Abstract
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.
Claims17
A dimmable induction RF fluorescent lamp, comprising:
- a lamp envelope filled with a gas mixture at less than typical atmospheric pressure, wherein the lamp envelope comprises a first metallic structure for collecting mercury and a second metallic structure to aid in the electrical breakdown of the working gas mixture, the first and second metallic structures promoting the rapid development of luminosity of the induction RF fluorescent light bulb during a turn-on phase;
- a power coupler comprising at least one winding of an electrical conductor;
- an electronic ballast providing appropriate voltage and current to the power coupler;
- and
- a dimming facility enabling the induction RF fluorescent lamp to be dimmable from an external control dimming device.
