APPARATUS AND METHOD FOR LED RUNNING LIGHT CONTROL AND STATUS
摘要
A light emitting diode (LED) running light comprises a current sink and a plurality of series coupled LED block cells; each of the plurality of LED block cells comprising a LED and a bypass circuit to the current sink, wherein each series coupled LED sequentially turns on (lights) when a voltage source increases by additive voltage increments of at least the turn-on voltage of each LED in the series coupled string until all LEDs are on (lit). The current sink maintains a desired current value through the LEDs and may also be used to provide waveforms for diagnostic and timing purposes
