  • Light function control redundancy when changing the light intensity of pixelated vehicle headlamps
    Patent number: 11358518
    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.

  • Smart flicker-free PWM generation for multi-channel LED drivers
    Patent number: 11071184
    Abstract: The disclosure describes techniques for driving a plurality of light emitting diodes (LEDs) arranged in a parallel connection by using PWM (Pulse Width Modulation) dimming. The techniques of this disclosure describe the generation and application of a fixed phase shift map to a driver matrix based on pixel position. Each pixel corresponds to an LED light source. In the fixed phase shift map, each pixel will have a pre-defined phase shift calculated to induce a determined variation in turn-on time for geometrically neighbouring pixels to spread out current demand over time during PWM dimming.
