照明非常长的公路隧道意味着高的电能消耗，因为它需要全天适当的照明。特别是在白天，隧道入口和出口区域的照度水平必须高于隧道内部的照度水平;这样，当从外部的高自然照明过渡到隧道内部的照明条件时，驾驶员的眼睛能够适应并安全。然而，这导致了高能量需求。因此，本案例研究调查是否有可能通过运用自动新控制系统来最大限度地减少能源需求，该系统调节人工光源的光通量（保证由法规设定的参数），以适应外部自然光的变化。创新的控制系统必须具有高可靠性水平的特点，以保证在发生停电时不会对驾驶员造成危险，并最大限度地降低维护成本。为了进行这种类型的研究，使用软件DIALux来模拟具有调光系统的隧道（具有以高发光效率为特征的灯），该调光系统由预编程逻辑控制系统（具有高平均故障间隔时间（MTBF）值）调节。所获得的节省使得能够在一段时间内摊销这里建议的解决方案，从经济上讲，这是一个有利的选择。
Lighting very long road tunnels implies a high consumption of electrical energy since it requires a proper illumination during the whole day. In particular, in the daytime, the illuminance levels right at the tunnel entrance threshold and exit zones must be higher than those characterizing the inside of the tunnel; in this way, the eye of the driver is able to adapt and be safe while passing from a high natural illumination of the outside to the lighting conditions characterizing the inside of the tunnel. However this causes a high energy demand. Therefore, this case study investigates whether it is possible to minimize the energy demand through the exertion of an automatic new control system regulating the luminous fluxes of artificial sources (guaranteeing the parameters set by the regulation) with respect to the variation of the natural light characterizing the outside. The innovative control systems must be characterized by high reliability levels in order to guarantee conditions which are not dangerous to the driver if an outage occurs and minimize their maintenance costs. To carry out this type of study, the software DIALux was used to simulate a tunnel with a dimming system (with lamps characterized by a high luminous efficiency) regulated by a pre-programmed logic control system (with high Mean Time Between Failure (MTBF) values). The savings obtained enabled the amortization of the solution here suggested in a time interval that makes it an advantageous choice economically speaking.
