Description

Description of the invention

The subject of the invention is LED lighting.

LED lighting is increasingly used as the main light source to illuminate the interior of houses, apartments, workplaces, commercial buildings and in outdoor applications such as street lighting, architectural lighting, etc., as well as for specialized applications, including in the automotive industry. The advantage of such solutions is low power consumption, the ability to choose a shade of white and durability of lighting. Moreover, such lighting does not generate high temperatures, so it does not carry a fire risk or cause black spots on the walls.

In LED lighting, it is also possible to use high-power LEDs, which enable lighting of larger objects, such as warehouses, production halls, parking lots, gardens, etc.

Beautiful, saturated colors, obtained in RGB LED, enable colorful, decorative lighting of restaurants, gardens, etc.

Flexible LED strips known in the art and available on the market (regardless of the size and application, emitting both monochromatic and RGB light) are mounted in metal, most often aluminum profiles. The commonly used method of assembly is that the LED strips are glued directly to the aluminum profiles. Unfortunately, this way of mounting the tape means that the tape loses from a few to a dozen or so percent of light power with each meter. These problems result from a voltage drop of a few Volts on the strip, e.g. in the case of an 8-meter section, the voltage drop on the LED strip is about 3 V. With a standard 230-volt power supply, such voltage drops would not be felt, but with LED lighting, where in depending on the tape, the voltage is 12 V or 6 V, a voltage drop of 25 to 50% affects the quality and strength of the light obtained.

Hence, in order to limit voltage drops, a power supply (converter) connected with cables in parallel to the power source is mounted, e.g. every 5 meters of LED strip. A diagram of such a standard connection is shown in Fig. 1. The longer the sections, the more cables with a larger cross-section are needed.

LED lighting mounted in such a way, despite the fact that it is low-voltage and does not consume much electricity, is expensive, both due to the materials used and the high cost of installation - "connecting" and soldering power cables every 5 meters takes quite a lot of time. Such assembly also affects the aesthetics of the solution.

In a situation where the tapes are mounted outside at different angles, the effect of joining tapes with cables weakens the visual value. In addition, when illuminating longer sections, the disadvantage of such a solution is the need to purchase additional power supplies, drivers, etc.

The aim of the solution according to the invention is to provide LED lighting that solves the problems of supplying linear lighting based on LED diodes and enables cheaper and faster assembly, elimination of voltage losses, as well as increasing the visual qualities of the installed lighting.

The LED lighting according to the invention, consisting of a profile and an LED strip, is characterized in that an insulating layer and conductive tracks are attached between the LED strip and the profile, while the insulating layer and conductive tracks are in the form of a conductive tape glued directly to the profile or embedded in it. profile.

Any insulating material can be used in the solution according to the invention. The dimensions of individual elements can also be arbitrary.

A tape consisting of an insulator and conductor strips can be glued directly to the profile, or conductor strips (e.g. copper) can be glued to an aluminum profile coated with insulation.

Also, the number of conductive tracks on the supply belt can be any and depends on the type of lighting used. In the case of white light, most often it will be two paths, while in the case of RGB (color change) light, 4 paths can be used.

Conductive tracks can be made of any conductor (conductive material), incl. copper, silver-plated copper, aluminum strips embedded in a silicone backing or flooded with silicone, etc.

Depending on the purpose, any additional cover / protective layer can also be applied to the LED strip.

The advantage of the solution according to the invention is that there is no need to use a power bus parallel to the strip (both inserted into the profile and not). Voltage drops in long sections are minimal, which significantly improves the lighting parameters of the LED strips.

In addition, scissors and a small soldering iron are enough to assemble such a solution. There is also no problem with joining the tapes at any angle, just cut the base or profiles with the conductive tape and solder the LED strip to the base. As the profiles are easy to install and the tapes are also easy to stick to the underlay, the installation time is also shorter. The power strip according to the invention also solves the aesthetic problem - especially at joints, the risk of damaging the LED strip is lower.

In the three-layer version (insulation - conductive paths - insulation), the lighting is suitable for outdoor applications.

The cost of the solution according to the invention is comparable to the cost of an ordinary cable.

With the simultaneous use of aluminum profiles, this gives a solution to all of the above-mentioned problems, because the power tape can be glued directly to the profile under the LED strip.

The subject of the invention is presented in the example of the embodiment in the drawing, in which Fig. 1 shows an example of the solution according to the invention using LED lighting emitting white light, Fig. 2 shows an example of the solution according to the invention using LED lighting emitting RGB light, Fig. 3 shows a cross section of the lighting , Fig. 4 is a top view of the illumination.

The solution according to the invention consists of a profile 1, to which a power strip 2 is glued consisting of an insulating layer 3 and conductive tracks 4. A LED strip 5 is glued to the power strip 2. The contact points 6 of the power strip 2 are connected to the transducer 7 (e.g. 12 V) connected to the voltage source 8. The LED strip 5 has contact points 9 that are soldered to the conductive tracks 4 on the power strip 2.

With such a solution, for example, the cross-section of a 2 x 1.8 mm ² power strip on a tape with a thickness of only 0.8 mm allows you to place a led strip up to 30 m from one power supply located at the beginning of the strip, without the need to "burn" it every 5 m.
