A control device may be configured to control an amount of power delivered to one or more electrical loads and provide various feedback associated with the control device and/or the electrical loads. The control device may be a wall-mounted device or a battery-powered remote control device. The feedback may indicate the amount of power delivered to the one or more electrical loads. The feedback may also indicate a low battery condition. The control device may include a light bar and/or one or more indicator lights for providing the feedback.

A system includes a mobile computing device with an image sensor that wirelessly controls at least one lighting fixture to maintain a predetermined color and intensity based on light detected by the image sensor.

The present disclosure is for a light-emitting diode light string control system, which comprises: a switching unit having a power input end, a power output end connected to the light string, and a controlled end. A control unit is connected to the controlled end of the switching unit. A second power-generating unit is also connected to the light-emitting diode light string. The light-emitting control command sent by the control unit is in a carrier wave mode to realize brightness variation of the light string, which saves costs and simplifies the control circuit. A short-circuit protection unit is employed to provide fast and reliable response in real time.

Methods and apparatus for driving an emitter array are described. A method includes determining a thermal environment profile for a plurality of emitters of the emitter array, computing a current pulse profile for at least one of the plurality of emitters based on the thermal environment profile, and applying a current pulse with the computed current pulse profile to the at least one of plurality of emitters.

An interface currents channeling circuit may be used to convert two current channels of a conventional two-channel driver into three driving currents for the three strings of LEDs. By doing so, the same two channel driver can be used for applications requiring just two LED arrays as well as three LED arrays.
