Description

The utility model relates to the field of lighting technology, namely to LED lamps, and can be used, for example, to illuminate building facades.

An integrated tubular lamp is known, consisting of a metal profile with plugs, on which an LED strip is installed, covered with a translucent cap (according to the patent CN104989979, F21S 2/00, F21V 17/10, F21V 17/16, F21V 29/70, F21V 29/503, published on October 21, 2015).

The disadvantage of this solution is the lack of adjustment for the angle of the lamp, as well as non-directional propagation of light.

A lamp is known, which is additionally equipped with a frame frame, and the base-radiator is made in the form of a plate - a base made of sheet metal, on the outer surface of which vertically oriented lamellas are installed parallel to each other, made in the form of thin-walled plates bent at an angle. In this case, the folded part serves for fastening to the base, and the end part is provided with convection holes. The power supply is mounted on base welded bushings providing an air gap between the base and the power supply. At the same time, the protective glass and the base are connected by means of a frame frame and fasteners, a bracket is fixed on the end parts of the frame frame (according to the patent RU158660, F21S 4/00, F21V 29/00, F21S 13/00, F21Y 101/00, F21W 131/00 , published 01/20/2016).

The disadvantage of this solution is the limited length of the lamp and the lack of unification of its nodes depending on the length.

Luminaires are known according to patents RU137707 (F21S 13/00, publ. 02/27/2014) and RU139332 (F21S 4/00, publ. 04/10/2014), which have a similar design and contain a radiator housing with a light source attached to it, connected via wires for supplying power and control to an external supply circuit, and attachment points for the lamp to the bearing support. The radiator housing is made in the form of a section of an angled metal profile having a constant cross section along its length and containing two shelves located at right angles, on the inner side of one of which an LED light source is fixed.

The disadvantage of the known solutions is that the attachment points are located at the edges of the profile, which limits the maximum allowable length of the lamp due to the inability to ensure the rigidity of the attachment.

Known profile for the body of the lamp, made in the form of a single piece and containing the base and perpendicular to it the ribs of a trapezoidal section. The base has a thickness of 4 mm and a width of 99.1 mm, the number of ribs is seven and they are placed on the base at the same distance from each other. The height of each rib is 48 mm, while on the side opposite to the ribs along the edges of the base there are walls 17.02 mm high, while all the above dimensions are made with a technological tolerance of ±0.05 mm (according to patent RU202817, F21V 29/76, publ. 09.03 .2021).

The disadvantage of this solution is that the lamp can only be fixed to the ceiling. There is no way to adjust the angle of the lamp. It is necessary to make mounting holes in the ribs to install brackets for hanging the lamp.

The closest technical solution is an LED lamp, which contains a radiator housing with a light source connected to an external power circuit, and a lamp attachment to a bearing support. The radiator housing is made in the form of a segment of a semicircular metal profile with a constant cross section along the length. The body-radiator contains a base having a flat surface on one side for placing a light source. On the opposite side of the base, a protrusion semicircular in the cross section of the profile is made, forming with the base along the entire length of the radiator housing a through cavity, inside which a C-shaped protrusion is formed in the center of the base. On the outer surface of the semi-annular protrusion along the entire length of the radiator housing, there are longitudinal heat-removing fins made in the form of radial T-shaped protrusions forming T-shaped grooves between themselves, and the outer ends of the T-shaped protrusions are located along the cylindrical generatrix of the radiator housing. The design of the luminaire allows the use of a mount and a connector with T-shaped protrusions (according to patent RU134612, F21S 4/00, publ. 20.11.2013).

The disadvantage of this solution is that the lamp can only be fixed to the ceiling. There is no way to adjust the angle of the lamp.

The technical result, which the proposed utility model is aimed at, is to ensure the installation and fixation of the LED lamp in various positions with adjustment of the angle of inclination and direction of light.

The specified technical result is achieved by the fact that the LED lamp consists of a metal profile with a constant cross section, plugs installed at the ends of the profile, at least two swivel mounts and an LED strip fixed along the profile and connected by wires to the power supply, and differs in that that each swivel mount consists of a bracket, on which a movable element is pivotally mounted with the possibility of fixation in various positions, while a groove is made in the movable element for fixing the metal profile.

In addition, protrusions can be made on the walls of the groove of the movable element, and grooves corresponding to the protrusions can be made on the metal profile.

In addition, the metal profile may have a visor.

In addition, the luminaire can be mounted on an additional mounting bracket.

In addition, the metal profile can be made of aluminum.

The proposed utility model is illustrated by the following drawings, which show a particular case of its implementation:

Fig. 2 - metal profile, axonometry;

Fig. 3 - swivel mount, axonometry;

Fig. 4 - installation of the profile in the mount, side view;

Fig. 5 - LED lamp on an additional mounting bracket, perspective view;

Fig. 6 - installation of the lamp in various positions.

The LED lamp (Fig. 1) consists of a metal profile 1, plugs 2 installed at the ends of the profile 1, swivel mounts 3 and an LED strip 4 fixed along the profile 1 and connected via wires 5 to the power supply 6.

Metal profile 1 (Fig. 2) has a constant cross section. Profile 1 has groove 7 for LED strip 4, grooves 8 and visor 9.

Swivel mount 3 (Fig. 3) consists of a bracket 10, on which a movable element 11 is pivotally mounted, which can be fixed on the bar 12 in various angular positions using a rivet (screw) 13. A groove 14 is made in the movable element 11, on the walls 15 which protrusions 16 are made.

The metal profile 1 is inserted into the groove 14 of the swivel mount 3 (Fig. 4) in such a way that the protrusions 16 enter the grooves 8. The LED strip 4 is installed in the groove 7.

The luminaire may have an additional mounting bracket 17 (Fig. 5), to which a swivel mount 3 is attached with the help of fasteners 18.

Application.

The lamp can be used, for example, for directional illumination of building facades (Fig. 6). The luminaire is installed under the roof visor 18. Using the swivel mount 3, you can choose and fix the direction of illumination.

The described design of the LED lamp allows installation on vertical, horizontal and inclined surfaces. 3 swivel mounts allow you to adjust the direction of the light. The use of a metal profile 1 makes it possible to accurately select the length of the luminaire. To do this, the profile is cut to the required length. The required number of swivel fasteners is selected for the desired length of the profile, which are distributed along its length with the step necessary for the rigidity of the structure. The use of LED strip also ensures the exact selection of its length for the dimensions of the profile.

Grooves on the profile and protrusions on the walls of the groove allow you to accurately position and fix the profile in the fixture.

The visor on the profile provides a directed distribution of light, and also closes the light source from the observer's eyes. Because of this, the light source on the facade is completely invisible. Only light remains visible.

An additional mounting bracket 17 expands the possibilities for installing and adjusting the lighting direction of the luminaire, for example, allowing it to be installed at a greater distance from the illuminated surface.

The execution of the metal profile 1 of aluminum ensures the production of the profile by extrusion. Thanks to this, the profile, and, consequently, the lamp can have a length of up to 6 meters.

Thus, the solutions presented in the utility model provide for the installation and fixation of the LED lamp in various positions with adjustment of the angle of inclination and direction of light, and thereby ensure the achievement of the technical result.
