Abstract
A miniaturized vapor discharge lamp assembly that includes a light transmissive bulb containing a buffer gas and a vaporizable light radiating substance such as rubidium. Lamp excitation is provided by the use of a capacitor in the lamp assembly in conjunction with an RF oscillator. The capacitor establishes a substantially longitudinal electric field which ionizes the rubidium vapor to cause emission of light. The need for an RF excitation coil is eliminated.
