Parts of a Light Bulb

light bulb

a device made of glass, ceramic, and metal parts that can by inserted into a lamp or other socket, in which electrons pass through in order to provide light

filament

a thin wire, usually tungsten, that is heated by the passage of an electrical current and produces light in a light bulb

wire attachment point

the area where one support wire is fused to the metal middle of the light bulb, so electrons can pass through

metal tip

the bottom part of a light bulb where a support wire is fused, so electrons can pass through

ceramic insulator

the ceramic part of a light bulb that separates the attachment point and the metal tip, so electrons cannot pass through

glass support or mount

the part of the bulb that separates and holds up the support wires

support wires

two thin wires, that support the filament, and allow electrons to pass through, in a light bulb
