Abstract: A lighting control device utilizes an infrared occupancy detector in order to control the lights in a room or area. The occupancy detector monitors changes in infrared energy, which indicate movement within the area, by receiving infrared energy in a plurality of fields of view spread out over an arc of approximately 180.degree.. As a result the device may be installed on a wall of a room or area and still cover the entire area. The wide spread of the fields of view is accomplished with off-axis Fresnel lens segments arranged in series and by partially reflecting the energy received by some of the lens segments into the infrared detector.
