ABSTRACT:
An electrodeless high intensity discharge lamp includes an electrodeless lamp capsule having an enclosed volume containing a mixture of starting gas and chemical dopant material excitable by high frequency power to a state of luminous emission, an applicator for coupling high frequency power to the lamp capsule, a gas nozzle directed toward the lamp capsule and a gas controller coupled to the gas nozzle. The gas controller receives gas from a gas source and supplies a gas puff of limited duration to the lamp capsule through the gas nozzle in response to termination of the state of luminous emission. The lamp capsule is rapidly cooled by the gas puff to a temperature required for restart.
