Description

The present invention relates to a window, a door or a facade element according to the preamble of claim 1.

Such elements are known in the art.

In addition, bulbs of various types and sizes arranged on or near the window constructions to illuminate the panel elements (e.g., patch lamps) are known.

The term "emdelight glass" is used to refer to glass panes, also known as light glass, in which LED lamps are mounted on the edge of the pane, which emit their light through refraction in the glass on the pane surfaces.

However, the known products are relatively expensive and difficult to assemble. In the known light glass, the disk edges must be processed consuming. Since the load transfer also takes place at the edge of the disc, constructive problems arise here. In general, electricians must make connections in the window constructions, so that for the installation of the window constructions and for the surface elements, the participation of professionals from different disciplines is required and therefore the installation of such products is correspondingly expensive.

The invention is therefore based on the object to provide a window, door or facade element, which overcomes the aforementioned disadvantages.

The invention solves the problem in that the at least one insulating strip has at least one lamp.

The invention is therefore based on the idea of an insulating strip for thermal insulation of a frame profile, with a surface element, such. an insulating glass pane, a window, a door or other facade elements for buildings to provide, having at least one light source.

A particularly advantageous embodiment of the insulating strip according to the invention is obtained when LEDs, in particular SMD LEDs are used as bulbs and the bulbs are integrated into the insulating strip that they are not visible in the assembled state of the insulating strip and thus protected from environmental influences or damage ,

In order to further improve the optical properties of an insulating strip according to the invention in a particularly advantageous manner, a gel reservoir may be present on the insulating strip, which bursts on mounting of the surface element on the insulating strip, so that the gel between the lamp and the surface element lays or flows there , Thereby, the refractive index jump between air and e.g. reduced or avoided the glass of the surface element.

Further advantageous embodiments of the window, door or facade element can be found in the dependent claims.

The invention further provides the insulating strip of claim 40.
