How a Li-Fi based system is designed
A Li-Fi system is built primary with these four sub-components: A bulb, a Radio Frequency Power Amplifier (RFPA), a Printed Circuit Board (PCB), and an Enclosure. The center of a LiF system is based on the sub-assembly of a bulb, which is inserted in dialectric material. The Printed Circuit Board or PCB controls every electric signal of the lamp and contains a microcontroller that manages the different functions of the lamp. The Radio Frequency Power Amplifier Circuit or RFPA is the one that generates the radio frequency signal which is later converted into an electric field. The dialectric material has two functions; it acts as a waveguide for the radio frequency energy radiated by the Power Amplifier and also helps concentrate the electric field focusing the energy in the bulb. All the components are contained in an aluminum enclosure. The whole system works because the concentration of energy in the electric field gets transformed into plasma which produces an intense beam of light in high intensity.
