Abstract
A beam mode discharge lamp typically has a shortcoming in that emitted light is reduced due to the deposition of cathode material on the phosphor surface. Such deposition can be reduced through the addition of a conductive mesh about the filaments to entrap cathode material and inhibit same from attacking the phosphor material.
