Induction RF fluorescent lamp with load control for external dimming device

摘要

An induction RF fluorescent lamp comprising a dimming device load control facility enabling the induction RF fluorescent lamp to provide for electrical loads required for the proper operation of an external control dimming device, the dimming device load control facility controlling a switched electrical load switched in and out of connectivity within the electronic ballast to provide a load for the external dimming device.

主权项

1. An induction RF fluorescent lamp, comprising:
a lamp envelope filled with a ionizable gas mixture at less than typical atmospheric pressure; 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 device load control facility enabling the induction RF fluorescent lamp to provide for electrical loads required for the proper operation of an external control dimming device, the dimming device load control facility controlling a switched electrical load switched in and out of connectivity with the electronic ballast to provide a load for the external dimming device; wherein the switched electrical load is switched out of the circuit during on-time intervals of the external dimming device and switched into the circuit during off-time intervals of the external dimming device.
