• one or multiple light heads carried on the suspension or support system, each of the light heads comprising a housing, one or multiple light sources mounted in the housing for illumination, an unsterilizable grip mounted on the housing for hand holding and moving the light heads, and one or multiple detection pairs mounted to the unsterilizable grip for receiving an infrared signal that is transmitted therefrom and reflected by an external object for conducting control and adjustment of the illumination;
• and
• a sterilizable grip mountable to the unsterilizable grip and comprising a guide channel formed therein to correspond, in position, to each of the detection pairs to allow the infrared signal to pass therethrough, allowing a surgeon to control the illumination while relocating the light heads during surgical procedures.
