ALLOS and KAUST Are Working on High Efficiency Nitride-Based Red LEDs on Si
ALLOS and KAUST Are Working on High Efficiency Nitride-Based Red LEDs on Si ALLOS Semiconductors has engaged in a collaboration with Prof. Ohkawa and his team at King Abdullah University of Science and Technology (KAUST) for realizing high efficiency nitride-based red LEDs on large diameter silicon substrates. In the collaboration the teams are addressing fundamental issues like the large lattice mismatch and the quantum-confined Stark effect (QCSE) which are preventing the adoption of red nitride-based LEDs for practical industry usage. In particular, for the emerging field of micro LED displays there is a strong demand to enable red LEDs on large diameter wafers in addition to the established blue and green color LEDs in the nitride system in order to reduce manufacturing complexity and cost.

CIE Position Statement on the Use of UV Radiation to Manage the Risk of COVID-19 Transmission
CIE Position Statement on the Use of UV Radiation to Manage the Risk of COVID-19 Transmission The coronavirus disease (COVID-19) pandemic has accelerated the search for environmental controls to contain or mitigate the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the disease. SARS-CoV-2 is usually transmitted from person to person by contact with large respiratory droplets, either directly or by touching virus-contaminated surfaces (also denoted as fomites) and subsequently touching the eyes, nose or mouth. Importantly, there is growing evidence of virus transmission via the airborne route as the large respiratory droplets dry out and form droplet nuclei which can remain airborne for several hours. Depending on the nature of the surface and environmental factors, fomites can remain infectious for several days (van Doremalen, 2020). The use of germicidal UV radiation (GUV) is an important environmental intervention which can reduce both contact spread and airborne transmission of infectious agents (like bacteria and viruses). GUV within the UV-C range (200 nm–280 nm), primarily 254 nm, has been used successfully and safely for over 70 years. However, GUV must be knowledgably applied with appropriate attention to dose and safety. Inappropriate GUV application can present human health and safety issues and produce insufficient deactivation of infectious agents. Application in the home is not advisable and GUV should never be used to disinfect the skin, except when clinically justified. Read more »

Specification and Applications for ProLight Opto's Recently Released UV-C LEDs
Specification and Applications for ProLight Opto's Recently Released UV-C LEDs Escalation of the Coronavirus outbreak have led to higher demand for Ultra-Violet C (UV-C) LED around the world. UV-C as a germicidal light source can inactivates microorganisms by destroying nucleic acids and disrupting their DNA with its short wavelength. The effective germicidal wavelength is between 200-290 nm; shorter wavelength is more efficient but is also more damaging to the human body. The major chip manufacturers make 265-285 nm as mainstream wavelength, because it can improve single chip's radiometric power and increase in sterilization efficiency. Read more »

LED Driver for High Power Machine Vision Flash
LED Driver for High Power Machine Vision Flash Automation is nothing new and its demands are rapidly increasing, either in production or inspection. More sensors are used and many are based on direct or reflected light detection. Some work in the visible range and others work in the non-visible spectrum of light. LED lighting has become the standard in most applications as the solid-state light source offers numerous advantages over other lighting technologies. However, the LED lighting system is only as good as the peripheral components and LED drivers are one key element in many applications. Keith Szolusha, LED driver applications manager and Kyle Lawrence, associate applications engineer, identified the challenges for machine vision flash applications and propose a solution example with Analog Devices' LT3932 high speed LED driver.
