Abstract

Lampe présentant une efficacité plus grande pour un même rendu des couleurs que les lampes fluorescentes du type de luxe. Elle comprend un revêtement fluorescent qui est une combinaison de 68 à 85 % en poids d'un composé fluorescent d'haloapatite de strontium et de 32 à 15 % en poids d'un composé fluorescent d'oxyde d'yttrium activé à l'europium. Application aux lampes à vapeur de mercure basse pression.Lamp with greater efficiency for the same color rendering than luxury type fluorescent lamps. It comprises a fluorescent coating which is a combination of 68 to 85% by weight of a fluorescent compound of strontium haloapatite and 32 to 15% by weight of a fluorescent compound of europium activated yttrium oxide. . Application to low pressure mercury vapor lamps.
