  • Patent number: 5726629
    Abstract: A lighting fixture with a motion detector is improved by incorporating an announcement device into the lighting fixture. The announcement device is a sound recording and playback device. When a person or an object enters into an area monitored by the motion detector, the motion will be detected by the motion detector. The motion detector will then turn on the lighting fixture and the announcement device to playback an announcement or a message through an amplifier and a speaker. The announcement can either be a prerecoreded announcement by manufacturer such as a warning to intruder, a welcome greeting to visitor or guest, a short tune of music etc. or a personalized announcement recorded by a user. In the first embodiment, the lighting fixture, motion detector and announcement device are assembled together within the lighting fixture body and formed integral parts of the lighting fixture.
