METAL VAPOR LAMP HAVING LOW STARTING VOLTAGE

摘要

A metal vapor lamp and starting apparatus includes a metal vapor lamp having an outer envelope containing a gas filled arc tube having a pair of spaced electrodes with a starting aid surrounding the arc tube intermediate the electrodes, a non-linear dielectric element shunting the spaced electrodes and a ballast means and an electrical conductor coupling the spaced electrodes to a base member connected to a low voltage source whereby starting of the metal vapor lamp from a low voltage source is effected.
