<p>A high intensity discharge lamp constructed with a tubular envelope composed of single crystal sapphire (100) in which a continuous non-flash arc is created across multiple electrodes (207, 209) to generate a radiation emitting plasma. The lamp may operate at higher temperatures and pressures than conventional high intensity discharge lamps to produce greater luminance at any given power output. A wide range of gases and additives may be chosen. The lamp is a small powerful light source, has a longer effective life, and maintains a selected color temperature over the live of the lamp. The lamp may be operated without electrodes utilizing microwave or radio frequency radiation as a power source.</p> |
