Abstract: An illumination device and process illuminate a surface of an object. The device includes plural illumination units and a signal processing control unit. Each illumination unit illuminates the surface with a maximum irradiance, wherein the device illuminates the surface with a maximum total irradiance that depends on the maximum irradiances of the illumination units. The device captures a maximum total irradiance user specification of the device or units. The control unit controls the maximum irradiance of each illumination unit independently and responds to the user specification by predicting the maximum total irradiance of the device operated according to the user specification, compares the predicted maximum total irradiance with a specified upper threshold and if greater than the upper threshold, controls one or more illumination units depending on the user specification such that the actually achieved maximum total irradiance is less than or equal to the upper threshold.

Abstract: An illumination device (100) includes an illumination unit (1, 2) which illuminates a surface (Ob). The position and the orientation of the illumination unit (1, 2) relative to the surface (Ob) can be changed. A distance sensor (4.1, 8.2) measures an indicator of the current distance between the illumination unit (1, 2) and the surface (Ob). A signal processing control unit (10) is configured to control an output unit (6.1, 6.2) of the illumination unit (1, 2). The controlled output unit (6.1, 6.2) outputs an indication of how much the measured distance deviates from a predetermined reference distance (Ref1, Ref2).

Abstract: An illumination device (100) with a main illumination unit (1) and an auxiliary illumination unit (2). Each illumination unit (1, 2) includes a plurality of light source groups, respectively, which can be controlled individually. The maximum illuminance achieved by the main illumination unit (1) on an illuminated surface (Ob) is several times greater than the maximum illuminance achieved by the auxiliary illumination unit (2). The dx light field (light field diameter) of the main illumination unit (1) on the surface (Ob) has a significantly smaller area than the dx light field of the auxiliary illumination unit (2). The switched-on auxiliary illumination unit (2) is able to reduce the contrast of the illumination device (100).

Abstract: A lighting unit (100) for a medical luminaire (150) has a number of groups of LEDs (110, 110?, 110?) that are connected to a common planar printed circuit board (115). Each LED (112, 112?) of at least one of the groups (110, 110?) is associated with a respective optic (122, 122?) by which a respective LED-optic pair (120, 120?) is formed. The respective optics, based on the structure (328), specify a tilt angle (125) of a central light beam axis (124, 124?) of an emitted light beam of the LED optics pair in a tilt direction (627) of the respective LED optics pair. The tilt direction is defined such that the respective light beam axes of the emitted light beams of the LED optics pairs from the at least one group of LEDs are at least partially skewed in pairs with respect to one another.

Abstract: An operating lamp has a lamp body with a lamp surface directed towards a light projection surface. The lamp body has a central axis and the light projection plane extends at a preferred working distance from the lamp surface and at right angles to the central axis. The operating lamp has N light modules arranged on the lamp surface on a first circle with a centroid that coincides with the central axis. The light modules are aligned to each emit a light bundle with a respective principal axis towards the light projection plane—the principal axes forming, with the light projection plane N intersections, an ellipse with a centroid coinciding with the central axis. One of the light modules rotates about a rotation axis that passes through the light module, intersects the central axis has a light bundle principal axis that does not intersect the central axis.
