ABSTRACT:
An RF source is periodically pulsed for exciting an electrodeless light bulb in an on-off mode so as to intermittently drive the bulb to a high peak power operating point where light generation efficiency is relatively high, while maintaining a relatively low average power input. Pulse rate and duration are optimized to minimize light flicker while maximizing light emission efficiency.
