Abstract

A system, method, and computer program product for optimizing the cooling of a UV bulb during a UV irradiation process is described. A power level in which to operate the UV bulb is received. In addition, a particular type of UV bulb being used in the UV irradiation process is received. Thereafter, at least one optimal UV cooling parameter that corresponds to the power level and the type of UV bulb is retrieved from a UV source parameters database. At least one control signal is then sent to a cooling device that is based on the retrieved optimal UV cooling parameter, and the control signal instructs the cooling device to cool the particular type of UV bulb according to the retrieved optimal UV cooling parameter during the UV irradiation process.
