  • Patent number: 9532413
    Abstract: Methods and apparatus, including computer program products, are provided for LED current generation. In one aspect there is provided a method, which may include receiving, at combiner circuitry, a first current from a light emitting diode driver circuitry; receiving, at the combiner circuitry, a second current from at least one of a capacitor or a battery; combining, by the combiner circuitry, the first current with the second current to form an augmented current, wherein the augmented current is based on at least a first value of a first resistor and a second value of a second resistor; and outputting, by the combiner circuitry, the augmented current to drive at least one light emitting diode. Related systems, articles of manufacture, and the like are also disclosed.
