holes 78 and the through hole 79 of the mounting surface portion 72 . The packing 75 is arranged on the back side of the back plate 74 and is attached to the back plate 74. By attaching the packing 75 to the back plate 74, the packing 75 is unlikely to be displaced when the attachment member 71 and the instrument main body 21 are attached. This prevents improper installation of the lighting fixture 11.
Note that the packing 75 is not an essential component. Depending on the indoor installation location, the structure may be such that the packing 75 is not used.

When attaching the lighting fixture 11 configured as described above to the wall surface W, first the mounting member 71 is attached to a predetermined position on the wall surface W using a mounting member such as a screw. Subsequently, the wiring for an external commercial power source (not shown) drawn out from the through hole 79 of the mounting member 71 and the wiring extending from the terminal block 35 are electrically connected. Subsequently, the instrument body 21 is temporarily attached to the mounting member 71 such that the pair of protrusions 23 of the instrument body 21 are disposed above the protrusion 73 of the mounting member 71. In this case, the tip 73c of the protrusion 73 is in a state separated from the bottom 22a of the instrument main body 21 (temporarily attached state) (see FIG. 7(a)). Subsequently, when the operator screws the screw member 26 into the screw hole 26 and further screws the screw member 26 into the screw hole 26 using a hexagonal wrench (not shown), the tip of the screw member 26 comes into contact with the inclined surface portion 73b. Subsequently, when the operator further screws the screw together using a hex wrench, the screw member 26 is inserted from the outside in the width direction of the instrument main body 21 toward the inside, and the tip of the screw member 26 touches the inclined surface portion 73b of the mounting member 71. While sliding, the instrument main body 21 is guided toward the wall surface W side. Subsequently, when the operator further screws the screw together using a hex wrench, the tip of the screw member 26 will be in a state of pressing the base 73a of the attachment member 71 inward in the width direction of the instrument body 21, and the base end of the screw member 26 is recessed into the screw hole 26 (attachment completed state), and the attachment work of the instrument body 21 to the attachment member 71 is completed (see FIG. 7(b)).

In the lighting fixture 11 according to the present embodiment described above, the screw member 1 is inserted from the outside in the width direction of the fixture main body 21 toward the inside, so that the tip of the screw member 1 touches the inclined surface portion 73b of the mounting member 71. While sliding, the instrument main body 21 is guided toward the wall surface W side. In this manner, in the lighting fixture 11, the fixture body 21 can be attached to the wall surface W while easily guiding the fixture body 21 to the mounting member 71 disposed on the wall surface W side.

Furthermore, since the lighting fixture 11 is configured such that the screw member 26 is inserted toward the inside in the width direction of the fixture body 21, the length dimension of the screw member 26 does not affect the thickness dimension of the fixture body 21. Thereby, a small and thin lighting fixture can be provided.

Furthermore, in the lighting fixture 11, the fixture body 21 is attached to the fixture body 71 with the tip of the screw member 26 pressing the base 73a of the fixture body 71 toward the inside in the width direction of the fixture body 21; The instrument main body 21 is securely fixed to the mounting member 71 without any rattling of the instrument body 21.

Further, in the lighting fixture 11, when the fixture main body 21 is attached to the mounting member 71, the protrusion 23, which is the second protrusion, is arranged above the protrusion 73, which is the first protrusion. As a result, the instrument main body 21 is vertically positioned relative to the mounting member 71, and the instrument main body 21 is stably held on the mounting member 71. Since the protrusion 73, which is the first protrusion, positions the instrument main body 21 in the vertical direction and fixes the instrument main body 21, the mounting member 71 can be made smaller. Thereby, a small-sized fixture main body can be attached, and a small-sized lighting fixture can be provided.

Furthermore, in the lighting fixture 11, the mounting member 71 has a mounting surface portion 72 to which a pair of protrusions 73 are attached to both ends in the width direction, and the upper end of the mounting surface portion 72 is formed in a linear shape. Further, the upper ends of the pair of protrusions 73 are provided at approximately the same distance from the upper end of the mounting surface portion 72 in the vertical direction. Thereby, by using the upper end surface of the mounting surface portion 72 as a reference, it is easy to mount the instrument main body 21 substantially horizontally without tilting in the vertical direction.

Furthermore, in the lighting fixture 11, the mounting surface portion 72 has ribs 77, 77 extending in the width direction at its upper and lower ends. In this way, by providing the ribs 77, 77, the strength of the mounting surface part 72 is increased, and when the instrument main body 21 is attached to the mounting member 71, the screw member 26 is attached to the mounting surface part 72 from the left and right direction via the protruding parts 73, 73. It is possible to prevent the mounting surface portion 72 from being distorted by the force of pressing against it.

The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 12). However, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the spirit thereof. Further, the shapes and the like shown in the above embodiments are merely examples and are not particularly limited, and various changes can be made without substantially departing from the effects of the present invention.
