The Rotterdamsebaan opened on the 5th of februari.

The new road connection Rotterdamsebaan connects the highways (A4 / A13) and the central ring of The Hague and makes the region more accessible. The traffic to and from the motorways can thus be distributed better and the congestion on the Utrechtsebaan is less.

The 4 kilometre long road connection has a 1800-meter-long tunnel and a 450-meter-long sunken roadway with several underpasses. The drilled tunnel consists of two tubes with an internal diameter of ten meters. Each tube has 2 lanes. The tunnel is drilled underneath a residential area, a park and a canal.

The Rotterdamsebaan project is a prime example of sustainable infrastructure in the Netherlands. The tunnel has many sustainable applications such as solar panels, LEAB asphalt, sound converters, LED lighting, and so on. It is one of the largest tunnels in the Benelux and the longest tunnel that is equipped with BB Lightpipe lighting. The tunnel has a high architectural value, partly thanks to the lighting from BB Lightpipe.

The tunnel is called the Victory Boogie Woogie Tunnel, named after the famous unfinished painting by the Dutch painter Piet Mondriaan.

Both the tunnel and the sunken location have a continuous BB Lightpipe light line on both sides at a height of 4,7 meters. The lightpipe lengths are custom made to the white curved wall elements, which ensures a sublime result. This appearance ensures a comfortable and safe passage for the road user.

Bennie Elfrink of BB Lightpipe took care of the development of our innovative lighting solution. Paul de Graaf successfully completed the light calculations and project coordination between our factory, the system integrator and the installation company.

Lighting equipement

The tunnel is equipped with 2.091 lightpipes, in lengths of 1,25 - 2,5 - 3,75 and 5 meters. The lengths are adjusted to the dimensions of the wall sections. A total of 1,461 external driver housings are installed, part of which controls 2 lightpipes. The light colour is set to 3500K, at the special request of the customer, which gives a warmer tone than the standard 5000K.

The lightpipes are placed at an angle of 35 ° for optimal light distribution. The specially designed suspension bracket connect the lightpipe to the wall construction. The bracket is developed by Cruxin within the TKH Group. Cruxin also acted as a system integrator for lighting and lighting controls.

The customer now has high-quality lighting with a long life span and very low maintenance for a period of at least 15 years.

BB Lightpipe illuminates the Dehin tunnel in Liège

The lighting in Dehin Tunnel in Liège, Belgium, was recently fully renovated. While the existing fixtures where mounted as a point lighting above the driveway, the new BB Lightpipes are mounted in a continues line at the side. This improves driving comfort and road safety in the curved and sloped tunnel.

For the same reason light level is adjusted automaticly to the wheather type outside. The different lighting scenes can switch in several steps from very sunny to very cloudy, as well as to a night level. This way visability for the driver is optimized while reducing glare to a minimum.


Tunnel specific lighting

Lighting for tunnels and underpasses are in many ways different from traditional LED fixtures for indoor lighting. For tunnels there are very specific requirements for material usage, electrical safety and lighting demands.

To meet the requirements from the CIE norms (L20 entrance lighting curve) BB Lightpipe developed the High Lumen Output Lightpipe (HLO). This fixture is very suited for entrance- and exit zone lighting in tunnels. The HLO is DALI dimmable as is used in the lighting scenes. The high fixture efficiency in combination with the adjustable lighting levels optimize energy consumption. Therefore the BB Lightpipe has a mayor energy cost reduction in comparison to traditional tunnel lighting fixtures.

The BB Lightpipe is a high quality fixture thanks to the use of ceramic LED’s in combination with a good termal conduction. Therefor the LED stays cool and the lumen depreciation is low. Replacement of the LEDs is no longer needed which means maintenance cost is kept low. This is an impotant factor in tunnels where lighting is difficult to reach and road closure is expensive. The BB Lightpipe can be implanted in new and existing projects.

When you choose for the BB Lightpipe you are ensured of a sturdy and durable fixture in combination with high aesthetic qualities and low energy consumption. The BB Lightpipe fixtures are impact resisitant IK10+ and IP66 water tight. This means the fixtures can be mounted in harsh envoirement such as tunnels and underpasses.

Unique features of the BB Lightpipe HLO

Continues, optical and modulair lighting system with:

+ vandal proof polycarbonate tubes with prism foil technology;

+ sturdy anodised aluminium profile and housing;

+ 4 led-modules, with 18 ceramic LEDs each;

This makes;

+ a constant, uniform and glare free lighting distribution;

+ a 180 degree light output increasing comfort;

+ a high lumen output for high light demands;

+ suitable for entrance and exit zones;

+ energy savings by making use of dimming (DALI);

+ possibility of integrating emergency lighting or Evaq;

Dehin tunnel 2

A BB Lightpipe installation is mounted in the Stuvsta tunnel in Stuvsta, Sweden.

The installation in the Stuvsta tunnel from 1994 is renovated and a new lighting system is implemented.

The lighting installation consist of a continues light line and additional 'high lumen output' lighting at both entrances of the tunnel.

The continuous light line give users a comfortable passage of the 193m long tunnel without any annoying flickering effects.  The enhanced entrance light level is to offer the traffic a safe transition to the darker tunnel area.

A L20 camera is used to control the lighting in several stages. When the sun is most powerful, all lights are on. When the weather is more cloudy the light is dimmed. At night the entrance lighting is turned of and the basic lighting is dimmed. At night the lighting still forms a continues line but dimmed to a lower light level, so at night there’s also annoying flickering.

The customer choose for the BB Lightpipe because of the long lifetime and therefore low maintenance. Also the system is very easy to install.

Three years after installation it’s time for the first maintenance interval in the Derivation tunnel in Liege.

In just three hours all 180 fixtures are cleaned and inspected for defects or flaws. A hard brush is used to remove spider webs. Water with some cleaning solution and a soft cloth where used to clean the tube from any dirt produced by exhaust pollution. No further problems were detected.

Also a light measurement has been executed to check the light depreciation. There was no noticeable aging of the LED’s detected, therefore there was no need to adjust the lumen output at this time.

The Derivation tunnel is a project of Techno Specials, the sales organisation of the BB LEDlightpipe in Belgium.
