Smart Lighting Solution using LiFi Technology in Intelligent Buildings

Abstract

Intelligent buildings are an important part of sustainability practices that the establishment of intelligent buildings is a way to promote sustainability. The technology of that buildings includes advanced systems that represent different building services, The various devices, and systems in the building are connected through a wireless communication network to be all controlled from anywhere and create the required interaction between them as an “integrated system”. This system can improve the energy efficiency of the building and reduce the cost of construction and maintenance. To achieve this, an advanced and high-speed communication system must be available that matches the development of smart systems and artificial intelligence of smart devices.LIFI (Light Fidelity) technology depends on a data transmission technique that uses visible light and ultraviolet and infrared lights to carry out the communication. It is one of the unique options proposed as a new form of data transmission, LiFi is a wireless technology that holds the key to solving challenges faced by 5G. LiFi can transmit at multiple gigabits, is more reliable, virtually interference-free, and uniquely more secure than radio technology such as Wi-Fi or cellular.This paper focuses on the integration between building services and smart devices, using high speed, low voltage data networks, connected with LiFi technology for wireless communication to originate intelligent buildings The smart LED lighting network will be utilized for Data transfer inside, and outside intelligent buildings that are to be connected to Centralized Drivers through a structure cabling system. Instead of using special LED lighting units that work for the LiFi system, which are expensive and not widely available in the commercial markets, an RJ45 converter will be used to connect it to the widely available commercial lighting units directly or through the splitter, eliminating the need to use special lighting fixtures for the LiFi system to operate in the right way.
