Title (EN) FLUORESCENT LAMP AND BACKLIGHT UNIT
(FR) LAMPE FLUORESCENTE ET UNITE DE RETROECLAIRAGE
Abstract: front page image
(EN)A fluorescent lamp (20) includes a glass bulb (30) that has mercury enclosed therein, and a phosphor layer (32) formed on an inner side of the glass bulb (30). The phosphor layer (32) includes three types of phosphor particles, which are red phosphor particles (32R), green phosphor particles (32G) and blue phosphor particles (32B) that are excited by ultraviolet radiation to emit red light, green light and blue light respectively. The blue phosphor particles (32B) and green phosphor particles (32G) have a property of absorbing ultraviolet radiation with a wavelength of 313 nm.
(FR)La présente invention a trait à une lampe fluorescente (20) comportant une ampoule en verre (30) renfermant du mercure, et une couche de phosphore (32) formée sur une face intérieure de l'ampoule en verre (30). La couche de phosphore (32) comprend trois types de particules de phosphore, qui sont des particules de phosphore rouges (32R), des particules de phosphore vertes (32G), et des particules de phosphore bleues (32B) qui sont excitées par un rayonnement ultraviolet pour émettre une lumière rouge, une lumière verte et une lumière bleue respectivement. Les particules de phosphore bleues (32B) et les particules de phosphore vertes (32G) présentent une propriété d'absorption de rayonnement ultraviolet avec une longueur d'onde de 313 nm.
