From LEDs Magazine – Control circuit for dimming and color mixing

Control circuit for dimming and color mixing? Boca Flasher has been awarded US patent 7,088,059 entitled "Modulated Control Circuit and Method for Current-Limited Dimming and Color Mixing of Display and Illumination Systems." The patent describes a control circuit for a lighting system that allows analog control over a range of illumination intensities in which the source intensity varies in proportion to the voltage level of the control signal. The circuit provides for improved dimming and color mixing capability by allowing pulse width or frequency modulation control in addition to analog control over a second range of illumination intensities.
