A current limiting device includes a constant current source circuit
constructed and arranged to be connected to a direct current input
voltage source and to regulate electrical current and a resonance source
circuit receiving current from the constant current source circuit. The
resonance source circuit is constructed and arranged to be electrically
connected with an electro-luminescent (EL) lamp so that the EL lamp
receives alternating current. The constant current source circuit and the
resonance source circuit are constructed and arranged such that when
current flows from the constant current source circuit to the resonance
source circuit and to the EL lamp, a maximum peak current received by a
user contacting an output of the device or contacting the EL lamp is less
than about 0.7 mA.
