Abstract

L'invention concerne un détecteur de fumée qui comprend une chambre à fumée comprenant une entrée à travers la fumée peut pénétrer dans la chambre. Cette chambre est équipée de deux source lumineuses, de préférence des DEL, qui émettent une lumière à des fréquences aussi espacées que possible. On utilisera de préférence des DEL bleues et infrarouges, ces dernières comprenant des longueurs d'ondes d'environ 430 nm et 980 nm respectivement. La chambre contient en outre un ou plusieurs dispositifs photosensibles qui reçoivent la lumière diffusée par les particules de fumée présentes dans la chambre. Une barrière entre les sources lumineuses et le dispositif photosensible empêche la lumière de passer en ligne droite des sources lumineuses aux dispositifs photosensibles. L'invention concerne également des formes d'exécution comprenant plus de deux sources lumineuses, plusieurs dispositifs photosensibles et plusieurs chambres à fumée.
