| ===== Operation ===== | ===== Operation ===== | ||
| + | The requirements for tunnel lighting are determined by the nature of the human eye. The tunnel lighting must be controlled such that users, both during the day and by night, can approach, pass through and exit the tunnel without changing direction or speed with a degree of safety equal to that on the approach road. Especially at daytime the human eye can only adapt slowly to the lower lighting levels in the tunnel. The lighting in the access zone has to be controlled such that drivers can perceive obstacles in the tunnel on time to stop. At night time it is sufficient to provide lighting levels in the tunnel at least equal to those outside the tunnel. | ||
| + | Several international and national guidelines and standard describe how to design and control tunnel lighting. | ||
| + | The Austrian RVS for instance describes a reduction of the lighting level in the interior zone based on illuminance levels that prevail in front of the portal. | ||
| - | ===== Advantanges ===== | + | The sensor measures the illuminance hemispheric. The measured value describes the luminous flux which impacts on the transparent hemisphere of the sensor. |

| + | Tunnels are important infrastructure elements in road networks and facilitate the connection of regions. | ||
| + | |||
| + | Environmental conditions in tunnels are influenced by fog, particles and emissions and need to be monitored to protect people on their passage through the tunnel from danger and impacts on their health. Accidents in tunnels, and particularly fires, can have dramatic consequences and can prove extremely costly in terms of human life, increased congestion, pollution and repair costs. At every time people in the tunnel need to be supplied with breathable air and sufficient visibility. | ||
| + | |||
| + | Since 1990 JES Elektrotechnik GmbH develops, installs and maintains systems to monitor air characteristics and lighting conditions in tunnels. Our systems are robust, durable and resistant against the corrosive atmosphere in a tunnel. They operate reliably and have a high accuracy in measurement. | ||
| + | |||
| + | All systems fulfil the requirements of the EC guideline 2004/54/EC (Minimum safety requirements for tunnels in the trans-European road network) and the more detailed national guidelines and provisions: | ||

| + | * Austria: RVS 09.02 Tunnelausrüstung | ||
| + | * Germany: RABT Richtlinien für die Ausstattung und den Betrieb von Straßentunneln | ||
| + | * Switzerland: | ||
