Abstract
The present invention concerns a motion sensor for use with a light. The device includes a housing having an outer edge and an interior space in which a plurality of sensors are located. The sensors convert infrared into an electronic signal that is processed to detect motion. A lens located is also used which is located on an outer edge of the housing for directing infrared to the sensors which may be generally arranged in a U-shaped pattern to promote a 270 degree motion detection zone. The ends of the lens are recessed into and held in the interior of the housing a spaced distance from the outer edge of said housing so as to detect motion occurring rearward of the sensors.
