Dynamic control method for indoor green artificial light environment in buildings
This article focuses on the closed assembly line workshop in the electronic information manufacturing industry and proposes a dynamic dimming method based on light non-visual effects and intelligent optimization algorithm to address the shortcomings of high energy consumption and low comfort in the artificial light environment of the workshop.Firstly,based on the interior lighting scene of the assembly line workshop,the corresponding dynamic dimming strategy is developed.On this basis,the mathematical model of light regulation is established by combining LED lamps with pulse width modulation technology and light simulation in DIAlux.Secondly,in order to improve the optimization ability and robustness of the Antlion algorithm,an improved Antlion algorithm based on PWLCM chaotic mapping,Levy flight,firefly disturbance and adaptive hybrid mutation mechanism is proposed,and the improved Antlion algorithm is used to solve the mathematical model of light regulation and achieve the optimal control of light.Finally,the algorithm comparison experiment,illumination control accuracy experiment and illumination simulation experiment are designed.Experimental results show that the improved Antlion algorithm has stronger optimization ability and higher stability than other algorithms.The dynamic dimming method can control the illumination error within 5lux,and the dimming is accurate.The dynamic dimming method can save energy and alleviate worker fatigue at the same time.
