    Abstract: A vehicle headlamp control circuit may be configured to control a vehicle headlamp comprising a plurality of lighting elements. The vehicle headlamp control circuit may comprise a first communication interface configured to receive a first signal comprising a first set of values for driving the plurality of lighting elements, and a second communication interface configured to receive a second signal comprising an intensity threshold. The circuit may be configured to determine a composite intensity associated with the first set of values and drive the plurality of lighting elements using the first set of values if the composite intensity associated with the first set of values satisfies the intensity threshold.

    Abstract: A system includes a light-emitting diode (LED) circuit comprising a set of LEDs arranged in a formation, wherein the set of LEDs comprise a set of LED clusters; and a controller. The controller is configured to: control, according to a first LED control mode, whether each LED of the set of LEDs is turned on or turned off; and control, according to a second LED control mode, whether each LED cluster of the set of LED clusters is turned on or turned off, wherein the first LED control mode requires the controller to use a first amount of computing resources, wherein the second LED control mode requires the controller to use a second amount of computing resources, and wherein the second amount of computing resources is lower than the first amount of computing resources.

    IPC: H05B33/08

    Abstract: An electronic circuit and a method are disclosed. The electronic circuit includes an LED circuit, wherein the LED circuit (1) includes: an input (11, 12) configured to receive an input voltage (VIN); a drive circuit (2A) connected to the input (11, 12); and an LED module (3A) connected to the drive circuit (2A) and comprising an LED string (41) with at least one LED. The drive circuit (2A) is configured to monitor the LED module (3A) for the occurrence of an LED short in the LED string (41) and to change from a normal mode to a defect mode upon detection of the LED short, and the drive circuit (2A) is configured, in the defect mode, to operate the LED string (41) in at least one defect cycle that includes deactivating the LED string (41) for a deactivation period, activating the LED string for an activation period, and checking for the persistence of the LED short in the activation period.
