SYSTEMS AND METHODS FOR LOW-POWER LAMP COMPATIBILITY WITH A TRAILING-EDGE DIMMER AND AN ELECTRONIC TRANSFORMER |
摘要 |
<p>An apparatus may include a controller to provide compatibility between a load and a secondary winding of a transformer driven at its primary winding by a dimmer, wherein the controller is configured to: determine from a transformer secondary signal whether the transformer comprises a magnetic transformer or an electronic transformer; and select a compatibility mode of operation from a plurality of modes of operation based on the determination of whether the transformer comprises a magnetic transformer or an electronic transformer. A method for providing compatibility between a load and a secondary winding of a transformer driven at its primary winding by a dimmer may include determining from a transformer secondary signal whether the transformer comprises a magnetic transformer or an electronic transformer and selecting a compatibility mode of operation from a plurality of modes of operation based on the determination of whether the transformer comprises a magnetic transformer or an electronic transformer.</p> |
