Abstract
A fluorescent lamp assembly is comprised of a lamp and a ballast therefor. The lamp includes an internal, solid wire starting aid connected to third lead-in wire sealed in an end of the lamp. A resistive ballast serially couples the lamp electrodes to a lamp starting means such as a glow-bottle. The starting aid is capacitively coupled to a lead-in wire of its adjacent electrode.
Claims3
A fluorescent lamp assembly comprising:
- a fluorescent lamp having a tubular glass body with electrodes at each end thereof, each electrode being supported by a pair of lead-in wires sealed in glass sealing means;
- a layer of phosphor on the interior surface of said body and an arc generating and sustaining medium therein;
- one of said ends being provided with a third lead-in wire adjacent to one of said electrodes;
- a wire starting aid connected to said third lead-in wire and extending the length of said body to a position adjacent said other electrode;
- a resistive ballast for said lamp serially coupling said electrodes and a lamp starting means;
- and means capacitively coupling said third lead-in wire to one of the lead-in wires of its adjacent electrode.
