Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1a shows a chromaticity diagram of the CIExyY colour space.

(2) FIG. 1b shows an enlarged detail from FIG. 1a.

(3) FIG. 2 is a schematic diagram of an embodiment of a fitout article or article of equipment of the disclosure in cross section.

DETAILED DESCRIPTION

(4) FIG. 1a and FIG. 1b show chromaticity diagrams of the CIExyY colour space with 2° standard observer (CIExyY-2°). FIG. 1b shows an enlarged detail of the overall region of the chromaticity diagram shown in FIG. 1a.

(5) The figures depict the black-body curve as a dotted line, the two white regions W1 and W2 as dashed lines, the colour coordinates of the examples that are listed in the tables and are suitable for use in an article of the invention as black squares, and examples from the prior art as black crosses.

(6) Every point on the black-body curve corresponds to the colour locus of the light emitted by a black-body radiator at a defined temperature, called the colour temperature. This curve is of particular relevance to human perception since the sun likewise corresponds to a black-body radiator and hence the colour of sunlight is on the black-body curve. According to the position of the sun, the colour locus moves between cooler and warmer colour loci; a colour temperature of 20 000 K corresponds to a clear sky and a temperature of 3500 K to evening sunlight shortly before the commencement of dusk. Colour loci at or close to the black-body curve are therefore perceived as white and particularly natural.

(7) The prior art described consists partly of the glass ceramic types specified in WO 2012076414 A1 and partly of commercially available glass ceramics from SCHOTT AG and Eurokera. These examples from the prior art are all outside the white region W1. As known from WO 2012076414 A1, the white region W1 can be covered by these glass ceramics only through the use of additional, complex compensation filters. However, the inventive examples cover this region even without such a filter. All the colour loci shown relate to a material thickness of 4 mm.

(8) The examples adopted from Tables 2, 4, 5, 6 and 7 are all within the white region W1. Among these, all examples that contain less than 0.01% by weight of V2O5 in the glass ceramic, i.e. including the coating examples from Table 5 that have been applied to V2O5-free glass ceramics, are also within the white region W2. In addition, the V2O5-free glass ceramics from Tables 2 and 4 are also within the white region W3 (not shown).

(9) FIG. 2 contains a schematic illustration of an article of the invention in cross section. The fitout article or article of equipment (1) shown for a kitchen or laboratory comprises a display device (2) and a separating element (3) that divides sections of an interior (4) of the article (1) from an exterior (5). The display device (2) is disposed in the interior (4) of the article (1) such that the light emitted by the display device (2) passes through a section of the separating element (3) and is perceptible by a user in the exterior (5) of the article (1). In the embodiment shown, the separating element (3) consists of a glass or glass ceramic substrate having a coefficient of thermal expansion CTE of −6×10−6/K to 6×10−6/K in the temperature range between 20° C. and 300° C. A covering means (6) disposed on the side of the separating element (3) facing the interior (4) of the article (1) has a light transmittance of at most 7% and has a cutout (8) in the region of the display device (2). The separating element (3) in the region of this cutout (8) has a light transmittance of at least 5% and of at most 70%. The covering means (6) has a colour locus in the CIELAB colour space having the coordinates L* of 20 to 40, a* of −6 to 6 and b* of −6 to 6. The colour locus of the D65 standard illuminant light after passing through the glass or glass ceramic substrate of the separating element (3) in the region of the cutout (8) of the covering means (6) is within the white region W1.

(10) Fitout articles or articles of equipment of the invention for kitchens or laboratories may also contain a multitude of further components in their interior in addition to the display device.

(11) The articles may, for example, have one or more heating elements for heating an article, for example a pan, in the exterior or even in the interior of the article. These may especially be radiative heating elements, induction heating elements, gas heating elements or microwave generators.

(12) The articles may have further display devices and other lighting elements such as point, linear or areal light sources. These include, for example, LEDs, optical fibres and OLEDs. These light sources can emit in a particular colour, especially white, red, green and/or blue, or else variable colours. Between these display devices or lighting elements and the separating element, it is also possible for additional colour filters to be provided, for example in order to be able to utilize a white LED for production of a coloured lighting effect with a defined colour locus and high colour saturation.

(13) Further display devices that may be provided may be either segment displays or graphic displays. The segment displays may especially be designed as coloured 7-segment displays. The graphic displays are preferably TFT displays, for example LCDs or OLED displays.

(14) Lighting elements may especially also be disposed in the hot region in the vicinity of heating elements. In this case, especially for the production of white lighting effects in the exterior of the article, it is advantageous that no temperature-sensitive black-body compensation filters are required.

(15) In a preferred embodiment, in addition to a lighting element, one or more scattering or diffuser layers may be provided. Preferably, such layers are used in combination with at least one covering layer between substrate and lighting element and with at least one cutout in the covering layer. Scattering and diffuser layers can especially be used to produce a homogeneous lighting effect of linear and areal lighting elements.

(16) Scattering and diffuser layers may optionally also be executed in coloured form. Coloured scattering and diffuser layers may simultaneously function as diffuser and as optical filter.

(17) Such scattering or diffuser layers may have a thickness of 1 to 15 μm, for example. They may contain non-coloured scattering particles, for example of TiO2, SiO2, Al2O3, ZrO2 or other metal oxides. The average size of such particles may be less than 1 μm. Preferably, the scattering or diffuser layers have high homogeneity of the luminance produced, low granularity and high brightness. This results in a perception of a very homogeneously lit area which is very pleasing to the user.

(18) The articles may have cooling aggregates, for example Peltier elements, in thermal contact with the separating element in order to produce a cooling surface, for example for cooling of foods or chemicals, on the exterior-facing side of the separating element.

(19) The article may have various sensors, for example capacitative touch sensors for control or infrared sensors for gesture control or for measurement of the temperature of hot articles in the exterior, for example hot pans. In addition, the article may have microphones and cameras, for example for voice control or user recognition and authentication. This may be particularly advantageous in laboratories, for example, if the article may be used only by correspondingly trained personnel. Such sensors may have been printed, pressed, bonded or adhesive-bonded, or arranged in some other way, on the inside of the separating element. This is particularly true of touch sensors.

(20) The article may have various interfaces for communication, for example WLAN, Bluetooth or NFC modules or infrared interfaces. By means of such interfaces, the article can be connected, for example, either to the Internet or to other articles in its vicinity, for example pans with a corresponding interface or other electronic devices. More particularly, for control and communication, it can be connected to a mobile electronic device, such as a mobile phone or a tablet.

(21) The article may contain a device for wireless energy transmission from articles in the exterior, especially by means of induction coils and in accordance with the Qi standard.

(22) The separating element may have coatings on the exterior-facing side, for example anti-scratch layers, anti-reflection layers, anti-glare layers, decorative layers, easily cleanable layers or infrared-reflecting layers, provided that these do not alter the essential optical properties of the separating element.

(23) The separating element may have cutouts, for example recesses for sinks or down-draft fume hoods or bushings for pipelines.

(24) Likewise optionally, the separating element may have edge elaboration, for example a facet or a pencil finish.

(25) All these constituents may be present individually or in combination.
