Abstract: A smart lamp system and method for monitoring a status of LEDs. The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a power-line communication (PLC) transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver.

Abstract: The present disclosure relates to a driving circuit individually performing drive control of light-emitting elements having cathodes with the same potential. The driving circuit includes driving circuit units provided in one-to-one correspondence with the light-emitting elements. Each driving circuit unit includes a switching element, a first energy-storage element, a current-control element, and a current-interrupting element. The current-control element connects in parallel to the semiconductor light-emitting element. In the first energy-storage element, a first electrode connects to a first node, and a second electrode connects to a first constant-potential line. In the switching element, a first current terminal connects to a second electrode, and a second current terminal connects to a second node. The second nodes connect to the second constant-potential line without short-circuiting each other by the current-interrupting element. The current-interrupting element interrupts or suppresses current during a period in which the switching element is in ON-state.

Abstract: An LED string control system includes an LED string and a control module. The control module provides a first voltage level according to a first digital logic of a light command, and provides a second voltage level according to a second digital logic of the light command to form a control signal. Based on consecutive first digital logics and/or second digital logics of the light command, the control module adjusts a voltage level of the control signal to a third voltage level as a distinction voltage level for distinguishing two consecutive first digital logics and/or two consecutive second digital logics.

Abstract: An LED arrangement having a LED string and a smoothing capacitor connected in parallel. A controllable voltage limiter is able to limit a voltage across the LED string to selectively prevent the LED string from outputting light. As the LED arrangement is turned ON, the controllable voltage limiter may activate so that the smoothing capacitor can be charged with a high current without activating the LED string.

Abstract: Circuitry configured to deliver an adjustable discharge current to a compensation node of a power converter that supplies a load, which may speed up the power to the load on the new steady state condition, while maintaining the stable response time of the power converter. A driver circuit may measure current to the load and perform overshoot protection for the load. The overshoot protection may also generate a pattern of detectable square wave pulses. The circuitry of this disclosure may adjust the discharge current based on a duration of the pulses in the pattern of pulses, as well as based on a pulse density of the pulses.
