LIMITED CURRENT CIRCUIT FOR ELECTRO-LUMINESCENT LAMP INVERTER

摘要

A current limiting device includes a constant current source circuit (12) constructed and arranged to be connected to a direct current input voltage source and to regulate electrical current and a resonance source circuit (14) 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 (28) 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.
