A lighting fixture has a night light that is always on, a safety light
that provides more light than the night light, and a sensor that detects
the presence of a person within the area illuminated by the safety light.
The sensor turns on the safety light when a person is detected within
said area and turns off the safety light after the person is no longer
detected within the area. In that way, ample light is provided for safety
and security purposes while dramatically reducing the amount of energy
used.
