The Vlake tunnel, located in Zeeland, Holland, has employed LED luminaires technology since June from the company Indal. This is the first time that this type of luminaire has been used for the continuous lighting of a tunnel roadway in Europe.
The use of LED luminaires for linear illumination systems in tunnels is something completely new. This type of lighting offers numerous advantages over using separated LEDs, which place each light at a certain distance from the next. The main disadvantage of this point lighting is the flickering effect, which can confuse drivers. Indal’s T-line luminaires form a continuous line of clear, white light that is much more efficient and comfortable for users of the motorway.
Among the many advantages of using this technology is its improved energy efficiency: Indal’s luminaires have an expected useful life of 15 years, which translates into maintenance cost savings. Its long life is possible thanks to the COO-LED cooling system, patented by the company. Another characteristic that results in lower energy consumption and improved visual comfort is that the lights can be dimmed and adjusted automatically, in order to provide the required level of lighting in the tunnel at any time during the day. Finally, the DIRECTA lens system from the company improves directionality and reduces light loss.
