The lamp 100 includes a main body part 110 and an angle 130 that is connected to the side part 114 of the main body part 110 and maintains the main body part 110 at a predetermined angle with respect to the column 10.

  The main body 110 includes a base member 111, a light source 112 connected to the base member 111, and a translucent cover 113 combined with the base member 111.

  The base member 111 is formed to extend with a V-shaped cross section. The base member 111 is positioned on the upper portion of the main body 110 in a state where the outdoor lighting fixture 1 is attached to the support column 10. The base member 111 includes an aluminum exterior part and electrical components arranged in the exterior part.

  The base member 111 is provided with a terminal connected to the light source 112, and the terminal is connected to an input line (not shown). The input line passes through the inside of the angle 130 from the side part 114 of the main body part 110 and is connected to a commercial power source installed in the column 10. In other words, electricity from the commercial power supply is supplied to the light source 112 connected to the terminal of the base member 111 via the input line.

  In the present embodiment, the light source 112 is an LED (Light Emitting Diode). However, the light source 112 is not limited to an LED, and an HID (High Intensity Discharge) lamp may be used.

  The translucent cover 113 is fitted with the exterior part of the base member 111 to form the outer shape of the main body part 110. The translucent cover 113 is formed to extend in a V-shaped cross section. The translucent cover 113 is positioned below the main body 110 in a state where the outdoor lighting fixture 1 is attached to the support column 10.

  In order to efficiently illuminate with the light emitted from the light source 112, the main body 110 is maintained at a predetermined angle with respect to the column 10. Specifically, the main body 110 is maintained at a predetermined angle with respect to the support 10 by adjusting the fixing angle between the arm 131 and the mounting bracket 132 and fixing the arm 131 to the support with the band 20. .

  In the main body 110 in a state maintained at a predetermined angle, the side closer to the support column 10 is located on the lower side in the vertical direction than the far side. In other words, the main body 110 is arranged so as to be inclined so that the height decreases as it approaches the support column 10. Therefore, the height of the lower end 115 of the translucent cover 113 on the column 10 side is lower than the height of the lower end 116 at the position farthest from the column 10.

  In this way, when rain or snow falls on the outdoor lighting device 1 attached to the support column 10, the rain or snow melting water adhering to the main body 110 travels down the outer surface of the main body 110 and has the lower end 115 at the lowest position. Get to Further, since the translucent cover 113 is formed to extend in a V-shaped cross section, water droplets are liable to accumulate at the lower end 115 of the main body 110, and when the outside air temperature is low, the water droplets are solidified and become icicles. It becomes.

  In the outdoor lighting fixture 1 according to the present embodiment, a drainage cover 140 whose upper surface functions as a drainage channel is disposed at a lower end 115 that is an end portion on the angle 130 side of the main body 110 and a position below the angle 130. Yes.

  The upper surface portion 142a and the upper surface portion 142b, and the upper surface portion 142c and the upper surface portion 142d intersect each other at an acute angle. In other words, the upper surface of the drainage cover 140 is formed in a groove shape having a V-shaped cross section. As a result, a valley 141 is formed on the upper surface of the drainage cover 140.

  A standing portion 143a and a standing portion 143b for attaching the drainage cover 140 to the arm portion 131 are provided so as to face each other from the upper end of the upper surface portion 142a and the upper end of the upper surface portion 142b. Holes 144a and 144b are formed at positions corresponding to the holes 134 of the arm part 131 in each of the standing part 143a and the standing part 143b.

  In this embodiment, the drainage cover 140 is produced by bending a metal sheet metal, but it may be produced by molding a resin.

  Both the arm portion 231 and the mounting bracket 232 are formed by bending a metal sheet metal. By changing the fixing angle between the arm portion 231 and the mounting bracket 232, the angle of the main body portion 110 with respect to the support column 10 can be adjusted.

  In order to efficiently illuminate with the light emitted from the light source 112, the main body 110 is maintained at a predetermined angle with respect to the column 10. Specifically, the main body 110 is maintained at a predetermined angle with respect to the support 10 by adjusting the fixing angle between the arm 231 and the mounting bracket 232 and fixing the arm 231 to the support with a bolt (not shown). Let

  In the main body 110 in a state maintained at a predetermined angle, the side closer to the support column 10 is located on the lower side in the vertical direction than the far side. In other words, the main body 110 is arranged so as to be inclined so that the height decreases as it approaches the support column 10. Therefore, the height of the lower end of the translucent cover 113 on the column 10 side is lower than the height of the lower end at the position farthest from the column 10.

  In the outdoor lighting fixture 2 according to the present embodiment, a drainage cover 240 whose upper surface functions as a drainage channel is disposed at an end of the main body 110 on the angle 230 side and a position below the angle 230.

  As shown in FIGS. 11 and 12, the drainage cover 240 has end portions on the angle 230 side of the main body 110 and upper surface portions 242 a and 242 b arranged below the angle 230.

  The upper surface portion 242a and the upper surface portion 242b intersect each other at an acute angle. In other words, the upper surface of the drainage cover 240 is formed in a groove shape having a V-shaped cross section. As a result, a valley 241 is formed on the upper surface of the drainage cover 240.

  As shown in FIG. 12, the drainage cover 240 has long hole portions 244a and 244b at positions facing each other. Further, the drainage cover 240 has inclined portions 245a and 245b that are substantially tapered in a plan view at one end.

  A flat portion 246 that is flat in a plan view and intersects the inclined portions 245a and 245b is provided at one end of the drainage cover 240. A corner portion 247a is formed at the intersection of the inclined portion 245a and the flat portion 246. A corner portion 247b is formed at the intersection of the inclined portion 245b and the flat portion 246.

  In this embodiment, the drainage cover 240 is produced by bending a metal sheet metal, but it may be produced by molding a resin.

  As shown in FIG. 10, in this embodiment, the drainage cover 240 is fixed to the mounting bracket 232 via the connecting bracket 270. The drainage cover 240 and the connection fitting 270 are fixed by a bolt 250 that is a fastening member. The connection fitting 270 and the attachment fitting 232 are fixed with bolts 280. The mounting bracket 232 has a female screw portion (not shown) that is screwed with the bolt 280.

  As shown in FIG. 13, the connecting fitting 270 includes a flat portion 271 that contacts the mounting fitting 232, orthogonal portions 272 a and 272 b that are bent from both ends of the flat portion 271 so as to be orthogonal to the flat portion 271, and an orthogonal portion 272 a. , 272b and folded portions 273a and 273b which are folded outward from each other and form an acute angle with the orthogonal portions 272a and 272b.

  In addition, the connecting metal fitting 270 has a protruding portion 274 that is bent from a part of the side surface of the flat portion 271 to the opposite side to the orthogonal portions 272a and 272b.

  Holes 275a and 275b through which the bolts 280 are inserted are formed in the plane portion 271. A female screw portion 276 that is screwed with the bolt 250 is formed in each of the folded portions 273a and 273b.

  The drainage cover 240 is fixed to the mounting bracket 232 while being attached to the connecting bracket 270. The protruding portion 274 of the connection fitting 270 is a member for preventing the drainage cover 240 from being attached to the attachment fitting 232 in the opposite direction.

  Specifically, the upper surface portion 242a and the folded portion 273a, and the upper surface portion 242b and the folded portion 273b are respectively arranged so that the flat portion 246 side of the drainage cover 240 is located on the protruding portion 274 side of the connecting metal fitting 270. The drain cover 240 and the connecting metal fitting 270 are fixed to each other by the bolts 250 while being in contact with each other.

  In this state, the connection fitting 270 and the attachment fitting 232 are fixed to each other with the bolts 280 so that the protruding portion 274 of the connection fitting 270 does not interfere with the attachment fitting 232. Thus, by fixing the drain cover 240 to the mounting bracket 232, the flat portion 246 of the drain cover 240 can always be positioned on the side facing the column 10.

  If it is attempted to fix the drainage cover 240 in the opposite direction to the mounting bracket 232, the projection 274 interferes with the mounting bracket 232, and the connecting bracket 270 and the mounting bracket 232 cannot be fixed with the bolt 280. Therefore, the assembly mistake of the outdoor lighting fixture 2 can be suppressed.

  As shown in FIG. 8, with the drainage cover 240 fixed to the angle 230, the upper surface of the drainage cover 240 faces the end of the main body 110 on the angle 230 side, and as it approaches the column 10, the vertical direction It extends to be located below.

  By attaching the drainage cover 240 as described above, water droplets collected at the end of the main body 110 on the angle 230 side drop on the upper surface of the drainage cover 240 and flow down to the column 10 side while gathering in the valley 241. . As a result, it is possible to suppress the growth of icicles at the position of the end of the main body 110 on the angle 230 side.

  In the present embodiment, a slight gap is provided between the end of the main body 110 on the angle 230 side and the upper surface of the drainage cover 240. However, if it is better to bring the end of the main body 110 on the angle 230 side and the upper surface of the drainage cover 240 into contact with each other in order to efficiently flow the water droplets, the end of the main body 110 on the angle 230 side. And the upper surface of the drainage cover 240 are brought into contact with each other.

  In the present embodiment, the flat portion 246 that is a part of the end portion of the drainage cover 240 is brought into contact with the support column 10 so that the water droplets that have flowed down the valley portion 241 flow to the ground surface through the support column 10. However, the drainage cover 240 and the support column 10 may not be in contact with each other.

  As described above, the main body 110 of the lamp 200 can be adjusted at a predetermined angle with respect to the column 10 by the angle 230. Therefore, the drainage cover 240 according to the present embodiment slides with respect to the main body 110 according to the interval between the end portion on the angle 230 side of the main body 110 and the support column 10 which is changed by adjusting the predetermined angle. It has a slide mechanism for moving.

  Specifically, when the main body 110 is adjusted so as to be orthogonal to the support 10, the interval between the end of the main body 110 on the angle 230 side and the support 10 is shortened. Therefore, the drain cover 240 and the support column 10 are prevented from interfering with each other by moving the fixing position of the drain cover 240 to the main body 110 side.

  The slide mechanism includes long hole portions 244 a and 244 b of the drainage cover 240, bolts 250, and a female screw portion 276 of the connection fitting 270. By changing the position of the bolt 250 in the long hole portions 244a and 244b along the long hole portions 244a and 244b, the drainage cover 240 can be slid relative to the main body portion 110.

  By this sliding mechanism, the drainage cover 240 can be slid relative to the main body 110 in accordance with a predetermined angle of the main body 110, and the drainage cover 240 can be prevented from interfering with the support column 10. The lengths of the long hole portions 244a and 244b are appropriately set according to a predetermined angle adjustment range of the main body 110.

  The inclined portions 245a and 245b are formed so that the support column 10 and the drainage cover 240 do not interfere with each other when the flat portion 246 of the drainage cover 240 is in contact with the support column 10. Accordingly, the inclined portions 245a and 245b are formed so that the inclined portions 245a and 245b do not interfere with the support column 10 even when the inclination angle of the main body 110 is the largest.

  Furthermore, the drainage cover 240 has corner portions 247a and 247b by having inclined portions 245a and 245b and a flat portion 246. A valley portion 241 is located between the corner portion 247a and the corner portion 247b.

  FIG. 14 is a partial bottom view of the state in which the support column and the corner portion of the drainage cover are in contact as viewed from below. When the drainage cover 240 is brought into contact with the support column 10 as shown in FIG. 14, the support column 10 and the inclined portions 245a and 245b of the drainage cover 240 come into contact with each other at the corners 247a and 247b.

  That is, the drainage cover 240 has corner portions 247 a and 247 b that are two contact portions that come into contact with the support column 10 in a state where a part of the inclined portions 245 a and 245 b are in contact with the support column 10. Between the corner portion 247a and the corner portion 247b, the lower end of the valley portion 241 that is the lowest portion of the upper surface is located.

  In this state, a gap is formed between the corner portion 247a and the corner portion 247b between the support column 10 and the flat portion 246. Due to this gap, the water droplets flowing down the valley 241 can be smoothly transmitted to the support column 10. Further, since dust or the like adhering to the drainage cover 240 can be discharged from the gap, it is possible to suppress the accumulation of dust or the like on the drainage cover 240 and causing poor drainage.

  In the present embodiment, the extending direction of the upper surface portions 242a and 242b of the drainage cover 240, that is, the angle formed by the extending direction of the valley portion 241 and the horizontal direction is set to 30 °. By setting the angle formed by the extending direction of the valley portion 241 and the horizontal direction to be 30 ° or more, the flow velocity of water droplets flowing down the valley portion 241 can be increased. Therefore, dust and the like accumulated on the drainage cover 240 can be discharged by the flow of water droplets flowing down the valley portion 241. As a result, it is possible to suppress the accumulation of dust or the like on the drain cover 240 to cause drainage failure.

  Further, the drain cover 240 may have a water repellent finish at least on the upper surface portions 242a and 242b. In this case, water droplets adhering to the upper surface portions 242a and 242b of the drainage cover 240 can be smoothly flowed down. As described above, by smooth drainage by the drainage cover 240, icing of water droplets can be suppressed and occurrence of icicles can be reduced.

  The drain cover 240 may be disposed at least at a position below the end of the main body 110 on the angle 230 side and the end of the angle 230 on the main body 110 side. By doing so, the position where the icicle is formed can be moved from the position of the lower end of the main body 110 to the column 10 even a little, so that the icicle falls on a passerby walking under the outdoor lighting fixture 2. Can be suppressed. Therefore, the influence of icicles can be suppressed.

  Of course, in each configuration in the first to third embodiments, it is naturally planned to combine those that can be combined.

  In addition, the said embodiment disclosed this time is an illustration in all the points, Comprising: It does not become a basis of limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims.
