Definitions

  • the present invention relates to a self-illuminating spacer for insulating glass units, especially but not only suitable for insulating glass units used in emergency exits.
  • DE 200 16 616 Ul describes an insulating glass unit (IGU) with a metal spacer frame, which is to be used, for example, in emergency exits, suitable especially in case of a complete failure of all (other) light sources at the emergency exits.
  • the spacer frame of the multipane IGU is provided with a luminescing material such that the spacer frame at the edges of the panes is luminescing and afterglowing at its side facing the interior space between the panes.
  • DE 200 16 616 Ul teaches to either provide self-illuminating foils or to coat the spacer frame with self-illuminating paint or to use a self-illuminating emaille.
  • DE 103 22 561 Al discloses an IGU with a spacer frame hermetically sealing the interspace between the panes and usually filled with a rare gas.
  • DE 103 22 561 Al discloses three different possibilities of providing illuminating properties to the spacer frame, namely electroluminescence strips (EL), LED strips and self-illuminating strips. These long-self- illuminating strips could be phosphor pigments which are embedded in a polymer matrix and are applied with usual coating technologies.
  • EL electroluminescence strips
  • LED strips LED strips
  • self-illuminating strips These long-self- illuminating strips could be phosphor pigments which are embedded in a polymer matrix and are applied with usual coating technologies.
  • WO 2012/017351 Al discloses the use of phosphorescent material in the interspace of an IGU to enable lighting at night.
  • GB 2 405 417 A discloses the use of phosphorescent pigments with added doping substances embedded in a synthetic foil, which is applied to a surface of an element like a door frame or window frame.
  • DE 103 22 561 Al discloses a glazing element with a lighting frame, which comprises an aluminium spacer frame with a chamber for desiccating material having an inner wall with openings for allowing gas exchange with a gas filled interspace between window panes of the glazing element, the inner wall being coated with a luminating layer on its side facing the interspace.
  • the luminating layer is applied by painting or spraying or dip coating or printing or applying an adhesive foil.
  • WO 2014/063801 Al discloses a standard metal-plastic composite spacer.
  • EP 0 721 007 Al discloses a phosphorescent synthetic resin material which can be used to manufacture zippers.

  • phosphorescent materials are contained in the plastic spacer body.
  • the phosphorescent materials are not only applied to a surface of a spacer wall by coating or attaching a strip with such materials as in the prior art but are contained in the plastic material of a spacer body wall.
  • the phosphorescent materials are distributed in the material of at least the major part of the self-illuminating wall and thus the longest possible lifetime of phosphorescent materials is secured. Peeling off, scratching, handling problems at the time of cutting spacers, etc. are prevented.
  • the provision in at least the major part of the self-illuminating wall helps avoiding problems with other functions of a spacer like gas communication with the interspace between the glazing panes.
  • the integrated solution is superior to a subsequent treatment (coating or strip application) of the spacer to provide phosphorescent properties and delivers a ready-to-use solution simplifying processes in the later handling of the spacers in manufacturing insulating glass units, door, window and facade elements.
  • Etching of one or more glazing panes and/or silkscreens on one or more glazing panes of an IGU allow to add communication like signs or texts visible in case of emergency or other situations suitable for or demanding communication. Further features and advantages will become apparent from the descriptions of embodiments referring to the drawings, which show:
  • Fig. 1 a partial perspective cross-sectional view of an insulating glazing unit with a spacer
  • Fig. 2 a side view, partially cut away, of a spacer frame bent from a spacer profile
  • Fig. 3 a cross-sectional view of a spacer perpendicular to its longitudinal direction
  • Fig. 4 images of emergency exits in lighted and dark surroundings with and without self- illuminating spacers.
  • Luminescence is spontaneous emission of light by a substance not resulting from heat.
  • Photoluminescence is light emission from any form of matter after the absorption of photons (electromagnetic radiation). Fluorescence is the spontaneous emission of light by a substance shortly after that material has absorbed photons (electromagnetic radiation). It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. Fluorescent materials cease to glow nearly immediately when the radiation source stops.
  • Phosphorescence is a type of
  • a phosphorescent material does not immediately re-emit the radiation it absorbs.
  • the slower time scales of the re- emission are associated with "forbidden" energy state transitions in quantum mechanics. As these transitions occur very slowly in certain materials, absorbed radiation is re-emitted at a lower intensity for up to several hours after the original excitation.
  • Fig. 1 shows a partial perspective view of an insulating glazing unit (IGU) 40 with a spacer 50.
  • the IGU 40 comprises two glazing panes 51, 52 arranged parallel to each other with a predetermined distance between the same.
  • a spacer 50 extends in a longitudinal direction z along the edges of the glazing panes 51, 52.
  • the spacer 50 is used to form a spacer frame, e. g. by cold-bending the spacer profile into a frame shape and connecting the ends with a linear connector 54 as known in the art.
  • a spacer frame like cutting linear pieces of spacer frame parts and connecting the same via edge connectors are also possible as known in the art.
  • the spacer 50 is mounted at the edges of the two spaced glazing panes 51, 52.
  • the spacer 50 comprises side walls formed as attachment bases to be adhered with the inner sides of the glazing panes 51, 52 using an adhesive material (primary sealing compound) 61, e.g., a butyl sealing compound based upon polyisobutylene.
  • the intervening space 53 between the glazing panes is thus defined by the two glazing panes 51, 52 and the spacer profile 50.
  • the inner side of the spacer profile 50 faces the intervening space 53 between the glazing panes 51, 52.
  • a mechanically stabilizing sealing material (secondary sealing compound) 62 for example based upon polysulfide, polyurethane or silicon, is introduced into the remaining, empty space between the inner sides of the window panes in order to fill the empty space.
  • This sealing compound also protects a diffusion barrier layer provided at least on the outer side of the spacer.
  • the interspace 53 is usually filled with a gas having good heat insulating characteristics like a rare gas such as argon or xenon.
  • a gas filled interspace 53 is present between the glazing panes 51, 52 and the spacer 50 in the mounted state.
  • the spacer 50 comprises a spacer profile body 10 made by extrusion of polypropylene.
  • the profile body 10 comprises two side walls 11, 12 that are separated by a distance in the traverse (width) direction x and that extend essentially in the height direction y.
  • the side walls 11, 12 are connected via an inner wall 14.
  • a one-piece diffusion barrier film 30 is formed on the outer side of the spacer which faces away from the gas filled interspace and the side walls 11, 12.
  • An outer wall 13 may optionally be formed on the outer side of the spacer which faces away from the gas filled interspace and the diffusion barrier film 30 may be formed on the outer wall 13 as shown in Fig. 1 and 3.
  • a chamber 20 is formed for accommodating hygroscopic (desiccating) material.
  • the chamber 20 is defined in cross-sectional view perpendicular to the longitudinal direction z by on its respective lateral sides the side walls 11, 12 and on its side facing the interspace 53 by the inner wall 14. Openings 15 are formed in the inner wall 14 (see Fig. 1), so that the inner wall 14 is not formed to be diffusion-proof allowing gas exchange between the gas filled interspace 53 and the chamber 20.
  • the side walls 11, 12 are formed as attachment bases for attachment to the inner sides of the glazing panes.
  • the spacer profile is preferably adhered to the respective inner sides of the glazing panes via these attachment bases (see Fig. 1).
  • the plastic body 10 extending in the longitudinal direction z with the two lateral side walls 11, 12 adapted to face the glazing panes 51, 52 in the width direction x perpendicular to the longitudinal direction z comprises the inner wall 14 adapted to face the gas filled interspace 53 in the mounted state of the spacer formed such that its major part l4m is made of plastic material containing phosphorescent additives. Therefore the inner wall 14 is a self- illuminating wall.
  • Major part of the inner wall means in this text at least half of the inner wall in its extension in the width direction x. Containing means in this text that the phosphorescent materials are distributed in the material of the major part of the self-illuminating wall.
  • the phosphorescent material is extruded together with the plastic material of the major part of the inner wall resulting in that they are distributed in the material of the major part of the (self-illuminating) inner wall.
  • the phosphorescent materials can, of course, be additionally contained in other parts of the plastic body of the spacer, too, if wished or required.
  • an improved spacer for IGUs made of plastic material is provided with self-illuminating properties.
  • Self-illuminating property means an illumination without external energy source such as a current supply, a battery or the like.
  • the commercially available phosphorescent additive 50076 LUMILUX® Effect-MB green available from Honeywell Specialty Materials Performance Products, Seelze, Germany has been used (see https ://www.honeywell- lumilux. com/product/50076-2/). It has been extruded together with the plastic material polypropylene (PP) in an amount of 20 wt% of the phosphorescent additive.
  • PP polypropylene
  • Another possible phosphorescent additive is 50077 LUMILUX® Effect-MB green. They can be used together with PP or the plastic materials SAN (Styrene acrylonitrile) or PA
  • Polyamide or any other suitable plastic material, with or without additives like e.g. glass fibres, in an amount l0wt% to 60wt%.
  • Pig. 4 shows emergency exits. An emergency exit with the legally required green light is shown in a normal illuminated surrounding in the upper part of Pig. 4 on the left side. The same emergency exit is shown in Pig. 4 in the bottom part on the left side in a dark environment. Only the green light is clearly visible.
  • An emergency exit with the legally required green light and with a self-illuminated spacer according to the above teachings in the IGU of the emergency exit door is shown in a normal illuminated surrounding in the upper part of Fig. 4 on the right side.
  • One glazing pane of the IGU is provided with an arrow-shaped etching.
  • the arrow-shaped etching scatters the green light emitted by the self-illuminated spacer and thus improves the marking of the emergency exit.
  • the same emergency exit is shown in Fig. 4 in the bottom part on the right side in a dark environment. It is obvious that not only the green light is clearly visible but also the self- illuminated spacer and the arrow-shaped etching.
  • etching of the glazing pane or a silk-screen could be used to add signs or texts to an emergency exit, which are illuminated by the self-illuminating spacer in a dark environment.
