Description

(1) The invention is explained in more detail below with reference to the accompanying drawings, wherein:

(2) FIG. 1 shows a machine having a work lighting according to an embodiment of the invention,

(3) FIG. 2 shows a lighting means according to the invention, and

(4) FIG. 3 shows a work lighting according to an embodiment of the invention, illustrated separately from a machine.

(5) Elements with the same function and mode of operation are each indicated by the same reference numerals in the figures.

(6) FIG. 1 shows a machine 200 in the form of a tractor with a work lighting 100 mounted thereon used to generate an adaptive working illumination. The machine 200 has a cabin 210 for a user of the machine 200 and the work lighting 100. As shown in FIG. 1, an environment detection unit 40 is arranged in the cabin 210 of the machine 200 in the field of view and at eye level of a user (not shown) located in the cabin 210. Further environment detection units 40 are arranged in the vicinity of the lighting means 10.

(7) The work lighting 100 of the machine 200 shown in FIG. 1 has eight (four are shown) lighting means used to generate the work lighting. The work lighting 100 also has six (three are shown) environment detection units 40. The environment detection units 40 each have a light sensor for detecting light signals and generating a control signal based on the detected light signals. The work lighting 100 also has an adjusting unit 70 in the form of a manual control unit, an adjusting unit 50 with a control unit in the form of an LCU, and an adjusting unit 60 with a control unit in the form of a BCM for controlling and/or regulating the working illumination of the individual lighting means 10, wherein an LCU is configured to adjust the working illumination of at least one of the lighting means 10 as a function of the different control signals of the environment detection unit. In addition to the light sensors, the environment detection units 40 have an image sensor for capturing image signals from the environment of the work lighting 100 and generating a control signal based on the captured image signals, and an object detection unit for detecting at least one object in the vicinity of the work lighting 100 and generating a control signal based on the at least one detected object.

(8) The lighting means 10 are each designed to generate work lighting with about 2,000 lumens. An eye-tracking system 30 is further arranged in the cabin 210 for capturing viewing information of a user of the work lighting 100 and for generating an eye-tracking control signal based on the captured viewing information. In addition, or as an alternative to the eye-tracking system 30, a head-tracking system with a mode of operation corresponding to the eye-tracking system can also be arranged in the cabin 210. Accordingly, the LCU is configured to adjust the working illumination of at least one of the lighting means 10 according to the control signals of the environment detection unit 40 and according to the eye-tracking control signal of the eye-tracking system 30.
