Description

Technical field

The claimed utility model relates to the field of construction, namely to luminous building elements, and can be used for highlighting and / or decorative design of bike paths, pedestrian crossings, sidewalks, curbs, runways, illumination of park areas, directions for vehicles, and also for landscape lighting, architectural design, finishing of internal and external surfaces of buildings and structures, for installation in pools, fountains, etc.

State of the art

A luminous construction detail is known from the prior art (see patent RU 129517 U1 dated 06/27/2013), including an outer layer of a transparent polymer, a second layer made of the same polymer as the outer layer, and containing glass chips (glass cullet) with a linear the size of the pieces not exceeding 20 mm, a plastic conductive tape located along the perimeter of the tile inside the layer, an LED (s) placed on the tape, and a wire - a current lead. The part may contain a silicone liner, but may be produced without a liner. The plastic conductive tape can be additionally provided with a non-conductive frame. As a transparent polymer, the luminous building part contains epoxy or polyester resins. If necessary, a dye may be added to the resin. As a glass crumb, the item includes a cullet of transparent glass, colorless or colored, with a thickness of fragments not more than 5 mm, a width not more than 30 mm and a length not exceeding 10-30 mm. The conductor is brought out in the middle along one of the edges of the product.

The disadvantage of this solution is the uneven glow and color distortion. In addition, the disadvantages of this technical solution include the fragility of the product due to the multilayer technology and the relatively low service life due to the use of a frame, the use of which does not allow proper heat dissipation from the LED strip.

A luminous building element is known (see patent RU 205052 U1 dated 06/24/2021), containing a frame, on the inside of which an LED strip is placed around the perimeter and a composite layer placed inside the frame, containing a polymer base and a glass filler in the form of microspheres. The specified layer of the composite together with the frame and tape forms a monolithic product. The frame is made of plastic or metal (aluminum) profile. The specified profile has an L-shaped form, forming a horizontal shelf and a vertical wall for placing an LED strip on it. The frame may be of any suitable closed shape, such as square, rectangular, polygonal, circular, square or curved. The tape can use white or colored LEDs, or a combination of both. Two sealed connectors can be attached to the tape to connect the power supply, controller and other components. The composite layer includes a base (matrix) made of a polymeric material, in particular a cured epoxy resin, and a filler in the form of glass microspheres. The filler content in the layer is preferably 70-80 wt.%, the size of the microspheres is not more than 1.2 mm. The composite can be made completely transparent or painted in the desired color.

The disadvantage of this solution is the insufficient heat dissipation of the LED strip and, as a result, its short service life, since the product uses a plastic frame. Also, the use of an L-shaped frame leads to partial light loss of the product due to the lack of a base. In addition, glass microspheres have a slight greenish tint. At this percentage, as stated in the patent, the color becomes more saturated, which leads to color distortion of the light source.

The closest in technical essence to the claimed device is a building element (see patent RU 145358 U1 dated September 20, 2014), having a body made of a mixture of polymer and crushed glass. The polymer used is a transparent thermosetting resin with appropriate hardness, electrical insulation class and dielectric strength. Crushed glass is mainly glass chips with a particle size of 3 to 7 mm. Preferably, the polymer makes up 20 to 30% of the volume of the body, and the crushed glass forms the remaining 70-80% of the volume of the body. The body has the shape of a parallelepiped. The building element also contains a stiffening element, which is placed in the body. The specified stiffening element is made of a galvanized plate, which is bent up along the edges to form a bent area of the plate. The thickness of the plate is preferably 0.5 mm. The building element also contains a light emitting part, which allows light to be emitted from within the body. The light emitting part consists of a conductive strip and LEDs evenly placed on the strip. The strip, together with the LEDs placed on it, is located on the bent area of the plate. The LEDs are powered from an external power source through a cable that goes inside the body through a hole in the plate. The plate also has a clamp that secures the cable in position. In the embodiment shown, the clip is a clip that is cut into the material of the plate and that has an end connected to the plate.

The disadvantage of this solution is the fragility of the product and the uneven glow of the composite layer due to the use of only crushed glass in its composition. In addition, the described technical solution has insufficient thermal conductivity of the plate (due to the small thickness of 0.5 mm), which leads to a significant reduction in the service life of the LED strip, and insufficient cable tightness.

Utility Model Disclosure

The objective of the proposed utility model is to create a luminous construction detail with improved optical and performance characteristics.

The technical result is to improve the optical properties of the luminous element, which consists in increasing the uniformity of the glow, light transmission, reducing color distortion and the absence of shadows.

To achieve the set task and the technical result, it is proposed to create a luminous building part containing a box (1) made of a plate with edges bent at 90 degrees and a hole (2) for supplying power to the LED strip, at least one LED strip (3), placed on the inner side along the perimeter of the box on the bent sections of the plate and having a cross direction of LED luminescence, and a composite layer (4) containing a polymer base and a glass filler, and the specified composite layer together with the box forms a monolithic product. In this case, the box is made of metal with a thickness of 0.8-1.0 mm. The polymer base is 30-40% of the volume of the composite layer, and the glass filler is 60-70% of the volume of the composite layer. Epoxy or polyester resins are used as a polymer base. As a glass filler in the composite layer, crushed glass with a linear size of pieces not exceeding 20 mm and glass microspheres with a size of not more than 1.2 mm are used. The volume of glass microspheres is no more than 20% of the volume of the composite layer. Erklez can also be used in the composite layer instead of crushed glass. At least one hermetic connector (5) is connected to the LED strip to connect the power supply, controller and other components.

For the manufacture of the box, galvanized metal can be used.

The composite mixture can be made completely transparent or painted in the desired color.

Instead of an LED strip, it is possible to use LED strips with lenses (modules) to improve optical performance. The LED strip can be laid in 1, 2, 3 rows, or it can be wide, for example, more than 10 mm.

The product can have any shape: square, rectangular, triangular, polygonal, round or curvilinear.

The advantages of the proposed design include:

Improved optical properties of the finished product, namely the absence of a shadow, the absence of visibility of the diodes and the uniformity of the glow, the high light transmission of the composite layer, which eliminates the possibility of color distortion during the glow.

The use of glass microspheres in the composition of the composite as a glass filler, in addition to crushed glass, which makes it possible to reduce color distortion and increase light transmission and uniformity of luminescence due to the uniform distribution of glass particles in the composite layer.

The box is made of a metal plate with a thickness of 0.8 mm - 1.0 mm, which improves heat dissipation and increases the life of the LED strip, thereby increasing the life of the product as a whole.

The use of epoxy or polyester resin as a polymer base, which are more resistant to various loads, climatic changes and chemical influences due to high water resistance, heat resistance and frost resistance.

The use of a sealed connector with moisture protection and resistance to environmental influences.

Implementation of the utility model

In this section of the description, the most preferred embodiment of the utility model will be given, which, however, does not limit other possible embodiments explicitly following from the application materials and understandable to a specialist.

A luminous construction detail is made as follows. They take a sheet of metal (metal plate), cut it with a laser beam into various closed shapes: triangle, circle, rectangle, polygon, square, etc. A cutout is made in the corners in order to bend the edges 90 degrees and get a metal box. Next, the edges are bent to a height of 12-20 mm, and on the base of the box, a hole is made in the middle along one of the edges to output a sealed connector or wire. Then they take the LED strip and, having previously soldered it to the connector, glue it on the inside along the perimeter of the box onto the curved edges. The connector is brought out through a special hole in the box. After that, the mixture for the composite layer is prepared. To do this, take a resin, for example, epoxy, mix it with crushed glass with a fraction of up to 20 mm, for example, from 3-6 mm, then add glass microspheres with a fraction of 0.6-1.2 mm and mix again. The composite layer mix is poured into a plastic or silicone mold to make paving slabs, for example. The form is filled by 80-90% with the mixture or by 40-50% depending on the purpose of the product, then the box with the LED strip is immersed in the finished mixture, and the rest of the space is topped up with the remaining composition of the mixture. The hardening time of the finished product is approximately 72 hours at a temperature of 20-25 degrees. Next, the product is removed from the mold, and it is ready for use.

The specified product can be used as road surface elements, mounted on walls, ceilings, installed on sidewalks, roadways.

The use of a monolithic structure makes the claimed building part more resistant to various loads, and the use of glass microspheres in the composite layer, which act as a reinforcing effect, makes the product more durable.

The use of a plate as a stiffening element and as a basis for placing LEDs makes it possible to significantly simplify and reduce the cost of manufacturing a building element. In addition, the plate forms a reflective surface that enhances the reflective properties of the finished product.

The use of crushed glass in the composition of the composite layer in combination with glass microspheres makes it possible to achieve the absence of color distortion and the uniformity of the glow of the finished product.
