More Information
Summary:A light emitting diode lighting apparatus that includes: a power supply for providing a fixed direct current; a light emitting diode head for emitting light; and a controller for adjusting the level of said light output on said head and compensating for efficiency altering effects of said light in said power head, whereby said controller receives signals for optical feedback stabilization, temperature compensation, and detection of short term current changes to adjust said light and efficiency.
