Abstract

An induction RF fluorescent lamp, comprising a lamp envelope and re-entrant cavity filled with a fluorescing gas mixture, a power coupler receiving an alternating voltage and current to generate an alternating magnetic field and thereby inducing an alternating electric field within the lamp envelope, a first metallic structure mounted within the lamp envelope in such a location and orientation to rapidly heat and vaporize mercury to promote rapid luminous development during the turn-on phase of the induction RF fluorescent lamp and a second metallic structure so as to promote electrical breakdown of the fluorescing gas mixture during the turn-on phase of the induction RF fluorescent lamp.

Claims

5-1. The lamp of claim 1 wherein the first metallic structure is substantially flat along a plane.

9. The lamp of claim wherein the first metallic structure is a folded metallic structure constrained along the plane.
