DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A street light according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is an enlarged sectional view of a main part of a street light according to an embodiment of the present invention. FIG. 1 shows a portion corresponding to the portion A of the street light shown in FIG.

As in FIG. 2, an upper glove 1 is attached to a lower glove 2 equipped with a lamp (not shown) so as to be openable and closable. Both gloves 1 and 2 are formed of resin or the like. As shown in FIG. 1, the upper glove 1 includes an opaque upper cover 3 provided at an upper portion and an opaque upper ring 4 provided at a lower portion. A bent portion 3a bent inward is formed at the lower end of the upper cover 3, and the bent portion 3a is placed on the upper surface of the upper ring 4 and fixed by bonding or the like. In addition, the waterproofness of the joint between the upper cover 3 and the upper ring 4 is maintained by the protrusion 4c protruding from the upper surface of the upper ring 4 as a cough. The lower glove 2 includes a light-transmitting lower cover 5 provided at a lower portion and a light-impermeable lower ring 6 provided at an upper portion. At the upper end of the lower cover 5, a stepped portion 5a having a notched outer surface is formed. The stepped portion 5a is fitted into a concave portion 6b provided at a lower portion of the lower ring 6, and is fixed by screwing or bonding. In addition, the waterproofness of the joint between the lower cover 5 and the lower ring 6 is maintained by the step 5a.
The reason why the upper cover 3 is opaque is that the street light does not need to distribute light upward because the lamp position is high. When the lamp position is low, the upper cover 3 may be translucent.

A lower protruding wall 4 provided on a lower surface of the upper glove 1 is provided at a detachable portion between the upper glove 1 and the lower glove 2.
a, an upper protruding wall 6a provided on the upper surface of the lower glove 2
And a space 10 formed between the lower protruding wall 4a and the upper protruding wall 6a. In this case, a lower protruding wall 4a is provided on the lower surface of the upper ring 4 so as to protrude downward and a lower end thereof is positioned close to the upper surface of the lower ring 6, and the lower protruding wall 4a is provided.
a protruding wall 6 projecting upwardly to the upper surface of the lower ring 6 inside the inner side of the upper ring 4 and having its upper end located close to the lower surface of the upper ring 4
The space 10 is formed between the lower protruding wall 4a and the upper protruding wall 6a, and the space 10 is large enough to prevent a capillary phenomenon. The upper surface of the lower ring 6, which is the lower portion of the space 10, is inclined downward outward so that water or the like does not accumulate in this portion. Further, another lower protruding wall 4b that is substantially in close contact with the inner surface of the upper protruding wall 6a is provided on the upper ring 4.

Next, the operation of the street light having the above configuration will be described. Even if water intrudes from the gap between the lower protruding wall 4a and the upper surface of the lower ring 6, the capillary action can be prevented by the space 10, and no water intrudes into the interior. Further, since the upper surface of the lower ring 6 is inclined downward and outward, water that has entered the space 10 can be discharged to the outside.

As described above, according to this embodiment, since no packing is used, there is no lack of waterproofing and insect repelling performance due to deterioration and peeling of the packing, and stable quality can be maintained. Furthermore, since troubles such as poor packing sticking at the time of assembling the instrument are eliminated and the number of components can be reduced, stable quality and low cost can be achieved.

Further, another lower protruding wall 4b which is substantially in close contact with the inner surface of the upper protruding wall 6a of the lower glove 2
Therefore, even if an insect enters the space portion 10, the contact surface between the upper protruding wall 6 a and another lower protruding wall 4 a can secure a long path for the insect to enter, further improving the insect repelling performance.

Although the upper glove 1 and the lower glove 2 are composed of two members, they may be integrated.

[0016]
