Abstract

Lampe comportant un tube à décharge dont la longueur nominale est de 60 à 150 cm et qui consomme en régime une puissance nominale de 0,25 à 0,50 watt/cm. Le tube est muni d'une couche luminescente contenant au moins un aluminate luminescent présentant la structure cristalline hexagonale, qui est liée à la structure des ferrites hexagonales. Le tube présente un diamètre externe de 20 à 28 mm. Application : éclairage.Lamp comprising a discharge tube the nominal length of which is 60 to 150 cm and which consumes a nominal power of 0.25 to 0.50 watt / cm under operating conditions. The tube is provided with a luminescent layer containing at least one luminescent aluminate having the hexagonal crystal structure, which is bonded to the structure of the hexagonal ferrites. The tube has an external diameter of 20 to 28 mm. Application: lighting.
