容易になり、製品寸法が安定することになる。As shown in FIG. 1, an instrument shell 1 made of a synthetic resin molded product having an opening on the lower surface, and a translucent cover 2 made of a synthetic resin product that covers the opening surface of the instrument body 1 in a closed manner. 3 is formed. There is a lamp socket 7 on the fixture body 1.
Is mounted on the socket base 8. The socket base 8 holds the lamp 4 having the base only at one end of the tubular bulb. The lamp 4 is a fluorescent lamp and has a substantially U-shaped discharge path in which the insides of a pair of straight tubes communicate with each other at one end. A plate-shaped reflector 9 is arranged above the lamp 4, and a holding spring 10 for holding the lamp 4 is arranged at a portion of the reflector 9 corresponding to the tip of the lamp 4. The translucent cover 2 is hinged to the main body 1 of the lamp via a hinge portion 11 at one end on the tip end side of the lamp 4, and the other end of the translucent cover 2 is translucent. Cover 2
A fixing screw 12 is threadedly engaged with the instrument body 1 through. Therefore, if the fixing screw 12 is loosened, the translucent cover 2 can be opened with respect to the instrument body 1. As shown in FIG. 3, a surrounding wall 13 is provided on the periphery of the outer surface of the side wall of the appliance body 1 at one end of the lamp 4 on the base side so as to surround the entire circumference. In addition, one end of the cylindrical hole 14 opens in a region surrounded by the surrounding wall 13. A distal end portion of a metal arm 5 for attaching a device, which has a substantially U-shaped cross section and is bent in a substantially L-shape, is inserted into the cylindrical hole 14. A metal reinforcing plate 15 is provided on the opposite side of the arm 5 with the peripheral wall of the cylindrical hole 14 interposed therebetween.
The instrument body 1, the arm 5 and the reinforcing plate 15 are fixed to each other by the screw 6 as a fixing tool which is screwed into the arm 5 from the inside of the instrument body 1 through the reinforcing plate 15. Arm 5 and reinforcing plate
An opening window 16 is formed on the peripheral wall of the cylindrical hole 14 between the opening 15 and the hole 15. In addition, as shown in FIG.
A convex portion 16a to be inserted into the opening window 16 is formed, and when the reinforcing plate 15 and the arm 5 are coupled by the screw 6, the opening window 16a is formed.
The tip surface of the convex portion 15a is closely attached to the arm 5 through 16. As described above, insert one end of the arm 5 into the cylindrical hole 14,
Since the instrument body 1 and the arm 5 are connected inside the cylindrical hole 14, the instrument body 1 and the arm 5 are installed even when installed outdoors.
Rainwater, etc. does not enter the joints with and no waterproof structure is required. Further, since the joint portion of the arm 5 with the fixture body 1 is hidden inside the fixture body 1, the exposed portion of the arm 5 is reduced, and a lighting fixture having a beautiful appearance can be provided. A ballast 17 is installed in the instrument body 1 as a component for lighting the lamp 4. The ballast 17 is fixed to a metal component mounting plate 18 with a screw 19, and a part of the component mounting plate 18 is in close contact with the reinforcing plate 15 so that the arm 5 is fixed with the screw 20.
(See FIG. 2). According to this configuration,
The heat generated in the ballast 17 is transmitted to the arm 5 via the component mounting plate 18 and the reinforcing plate 15, and passes through the arm 5 to the instrument main body 1
It is released to the outside of. As described above, by taking out the heat generated from the ballast 17 to the outside of the instrument body 1 through the arm 5, it is possible to suppress the temperature rise inside the instrument body 1 and to reduce the luminous efficiency of the lamp 4. Can be prevented. By the way, since the tubular hole 14 is formed in the instrument body 1, the instrument body 1 is molded as shown in FIG.
21 corresponding to the inside of the mold and the mold 22 for forming the cylindrical hole 14
It is necessary to use and. Here, since the convex portion 21a forming the opening window 16 is formed in the mold 21, the cylindrical hole 14
The mold (side core) 22 inserted to form the mold is supported by the convex portion 21a, and the position of the mold 22 is stabilized. As a result, it becomes easy to control the wall thickness of the peripheral wall of the cylindrical hole 14, and the product size becomes stable.
