Abstract
LED driver apparatus and methods may include a sensing circuit for adjusting an output based on either a pulse width modulation dimming control or an analog dimming control. An LED driver apparatus and methods may also include a sensor for a parameter such as temperature and for recording such parameter, for example as a function of time. A setting unit for an LED driver apparatus can be used to sense and/or adjust settings in the LED apparatus even when the LED apparatus is not independently powered.
