Abstract

A high-power light system includes a lamp for producing light within a designated wavelength range, a chiller for maintaining the lamp below a defined temperature threshold, and a control module for regulating operation of both the lamp and the chiller. The lamp includes a plurality of light emitting diodes (LEDs) arranged into independently-operable modules. In use, the control module selectively overdrives the LEDs to yield high-power light within the designated wavelength range. To prevent overheating within the lamp, the control module restricts the lamp to a pulse-based operational cycle, whereby each period of LED activation is of limited duration and is immediately followed by a period of deactivation at least three times as long in duration as the period of activation. Additionally, one or more temperature sensors are disposed within the lamp and enable the control module to temporarily suspend LED activation when measured temperature levels exceed the defined threshold.
