<First embodiment>
FIG. 1 is a perspective view showing a lighting fixture 1 according to the first embodiment from below. 2A and 2B are diagrams showing a configuration of the lighting fixture 1, FIG. 2A is a side view, FIG. 2B is a rear view, and FIG. 2C is a bottom view.
As shown in FIGS. 1 and 2, the lighting fixture 1 is used by supporting a fixture main body 10 on a support member 4 installed outdoors. The support member 4 is, for example, a pole-type support 5 erected on the ground beside a road such as a road shoulder, and supports the instrument body 10 at the tip 3 of the support 5.

The appliance main body 10 is formed of, for example, aluminum die casting, and is formed in a substantially rectangular shape in a plan view extending from the front end 11A to the rear end 11B. The appliance body 10 is supported by the distal end portion 3 of the column 5 near the rear end 11B, and is installed with the front end 11A facing the road (roadway side). An irradiation opening 12 is formed on the lower surface 10A of the instrument body 10 on the side of the front end 11A, and the irradiation opening 12 is covered with a transparent glove 13 having a flat plate shape.
In addition, the lower surface 10A of the instrument body 10 is provided with a column insertion hole 16 for inserting the column 5 near the rear end 11B. When supporting the instrument main body 10 on the support 5, the tip 3 of the support 5 is inserted into the support insertion hole 16 from the lower surface 10 </ b> A of the instrument main body 10.

The device main body 10 includes a case body 20 and a lower cover body 21. The case body 20 and the lower cover body 21 are formed of a material having corrosion resistance enough to withstand outdoor use and excellent heat conductivity, such as aluminum or an aluminum alloy. The case body 20 constitutes the upper surface 10C and the front, rear, left and right outer surfaces 10D, 10E, 10F, and 10G of the instrument body 10. The lower cover body 21 constitutes the lower surface 10A of the instrument body 10. An irradiation opening 12 is formed in the lower cover body 21, and a globe 13 is attached so as to close the irradiation opening 12. The device main body 10 has a structure in which the case body 20, the lower cover body 21, and the glove 13 are attached to each other in a watertight manner, and the internal space is waterproof.
A light source unit (not shown) and a power supply unit for supplying power to the light source unit are accommodated in an internal space of the instrument body 10 formed by the case body 20, the lower cover body 21, and the globe 13.

The light source unit is provided so as to be thermally connected to the case body 20 of the instrument body 10. Although not shown, the light source unit includes a plurality of light emitting elements such as COB LEDs as a light source, and the light source is directed downward. The light source unit may be configured to be attached to the back surface of the upper surface 10C. In addition, a power supply accommodating portion 80 is formed on the upper surface 10C so as to protrude toward the rear end 11B of the instrument body 10 and accommodates a power supply unit in an internal space. Note that the power supply unit may not be disposed inside the appliance main body 10 but may be disposed below the column 5.
The lower cover body 21 has a projecting portion 22 that projects the rear end 11B side of the instrument body 10 downward in a box shape, and the support hole 16 is formed substantially at the center of the projecting portion 22. In the internal space of the protruding portion 22, a connection fixing portion (not shown) for connecting and fixing the column 5 inserted through the column insertion hole 16 and the instrument body 10 is provided.

  The power supply accommodating portion 80 of the case body 20 and the projecting portion 22 of the lower cover body 21 are formed side by side in the vertical direction. As a result, the distal end portion 3 of the column 5 inserted in the column insertion hole 16 provided in the protruding portion 22 is disposed immediately below the power supply unit housed in the power supply housing 80. Therefore, the power supply line extending from underground through the inside of the support pillar 5 can be easily connected to the power supply unit housed in the power supply housing 80.

As shown in FIG. 2A, the upper surface 10 </ b> C of the instrument body 10 is inclined downward toward the column 5 so that the front end 11 </ b> A is located above the rear end 11 </ b> B. The upper surface 10C is desirably configured to be inclined at least 5 degrees, preferably 10 degrees or more with respect to the horizontal direction.
The device main body 10 is provided with a linear or thin rod-shaped guide member 30 extending downward from the peripheral edge 11C. A plurality of guide members 30 are provided at predetermined intervals along the periphery of the instrument body 10. The guide member 30 may be provided in a range of about two-thirds from the rear end 11 </ b> B in the front-back direction of the device main body 10.

  The guide member 30 is formed of a material such as stainless steel having excellent corrosion resistance, and a hydrophilic coating is applied to the surface thereof to form a hydrophilic member. Note that the guide member 30 may be formed from a hydrophilic material. The guide member 30 extends from the peripheral edge 11 </ b> C of the instrument body 10 toward the column 5, and is desirably connected to the surface of the column 5. The guide member 30 may be configured to be inserted into a connection hole provided on the surface of the column 5 and connected to the surface of the column 5, or may be joined to the surface of the column 5 by brazing or the like. It may be configured, or may be fixed by winding it around the column 5 or the like. The guide member 30 is installed so as to be inclined so that the angle from the vertical direction is 45 degrees or less.

By the way, as described above, the case body 20 of the instrument body 10 is formed of a material having excellent heat conductivity, and the light source unit is thermally connected to the case body 20. The heat is transmitted and radiated to the body 20, and the light source unit is maintained at a operable temperature. When the lighting fixture 1 is installed in an area where the amount of snow in winter is relatively large, the snow accumulated on the upper part of the fixture main body 10 is generated by heat transmitted from the light source unit to the fixture main body 10 or heat of sunlight. Melts and becomes water droplets. If the water droplets are exposed to cold and freeze when the water droplets are dropped from the upper surface 10C of the device main body 10, an icicle may be formed on the device main body 10.
In a conventional lighting fixture using a discharge lamp as a light source, the temperature of the fixture body 10 is high due to the high temperature of the discharge lamp, and water droplets dripping from the fixture body 10 are hard to freeze and icicles are hardly formed. On the other hand, when a light emitting element such as a COB LED is used as a light source, an amount of heat generated by the light emitting element is relatively small.

  The guide member 30 guides the thaw water from the upper surface 10 </ b> C of the instrument body 10 to the column 5, thereby preventing water drops of the instrument body 10 from dropping and suppressing the formation of an icicle in the instrument body 10. More specifically, since the upper surface 10C is inclined downward toward the column 5, when the snow accumulated on the upper surface 10C melts, the thaw water flows to the rear end 11B along the surface of the upper surface 10C. That is, the rear end 11B side of the upper surface 10C is configured as the water receiving portion 31 that receives the melting water. The plurality of guide members 30 extending from the peripheral edge 11 </ b> C of the device main body 10 are configured to extend from the water receiving portion 31. Thereby, the thaw water on the upper surface 10 </ b> C flows from the water receiving portion 31 along the guiding member 30. Since the guide member 30 extends toward the support 5 and is connected to the support 5, the meltwater flowing along the guide member 30 is guided to the surface of the support 5. Thereby, generation of an icicle in the instrument body 10 can be suppressed.

Further, each of the guide members 30 is installed so as to be inclined such that the angle from the vertical direction is 45 degrees or less. If the angle of the guide member 30 from the vertical direction is greater than 45 degrees, water droplets may drop from the guide member 30 itself. For this reason, by setting the angle of the guide member 30 from the vertical direction to 45 degrees or less, it is possible to prevent water droplets from dropping from the guide member 30 and to suppress generation of an icicle on the guide member 30. Can be. Further, since the guide member 30 is made hydrophilic, water can easily be guided to the support 5 through the guide member 30, and generation of an icicle from the guide member 30 can be prevented.
When the guide member 30 is provided only at the rear end 11B, an icicle may be generated from the side surfaces 10F and 10G of the instrument body 10. In the present embodiment, since a plurality of guide members 30 are provided along the peripheral edge of the device main body 10, the generation of icicles from the side surfaces 10F and 10G can be effectively suppressed.

  As shown in FIG. 3, a guide path 35 that guides water on the upper surface 10C may be formed in each guide member 30 on the upper surface 10C. The guide path 35 is formed by applying a hydrophilic coating to the upper surface 10 </ b> C of the instrument body 10. The guide path 35 is formed such that the width of the guide path gradually increases from the connecting portion 15 between the tool body 10 and the guide member 30 toward the center of the tool. Thereby, the water on the upper surface 10C is guided from the central part of the device toward each guiding member 30. Therefore, the water on the upper surface 10C can be guided from the guide path 35 to the guide member 30 and guided from the guide member 30 to the column 5, and the formation of an icicle from the instrument body 10 can be suppressed more effectively.

  The luminaire 1 can be used by supporting the luminaire main body 10 on the support pillar 5 or by supporting it on the wall surface 6 as the support member 4 as shown in FIG. The device main body 10 is supported such that the upper surface 10 </ b> C is inclined downward toward the wall surface 6, similarly to the case where the device main body 10 is used while being supported by the support 5. When the instrument main body 10 is supported and used on the wall surface 6, the guide member 30 extends from the peripheral portion 11 </ b> C of the instrument main body 10 toward the wall surface 6 and is connected to the wall surface 6. The water on the upper surface 10 </ b> C of the instrument body 10 is guided to the wall surface 6 by these guide members 30, so that generation of an icicle from the instrument body 10 is suppressed.
