Abstract
Illumination device () for a motor vehicle headlight for detection and targeted masking of a light-emitting object () present in front of the illumination device () in segmented light distribution, which illumination device () comprises the following: a light generation unit (), having a plurality of light pixel groups (a,b ,c,d) a light sensor device () for detecting light of a light-emitting object () with a first light sensor () having several first sensor pixels (), a control unit (), which is connected to the light generation unit () and the light sensor device () and is designed to control the light generation unit () for generating the segmented light distribution, wherein one sensor pixel () can detect light in a detection solid angle (DRa, DRb, DRc, DRd) and is respectively associated with a light pixel group (a,b,c,d), and wherein the light incident on each first sensor pixel () can be detected as a luminous flux value associated with the respective first sensor pixel (), wherein the light sensor device () additionally has a second light sensor () for measuring distance, and wherein the control unit () is designed to individually compare the luminous flux values detected by the respective first sensor pixels () with a respectively definable threshold and, if the threshold is exceeded, to reduce the luminous flux of the corresponding light pixel groups (a,b,c,d), wherein in the event that it is determined that the threshold has been exceeded in two detection solid angles (DRa, DRc) and it is determined that the threshold has not been exceeded in a detection solid angle (DRb) between these two detection solid angles (DRa, DRc), the control unit () is designed to derive a presumed object width and compare it to an actual object width, which actual object width can be determined by means of the second light sensor (), wherein, if the presumed object width matches the actual object width, the control device () is designed to reduce the luminous flux of the corresponding light pixel groups (a,b,c).
