ABSTRACT:
A compact fluorescent lamp with a screw-in plug to fit conventional screw sockets which operates at 20-30 watts and provides the lumen output of a 75-100 watt lamp. The lamp is essentially a hollow cylinder with a glass envelope for the two outer walls. The space between the two outer walls is partitioned to constrain the arc discharge to follow a designated path around the inner surface of the lamp. Efficiency is promoted by novel ballast design. The screw-in fluorescent lamp contains a coil in the center of the lamp which creates a diverging magnetic field which causes the arc discharge to spread and may also serve the dual purpose of limiting arc current. Arc spreading coils of several designs are disclosed to provide oriented diverging magnetic fields, rotating diverging magnetic fields and magnetic fields shaped to the lamp envelope with which they are employed.
