Sacyr IOHNIC, the tunnel lighting system of the future

Sacyr IOHNIC is a linear tunnel lighting system, mostly bilateral, which allows maximum savings in electricity consumption and 100% uniformity of light.


At Sacyr, through our subsidiary Sacyr Concesiones, we have developed a patent for tunnel lighting using continuous LED strips to improve lighting in road tunnels and ensure the safety and comfort of road users. Thanks to the implementation of this technology, we can reduce electricity consumption by 66%, which means a reduction of 153 tons of CO2 per year, obtain 100% lighting homogeneity and regulate the equipment freely. 

This project presents an innovative tunnel lighting system based on LED technologies that has its field of application on the user and tends to respond not only to environmental issues, but also has a positive effect on citizens, ensuring their safety and improving their quality of life. 
The implementation of this pioneering solution has great advantages for the user in terms of safety and comfort. Thus, the system facilitates the adaptation to the pupil dilation rhythm, eliminates the flickering effect inside and allows to increase the light intensity.
