It is an object of the present invention to provide a window component of the kind described above, which is basically based on similar optical principles but at the same time produces a greater amount of light.

The solution of this problem is provided by a window component according to the invention in the form referred to in the preamble which characterizes the features of the independent claims. As part of the experiments associated with the present invention, it has been found that it is possible to produce a greater amount of light if the light is irradiated directly on one front of the panes. The basic structural design of the insulation window, surrounded by a window frame structure in which at least two separate panes of glass are moved around the edge area, persists as part of the present invention, so that two panes of glass (more than two panes are possible) are commonly enclosed. The question arises where the luminaire is accommodated to allow light to be irradiated into at least one front of the panes when using the window frame structure. According to a first possible embodiment of the invention, this problem is advantageously provided that at least one pane in which the luminaire shines therein is designed to be short in length and / or width compared to at least one further pane of said window part. Resolved. The lighting means is preferably installed in the space between the front of the short pane and the window frame structure. By this means, the sum of the dimensions of the short pane area and the dimensions of the luminaire can be made approximately equal to the dimensions of the non-short pane. In this way, the luminaire can be positioned immediately with respect to the front face of the short pane and can use a window frame structure of a simple construction which commonly surrounds the panes. The luminaire has a straight boundary so that, for example, the window frame structure can be installed in a conventional slot in the window frame.

A window frame longitudinal section having a substantially U-shaped cross section is preferably used for such a window frame structure. Such a window frame longitudinal section has two legs, each of which encloses at least one pane, and the rungs preferably move substantially perpendicular to these two legs and connect them together. The lighting means may be arranged on the legs of the window frame longitudinal section. In doing so, the luminaire is mounted on at least one transverse or longitudinal front of the panes. Basically, it is of course also possible to arrange the luminaires on both the longitudinal and transverse fronts.

In the first embodiment of the invention, it is preferable that LEDs of other designs are used as luminaires, for example LED-SMD or the like, which luminaires exist in a very small type of structure and consume very little current. do. By way of example, these luminaires can be arranged in large quantities in a row, so that space can be installed in the window frame structure of such window parts.

It is of course also possible to shine light into the front of the multiple panes of the window part using the luminaires in the window frame work of the invention, the luminaires being preferably arranged in series. There are many optical possibilities in this case. By way of example, the luminaire for irradiating light into one of the panes can be controlled to emit essentially white light, and the luminaire for irradiating light into the other pane can essentially be controlled to allow them to emit color. have. In this case, white light can be emitted from the window component essentially beyond its surface on one side of the window component and colored light can be emitted to the other. By way of example, white light is internally and colored light is externally (or vice versa), where window components are installed on the exterior walls of the building, as in a typical window. In this case, a window part having its inner face facing this room acts to illuminate the room or to assist in the illumination of the room while at the same time the colored light is emitted outward to make the window appear colored and have a decorative effect. Indicates. Furthermore, there are several possibilities due to the fact that the color of the light of the luminaire can be arbitrarily changed by suitable control elements. As an example of an LED of another design allowing proper control, LED-SMD or the like is used as the luminaire. In addition, these luminaires have the advantage that they can be installed in relatively small useful spaces between one front of the panes and the window frame structure. These luminaires also have the advantage of very low energy consumption and a very long lifetime compared to typical luminaires such as fluorescent lamps, filament lamps or the like. These luminaires also require virtually no repair.

When the panes are discussed as part of the present invention, it should be understood that the panes are made of either pure glass, preferably transparent glass or artificial glass. Examples of suitable artificial materials are suitable synthetic materials such as polyacryl, polymethacryl or optical fiber conductors with similar properties and slightly absorbing light.

According to the invention, the control device is for example for luminaires, for example by means of which they are not only the collar, but also the sunlight (the dimming function) and / or the person in the room or the person approaching the room (by the movement of the sensor or the like) or It is preferred to be used to adjust according to the specified program (eg according to day time).

It is preferred that pointed grids, linear grids or similar grids are used to obtain the desired light diffusing effect and light deflection on the pane surface, which are applied to at least one side of the panes, which are printed, fixed or etched, sanded, It is desirable to be able to achieve it by coating or engraving. As another method for achieving the light diffusing effect in one region of one surface of the panes, a structural displacement can be made, for example, by suitably focused laser radiation within the region defined within the panes. have. The emission of light diffused over the surface of the pane can also be achieved by this means.

According to a second possible embodiment of the invention, the luminaire is mounted in a strip or PCB. Again, it is desirable to use other designs of LEDs, for example LED-SMD or similar LEDs, for example they can be mounted in transparent plastics. The thin plank-shaped strip containing the luminaires has a flat, compact, rectangular block shape, and also enables the luminaires to be installed with very space savings. Another advantage is that the luminaires are installed to be waterproof and to protect against the effects of weather and mechanical influences. In addition, such a leuchtmittelleiste can be quickly replaced when necessary in the event of a failure, saving installation cost (Montagekosten). Access to the luminaire strip is possible, for example, by removing or opening the window frame longitudinal section from the window frame structure.

Such luminaire strips (LED strips) can be wider than one front of the panes. By way of example it may also extend beyond the space defined by the two fronts of at least two panes and the distance between them. By such a structural solution, it is unnecessary, unlike the above-mentioned embodiment, to design a short length and width of one of the panes, and the luminaire strip is under the front of the panes, ie between the panes and the window frame structure. Can be arranged. At the same time, it is unnecessary to irradiate light into the two panes. Rather, the luminaire can be inserted just above one side of the luminaire strip so that they irradiate light only within the front of one pane. Instead, the luminaires are arranged in strips below each facade of the two panes and they are switched if necessary so that light can be provided only into the facade of only one or two panes of panes.

The above mentioned luminaire strip is preferably a PCB on which other designs of LEDs or similar LEDs are mounted, where the luminaire is bonded to or protected by the PCB with a transparent material. By this embodiment of the invention it is preferred that each end of the luminaire strip and at least two panes is also surrounded by a window frame structure. The window frame structure generally includes a longitudinal section of the window frame. The longitudinal section of the window frame may be designed to have a substantially U-shaped cross section and may include one of the legs forming the two legs surrounding the front of the window frame structure and the ends of the panes. The bonding process of the LED can also be performed directly at the end of the window frame. This allows for precise positioning and better fixation of the luminaire and simplifies replacement possibilities. These panes can in turn be made of pure glass or artificial glass. The space between two or more panes is preferably defined by an abstandselement, which is arranged between them so that a luminaire strip is usually placed under the panes and below the isolation element.

The features mentioned in the dependent claims relate to better solving the problem according to the invention. Other advantages of the present invention can be seen from the detailed description below.

The invention is described in more detail below on the basis of an embodiment with reference to the accompanying drawings. here,

1 is a schematic simplification of a partial cross section in the longitudinal direction through a window component according to a first embodiment of the invention;

2 is a similar schematic schematic simplification of the longitudinal section through a window part according to a second embodiment of the invention;

3 is a perspective view of a luminaire strip according to the invention.

First, reference is made to FIG. 1. This figure shows a longitudinal partial cross section through a window part according to the invention which is diagrammatically simplified. In principle, it can be seen that it has two plates 100, 101 made of glass or artificial glass, which are arranged at a distance from each other so that the space 103 between the two plates is as in a thermal insulation window. There is. There may be three or more plates (such as having three panes). Air under normal pressure or a gas having good sound absorption properties, for example argon, may be in the space 103. The gap retainer 105, which usually has an additional sealing function, is used as a gap holder in the edge region of the two panes 100, 101 or is provided with a separate sealing mixture.

As shown in this figure, in this embodiment, one of the panes 100, 101 is designed to be shorter in at least one expanding direction (in the vertical or transverse direction) compared to the other pane 101. As a result, there is a space 112 between the pane 100 and the front surface 108 of the window frame structure 110. Usually, this constitutes a row of LEDs or the like, where the LEDs or the like are arranged next to each other in a slate shape or behind each other (in the middle of the figure). These luminaires 102 immediately emit their light beyond the front 108 into the pane 100, in which the light is guided and at least partially deflected at almost right angles. This light deflection, light diffusion, is achieved by printing the pane 100 as an example on the pointed grid 107 or on an outer surface having another structure for deflection. Thus, light is emitted as light diffused over the surface of the pane, as indicated by the arrow in FIG.

A window frame with a substantially U-shaped window frame section with two crosses 111 and 109 facing the panes on the outside, substantially perpendicular to the cross section 111 and the window frame longitudinal section, surrounding the two panes 100 and 101 It is used as the structure 110.

Another embodiment of a window frame component according to the invention is described below with reference to FIGS. 2 and 3. Figure 2 shows a longitudinal partial cross section through the lower part of the window frame part according to the invention which is schematically simplified. Two panes 12 and 13 are provided which can be made of pure glass or artificial glass. The space 103 between the two panes 12, 13 is defined by the clearance holder 18. The clearance holder 18 has an expanded rectangular shape example, and has a rectangular cross section. As can be seen in the drawing, the window frame structure 14 closes the luminaire strip 10 with the lower ends of the two panes 12, 13 and a flat, rectangular cross section. The window frame longitudinal section 14 has an almost U shape with two legs 17, 15, each of which faces one outer face of the pane, surrounds the panes, It has a crossbar 16 that connects the legs 17 and 15 and moves side by side at a predetermined distance from the two fronts 11 of the two panes 12 and 13. The luminaire strip 10 is aligned between the two pane fronts 11 and the rungs 16. In this embodiment, the luminaire strip 16 is designed such that the LEDs are only aligned on one side below the front 11 of one 12 of the two panes. This luminaire thus emits light into the front of the pane 12. By way of example, due to the fact that one surface of the pane 12 is printed with a dot grid, light is emitted outward beyond the surface of the pane 12 in the direction of the arrow of FIG. 2. The LEDs 102 are made of a transparent material and are thus bonded into the LED strip 10 which is protected from the effects of weather. In addition, the LEDs can also be aligned where the front face 11 of the second pane 13 is located, so there is the possibility of emitting light over the front face here if necessary. In doing so, the luminaire can be controlled such that one or more rows of luminaires are selectively switched on, and if necessary the luminaire is controllable to emit white or colored light as differently or in different colors as possible. By this means, it is possible to create a color lighting effect and change the color of light emitted inward or outward from the window part. The brightness can also be changed by appropriate control of the luminaire.

3 illustrates an enlarged perspective view of an LED strip 10 that can be used in the embodiment for the window component according to FIG. 2. The luminaire strip (LED strip) 10 has a relatively flat and enlarged rectangular shape. As a result, the installation height is very low. The luminaire strip 10 is made of a transparent plastic material in which the luminaire 102 and the necessary power supply wires 20 are joined. The luminaire 102 is placed on a kind of PCB 21, with the result that the printed board has the provision of conductor tracks 22, which are connected to individual luminaires (LEDs) 102. The luminaires 102 can be arranged in rows and combined in groups as shown in FIG. 3. Usually each luminaire can be activated electronically. The entire PCB 21 is bonded in a transparent plastic block into which the wires 20 for the main power supply can come. As a result, it is possible to connect and replace the luminaire strip according to FIG. 3 very easily and quickly in the window component according to FIG. 2 if necessary.
