ABSTRACT:
An electronic device includes a light source, which generates light in response to a signal, and a controller. Because the luminosity of the light source decays over time, the controller generates a utilization value based on a cumulative time that the light source is emitting light, and regulates the signal that is provided to the light source in response to the utilization value to at least partially compensate for decay in the luminosity of the light source.
