Patents: are they a blessing or a curse for the LED industry?
The patent system is intended to encourage invention and innovation and should benefit the LED industry, provided that the need for litigation can be alleviated by licensing and avoiding infringement, according to Alice Martin and John Wappel of Barnes & Thornburg, LLP.

Lighting industry still learning how to apply advanced LEDs
Some lighting designers view LEDs as a troublesome technology that is only really useful for color-changing applications, but at the same time the LED community is moving to address many of the concerns voiced by the lighting industry. Tim Whitaker reports from the Applying Advanced LEDs conference.

Photonic quasicrystals boost LED emission characteristics
Custom photonic quasicrystal structures can help to efficiently extract light from LEDs and place it into a desired emission profile, according to Majd Zoorob and Gregory Flinn.



Optical design software improves design and validation of LED-based systems
Simulation software can significantly improve the design process or LED- and OLED-based systems, and virtual validation without physical prototyping allows engineers to save time and money, as Jean-Baptiste Haumonte of Optis describes.



Full-color video LED billboards feel the impact of alternative technologies
Smaller LED display manufacturers could struggle in the face of decreasing prices and the emergence of competing technologies such as digital ink, according to Peter Pihos of EDG Research and Consulting.

High-power LEDs provide illumination and treatment in medical applications
