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.

Fast start RF induction lamp with metallic structure

An induction RF fluorescent lamp, comprising a vitreous 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 main mercury amalgam having a vapor pressure at room temperature which is higher than the vapor pressure of the mercury amalgam formed on the flag.

Fast start RF induction lamp

A fast starting induction RF fluorescent lamp capable of changing illumination level through a burst-mode dimming facility, comprising a dimming facility enabling the induction RF fluorescent lamp to dim in response to a control signal, and with structures within the bulb envelope that facilitate rapid luminous development during a turn-on phase.

Fast start induction RF fluorescent lamp with burst-mode dimming

A fast starting induction RF fluorescent lamp that is able to replace an ordinary incandescent light bulb, both in its ability to screw into a standard incandescent light bulb socket and to have the general look of the ordinary incandescent light bulb, but with all of the advantages of an induction lamp, as described herein. The present disclosure describes structures for an induction RF fluorescent lamp that includes a bulbous portion, an electronics portion, and a screw base, creating an external look that is similar to the profile of an ordinary incandescent light bulb, and with structures within the bulbous portion that facilitate rapid luminous development during the turn-on phase of the induction fluorescent lamp.

Fast start induction RF fluorescent light bulb

A fast starting induction RF fluorescent lamp comprising a power coupler with conductive material in contact with the power coupler to reduce extraneous electromagnetic radiation emanating from the power coupler, and with structures within the bulb envelope that facilitate rapid luminous development during a turn-on phase.

Fast start induction RF fluorescent lamp with reduced electromagnetic interference

A fast starting dimmable induction RF fluorescent lamp comprising a dimming facility enabling the induction RF fluorescent lamp to dim in response to a signal from an external dimming device, and with structures within the bulb envelope that facilitate rapid luminous development during a turn-on phase.

Fast start dimmable induction RF fluorescent light bulb

A high intensity discharge lamp () has an envelope () having a base end (), a middle portion () and domed end () arrayed along an envelope longitudinal axis (). Two spaced apart electrical lead-ins () are sealed in the base end () and extend into the envelope (). A substantially U-shaped frame () is within the envelope () and the U-shaped frame comprises glass tubingA light source () has an arc discharge capsule () positioned within the frame () and a containment vessel () is spaced from and surrounds the arc discharge capsuleThe containment vessel () comprises a transparent structure () attached to the frame () and formed to provide multiple, independent, localized fractures capable of absorbing the given kinetic energy possessed by the shards.
