続している。The discharge lamp ballast 12 has a choke coil 14, and a current fuse 15 is interposed between one end of the choke coil 14 and the mold [11], and a current fuse 15 is interposed between the choke coil 14 and the other end of the choke coil 14. A current fuse of 1G is interposed between the discharge lamp 13 and one end of the discharge lamp 13, and a power factor improving capacitor 17 and a resistor 18 are connected in parallel to the power source 11 on the power source side.
前記放電灯１３の他端は外部配ａ１９によって電源１１

．． 16, the choke coil 14 can be protected against overcurrent even if the choke coil 14 and the discharge lamp 13 are connected in series with the electric current fQ11.
When the discharge lamp ballast 12 is housed in a metal case (not shown) or the like, the common line 20 is only one on the power supply side, and no wire is wired from the power supply side to the discharge lamp side, as shown in Figure 1. A discharge lamp lighting circuit can be configured. Therefore, the common line from the power supply side in the ballast to the discharge lamp side can be removed, reducing costs, and the number of wires connected to the discharge lamp ballast 12 is three in total: two on the power supply side and one on the discharge lamp side. can be reduced to
