ABSTRACT:
An electrodeless lamp system and method for providing light output having a controlled spectral distribution. A lamp having a fill which is not fully vaporized at the lamp operating temperature and which emits in a characteristic region of the spectrum is used. A function generator generates a function signal, and the magnitude of the lamp output in the characteristic region or the ratio of such magnitude and a magnitude in a different characteristic region is compared with the function signal. The difference signal is used to control the amount of cooling gas which is incident on the lamp bulb to control the spectral distribution of the radiation which is emitted by the lamp.
