Abstract:
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.
