【摘要】 基于照明节能减排考虑,文章依托某高速公路隧道,应用了一种采用自然光对隧道入口段进行照明的技术方案;通过特殊设计的采光带将自然光引入隧道入口段,并参照国际惯用的人眼视觉"适应曲线",对自然光照明亮度曲线进行模拟与拟合,使其达到了完全取消入口段加强照明的目标;为了验证方案的实用性和可靠性,借助试验手段对隧道照明指标,如亮度、均匀度及亮度变化历程等进行了评价。研究结果表明,自然光照明方案设计指标满足工程要求;与"传统灯具照明"方案相比,该方案具有基本消除入口"黑洞效应"、增强隧道内行车安全性和舒适性、节能减排、简单实用、成本合理等特点。更多还原

【Abstract】 On account of saving energy and reducing emissions, an innovative lighting proposal is introduced in which natural light is used for illumination at an expressway tunnel entrance. The natural light is brought into the tunnel entrance by a specially designed daylighting band, and the luminance curve of the natural light is modeled and fitted to the current international human visual adaptation curve, thereby eliminating the need for enhanced lighting measures at the entrance. To verify the practicability and reliability of this scheme, the indexes of tunnel lighting like luminance, uniformity of luminance, evolution of luminance, and so on are evaluated by an experimental approach. The results show that the design index of the natural-light illumination scheme meets engineering requirements; compared with the conventional lamp lighting scheme, it basically eliminates the "black-hole effect" at the entrance and enhances tunnel traffic safety and comfort with the added advantages of saving energy and reducing emissions while being simple, useful, and cost-effective.更多还原
