The plate-shaped portion 201 has a rectangular shape that is long in the vertical direction when viewed from the front, and has a shape close to a rectangular shape when the device main body 7 is viewed from the front. The size of the rectangular shape when the plate-shaped portion 201 is viewed from the front is larger than the rectangular shape when the device main body 7 is viewed from the front.
The plate-shaped portion 201 has a rectangular region 207 located in the central portion and an annular region 209 located outside the rectangular region 207 and surrounding the rectangular region 207 when viewed from the front. The outer peripheral edge of the rectangular region 207 coincides with the inner peripheral edge of the tubular portion 203 when the cover body 9 is viewed from the front. The inner peripheral edge of the annular region 209 coincides with the inner peripheral edge of the tubular portion 203 when the cover body 9 is viewed from the front.

In particular, it will be described with reference to FIG.
The front surface 207a and the rear surface 207b of the rectangular region 207 have, for example, grain. The grain can be obtained, for example, by injection molding using a die that has been subjected to grain processing. A diffusing agent such as silicone is added to the resin constituting the cover body 9.
The uneven state of the front surface 207a of the rectangular region 207 is smaller than the uneven state of the rear surface 207b. In other words, the surface roughness of the rear surface 207b of the rectangular region 207 is larger (coarse) than the surface roughness of the front surface 207a. From the viewpoint of the degree of diffusion, the rear surface 207b has higher diffusivity than the front surface 207a. As a result, the light from the LED unit 5 can be diffused on the rear surface 207b, and uniform light can be emitted from the front surface 207a.

The front surface 209a of the annular region 209 is an uneven surface. The unevenness repeats triangular wavy irregularities in a cross section (for example, FIG. 10) orthogonal to the circumferential direction forming the annular region of the annular region 209. The unevenness is continuously projected from the inside to the outside in a triangular (isosceles triangle) shape while repeating in an annular shape with reference to the front surface 207a of the rectangular region 207 in the cross section. The rear surface 209b of the annular region 209 is a surface without wrinkles or a surface having wrinkles with small irregularities.

(2) Cylindrical part This will be described with reference to FIGS. 9 and 10.
When the cover body 9 is viewed from the front (see FIG. 2), the tubular portion 203 has a rectangular shape so as to surround the mounting portion 67 on which the LED unit 5 is mounted. The inner surface 203a of the tubular portion 203 has an uneven shape. The unevenness of the inner surface 203a extends in the front-rear direction and is continuously provided in the circumferential direction. The unevenness has the same triangular wavy shape as the unevenness provided on the front surface 209a of the annular region 209 of the plate-shaped portion 201. The size of the unevenness is the same as the unevenness on the inner surface of the tubular portion 203. The shape and size of the unevenness may be appropriately changed according to the light distribution characteristics of the light emitted from the lighting device 1.
The outer surface 203b of the tubular portion 203 has a grain. The size of the grain is about the same as the size of the grain on the front surface 207a of the rectangular region 207. The rear end of the inner surface 203a has a step 204 so as to fit into the step between the protrusion 79 and the groove 80 of the main body case 51.

(3) Mounting portion As shown in FIG. 2, the mounting portion 205 is attached to the peripheral portion 69 of the main body case 51 in a state of closing the opening of the front peripheral wall 63 of the main body case 51.
As shown in FIGS. 9 and 10, the mounting portion 205 has a rear contact portion 211 that contacts the peripheral portion 69 from the front side and a front of the main body case 51 when the rear contact portion 211 abuts on the peripheral portion 69. It has a front contact portion 213 that contacts the front end of the peripheral wall 63.

(3-1) Rear contact portion This will be described with reference to FIGS. 9 and 10.
The rear contact portion 211 is formed in an annular contact region 215 that contacts along the outer circumference of the groove 80 (see (a) of FIG. 7) of the main body case 51 and a region that extends in the vertical direction in the annular contact region 215. It has an overhang contact area 217 that overhangs and contacts the outside in the left-right direction.
The annular contact region 215 is provided so as to project outward from the outer peripheral surface of the tubular portion 203 (see also FIG. 2). The overhanging contact area 217 has a screw hole 219 that opens on the rear surface side. A screw body 78 (see FIG. 2) through which a through hole 77 (see FIG. 7A) is inserted is screwed into the screw hole 219 from the rear side of the mounting wall 61 of the apparatus main body 7. As a result, the cover body 9 is attached to the device main body 7.
The mounting portion 205 has an annular protrusion 220 that projects rearward from the inner peripheral side of the annular contact region 215. The annular protrusion 220 is inserted into the groove 80 of the main body case 51 (see (a) in FIG. 7). A packing 82 is fitted in the groove 80, whereby the cover body 9 is mounted on the apparatus main body 7 while maintaining high airtightness.

(3-2) Front contact portion This will be described with reference to FIGS. 9 and 10.

The unevenness here extends in the left-right direction and is continuously provided in the up-down direction. The unevenness has the same triangular wavy shape as the unevenness of the front surface 209a of the annular region 209 in the rectangular region 207.

6. Mounting the apparatus main body on the mounting body The description will be described with reference to (a) of FIG. 11 and (b) of the same figure.
First, as shown in FIG. 11A, the mounting body 3 is fixed to the outer wall (attached surface) around the entrance via the cushioning material 2. The device body 7 to which the cover body 9 is attached (in this item, the device body with the cover body is simply referred to as the “device body”) 7 is prepared, and the through holes 11 and 27 of the cushioning material 2 and the mounting body 3 are prepared. A power cable (not shown) derived from the above is connected to the terminal unit 59.
After that, the apparatus main body 7 is inclined so that the lower side approaches the attachment body 3, and the fixture 55 of the apparatus main body 7 is engaged with the upper surface of the attachment side inclined piece 25 of the attachment body 3. Then, the upper side of the device main body 7 is brought close to the mounting body 3, the rear upper wall 65a of the rear peripheral wall 65 of the device main body 7 is overlapped with the vertical piece 23 of the mounting body 3, and the through hole of the rear upper wall 65a of the device main body 7 is overlapped. The fixed body 4 is inserted through the 115 and screwed into the screw hole 34 of the mounting body 3. This state is shown in FIG. 11 (b). The alignment of the through hole 115 of the device main body 7 and the screw hole 34 of the mounting body 3 is performed in a state where the device main body 7 is slightly pushed toward the mounting body 3.

Next, when the fixed body 4 is screwed in the direction in which the fixed body 4 penetrates, the fixed body 4 descends in the direction of the arrow A shown in FIG. 11 (b). At this time, since the inclined surface 151 of the fixture 55 of the apparatus main body 7 and the inclined surface 35 of the attachment side inclined piece 25 of the mounting body 3 are inclined substantially in parallel, they move in the direction of the arrow B. As a result, the device main body 7 moves to the side to be mounted as shown by the arrow C.
The width of the cushioning material 2 in the left-right direction is slightly larger than the pair of inner side walls 81 of the device main body 7, and the upper end thereof is configured to slightly project from the rear upper wall 65a of the device main body 7. This is to improve the design by making the cushioning material 2 invisible when the lighting device 1 is mounted on the surface to be mounted and viewed from the side or the lower side of the device main body 7.
When the device main body 7 approaches the surface to be attached by the screwing of the fixed body 4, the rear upper wall 65a of the device main body 7 and the rear end faces of the pair of inner wall walls 81 press the cushioning material 2. As a result, the apparatus main body 7 is attached to the attachment body 3 in a pressure contact state with respect to the cushioning material 2.
In this way, the device body 7 to which the cover body 9 is mounted is mounted and fixed to the mounting body 3, and the fixture 55 of the device body 7 and the mounting side inclined piece 25 of the mounting body 3 are engaged and screwed by the fixing body 4. Because it is done by, the installation work is reduced.

7. Measures against rainwater (1) The connection between the front side cover body 9 and the front peripheral wall 63 of the apparatus main body 7 uses a step 204 as shown in FIGS. 3, 9 and the like. Therefore, it is possible to suppress the infiltration of rainwater from the joint portion. As shown in FIGS. 9 and 10, the annular contact region 215 of the mounting portion 205 in the cover body 9 projects outward from the outer peripheral surface (203b) of the tubular portion 203, and therefore penetrates into the inside of the cover body 9. It is possible to prevent the rainwater from being transmitted beyond the annular contact region 215 to the mounting wall 61 side of the main body case 51.
As shown in FIG. 3, the annular protrusion 220 on the rear end surface of the mounting portion 205 of the cover body 9 is inserted into the groove 80 of the main body case 51 into which the packing 82 is inserted. This also improves the sealing property.
As shown in FIG. 7A, the mounting portion 67 on which the LED unit 5 is mounted in the apparatus main body 7 is surrounded by a protrusion 79 inside the groove portion 80 in which the packing 82 is arranged over the entire circumference. , It is possible to suppress the transmission of rainwater to the mounting portion 67.

(2) Rear side portion As shown in FIG. 11B, the main body case 51 is attached to the mounting body 3 with the rear upper wall 65a and the rear end faces of the pair of inner side walls 81 pressing the cushioning material 2. .. Therefore, it is possible to prevent rainwater from entering the inside of the main body case 51.
Even if rainwater enters the rear side of the main body case 51, the main body case 51 has a drainage mechanism. That is, the apparatus main body 7 has a discharge path for discharging rainwater that has entered the main body case 51 to the outside of the main body case 51 on the outside of the circuit unit 53 and inside the rear peripheral wall 65.

Specifically, it has two types of drainage channels.
The first drainage channels D and E are composed of an outer surface of a pair of inner side walls 81, an inner surface of a pair of rear side walls 65c and 65d, an upper surface of an inclined wall 85, and a recess 87.
The second drainage channel F is composed of an inner surface of a pair of rear side walls 65c and 65d connected to the rear lower wall 65b, a rear surface of the mounting wall 61, an upper surface of the rear lower wall 65b, and a chipped portion 119.

Hereinafter, the drainage channels D, E, and F will be described with reference to FIG.
First, rainwater collected between the inner side wall 81 and the left and right rear side walls 65c and 65d forming the rear peripheral wall 65 flows down along the inner surface of the rear side walls 65c and 65d from the recesses 87 of the rear side walls 65c and 65d. It may be discharged to the outside (the path "D" in the figure), or it may flow down along the outer surface of the inner wall 81 and the upper surface of the inclined wall 85 (the path "E" in the figure). There is.) Instead of the recess 87, a through hole whose lower end is located on the upper surface of the inclined wall 85 can also be used.
Rainwater that has entered between the pair of inner side walls 81 via the cushioning material 2 and the like is transmitted through the rear surface of the mounting wall 61, the inner surface of the inner side wall 81, and the like, and is discharged from the chipped portion 119 of the rear lower wall 65b of the rear peripheral wall 65. (It is the route of "F" in the figure.). Instead of the chipped portion 119, a through hole penetrating the rear lower wall 65b can also be used.

8. Irradiation characteristics The light emission path of the lighting device 1 will be described with reference to FIG. Note that FIG. 13 shows the LED 121 and the cover body 9 instead of the entire lighting device. The light emitted from the LED 121 is emitted from the lighting device. The emission directions are the front indicated by the arrow H and the rear indicated by the arrow I.

Of the light incident on the rear surface 207b, the light refracted at the time of incident and directed toward the front surface 201a of the rectangular region 207 is emitted forward.
As shown by the arrow H3, a part of the light emitted from the LED 121 toward the tubular portion 203 is incident on the inner surface 203a of the tubular portion 203 and reflected in the tubular portion 203 to the rectangular region 207. It is guided and emitted forward from the front surface 207a.

(2) Of the light emitted from the rear LED 121 toward the rectangular region 207 and incident from the rear surface 207b, the light refracted at the time of incident and directed toward the annular region 209 is the annular region 209 as shown by the arrow I1. It is reflected by the front surface 209a having the unevenness of the above surface and is emitted rearward from the rear surface 209b.
As shown by arrow I2, a part of the light emitted from the LED 121 toward the tubular portion 203 is incident on the inner surface 203a of the tubular portion 203 and is guided to the annular region 209 while reflecting inside the tubular portion 203. Then, it is emitted rearward from the rear surface 209b.
In this way, by having the plate-shaped portion 201 larger than the tubular portion 203 when viewed from the front, it is possible to emit light to the rear as well.
