Safety Issues for LED Drivers with PWM Operation Modes by Product Approvals Ltd.

Safety Issues for LED Drivers with PWM Operation Modes by Product Approvals Ltd. In many cases LED drivers manage their output power with PWM controlled switched mode power supply-topologies. The output voltages are filtered and normally DC voltages with low ripple apply at the output connectors of LED drivers. During dimming these circuits can behave very differently and therefore safety issues may arise. Siegfried Luger, CEO at Luger Research e.U. and John Showell, Product Safety Consultant at Product Approvals Ltd. have a closer look at those operation modes and the requirements on voltage limits.

LFI 2016 Touts LED Lighting and Digital Control Technology Transformation by Dr. Nisa Khan

LFI 2016 Touts LED Lighting and Digital Control Technology Transformation by Dr. Nisa Khan The 27th Annual LightFair International (LFI) conference was dominated by LED lighting coupled with internet-based control via wireless networks that continues to proliferate in today’s world. The world is increasingly becoming drenched with Internet of Things (IoT) discussions, demonstrations and for some, a certain level of implementation. Electric lighting transformed our society for over 100 years, boosting our mood and association with the environment, culture, productivity, and economic conditions. Such enormity pales in comparison to an unprecedented revolution that LFI describes as “Light and Technology in a New Language!” Read more »

LiFi - What It Is, How It Works, What It Provides, How to Apply, and Its Future Prospects

LiFi - What It Is, How It Works, What It Provides, How to Apply, and Its Future Prospects The acronym LiFi (Light Fidelity) was born at the beginning of the 2010s. Its name derives from the very well-known WiFi (Wireless Fidelity). The term VLC (Visible Light Communication) is used in the restricted instances of visible light. Mr. Luc Chassage who works for Oledcomm and the Versailles University is also Scientific Committee President of the Global LiFi Congress that offers 20 lectures dealing with all aspects of LiFi. He is a profound expert in this technology field. Mr. Chassage explains the functionality, pitfalls and hurdles to overcome, the disadvantages and advantages, and best practice to apply LiFi.

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 »
