A light fitting (1) has a light source (4) which is arranged at the narrow side (18) of a plate-like light guide (3) from which light serving for room illumination is irradiated, at least from a part region of a broad side of the light guide (3). The light fitting (1) has a light fitting carrier (2) with at least two carrier elements (16b), lying opposite one another, for holding the light guide (3). The carrier elements are arranged on carrier parts (16, 16a). Also, a reflector arrangement (5) is associated with the light source (4) which at least partially surrounds the light source (4) in a free region neighboring the light guide (3). |

DETAILED DESCRIPTION A object of the invention is to find, whilst maintaining the flat manner of construction, a simple manner of construction for a holder of the light guide and of the reflector arrangement on a light fitting carrier.
This object is achieved by means of a ceiling light fitting having a horizontally directed light guide from at least a portion of a broad side of which room illumination light is irradiated.
The light fitting includes a light fitting carrier which has at least two elements lying opposite one another, for holding the light guide.
These elements are arranged on carrier parts and are engaged below the light guide.
The light source has a reflector associated therewith and the reflector is arranged so that it at least partially surrounds the light source in a free region neighboring the light guide.
With the configuration in accordance with the invention, the light fitting carrier and the reflector arrangement form a constructional unit, in which the light guide--whilst maintaining an advantageous intake and emission of light--can be held in a simple and reliable manner.
Thereby it is particularly advantageous to arrange the carrier parts, having the carrier elements for holding the light guide, at one and the same height with the light guide, whereby not only is a low construction provided, but whereby also an optimum emission of the light from the light guide and room illumination is attained.
Further, it is the object of the invention to so configure the light fitting of the kind concerned that the reflector arrangement or a reflector can be readily installed or disinstalled on the light fitting carrier, whilst maintaining a simple configuration.
In accordance with a further development of the invention, for the connection of the reflector arrangement or of the reflector with the light fitting carrier there is provided at least one plug-in connector which can be realised in a simple and compact construction and can be integrated into the light fitting construction, and furthermore allows a simple and rapid installation or dis-installation
