Abstract
An apparatus includes a light source operable to produce light having a wavelength, an optical component disposed over the light source so as to intersect a path of light produced by the light source, and at least one electrically conductive trace on a surface of the optical component. A drive controller is operable to regulate optical output power of the light source. The at least one electrically conductive trace is coupled electrically to the drive controller, which is operable to monitor an electrical characteristic of the at least one electrically conductive trace, and to reduce the optical output power of the light source if a value of the electrical characteristic is indicative of a possible eye-safety hazard.
