When LEDs replaced traditional light sources in the field of home lighting and decorative lighting, lighting devices (luminaires) appeared that were based on different principles compared to traditional ones. In particular, many luminaires appeared with the principle of edge lighting, where the light guiding plates (LGP) were used to distribute the light from the LED light source located on the edges of the LGP, as opposed to the frontal luminosity , which is typical of all traditional light sources. Advantages of edge lighting lights compared to lights with front lighting:

• Lack of obviously luminous surfaces, such as lampshades from e.g. B. glass bulb of a lamp or LED matrices;
• the possibility of creating sufficiently large, independently luminous surfaces with a relatively low specific brightness of light emission;
• the ability to create a variety of designs not accessible to traditional light sources, including LED retrofit lamps;
• low glare and discomfort rates; low glare; high level of comfort of the created light environment.
• There are various technical solutions in this area.

The international patent application WO 2019 / 125218 A1 discloses an LED ceiling lamp consisting of a frame with LEDs mounted thereon, a ceiling made of translucent and reflective layers inserted into the frame and a power supply with a control device connected to the LEDs, characterized in that there is a hole in the center of the ceiling , into which the central support sleeve is inserted, to which the base and the frame are attached, the ceiling further comprising a light diffusing layer positioned under the translucent layer. The frame is manufactured such that a convection channel is formed between the base and the reflective material. The ceiling is attached to the frame in such a way that the LEDs on the edge of the translucent layer light up.

The Chinese utility model CN 204201542 U teaches an LED lamp with a light guide plate, whereby the LEDs are arranged in a center of the light guide plate and emit outwards in 360 degrees.

Another generic LED lamp is described in US patent application No. US 2009/086 480 A1 described, whereby here light is emitted radially outwards by centrally arranged LEDs and is reflected by a lampshade in a vertical direction.

When creating lighting devices based on edge lighting, three main approaches have been used in the prior art to date:

1. The use of hard LED strips (modules).

An example of such an approach is the Armstrong type of lighting (light panels).

Disadvantages: relatively high cost of the module due to the large size of the printed circuit board and a large number of LEDs (and therefore solder joints); the complexity of installing the module in the lamp (the need for soldering, mounting, etc.); the need to use large heat dissipation elements, the function of which is typically performed by a lamp frame made of a special aluminum profile with a total length of 2.4 m; a large number of additional constructive elements in the form of the upper metal protective plate, clamping gaskets, connecting corners, etc.; the complexity of assembling the entire structure due to the large number of brackets; the inability to create round shapes.

2. The use of flexible LED strips.

Disadvantages: relatively high cost per unit of luminous flux due to the large size of the printed circuit board and a large number of LEDs (and therefore soldering points); the complexity of installing the module in the lamp (the need for soldering, mounting, etc.); the complexity of assembling heat dissipation. This usually requires a special aluminum profile that allows for bends; a large number of additional structural elements in the form of the upper metal protective plate, clamping gaskets, connecting strips, etc.; the complexity of assembling the entire structure due to the large number of brackets; the impossibility of creating arbitrary forms; Lack of unification. Each lamp requires elements with special ones developed dimensions and electrical properties, which significantly complicates the development of such lamps and increases their costs.

3. The use of LED boards (modules) of a special configuration.

Disadvantages: relatively high cost per unit of luminous flux due to the large size of the printed circuit board and a large number of LEDs (and therefore soldering points); the complexity of installing the module in the lamp (the need for soldering, mounting, etc.); the complexity of assembling heat dissipation. This model usually requires specially designed structural elements; the complexity of assembling the entire structure due to the large number of brackets; the impossibility of creating arbitrary forms; Lack of unification. Each lamp requires elements with specially designed dimensions and electrical characteristics, which significantly complicates the development of such lamps and increases their costs.

The technical problem in this area is therefore the lack of a simple, unified LED light source based on the edge lighting principle. The proposed technical solution will solve this technical problem and expand the product range.

The ceiling is an optical light-conducting and radiating component. The ceiling can be an LGP ceiling.

A cooler is installed on the top of the base. In the center of the ceiling, the hole is created for placing a board with LEDs, which is attached to the surface of the base in such a way that the LEDs transmit light to the edge of the ceiling. The power supply and control device is positioned in the upper part of the base in the cavity provided for it.

The technical result consists in improving the technical properties of the LED module, namely in removing glare and high glare effects while increasing energy efficiency and expanding the application possibilities.

In the LED module, comprising a base 5 with a support surface on which LEDs 9 are mounted on a solid or segmented flexible circuit board 8, power supply and control device 4 positioned in the cavity of the base 5, the cover 13 which is attached the base 5 is fixed, and a ceiling 11. The base 5 is made such that there is space between the base 5 and the cover 13 to place a ceiling 11 therein, which is fixed using flanges 10 and 12, which are positioned along the perimeter of the base 5 and the cover 13. On the top of the base 5 there are radiator fins 2. In the middle of the ceiling 11, the hole is created for placing a board 8 with LEDs 9 in it, which are mounted on the support surface of the base 5 so that the LEDs transmit light to the edge of the ceiling . The power supply and control device is positioned in the upper part of the base 5 in the cavity provided for this purpose. The elements used in the power supply and control device are positioned in Zone 7.

The cooler 2 is made in the form of radially arranged, curved fins to ensure effective heat dissipation.

Around the LEDs 9 in the in 4 In the version of the module shown, there is a transparent protective element 14, which is attached with a cover - to protect the board with LEDs from damage. The LEDs 9 are mounted on a printed circuit board 8, which is solid or consists of several segments and is positioned around the support surface of the base. The LEDs 9 can glow warm and/or cold white, or glow in different colors and can be switched on all at once or in any combination using a control device.

The cover 13 has a fastening hole 6 in the middle part in order to create multi-layered lights with ceilings arranged one below the other on the same vertical axis.

The module is attached to the supporting structure using the threaded hole 1 present in the top part of the base.

The LED module can have an original power connection 3.

Along the perimeter of the flange 10 of the base 5 there are (in some design options) slots for placing and fixing the hollow plafond 11.

The ceiling 11 can be flat, curved, concave or convex and can have a round or any other shape according to the design of the lamp.

To give the module the desired color or design, a decorative cap 17 is attached to the bottom of the flange 12 (in the version of the LED module with additional structural elements). The flange 12 of the cover has special protrusions and recesses for attaching a decorative cap to it.

The design of the LED module is made of aluminum (brass, or the base is made of metal, and the other elements are made of plastic).

The LED module is attached to the support structure of the lamp using an existing hole on the base 1 with an internal thread.

The module is connected to the lamp's power supply system via the available connection 3 in the power supply and control device 4.

A ceiling 11 is installed on the LED module, which is secured by flanges 10 and 12 attached to the base 5 and the cover 13.

The ceiling 11 of any shape is made in the form of an LGP plate or in the form of a thin-walled inflated ceiling made of light-diffusing plastic. The LGP panel can be designed both with and without a reflective layer. In the latter case, the light is distributed on both sides of the plate. Glass can also be used for edge lighting with frosted surfaces.

Plafonds can be both flat (two-dimensional) and have bends along the third coordinate (three-dimensional).

A threaded hole 6 in the center of the cover 13 is used to build multi-layered lamps with ceilings arranged one below the other on the same vertical axis. This hole is not used in the construction of single layer lights.

The LED light source is positioned at the base and allows the light to be sent into the edge surface of the ceiling through its central hole.

In one implementation, the dimensions of the fully assembled LED module (without ceiling) are 32 mm in height and 66 mm in diameter. The thickness of the glass in the LGP panel is 4 mm. The diameter of the hole in the plate for installation in the module is 46 mm.

When installing the LED module into the lamp, the base of the module is attached to the supporting structure, then the ceiling is put on and secured through the cover. After assembly it is possible to adjust the ceiling positioning.

In one implementation: the LED module is powered with a constant voltage of 36 V, power is provided via a compact power supply with a power of 75 ... 100 W, positioned inside the lamp structure.

When the base of the module is attached to the supporting structure, it is connected to the lamp's power supply system, like screwing in a regular light bulb.

In one of the implementations of the LED module: it contains two groups of LEDs - white LEDs for warm and cold light with a color temperature of 3000 K and 6500 K, respectively; The module also has an integrated circuit board with a microcontroller that can be used to control both the color temperature of the lamp lighting and the brightness in the range from 0 to 100%.
