The horizontal elements of the flanges are used to fix the base to the plane of the ceiling.

[0004] Known

[0005] (https: / / styllight.ru / upload / iblock / e96 / ut8vg3h4pl6chmbgkh1sn2r8khurjleg.pdf) HIDDEN LED luminaire, SQUARE series (manufacturer OOO "STILNY LIGHT"), recessed into suspended ceilings, consisting of a base (mounting box) and two movable elements in the form of L-shaped flanges installed on opposite sides of the base, each of which is designed to move along the base axis due to the vertical grooves on the sides of the base, which serve as guides for the fixing screws (fasteners) of the flanges. The horizontal elements of the flanges are attached to the plane of the ceiling.

[0006] The main disadvantage of the two above-mentioned devices is the difficulty (skew, insufficient accuracy) of setting and adjusting the lower edge (front part of the base) of the base to the ceiling level using separately movable flanges.

[0007] A LED luminaire built into a suspended ceiling, the Zero Mounting Kit, DOT220 V series (manufacturer Technolight), is known (https: / / technolight.ru / products / interernyi-svet / dot-220v / montaznyi-komplekt-zero / 40001-89). It consists of a base and a movable element, designed to install a lighting element, made with the possibility of coaxial installation and adjustment of their relative position with subsequent fixation of the movable element in the base, characterized in that the base is made with two opposite flange projections for fastening to a suspended ceiling. Fixation of the position of the movable element in the base of the luminaire, pre-fixed in the suspended ceiling, is carried out due to the horizontal displacement of the corresponding clamp towards the movable element.

[0008] A known (https: / / kraab-systems.com / pinch-pincher-gipps / ) is a PINCH & PINCHER GIPPS LED luminaire (manufacturer Kraab-systems) built into a suspended ceiling, consisting of a base and a movable element designed for installing a lighting element, made with the possibility of coaxial installation and adjustment of their relative position, followed by fixation of the movable element by wedging in the base.

[0009] The main disadvantage of these two devices is the lack of protection against the movable element falling out and the lack of additional protective elements to protect the light module from falling out.

[0010] The closest to the claimed utility model is the known one (RU 217243 U1, published 03 / 23 / 2023), from which a built-in ceiling light is known, which contains a base and a movable element intended for installing a lighting element, made with the possibility of coaxial installation and adjustment of their relative position with subsequent fixation of the movable element in the base.The base is provided with two opposing flange projections for fastening to a suspended ceiling; the position of the movable element in the base of the luminaire, previously secured in the suspended ceiling, is fixed by horizontally shifting the corresponding clamp towards the movable element, where the clamps are installed in grooves made on opposite side surfaces of the base, each having an inclined surface, when pressed by the corresponding fastening screw while screwing the latter through a threaded hole in the base of the luminaire, along its longitudinal axis, the movable element is clamped in the base.

[0011] The technical challenge is to achieve a gapless, frameless connection of the luminaire to the sheet material of the ceiling, since the luminaire is integrated into the ceiling in one plane, without protruding frames or elements, which is achieved by a very tight connection and fixation of the parts.

[0012] Furthermore, the implementation of such a device increases the safety of the lighting fixture and reduces the labor intensity of installing it into the ceiling. Adjustable installation height simplifies finishing the ceiling.

[0013] The technical result is an increase in the reliability and accuracy of the connection and fixation of the parts of the ceiling recessed luminaire, ensuring its tight and stable fastening in the mounting hole of the suspended ceiling.

[0014] The specified technical result is achieved by a ceiling recessed light fitting comprising a base 1 for mounting to the ceiling and a movable element 2 made with the possibility of coaxial installation and adjustment of their mutual position with subsequent fixation of the movable element 2 in the base 1, the base 1 is made with two rectangular flanges 11 and roundings in the corners for mounting to a suspended ceiling, a mounting screw 3 is provided on the end part of the base for fixing the movable element in the base, a dimension ruler 10 is provided on the end part of the movable element 2 for more precise installation, a flange 7 is provided on the upper part of the movable element to prevent complete unscrewing of the movable element 2, a threaded hole with a screw 4 is provided in the flange part for fastening a safety cable 5.Movable element 2 has projections 9 that secure light module 6 via L-shaped grooves 13 on light module 6 and prevent rotation. The luminaire on the top of movable element 2 has a flange 5 that prevents the movable part from being completely unscrewed after the base is installed on the suspended ceiling. The luminaire has a rectangular flange 11 with rounded corners.

[0015] To clarify the essence of the claimed utility model, the following graphic materials are provided:

[0038] The movable element 2 is installed in the base 1 with the possibility of longitudinal movement along the axis (coaxial displacement) of the base fixed in the ceiling, due to the thread 8 of the movable element 2 and the thread 12 of the base 1. Additional fixation is carried out by the set screw 3 for fixing the movable part. The longitudinal displacement of the movable element 2 inside the base 1 allows for easy and precise setting of the desired height of the front part (lower edge or decorative flange) of the movable element 2 to the required (within the established range of movement) thickness of the suspended ceiling layer, taking into account the putty layer during rough finishing work. Adjustment of the position of the front part of the movable element 2 to the ceiling level is carried out in the range from 0 to 25 mm, where 0 mm is the ceiling level, and is necessary for any luminaire installation scheme, since the ceiling layer may vary in thickness.

[0039] The rectangular flange 11 and rounded corners of the base 1 allow for installation, including from the upper (inner) side of a suspended ceiling, and also ensures a gapless, frameless connection between the luminaire and the ceiling sheet material: the luminaire is integrated into the ceiling in a single plane, without protruding frames or elements. The mounting holes on the base flanges are typically countersunk.

[0040] The flange is rectangular with rounded corners, increasing the contact area when installed on the back of a suspended ceiling. Mounting is accomplished using screws that are driven into the suspended ceiling and, when inserted into the holes in the flanges, pull the base toward the ceiling.

[0041] On the top of the movable element 2, there is a flange 7 that prevents the movable part from being completely unscrewed after the base is installed on the suspended ceiling. On the luminaire's flange 7, there is a screw 4 for attaching the safety cable 5 to the light module 6, which ensures the luminaire's safety during operation and maintenance.

[0042] Light module 6 is secured in movable element 2 by projections 9 facing (directed) toward the central axis. During installation, the projections on movable element 2 align with L-shaped grooves 13 on the light module, and module 6 is inserted until it stops. Module 6 then rotates around its axis, and the projections engage locking pockets 14. Once in place, the projections prevent the module from rotating around its axis.

[0043] The utility model features a device that, by its design, prevents the movable part from completely unscrewing when the base is secured to a suspended ceiling. This lack of protection in similar fixtures can lead to misalignment or damage during reinstallation (assembly / disassembly). Furthermore, additional protection is provided for the LED module against falling out, which could damage the power cables, objects, or people underneath the luminaire. This also improves the luminaire's operational safety and ensures safe maintenance.

[0044] This recessed ceiling light is designed for convenient and safe installation and easy maintenance. Assembly requires no complex tools to ensure a strong and secure fit. This reduces installation labor. This lighting fixture boasts an aesthetic appearance while fulfilling its primary function.
