PLEDs ensure compatibility of existing ballasts and LED lights

PLEDs ensure compatibility of existing ballasts and LED lights
Littelfuse have introduced a series of PLEDs with an ultra-low holding current (just 21mA) that makes the ballast drivers widely used in the output of fluorescent tubes compatible with modern replacement LED strings or tubes. This eliminates the need to scrap otherwise still-working ballasts when replacing fluorescent lighting tubes with LED strings or tubes.

Power project working on LED replacements for UV light sources

Power project working on LED replacements for UV light sources
A total of five research institutes and companies have been working on 'UV Power' since February 2017. This is a collaborative project funded by the German Federal Ministry of Education and Research (BMBF). The partners have made it their goal to provide high-power UV LEDs to cover a wide variety of applications. These LEDs will eventually replace conventional UV light sources, which often contain toxic mercury, in areas such as production, disinfection, the environment, life sciences and medicine. UV LEDs are also likely to open up new areas of application.
