WebJan 3, 2024 · The compound absorbed energy and then slowly released it over time. The energy wasn't really something you could see, so additional chemicals called phosphors were added to enhance the glow and add color. Phosphors take the energy and convert it into visible light. Modern glow in the dark stuff uses strontium aluminate instead of zinc … WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. WebOct 16, 2024 · The blue component of light between 380nm and 500nm is also known as high-energy visible (HEV) light. In particular blue-violet wavelengths between 380nm and 440nm are seen as potentially damaging and have been implicated as one of the possible causes of photoretinitis, i.e. damage to the retina caused by high-energy incident light. how do brushless drills work
