Fast start RF induction lamp with metallic structure
First Claim
1. An induction RF fluorescent lamp, comprising:
- a bulbous vitreous portion of the induction RF fluorescent lamp comprising a lamp envelope filled with a working gas mixture;
a power coupler comprising at least one winding of an electrical conductor for receiving an alternating voltage and current to generate an alternating magnetic field and thereby induce an alternating electric field within the lamp envelope;
an electronic ballast providing appropriate voltage and current to the power coupler; and
a first metallic structure attached to a cavity wall and extending outwardly radially therefrom and within the bulbous vitreous portion outside a re-entrant cavity comprising mercury, the first metallic structure mounted within the lamp envelope and adapted to absorb power from the electric field and induce discharge during a turn-on phase of the induction RF fluorescent lamp in a manner sufficient to rapidly heat and vaporize the mercury and promote rapid luminous development during the turn-on phase of the induction RF fluorescent lamp.

Abstract
An induction RF fluorescent lamp having a bulbous vitreous portion of the induction RF fluorescent light bulb including a lamp envelope filled with a working gas mixture. The lamp includes a power coupler and an electronic ballast. A first metallic structure is attached to a cavity wall and extends outwardly radially therefrom and within the lamp envelope outside a re-entrant cavity including mercury. The first metallic structure is mounted within the lamp envelope and adapted to absorb power from the electric field and induce discharge during a turn-on phase of the induction RF fluorescent lamp in a manner sufficient to rapidly heat and vaporize the mercury and promote rapid luminous development during the turn-on phase of the induction RF fluorescent lamp.
