Description : An electrical device housing an el... An electrical device housing an electric lamp that provides illumination is known as a light fixture, light fitting, or luminaire. A fixture body and one or more lamps are found in every light fixture. The bulbs may be in sockets for easy replacement, or hard-wired in place in the case of some LED fixtures. A switch to control the light may be mounted to the lamp body or to the power wire in some fixtures. Permanent light fixtures, such as dining room chandeliers, may lack a switch and instead rely on a wall switch.Reflectors for directing light, an aperture (with or without a lens), an exterior shell or housing for lamp alignment and protection, an electrical ballast or power supply, and a shade to disperse or direct light towards a workplace are all possible elements of light fixtures (e.g., a desk lamp). Special light fixtures are designed for use in the automotive lighting industry, as well as aircraft, marine, and medical industries.
