BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater lighting fixture.

[0002]

2. Description of the Related Art FIG. 9 shows a conventional underwater lighting apparatus (first conventional example).
The instrument main body 1, the front glass 2, the main body frame 3, the reflecting mirror 4, and the socket 5 are configured.

The instrument body 1 has a bottomed tubular shape, and the front side, which is one side thereof, has an opening 1a, a flange portion 1b is provided at the end of the opening 1a, and a side wall 1c is provided. A power line introducing portion 1d having a waterproof function for introducing the power line 6 is provided inside. And
On the side opposite to the opening 1a, a socket 5 for mounting the lamp 7 is fixed via a socket base 5a.

The front glass 2 is a circular plate-shaped glass and is arranged on the side of the opening 1a of the instrument main body 1.
It has a size that covers a, is placed on the flange portion 1b through the waterproof packing 8, and is attached by the screw 9 so as to be sandwiched between the flange portion 1b by the main body frame 3 described later, and the instrument main body. The waterproofness of the space formed with the 1 is secured. Further, the main body frame 3 has a substantially plate-like shape having the same diameter as that of the substantially flange portion 1b, and has a central portion opened so as to expose the front glass 2.

The reflecting mirror 4 has a substantially bowl-like shape and is provided with an insertion hole 4a at the bottom thereof through which the lamp 7 mounted on the socket base 5a is inserted.
Is fixed to the instrument body 1 on the front side of the socket base 5a so as to maintain a predetermined distance between them. This predetermined distance is
Although it is possible to reduce the number as much as possible, a certain size is required in consideration of the dimensional variation of parts.

FIG. 10 and FIG. 11 show another conventional underwater illuminator (second conventional example). The difference from the first conventional example is that the front glass, the reflecting mirror, and the lamp. Shield lamp for underwater use 10
The connection portion 10a of the power supply line 6 is provided on the back side of the shield lamp 10, and the shield lamp 10 is waterproofly attached to the opening 1a on the front side of the instrument body 1 through the waterproof packing 8. Is configured substantially the same as the first conventional example.

Such an underwater luminaire is generally called a buried floor type, which is attached by providing a mounting plate (not shown) on the flange portion depending on the mounting method.
There is a so-called direct mounting type in which an instrument body is provided with an arm having a substantially U-shape and is attached by the arm.
