For such a useful item, the light bulb doesn’t have many parts. There are only a few main parts; the glass exterior, filament, gases and the base. The largest part is the glass it covers the filament and protects and seals in the gases. It is smooth and in a circular figure. The glass comes in many different colors and shapes. The glass is connected to the base which is made out of threaded metal. The base connects to the wall, or to an energy source. The filament is a small metal strip where the en

The only two steps you have to work a light bulb. First, screw the light bulb into a socket. Second, turn on the power the runs through your light bulb and your light will go on. While you only have to do this there are other thing going on inside the light bulb. When the electric current flows through the filament, it heats the filament to a temperature of about 3000 C. This will “burn" the filament and make it glow. The light bulb is a device that produces light by heating a material to a high temperature. The light bulb is based on the principle of incandescence, in which solids and gases emit visible light when burning or when an electric current heats them to a high temperature.

Making a light bulb is pretty easy, but there is a few complicated things. A few easier things to make is the glass bulb, coiled filament and the metal base. The filament is made out of a special metal called tungsten it has a very high melting point. When the tungsten is mixed with the right gases it has the highest melting point of any metal. There are special machines that melt the glass and metal and create the parts needed for the bulb. The harder part is trying to suck or vacuum all the air out of the bulb and replace it with argon and nitrogen. These other gases won’t burn out the filament causing the light to go out. Now days we have special machines that use nitrogen to flush out air then they replace that with a nitrogen and argon gas. With the tungsten mixed with the argon and nitrogen it can heat up to about 3,000 C and produce a lot of light. Once all the air is vacuumed out and replaces with other gases, connect all the parts and you then hav
