Lighting on/off control is the most crucial method of interior lighting control, with numerous automated and intelligent on/off control strategies being researched and developed. Currently, these strategies are primarily aimed at energy savings rather than creating a satisfactory optical environment. This paper introduces a novel on/off control method based on the subset sum model, primarily aimed at creating lighting environments that meet functional or user needs while also achieving energy efficiency. The implementation approach used enhanced optimization algorithms to select the optimal combination of luminaires for the on/off scheme, ensuring that different functional areas achieve the desired lighting effects. To ensure effective lighting control, an approach is studied to determine luminaire number, specifications, and arrangement based on the desired lighting effect, in lighting design process. The proposed lighting control and design methods together form a comprehensive lighting control system with practical application value. Considering its diverse potential application, three typical scenarios were evaluated: multifunctional interior space lighting, localized general lighting, and energy-saving lighting considering daylight. The experimental results from the three scenarios demonstrate that the lighting on/off control method based on the subset sum model achieves comparable illuminance levels, uniformity, and energy efficiency compared to the LED dimming-based method. This approach delivers excellent lighting quality and energy savings in various public building environments and demonstrates superior practical value.

用于室内照明系统的子集和模型以及相应的照明开/关控制方法



照明开/关控制是室内照明控制的最关键方法,许多自动化和智能的开/关控制策略正在研究和开发中。目前,这些策略主要旨在节省能源,而不是创造令人满意的光学环境。本文介绍了一种基于子集和模型的新型开/关控制方法,主要旨在创建满足功能或用户需求的照明环境,同时实现能源效率。该实施方法使用增强的优化算法为开/关方案选择最佳的灯具组合,确保不同的功能区域实现所需的照明效果。为了确保有效的照明控制,在照明设计过程中,研究了一种根据所需照明效果确定灯具数量、规格和布置的方法。所提出的照明控制和设计方法共同构成了一个具有实际应用价值的综合照明控制系统。考虑到其多样化的潜在应用,评估了三种典型场景:多功能室内空间照明、局部通用照明和考虑日光的节能照明。这三种情景的实验结果表明,与基于 LED 调光的方法相比,基于子集和模型的照明开/关控制方法实现了相当的照度水平、均匀性和能源效率。这种方法在各种公共建筑环境中提供了出色的照明质量和节能效果,并显示出卓越的实用价值。
