More Information
Summary:An electrodeless lamp includes a stationary bulb containing a fill for producing a discharge, the sill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium which may be introduced in the unexcited fill as, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field such as, for example, a circular polarized electric field. Several electrodeless lamp structures are disclosed for producing a circular polarized electric field.
