  • Series connected parallel array of LEDs
    Patent number: 11359775
    Abstract: Disclosed is a plurality of LED packages that are connected in a parallel array. A plurality of parallel arrays can also be connected in series to form a light string. The LED packages present a standardized impedance in which the resistive values of a series resistor and a parallel resistor are selected to moderate the flow of current when the LEDs become either shorted or open circuited.
