[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge lamp ballast used for lighting a discharge lamp such as a fluorescent lamp, and a lighting fixture provided with the ballast.

[0002]

2. Description of the Related Art As discharge lamp stabilizers used for lighting fluorescent lamps, there are known a discharge lamp ballast and a discharge lamp ballast having a quick connection terminal.

As shown in FIG. 4 (A), a discharge lamp ballast 1 of an electric wire draw-out type is formed by extracting a plurality of electric wires 3 to 10 from both ends of a ballast body 2. Each of the electric wires 3 to 10 uses an electric wire formed by insulatingly covering a core wire made of a stranded wire. These wires 3
The two wires 3 and 4 out of 10 to 10 are for power supply, and the remaining wires 5 to 10 are all for wiring to the lamp socket.

As shown in an example of use in FIG. 4B, a pair of lamp sockets 12, 13 or 14, 15 are disposed at both ends in the longitudinal direction of the appliance body 11, respectively. The discharge lamp stabilizer 1 is attached to one side of a power supply hole 16 opened in the center. Lamp socket 1
Straight fluorescent lamps (not shown) are mounted between the lamps 2 and 14 and between the lamp sockets 13 and 15, respectively. The electric wires 3 and 4 of the discharge lamp ballast 1 are connected to the indoor wiring (F cable) drawn into the power supply hole 16, the electric wires 5 and 6 are connected to the lamp socket 13, the electric wires 7 and 8 are connected to the lamp socket 15,
The electric wires 9 and 10 are connected to the lamp socket 14 by soldering or the like. 4B, reference numeral 17 denotes another electric wire, which is used to connect the sockets 12 and 13 to each other.
3 has the same potential.

[0005] According to the discharge lamp ballast 1, each of the lamp sockets 12 to 15 with respect to the fixture main body 11 and the shape of the fixture main body 11 to which the discharge lamp ballast 1 is attached, etc. Lamp socket 13-15
Since the distance to the ballast is different, the ballast manufacturer requires that each wire 3 to 10 previously adjusted to the length corresponding to the distance is drawn out for each type of lighting fixture. It is necessary to prepare a vessel 1. for that reason,
It is necessary to prepare various kinds of discharge lamp stabilizers, and the productivity is low, so that the cost is high.

Instead, long wires 3 to 10 are drawn out and placed in advance, and a surplus generated in actual wiring is shown in FIG.
As shown in (B), if the discharge lamp stabilizer 1 is bound using a band-shaped binding member 18, the discharge lamp ballast 1 can be used in common for various types of lighting equipment. However, in this case, the binding member 18
The cost of the lighting equipment and the time and labor required for bundling the electric wires using the same increase the cost of the lighting equipment.

Further, as shown in FIG. 5A, a discharge lamp ballast 21 having quick connection terminals is formed by mounting a plurality of quick connection terminals 23 to 30 on both sides of a ballast body 22 respectively. I have. The pair of quick connection terminals 23 and 24 are for power supply, and the other quick connection terminals 25 to 30 are all for connection to a lamp socket.

As shown in an example of use of FIG. 5 (B), a pair of lamp sockets 12, 13 or 14, 15 are disposed at both ends in the longitudinal direction of the appliance body 11, respectively. A power supply terminal block 31 and the discharge lamp stabilizer 21 are mounted on both sides of the power supply hole 16 opened in the center in the longitudinal direction. Unillustrated straight tube fluorescent lamps are mounted between the lamp sockets 12 and 14 and between the lamp sockets 13 and 15, respectively. The power supply terminal block 31 has an indoor wiring (F cable) (not shown) that is drawn into the power supply hole 16.
The terminal block 31 and the discharge lamp ballast 21
Are connected via a power supply line 33 which is inserted and connected to these terminals. The quick connection terminals 25 and 26 of the discharge lamp ballast 21 and the lamp socket 13 are
These are connected via electric wires 35 and 36 inserted and connected to these. Similarly, the quick connection terminal 2 of the discharge lamp ballast 21
7, 28 and the lamp socket 15 are connected via electric wires 37, 38 inserted and connected thereto, and the quick connection terminals 29, 30 of the discharge lamp ballast 21 and the lamp socket 1 are connected.
4 is connected via electric wires 39 and 40 inserted and connected to these. FIG. 5B shows another electric wire 17 which is used to connect the sockets 12 and 13 to each other.
Have the same potential.

The discharge lamp ballast 21 can be used in common for various types of lighting equipment, and therefore, the drawbacks of the electric-wire drawer-type discharge lamp ballast 1 and the lighting equipment provided with the same can be solved. However, in a lighting fixture using the ballast 21, the power supply terminal block 31 and the power supply line 33 connecting the power supply terminal block 31 and the discharge lamp ballast 21 are required.

The discharge lamp ballast 1 is connected to each of the electric wires 3 to 10.
Are sorted out from both ends by the same number, and similarly,
Since the discharge lamp ballast 21 has the same number of quick connection terminals 23 to 30 assigned to both ends at the same time, these ballasts 1,
In 21, it is difficult to obtain directionality, and it is easy to attach to the instrument main body 11 in a direction different from an appropriate direction. Accordingly, the indoor wiring may be connected to the electric wire to be connected to the lamp socket, or the power supply line 33 may be erroneously inserted and connected to a quick connection terminal other than the power supply quick connection terminals 23 and 24. When such a situation is reached, an excessive current is applied to the fluorescent lamp and burning occurs.

Further, as shown in FIGS. 4 (B) and 5 (B), any one of the above-described discharge lamp ballasts 1, 21 is used.
A lighting device for a lamp, comprising two lamp sockets 12, 1
3 is the same potential, the lamp socket 1 of the same potential
2 and 13 are connected using an electric wire 17. by the way,
When quick-connecting terminals are provided in each of the lamp sockets 12 to 15 so that the work of connecting electric wires to the lamp sockets can be performed efficiently, the quick-connecting terminals attached to each of the lamp sockets 12 to 15 are adapted to adapt to the circuit. It is necessary to adopt a terminal provided with a plurality of lock pieces for holding a conductor (core wire) of an electric wire. Since the lamp socket, which is a general-purpose component, is used for a lighting fixture for one lamp and a lighting fixture for multiple lamps, one lamp socket having a quick-connecting terminal having a plurality of lock pieces as described above is used. When used for lighting fixtures, will be provided with unused lock pieces,
Over-specification results in high cost.
