China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The High-pressure sodium lamp electronic ballasts: relates to a discharge lamp ignition control circuit devices, in particular, the case for high-pressure sodium lamp ignition, oscillating electronic ballasts control a full bridge. The utility model the four switching power transistors to form a full-bridge oscillator, amorphous core as electric reactor, and the control circuit board. Implementation of the utility model can be obtained as follows positive effect; saving of up to 65% or more, and a 150W sodium lamp power consumption dropped from 4A to 1,3 A, power factor of 0.98 or more.
