Abstract:

Field balancing may be performed with an irradiation system including a plurality of adjustable radiant-energy emitters. The irradiation system powers the radiant-energy emitters from a power source and radiant energy is emitted from the radiant-energy emitters, where an amount of radiant energy emitted from each emitter is capable of being varied based on power received from the power source. A plurality of radiant-energy sensors detects an amount of radiant energy which includes radiant energy created directly by at least one of the radiant-energy emitters. The amount of radiant energy detected at least two of the radiant-energy sensors is compared, and at least one of the radiant-energy emitters is adjusted by varying the power received from the power source so that the amount of radiant energy detected at each of the radiant-energy sensors tends towards becoming approximately equal. The emitting of radiant energy from each radiant-energy emitter is terminated when a total amount of radiant energy emitted from the plurality of adjustable radiant-energy emitters exceeds a predetermined threshold value, where the threshold value is sufficient to allow the total amount of radiant energy emitted from the plurality of adjustable radiant-energy emitters to sanitize a particular area in which the emitters are located.
