Abstract: A system for sensing and maintaining the light level within an area. The invention comprises multiple lux sensor readers that function to measure the current light level within an area. One or more controllers are used to control the dimming level of each light source in accordance with the readings received from the plurality of lux sensors. The readings are averaged such that over time any extreme readings are averaged out. The light level of the plurality of light sources is adjusted in accordance with the averaged readings. This virtually eliminates areas in the room where the light is too dim or too bright and serves to average out any manufacturing and component tolerance differences between devices. In addition, the invention comprises the optional assignment of a weight factor to each reading or average to further provide the ability to give more importance to certain regions in the room over others thus further assisting in eliminating areas where the light is either too dim or too bright. The system includes control units, controllers, controls for window, skylight, light pipe and shading, HVAC controls, lighting loads and light sensors (lux readers) that are used to construct the lighting control system of the present invention. Readings from the one or more lux sensors are processed by one or more controllers and in response thereto, one or more commands are generated for directing the actions of controllers to which the lighting loads are attached.
