Enhanced Data Transmission for Li-Fi Communications using LED Lighting

Experimental set-up of a Li-Fi receiver Despite continuous improvements in wireless communication technology, e.g. 3G, LTE, 4G etc., a looming crisis is anticipated due to a lack of sufficient radio frequency bandwidth to support the growth in demand for data transmission, in the so called “Spectrum Crunch”. Visible Light Communication (Li-Fi) offers an economical solution. LED lighting is now widely deployed and can, in parallel with its primary function, also be used for wireless communication. Li-Fi demonstrates significant improvements in security, safety and capacity over radio frequency communication, and ease of deployment as compared with fibre-optic cable. The LED link is untethered, enables links with many mobile devices, and is independent of any one host. Improvements to the data rate achievable using LEDs as the transmitter allows services based on Li-Fi concept to outperform other communication modes. Read more »

Dimming with Warmer, Cozier White Light - NXP Transforms LED Color Quality

“Sensorless sensing” technology enables accurate correction of temperature effects on LED performance, improving light quality while reducing costs When comparing LEDs to incandescent light bulbs, there is a noticeable difference in light quality: LED lamps when dimmed are perceived to be “colder” than incandescents. At CES 2013 this week, NXP Semiconductors (NASDAQ: NXPI) is demonstrating a groundbreaking solution that allows LED lamps to closely mimic the traditional incandescent light bulb, to produce a warmer, cozier white light as they are dimmed. Featuring “sensorless sensing” technology, developed and patented by NXP, this solution also has the advantage of driving down LED system costs by eliminating external temperature sensors, reducing the size of the heat sinks required for LED system cooling, and significantly improving reliability.
