  • LED string driver with light intensity responsive to input voltage
    Patent number: 8174212
    Abstract: A driving arrangement for a plurality of light emitting diodes (LEDs), the driving arrangement constituted of: a plurality of serially connected first LEDs coupled to a source voltage; a plurality of first electronically controlled switches, each associated with a particular one of the plurality of serially connected first LEDs and arranged to provide, when closed, a bypass current path for the associated first LED; and a control circuitry coupled to a control terminal of each of the plurality of first electronically controlled switches, the control circuitry operative to close a number of the plurality of first electronic switches, the number responsive to a voltage level of the source voltage.
