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 wit 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.

Abstract: The invention concerns a mounting bracket to securely hold elongated tubular lamp members. The mounting bracket has a stationary part which can be fixed to a static structure, and a movable part which is detachably fixed to the stationary part in such a way that both parts fix the tubular lamp in place.

Abstract: A lamp assembly comprising at least one elongated fluorescent tube and an elongated reflector of trough-like shape having a longitudinal center plane coincident with the longitudinal axis of the fluorescent tube. The shape of the reflector (10) is variable. Adjusting devices (34, 36) at least at one end of the reflector (10) changes the position of the free longitudinal edges (32) of the reflector (10), which forces the shape of the reflector (10) to change also.

Abstract: A halogen lamp assembly comprising a housing (12) having a light exit opening (14) and a halogen bulb (28) in the housing, means supporting the halogen bulb (28) so that it can slide axially in the housing (12) and spring means biasing the bulb in the direction of the light exit opening (14) by a clamping ring (18) removably attached to the forward edge (26) of the bulb for pushing the halogen bulb lamp (28) against the force of the spring means (42) into a rear position inside the housing (12), the halogen bulb (28) is pushed by said spring means (42) into a forward position by removal of the clamping ring (18) from the housing (12), wherein its front edge (26) projects out of the housing (12), a socket (30) holds the halogen bulb (28) attached to a socket clip (32), which is supported on two pins (28) so that it can slide in the axial direction of the housing; at least one pin (28) being surrounded by a helical spring means (42), which is held between a rear housing stop (40) and the rear surface of the soc

Abstract: A halogen lamp assembly comprising a housing, a halogen bulb installed in the housing, and a light exit shield removably mounted in the light exit opening of the housing, a support ring with a radially inward-projecting ring land, a first ring-shaped groove on inside radial surface of said support ring, a first O-ring mounted in said groove, said ring land being in front of the forward of the first O-ring, a first shield disk resting against the rear surface of the ring land, and a shield grid removably mounted in the support ring.

Abstract: Lamp hinge assembly for connecting a lamp pole part (10) to a lamp head part (16) so that they can pivot with respect to each other, comprising a stop screw permanently attached to one of the pivoting parts, a stop (28) permanently attached to the other pivoting part to limit the pivot angle between the lamp pole part (10) and the lamp head part (16), a stop disk, which rotates with the pivoting motion of the parts, inserted between the stop screw (14) and the stop (28), said stop disk (20) being provided with two radially projecting lobes (22, 24), which are separated from each other by a predetermined angle, and each of which comes to rest against one side of the stop (28), and in that, approximately midway between the lobes (22, 24), the disk has a stop tab (26), against either side of which the stop screw (14) can come to rest, depending on the position into which the parts (10, 16) have been pivoted.

Abstract: A wide-beam, indirect lamp assembly comprising an elongated lamp housing symmetrical about a vertical center plane (26) and transparent to the light directed downward and open at the top and including at least two fluorescent tubes disposed on each side of, and equal distances away from the center plane. At least one reflector is provided for each tube in the lamp housing near each tube, said reflector operable to deflect at least part of the light beaming upward from the tube. Each reflector (30) is made of a perforated sheet metal and comprises, in vertical cross section, a first, generally vertical section (32) on the side of the associated fluorescent tube (28) facing the center plane (26), a second, generally horizontal section (34) on the top surface of the associated fluorescent tube (28); and a third section (36), adjoining the second section (34). The third section (36) slants upward and away from the center plane (26).

Abstract: Apparatus for photodynamic irradiation comprising a housing (10), a lamp (16) mounted in the housing and a reflector (18) surrounding the lamp. A filter unit (40) is mounted in the beam path of the lamp and the reflector, and a light outlet (26) in the housing following the filter unit. A dosage device accurately meters the radiant energy delivered by the apparatus to a patient.

Abstract: A wide-dispersion indirect lamp assembly with an elongated lamp housing (14), symmetric to a central, vertical plane (26), and which prevents at least most of the light from escaping downward. The assembly includes two fluorescent tubes (28); and a reflector (30) above each of the tubes. Each reflector, seen in vertical cross section, slants upward and away from a point (32) on the upper half of the circumference of the fluorescent tube. The point (32) is preferably shifted away from the apex line (34) of the circumference of the fluorescent tube toward the central plane (26) of the lamp housing (14).
