Beschreibung
Zusammenfassung:	A luminaire motorized shade or douser mechanism includes a lamp mounted within a reflector and a motorized shade unit that opens and closes in front of the lens of the reflector. The shade unit includes a motor, two rollers, two guide cables, a sheet of opaque flexible material or fabric, and an aluminum frame. The motor drives the roller to run the shade in front of the lens to cover it and also to uncover. The motorized shade or douser mechanism is used to effectively block the light emitting from the lamp and create a condition whereas no light leaves the lens of the luminaire.
