    摘要: A discharge lamp comprises an HPS discharge device within an outer envelope filled with inert gas. A normally nonconductive spark gap device within the outer envelope is connected across conductors used to apply a voltage to the HPS discharge device. The spark gap breaks down when the applied voltage exceeds a certain value to prevent breakdown through the inert gas within the outer envelope.
