Problems solved by technology

[0008] A disadvantage of this lighting arrangement is that, for a given level of diffuse illumination of the operating area provided by the second component, the power required by both lamps is relatively high
[0009] In addition, diffuse lighting depends on the properties of the materials that make up the ceiling and therefore cannot be predetermined when manufacturing the lighting fixture

Embodiment Construction

[0041] FIG. 1 shows a first embodiment of a lighting device in an operating room, denoted as a whole by the reference number 2 .

[0042] The lighting device 2 is suitable for illuminating a lighting field 4, for example a surgeon's operating field on a patient. The lighting field 4 extends in a substantially horizontal lighting plane E-E.

[0043] The lighting device 2 includes a housing 6 and a first lighting assembly 8 and a second lighting assembly 10 arranged above the lighting area 4 . The housing 6 defines a central axis C-C substantially perpendicular to the illumination plane E-E.

[0044] The housing 6 forms a lighting support for the first lighting assembly 8 and the second lighting assembly 10 .

[0045] The housing 6 includes an opaque four-lobed bell 12 having four lobes (lobes) 14 . These four petals 14 lie in the same plane and protrude radially with respect to the central axis C-C. The bell 12 is substantially closed on the side facing away from the lighti...

Abstract

The invention relates to a lighting device for illuminating a lighting zone (4), the device comprising a lighting support (6) with a dome (12), a first light source (20) and a separate light source from the first light source A second light source (40). The second light source (40) and the first light source (20) are arranged on the same side of the dome (12). The lighting device comprises a light diffusing device (44) arranged between the second light source (40) and the lighting area (4) for propagating light beams from the second light source (40) to the lighting area (4). The above-mentioned device is suitable for a lighting device in an operating room.

Description

technical field [0001] The invention relates to a lighting device for illuminating a lighting area, the device being of the type comprising: a lighting support having a bell; a first lighting assembly supported by the lighting support, the first lighting assembly comprising a first light source disposed facing the lighting area and adapted to illuminate an illumination range in the lighting area with a first intensity along a first lighting direction extending from the lighting support towards the lighting area; by the lighting support A second lighting assembly supported by a member, the second lighting assembly includes a second light source different from the first light source and adapted to illuminate the lighting range with a second intensity along a second lighting direction. [0002] The invention is particularly suitable for devices for illuminating an operating field in an operating room. Background technique [0003] Document US-B-5 539 626 describes a lighting d...
