Abstract: A power saver for discharge lamps, in which supply of electricity is not stopped instantaneously even though applied voltage is converted into lower voltage after lighting the discharge lamp, is disclosed. The power saver for discharge lamps includes a first coil, a second coil having a winding direction opposed to a winding direction of the first coil and located in an opposite direction of the first coil, an insulator located at a gap part where the first coil and the second coil are opposed, at least one or more taps arranged along a longitudinal direction of the second coil, at least one or more switches selectively connected to one of the taps, at least one or more first timers connected to the switches respectively, an electric relay mounted in a loop circuit including both end parts of the second coil, and a second timer connected to the electric relay.
