Abstract:
(EN) The present invention relates to a fluorescent lamp, in particular, to a fluorescent lamp improved in starting characteristics in the dark. A fluorescent lamp has a glass bulb (101) having a discharge space inside thereof, external electrodes (102, 103) are formed in both end portions of the bulb, and a phosphor layer (106) is formed on the inner surface of the glass bulb. The glass bulb is formed of a glass having a sodium oxide content of 3 to 20 %. The phosphor layer contains phosphor particles (106R, 106G) containing no alumina and phosphor particles (106B) containing alumina. A metal oxide (107) is attached to the surface of the phosphor particles containing alumina. The sodium oxide precipitated on the inner surface of the above glass bulb improves starting characteristics in the dark. The phosphor particles containing alumina are protected by the metal oxide, since they are susceptible to the deterioration by the reaction with sodium oxide.
(FR) La présente invention concerne une lampe fluorescente, en particulier, une lampe fluorescente aux caractéristiques de démarrage améliorées dans le noir. Une lampe fluorescente comporte une ampoule de verre (101) ayant un espace de décharge à l’intérieur de celle-ci, des électrodes externes (102, 103) sont formées dans les deux portions d’extrémité de l’ampoule, et une couche de phosphore (106) est formée sur la surface interne de l’ampoule de verre. L’ampoule de verre est formée d’un verre ayant une teneur en oxyde de sodium comprise entre 3 et 20 %. La couche de phosphore contient des particules de phosphore (106R, 106G) sans alumine et des particules de phosphore (106B) contenant de l’alumine. Un oxyde de métal (107) est fixé à la surface des particules de phosphore contenant de l’alumine. L’oxyde de sodium précipité sur la surface interne de l’ampoule de verre ci-dessus augmente les caractéristiques de démarrage dans le noir. Les particules de phosphore contenant de l’alumine sont protégées par l’oxyde de métal dans la mesure où elles sont susceptibles de se détériorer du fait de la réaction avec l’oxyde de sodium.
