Abstract
A mercury vapor lamp having a light transmissive envelope defining an arcuate capillary plasma cavity. A mounting base secured to one end of the envelope has a configuration which is geometrically unique with respect to the position and spatial orientation of the plasma cavity. A mounting block and clamping arrangement have a configuration complementary to that of the lamp base so as to receive and releasably secure the lamp base and, therefore, the plasma cavity in a fixed predetermined position and orientation relative to its operating environment. The lamp is energized by means of an electrical potentional applied to electrodes in the plasma cavity or by reactance coupling an r-f power source to the cavity.
