  • Light emitting diode driving apparatus with high power and wide dimming range
    Patent number: 7342577
    Abstract: Apparatus are provided for driving an LED light source and controlling a light output of the light source over a wide luminance range in response to a luminance input. The apparatus includes: a voltage source having an output configured to couple with the light source, a first input configured to receive the luminance input, and a second input; a photodetector unit configured to logarithmically compress the luminance range and determine a voltage based on a luminance of the light source in the compressed range; a comparator having an input coupled to the photodetector unit and having an output; and, a signal converter having an input coupled to the output of the comparator and having an output coupled to the second input of the voltage source. The voltage source is configured to generate an output signal at the output of the voltage source. The output signal has a frequency and a pulse width based on the luminance input.
