Method and apparatus for improved electrodeless lamp screen










Image Number 6 for United States Patent #6465959.

A screen (49) including mesh portions (47 and 48) for a discharge lamp (46) bears a protective coating which inhibits degradation of the screen under lamp operating conditions. The coating does not absorb microwave energy, is transparent or reflective to visible light, and is capable of protecting the screen for at least several thousand hours of operation without substantial oxidation or tarnishing of the screen. The coating remains on the screen at screen temperatures above about 300 degrees C, and the coating does not significantly crack as the screen heats and cools. The coating may include, for example, a solgel deposited single phase or two phase glass.
