  • Light apparatus with parallel-arranged LEDs and per-LED drivers
    Patent number: 11785684
    Abstract: A light apparatus includes an array of light-emitting diodes (LEDs) in parallel arrangement, in which the LEDs have respective first terminals coupled together for connection to a supply node of a power source that provides the drive current to the LEDs during operation. Driver circuity is disposed between respective second terminals of the LEDs and a return node of the power source. The driver circuitry includes a respective LED driver for each of the LEDs, and each LED driver includes (1) a transistor connected to the second terminal of the respective LED, and (2) a resistor in series between the transistor and a return node of the power source, the transistors of the LED drivers having respective control inputs for receiving respective LED drive signals to control operation of the LEDs.
