Abstract

The invention relates to illuminated furniture fronts in all segments of room furnishing, such as for bathroom, kitchen, bedroom, living room, nursery, and youth bedroom or hallway furniture, for the purpose of increasing living comfort. The aim of the invention is to provide a solution for illuminating furnishings and other applications across the front surfaces or visible surfaces thereof in such a way that preferably no shading is produced in the edge areas due to frame designs and the illumination is uniformly intense across a furniture front. Said aim is achieved by means of illuminated furniture fronts (1) having a layered construction, in particular on surfaces facing an observer, of furnishings and on other structures of interior architecture, such as in connection with tabletops, integrated in room ceilings as a hanging lamp, light plate etc., characterized in that the layered structure comprises translucent and non-translucent plate-shaped materials, the translucent plate-shaped materials having a small thickness, wherein a borderless layering of a translucent outer front plate (2), an LED light panel (4), and a non-translucent carrier plate (7) is provided, the non-translucent carrier plate being made of plastic, metal, or wood, and wherein the side edges of the translucent surfaces lying one over the other are fastened by attaching an edge band (8) and this composite, which is rigidly attached to the carrier plate, has a scratch- and impact-resistant film (3) of a furniture pattern or another visual representation in front of the front plate (2), which film can be illuminated through the front plate (2) from the inside out by means of the lighting means, the LEDs (5), arranged in the LED light panel (4).

Description

Illuminated furniture fronts

The invention relates to illuminated furniture fronts in all segments of the interior design, such as bathroom, kitchen, bedroom, living room, children's and Jugendzimmer- or hallway furniture for the purpose of increasing the living comfort, which means of an indirect or direct-acting lighting a more remote or immediate environment at the location of such equipped furniture is achieved.

However, according to the principle of illuminated furniture fronts, table tops, underhang lamps, light panels, light displays and light pictures are also conceivable in two- or three-dimensional constructions, in particular in interior design.

The indirect light for the environment providing lighting of sideboards, showcases u. a. has long been known and it is carried out by shielded incandescent lamps, fluorescent tubes and, increasingly, by low-power consuming LED in practice.

However, a direct directed into the surface of a furniture front lighting is not yet or only inadequate quality achieved. With reference to the state of the art set out below, reference should be made, by way of example, to solutions which devote themselves to surface illumination with more or less success.

For example, DE 20 2007 015 538 U1 discloses furniture lighting for glass panels. It carries a U-profile in its interior and between its outer cheeks a cold cathode as a light source and it corresponds to the distance between the two edges of the U-profile of the strength of a glass plate on which the U-profile is pushed. This illuminates the edge of the glass plate, from which the light is further distributed in the uncovered area of the glass plate.

The disadvantage here is the partial coverage of a usable as a shelf glass plate.

According to WO 2009/105 644 A1, a frontal illumination of a surface has been proposed by means of an LED illumination built up in front of the surface. By positioned in several rows on a web LED ^'s for both the center and the upper and lower edge region can be illuminated effectively.

The disadvantage, however, is the separation of the light source from the surface to be illuminated, resulting in no suitability for lighting in furniture.

The solution in DE 25 1 1 030 A1 offers a lighting fixture, in particular for (a) refracting surface lighting. The lighting fixture here is made of transparent material, so that light can escape from its interior, whereby at one edge of the Lighting body is attached to a light source, which conducts light in the surface by continued reflection of the light on the opposite sides of the glass, which is reinforced by straight grooves, so-called impurities on the surface of the lighting fixture. The rectilinear impurities change their distance from each other with increasing distance from the light source. The disadvantage here may be that is lost when depositing dust particles in the impurities, the effect of large-scale light distribution.

In DE 10 2008 025 475 A1, a programmable furniture lighting has become known, according to which individually controllable lighting systems are mounted in a sideboard in each of its individual areas. Here, the interior of a furniture body is illuminated selectively or as a whole and front panels are not provided.

A similar "open" variant of the illumination of the interior of a furniture ^carcass' or shelf portion lends itself to DE 20 2007 002 463 111th Here, a metal bracket is shaped so that it can support a luminous means by hanging on the one hand in an open to closed area, and has at its opposite end such an angling which allows it to be inserted into a bore for holding pins of a shelf A deployed clamping action keeps the holder in position.

These examples have shown that there are a number of ways to technically equip furniture via their specially designed surfaces both in closed form and in open form by attaching lighting means such that their appearance in the furnishing of living space can be very individual. However, it is not always achievable that interfering auxiliary structures (frame formations) do not affect the propagation of the installed light.

It is therefore an object of the invention to propose a solution for lighting of furniture and other uses of the type mentioned above the front or visible surfaces, so that no shading in the border areas arise as possible by frame structures, the lighting is uniformly intense over a furniture front, so It should also be possible by means of translucent films, which may be mounted in front of or behind translucent materials, made of appropriate plastics or glass, furniture decors, two-dimensional pattern, images, etc. without loss of quality in the representability and above all borderless. The production of constructed in this way surfaces for illuminated furniture fronts should also be inexpensive and their supply of electrical energy using integrated LED bulbs cost. The basic solution of the problem is carried out according to the characterizing features of claim 1.

The further embodiment of the invention is made according to the claims 1 to 2 following claims.

Further references to the teaching of the invention are required.

An illuminated front of the furniture basically consists in its layered structure of a front panel, an LED light panel also called a light guide plate and a support plate, the latter is non-translucent, where it is, for example. Plastic or wood and contributes due to their rigidity to the stability of the connection system. The front panel has translucent properties, which is an organic synthetic or silicate glass. Behind or in front of the front panel is a printed film with a furniture decor or another example. Individually selectable representation of a composite by several furniture fronts image or a natural substance model, for example, stone grains where this film that of the recessed on the edge of the LED light panel LED generated light can pass out to the surface of the front panel. The film and the front panels adhere to each other over the entire surface, so that even the minimal heat input of the LED on the LED light panel does not cause any distortion or blistering. In addition, it can be provided that a cooling surface made of heat-dissipating material is mounted behind the LED light panel.

The front panel, the printed film and the LED Lichtpaneel are translucent, the latter is preferably made of acrylic glass (PMMA) and at one or more edges, the LED are, are firmly connected to a total of a rear rigid support plate by their common Edges, an edging is glued or wedged as edges around a thin strip of wood, plastic or metal. The thus created composite system of several translucent and an opaque plate can be provided by the variably predictable thickness of the support plate for both supporting and non-supporting functions on furniture carcasses.

The support plate is usually made of metal z. As aluminum, wood, plastic (opaque) or it is made of the material of a furniture chipboard, wherein the bonding of the support plate with the aforementioned light-generating and lichtverbreitenden elements does not exceed the material thickness used in the furniture industry furniture board of 19 mm.

Incidentally, the carrier plate allows its rear side facing a furniture carcass that recesses for furniture hinges can be worked out there in the required manner. The invention will be explained in more detail with reference to an embodiment. Reference is made to the drawings of Figures 1 and 2.

Show it:

FIG. 1: a sectional view of an illuminated furniture front FIG. 2: a perspective front view according to FIG. 1

The structure of an illuminated furniture front 1 is clear from Figure 1. Here it can be seen that outside a translucent front panel 2, consisting of acrylic glass, a shock and scratch-resistant film 3 with a specific furniture decor or other graphic, pictorial or two-dimensional Appearance is firmly raised, this film 3 also has translucent properties, both of which are illuminated over the entire surface, from the edge, by means of an LED light panel 4 arranged behind it. The LED Lichtpaneel 4 has at least on two of its four edges lined up LED ^' s 5, their point-shaped light by means of a on the surface of the LED light panel 4 mechanically evenly deep lattice structure on the side facing forward and outward, absolutely without brightness differences in the surface of the illuminated furniture front 1 radiate. The plate-shaped elements mentioned up to here are firmly connected to a back of the illuminated furniture front 1 final support plate 7, for which purpose a the marginal areas on the side edges final and there permanently mounted enclosure, an edging edge 8, is provided. The Kantenumleimer 8 may be such a thin strip of metal, plastic or wood, that between adjacent illuminated furniture fronts 1, for example. Between drawer surfaces or between adjacent door leaves on a piece of furniture, hardly any limitations are perceived. Shadowing on the surface of an illuminated furniture front 1 can be found, as a result of a progressively more intense from the outside to the inside in the LED light panel 4 reflection of the in particular oppositely disposed LED ^'s 5, not. The LED ^' s 5 are, for example. In a version with two oppositely arranged rows, in each case one on the edge of the back of an LED light panel 4 incorporated groove. 9

According to Figure 2, the body of an illuminated furniture front 1 is shown in a perspective view, the illuminated furniture front 1 measures in depth about 6 to 50 mm and the edge band 8 - this following -. has a thickness of only 1 to 6 mm. The layered structure of film 3, a front panel 2, an LED light panel 4 with LED ^' s 5, a reflector 6 and a cooling surface 10 as essential elements of the illuminated furniture front 1 can be specified with a thickness of about 6 mm. In the example shown, the illuminated furniture front 1 in the interior behind the LED light panel 4 still has a light exit reinforcing reflector 6, which may consist of a light-reflecting metal foil.

It is conceivable that more than one LED light panel 4 is integrated into the layered structure of the illuminated Möbelfrontl.

The advantages of the inventive solution can be summarized in the following: it is possible for the first time to completely illuminate the surfaces only from the edge of the can without producing a frame of profiles or a frame support, so that unnecessary shadowing is avoided,

the different layers are connected to each other only by the glued edges, by means of a Kantenumleimers,

By this structure, it is possible to produce very thin light surfaces, which u. a. easy to connect to conventional furniture boards in furniture manufacturing

the illuminated furniture front is both for decorative purposes and as well as for homogeneous lighting surfaces for direct lighting of z. B. work surfaces (kitchen furniture) can be used,

- To produce a specific or changing LichtmischungAen also different colored LED can be present in the light panel.
