Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared
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.

Evaluating Performance of LED-Based Luminaires
Evaluating Performance of LED-Based Luminaires LpR 69 Article, page 48: The wide spread of performance data supplied by manufacturers make it difficult for the professional user to reach an “apple-to-apple” comparison, especially if the data is not based on standardized metrics. This is however critical for the preparation of lighting projects or tender specifications. Experts from LightingEurope have therefore developed a guidance document which recommends a fixed set of performance data for LED based luminaires, with particular emphasis to the useful life and the data which is necessary for lighting application design.

How to Use the Technologies for Adaptive Lighting
How to Use the Technologies for Adaptive Lighting The technologies to provide adaptive lighting are already in the marketplace and are accepted by some jurisdictions. Nonetheless, we have an inadequate understanding of how best to use these technologies, meaning that installations might not serve users well, and in the worst case, might lead to harm. Lighting researchers can generate the knowledge needed to support the best application of adaptive lighting technologies. The International Commission on Illumination (CIE) understands the importance and urgency to deal with problems of adaptive, dynamic and intelligent lighting in all application fields. Hence, this topic is a highlight of CIE’s research strategy. Read more »

TE Connectivity Introduces Corcom MRI LED Lighting Filters
TE Connectivity Introduces Corcom MRI LED Lighting Filters In medical applications very often strict EMI suppression and clean power is required. One especially critical application is Magnetic Resonance Imaging (MRI). Unfortunately standard LED drivers and LED lighting products don't provide sufficient EMI suppression. Even LED lights outside the MRI room may influnce the MRI equipment. Especially designed filters can eliminate this problem. TE Connectivity’s new Corcom MRI LED lighting filters is such a product.
