摘要： A plasma lamp is described with resonant frequency tuning capability and associated methods for tuning. One tuning method allows plasma lamp manufacturer to set the frequency of lamps to several discrete predetermined values. For example, most lamps that are near the center of a frequency distribution can be tuned to a nominal value such as 918.7 MHz. Other frequencies can also be tuned to increase manufacturing yield and improve lamp performance.

摘要： Systems and methods for an electrodeless plasma lamp as described. A drive probe is coupled to the lamp body to provide the primary power for ignition and steady state operation of the lamp. Feedback is used to adjust frequency in response to changing conditions of the lamp during startup. A phase shifter is 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. The phase shift may then continue to be adjusted as the plasma heats up and the impedance continues to change. The bias conditions of an amplifier may be changed to change the operating class of the amplifier for different modes of the lamp.

摘要： An electrodeless plasma lamp having a bulb containing a fill that forms a light-emitting plasma is described. The lamp includes a power amplifier to provide radio frequency power to the fill at a frequency in the range of about 50 MHz to 10 GHz and the power amplifier is configured to operate in at least two classes of operation. Control electronics of the lamp is configured to change the class of operation of the power amplifier during operation of the plasma lamp. For example, the power amplifier may be configured to operate as a class A/B amplifier during at least a first mode of operation and a class C amplifier during at least a second mode of operation.
