Enhanced Data Transmission for Li-Fi Communications using LED Lighting
Enhanced Data Transmission for Li-Fi Communications using LED Lighting 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
Dimming with Warmer, Cozier White Light - NXP Transforms LED Color Quality 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.

MIT Study: Significant Energy Savings through User-Controlled Efficient Lighting Systems
MIT Study: Significant Energy Savings through User-Controlled Efficient Lighting Systems These days, in newer buildings it’s often hard even to find a plain old-fashioned light switch. Often, the only controls are automatic motion-detector switches that turn off lights when people have left a room — or when they sit too still — or else daunting control panels with arrays of sliders and buttons. But some researchers at the MIT Media Lab are aiming to put the controls back in people’s hands, in a way that provides sophisticated and continuous control and could slash lighting bills by more than half.

Off-Line LED Control Circuit
Off-Line LED Control Circuit Resonant mode topologies offer many benefits over traditional buck, boost and flyback solutions. These include soft-switching, higher operating frequencies, higher power density and higher efficiency. Electronic ballast designs for fluorescent lighting applications have already been taking advantage of these benefits for many decades. Much can be learned from electronic ballast circuits and applied to LED driver circuits. This article compares the load requirements for fluorescent lamps and LEDs, explains the functionality of a new dimming electronic ballast control IC, and describes a new resonant mode control circuit for LEDs that uses the new IC.

Electrical Considerations of LED Bulbs
Electrical Considerations of LED Bulbs Governments all over the world regulated the future use of the inefficient incandescent lamps. For example, the member states of the European Union agreed to a phasing out of incandescent lamps by 2012. The initial European-wide ban applies the first step to “nondirectional” light bulbs. The first types of bulbs to be banned are frosted (non-clear) bulbs and clear bulbs over 100 W, which will be phased out completely by September 2009. The power limit will be moved down to lower wattages, and the efficiency levels raised by the end of 2012. Read more »
