Abstract
A light emitting diode (LED) device includes micro LEDs and one or more macro LEDs formed on the same semiconductor substrate. Each micro LED emits modulated light to perform communication with another device. Each macro LED emits light to illuminate an environment surrounding the LED device and the size of the macro LED is relatively larger than the micro LED. The LED device may further include a notch filter to filter light generated by the macro LEDs so that the light from the macro LEDs do not interfere with communication performed by the micro LEDs.
