DescriptionModèle de luminaire pour réduire la pollution lumineuse.jpg |
Français : modèle de luminaire garni d'un bafflage interne spécial, protégeant mieux l'environnement nocturne, en orientant la lumière plus verticalement vers le sol, et limitant l'éblouissement en périphérie du luminaire ; pour les hommes, et pour la faune qui peut y être sensible (papillons, oieaux et chauve-souris ou autres animaux nocturnes).
Ce luminaire limite le halo qui contribue à la pollution lumineuse. Le spectres jaune de la lumière est également réputé moins perturbant pour la faune. Lieu : «Parc boisé de la Citadelle», ville de Lille, le nord de la France. English: Model of tlight designed for better protection of nocturnal environment, lighting is trimmed with an internal special bafflage guiding light more vertically to the ground and minimizing glare on the outskirts of luminaire (for men, and for wildlife, which may be sensitive , as butterflies, birds and bat or other nocturnal animals).
