SYSTEMS AND METHODS FOR LOW-POWER LAMP COMPATIBILITY WITH A LEADING-EDGE DIMMER AND AN ELECTRONIC TRANSFORMER

摘要

Methods and systems to provide compatibility between a load and a secondary winding of an electronic transformer driven by a leading-edge dimmer may include: (a) responsive to determining that energy is available from the electronic transformer, drawing a requested amount of power from the electronic transformer thus transferring energy from the electronic transformer to an energy storage device in accordance with the requested amount of power; and (b) transferring energy from the energy storage device to the load at a rate such that a voltage of the energy storage device is regulated within a predetermined voltage range.

主权项

1. An apparatus comprising a controller to provide compatibility between a load and a secondary winding of an electronic transformer driven by a leading-edge dimmer, wherein the controller is configured to:
draw a first amount of power from the electronic transformer, the first amount of power comprising a maximum amount of a requested amount of power available from the electronic transformer, thus transferring energy from the electronic transformer to an energy storage device in accordance with the first amount of power; transfer energy from the energy storage device to the load at a rate such that a voltage of the energy storage device is regulated within a predetermined voltage range; and responsive to determining that the first amount of power is greater than a maximum amount of power deliverable to the load, decrease the requested amount of power.
