An electric light and daylight control system with a dual mode light sensor An electric light and daylight control system for a space with a dual mode light sensor is proposed. The dual mode light sensor (106) measures and computes the amount of external light and incident electric light on its sensitivity surface. The individual measured light components (full light, electric light and external light) are transmitted to the window treatment controller (103) and the electric light controller (102). Controllers (102, 103) use this information to optimally control the lighting condition to meet user needs and reduce power consumption. both controllers (102,103) operate simultaneously and independently but are connected via the dual mode sensor (106).
