Japanese UV-LED company Nitride Semiconductors has verified the inactivating effect on OC43 coronavirus (pseudo SARS-CoV-2) using three different wavelengths in the deep ultraviolet region, wavelengths 222nm, 254nm, and 275nm in collaboration with the National Hospital Organisation Sendai Medical Center Clinical Research Department Virus Center (Director Shuichi Nishimura). The Nitride team confirmed that the deep ultraviolet […]

A Japanese collaboration is claiming to have broken new ground for reducing the operating voltage of tunnel-junction deep-UV LEDs. Success has come from suppressing the incorporation of carbon contaminants in an n-type AlGaN layer that is then doped with a high concentration of silicon. The lower operating voltage promises to increase the optical efficiency of […]

Human Centric Lighting, the literal translation is human-centered lighting, people-specific lighting, translators are too talented because of lighting, if it is because of human lighting, it looks very lame, and Human Centric Lighting looks very compelling. Human-caused lighting refers to the application of lighting technology to perfectly integrate light and space, allowing people to obtain […]

When decorating an office, many companies often pay attention to the design effect of the office, cost, corporate culture integration, etc., but seldom pay attention to the lighting design, but in fact, the office is a place where employees spend eight hours a day after all. The design effect will also affect work efficiency. If […]

Abstract A direct approach to limit airborne viral transmissions is to inactivate them within a short time of their production. Germicidal ultraviolet light, typically at 254 nm, is effective in this context but, used directly, can be a health hazard to skin and eyes. By contrast, far-UVC light (207–222 nm) efficiently kills pathogens potentially without harm to […]

From next week, New York’s Metropolitan Transportation Authority (MTA) will use ultraviolet light to help remove Covid-19 from its subways, buses and commuter trains as the technology has shown to eradicate the virus from surfaces. In a report by The Sun, scientists from Columbia University and officials of the Metropolitan Transportation Authority announced on Tuesday, […]

Mean Well XBG series is a new generation LED driver with a patented circular case mechanism design for high bay light and floodlight application. The main differences compared with the last generation of HBG series are the circuit design with constant power output and complying with the latest safety regulations— isolation between output and dimming […]

Signify smart lighting training program was launched for electrical contractors. It’s a welcome idea, but the hidden message could be that the IoT isn’t as easy to implement as advertised. Meanwhile, Zigbee trumps Bluetooth. It’s no secret that the lighting industry has encountered slow going in its attempt to morph into a provider of lighting-based, […]

We all know that after more than 100 years of evolution and development, general lighting has matured from incandescent lamps, halogen lamps, fluorescent lamps, and LED lighting products. At the Frankfurt Lighting Fair, we also noticed that the difference between the products of different manufacturers is not very obvious, and the fiery filament lamp products […]
