摘要： An electric light and external light 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 electrical light incident on its sensing surface. The individual measured light components (total light, electric light and external light) are transmitted to the window treatment controller (103) and the electric light controller (102). The controllers (102, 103) use this information to optimally control the lighting condition to meet user requirements and reduce energy consumption. Both controllers (102, 103) operate concurrently and independently, but are linked via the dual-mode sensor (106).

摘要： The disclosed embodiments relate to a daylight harvesting system (1). The daylight harvesting system comprises a light distribution device comprising a light inlet (2) for receiving incident light (3), and a light outlet (4) for providing output light (5) received by the light inlet into an interior space. A light sensor (6) is arranged to receive and measure a light level of the incident light and to provide a measurement signal representative thereof. Control circuitry (7) is arranged to receive the measurement signal, and to provide a control signal based on the measurement signal to an artificial light source (8) placed at the light outlet. The light sensor is placed relative the light inlet such that the incident light received by the light sensor exclusively is affected by the incident light as received by the light inlet
