    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: Circuits for sensing current levels within an apparatus are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting apparatus 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 by determining a voltage level across a known resistor and calculating the current level. To prevent the known resistor from causing a significant reduction in the efficiency of the overall light engine, the circuit includes one or more transistors in parallel with the known resistor to reduce the effective resistance in the LED circuit during times that the current is not being sensed.

    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: The present disclosure provides a lighting apparatus generally comprising an LED module having LEDs and a control module to control the LED module. The LED module has pins positioned on an underside thereof to connect to corresponding pins on the upper surface of the LED. The LED module having a passive electrical component whose value can be detected by the control apparatus. In response to said detection, the control apparatus can perform a variety of functions, including configuring the LED module. The lighting apparatus is further comprised of a reflector, the reflector positioned within a central aperture of the control module and surrounding the LEDs. The reflector serves to focus light from the LEDs and can be secured to a diffuser releasably lockable to the lighting apparatus, the diffuser to diffuse the light from the LEDs.
