Description

The proposed utility model relates to furniture production, namely to furniture products equipped with a lighting device.

Currently promising is the development of designs of furniture with backlighting, equipped with various lighting devices.

So, for example, an element of kitchen equipment is known, described in the application for invention No. 2005102070 (RU), 07.24.2003, F21V 33/00, “Element of kitchen equipment”. In accordance with the description given in this application, the element of kitchen equipment shines, actively or passively, through the use of LEDs, light guides, planar discharge lamps or phosphors. An element of kitchen equipment may be a wall, door, shelf, or other element of furniture design. The use of LEDs, light guides, planar discharge lamps or phosphors in the design of an element of kitchen equipment allows you to create kitchen equipment with lighting, improves the consumer qualities of kitchen equipment, provides ease of use and allows you to create original decorative effects in accordance with the aesthetic needs of the user.

Also known is the furniture part described in the patent for utility model No. 41963 (RU), 03/01/2004, А47В 65/00, "Furniture side wall with illumination for residential premises." The furniture side wall is a L-shaped shelf partition with luminaires built into it, on the back side. The use of such a side wall in furniture design allows you to create furniture items, such as a wall furniture or cabinet display cabinet, which have the illumination of the far part of the interior of the furniture.

A known piece of furniture with a light device described in the certificate for utility model No. 34327 (RU), 07/16/2003, A47 B 13/00, A47B 96/00, "The piece of furniture with a light device." A piece of furniture with a lighting device is characterized in that the LEDs used in it are located in the piece of furniture in such a way that their face faces the end part of the plate structural element of transparent material. For example, LEDs can be placed on the inside of the door frame with glass. At the same time, the door is illuminated around the perimeter and an original decorative effect is created.

From foreign sources, a number of devices and parts of furniture are known to provide furniture lighting. In particular, a lighting device mounted on furniture, DE3832860 (A1), 04/20/1989, А47В 96/00, А47В 97/00, F21S 3/02, F21S 8/00, F21V 5/02, F21V 7/12, F21V 7/18, F21V 14/04, F21V 17/02, F21V 21/096, F21V 21/14, F21V 21/30, F21V 23/04, F21V 33/00, "Furniture with an attached lamp." Furniture part, DE 10311492 (B3), December 16, 2004, А47В 97/00, F21S 4/00, F21V 33/00, “End metal strip with LEDs placed in it, attached to the shelf and illuminating it on both sides”. Furniture panel, US2001036070 (A1), 11/01/2001, A47B 77/00, A47B 97/00, F21S 2/00, F21V 23/06, F21V 33/00, "Luminous modular panel for modular kitchen furniture." Cabinet, JP5137626 (A), 06/01/1993, A47B 96/00, A47F 11/06, F21V 8/00, G02B 6/00, “Cabinet design with decorative backlight function”.

All the above examples have a common feature - the use of light sources in furniture design is assumed at the stage of furniture design. To install light sources in a piece of furniture or its element, the latter provides technological cavities, recesses, holes, etc. The sizes of furniture elements are selected taking into account the sizes of light sources (and vice versa). The furniture design includes channels for laying conductors, heat removal systems and the like technological solutions. In some cases, the light source and the furniture element are combined in such a way that the combination of the furniture element and the light source is a single unit. In an effort to preserve the uniqueness of their products, furniture manufacturers try to avoid the use of element sizes, types of processing and decoration that are common with other manufacturers. All this makes it difficult or impossible to use the elements of one piece of furniture in the design of another piece of furniture. The above common feature is non-universality, which can be considered a lack of backlit furniture elements.

At the same time, an illuminated piece of furniture is described in the utility model certificate No. 34328 (RU), 07/16/2003, А47В 13/00, А47В 96/00, "Illuminated piece of furniture." This illuminated piece of furniture is selected as a prototype and represents a panel forming a structural element of a piece of furniture, the panel containing a mounting plate with light-emitting elements (LEDs) placed on it and a plate made of transparent material located on top of the mounting plate.

A piece of furniture, in particular a shelf, contains supporting walls 1, between which a standard furniture panel 2, which is a shelf, is placed. In a standard furniture panel 2, a work was made in which a light device made in the form of a panel was placed, including a mounting plate 3, on which a matrix of LEDs 4 was placed, and also a plate 5 located on top of the board 3, made of a transparent material, for example, glass. The LEDs 4 are electrically connected to each other and included in an electric circuit for supplying power to them, containing a control and power unit 6, electric wires 7, a switch 8 and a plug 9 for connecting the electric circuit to the electric network (the numbering of the parts indicated in this paragraph corresponds to numbering of parts of a piece of furniture with lighting, described in the certificate for utility model No. 34328 (RU), 07/16/2003, A47B 13/00, A47B 96/00, “A piece of furniture with lighting”).

Due to the use of LEDs in the design of the lighting device, during operation of which a significant amount of heat is not released, the furniture component does not heat up. The lighting device can be installed in a specially designed furniture panel at the production stage or integrated into a standard furniture panel by making a development in a standard furniture panel and placing a pallet in it with a light device installed in it. The use of such a panel in the construction of furniture improves the consumer properties of the piece of furniture due to the presence of illumination, while the lighting device simultaneously creates an interesting decorative effect.

The disadvantage of the prototype is that the use of such a technical solution allows lighting only in the interior space of a piece of furniture adjacent directly to the front of the light device. In the case when it is necessary to illuminate the area of the interior space of a piece of furniture located on the back side of the lighting device, it is necessary to install an additional lighting device. One prototype lighting device illuminates only one area and only the interior space of a piece of furniture.

The objective of the claimed utility model is to create a lighting structural element of furniture? able to illuminate the space on both sides of the plane of the longitudinal section of the furniture element. At the same time, the illuminating structural element of furniture should be applicable both for the design and production of new pieces of furniture and equipment, as well as in the remaking of existing pieces of furniture and equipment.

The problem is solved by placing the light device in the cavity through holes of the furniture panel (structural element of furniture). A through hole can be made at the time of production of a structural element of furniture or made in an already manufactured piece of furniture. The through hole made for mounting the lighting device may have any geometric shape in accordance with the artistic design of the manufacturer. In this case, the structural element of the furniture may have one or more through holes for accommodating lighting devices. The lighting device is made using LEDs, which are located on both sides of the circuit board, located in the formed hole, made in the structural element of the furniture. Also, the lighting device can be made in the form of alternating rows (rulers) of LEDs, while the LEDs are turned on even lines in one direction, and on odd ones in the opposite direction. In addition, the lighting device can be formed by several rows (lines) of LEDs located on the faces formed by a through hole made in the structural element of the furniture. In this case, the LED lines are preferably mounted on a strip of heat-conducting material attached to the faces or attached to the faces of the through hole using a heat-conducting adhesive that removes excess heat from the LEDs. On both sides of the formed hole is closed with plates of transparent material, while the plates of transparent material correspond to the size of the structural element of the furniture. In this case, one or more faces of the plates of transparent material can be polished and may have a chamfer to improve the consumer qualities of the product. On the surface of the plates decorative coatings, patterns, patterns, etc. can be applied. Also, the surface of the plates of a transparent material can be subjected to chemical etching or sandblasting, as a result of which a layer is formed on the surface of the plates that changes the refraction, reflection and penetration of light rays. Depending on the type of light device used, a light filter or other object fulfilling its role, for example, a container with liquid, can be placed directly into the light device or in the immediate vicinity of the through hole. At the same time, one of the plates, for example, located on the outside of a piece of furniture, can exceed the size of a piece of furniture with its dimensions, go beyond it (depending on the artistic design) or close through holes in several pieces of furniture at once, thus combining several similar items of furniture. The light device is connected via a conductor to the control unit of the lighting device and further to the mains. To control the brightness of the LEDs, their flashing frequency, color change of the light flux and other characteristics of the light device, additional electrical devices can be included in the electrical circuit of the light device, such as a dimmer that allows you to change the brightness of the LEDs, a controller that allows you to change the frequency of changes in brightness and color LEDs (for RGB LEDs) and cycle rate, matching device (control signal amplifier) allowing board a large number of LEDs, controller and dimmer control unit and a switch selection controller and dimmer control modes. Also, to improve the consumer properties of the lighting structural element of furniture, the receiving antenna unit of the radio-frequency or infrared range, depending on the type of control channel, and a remote control panel for selecting controller and dimmer operating modes in the corresponding range can be additionally included in the electrical circuit of the control unit.

Features of the claimed utility model are that:

- the lighting device built into the structural element of the furniture is not autonomous, but forms the illuminating structural element of furniture;

- lighting structural element of furniture can be made in the manufacture of furniture and be part of a new piece of furniture;

- the lighting structural element of furniture can be made of an existing structural element of furniture, even for a piece of furniture in use, without an unacceptable deterioration in the strength characteristics of the structural element of furniture;

- illuminating the structural element of furniture illuminates the space on both sides of the plane of the longitudinal section.

- the illuminating structural element of the furniture does not heat up, due to the use of LEDs as light sources in it, during operation of which there is no significant heat generation;

- the illuminating structural element of furniture can form a table top, shelf, wall, bottom or cover of a rack or cabinet or any other structural element of a piece of furniture.

The advantage of the claimed utility model is to improve the consumer properties of furniture due to the fact that there is a simultaneous uniform illumination of the interior spaces of the furniture on both sides of the illuminating structural element of the furniture, as well as simultaneous uniform illumination of the interior of the furniture and the space outside the furniture adjacent to the lighting a structural element of furniture (depending on the location of the illuminating structural element in a piece of furniture).

A plate of transparent material 11, can be fixed on the bottom of the hinged kitchen cabinet (bottom) 3, using adhesive, mechanical fastening of arbitrary shape, magnetic fastening or not be fixed. From below, under the lower part of the wall cabinet (bottom) 3, there is a plate made of transparent material 12. A plate made of transparent material 12 ensures even diffusion of light coming from the LEDs 5. Also, a plate made of transparent material 12 protects the light device from possible pollution or damage. To improve the dispersion of the light flux emanating from the LEDs 5, the plate of transparent material 12 from the side facing the light element is subjected to processing that degrades the quality of its surface and creates a matte layer on the surface of the plate. The plate of transparent material 12 has dimensions corresponding to the sizes of the lower part of the hinged kitchen cabinet (bottom) 3, with tolerances that allow safe operation and easy installation.
