    摘要: A fluorescent lamp (10) having multiple discrete zones with different levels of radiation intensity along its length has a tube (12) with a fluorescent coating (20) on the interior of the tube (12) adapted to produce ultraviolet radiation of substantially uniform intensity. A reflective coating (18) is provided along a finite length of the tube adjacent one end thereof and about only a portion of the circumference thereof to provide an increased intensity of radiation emanating from the uncoated portion of the periphery of the lamp in the finite portion due to reflection of radiation from the reflective coating. This lamp is especially useful in an array for a tanning chamber to provide a higher intensity of ultraviolet radiation in the facial area.
