<p>The invention relates to a fluorescent tanning lamp with controlled irradiance which comprises a light-transmitting envelope being transparent for UVA and UVB radiation and intransparent for UVC radiation; means for generating a discharge within the envelope; - a discharge sustaining fill contained in the envelope for emitting short wave ultraviolet rays during lamp operation; a phosphor-containing layer coated on an inner surface of the envelope for converting the shorter wave ultraviolet light (UVC) into longer wave ultraviolet light (UVB, UVA). The coating further comprises an additive for decreasing the output radiation energy of light at least in the UVA spectrum.</p> |
