Introduction - IOHNIC

Introduction

IOHNIC is a new luminaire concept created and patented by Sacyr Concesiones. It eliminates the problems of uniformity, glare, and visibility in tunnels, improving traffic safety. This technology combines the highest quality standards with energy efficiency, innovation, and sustainability benefits. 

 

 

 

 

Main features

The system provides 100% longitudinal uniformity and overall uniformity close to 100%. IOHNIC also eliminates the flickering effect produced by conventional lighting systems made up of independent light points. 

At the same time, the installation’s continuity allows the use of tightly closed optics that direct the light beams onto the road and not into the driver's eyes, avoiding glare.

These glare and uniformity advantages improve the sensitivity of the human eye by more than 30% compared to other solutions, so that obstacles can be perceived earlier. This also improves the comfort, safety, and appearance of the tunnels where it is installed.

IOHNIC is made up of more than 500 different luminaires ranging from 6 to 320 watts per LED module. This allows the luminaire to adapt perfectly to the International Commission on Illumination requirements (CIE).  In this way, it avoids the typical staggering of the conventional reinforcement lighting at the tunnel entrances.

The continuity and linearity of our solution generates an effect that guides users, making driving easier and more predictable, especially in tunnels with curved layouts.

IOHNIC also significantly increases energy savings due to the lumen per watt efficiency of its luminaires, and thanks to the real-time adaptation of the light flux to external luminance and traffic.
