Lighting systems for surgical operations

摘要

This invention relates to lighting systems for use during surgical operations or examinations. The device comprises a bundle of optical fibres having an intake area into which the light from an ellipsoidal mirror having a lamp therein can be beamed. A concave lens area located in an area facing away from the optical fibre bundle is co-axially situated forwardly adjacent the light intake area of the fibre bundle. The concave area may be formed by grinding out portion of a transparent plate and the light from the mirror may be concentrated by an aspheric lens between the mirror lamp and the lens area.
