摘要： A vehicle LED lighting outage detection circuit is disclosed for detecting a fault in the LED light and automatically increasing the power drawn from the light power supply in response to the fault. A complementary detection circuit is also disclosed for detecting the increased power draw and signaling a fault to an operator. The increased power draw can be selected to be in the form of a pulse that settles to a lower power draw state after a time to avoid excessive and wasteful power draw. The system can be mounted in a vehicle and, more particularly, to a semi-tractor truck.

摘要： Disclosed is a backlight test circuit including N circuit blocks. Each circuit block includes M mini-LED circuits, and each mini-LED circuit includes L mini-LEDs and a switching circuit. The L mini-LEDs are connected in parallel or in serial as a mini-LED set. The switching circuit controls the turning on and the turning off of the mini-LED set according to a control signal. N, M and L are positive integers. During a backlight test, in each circuit block, at least one of the mini-LED sets is turned on. By using this backlight test circuit, the abnormal mini-LED circuit can be found. Thus, a producer can only execute a rework process for the abnormal mini-LED circuit without extra cost.

摘要： In an example embodiment, the controller is designed with a single current sensing circuit that is able to measure the current on multiple LED channels, eliminating the need for each LED channel to have its own current sensing circuit. The current sensing circuit may further be utilized with a control unit, which has an LED control model selection multiplexor (MUX) that switches between real-time closed-loop control and open-loop control.

摘要： 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.

摘要： A method for operating a light emitting diode arrangement with at least one light emitting diode includes the steps of: a) determining at least one instantaneous current-voltage value pair; b) matching the instantaneous current-voltage value pair with an original current-voltage value pair; and c) determining an updated current feed based on the matching and driving the light emitting diode with the updated current feed.
