  • Patent number: 7531972
    Abstract: A remote controlled porch light that has a rotating seat on a base seat, and a rotation driving seat fitting within the base seat. The rotation driving seat has a first reversible motor to rotate the rotation driving seat and lamp to the left or right. A movable lamp holder is attached rotatably to the rotation driving seat. The rotation driving seat has a second reversible motor to rotate the movable lamp holder and lamp up or down. One or more stopper pins in the rotation driving seat limit the degree of horizontal rotation of the rotation driving seat. The base seat is adjustable on an adjusting board to position the light within the center of its arc of rotation, allowing the stopper pins to limit the degree of rotation of the light so that the rotation will not damage the lamp or the house or building to which the light is attached.
