Good contrast in daylight, automatic reduction of brightness at dark, color fidelity that is adapted to the red and green tones conventionally used for traffic signs, and high flexibility through multiple nested symbols characterize this solution. Given the increased requirement for outdoor use (temperature, humidity, dust), reliable and good product design pays for itself.
Reliability and durability of an LED are of special importance when it comes to tunnel lighting. In these cases, LED lighting can provide illumination that is not too harsh on the eye through good design, flexibility of the CTI, and color temperature. Reliability is important for the operator, as a tunnel cannot be closed to replace a light.
The use of LED technology for street lighting often consists of replacing existing lighting solutions. Essential factors include energy efficiency, high quality of light and durability of LED solutions.
In contrast to tunnel lights, there is a wide variety of forms for the light fixture that often also influence the overall appearance of the surroundings. Therefore, flexible solutions are necessary that require adapting the electric/thermal interior of the light to the existing outside geometry. It is equally important that the LED lights react correctly to being turned down for the night through local transformer without changing the wiring between lights.
