Abstract: An operating light is provided with a basic body (1) with flat contact surfaces (2), which are oriented with mutually different angular orientations of the respective surface normals to the working point of the operating light. A printed circuit board (6), having an underside which is flat in a premounted position, has rigid sections (8) with flat upper side surfaces pointing towards a working point of the operating light and sections (7) flexible in a preferred direction, which extend between the rigid sections (8). Light-emitting diodes (9) are arranged on the rigid sections of the printed circuit board. A lens holder (22) is provided with optical lenses (13) for the light-emitting diodes (9). The rigid sections of the printed circuit board can be placed on the contact surfaces (2) of the basic body (1) in a positive-locking manner in a mounted position, so that the light-emitting diodes (9) have lighting directions corresponding to the angular orientations of the contact surface normals.

Abstract: An operating light (36) and a process are provided for lighting an operating table via an operating light (36). The operating light (36) includes at least one first radiation source (1), which is suitable for producing light (12) with locally different, especially radially outwardly decreasing color temperature distribution (18) in a plane extending at right angles to the work area.

Abstract: An operating light (1) has a housing (2), which has a light exit opening (4); a holding system, which is coupled with housing (2) and is designed to movably hold the operating light; at least one light source (3) as well as at least one corresponding optical system to direct light emitted by the at least one light source (3) in the direction of light exit opening (4). A grip assembly unit (14) is provided approximately in the middle of light exit opening (4). The grip assembly unit (14) has a handle (5) to pivot the operating light (1) into a desired position. At least one rotating ring (11) is located between the handle (5) and the housing (2) and is rotatable in relation to the handle (5) and is designed to set various functions of operating light (1). As an alternative or in addition, a touch-sensitive sensor element (15), which is designed to set various functions of operating light (1), is located between the handle (5) and the housing (2).

Abstract: An actuating device for operating lamps (1) includes an actuator provided for actuating a number of first light-emitting diodes (6) for generating white light, on the one hand, and a number of second light-emitting diodes (7) for generating single-color light, on the other hand. A control is provided such that only the first light-emitting diodes (6) are switched on in a first operating state of the operating lamp (1) and such that the first light-emitting diodes (6) and the second light-emitting diodes (7) are switched on in a second operating state. The second light-emitting diodes (7) are designed such that a preset color rendering index is greater in the second operating state than in the first operating state of the operating lamp (1).

Abstract: A suspension device (10) with a carrier segment (12) and with at least one extension arm (14) that can be mounted pivotably thereon for moving in space devices (16, 18) that can be mounted thereon. The carrier segment (12) has a base part (24) for mounting the suspension device (10) at a mounting site. The suspension device has one or more quick-release rod modules (26) that can be detachably connected with the base part (24). The quick-release rod module (26) or each quick-release rod module (26) has a bus module (32), which contacts either a bus module (32) of a quick-release rod module (26) already embraced by the suspension device (10) or a contact device in the base part (24) when a quick-release rod module (26) is mounted on the suspension device (10).
