Description

Field of the invention

The invention relates to a presentation or Unterlegplatte of non-combustible material such as glass or the like as a lighting element for a fuel cell such as an oven, stove or the like according to the preamble of claim 1.

State of the art

Such laying or shims are known per se and are usually prescribed to fire cells for fire protection reasons. In most cases they consist of metal, stone or other non-flammable materials such as glass.

Comparable plates are used for lining of fuel cells, after which light sources (eg RGB LEDs or RGBW LEDs) are arranged on the glass plates and these are then attached to the fuel cell. The light sources bring light into the glass plates, which is radiated by appropriate light conduction in the plates of these. As a result, the entire surface of the fuel cell, in particular the convection body, to the luminous body ( DE 20 2014 006 532 U1 ).

Such LED lighting elements are also known for escape route luminaires ( DE 20 2012 100 991 U1 ), Room lighting and for use in the aerospace industry ( DE 10 2015 211 312 A1 ).

Presentation of the invention

Based on this prior art, the present invention seeks to provide an illuminable presentation or Unterlegplatte for fuel cells such as an oven, stove or the like.

This object is achieved by a presentation or Unterlegplatte with the features of claim 1. Advantageous developments are the subject of the dependent claims. The features listed individually in the claims can be combined with each other in a technologically meaningful manner and can be supplemented by explanatory facts from the description and by details from the figures, wherein further embodiments of the invention are shown.

Due to the illumination of the non-flammable, light-conducting material such as glass or the like existing laying or shim plate, which is used as a light guide, the fuel cell to the luminaire, which is available all year round and not only during the firing time. The use of the presentation or shim as a luminaire also has the advantage of being able to be used as a room lighting, so also to influence the atmosphere of the room. For this purpose, light sources such as e.g. LEDs or other bulbs used, which emit their light preferably in at least one edge of the plate. The light is reflected in the plate and diffused outwards, so that, if necessary, a uniform, full-surface illumination, but also only a lighting can be achieved only on a part of an edge or surface of the plate. It must be ensured that the light, which is preferably coupled into the edge or also by fluoroscopy, is applied at a suitable location, e.g. is radiated again on an edge or on another surface or also transversely to the longitudinal extent of the plate. At the same time, it must be ensured that this radiation is preferably uniform over the entire plate.

Advantageously, the plate surrounds the fuel cell at the bottom and / or is arranged under the fuel cell, so that additional optical effects can be achieved. At the same time the plate complies with the fire protection regulations.

Preferably, a safety glass, such as e.g. One-pane safety glass or laminated safety glass used, which is preferably relatively thin.

One-pane safety glass has increased impact and impact resistance due to the tensile stress which arises in the core as well as the compressive stress which arises in the surface in spite of its low thickness. However, if it breaks under excessive load, the toughened safety glass disintegrates into the smallest pieces without sharp edges, which greatly reduces the risk of injury.

Laminated safety glass owes its safety properties to a tear-resistant and viscoplastic film between the glass panes. By means of a roll press, a so-called "pre-bond" of two or more glass sheets lying one above the other and a film usually consisting of polyvinyl butyral (PVB) or ethylene vinyl acetate (EVA) is produced. The autoclave is then used under heat (about 140 ° C) and pressure (about 12 bar) creates a permanent bond of glass and film. Bonded safety glass binds splinters in the event of a break, thus significantly reducing the risk of injury.

Since a high temperature results when using a fuel cell such as an oven, stove or the like and this heat is usually discharged into the room, it is advantageous that the tempered glass remains insensitive to large temperature differences.

For the light pipe, the use of white glass has proven to be advantageous because this glass affects the coupled light least by inclusions.

Preferably, the light from the LEDs is coupled to at least one edge of the plate. If RGB LEDs or RGBW LEDs are used in particular, any color variations or even color gradients and brightnesses can be realized.

Conveniently, the LEDs are placed in an LED track, preferably at the trailing edge, around the and / or under the cell mounted plate, as this allows their location to be fixed and protected at the same time.

In order to achieve good visual effects, the plate is preferably designed such that the coupled-in light is radiated over the entire surface and in the direction away from the firing cell.

It is advantageous if the plate is preferably smooth on the outside, and one which has coupled-in light diffusely distributing layer. This makes it easy to clean the plate, at the same time results in a homogeneous appearing lighting. If necessary, the plate can also be deliberately structured. Depending on the design wishes of the customer, any desired effects can be achieved.

If necessary, a logo or the like can be placed on or in the plate or in the single-pane safety glass, preferably by gluing, printing, sandblasting or lasers. As a result, the advertising effectiveness of the plate can be increased.

To obtain appropriate effects or even to achieve a homogeneous appearance, the plate may preferably be coated with e.g. lasered light directors, e.g. be provided for targeted decoupling of the light. Alternatively, corresponding light-guiding elements can also be produced by gluing, printing, sandblasting or the like or else by a combination of these methods

Further advantages emerge from the dependent claims and the following description of an embodiment.

Description of preferred embodiments

Before describing the invention in detail, it should be noted that it is not limited to the respective components of the device and the respective method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not intended to be limiting. In addition, if singular or indefinite articles are used in the specification or claims, this also applies to the majority of these elements unless the overall context clearly makes otherwise clear.

1 shows a fuel cell 10 such as a stove, stove, fireplace, heating element or any other type of oven that can be used in principle for fuels of any kind. The fuel cell has a combustion chamber 11 and a convection body 12 on. The convection body 12 serves to give off heat to the ambient air.

In front of the fuel cell 10 is a presentation or a Unterlegplatte 13 (hereinafter "plate 13") made of a non-combustible material such as glass or the like. This plate 13 is in this specific case a glass plate made of safety glass. Under a serving plate is a refractory, located on the ground security plate understood that protects the ground around the fuel cell from flying sparks or falling ash. Under a shim is a fireproof, located on the ground security plate on which stands the fuel cell and protects the soil around the fuel cell. Such a plate 13 is by using light sources 14 Such as LEDs, especially RGB LEDs or RGBW LEDs, but also illuminated by other bulbs, making the plate can be a filament and not only in the cold season, but throughout the year. In this case, the light can preferably vary in color, brightness and also in the color gradient.

2 shows in a view from above a fuel cell 10 which is at least partially surrounded by a serving plate or stands on a shim.

The plate 13 in the exemplary embodiment, preferably consists of single pane safety glass (ESG) or laminated safety glass. It remains insensitive to high temperature differences and may possibly carry a heavy weight.

Single-pane safety glass consists of a single, specially heat-treated pane, the manufacturing process giving the glass increased impact and impact resistance compared to normal flat glass. For this purpose, the glass is heated to temperatures above its transformation temperature during processing and then cooled down abruptly. As a result, the outer, near-surface zones of the glass cool faster than the inner core, so that a tensile stress is generated in the core and a compressive stress in the surface. One-pane safety glass must therefore be sanded or cut to size before the heat treatment; subsequent processing is only possible to a very limited extent. In particular, machining that penetrates into the tensile stress zone of the glass may result in breakage of the disk. Alternatively, however, it is also possible to use composite safety glass with comparable properties or another non-combustible, but light-conducting material for the plate 13 ,

When using single-pane safety glass this can be used as the light guide, which is required as a light guide for the inventive use. Unless the plate 13 Light is conductive, but also another material can be used for it. In this case, the light-guiding element can be provided with light-guiding elements 19 for targeted coupling out of light. This can be achieved, for example, by lasering, gluing, printing, sandblasting or other suitable treatment of the surface.

If single-pane safety glass is lasered, the surface of the laser is partially heated, thereby the light guide elements 19 train. It must be ensured that the tension zone of the single-pane safety glass is not reached as far as possible during lasering, which would increase the risk of breakage.

Preferably, white glass, in particular as single-pane safety glass or laminated safety glass, is used, since this glass affects the coupled light least by inclusions. In principle, however, other glasses can be used.

According to 3 become light sources for lighting 14 , preferably LEDs and in particular RGB LEDs provided. Through these light sources 14 which in a rail 15 are arranged, the light is at least one edge, preferably at the trailing edge, on the ground 18 lying plate 13 coupled to the and / or under the fuel cell 10 is arranged. That in the plate 13 coupled light 16 would now be in the plate 13 as in a light guide propagate, ie a radiation across the light guide would not take place. But like the rays 17 . 20 clarify, the plate radiates 13 the light in a direction away from the fuel cell 10 from. For this purpose, preferably has the outside smooth or structured as desired plate 13 preferably a lying in or on her body, the coupled-in light 16 diffusely distributing layer. Basically, the plate needs 13 not smooth on its outside, it can be structured there in any way or have a putzartiges appearance.

In a manner not shown in the drawing, logos or other markings may be attached to the plate. These markings, logos, but also the light directing elements are preferably lasered, i. they are lasered elements. In principle, however, they can also be applied or applied by gluing, printing, sandblasting or other suitable treatment measures.
