Abstract: The invention relates to a lighting arrangement, which is implemented by means of light emitting diodes or LEDs, characterized in that the lighting arrangement comprises a lighthead support (1 ), including one mounting plane (10) which consists of a plurality of mounting brackets (2; 2 1 , 2 2 , 2 3 ,... ) for light elements which are set in a single plane, said mounting brackets being rod-like members which are aerodynamic at least in a direction (B-B) transverse, most preferably perpendicular to the mounting plane (10), and across which the air is able to flow, said mounting brackets being fitted with a plurality of light elements (3) containing at least one light emitting diode (31 ), such that said light elements (3) are for the most part thereof located inside the mounting brackets (2), whereby at least some of said light elements (3) comprise a light source or LED (31 ), whereby said mounting brackets (2; 2 1 , 2 2 , 2 3 ,... ) are disposed in the proximity of a ceiling (K) of an operating theatre or the like facility, essentially above an operating table (LP) so as to be located immediately below a supply air frame (TF) of the facility to be illuminated and in such a way that a supply air (C) flowing through the supply air frame (TF) is adapted to retain its constant angle of incidence (d1, d2) with the mounting plane (10) regardless of where the object of illumination is located in the to-be-illuminated facility with respect to the mounting plane (10) or regardless of the direction of a light beam generated by each light source or LED.
