Abstract:
A LED driver, a LED driving method and a controller for LED driver are discussed in the present invention. The LED driver detects the phase of the input signal which is phase cut by a triac from a pre-E-transformer. The LED driver regulates the current flowing through the LED strings by varying the phase of the input signal.
