Irradiation from deep ultraviolet LED light renders the novel coronavirus inactive, according to what could be trailblazing research. Nikkiso Co., a Tokyo-based medical equipment maker that ...

However, the sensor is not that sensitive to UV-C light, so [Akiba] had to do a bit of minor surgery on the circuitry that surrounds the sensor to tweak the output. The sensor was designed to ...

developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ...

However, traditional mercury lamps and deep ultraviolet LED light sources have shortcomings such as large device size, low resolution, high energy consumption, low light efficiency, and ...

Crucial to this process is the fact that higher-energy light (for example ultraviolet or blue) is converted to lower energy (for example yellow or red). Therefore, LEDs emitting red light cannot ...

Background: Ultraviolet (UV ... In this study, we examined the bactericidal effects of UVB-light emitting diode (LED) irradiation on oral bacteria to explore the possibility of using a 310 ...

In some people that are photosensitive, UV light from sunlight and indoor light sources can trigger a lupus flare. In addition to sunlight, ultraviolet rays are also given off by several different ...
