DEVICE AND PROCESS FOR UNIFORMLY LIGHTING AN OPERATING AREA
First Claim
1. A device for uniformly lighting at least one lighting field, the device comprising:
- a lighting fixture housing;
a lighting unit with a plurality of lighting elements accommodated in said lighting fixture housing;
a camera having a camera acquisition area;
a control unit for providing actuating signals for actuating said lighting elements with data acquired by said camera in said camera acquisition area as image segments;
an image processing unit determining parameters of said image segments to light the at least one lighting field, wherein said control unit adjusts the actuating signals, for the plurality of lighting elements, to reduce the differences in the luminosities of the image segments.

Abstract
A device and a process are provided for uniformly lighting an operating area for performing the lighting of an operating area (2) of a bed (30) by means of a lighting unit (3) such that a selected lighting field (13) is lighted uniformly. The image signals of a camera (7) are sent to an image processing unit (17), in which the image signals are analyzed and the individual lighting elements (6) are switched via the control unit (18). A lighting situation is acquired in the process for initializing and operating this lighting system and a lighting field (13) of interest is selected. The image signals are analyzed during the operation and sent to the control unit (18) in order to switch the lighting elements (6) such that uniform lighting is obtained in the first lighting field (13).

11. A process for operating a lighting system for uniformly lighting a lighting field, the process comprising the steps of:
-
providing a plurality of lighting elements; switching the lighting elements on one after another in a sequence to provide a plurality of switch-on events; acquiring an image with at least one camera for each of said switch-on events of every single lighting element; storing each acquired image in a first data field; in a continuous sequence analyzing a data image acquired by the at least one camera and comparing the data image acquired with the first data field; providing a first parameter field; continuously adjusting actuation parameters of the first parameter field; continuously adjusting individual lighting elements and the control unit continuously actuates the lighting unit according to the first parameter field. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
