METHODS, SYSTEMS, AND APPARATUS FOR INTELLIGENT LIGHTING

An ambient light sensor measures an ambient light level at one point in an illuminated environment, such as a warehouse, office, shop, cold-storage facility, or industrial facility, and provides an indication of the measured ambient light level to a processor. The processor maps the measured ambient light level lo an estimated ambient light level at a different point in the illuminated environment from the measured ambient light level (e.g., a "task height" about three feet from a warehouse floor). The processor may determine the difference between the estimated ambient light level and a desired light level at the task height, and may change the artificial illumination provided by a light fixture to make the actual ambient light level at task height match the desired light level at the task height.
