SYSTEMS AND METHODS FOR LOW-POWER LAMP COMPATIBILITY WITH A TRAILING-EDGE DIMMER AND AN ELECTRONIC TRANSFORMER
First Claim
1. An apparatus comprising:
- a controller to provide compatibility between a load and a secondary winding of an electronic transformer driven by a trailing-edge dimmer, wherein the controller is configured to;
predict based on an electronic transformer secondary signal an estimated occurrence of a high-resistance state of the trailing-edge dimmer, wherein the high-resistance state occurs when the trailing-edge dimmer begins phase-cutting an alternating current voltage signal; and
operate in a high-current mode for a period of time immediately prior to the estimated occurrence of the high-resistance state.

Abstract
In accordance with these and other embodiments of the present disclosure, a system and method for providing compatibility between a load and a secondary winding of an electronic transformer driven by a trailing-edge dimmer may include predicting based on an electronic transformer secondary signal an estimated occurrence of a high-resistance state of the trailing-edge dimmer, wherein the high-resistance state occurs when the trailing-edge dimmer begins phase-cutting an alternating current voltage signal and operating the load in a high-current mode for a period of time immediately prior to the estimated occurrence of the high-resistance state.
