Abstract
A lamp having a cold cathode field emission plate; an anode plate having a transparent substrate having a first side and a second side; a transparent conductive coating formed on the first side of the transparent substrate; a phosphor layer formed on the transparent conductive coating, and a filter formed on the second side of the transparent substrate; and a voltage source connected across the cathode and the anode plate.
