Abstract

A Visible Light Communication (VLC) transmitter that can transmit data efficiently without utilizing a blue optical filter is needed while also be able to produce high color and excellent lighting performance. A dichromatic LED configuration consisting of a data transmitter (Blue LED/Red LED) and illumination light source (LED Lime) is modulated with OOKNRZ signal and then compared to traditional LED Transmitters. From a lighting perspective, Lime-Red and Lime-Blue WLED configuration can achieve Color Rendering Index (CRI) value of 81.8 and 76.4 respectively, compared to the highest CRI value of RGB WLED that is 74.5. From a communication perspective, Lime-Red and Lime-Blue WLED can achieve data rate of 1.31 Mbps (red modulated) and 1.28 Mbps (blue modulated) compared to data rate of 1.09 Mbps by traditional Phosphorous Cool White LED. Lime-Red and Lime-Blue WLED does not have the bandwidth limitation that is prevalent in Phosphorous White LEDs, which makes these 2 configurations able to trespass the traditional data rate limit without the use of blue optical filter. Thus, by only using 2 LEDs, VLC transmitters with high CRIs, and capability of transmitting a high data rate without the use of blue optical filter is obtained.
