Light and the Internet are two great enablers of our times, and they can combine for an emerging technology called light fidelity (Li-Fi), the future of wireless communication. Li-Fi is 100 times faster than Wi-Fi and independent of congested radio frequencies and inferences from electromagnetic waves.
Smartness and connectivity is the trend that's transforming the globe across every aspect of life. Lighting is one such technology that's undergoing such a transformation. Within a few years of inception, LED has become the dominant artificial light source and has taken over all the conventional light sources.
In 2016, total global energy came from 80% of fossil fuels (coal, natural gas, and petroleum). 6% of greenhouse emissions derive from energy used for lighting. Globally, 19% of electricity use is for commercial and residential lighting.
A typical lamp using a traditional light bulb consumes 60 watts of power; however, smart lighting using light-emitting diode (LED) bulbs consumes only 10 watts to give off the same amount of light.
