RADIATION APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus for producing ultraviolet radiation, particularly a quick-tanning sunlamp, the apparatus has a source of substantially uniform ultraviolet radiation, including at least two closely adjacent tubular low-pressure mercury lamps; an arrangement for intercepting at least the major percentage of wavelength bands of ultraviolet radiation below approximately 315 mm; and reflector system cooperating with said source and defining at least one opening for the escape of ultraviolet radiation consisting essentially of the remaining wavelength band of ultra- violet radiation, said reflector system including for each of said lamps a trough-shaped reflector surrounding the lamp along an arc, and said reflector system including at least one intermediate portion between adjacent ones of said lamps and two lateral portions having parts which project forwardly of said intermediate portion and have forward edge portions defining said opening, the space be- tween said lateral portions and forwardly of said inter- mediate portion being substantially unobstructed, and the source and reflector system cooperating to establish in the vicinity of the opening a high-density radiation field, the heat output of said lamps being sufficiently low so that the temperature in the region of said radiation field is below the range of discomfort of a person exposed to the field.
