  • Garage door opener with light control
    Patent number: 5969637
    Abstract: A garage door operator with light control includes a garage door movement apparatus for moving the garage door in an open and in a close direction within a doorway, a light having an on and an off state, a controller for generating a door movement signal for operating the door movement apparatus and for generating a light enable signal for operating the light in one of a plurality of on and off states and an obstacle detector for detecting the presence of an obstruction in the doorway. The controller responds to the door state (traveling open, traveling closed and stopped open) in order to control operation of the door and activation of the lights. When the door state indicates the door is stopped open and the obstacle detector detects an obstruction in the doorway, the controller generates a light enable signal for enabling the light.
