A Standardized Open Platform Is Key to the Future of Smart Lighting System Design

A Standardized Open Platform Is Key to the Future of Smart Lighting System Design The LED industry’s pace of evolution is more prevalent now than it has ever been. The shift from traditional standalone LED bulb lighting to fully connected digital LED systems is upon us and is transforming the industry for the better. For years, LED manufacturers have focused on driving cost down rather than focusing on improving quality, but with the advent of connected lighting, smart lighting and human-centric lighting, the focus has shifted back onto quality. Dr. Kyeongik Min, Principal Engineer in the LED business team at Samsung Electronics, explores how the LED industry can accelerate the transition from standalone lighting to fully connected lighting through a deeper understanding of current market trends.

Method to Control Light Propagation in Waveguides

Method to Control Light Propagation in Waveguides A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. To demonstrate this technique, they built photonic integrated devices that not only had record-small footprints but were also able to maintain optimal performance over an unprecedented broad wavelength range.

Prof. Shuji Nakamura - The Future is Laser Lighting

Prof. Shuji Nakamura - The Future is Laser Lighting PROF. NAKAMURA SAID: "For violet LEDs we reach about 50-100 Acm-2 but the laser diode uses 3-10 kAcm-2 which is about 1,000 times higher than blue LEDs. This leads to very tiny chips in combination with the same phosphors such as YAG types. The light output is about 1,000 times higher than conventional LEDs with the same chip-size". Read more »

National Lighting Bureau: AMA Lighting Recommendations are Based on Wrong Metric

National Lighting Bureau: AMA Lighting Recommendations are Based on Wrong Metric The American Medical Association’s (AMA’s) warnings about too much “blue light” at night are seriously flawed: The AMA developed them using a measuring tool that does not measure the specific kind of “blue light” the AMA is concerned about. Nonetheless, according to speakers at the National Lighting Bureau’s Annual Lighting Forum, some jurisdictions and public-transportation departments nationwide believe, mistakenly, that they will reduce human-health risks by adopting the AMA’s recommendations. Making matters worse, when applied to street and roadway lighting, the AMA recommendations could erode public safety by diminishing driver and pedestrian visibility, while also reducing energy efficiency or increasing energy costs.

Thermal Management of an LED Light Source for Microscopes

Thermal Management of an LED Light Source for Microscopes Thermal management is a challenge for every LED and LASER solution. Microscope lighting solutions have some very critical requirements, especially if they concern medical applications. ESCATEC in Heerbrugg, Switzerland has a lot of experience in that field and covers all relevant technical disciplines. Wolfgang Plank, head of the MOEMS Future Laboratory and cleanroom, and Gerd Harder, Key Account Manager, give insights on the design process, thermal simulation and production of an LED light source for Leica Microsystems’ Ophthalmic Microscope Proveo 8.

Nanorod LEDs with Two Functions Could Make Multifunctional Displays

Nanorod LEDs with Two Functions Could Make Multifunctional Displays Cellphones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, thanks to new LED arrays that can both emit and detect light. Made of tiny nanorods arrayed in a thin film, the LEDs could enable new interactive functions and multitasking devices. Researchers at the University of Illinois at Urbana-Champaign and Dow Electronic Materials in Marlborough, Massachusetts, report the advance in the Feb. 10 issue of the journal Science. Read more »
