Description

 CEILING LIGHTING SYSTEM

Technical field

 The invention relates to the field of construction, in particular to suspended ceilings, namely to ceiling lighting systems.

 False ceiling is a design with a special way of installation. It is suspended from the main ceiling. Such a decision in interior design is very popular recently.

 The suspended ceiling consists of a frame (slats and fixtures) and plates, which determine the appearance, type, color, and relief of the structure. Behind these plates communication, for example, electric cables, can be arranged. This greatly simplifies their maintenance and repair, and also improves the appearance of the room. In addition, the installation of suspended ceilings on the ceiling surface makes it possible to hide defects in rough finish, bumps, cracks, and prevent plaster from sprinkling. If, in conjunction with materials for creating a suspended ceiling, use insulation elements, you can significantly increase the sound insulation and thermal insulation of the room. Thus, the installation of suspended ceilings in premises for various purposes allows us to solve many problems related to both construction and interior decoration.

 Prior art

 A device for facing ceilings and walls is known, which comprises a facing material and a lighting system that is placed with the possibility of supplying a directed stream of light. The facing material has a user side and an opposite back side. The lighting system is located on the back of the cladding material, and the cladding material has a light transmission coefficient for light that is produced by the illumination system in the range of 0.5% - 30%, especially in the range of 1% -20%. [RU 2544197 C2. E04B9 / 32, 2015].

 The specified device facing the ceiling and walls performs the function of lighting (especially lighting) and the function of wall or ceiling cladding. The patent does not describe the lighting system itself.

Closest to the invention that is claimed is a suspended ceiling Armstrong, which contains a suspension system of T-profiles, attached to any ceiling base, and decorative panels installed in the cells of the frame system. Instead of any plates in the cell, you can install the built-in Armstrong square raster lamp, which is designed specifically for this and has a standard size, regardless of the light source that is used in it, [www.podvesnoi.ru/armstrong/].

 Built-in square raster lights stand out significantly from the ceiling, forming gray spots. Such lamps do not provide the opportunity to obtain the required level of lighting of the room, in particular specific workplaces or common areas. Lamps require additional heat dissipation radiators. In addition, there is some difficulty in installing such a suspended ceiling with raster lamps Armstrong.

 Disclosure of the invention

 The basis of the invention is the task of creating a ceiling lighting system in which the lamps would not stand out against the ceiling and would have improved lighting performance, comfortable for the person’s work and eyes, in which the reliability of the lighting devices of the suspended ceiling would be ensured, and at the same time, such a system was easy to install.

 The problem is solved as follows. In a ceiling lighting system comprising a frame of rigid profiles, decorative panels and fixtures according to the invention, decorative panels are placed to form a mesh structure, and in the spaces between the panels there are lamps that are made of LED strips mounted on the protruding elements of the rigid frame profiles, and which further comprise light diffusers made of polymeric materials.

 Rigid profiles are interconnected in the frame by means of expanding springs, consisting of a tongue and a notch, stamped in the profiles.

 The light diffusers on the profiles are fixed using longitudinal locks in the form of two protrusions on the inner side of the light diffuser located at its end.

 The protruding elements of the hard profiles additionally contain a polymer coating.

Rigid profiles are made in the form of T-shaped profiles. The LED strips have LEDs equidistant from each other, while the LED strips are mounted on the protruding elements of the profiles using double-sided tape or self-tapping screws.

 Light diffusers are hemispherical and made of polycarbonate.

 The rigid profile is made of metal with a thermal conductivity of 47-58 W / m * K.

 Decorative panels are made of galvanized metal with a polymer coating.

 LED strip - a light source assembled on the basis of LEDs, is a flexible printed circuit (mounting) board on which the LEDs are placed equally spaced from each other. As a rule, the length of the tape is 8-20 mm, the thickness (with LEDs) is 2-3 mm.

 A significant advantage of LEDs is:

 ease of installation;

 low cost of operation (LEDs have one of the highest indicators of the ratio of luminous flux / cost of operating costs);

 reliability (compared with traditional incandescent and fluorescent lamps, LEDs have a longer life);

 unlimited potential in increasing the luminous flux compared to point sources compatible with old fittings (there is no danger of overheating of the elements, the luminous flux is proportional to the length of the tape);

 the ability to implement original design solutions due to the flexibility and small thickness of the LED strip;

 the ability to select the light temperature and the desired color shade of the scene when using RGB - LED strips with controllers that allow you to independently control the brightness of each channel;

 obtaining a spectrum of light as close as possible to natural solar, which qualitatively affects the performance of people;

 lack of shadows and highlights;

 compliance with sanitary lighting standards.

Diffusers in the form of transparent profiles do not stand out due to their shape in the array of the ceiling, which allows to obtain a solid white array of the ceiling without gray spots of raster lamps, which are in the prototype, which is convenient for work and the human eye. You can also get any necessary level of coverage for specific workplaces or common areas. The system uses powerful LED strips for such purposes, the operation of which is impossible without heat dissipation radiators, however, in the proposed system, the profile itself serves as a steel radiator that removes heat to the ceiling, as a rule, unheated space.

 Having a special lock, the light diffusers are closed on the profile, covering themselves with pre-glued LED strips, providing soft scattering of light from the crystals of the LED strip, forming an even line that glows. It is possible to implement different lighting configurations. In the daytime, light diffusers are not visible on the ceiling area because they have the color of the profile system, and the ceiling as a result has a monolithic white surface without the usual gray bald spots for us, formed using standard lamps.

 Various modifications of the luminaire have high operational and technical indicators: high efficiency, efficient heat dissipation without installing additional heat dissipation radiators and a high color transfer index.

 The use of LEDs in fixtures allows you to achieve comfort in the perception of the human eye due to the lack of flicker (stroboscopic effect). The lamp itself is silent in operation and has a long service life.

In addition, the use of lighting elements pre-assembled under production conditions on the basis of rigid ceiling profiles of the structure itself during the installation of the ceiling structure allows us to exclude a separate operation for installing lighting equipment from the process, solving the lighting problem immediately at the stage of installation of the future profile system (frame) ceiling and significantly reducing the time of commissioning of the facility and reducing the estimated cost of installation work. Brief Description of Drawings and Drawings

 The invention is explained by the following figures:

 figure 1 - frame of the ceiling;

 figure 2 is a General view of the ceiling lighting system;

 in Fig.Z - T-shaped profile with LED strip;

 figure 4 - T-shaped profile with LED strip and light diffuser; 5 is a light diffuser, an embodiment;

 6 is a light diffuser, an embodiment;

 The ceiling lighting system contains a frame of rigid profiles 1, for example, T-shaped, made of metal with a thermal conductivity of 47–58 W / m * K, decorative panels 2 placed with the formation of a mesh structure.

 Rigid profiles 1 are interconnected in the frame by means of expanding springs, which consist of a tongue and a notch stamped in profiles 1.

 In the spaces between the decorative panels 2 there are placed lamps 3, which are made of LED strips 4, mounted on the protruding elements 5 of the rigid profiles 1, and which additionally contain light diffusers 6 in the form of transparent profiles of plastic materials. The LED strips 4 are placed LEDs equidistant from each other.

 LED strip 4 is mounted on the protruding elements 5 of the rigid profiles 1 using double-sided tape or self-tapping screws.

 Light diffusers can be hemispherical, triangular or rectangular in shape and made of polycarbonate. The diffusers 6 on the profiles 1 are fixed with longitudinal locks 7 in the form of two protrusions on the inner surface of the light diffuser 6, placed at its end. The protruding elements 5 of the rigid profiles have an additional polymer coating.

 Execution option

 The ceiling lighting system is assembled as follows. First, the ceiling support system is mounted from profiles 1 (600, 1200, 3600 mm long) by snapping one part into another. After that, LED strips 4 are glued onto the profiles and the strips are closed with light diffusers 6.

Due to the fact that during the installation of the ceiling structure are used pre-assembled in the production environment lighting elements based on rigid ceiling profiles, this design of the ceiling lighting system makes it possible to exclude from the process a separate operation for installing lighting equipment, solving the lighting immediately at the stage of installation of the profile system of the future ceiling and, at the same time, reducing time the commissioning of the facility and the estimated cost of installation work.
