It is not uncommon to examine good lightweight bulbs which will be controlled from a smartphone. they’ll dynamically modification color and switch themselves on and off at regular times. However, there’s another kind of good lightweight bulb that solves a very totally different downside.
Most wireless communication, as well as Bluetooth and local area network, happens within the oftenness (RF) spectrum. sadly transmission within the RF spectrum is restricted because of regulation and interference (Lo, 2004). Since a lot of and a lot of devices have a desire for wireless communication, particularly with the increase of the web of Things, the RF spectrum is turning into jam-pawncked. One answer to the present is to appear into totally different spectrums for communication, like the visible radiation spectrum. The technology that achieves this can be called visible radiation Communication (VLC).
VLC is that the method of transmission information by victimisation visible radiation waves rather than the standard radio waves (Lo, 2004). VLC is appealing as a result of it’s in Associate in Nursing unregulated information measure, unlike RF, that makes adoption easier. VLC conjointly incorporates a potential three hundred rate of information measure, giving multi-gigabit per second communications (Rajagopal, 2012).
VLC could be a promising technology on its own, however implementing it in good lightweight bulbs is wherever real edges are found. lightweight bulbs already area unit employed in several indoor areas to produce lightweight, however with the proper technology they might get replaced by good lightweight bulbs. These bulbs would offer identical lightweight however conjointly wireless web property (Kavehrad, 2010). this is able to lead to less RF interference, less dedicated communications hardware and fewer wasted power.
