近几年隧道LED照明灯具以其启动快、能耗低、光色可控性好等优势已广泛应用在隧道照明工程中。但目前隧道LED照明灯具大都采用光亮度单一调光控制功能,没有充分发挥隧道LED照明灯具光亮度和光色温双指标可控技术优势,更没有考虑LED光源色温和光谱分布对隧道LED照明光环境安全性和舒适性的影响。因此,本文研究了隧道LED照明光源色温与视认舒适性和视认距离的关系,分析了LED光源色温对隧道照明光环境的实际影响,提出了适用于隧道LED照明入口段和出口段光环境色温指标,为打造安全型和舒适型“两型”隧道LED照明光环境提供理论依据。
In recent years, tunnel LED lighting with its fast start, low energy consumption, light color controllable and other advantages have been widely used in tunnel lighting projects. However, most of the current tunnel LED lighting uses a single brightness dimming control function, did not give full play to the tunnel LED lighting and light color temperature dual index controllable technology advantages, but did not consider the LED light source color temperature and spectral distribution of the tunnel LED lighting environmental safety The impact of sexual and comfort. Therefore, this paper studies the relationship between the color temperature of the tunnel LED lighting source and the perceived comfort and apparent distance, and analyzes the actual influence of the color temperature of the LED light source on the lighting environment of the tunnel, and puts forward the practical application of the LED lighting entrance and exit section light environment Color temperature indicators, to create a safe and comfortable “two types ” tunnel LED lighting environment provides a theoretical basis.
