With a diverse virtual event, LASER COMPONENTS provides insights into all technologies from its extensive product portfolio. At LC Week (December 6 - 9, 2021), specialists from the company as well as experts from research and industry will have their say.
Each day of LC Week will have a different technological focus: On Monday, December 6, the event will start with an update on the role of UV technology - especially in disinfection.
To constantly improve the performance of UV LEDs, the material that provides the basis for these devices must be continuously optimized. Commonly, crystalline substrates are used to manufacture UV LEDs. In this context, it is necessary to epitaxially grow an aluminum nitride (AlN) layer with a smooth surface as defect-free as possible on commercially available sapphire (Al2O3) substrates.
The combination of high-temperature annealing with epitaxial growth on a sapphire surface results in aluminum nitride base layers with very low defect density. This increases the light emission and extends the lifetime of UV LEDs.
The Technische Universität Berlin, the Ferdinand-Braun-Institut, and Chalmers University of Technology annouce a new online seminar series "Advances in III-nitride Materials and Photonics Devices". From November 2021 to May 2022, a monthly online seminar on the latest developments around UV semiconductor technologies will be held.
Please register for the seminar by contacting »Tim Wernicke.
ams OSRAM (SIX: AMS), a global leader in optical solutions, together with the University of Padua, presents test results on the effectiveness of ams OSRAM UV-C LEDs against the SARS-CoV-2 virus. The corona pandemic continues to dominate daily life in many regions of the world. In addition to the various measures taken to contain the pandemic, disinfection solutions based on UV-C light are becoming increasingly popular. Previously used mercury vapor lamps are often bulky and limited in their target wavelength. Significant advances in LED technology are now opening the door to new applications. The fact that they are already a useful aid in combating the pandemic has now been confirmed by research conducted by the University of Padua on the effectiveness of UV-C LEDs from ams OSRAM.
- UV-C LEDs such as the Oslon UV 3636 from ams OSRAM inactivate up to 99.99 percent of viruses at a dose of 3,6 mJ/cm²
- Even at very low intensities SARS-CoV-2 virus can be inactivated effectively which allows more efficient system designs for e.g. air disinfection systems
- The UV-C radiation damages the nucleic acid (DNA or RNA) within the virus and therefore not only works for SARS-CoV-2, but independently from the variant
The step-down LED controller is a high-precision universal LED control chip. Due to its LED current sensing architecture, either a single or a chain of LEDs can be controlled. For the operating point of the LEDs, either the LED current, the LED light intensity or the ambient temperature can be used as measurement variables of the control loop.
At the embedded world 2022 trade fair, to be held from March 15-17, eesy-ic will highlight its “high Precision Constant Current Integrated DC-DC Converter for Highly Accurate UV-LED Controlling“.
From October 4 - 7, 2021, the Photonics Days Berlin Brandenburg will be held in hybrid format. The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) will participate with talks and in the two-day exhibition on October 6-7 in Berlin-Adlershof.
The four-day conference brings together experts from photonics, optics, microsystems technology, and quantum technology. Scientists from the Ferdinand-Braun-Institut present latest results on high-power diode lasers, UV LEDs including the corresponding irradiation systems for medical applications, and quantum technologies.
Michael Kneissl, a semiconductor physicist at the Technical University of Berlin and partner of the Advanced UV for Life consortium, develops ultraviolet-light-emitting diodes that can neutralize bacteria and viruses in drinking water and on surfaces. Physics spoke to Kneissl about his work and about the advantages that LEDs have over other disinfecting methods in the war against germs.
The current health crisis, with COVID-19 pandemic is causing an extreme high demand for disinfection solutions. Among these, devices using UV-C radiation are experiencing renewed interest. There is a lot of communication on this subject, from press releases developed by industrial companies to articles in media.
Our partner ams OSRAM, together with PISEO and Yole, had the opportunity to share their vision on the latest UV developments and market evolution.
On July 19, 2021, a study from the consortium entitled "Skin tolerant inactivation of multiresistant pathogens using far UVC LEDs" was published in the journal "Scientific Reports", one of the most renowned scientific journals. The publication shows the results of the cooperation between Ferdinand-Braun-Institut gGmbH, Charité Berlin, Universitätsmedizin Greifswald and Technische Universität Berlin. The results are of great importance especially in times of ongoing and possible future pandemics. This publication demonstrates the high level of the consortium's work on UV LEDs and their application in medicine and disinfection.
Developing a high power SMD-LED application can be costly and time consuming. To accelerate this process, OSA Opto Light developed the OEM-080 single channel LED source. It combines a lot of useful options for the researcher or product designer. As a supplier of a wide spectrum of high power SMD-LEDs OSA Opto Light offers pre mounted LEDs on star for UVA (e.g. 400, 380 and 365 nm), UVB (325, 310 nm) and UVC (280, 270 nm ) applications.
On Thursday, May 20, 2021, the BMBF-funded consortium "Advanced UV for Life" offers an online thematic workshop on "UV LEDs - Technology, Applications and Perspectives".
Prof. Thomas Ortlepp reports in his lecture "UV-LED lamps with integrated digital control" on current project results from the joint sub-project with eesy-ic GmbH and OSA Opto Light GmbH of the joint project IC4UV. The aim of the sub-project is to control the light intensity of UV LEDs with low current ripple for maximum light output, optimum illumination and optimum cooling for long service life.
For the second time, ICULTA – the 'International Conference on UV LED Technologies & Applications’ – presented a forum for the UV LED community to exchange ideas and results on cutting-edge topics. The program of last week’s virtual event covered the most recent and novel developments in UV LED manufacturing, including applications in health care, environment and life sciences, curing, and metrology. A running theme in many of the sessions was the role of UV and UV LEDs to address Covid-19, in particular the disinfection of air and surfaces. Overall, the conference served to bring together the world’s foremost LED makers, users, and researchers in an environment that fostered an excellent and productive sharing of information.
The Ferdinand-Braun-Institut (FBH) presents current research results at the virtual ICULTA 2021. In particular, the reliability of UVB and UVC LEDs has been significantly improved – an important step towards their commercial use.
