A luminaire includes both the light source and the electrical components necessary for operation, and it is not exclusive to any particular type of illumination but can be used in various settings.
The term luminaire refers to a complete lighting unit that includes the light source and all necessary electrical components. It is designed to distribute, filter, or transform the light emitted by a lamp and includes all the components necessary for fixing and protecting the lamps and connecting them to the power supply.
Luminaires can vary greatly in terms of design and application, including roadway illumination, interior illumination, and stage lighting. The term does not designate the luminaire for any exclusive use but rather refers to the complete unit in any setting where it may be applied.
