Luminaires mean apparatus which distributes, filters or transforms the light transmitted from one or more lamps and which includes all the parts necessary for supporting, fixing and protecting the lamps, but not the lamps themselves, and where necessary, circuit auxiliaries together with the means for connecting them to the supply. Luminaires are the most common electrical and electronic products in our daily life. They should be designed to ensure safe operation without danger to personnel and the surrounding environment.
