The closest analogue of the same purpose as the claimed invention is a lighting system containing:

- a housing on which the light-emitting element is installed and to which the rotary barrel is ring-shaped;

- a rotating frame including a peripheral edge section at one peripheral end having a substantially cylindrical shape inserted into the mounting hole of the ceiling plate, wherein the rotating drum is rotatably mounted in the rotating frame;

- holding sections attached to the rotating frame, in a state in which the rotating drum is mounted on the rotating frame, the holding sections holding the installation of the rotating barrel on the rotating frame;

- resilient sections attached to the pivot frame, the resilient sections enclosing the pivot frame, retaining sections and ceiling plate using a resilient force in combination with the circumferential edge section (EP Publication 2846076, IPC F21S 8/02, F21V 14/02, F21V 21/ 04, 2014, 2015, https://patentscope.wipo.int/search/ru/detail.jsf?docId=EP131294940&_cid=P11-LLP5NY-82973-1).

Known devices have the following general disadvantages:

- inability to fine-tune the angle of inclination after installation;

- narrow range of tilt angle adjustment without affecting the size of the luminous flux;

- open installation.

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 increase the technical characteristics of the device, in particular, to prevent unwinding during use with simultaneous smooth operation and the ability to tilt and rotate in the ceiling area, which significantly disguises the device in the interior with minimal loss of luminous flux.

The problem is solved, and the technical result is achieved due to the fact that the tilt-and-turn housing of the lamp, which is a ring, contains a rotating unit offset from the center, which is a screw and a hex nut, which tighten the hinge of the tilt-and-turn housing located in the upper part on the edge , which corresponds by a hole with the same edge loop of the reflector hood, as well as a fluoroplastic bushing located between these loops, and a countersunk screw is installed in the hole of the hinge of the reflector hood body in such a way that it presses the rubber ring in the screw stop position, and the hex nut installed in the hexagonal groove of the tilt-and-turn housing, in the body of the reflector hood metal screws with a cylindrical head are screwed in to attract neodymium magnets glued using adhesive-sealant on the body of the protective casing with graduation.

Displacement of the rotation unit relative to the center allows you to increase the range of the device’s tilt angle to 0-30 degrees while maintaining the light flux without cutting it off. A fluoroplastic bushing acting as a compensator, which is clamped between the hinges of the tilt-and-turn housing and the reflector hood, ensures smooth rotation of the device during use, preventing the screw and hex nut from unscrewing after several dozen turns. The installation of a hex nut in the corresponding groove and the location of the screw head with the pressure of the rubber ring also prevent unwinding. A protective casing with graduations serves to accurately set the angle of inclination of the device, and setting the angle of inclination can be done already with the lamp mounted on the ceiling without the need to remove it. It also allows you to hide the ceiling space, which will be open when tilted to the maximum angle.

To unify the product, the tilt-and-turn housing contains protrusions for engagement with two-level radiator mounts with a light source and optics.

Figure 2 shows the point of attachment of the protective casing 9 to the body of the reflector hood 8 in the form of a reflector hood screwed into the body 8 a metal screw with a cylindrical head 10, which attracts a neodymium magnet 11, fixed with adhesive-sealant on the body of the protective casing 9. The specified attachment points are located and attract the body of the reflector hood 8 and the body of the protective casing 9 in five places.

In fig. Figure 3 shows a general view of the claimed invention assembled with a radiator with a light source 12 and a mounting frame 13.

Carrying out the invention

Before using the tilt-and-turn housing in a recessed luminaire (Fig. 3), the tilt-and-turn housing 7 and the reflector hood 8 are fastened together using a screw 3 passing through the hinge of the tilt-and-turn housing 2 and the loop of the body of the reflector hood 6, between with which the fluoroplastic sleeve 4 is located. On one side, the screw 3 is fixed with a hex nut 1, and the head presses the rubber ring 5. Next, using neodymium magnets 11, a protective casing 9 is installed on the body of the reflector hood 8.

Various accessories can be located in the tilt-and-turn housing 7: anti-glare grille, protective glass for IP protection , DTF film (oval light effect) combined with transparent IP glass, etc.

After installing the accessory, the tilt-and-turn housing 7 is inserted with the corresponding protrusions into the two-level bayonets of the radiator with the light source 12 and rotated clockwise.

A safety cable is fixed in the hole of the tilt-and-turn housing 7. The driver's power is connected, and it is driven into the ceiling space. The driver connector is connected to the lamp plug. The radiator with the light source 12, in engagement with the tilt-and-turn housing 7, is inserted into the mounting frame 13 and rotated until it stops.

After installing the lamp in the mounting frame 13 on the ceiling panel, the angle of inclination is adjusted. To do this, it is necessary to apply force to the area of the reflector hood 8, rotate the tilt-rotary housing 7 clockwise or counterclockwise and adjust the angle of inclination according to the graduation marked on the protective casing 9.
