How does an Incandescent bulb make light?

Inside an Incandescent bulb, electricity is used to heat up the Tungsten Filament. The electrons in the Tungsten Filament begin to jump out to a higher energy orbit for an instance and then drop back to its natural orbit, releasing light.

Understanding the basics of what light is and where light comes from is the key to understanding LED lighting and UPRtek handheld spectrometers. However, we must first get our feet wet in the world of Science, particularly Physics and Chemistry. Here explains the lighting fundamentals in layman terms, in a straightforward, concise and practical way, without any MATH! Read More
As we mentioned in artificial light FAQs, a Fluorescent Light makes light in two separate steps; electricity causes mercury vapor to emit UV light, the UV light strikes the Phosphor inner lining and causes the Phosphor to emit visible light. In both cases, the same mechanisms of Energy-Atom-Electron-Photon are in effect. Read More
As we saw on the previous FAQ“Where does light come from?”, electrons at higher orbits that drop back to lower orbits, release photons of light. In LED semiconductors, a similar strategy is at work. Electrons jump from higher energy states to lower energy states. Read More
