Abstract
The present invention is directed to circuit and apparatus for controlling an output of a constant current driver. A control apparatus is coupled between a constant current driver and a load, such as a lighting module, in order to add functionality to the overall system. The control apparatus is powered by the constant current driver and may control the dimming of the constant current driver by controlling the 0-10V dim input into the driver. The control apparatus may comprise one or more switching elements between the constant current driver and the load. The control apparatus may interface with external devices or communication networks in order to receive control commands or information that may be used for control purposes. Overall, the control apparatus is implemented into the system to enable added-value features that the constant current driver would otherwise not be able to implement.
