Description

[Detailed description of the invention] The present invention relates to a compact fluorescent light fixture that is mainly configured to be compatible with conventional incandescent light bulbs, and aims to reduce its size by devising the internal parts arrangement and connection relays. It is.

Conventionally, so-called fluorescent lamps with bulb bases that have such compatibility have not been commercialized very often,
There are two types of fluorescent lamps: one is a type in which the fluorescent lamp can be replaced, and the other is a so-called disposable type in which the fluorescent lamp cannot be replaced. The former method requires a socket to replace the fluorescent lamp, so it is difficult to miniaturize the device, and the connection portion must have sufficient insulation. The latter method is advantageous for miniaturization since there is no need to replace the fluorescent lamp, but its advantages cannot be fully utilized unless the arrangement of parts and connection relays are carefully considered.

The present invention relates to a fluorescent lamp device of the latter type, which is miniaturized by devising the arrangement of parts and connection relays, and one embodiment thereof will be described below with reference to the drawings.

1 is an overall side view, FIG. 2 is a bottom view of the chassis, FIG. 3 is a perspective view of the main parts when assembled, and FIG. 4 is a perspective view of the main parts when disassembled.

1 is a chassis, and an electrical connector 2 is provided on the upper surface. The electric connector 2 may be a base similar to an incandescent light bulb or a hook-and-seal type. A stabilizer 3 is provided at the center of the lower surface of the chassis 1. Then, chassis 1 surrounds ballast 3.
A C-shaped fluorescent lamp 4 is provided on the lower surface of the lamp. This fluorescent lamp 4 differs from the conventional ring-shaped lamp having a cap with a pin for insertion into a socket, and has lead wires 5, 6, 7, and 8 extending from both ends.
9 and 10 are filaments. Further, reference numeral 11 is a support spring that supports the fluorescent lamp 4 from the chassis 1. Reference numeral 12 denotes an insulating stand, which is provided using the space between both ends of the fluorescent lamp 4. This arrangement is possible because the fluorescent lamp 4 is C-shaped. A glow lamp 13 has lead wires 14 and 15 arranged in the same manner as the fluorescent lamp 4, and does not have a cap for screwing into a socket. A glove 16 is attached to cover the bottom surface of the chassis 1. 17 is a noise prevention capacitor. On the insulating table 12, there are square metal pins 18 at its four corners.
19, 20, 21 are provided, and lead wires 5 to 8,
14, 15, lead wire 22 of capacitor 17,
23. A lighting circuit is formed by wrapping the lead wire 24 from the ballast 3 and the lead wire 25 from the electrical connector 2 around each of the metal pins 18 to 21 and relaying the wires as shown. In addition, insulation stand 1
2, in order to provide the glow lamp 13, a mounting portion consisting of ribs 26, 27, 28, an L-shaped holding piece 29, and positioning pins 30, 31 are formed. Incidentally, since the glow lamp 13 only needs to be provided on the insulating stand 12, it is of course possible to fix it with adhesive tape or adhesive. Furthermore, instead of wrapping each lead wire to the metal pins 18 to 21 described above, it may be soldered. Alternatively, each lead wire may be connected directly without the metal pins 18 to 21 and held on the insulating stand 12. Good too. In the latter case, there is a method of inserting and holding the connection portion into a hole formed on the insulating base 12 when the metal pins 18 to 21 are removed. Note that 32 is a lead wire connected from the other pole of the electrical connector 2 to the ballast 3.

In the present invention configured as described above, the insulating stand equipped with the glow lamp is placed using the space between both ends of the C-shaped fluorescent lamp, which greatly improves the efficiency of space utilization. In addition to contributing to the miniaturization of fluorescent light fixtures, the insulating stand connects and relays the lead wires of each electrical component of the ballast, fluorescent light, glow lamp, and electrical connector, so the connection parts can be concentrated. The wire connection process is easy to perform and has the effect of improving productivity. And, of course, fluorescent lamps.
Unlike conventional glow lamps, the glow lamp is of a lead wire arrangement type that does not require a socket, so it goes without saying that it contributes to miniaturization.
