Abstract:
1. A low pressure fluorescent lamp comprising: a discharge tube extending from a first end to a second end, wherein the discharge tube defines an inner surface and an outer surface; a phosphor coating on the inner surface of the discharge tube; a resistive transparent coating on the outer surface of the discharge tube, wherein the resistive transparent coating has a resistivity of about 10 ohms to about 10,000 ohms; and a pair of electric terminals positioned on the discharge tube such that a first terminal is on the first end and a second terminal is on the second end; the lamp further comprising a lamp driver electrically connected to a discharge driver and a heating driver, wherein the discharge driver is electrically connected to the first electrode and the heating driver is electrically connected to the resistive transparent coating on the first end of the discharge tube.
