  • Patent number: 11694601
    Abstract: Active control of LEDs, LED packages, and related LED displays by way of pulse wide modulation (PWM) is disclosed. Effective PWM frequencies for LEDs are increased by segmenting duty cycles in which LEDs are electrically activated within individual PWM periods. Segmented duty cycles may be provided by transforming or re-ordering a sequence in which control signals are provided to LEDs. As such, LEDs may be electrically activated and deactivated multiple times within each PWM period. Active electrical elements that are incorporated into one or more LED packages of an LED display may be capable of segmenting the duty cycle within each LED package. Active electrical elements may also be capable of receiving reset signals from a data stream to either initiate a reset action or pass the reset signals along to other active electrical elements of a display.

  • Patent number: 11685305
    Abstract: A vehicular light switch can change the mode of an exterior-illuminating light by rotating to different positions including an auto setting and a SMALL setting. If the position of the vehicular light switch is rotated to the SMALL setting, a momentary mechanism returns the position to the auto setting. If extravehicular brightness is less than a prescribed value and the position is rotated to the SMALL setting whilst the vehicle is stationary, a first light controller turns off a low-beam light, and turns on the low-beam light if the vehicle runs afterwards. If extravehicular brightness is less than a prescribed value and the position is rotated to the SMALL setting while the vehicle is running, a second light controller keeps the low-beam light turned on.
