A replaceable component that produces light from electricity is called a lamp. Lamps are commonly called light bulbs; for example, the incandescent light bulb. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture. The electrical connection to the socket may be made with a screw-thread base, two metal pins that fit into a receiving clamp, two metal caps or a bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor.
A "sensing bulb" is the temperature sensing device (probe) of a thermometer, RTD, or thermistor.
Pins are used to hold together assemblies to fasten two or more common components to each other and serving as hinges, axles, aligners and pivots with stops that maintain a positive limit upon the movement of components within machinery and mechanical components.
