Disclosed is a new and useful discharge lamp for use in applications, such as tanning and technical lighting, and a method of making the same. The discharge lamp includes, inter alia, a vitreous tube (52) having an axial length, a base phosphor coating (56) applied on the interior of the tube along the entire axial length, and at least one phosphor over-coat (59) applied over the base phosphor coating (56) in one or more axial regions of the vitreous tube. The phosphor over-coat is applied to less than the total length of the vitreous tube. In a representative embodiment, the vitreous tube has an outer periphery which is smooth, but in alternate embodiments, a helical groove path is formed therein over at least a portion of the axial length.

L'invention concerne une lampe à décharge nouvelle et utile à utiliser dans des applications, telles que le bronzage et l'éclairage technique, ainsi que son procédé de fabrication. Ladite lampe à décharge comprend, entre autres, un tube vitreux (52) possédant une certaine longueur axiale, une couche de base de phosphore (56) appliquée sur l'intérieur du tube, sur l'intégralité de la longueur axiale, et au moins une surcouche de phosphore (59) appliquée sur la couche de base de phosphore (56) dans une ou plusieurs zones axiales du tube vitreux. La surcouche de phosphore est appliquée sur moins de la longueur axiale totale du tube vitreux. Dans un mode de réalisation représentatif, le tube vitreux possède une périphérie extérieure lisse, mais dans d'autres modes de réalisation, un chemin se présentant sous forme de rainure hélicoïdale est formé dans ledit tube, sur au moins une partie de la longueur axiale.
