Embodiment Construction

[0039] figure 1 A medical lighting device 1 for forming a lighting spot 2 on an operating field 3 for use in an operating room is shown.

[0040] The lighting device 1 in this example is in the shape of a dome 4 suspended from the ceiling of the operating room and generally having an illumination axis indicated by reference numeral AA.

[0041] figure 2 is shown with figure 1 A perspective view of the front of a similar lighting device 1, the dome 4 in this example has the overall shape of a cross formed by four lighting modules, each with four light sources 5, in this example four The light sources 5 are LEDs distributed at corresponding corners of the four corners of the square.

[0042] The LEDs are mounted on a printed circuit board 6 which is flat and as image 3 shown.

[0043] exist figure 2 , the dashed lines indicate the respective illumination axes B of the four LEDs of the illumination module to show that they converge on the surgical field 3 to form an illu...

Abstract

The invention relates to a medical lighting device for illuminating an operating field, comprising a plurality of LED light sources (5) cooperating with optical collimator elements (7) to focus light on the operating field, The LEDs are mounted on the printed circuit board (6) with different angular orientations of the illumination axis (B) passing through the optical collimator element (7). The invention is characterized in that the printed circuit board (6) is cut to form flexible tongues (10), each tongue (10) having a free end carrying an LED, each tongue (10) under stress with its free end The deformation is substantially perpendicular to the illumination axis (B).

Description

technical field [0001] The present invention relates generally to a medical lighting device for illuminating an operating field comprising a plurality of light emitting diode (LED) light sources cooperating with collimator optics to focus light on On the surgical field, the LEDs are mounted on a flat printed circuit board such that their illumination axes through the collimator optics have different angular orientations. Background technique [0002] It is known, inter alia, from document US2012 / 0182731, that a medical lighting device may comprise a plurality of LED light sources mounted on a printed circuit board, these light sources being coupled to a collimator optics, the resulting assembly being arranged so that the light beams from the light sources Converge towards the surgical field at different angular orientations to form the lighting spot. [0003] In known medical lighting devices, a planar printed circuit board is sandwiched between a carrier structure and a su...
