Summary
[edit]
| Description |
Français : "Pont Napoléon", qui enjambe une section canalisée de la rivière Moyenne-Deûle à Lille, près de la Citadelle Vauban de Lille. Photo prise quelques jours après la fin de la restauration 2014-2015) et de la pose d'un nouvel éclairage (janvier 2015).
Cet éclairage est "basse consommation". Il est aussi conçu pour ne pas éblouir les personnes et ne contribuer aussi peu que possible à la pollution lumineuse : les lampes sont des Leds blanches intégrées dans la rampe centrale, et des Leds jaune éclairent les éléments architecturaux. L'éclairage est néanmoins permanent (sans détecteur de présence). La longueur d'onde est choisie pour avoir un effet minimal sur les papillons nocturnes et donc les chiroptères, et la position des lampes est étudiée pour que la lumière ne soit pas dirigée vers la rivière traversée par ce pont (la Moyenne-Deûle), afin de ne pas interférer avec les cycles nyctéméraux du plancton ou des poissons. English: "Napoleon Bridge" that spans a canalised section of Middle River Deûle in Lille, near the Vauban Citadel. Photo taken a few days after the end of the 2014-2015 restoration) and installation of new lighting (January 2015). This lighting is "energy saving". It is also designed not to dazzle people and contribute as little as possible to light pollution: the lights are white LEDs integrated in the central ramp, and yellow LEDs illuminate architectural elements. Lighting is still standing (without presence detector). The wavelength is chosen to have a minimal effect on moths and therefore bats, and the position of the lamps is designed so that the light is not directed towards the river crossed by the bridge (the Mid-Deûle) in order not to interfere with the rings nyctéméraux plankton or fish.. |
