    摘要： A light structure including a first housing having a light engine including at least one lighting scheme comprised of LEDs; and a second housing for containing driver electronics. The driver electronics including at least a mixing integrated circuit (IC) for controlling current to the at least one lighting scheme, and a near field communication (NFC) circuit having a near field communication (NFC) receiver and memory for storing instructions for sending pulse width modulation (PWM) signals from the NFC circuit to the mixing integrated circuit. The NFC receiver can receive an external command signal that the instructions stored in the memory of the NFC circuit employ to provide for an NFC control signal including at least one of the PWM signals to the mixing integrated circuit (IC). The mixing integrated circuit (IC) receiving the control signal sets current to control light characteristics for light being emitted by the light engine.
