A built-in ballast stabilizer is provided to prevent an electric leakage or an electric shock by being installed inside a streetlight. A multi-ballast(10) has a stabilizing function unit composed of a transformer, a condenser, and a high voltage generator and a PCB with a flickering function and an electric leakage breaking function at a lower part of the stabilizing function unit. A slot unit(20) is formed long on a rear surface of the multi-ballast and has slot holes(21) at both sides. An upper coupling unit(30) is formed at a rear upper part of the multi-ballast and coupled with the slot unit by a bolt. A lower coupling unit(40) is formed at a rear lower part of the multi-ballast and coupled with the slot unit by a bolt. A terminal unit(50) is coupled on a bottom of the multi-ballast by a bolt to be connected to various devices of the multi-ballast and an external wire. |
