Claims10
A microwave powered electrodeless lamp, comprising,
- microwave energy generating means,
- a microwave cavity,
- an envelope containing substance which emits excimer radiation upon excitation disposed in said microwave cavity, said substance comprising halogen in an amount sufficient to result in a halogen pressure of greater than about 350 torr at operating temperature, and
- means for coupling microwave energy produced by said microwave energy generating means to said cavity to cause said substance to emit excimer radiation.
