PHOTOOTRANSMITTING BODY PARTICULARLY FOR ILLUMINATION OF OPERATING ROOM* ETC*
Document Type and Number:
Japanese Patent JPS5584159
Kind Code:
A
Abstract:
A light guide with a liquid light transmissive medium is connected to a variable pressure source, such as a controllable pump, and a hydraulic pressure take-off is connected to the light guide, for example adjacent the light exit window, to control the position of a positionable element, typically an optical system, such as a fluid lens, a movable lens, a diaphragm or the like, with respect to the exit light window from the light guide tube as a function of the pressure applied to the light transmitting liquid within the tube. Thus, the light guide can function simultaneously as a light guide and as a hydraulic servo pressure control element, to control the light output or the position of another element linked to the hydraulic servo positioning piston-cylinder arrangement coupled to the light transmitting fluid in the light guide.
