ABSTRACT:
A variable intensity LED illumination system is configured to provide a change in luminance versus input voltage that corresponds to a desired transfer function, such as the dimming characteristics of an incandescent lamp, which more closely resembles the response of the human eye. The system also advantageously provides overvoltage protection, increased brightness, energy efficiency, and significantly better longevity and ruggedness, compared to incandescent lamps.
