ABSTRACT:
Apparatus for treatment of psoriasis has a housing with an exit opening located in front of a battery of elongated cylindrical low-pressure mercury lamps which emit ultraviolet radiation in the UVB and UVA ranges, with abrupt decrease of radiation intensity at the wavelength of approximately 330 nm. The envelopes of the lamps absorb radiation in the wavelength band below approximatey 295 nm. Each lamp is partially surrounded by a trough-shaped reflector which reflects radiation issuing from the rear half and from the sides of the respective lamp. The reflectors cause the radiation to form a high-intensity radiation field close to the exit opening of the housing. If the exit opening is located above the lamps, it is covered by a plate which transmits radiation between 300 and 330 nm and serves as a support for the body of a patient. A similar apparatus can be installed above the support, and a third apparatus can be installed laterally of the other two apparatus so as to enable a patient to expose three sides of his or her body to ultraviolet radiation in the wavelength band between 300 and 330 nm.
