Abstract: A luminaire includes a phosphor that emits non-coherent, visible light when excited, a laser diode that emits a laser beam to excite the phosphor, and a driver that outputs electrical DC power at or above the voltage level necessary to drive the laser diode. The current output from the driver to the laser diode is modulated with a code, preferably a random generated code. A visible light sensor detects light emitted from the phosphor and provides a feedback signal, which contains the code under normal operation. If the proper code is not detected in the feedback signal, power output to the laser diode is immediately ceased or reduced to a level safe for the human eye.
