LED lights above arc lamps are arrayed in five areas, namely, below, east, west, south, north. Figure 6 is the full range of sub-control intelligent lighting system schematic. Fig.6（a）Outline structure (Overlook) Fig.6（b） Outline structure (Three-dimensional visual) 3 SOFTWARE DESIGN The main controller program flow chart is shown in Figure 7. The program of the main controller includes module initialization, gathering lighting information, response processing and so on . The main task is to process digital signal from the sensor. The first step is to choose the direction and then obtain information from the direction of the light. if the light intensity in this direction exceeds ordinary lighting requirements, the microprocessor will reduce the number of lights in the area, whereas will increase the number of lights in the area; as a result, the indoor light intensity will be maintained in the required range for general lighting requirements.
