    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.

    Abstract: Methods and apparatus for changing a DC supply voltage applied to a lighting circuit are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting circuit in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured and an indication of the current level is communicated to a person who can manually adjust the DC voltage supply applied to the LED lighting apparatus by the constant voltage power supply. Alternatively, an automatic adjustment of the DC voltage supply applied to the LED lighting apparatus by the constant voltage power supply can be performed based upon the measured current level.

    Abstract: Method and control apparatus for controlling a lighting module based on a constant current level from a power source are disclosed. The control apparatus may be operable: to determine an indication of a constant current level of the power source; to determine an activation ratio in which to activate first and second groups of LEDs each cycle period based upon the indication of the constant current level; and to selectively couple the first and second groups of LEDs to the power source each cycle period based upon the first activation ratio. The first and second groups of LEDs may comprise LEDs of first and second color temperatures respectively. The control apparatus can be adapted to operate as a dim-to-warm module within a lighting apparatus.
