Tunnel Guidance

                                           For Tunnels: 

•	LEDline® is Used for traffic guidance;

•	it can be used for Tunnel lighting;

•	to improve tunnel safety in the event of             fire and smoke;

•	to control tunnel traffic speeds.

since 2009, LEDline® has been Used for 
traffic safety guidance lighting
at the Bjørvika Tunnel in Oslo, Norway

In 2009, LEDline® safety guidance lighting was installed in the ceiling of the Bjørvika Tunnel in Oslo, Norway. It is still functioning today. Each yellow LEDline® unit was installed next to the standard white tunnel lights, along with the entire spare tunnel ceiling. Its brightness outside and within the tunnel clearly demonstrates LEDline®'s safety guidance lighting ability to provide functional lighting levels in tunnels. 
Used as ceiling guidance, when the usual tunnel is blocked, sequencing lit LEDline® safety guidance units are used to guide traffic to an alternate tunnel. Therefore, as an emergency safety guidance lighting for drivers and vehicles, if there is an accident or other blockage of the tunnel and there is a requirement to change to the other clear tunnel, the LEDline® safety guidance lighting, would illustrate this by leading the traffic from the blocked tunnel to the open alternate tunnel next door. 
Every LEDline® safety guidance unit there has 12 x LEDs, is VDC powered by HIL-Tech's VDC power supply, and is individually computer-controlled with HIL-Tech's "Dynamic Effects Package".  
The units are controllable as to; the dimming of any individual unit to any level of brightness; having all units on, or some units on and others off; and of being able to sequence the LEDline® safety guidance units in any direction with any number or combination of LEDline® guidance units. 

Visible in daylight, yellow, 12 x LED LEDline® units, were installed next to Bjørvika Tunnel standard tunnel lighting.
 (Note: As demonstrated below in the video, even though the white tunnel lighting is left on, the yellow LEDline® guidance lighting is brighter and shows up better in the tunnel).

Below is a Video of the LEDline® Ceiling safety Traffic Guidance System in the Bjørvika Tunnel. 

With HIL-Tech's "Dynamic Effects Package", each LEDline® guidance unit is independently computer controllable as; to dimming; to the number of lit units on at any one time; and to the sequencing direction of the lit units, so when the main tunnel is blocked, operators can remotely sequence the LEDline® safety guidance units, leading drivers safely away towards the available alternate tunnel. 

LEDline® could be used in Tunnels;

•	for tunnel lighting;

•	in the event of a fire and or smoke                 with difficult visibility: sequencing              LEDline® could improve tunnel safety         by leading people/drivers away from           the fire and smoke, towards the exit;
 
•	to control tunnel speed or speeding:           Those passing, or not keeping pace                  with "the remotely set speed" of the              sequencing LEDline® safety guidance           units, could be automatically                            ticketed.

How and why LEDline® could be used 
for tunnel lighting.

A Single LEDline® Safety Guidance Unit Produces Some 1400 Lumens of Fully Useable Directed White Light,  (Normally 6500K unless otherwise specified).  In addition, a LEDline® Lamp, Including Its Mounting Plate, is only 28.5mm (1.1") high, therefore; 
•	in older tunnels, it could be easily fitted into the tunnel on the roof or at the sides of the tunnel; 
•	each LEDline® safety guidance unit produces some 1400 lumens of fully useable directed light, therefore,                  spaced together, would provide any required lighting levels; •	being solid, so hermetically sealed, the LEDline® lighting system can be rapidly cleaned with very                         
        high-pressure water hoses, saving cleaning and any tunnel downtime. (Whilst driving through a tunnel,                      pressure washing and cleaning the lighting fixtures, the higher the water pressure, the faster the lighting                   units can be cleaned, reducing any necessary tunnel lane closure times. LEDline® safety guidance lighting                 being completely solid, means that operators do not need to worry about the pressure washing water entering          the light's electronics causing their subsequent corrosion and early maintenance;•      if  the LEDline® was powered via the completely sealed induction power supply system, this would again                    eliminate any concerns about the water pressure cleaning, causing electrical corrosion;•     if additional capabilities for the LEDline® was desired, HIL-Tech’s VDC powered system and its 
       "Dynamic Effects Package" could be  used to power the LEDline® and remote computer control of each                         LEDline® unit for dimming and/or sequencing could be used to; •	sequence LEDline® units, leading pedestrians and the walking drivers safely, away from any  fire and smoke;•      control sequencing lights as to their speed, those overtaking the ceiling lights, could be automatically                         ticketed;
•	guide, and sheppard people towards tunnel escape areas;
•	outline any escape exits with green LEDline®.
