Abstract

A low cost reflector compact fluorescent lamp with extended long life electronic ballast is disclosed to operate satisfactorily at an elevated temperature range in insulated ceiling and airtight fixtures such as downlight to replace highly inefficient, unreliable, reflector lamps presently used. The construction of pyramid type top spiral compact fluorescent lamp with special cathode material, filled gas, advanced amalgam, protected multi layered phosphor could operate with a suitable single stage, multi resonant, high power factor, dimming electronic ballast. Technology used to achieve low cost and low profile characteristics of the ballast is single stage, zero energy storage inverter, complementary drive, and high displacement Piezoelectric transformer components.
