Abstract: A triple-sensor motion detector is provided for illuminating the approach to a display case or other object. The triple-sensor motion detector provides a field of detection that spans the front width of the case, yet does not include the areas along the sides of the case. The detector reduces inadvertent triggering of the illumination by persons approaching the side of the case or approaching another case on the other side of an aisle.
