Novel Nanoparticle Production Method Could Lead to Better LED Lights, Lenses and Solar Cells
Novel Nanoparticle Production Method Could Lead to Better LED Lights, Lenses and Solar Cells Sandia National Laboratories has come up with an inexpensive way to synthesize titanium-dioxide nanoparticles and is seeking partners who can demonstrate the process at industrial scale for everything from solar cells to LEDs. Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants for LEDs, solar cells and other optical devices.

How Much Can the Color of Nominal CCT Vary?
How Much Can the Color of Nominal CCT Vary? The threshold at which a color difference becomes perceptible is defined by a MacAdam ellipse. A MacAdam ellipse is drawn over the color space in such a way that the color at its center point deviates by a certain amount from colors at any point along its edge. The scale of a MacAdam ellipse is determined by the standard deviation of color matching (SDCM). A color difference of 1 SDCM “step” is not visible; 2 to 4 steps is barely visible; and 5 or more steps is readily noticeable. Read more »

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 »
