A modular recessed ceiling lamp is known, characterized in that it contains a light source and a connected reflector for placing a light source underneath; pad for fixing the reflector; a radiator made of a curved shape and containing lamellas with an air gap between them; mounting frame and spring fixing unit for securing the mounting frame (utility model patent No. 189749 U1, IPC F21S 8/04, 2019, Bulletin No. 16, 2019, https://new.fips.ru/registers- doc-view/fips_servlet?DB=RUPM&DocNumber=189749&TypeFile=html).
The disadvantages of the known utility model are:

- increased complexity of installation and dismantling of the device due to the location of the mounting frame on the front plane of the ceiling sheet, since finishing work is required in the area where the lamp is installed, and when dismantling the lamp, damage to the finish is possible, which can crack and fall out from the visible parts of the front plane;

- one reflector height without the possibility of variability and fine-tuning of the re-reflection of the light flux;

- lack of protection from moisture and dust;

- the need to disassemble the device to repaint the product;

- fixation of optics (lenses) using a clamping ring, which requires the use of a special additional tool to replace it;

- fixation of the lamp on spring bearings, which greatly complicates its removal from the niche for maintenance and requires the use of special additional tools.

The closest analogue of the same purpose as the claimed invention is a recessed ceiling lamp, characterized in that it contains a light source; reflector to place a light source underneath; a lining for fixing the reflector, with a groove made on the outer surface of the lining; a radiator containing lamellas with an air gap between them; a mounting frame having a ball spring to fit into the groove of the lining, while the radiator is designed to be fixed on the lining (utility model patent No. 189779 U1, IPC F21S 8/04, 2019, Bulletin No. 16, 2019, https://new.fips.ru/registers-doc-view/fips_servlet?DB=RUPM&DocNumber=189779&TypeFile=html).

The disadvantages of the known utility model are:

Disclosure of the invention

The objective of the claimed invention is to eliminate these disadvantages of analogues and the prototype. The technical result of the proposed technical solution is to facilitate the installation, regulation and further maintenance of lighting fixtures built into ceiling structures with the ability to quickly replace the component elements of the device due to the unified fixation of the elements with each other.

The problem is solved, and the technical result is achieved due to the fact that the recessed lamp includes a mounting frame, a light module with a lens, a housing with an accessory, and the inner part of the mounting frame, made with spring ears or with the ability to screw in legs for attaching the frame to the ceiling, contains pairs of “labyrinth groove with a collar and a thrust bearing located underneath” located opposite each other for fixing the case, the light module is a needle-shaped radiator of a hemispherical shape, in the lower part of which two two-level bayonets are located opposite each other for insertion of the corresponding protrusions on the case, with In this case, the housing can have one of the following types of design: stationary design, tilt-rotary design with or without a rotating insert, magnetic design.

Regardless of the design of the mounting frame, the ears and tabs for fastening to the ceiling sheet are installed in the ceiling space without the need for finishing work after installation of the device. The pairs of “labyrinth groove with a shoulder and a thrust bearing located underneath” located in the inner part of the mounting frame opposite each other make it possible to securely and without additional effort fix the housing not only of a stationary design, but also of a tilt-rotate one with 360-degree rotation. In addition, the labyrinth groove absorbs significant loads in the direction of the vertical axis, and the protruding flange of the labyrinth groove limits the unwinding of the device when vibrations of the ceiling sheet occur. A two-level bayonet allows you to close the IP circuit with tension at the top point and firmly fix it. In this case, the upper groove allows you to install a translucent insert, and the lower groove allows you to install various accessories with a thickness of up to 3.5 mm. Due to two levels of fastening, the versatility of the product is ensured due to the possibility of integrating various additional elements. The hemispherical needle radiator provides high heat dissipation efficiency thanks to a design that provides the largest possible heat dissipation surface area, as well as maximum convection efficiency even when the element is deviated from a horizontal position.

The tilt-and-turn design of the body is implemented by installing a rotary hinge with a tilt limiter, while the rotation is fixed by means of a compensator - a fluoroplastic bushing, which is clamped by the rotary hinges and ensures smooth rotation without unwinding during several dozen turns. The magnetic design of the case is realized using neodymium magnets located in the grooves of the case with screw fixation, to which a steel plate is attracted. The housing in the tilt-rotary design may additionally contain a rotating insert of complex volumetric shape installed inside, the rotation axis of which is aligned with the rotation axis of the housing.

Making the lamp body from aluminum increases the strength of the device and, accordingly, extends its service life while reducing the likelihood of accidental damage.

To ensure a tighter fit of the elements to each other, an o-ring is installed in the upper part of the body, the other side of which is adjacent to the accessory.

Anti-glare grille, microprism or matte microprism can be used as accessories.

To be able to regulate the installation of the device, marks indicating the thickness of the plasterboard sheet in the range from 9 to 24 mm are applied at the places where the legs are attached to the mounting frame.

To accurately set the angle of inclination of the light module, a reflective casing with graduations is installed on the tilt-rotary housing using magnets.

To allow the installation of additional elements, for example, motion sensors, light sensors, various entrance/exit signs, CCTV cameras, the magnetic steel plate of the housing can be made with a hole in the center of any diameter.

Brief description of the drawings (if they are included in the application)

The claimed invention is illustrated by means of figures 1-3 using the following notation:

1 - mounting frame;

2 - ears;

3 - lens;

4 - light module;

5 - body;

6 - accessory;

7 - sealing ring;

8 - labyrinth groove with collar;

9 - thrust bearing;

10 - two-level mount;

11 - reflective casing with applied graduation;

13 - rotary insert;

14 - paws.

Figure 1 shows two versions of the mounting frame 1 of the inventive recessed luminaire: a - with spring ears 2, 6 - with the possibility of screwing the legs 14. The ears 2 and legs 14 are located on the outside of the annular mounting frame 1. On the inside of the mounting frame there are pairs of “labyrinth groove with a collar 8 and a thrust bearing 9 located underneath” located opposite each other for fixing the housing 5. Figure 2 shows three versions of the housing 5: a - tilt-rotary design, 6 - magnetic design, c - inclined - rotary version with rotary insert. On the housing 5 of the tilt-rotary design (Fig. 2, a), to accurately set the angle of inclination of the light module 4, a reflective casing with applied graduation 11 is installed using magnets. A steel plate 12 is installed on the housing 5 of the magnetic design (Fig. 2, b), which masks the transition from the ceiling surface with a decrease in the light window. With this design of the housing 5, it is possible not to install the light module 4, but to use a lamp to integrate motion sensors, fire safety or light indicators with making a hole in the steel plate 12 of the diameter required for the corresponding device. The rotary insert 13 (Fig. 2, c) allows you to direct the light flux after installing the lamp, while the lamp itself does not need to be rotated, but just change the angle of the rotary insert 13.

One of the embodiments of the proposed device with a mounting frame with the ability to screw the legs and with a stationary housing is shown in Fig.3. The recessed luminaire includes a mounting frame 1, a light module 4 with a lens 3, a housing 5 with an accessory 6. The light module 4 is a needle-shaped radiator of a hemispherical shape, in the lower part of which two two-level bayonets 10 are located opposite each other for insertion of the corresponding protrusions on the housing 5.

Unified clamps in the form of pairs of a “labyrinth groove with a shoulder 8 and a thrust bearing 9 located underneath” and a two-level bayonet on the light module 4 allow you to quickly change various elements of a recessed luminaire, for example, a stationary housing with a tilt-and-turn housing, without the need for complete dismantling and the use of special additional equipment.

Carrying out the invention

Before installing the recessed luminaire, it is necessary to prepare a niche for installing the mounting frame. For ceilings made of hard materials, a hole with a diameter of 100 mm is made. For suspended ceilings, a mortgage with a hole of similar size is prepared.

When installing the mounting frame 1 with spring ears (Fig. 1, a), the ears 1 are pressed out, alternately inserted into the ceiling, and then released, and the mounting frame 1 is independently fixed in the hole.

In the version of the mounting frame 1 without spring ears (Fig. 1, b), first the legs 14 are screwed from the outside to the mounting frame 1 with the required height set depending on the thickness of the plasterboard ceiling. Then the mounting frame 1 is inserted vertically through the hole and placed with its ribbed surface down on the hole. Next, the approximate location of the legs 2 is outlined for screwing them on with a self-tapping screw.

When assembling the recessed lamp (Fig. 2), the lens 3 is inserted into the light module 4 and turned clockwise until it stops. Next, the accessory 6 is placed on the rubber o-ring 7 of the housing 5, which, with the accessory 6 installed, is inserted into the two-level bayonets 10 of the light module 4 and rotated clockwise.

A safety rope is fixed in the hole in the housing 5. The driver's power is connected, and it is driven into the ceiling space. The driver connector is connected to the lamp plug. If necessary, the angle of inclination of the lamp can be adjusted. The light module 4 with housing 5 is then inserted into the mounting base until it stops, while the grooves of housing 5 and mounting frame 1 must coincide, and is rotated until it stops.
