Abstract: A protective tubular light is proposed, which basically consists of a transparent light tube (10) in which a fluorescent lamp is positioned. The fluorescent lamp is carried by a lamp support. The light tube (10) can be tightly sealed on either end by a cover consisting of an outer cover part (60) and an inner cover part (80). Serving to produce the tight seal is a sealing ring (62), which is pressed against the inner wall of the light tube (10) by the axial movement of the inner cover part (80) in conjunction with a tension cone (83) furnished on the inner cover part (80). The electrical connection of the fluorescent lamp and the network cable is provided by plug and coupling parts (30, 40). To produce or break off the electrical connection the coupling part (40) is driven against or withdrawn from the plug part (30) by the inner cover part (80), which can be moved axially.

Abstract: To allow optimum adaptation of irradiation equipment, especially irradiation equipment for photodynamic therapy, to the individual anatomy of a patient, an irradiation head (1) is provided with a plate-shaped middle section (2) and plate-shaped lateral leaves (3), mounted on the middle section (2) in such a way that they can swivel. The irradiation head can be rotated about two perpendicular axes (U, W), and its height can be adjusted. With its lateral leaves (3) extended, the irradiation head (1) has a plane configuration formed by the middle section (2) and the extended lateral leaves (3). The configuration is suitable for areal irradiation of the trunk or extremities of a patient. It can also be configured to a rectangular U shape suitable for three-sided irradiation, when the lateral leaves (3) are swivelled 90°. Radiation sources, e.g.
