Abstract
A device for regulating the intensity of light emitted by a lamp includes a variable inductor configured to surround a portion of the lamp and electrical circuitry arranged to connect electrically the variable inductor to the lamp in a manner such that a variation in the inductance of the variable inductor will cause a corresponding variation in the intensity of light emitted by the lamp while the lamp is electrically connected to the variable inductor.
