  • Light emitting diode driver circuit
    Patent number: 8723425
    Abstract: The present teachings provide a device and method of regulating current flow across an array of emitting diodes (LEDs) for the purpose of illumination. The device has a power supply (vext) connected to an LED array. The LED array is connected to a current foldback element, a current limitation element, a current sensing element, and a current switch. Current through the array of light emitting diodes achieves an upper current level, the current sensing element signals activation of the current limitation element, said current limitation element maintains current through the array of light emitting diodes at approximately the upper control limit.
