1. A surgical light head, comprising:
a housing;
a plurality of light emitting elements arranged in the housing and configured to direct light at a target region of interest; and
a plurality of distance sensors arranged in the housing, wherein the distance sensors are configured to measure a distance to an object and are obliquely angled relative to a center line of focus of the surgical light head, wherein at least two of the distance sensors have field of views that extend outwardly from the corresponding distance sensor, wherein the field of views define respective distance sensor detection regions of interest, and wherein the distance sensor detection regions of interest overlap to define a common detection region of interest, wherein the common detection region of interest at least partially overlaps with the target region of interest.
