Cree Announces Outstanding R&D LED Efficacy Combined with Superior Color Quality

Cree, Inc. records another LED industry first with the demonstration of a single high-power LED delivering nearly 1,600 lumens at 134 lumens-per-watt (LPW) with similar color quality as an incandescent light bulb. With this result, Cree achieved a breakthrough 25 percent increase in lumens per watt (LPW) over production LEDs of similar color quality under operating conditions found in real-world LED lighting applications. This important milestone coupled with Cree’s latest SC5 Technology™ platform will lead to LED systems with increased performance, lower cost and better light.

Plessey Builds LEDs in Cubic GaN on 3C-SiC/Si To Overcome The Green Gap

Plessey Builds LEDs in Cubic GaN on 3C-SiC/Si To Overcome The Green Gap

Plessey, Anvil Semiconductors and the University of Cambridge announced today that they are working together to fabricate high efficiency LEDs in cubic GaN grown on Anvil's 3C-SiC / Si substrates. Cubic GaN has the potential to overcome the problems caused in conventional LEDs by the strong internal electric fields which impair carrier recombination and contribute to efficiency droop. This is particularly true for green LEDs where the internal electric fields are stronger and are believed to cause a rapid reduction in efficiency at green wavelengths known as "the green gap". The availability of cubic GaN from a readily commercialisable process on large diameter silicon wafers is as a key enabler for increasing the efficiency of green LEDs and reducing the cost of LED lighting.

ORNL Superhydrophobic Glass Coating Offers Clear Benefits - Maybe Also for Lighting Optics

ORNL Superhydrophobic Glass Coating Offers Clear Benefits - Maybe Also for Lighting Optics

A moth’s eye and lotus leaf were the inspirations for an antireflective water-repelling, or superhydrophobic, glass coating that holds significant potential for solar panels, lenses, detectors, windows, weapons systems and many other products. The discovery by researchers at the Department of Energy’s Oak Ridge National Laboratory, detailed in a paper published in the Journal of Materials Chemistry C, is based on a mechanically robust nanostructured layer of porous glass film. The coating can be customized to be superhydrophobic, fog-resistant and antireflective.

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.

Litecool Turns LED Packaging on Its Side

Litecool Turns LED Packaging on Its Side

Litecool has produced LED packages in a vertical orientation rather than horizontal. This means that the dielectric layers only have a minor impact on the thermal performance of the LED package and allow the heat to escape more effectively through the metallic parts of the package. This has significant benefits for flip-chip packaging where dielectric layers are usually very close to the diode.

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.
