US Patent 7804252 Two way lighting control system with dual illumination sources

A two way lighting control system with dual illumination sources, including a lighting unit, a photocell, a motion sensor, and at least one light source base. The lighting unit includes two light source loads. The high wattage light source load is the first light source, and the low wattage source load is the second light source. The illumination of the first light source load is greater than the illumination of the second light source load. The first light source load is electrically connected with the motion sensor via the base, and then is further electrically connected with the photocell to form the first circuit loop. The second light source load is electrically connected with the photocell via the base to form the second circuit loop. Thereby, the present invention can satisfy consumers' requirements of providing both high illumination light and low illumination light with energy saving benefit as needed.
