A-solid state lightening based on high-output LEDs becoming more popular in this technological world. It is proverbial light bulb above the heads of some future looking engineers as it can turn the communication medium to visible light one.
The main question which arises in every engineer is that----
"Why we are not using LEDs for communication with its two states on and off as fast as billionth part of second which we can't from our human eye, and why we are not using the same for data transferring too as it have very less chances of loss of data as It have capability of transmitting signals?"
For advancement, every new LED could also be connected to network and for the same we require a network with expand ability feature for accomplishment of ubiquitous wireless communication to a device without burdening crowd already present in the network crowded by various radio-frequency bands.Visible light communications (VLC) is being refined by various industries, standards groups too to create products based on the same, since the traditional lighting market is measured in trillions of dollars and the transition to solid-state has already begun.
Visible Light Communication is totally based on Visible light and uses light emitting diodes (LEDs), for the dual role of communication and data transmissions at a faster rate with minimum losses. It is more appreciated by industries as this spectrum is free to use and have less crowd as compare to other frequencies like RF, Infra-red and some other. It will overcome various drawback too due to more efficiency With this leading edge technology, data including video and audio, internet traffic, etc, can be transmitted at high speeds using LED light.
Just as brake lights "tell" drivers to stop, VLC could send the same message

to engine-control units for collision avoidance.
VLC technology has the potential to deliver data transfer capability at hundreds of megabytes per second. Light radiation neither constitutes nor suffers from EMI making VLC a very attractive technology in places where EMI may be an issue, such as in hospitals and in air crafts etc. In addition, where security of local communication is important eg defense and fanance applications, D-Light technology offers a secure medium for communication in an office/building environment.
Dual use of LED lighting for illumination and communication would enable ubiquitous computing,

Dual use of LED lighting for illumination and communication would enable ubiquitous computing,
with separate data streams for each device in the room.
VLC Applications:
A wide range of applications would benefit from using novel visible light communications:- WiFi Spectrum Relief - Providing additional bandwidth in environments where licensed and/or unlicensed communication bands are congested
- Smart Home Network – Enabling smart domestic/industrial lighting; home wireless communication including media streaming and internet access
- Commercial Aviation – Enabling wireless data communications such as in-flight entertainment and personal communications
- Hazardous Environments- Enabling data communications in environments where RF is potentially dangerous, such as oil & gas, petrochemicals and mining
- Hospital and Healthcare – Enabling mobility and data communications in hospitals
- Defence and Military Applications – Enabling high data rate wireless communications within military vehicles and aircraft
- Corporate and Organisational Security – Enabling the use of wireless networks in applications where (WiFi) presents a security risk
- Underwater Communications – Enabling communications between divers and/or remote operated vehicles
- Location-Based Services – Enabling navigation and tracking inside buildings.
