Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a fluorescent lighting fixture having an Edison base and configured to be attachable to an incandescent lamp socket.

(Background Art) Fig. 1 shows a perspective view of the external appearance of a conventional lighting fixture of this type, in which 2 is the fixture body, 5 is a base, 6 is an Edison base, 14 is a heat radiation hole, 16 is a cover, 18
1 is a lamp, 19 is a lamp support, and 20 is a socket. Thus, when forming the Edison base 6 in a lighting fixture as shown in FIG. The cap 5 was fixed to the cylindrical protrusion 3 of the instrument main body 2 by holding the cap 5 between the upper surface of the cylindrical protrusion 3 and fitting the connecting pin 4. Therefore, when connecting to the stabilizer 1 etc. attached to the mounting bracket 12 in the device body 2, a small hole 13 is provided on the circumferential surface of the cylindrical protrusion 3, and the lead wire 9 is inserted through the tip. The other lead wire 9' was soldered 10' to the base 5, and the other lead wire 9' was soldered 10' to the lower end of the direct connection pin 4. Therefore, in such a conventional example, in addition to requiring the insulating plate 11 to hold the base 5, it is also necessary to pass the lead wire 9 through the small hole 13 in order to connect it.
In addition to the problem that the assembly work is complicated, in order to improve the heat radiation effect, it is necessary to provide a heat radiation hole 14 on the upper surface of the device main body 2, and this heat radiation hole 1
4 cannot be installed directly above the ballast 1, so in order to improve the heat dissipation effect, the ballast 1
It was necessary to attach it to the mounting bracket 12 which also served as a heat sink, and there was a problem that overall assembly was poor.

(Purpose of the invention) The present invention provides a fluorescent lighting fixture that reduces the temperature influence of the ballast on the fixture, makes it easy to attach the cap, etc., and facilitates the work of connecting the lead wires, improving the ease of assembly. The purpose is to

(Disclosure of the invention) FIGS. 3 to 5 show an embodiment of the invention, in which a cylindrical protrusion 3 integrally provided at the center of the upper surface of the instrument main body 2
Through holes 7 extending from the lower peripheral surface to the upper surface 15 of the instrument body 2 are formed at several places in the circumferential direction of the cylindrical projection 3, and the base 5 of the Edison base 6 is installed on the peripheral surface of the cylindrical projection 3. Then, the bent pieces 8 at the bottom of the cap 5 are respectively engaged with the upper peripheral edge of the through hole 7, thereby fixing the cap 5 to the cylindrical projection 3. Note that the connecting pin 4 is fixed directly to the center of the upper surface of the cylindrical projection 3. Further, one lead wire 9 from the lighting circuit of the ballast 1 etc. is soldered 10 to the bent piece 8 from the lower surface side of the device main body 2 with a soldering iron 17, as shown in FIG. 9' is soldered 10' to the lower end of the connecting pin 4 as in the conventional case. Further, the stabilizer 1 is directly fixed to the instrument main body 2, and a cover 16 is provided on the lower part of the instrument main body 2.

(Effects of the invention) Since the invention is constructed as described above, there is no need to provide a separate part like a conventional insulating plate to hold the cap, and the lead wire can be connected to the bottom of the device body. Being able to do it from the side has the advantage of simplifying the assembly process and improving productivity.Also, the through holes can also be used as heat radiation holes to lower the temperature inside the device body, so there is no separate heat radiation hole. It has the advantage of not requiring holes, and since the through hole is provided directly above the ballast, it has a good heat dissipation effect and does not require a separate mounting bracket that also serves as a heat sink for attaching the ballast. This has the following advantages.
