摘要:
A medical light (100) has an illumination unit (10) having lighting means (20) and optical means (30) for generating a light field (200), wherein the lighting means (20) are formed by an essentially punctiform LED light source (21) and the optical means (30) have a plate-shaped collimator (40) and a cover pane (50). The collimator (40) has a central area (42), which is provided with light-refracting structures (43) on a side facing away from the LED light source (21), and an outer area (46), which is provided with structures (48) designed for total reflection on a side facing toward the LED light source (21), wherein the cover pane (50) is provided with a lens structure, which has a plurality of individual lenses which each project the light emitted by the collimator (40) onto the object plane. The rear side of the central area of the collimator facing toward the LED light source is provided with partial surfaces (45, 145), which have an inclination in relation to a plane (E3) of the collimator (40), in order to asymmetrically expand the light field (200) in one direction.
