According to a paper written by scientists in the journal Monthly Notices of the Royal Astronomical Society, they used a new instrument to study how clouds affect sky brightness in urban areas, and how the future of LED lighting might change the night time sky. With Light pollution has become a growing problem, and skylines continue to grow, the night sky becomes dimmer and dimmer. However, researchers estimate that that night time sky could become bluer thanks to LED lighting. Christopher Kyba, physicist at the Freie Universität and lead author of the study, sa...

All LEDs are  driven electrically before they can emit quality light.  This is one of their basic characteristics which differentiate them from other kinds of light sources.  In this write-up, we’re going to be focusing on the DC drive circuitry for LEDs. In the first place, the battery is a typical DC source. It’s usually used for flashlights. It can as well serve as the output of a converter.  Actually, DC is quite different from AC.  The difference is that DC has much lower voltage than AC.  Hence, the regulations gov...
