HALOGEN WORK LIGHT BULBS HOW TO

This process is called fluorescence and is the namesake of the bulbs. The white coating on the inside of the glass absorbs the ultraviolet light and re-emits it as more visible light. And the atoms then emit visible and ultraviolet light. Electrical current flows from one electrode to the other, and when the electrons that make up the current bump into mercury atoms in the gas, the energy of the collision makes the atoms get excited. Fluorescent bulbs are basically gas-filled tubes with electrodes at both ends. The chemistry of the halogen gas allows it to capture stray tungsten atoms that evaporated off the filament and shepherd them back to where they belong, which both prolongs the life of the filament as well as keeps the inside of the ball clean and clear. Halogen bulbs have the same tungsten metal filament as typical incandescent light bulbs, but they contain a little bit of halogen-based gas in the bulb, as well. Each one makes its own clever use of physics to achieve the life goal of a light bulb- converting electrical current into visible light. So the incandescent light bulb is 19th-century technology, and by now, there's a blinding array of electric lamps- halogen light bulbs, fluorescence, mercury and sodium vapor lamps, LEDs, and so on. Bare filament electric lamps were first demonstrated around 1800 by Humphry Davy, and the glass bulb was added later to keep oxygen away from the wire so it could glow for a long time without actually burning up. Just run a bunch of electrical current through a thin wire until it heats up enough to start glowing.
