How Modern Light Bulbs Work Youtube James may explains one of the most important inventions to modern lift: the lightbulb."subscribe to earth science for more fascinating science videos http:. One important point to consider here is that the filament of the light bulbs burns itself to produce light. this means that the electric current flowing through the filament heats it to the level where it starts emitting photons. the agitation and vibration of the atoms within the material of the filament produces heat energy.
How Different Light Bulbs Work Chemistry Educator And Composite The lightbulb has been shedding light in our homes and workplaces since the 1870s. and it’s been doing a sterling job considering the light it creates is a by product of the chemical processes. The incandescent light bulb is 19th century technology, and by now there's now a blinding array of electric lamps: halogen light bulbs, fluorescents, mercury. Answer. a light bulb is an electrical filament. what you have is a long piece of wire, and when you connect this to a socket, it basically completes a circuit. as electricity passes through, the electrical current excites the metal and gets it hot. as you know, an electric fire glows orange because there's electricity moving through it and it. In the case of a traditional led, that piece of matter is a semiconductor. stated very simply, an led produces light when an electrical current passes through a microchip, which illuminates the tiny light sources called leds and the result is visible light. for a complete explanation, see how light emitting diodes work.

This means that incandescent light bulbs are inefficient as a light source (in which a minority of the electromagnetic radiation is emitted in the visible part of the electromagnetic spectrum). if the filament of incandescent light bulbs could withstand hotter temperatures their efficiency would increase. By: tom harris. ©2001 howstuffworks. before the invention of the light bulb, illuminating the world after the sun went down was a messy, arduous, hazardous task. it took a bunch of candles or torches to fully light up a good sized room, and oil lamps, while fairly effective, tended to leave a residue of soot on anything in their general vicinity.
