Abstract
Systems for providing optical energy comprise an LED, a detector of optical energy, such as a photodiode, that measures the intensity of optical energy emitted by the light-emitting diode, and a controller. The controller adjusts the intensity of the optical energy emitted by the LED based on the intensity measurement provide by the photodiode, to maintain the intensity of the emitted optical energy at a desired level.
