ABSTRACT:
The invention relates to a method for automatic switching and control of lighting to a localized area, the switching of the lighting being dependent on the presence or absence of a person in that localized area and the control of the lighting intensity being dependent on the sensed background level of lighting in that localized area. The invention also relates to a lamp fitting and to an automatic control device for controlling the light output of a light source in a "self managed" and "self controlled" energy saving luminaire.
