Lumileds Tailors Luxeon IR Family for Cost Conscious High Power Applications
Lumileds introduced the Luxeon IR 2720 Line, high power emitters that set the standard for abundant radiant power delivered in an industry standard package for seamless integration in existing designs. The emitters provide high radiant power of up to 1,300 mW at 940 nm or 1,250 mW at 850 nm wavelength and feature high efficacy and a popular 120° beam angle. The 2.75x2.0 mm LEDs are undomed and especially useful for applications with package height limitations that prevent the use of domed solutions. The emitters address a wide array of cost conscious infrared applications from surveillance and machine vision to iris scanning and health monitors.

Fast Production Test of UV-LEDs
Numerous applications, for example in the medical area or in material testing, are based on precisely specified UV radiation. For UV-B and UV-C emitters, the measurement of their spectrum between 325 nm down to 200 nm is generally only possible with extended measurement times due to their low radiant flux. As such, a condition for fast testing within production is high reliability in conjunction with high optical throughput of all participating system components. Within its well-established CAS-series of premium spectroradiometers over many years, Instrument Systems has developed a novel series-type CAS 140D-157. This new system measures precisely and reliably not only within the visible spectrum, but also in the UV. Coupled with a PTFE-coated integrating sphere, the system permits for fast 24/7 production tests of UV emitters to be run.

Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared
ICFO researchers report on the development of a colloidal quantum-dot light emitting diode with unprecedented quantum and power conversion efficiencies in the infrared range. The ideal optoelectronic semiconductor material should be a strong light emitter i.e. should emit light very efficiently upon optical excitation as well as be an efficient charge conductor to allow for electrical injection in devices. These two conditions when met can lead to highly efficient light emitting diodes as well as to solar cells with the possibility to approach the Shockley-Queisser limit. Until now the materials that have come close to meeting these conditions have been based on epitaxially-grown costly III-V semiconductors that cannot be monolithically integrated to CMOS electronics.

UV LED Technology for Emerging Applications in Agriculture
The Ultraviolet (UV) LED market has expanded five-fold in the past decade and is projected to grow to over $1 billion by 2025. A key trend expected to influence the market is the ability to expand into new applications, including agriculture. UV light, at proper frequency and dose, can increase the production of active substances in medicinal and traditional plants and it can also help maintain a healthy growing environment. But to fully take advantage of UV LEDs, some major re-design considerations are required. Terrance Berland, CEO of the Violet Defense Group, the parent company of Violet Gro, will explain which considerations these are; for instance, why it is crucial to incorporate the appropriate lens material.
