Abstract: A surgical light head and proximity detection method includes 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. At least two of the distance sensors have field of views that overlap to define a common detection region of interest and the common detection region of interest at least partially overlaps with the target region of interest. The light head may have a plurality of integrally formed tilted seats that position the distance sensors relative to a center line of focus of the surgical light head. The distance sensors may be integrated in the housing via an optical component that is sealed relative to the housing and covers the distance sensor while enabling transmission and receipt of distance sensing signals therethrough.
