Claim Text:
1. An integrated LED lamp, comprising: a first power pin coupled to a first power voltage; a second power pin coupled to a second power voltage; a LED package, comprising: a first LED for outputting first color light; a second LED for outputting second color light; a synchronization starting circuit coupled to the first power pin and the second power pin; an oscillator for providing a clock signal; a counter, which is coupled to the oscillator and the synchronization starting circuit and for counting according to the clock signal to generate an address signal; an image memory cell, which is coupled to the counter, receives the address signal, and provides image data corresponding to the address signal according to the address signal; and a drive circuit comprising an input port and an output port, wherein the input port of the drive circuit is coupled to the image memory cell and receives the image data, wherein the drive circuit controls an order of lighting the first LED and the second LED according to the image data, wherein the synchronization starting circuit detects voltages/currents of the first power pin and the second power pin, when a difference between the voltages/currents of the first power pin and the second power pin reaches a threshold, the synchronization starting circuit outputs a synchronization starting signal, and the counter resets upon receiving of the synchronization starting signal.
