Title
(EN) FLUSH LIGHTING SYSTEM FOR CLEANROOM
(FR) SYSTEME D'ECLAIRAGE ENCASTRE POUR SALLES BLANCHES
Abstract
(EN)
A flush lighting system for cleanroom environments encompassing a modular ceiling design includes a light well housing (10), filter packs (22, 34) above and adjacent to the light well housing (10), and a lock apparatus (40) to seal the various light well housings (10) and filter packs (22, 34). By utilizing such a design, filtered air flows uniformly downward across the entire area of the ceiling without creating dead air channels underneath the light wells.
(FR)
L'invention concerne un système d'éclairage encastré pour salles blanches. Ce système comprend une conception de plafond modulaire comprenant un carter du puits d'éclairage (10), des ensembles filtres (22, 34) disposés au-dessus et de manière adjacente au carter du puits d'éclairage (10), et un appareil de verrouillage (40) pour assurer la fermeture étanche des divers carters (10) et ensembles filtres (22, 34). Cette conception permet d'obtenir un écoulement d'air filtré vers le bas sensiblement uniforme sur la totalité du plafond sans créer d'espace mort sous les puits d'éclairage.
