A thermally insulated door assembly includes first and second panes of light transmissive material, a light assembly, and a heat sink. The first pane and the second pane are spaced apart from each other by a separation gap to define an interior chamber. The light assembly is in the interior chamber between the first pane and the second pane, and is configured to generate light within the interior chamber. The heat sink is disposed within the interior chamber and coupled with the light assembly and an inwardly facing surface of the first pane. The heat sink is configured to conduct thermal energy generated by the light assembly onto an inwardly facing surface of the first pane and into the interior chamber such that the inwardly facing surface of the first pane and the interior chamber are heated by the light assembly.

A glass panel includes a first glass substrate, a second glass substrate, a spacer profile at the periphery of the glass panel between the first and the second glass substrate. There is an intermediate substrate in the intermediate space between the first and the second glass substrates, the substrate having a first coefficient of thermal expansion, and means to maintain the intermediate substrate within the intermediate space. The panel also includes a second profile, having a second coefficient of thermal expansion, positioned facing the inner face of the spacer profile within the intermediate space between the first and second glass substrates of the glass panel. The second profile carries the means to maintain the intermediate substrate within the intermediate space. A difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion is less than or equal to 20%.

Disclosed is a pane unit (10), which comprises a frame structure (12) formed from a plurality of profiles (14), at least two outer panes (16, 16′), and at least one middle pane (18). The panes are each connected or attached to the frame structure (12). The pane unit (10) moreover comprises at least one functional element (20) used for the illumination of the at least one middle pane (18), which functional element (20) is inserted into at least one chamber (24) provided in the profiles (14). The plurality of profiles (14) are coupled with each other by means of at least one connection element (28), wherein the at least one connection element (28) engages with the profiles (14) in such a manner that the pane unit (10) is hermetically sealed.

A light transmitting panel assembly includes a first panel, a second panel, a frame, a gap between the first panel and the second panel, and a first active component located between the first panel and the second panel.

An apparatus includes first, second, and third glass portions, with the third glass portion between the first and the second, where the first, second, and third glass portions are configured in spaced relation from each other. The third glass portion is substantially parallel to the first glass portion. A light source emits light into the third glass portion via an edge of the third glass portion. Light-scattering structures scatter at least a portion of the light emitted by the light source into the third glass portion in a direction substantially perpendicular to a primary face of the third glass portion.

The present invention includes a pane unit (1), which comprises a frame structure (2), an illuminable pane (4), a lighting element (5), and a receptacle (8) therefor, wherein a homogeneous light field is generated by the lighting, with, e.g. the lighting element (5), of at least one narrow side (7) of the illuminable pane (4).

A curtain wall having a frame construction with a plurality of glass elements and optionally panels arranged at a distance from each other in the heat flow direction, wherein a multifunctional glass element is arranged on the room side behind the main heat-insulating plane of the curtain wall, wherein the position of the multifunctional glass element can be modified in the vertical direction and/or the horizontal direction and the multifunctional glass element has at least two of the functions from the list comprising (A) anti-glare protection in the form of modifiable or switchable layers, (B) heating capacity at least in sections, (C) a configuration with integrated LEDs as room lighting, (D) a configuration as an information system, particularly as a screen, at least in sections, (E) a configuration with at least one integrated camera, and (F) a configuration with at least one integrated loudspeaker.

A light transmitting panel assembly includes a first panel, a second panel, a frame, a gap between the first panel and the second panel, and a first active component located between the first panel and the second panel.

An insulating glass unit (10) is formed from a plurality of transparent layers (16, 18, 20), in which at least one illuminable panel (20) is arranged between at least two mineral glass panels (16, 18). The mineral glass panels (16, 18) are held at a defined distance from one another by at least one spacer element (14). The illuminable panel (20) is held at least on one longitudinal marginal edge (24) by the spacer element (14). The spacer element (14) is formed by at least one hollow profile (15), which preferably comprises a plurality of adjoining hollow chambers (26, 28). The outer mineral glass panels (16, 18) each adjoins at least two lateral surfaces of the hollow profile (15). The illuminable panel (20) rests on or against the intermediate hollow chamber (28). An illumination element (32) is arranged within the intermediate hollow chamber (28).

A spacer for a multi-pane insulating glazing unit includes a spacer body made from a first material with first and second hollow desiccant chambers extending in a longitudinal direction and a longitudinal groove between the first and second chambers open to a first side of the spacer for holding an intermediate pane of the glazing unit, the groove being delimited in a width direction by first and second side walls and having a bottom wall, and the spacer body having a gas barrier on a second side opposite the first side. The first side wall and/or the second side wall and/or the bottom wall of the groove include at least two electrically conductive portions electrically isolated from each other and configured to make electrical contact with at least one electrical contact of the intermediate pane.
