An improved efficiency fluorescent lighting system is described. The system utilizes reduced rows of fluorescent luminaires which are spaced much further apart than traditional spacing. The luminaires used in the system of the present invention have increased light output of each luminaire by up to fifty percent through a combination of use of a high efficiency lamp producing about 3250 lumens, an electronic dimming ballast having a ballast factor of about 1.2 and a luminaire having a spacing to mounting height ratio of at least 1.5.
La présente concerne un système d'éclairage fluorescent à efficacité accrue. Le système fait appel à un nombre réduit de rangées de lampes fluorescentes, disposées et espacées à intervalles beaucoup plus grands que la normale. Chaque lampe fluorescente de cette invention offre un meilleur éclairage, soit une amélioration qui peut atteindre 50 p. 100, grâce à l'utilisation conjointe d'un tube à grande efficacité qui produit environ 3 250 lumens, d'un ballast de gradation dont le facteur de ballast est d'environ 1,2, et d'un dispositif d'éclairage qui a un rapport d'espacement et de hauteur de fixation d'au moins 1,5.
