Abstract:
Disclosed are discharge lamps that stimulate the production of vitamin D in a person exposed thereto, and more specifically, to discharge lamps which over a predetermine exposure period stimulate a person's production of vitamin D without causing significant facultative pigmentation or melanin oxidization. Moreover, the present invention is also directed to discharge lamps that in addition to stimulating a person's production of vitamin D, emit photons that rejuvenate the collagen/elastin matrix that supports the person's skin, cartilage and bone.

Abstract:
Disclosed are discharge lamps for use in tanning applications and methods of making the same. The lamps include, among other elements, an elongated vitreous tube which has an outer periphery and axially opposed first and second ends that define an axial length for the tube. A coating is applied on the interior of the tube for emitting ultraviolet radiation in tanning wavelengths when a voltage to the lamp. The coating is specifically formulated so that the ultraviolet radiation emitted from the lamp in a range of about 320 nm to about 340 nm is less than or equal to about 10 percent of the ultraviolet radiation emitted from the lamp in a range of about 280 nm to about 400 nm.
