    摘要: An electrodeless plasma lamp and a method of generating light are described. The lamp may comprise a lamp body including a dielectric material having a relative permittivity greater than 2. A lamp drive circuit is coupled to the lamp body and configured to provide radio frequency (RF) power to the lamp body. A bulb containing a fill is positioned proximate the lamp body. The fill forms a plasma when the RF power is coupled to the fill from the lamp body. A lamp drive circuit including modulation control circuit is provided to control modulation of a frequency of the RF power across a frequency band. The circuit may be configured to provide RF power across a frequency band around a resonant frequency for the lamp body to reduce peak amplitude and electro-magnetic interference while maintaining average power to the plasma.

    摘要: In one example embodiment, a drive probe is coupled to the lamp body to provide the primary power for ignition and steady state operation of the lamp. Feedback may be used to adjust frequency in response to changing conditions of the lamp during startup. A phase shifter may be used to adjust the phase of the power between ignition and steady state operation. A sensor may detect a lamp operating condition that automatically triggers a shift in phase after the fill in the bulb is vaporized. In another example embodiment, a method for sequentially optimizing the drive power and phase shift applied to the lamp is disclosed that may reliably regulate the lamp current consumption to desired startup and operational levels despite variations in lamp environmental conditions.
