  • Patent number: 9875624
    Abstract: A light emitting diode (LED) device includes a control circuit configured to apply a non-uniform output power pulse shape to increase illumination intensity in at least a part of the pulse without consuming additional power. Different intensity levels may be provided in series in the non-uniform output power pulse shape. The non-uniform output power pulse shape improves lighting while maintaining the same power consumption as a reference light pulse having a uniform shape.
