Abstract: A light source includes a first LED in communication with a first DAC; a second LED in communication with a second DAC; a third LED in communication with a third DAC; a color sensor capable of sensing light in the visible light spectrum; and one or more processors configured for: receiving color intensity values from the color sensor, determining whether the color intensity values are balanced to achieve white light, adjusting the current to the second DAC and third DAC until the color intensity levels are balanced to achieve white light at a combined intensity level, setting a new red LED current value, a new green LED current value, and a new blue LED current value to adjust the combined intensity level toward a target intensity level, and repeating the setting step until the target intensity level is achieved.

Abstract: An endoscopic system having a light source that can operate in two modes is provided. The first mode provides a white light to an endoscope to transmit the light to a surgical site or other object, the reflection of which can be received by the endoscope and for the process. The second mode of the light source provides infrared excitation light and light in the blue and green wavelength spectra to an endoscope to transmit the light to an object such as a surgical site. The blue and green reflected light, as well as light from excitation markers, which is an infrared light at a different wavelength than the excitation infrared light, is received by the endoscope and further processed.
