ABSTRACT:
A quick start ultraviolet emission unit with an elongated, electrode-type, mercury-filled, arc lamp having spaced end electrodes connected to an electrical power supply that connects to an alternating current power source and to each end electrode of the arc lamp for powering the lamp with an alternating current having a sinusoidal cycle, the unit includes a pulse generating, circuit means connected to said power supply for generating a high current, high voltage, electrical pulse added to the alternating current to the lamp during start-up and restart and a trigger circuit connected to the pulse generating circuit for triggering generated high current, high voltage electrical pulses at the peak potential in the sinusoidal cycle of the alternating current form the power supply.
