摘要: Abstract Electric lighting has not substantially changed in over 100 years. From incandescent bulbs to fluorescent tubes, the efficiency remains low and control mostly involves on/off or dimming. The new wave of solid state offers possibility sensor-based intensity regulation, color control, energy efficiency, under varying needs environmental conditions. This paper formulates problem as an optimization balancing fidelity, human perception comfort, light field uniformity, efficiency. is solved based on propagation model, which adaptively updated with sensor feedback account for changing ambient conditions, such daylighting. We demonstrate proposed approach a smart space testbed variety use instrumented 12 tunable lights sensors, well simulated daylight. results show substantial improvement terms usage delivering good quality presence Experimental corroborate efficacy algorithms.
