Light Sources News
'Internet of Lights' Meets Industrial Internet of Things
Nov 5, 2014 — A network of LED lights can be controlled with new levels of ease and precision using commercially available intelligent lighting modules and control networking solutions. The initial promise of LED lighting was to deliver more efficient lighting – not too hard a goal to reach considering that traditional incandescent and halogen lighting sources convert only five to 10 percent of energy consumed into light. But early LEDs did not provide light of a quality comparable to halogen or
LED, Microscopy Pioneers Earn Nobels In Physics, Chemistry
Nov 5, 2014 — Photonics enjoyed a brighter global spotlight than usual last month, as both the physics and chemistry Nobel prizes were awarded to recognize significant advances in light-based technologies: blue LEDs and superresolution microscopy. The physics...
German Consortium Seeks Path to Commercial Flexible OLEDs
DRESDEN, Germany, Nov. 3, 2014 — A new industry consortium will explore how to integrate organic LEDs that are flat and flexible into automobiles, aircraft and households. Dubbed R2D2, the initiative is supported by a two-year, €5.9 million grant from Germany’s Federal...
Radiant Zemax Sells Optical Design Software Business
REDMOND, Washington, Oct. 29, 2014 — Radiant Zemax will sell its Zemax optical design software business unit to Arlington Capital Partners. The sale price was not disclosed. Vice President Dr. Mark Nicholson, has been named CEO of the stand-alone Zemax business. The Radiant side of the...
Algae Carbon Flow Controlled by Changing Light Colors
LEIPZIG, Germany, Oct. 28, 2014 — Blue and red light-sensing photoreceptors can be used to control the carbon flow in diatoms, a major group of algae that generates about one-fourth of the Earth’s oxygen and perform around a quarter of global CO2 assimilation. Researchers from...
Thomas Research Products Names Regional Sales Manager
Oct 23, 2014 — ELGIN, Ill., Oct. 23, 2014 — Solid-state lighting firm Thomas Research Products has appointed Thomas Horgan as its new Southeast regional sales manager.
Grant Award Furthers Study of SWIR Light for Detecting Cancer
PISCATAWAY TOWNSHIP, N.J., Oct. 22, 2014 — Detecting cancer as early as possible can be crucial to providing effective treatment. The continuing development of a new imaging method could do just that. A Rutgers University research team, along with scientists from Singapore University of...
Blue LED Controls New Diabetes Drug
LONDON and MUNICH, Oct. 21, 2014 — A new drug for Type 2 diabetes could be controlled with violet-blue light, more effectively treating the disease through the efficient release of insulin from the pancreas.
Short-Pulse Lasers Enable Transparent Materials Processing
Oct 21, 2014 — In several industries, an increasing need exists to cut, drill and mark glass, sapphire and diamond – materials that are difficult to machine using traditional mechanical methods due to their brittleness and hardness. Their transparency at...
Shorter Wavelengths, Pulses Power Laser Manufacturing
Oct 21, 2014 — Recent laser advances are bringing benefits to manufacturing applications involving drilling, cutting and welding. More powerful diode lasers could, in the future, do more of these jobs directly, instead of being used to pump another material. The...
Intensity Increases With Loss in Microlaser
ST. LOUIS, Oct. 16, 2014 — Increasing energy loss in a laser system could actually enhance its energy, performance and efficiency.
Rare-Earth Substitute Found for LEDs
PISCATAWAY, N.J., Oct. 16, 2014 — An abundant copper compound could replace rare-earth metals in household LEDs, making them more environmentally friendly. Most commercially available white LEDS are phosphor-based but incorporate rare earth metals like cerium. Researchers from...
VerLase Patents LED Alternative
WINOOSKI, Vt., Oct. 16, 2014 — VerLase has patented technology it hopes will replace phosphors and quantum dots in multiple LED applications. Described in U.S. Patent No. 8,859,412, Versulite G incorporates wurtzite ZnCdSe quantum wells on 2-D layered semiconductor crystal. These...
Carbon Nanotube-Based Lights More Efficient than LEDs
SENDAI, Japan, Oct. 15, 2014 — A new carbon nanotube-based light source touts power consumption that is about a hundred times lower than that of an LED. A team from Tohoku University developed the new light source, which uses around 0.1 W for every hour of operation. Carbon...
Photon Emission Rate Enhanced in Fluorescent Molecules
DURHAM, N.C., Oct. 15, 2014 — Fluorescent molecules can be made to emit more photons by sandwiching them between metal nanocubes and a gold film. This film-coupled metal nanocube system features emitters embedded in the dielectric gap region. Its developers at Duke University...
Optogenetics Tests Memory Manipulation Theory
DAVIS, Calif., Oct. 13, 2014 — Optogenetics is giving scientists a better look at how different parts of the brain can work together to manipulate memories, proving a long-standing theory about retrieval of episodic memories.
Blue LED Inventors Win Nobel Prize
STOCKHOLM, Sweden, Oct. 7, 2014 — Three LED developers have been awarded the 2014 Nobel Prize in Physics.
Gas Purging Keeps UV Systems Healthy
Oct 6, 2014 — Photochemical deposition of organic films is a significant cause of performance loss in ultraviolet systems; when feasible, it can be reduced or eliminated with inert gas purging. Ultraviolet photons are highly energetic – enough to break...
Micro Thermal Camera Opens Applications to Consumers
Oct 6, 2014 — Personal thermal imaging just got affordable – but the technology can be used in various industries, too. Thermal imaging is hardly new, but most of us don’t carry thermal imagers in our pockets. Not yet. But it could happen soon, thanks...
Smile and Say, ‘Drone!’
Oct 6, 2014 — Any photographer will tell you that if it were possible to grow an extra set of hands, he would. As simultaneous scientists, artists and packhorses, photographers must know their equipment inside and out, but they must also be prepared to change...
Plessey Expands with In-House LED Assembly Line
PLYMOUTH, England, Sept. 29, 2014 — Plessey is expanding its facility here to include a new LED assembly line. This addition will allow the company to focus on its high-brightness LEDs for solid-state lighting and sensing. The expansion will cut production time and enable development...
Advances in Blue OLEDs Increase Efficiency and Lifetime
ANN ARBOR, Mich., Sept. 25, 2014 — Researchers in Michigan have discovered a way to extend the life of blue organic light-emitting diodes, which would lead to longer battery life in smartphones and lower power consumption for large screen televisions.
