Safely Through the Tunnel With Siteco
Light Means Safety, Light Creates Well-Being.
Tunnels and underpasses present the highest demands upon lighting and safety. During daytime, danger levels are at their highest. As well as traffic safety, a steady flow of traffic in tunnels and underpasses is important.
When the level of lighting quality increases the well-being of drivers increases, resulting in more traffic safety, more driving pleasure, constant driving speeds and a harmonious traffic flow. Emergency exits, emergency call sites and escape exits are equipped with permanent emergency luminaires. With pedestrian tunnels or pedestrian underpasses the factor of general safety must also be considered.
Modern Lighting Technology
Tunnel lighting must have the ability to adapt itself to the eye and the abrupt transition from light to dark. This occurs with a very high level of illuminance within the tunnel in the portal (tunnel entrance) area. In order to eliminate the uncomfortable feeling of enclosed spaces, the illumination levels within tunnels are somewhat higher than with street lighting for open roads. Lateral continuous rows give a homogenous light distribution and avoid flickering effects as drivers travel through. They also create a directional optical effect. Highly efficient reflector systems cover all types of tunnel lighting.
The Siteco plus: standardised glare reduction and an optimal utilisation factor.
At the present time, modern tunnel luminaires with high pressure sodium lamps create the best viewing conditions. High levels of exhaust fumes and extreme fluctuations in temperature and dampness demand a robust luminaire construction. Siteco tunnel luminaires are equipped with highly effective, high-precision reflectors for high pressure and fluorescent lamping. According to the type of lamp, luminaire housing is of stainless steel or cast aluminium. Stainless steel housings have the advantage that they are unbeatable in respect to corrosion resistance and service life. Safety glass enclosures and additional surface treatments heighten the protection against corrosion for many years. Protection ratings of IP65 and IP67 and IK 09 and IK 10 are required for protection against foreign matters and mechanical impact. Simple maintenance, easy relamping and handling without tools are further proof of Siteco quality.
Use of Economic Resources
Tubular, compact fluorescent lamps and the use of dimmable electronic control gear all help to reduce energy. They result in an optimal lighting quality with at least the same level of illuminance, and decrease energy use by up to 50%.
Tried And Tested Worldwide
Siteco tunnel luminaires increase safety and well-being in numerous tunnels and underpasses. The fourth Elbe tunnel duct as well as many tunnels in the alpine regions benefit from Siteco technology.
