The inner peripheral edge of the annular region 209 coincides with the inner peripheral edge of the cylindrical portion 203 when the cover body 9 is viewed from the front.

This will be particularly described with reference to FIG.
The front surface 207a and the rear surface 207b of the rectangular area 207 have, for example, a texture. The texture is obtained, for example, by injection molding using a textured mold. Note that 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 area 207 is configured to be smaller than the uneven state of the rear surface 207b. In other words, the surface roughness of the rear surface 207b of the rectangular area 207 is larger (rougher) than the surface roughness of the front surface 207a. From the viewpoint of the degree of diffusion, the rear surface 207b is more diffusive than the front surface 207a. Thereby, the light from the LED unit 5 can be diffused by 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. Concavities and convexities repeat triangular corrugations in a cross section (for example, FIG. 10) orthogonal to the circumferential direction constituting the annular shape of the annular region 209. The unevenness continuously protrudes in an annular shape from the inside to the outside in a circular manner from the inside to the outside when the front surface 207a of the rectangular region 207 is used as a reference in the cross section. The rear surface 209b of the annular region 209 is a surface having no wrinkles or a surface having small wrinkles.

(2) Cylindrical part It demonstrates using FIG.9 and FIG.10.
The cylindrical portion 203 has a rectangular shape that surrounds the mounting portion 67 on which the LED unit 5 is mounted when the cover body 9 is viewed from the front (see FIG. 2). The inner surface 203a of the cylindrical part 203 is uneven. The unevenness of the inner surface 203a extends in the front-rear direction and is provided continuously in the circumferential direction. The unevenness has the same triangular wave shape as the unevenness provided on the front surface 209 a of the annular region 209 of the plate-like portion 201. The size of the unevenness is the same as the unevenness of the inner surface of the cylindrical portion 203. Note that the shape and size of the unevenness may be changed as appropriate in accordance with the light distribution characteristics of the light emitted from the illumination device 1.
The outer surface 203b of the cylindrical part 203 has a texture. The size of the texture is about the same as the size of the texture on the front surface 207 a of the rectangular area 207. The rear end of the inner surface 203 a 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 Part The mounting part 205 is attached to the peripheral part 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 FIG.
As shown in FIGS. 9 and 10, the mounting portion 205 includes a rear contact portion 211 that comes into contact with the peripheral portion 69 from the front side, and a front portion of the main body case 51 when the rear contact portion 211 comes into contact with the peripheral portion 69. A front contact portion 213 that contacts the front end of the peripheral wall 63.

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

(3-2) Front Contact Part A description will be given with reference to FIGS. 9 and 10.
The front contact portion 213 is provided on the outer peripheral edge of the rear surface of the flange portion 221 that is provided in front of the rear contact portion 211 in the cylindrical portion 203 with a space therebetween. Here, the outer peripheral edge of the rear surface is a step, and is fitted to the front end of the front peripheral wall 63 of the apparatus body 7. The flange portion 221 is reinforced by a plurality of lateral ribs 225 provided on the outer periphery of the cylindrical portion 203.
The front surface 221a of the collar portion 221 is a surface without wrinkles. Concavities and convexities are provided on portions of the rear surface 221b of the flange portion 221 that are located on the left and right sides of the tubular portion 203. The unevenness | corrugation here is extended in the left-right direction, and is provided continuously in the up-down direction. The unevenness has the same triangular wave shape as the unevenness of the front surface 209 a of the annular region 209 in the rectangular region 207.

6). Attachment of the apparatus main body to the attachment body This will be described with reference to FIG. 11 (a) and FIG. 11 (b).
First, as shown in FIG. 11A, the attachment body 3 is fixed to the outer wall (attached surface) around the entrance via the cushioning material 2. An apparatus main body (in this item, the apparatus main body with the cover body is simply referred to as “apparatus main body”) 7 to which the cover body 9 is attached is prepared, and the shock absorber 2 and the through holes 11 and 27 of the attachment body 3 are prepared. A power cable (not shown) derived from is connected to the terminal unit 59.
Thereafter, 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 apparatus body 7 is brought close to the attachment body 3, the rear upper wall 65 a of the rear peripheral wall 65 of the apparatus body 7 is overlapped with the vertical piece 23 of the attachment body 3, and the through hole of the rear upper wall 65 a of the apparatus body 7 is formed. The fixed body 4 is inserted from 115 and screwed into the screw hole 34 of the mounting body 3. This state is shown in FIG. Note that the alignment between the through hole 115 of the apparatus body 7 and the screw hole 34 of the attachment body 3 is performed in a state where the apparatus body 7 is slightly pushed into the attachment body 3 side.

Next, when the fixed body 4 is screwed in the direction in which the fixed body 4 enters, it moves downward in the direction of arrow A shown in FIG. 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 attachment body 3 are inclined substantially in parallel, they move in the direction of arrow B. As a result, the apparatus main body 7 moves to the attached surface side as indicated by an arrow C.
The cushioning material 2 is configured such that the width in the left-right direction is slightly larger than the pair of inner side walls 81 of the apparatus main body 7, and the upper end slightly protrudes from the rear upper wall 65 a of the apparatus main body 7. This is to improve the design so that the cushioning material 2 is not visible when the state in which the lighting device 1 is attached to the surface to be attached is viewed from the side of the device body 7 or from below.
When the device main body 7 approaches the attached surface by screwing the fixed body 4, the rear upper wall 65 a of the device main body 7 and the rear end surfaces of the pair of inner side walls 81 press the cushioning material 2. Thereby, 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 mounting and fixing of the apparatus main body 7 to which the cover body 9 is attached to the mounting body 3 are engaged by the engagement between the fixture 55 of the apparatus main body 7 and the mounting-side inclined piece 25 of the mounting body 3 and the fixing body 4. Therefore, the installation work is reduced.

7. Measures against rainwater (1) Front portion The coupling between the cover body 9 and the front peripheral wall 63 of the apparatus body 7 uses a step 204 as shown in FIGS. For this reason, the intrusion of rainwater from the joint portion can be suppressed. Since the annular contact region 215 of the mounting portion 205 in the cover body 9 protrudes outward from the outer peripheral surface (203b) of the cylindrical portion 203 as shown in FIGS. 9 and 10, it enters the inside of the cover body 9. It is possible to suppress the rainwater that has passed through the annular contact region 215 from being transmitted 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 portion 80 of the main body case 51 in which the packing 82 is inserted. This also improves the sealing performance.
Since the mounting portion 67 for mounting the LED unit 5 in the apparatus main body 7 is surrounded by the protruding portion 79 inside the groove portion 80 in which the packing 82 is disposed as shown in FIG. It is possible to suppress rainwater from being transmitted to the mounting portion 67.

(2) Rear side part As shown in FIG. 11B, the main body case 51 is attached to the attachment body 3 with the rear upper wall 65 a and the rear end surfaces of the pair of inner side walls 81 pressing the cushioning material 2. . For this reason, it is possible to prevent rainwater from entering the 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, outside 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 the pair of inner side walls 81, an inner surface of the pair of rear side walls 65c and 65d, an upper surface of the inclined wall 85, and a recess 87.
The second drainage channel F includes 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, drainage channels D, E, and F will be described with reference to FIG.
First, rainwater accumulated between the inner side wall 81 and the left and right rear side walls 65c and 65d constituting the rear peripheral wall 65 flows down along the inner surfaces of the rear side walls 65c and 65d and from the concave portions 87 of the rear side walls 65c and 65d. It is discharged to the outside (the path of “D” in the figure), or it flows down along the outer surface of the inner wall 81 and the upper surface of the inclined wall 85 (in the path of “E” in the figure). Yes.) Instead of the recess 87, a through hole whose lower end is located just on the upper surface of the inclined wall 85 can be used.
Rainwater that has entered between the pair of inner side walls 81 via the cushioning material 2 or the like travels along the rear surface of the mounting wall 61, the inner surface of the inner side wall 81, etc., and is discharged from the notch 119 in the rear lower wall 65 b of the rear peripheral wall 65. (This is the route “F” in the figure.) Instead of the chipped portion 119, a through hole that penetrates the rear lower wall 65b can be used.

8). Irradiation Characteristics The light emission path of the illumination 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 outgoing directions are the front indicated by arrow H and the rear indicated by arrow I.

(1) Front The light emitted from the LED 121 toward the rectangular region 207 enters the rear surface 207b as indicated by an arrow H1. Of the light incident on the rear surface 207b, the light refracted at the time of incidence and directed toward the front surface 207a of the rectangular region 207 is emitted forward as it is.
A part of the light emitted from the LED 121 toward the cylindrical portion 203 is reflected by the inner surface 203a of the cylindrical portion 203 and enters the rectangular region 207 as indicated by an arrow H2. Of the light incident on the rear surface 207b, the light refracted at the time of incidence and directed toward the front surface 201a of the rectangular region 207 is emitted forward.
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 while being reflected in the rectangular region 207 as indicated by an arrow H3. It is guided and emitted forward from the front surface 207a.

(2) Back Of the light emitted from the LED 121 toward the rectangular region 207 and incident from the rear surface 207b, the light refracted at the time of incidence and directed toward the annular region 209 is, as indicated by the arrow I1, the annular region 209. It is reflected by the front surface 209a having the unevenness and is emitted backward from the rear surface 209b.
A part of the light emitted from the LED 121 toward the cylindrical portion 203 enters the annular region 209 while entering the inner surface 203a of the cylindrical portion 203 and reflecting inside the cylindrical portion 203 as indicated by an arrow I2. Then, the light is emitted rearward from the rear surface 209b.
Thus, by having the plate-like portion 201 larger than the tubular portion 203 when viewed from the front, light can be emitted backward.
