A study of the impact of VLC on the quality of lighting and display

数据传输和照明在普通发光二极管（LED）内共存，以补充基于射频的无线通信，以满足全球社会经济活动，是一种低成本/低能耗的主张，称为可见光通信（VLC）。它从根本上将被动光源转变为动态服务中心，为改进现有服务和引入新服务提供了机会。然而，为了使这个新生的VLC想法获得吸引力并实现其巨大潜力，在同一LED上相互适应数据和照明的重要优化方法变得必要。这包括研究、理解和量化照明需求和数据传输之间的相互关系，而不是目前完全忽视这一点的方法。为此，本研究将调查VLC对主要用于照明/显示的LED的能源效率、光质量和预期寿命的基本特性的影响。这项工作的发现将为优化VLC提供所需的方法，并保障LED的可靠性、耐用性和发射光质量

The co-existence of data transmission and lighting inside a common light emitting diode (LED) to complement the radio frequency based wireless communication in satisfying the global socio-economic activities is a low-cost/low-energy proposition termed visible light communications (VLC). It radically turns a passive light source into a dynamic service hub that provides opportunities to improve existing services and introduce new ones. For this nascent VLC idea to gain traction and realise its huge potential however, vital optimisation approach to mutually accommodate data and illumination on the same LED becomes a necessity. This includes studying, understanding and quantifying the inter-relationship between lighting requirements and data transmission as against the current approach that completely disregards this. To this end, this research will be investigating the impacts of VLC on the fundamental properties of energy efficiency, light quality and life expectancy of an LED that is primarily designed for lighting/display. The findings from this work will provide the required approach for optimising VLC and safeguard the LED's reliability, durability and emitted light quality
