    摘要: A light source and a method for operating the same are disclosed. The light source includes a light emitter and a controller. The light emitter generates light in response to a control signal coupled thereto. The light emitter is characterized by an age related to the amount of light that has been cumulatively generated by the light emitter, the generated light for a given control signal changing with the age. The controller measures the age of the light emitter and generates the control signal based on the desired light intensity and the measured age of the light emitter. In one embodiment, the controller stores an age value for the light emitter, and the controller determines the control signal in response to an input signal specifying a desired light intensity from the light emitter, the controller updating the age value each time the control signal is determined.
