<p>A dimmable LED driver apparatus comprising: an input interface which receives an input voltage from a power source and dimmer (201); a sensor (205) coupled to the power source and dimmer (201), the sensor (205) detects a first voltage on the input voltage and generates a sensed voltage signal representative of a voltage drop on the input voltage caused by a dimmer; a regulator and control block (212) coupled to receive the sensed voltage signal, the regulator and control block (212) generates a LED driver signal based on the sensed voltage signal; and a LED output interface on which the LED driver signal is provided to a LED array (220). A correspoding method is also claimed.</p> |
