Patent
CA 2226604
A neon lamp providing white light is disclosed. The lamp is operated to stimulate the neon to emit both ultraviolet light, and visible red light. A phosphor coating responsive to the ultraviolet light produces a complementary green blue light that in combination with the neon red light yields a white light. The lamp is small, efficient, and not subject to the effects of cold that cause mercury based fluorescent lamps to operate poor in cold conditions typical of out of door operation.
La présente invention a pour objet une lampe au néon produisant une lumière blanche. La lampe en question stimule l'émission de lumière ultraviolette et de lumière rouge visible par le néon. Une couche fluorescente produit, en réaction à la lumière ultraviolette, une lumière complémentaire vert-bleu qui, combinée à la lumière rouge du néon, se transforme en lumière blanche. De faibles dimensions et efficace, la lampe est non sujette aux effets du froid, qui est une cause reconnue du mauvais fonctionnement des lampes fluorescentes à vapeur de mercure utilisées à l'extérieur.
