Compact fluorescent lamp with extended legs for providing a cold spot

摘要

A low pressure discharge lamp, particularly a compact fluorescent lamp, achieves substantially the same base-down lumen output as base-up lumen output. The lamp does so in a bent and bridged configuration, preferably in the shape of a plurality of vertically oriented bent tubes horizontally bridged together, where at least one of the tubes has at least one extended leg that defines a cold chamber within or adjacent the base.
