DIMMER COMPATIABLE LED BULB DRIVER CIRCUIT |
摘要 |
<p>A light-emitting diode (LED) bulb for use with a leading-edge dimmer includes a shell and an LED contained within the shell. A base is attached to the bulb for connecting the LED bulb to an electrical socket. A driver circuit is configured to provide current to the LED. The driver circuit has an input filter circuit that includes a first inductor. In response to the input filter receiving a switched AC voltage from a leading-edge dimmer set to dim at 50%, the first inductor is configured to saturate. In response to an undimmed AC voltage from the leading-edge dimmer, the first inductor is configured to not saturate. The input filter also includes a bridge rectifier connected to the first inductor.</p> |
