Abstract

Visible light communications (VLC) uses modern solid-state LEDs to broadcast information. Emerging white-light LEDs allows the combination of lighting and optical wireless communication in one optical source. In this paper, a new LED lighting using one-chip-type white LED is proposed for efficient illumination and optical wireless communications. Performance analysis such as horizontal illuminance, 3-dB cut-off frequency, inter-symbol interference, signal-to-noise ratio and bit-error rate shows the effects of the shapes of LED lighting. Performance of the proposed LED lighting under the existence of obstacles is superior to that of the existing LED lighting in illumination and optical wireless communication.

가시광 통신은 반도체 LED를 이용하여 정보를 브로드캐스트 하며, 백색광 LED는 조명과 광무선 통신을 하나의 광원을 사용하여 제공할 수 있다. 본 논문에서는 단일칩 백색광 LED를 활용하여 조명과 통신에 적합한 조명기구를 제안한다. 백생광 LED 조명기구의 구조에 따른 수평 조도특성, 무선채널 대역특성, 심볼간 간섭현상, 신호대 잡음비 및 비트 에러율을 분석함으로써 장애물이 있는 경우 제안한 LED 조명이 기존의 조명보다 우수한 조명 및 통신 채널을 제공함을 보이고자 한다.
