A fluorescent lamp having multiple zones with different ultraviolet radiation characteristics along its length has a tube with a first fluorescent coating for producing ultraviolet radiation of substantially uniform intensity extending over a first finite length of the tube adjacent one end. A second fluorescent coating extending over a second finite length of the tube adjacent its other end thereof produces ultraviolet radiation of a substantially uniform intensity and having radiation characteristics which are different from those produced in the first finite length. Generally, the UVB intensity and UVB/UVA ratio will be increased. This lamp is ideally suited for use in tanning chambers to provide uniform tanning by providing a higher intensity and a higher UVB/UVA ratio for radiation in the area of the head.
A fluorescent lamp having multiple zones with different ultraviolet radiation characteristics along its length comprising:
A fluorescent tanning lamp having multiple zones with different ultraviolet characteristics along its length comprising:
A fluorescent tanning lamp assembly for a tanning chamber comprising an array of a multiplicity of parallel spaced elongated lamps having multiple zones with different ultraviolet characteristics of radiation along their length and each comprising:
The fluorescent tanning lamp assembly in accordance with 10 wherein said second finite length is about 8-18 inches.
The fluorescent tanning lamp assembly in accordance with 10 wherein said fluorescent coatings comprise mixtures of fluorescent coating materials in which the proportions are varied to produce the variation in radiation characteristics.
