摘要:
The present disclosure provides a method for adjusting output of a lighting system. In one example, the method comprises providing to an integrated circuit a rectified sine waveform of a power source, providing to the integrated circuit a dimming signal corresponding to a dimming profile, modifying the rectified sine waveform into a truncated rectified sine waveform in accordance with the dimming signal, and selectively turning on or off a number of light emitting diodes in accordance with the truncated rectified sine waveform to produce a light output.

The present disclosure provides a lighting system. In one example, the lighting system comprises a circuit board including plural light emitting sets, each of the light emitting sets including one or more light emitting diodes, plural integrated circuits configured to receive a rectified sine waveform of a power source, and a dimmer circuit electrically coupled to the integrated circuits and configured to transmit a dimming signal to the integrated circuits. Each one of the integrated circuits is electrically coupled to a respective one of the light emitting sets. Each of the integrated circuits is configured to modify the rectified sine waveform into a truncated rectified sine waveform based on the dimming signal. Each of the integrated circuits is configured to turn on or off a number of the light emitting diodes included in a respective one of the light emitting sets based on the truncated rectified sine waveform.

In some examples, non-lighting application controller technology includes methods and apparatuses. In other examples, the technology includes a non-lighting application controller system. The system includes one or more light fixtures. Each light fixture of the one or more light fixtures has one or more non-lighting elements, such as a speaker, alarm, motor, and camera. Each light fixture of the one or more light fixtures is electrically coupled via a power line. Each light fixture of the one or more light fixtures includes a conversion module configured to convert instructions between power line communication and non-lighting control communication, a communication module configured to communicate the power line communication over the power line, and a non-lighting element controller configured to control the one or more non-lighting elements in a respective light fixture based on the instructions.

In some examples, automatic light fixture address technology includes methods and apparatuses. In other examples, the method includes receiving a disable forward control command to disable data forwarding through the light fixture; receiving an enable forward control command to enable data forwarding through the light fixture; transmitting address data for the light fixture based on the enable forward control command; and forwarding one or more additional enable forward control commands based on the enable forward control command.
