Night Light Patents (Class 362/641)
  • Patent number: 7165864
    Abstract: 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.
