A chandelier light fixture
A light fixture is an electrical device used to create artificial light or illumination in architecture. A complete lighting fixture unit consists of the light source or lamp, the reflector for directing the light, an aperture (with or without a lens), the outer shell or housing for lamp alignment and protection, a electrical ballast, if required, and connection to a power source. A wide variety of special light fixtures are created for use in the automotive industry, aerospace, marine and medicine.
Light fixtures are classified by how the fixture is installed, the light function or lamp type.
