1. An operating room light comprising:
- a light casing having a central region;
a plurality of arms (6, 8, 10, 12) connected to the central region;
a plurality of LED illumination modules, each module comprising;
a pivotable plate (32) pivotably connected to one separate arm of the plurality of arms; and
an LED arrangement (34) supported by the pivotable plate (32); and
a focusing unit comprising;
a rotary handle (14) having an axis of rotation;
a displaceable element coupled to the rotary handle, the displaceable element displaceable in translation along the axis of rotation of the rotatable handle when the rotary handle rotates; and
at least one pivot bar pivotably mounted in a rocker point (36), the at least one pivot bar having one end operatively coupled to the displaceable element and the other end operatively coupled to the pivotable plate, the at least one pivot bar displacing the pivotable plate when the pivot bar moves in a rocking motion.

Abstract
A light for operating rooms includes a light housing (2), several LED illumination modules that are adjustable for focusing purposes, and a unit for focusing the illumination modules. In order to prevent the light from being accidentally moved from the center of gravity on a gimbal mount, the illumination modules encompass a swivel plate (32), which is pivotally mounted on the light housing (2) and is provided with an LED array (34) that is arranged thereon.

9. An operating room light comprising;
-
a light casing; a plurality of LED illumination modules displaceable for focusing purposes, the illumination modules including a pivot plate (32) pivotably fixed to the light casing (2) and have an LED arrangement (34) arranged thereon; a focusing unit for focusing the illumination modules, the focusing unit including a displacement element which is displaceable with respect to height by way of a rotary handle (14) and to which there is pivotably mounted—
at least one pivot bar (30) mounted pivotably in a rocker point for displacement of the pivot plate (32), with the performance of a rocking movement, wherein the displacement element is in the form of a displacement cross member (20).

10. An operating room light comprising:
-
a light casing; a plurality of LED illumination modules displaceable for focusing purposes, the illumination modules including a pivot plate (32) pivotably fixed to the light casing (2) and have an LED arrangement (34) arranged thereon; a focusing unit for focusing the illumination modules; and a collimator lens, which has the geometry of a circular truncated cone and which has a peripherally extending peripheral surface (58), a light entry surface (60) which is downward in the position of installation and has a recess (62) and a light exit surface (64) which is upward in the position of installation, wherein a radius of curvature of the outer peripheral surface (58), the height of the collimator lens (50), the light entry surface (60), the size and geometrical configuration of the light exit surface (64) and a surface of the light exit surface (64) are matched to each other to avoid blue light in the edge region of the lens by mixing into a central region. - View Dependent Claims (11)
