Abstract
Control apparatus and system for controlling an output of a constant current driver are disclosed. 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 to allow for mixing of groups of LEDs of various colors or color temperatures. The control apparatus may include a buffer load to mitigate negative impacts of turning on the lighting module after a period of deactivation. The control apparatus can also be adapted to operate as a dim-to-warm module within a lighting apparatus.
