Such light boxes are used in living rooms, business premises and as workplace lighting on walls or Ceilings mounted to disguise one or more lights to allow light to escape to a specific area to restrict and to include additional parts if necessary. For this purpose, there are recordings within the light boxes Support and fastening means are required for the lights and in the area of the outer walls of the light box.

- It is known to arrange fluorescent tubes in elongated housings and to provide these housings with a screen so that the light can only emerge in one or more main directions. Furthermore, so-called illuminable curtain rail boxes with a curtain support rail are known, for example, from German patent specification 20 ^ 2 765, which have a light, a curtain rail, a screen and a transparent cover as essential components. The curtain rail box is composed of one or more extrusion molded parts by longitudinal tongue and groove joints. The lamp is placed loosely against and on special ribs and secured with retaining (~) clips. For the attachment of the curtain rail box, special T-profiles are formed on the top. These curtain rail boxes must only be attached to a ceiling at a distance and can only be attached to a wall using additional mounting brackets, since the side of the curtain rail box facing the wall does not offer a suitable direct contact option. The design of the curtain rail box with a large number of profile moldings requires a high manufacturing cost. A possibly necessary lateral extension of the curtain box by means of a similarly designed part is only possible with great effort. There are problems with the installation,

if, for example, the entire width of a room is to be provided with a curtain rail box and the length of the box was not cut to the appropriate length.

Special ribs, which serve as a stop or support, are used to hold the lamp with the lamp base. against or on which the base of the lamp is loosely placed, provided, and the lamp base v / ird by means of additional Holding clasps held. Such ribs and retaining clips require additional manufacturing costs, and the assembly using retaining clips requires additional material and time. Furthermore are Due to the system profiles formed on the top, these curtain rail boxes without an additional top cover to be installed only at heights at which the top of the box is not visible. Besides, the use such rail boxes limited to the coordination with a curtain support rail. The curtain rail is in most designs it cannot be removed separately at all and cannot be fitted with the curtain in all cases and dismantled.

The invention is based on the object of simplifying the production of light boxes and improving their assembly and to make light boxes available for several areas of use.

According to the invention it is provided that the outer walls of the light box horizontal and vertical fastening and / or form decorative surfaces and the support as at a distance corresponding approximately to the width of the lamp base formed from the upper boundary wall of the light channel lying partition to a receiving channel for additional parts is and the receiving channel is open at the bottom and in the area of its opening inwardly directed loading

By creating horizontal and vertical fastening and / or decorative surfaces on the outer walls of the luminaire channel, it is possible to attach the luminaire box directly to a To be attached to the wall, to a ceiling or directly in the area of the joint between the wall and the ceiling. Furthermore, in particular the decorative surfaces that are in the field of vision are embellished with panels such as precious wood. The insertion of the lamp with its lamp base is made much easier by the fact that the support for the Luminaire base zv / ischen the upper boundary wall of the ^ luminaire channel and the partition is formed, which is in the Distance of the lamp base width are arranged from each other. The lamp base now only needs to be pushed into the support to become and requires no additional holding means, which both the effort for assembly time as also reduced for material.

The receiving channel formed by the partition and the outer wall of the light box significantly improves the Possible uses of the light box, as in the receiving channel within the scope of the available space a variety of additional parts for the respective / "., can be introduced at the installation site of the light box as required. In that the receiving channel is open at the bottom is, the additional parts can easily be introduced into the channel from below and are easily accessible. The opening area can be made particularly easy by inserting a plate thanks to the inward-facing support legs or the like are closed. This plate to be used can also be designed for decorative purposes being.

When the light box comprises at least two angled several times, there is to each other by welding or riveting sheet-metal parts connected _i the manufacturing costs can be considerably reduced v / ground since no extrusion or injection molding for complex profiles required v / ground. The sheet material used is considerably cheaper than aluminum, for example. With the multiple angling of the sheet metal parts, a greater dimensional stability of the light box is achieved, and the connection of the sheet metal parts by blind rivets or spot welding represents a simple, quick and safe solution in terms of process technology.

For an exact insertion position of the lamp base can be formed on the upper boundary wall of the Leuctitenkanal be provided as a stop. However, the training of a stop is particularly cheap and simple the partition wall, if this one corresponds to the plinth depth Has Abwinxelimg to the top.

In the area of the light exit opening of the luminaire duct can be known support legs for a translucent Cover can be formed to cover the cover quickly and easily, for example for cleaning purposes or to be able to remove it to replace a defective lamp. When the support legs on both sides of the light exit opening are arranged at different heights, the light exit angle can be increased.

The insertion of additional parts into the receiving channel can be facilitated by the fact that the receiving channel at least higher in the area above one of its opening edges is designed as the thickness of the additional parts and the entire width of the receiving channel in the area directly above the support legs of the total width of the additional
