Abstract
In an example, a method of operating an ultraviolet (UV) light source includes providing a supply power to the UV light source, and activating, using the supply power, the UV light source to emit UV light during a series of activation cycles. The method also includes, during at least one activation cycle in the series, sensing the UV light emitted by the UV light source to measure an optical parameter of the UV light. The optical parameter is related to an antimicrobial efficacy of the UV light. The method further includes adjusting, based on the measured optical parameter, an electrical parameter of the supply power to maintain a target antimicrobial efficacy of the UV light over the series of activation cycles.
