Abstract
A surgical lighting illumination control device includes a suspension system; light heads mounted on the suspension system and each including a housing, light sources mounted in the housing, an unsterilizable grip mounted on the housing for hand holding and moving the light heads, and detection pairs mounted to the unsterilizable grip for receiving an infrared signal that is transmitted therefrom and reflected by an external object for control and adjustment of the illumination, each detection pair including an infrared transmitter and an infrared receiver; a compensation control mechanism connected to the detection pairs and including a control operation unit and environment temperature compensation units connected to the control operation unit; and a sterilizable grip mountable to the unsterilizable grip and including a guide channel formed therein to correspond, in position, to each of the detection pairs to allow the infrared signal to pass therethrough.
