Description

The utility model relates to lighting engineering, namely, to LED lamps and can be used as a lighting device in various fields, rooms, including with high humidity and dust.

From the prior art, an aluminum profile of a light panel with an end radiation input is known (patent for utility model RU 153372, publ. 07.20.2015), in which a light-diffusing panel element and a radiation source are installed, consisting of boards with LEDs placed in the grooves of the profile, the radiation of which introduced through the end face of the panel element, reflected from its back surface and displayed through the front scattering part, equipped with four plastic corners connecting the rectangular profile elements in a closed Tour by fixing the connecting elements in the corners of the grooves of the profiles, and the corners are provided with additional tabs protruding into the circuit. The disadvantages of this technical solution is that the LED boards are installed on the end of the profile, thereby directing the light flux emitted by the LED to the end of the diffuser, which reduces the efficiency of use of the light flux. Also, this light panel is complicated by the process of applying light distribution marks to the surface of the diffuser. All of the above increases production costs in the production process and reduces the efficiency of the lighting device.

Known LED ceiling lamp (RU 115441, publ. 04/27/2012), comprising a prefabricated frame and mounted therein a heat-reflecting base-reflector with LED lighting modules and a light diffuser. The prefabricated frame consists of profiled sidewalls and corner lock connectors. Grooves are made in the sidewalls and in the corner lock connectors for mounting a heat-reflecting base-reflector and a light diffuser. The heat-reflecting base-reflector is made in the form of a thin-walled metal plate, on the inside of which LED modules are fixed. Each of the modules is a single-sided printed circuit board with a chain of LEDs placed on it. The light diffuser is made in the form of a sheet of translucent polymer.

The disadvantages of this technical solution are

low mechanical strength (rigidity) of the structure, detachable fastening of the corner and polymer profile does not have mechanical ties with the base, and therefore, to ensure this parameter, there is a need to use a heat-reflecting base-reflector with a thickness of 0.8-1.2 mm;

the presence of an external power supply, which makes it impossible to use this design in an overhead version (mounting on a flat surface).

Closest to the claimed technical solution is the LED ceiling lamp (RU 32160, publ. 09/10/2013), which is a prefabricated frame including a metal heat sink with LED strips mounted on it, an optical diffuser made opposite the base, side walls made in the form profile with internal grooves formed by longitudinal shelves for mounting the base and diffuser, corner elements that fix the side walls by means of connecting nodes, seal IR in the grooves and connecting nodes, the power supply mounted on the base and fed through an opening made with a seal at the base, the outer shelf of the internal groove for the diffuser is made in the form of a segment with the convex side outward, the corner elements and side walls are made of equal height, and the conjugation angle the angular element in height and in the plane of the diffuser is rounded, and the connecting nodes on the side walls are made in the form of shelves parallel to the side walls, the power supply is installed inside the luminaires ika and the voltage supplied to it through the sealed junction box located on the basis of the outside lamp and provided with a pressure seal. The disadvantages of this technical solution are:

low mechanical strength and stiffness of the product,

the need to manufacture a special profile with a given contour, which makes it impossible to use this solution in small-scale production.

The problem to which the claimed utility model is directed is to ensure a reliable and quick connection of the elements of the lamp. The lamp housing is made of parts and materials widely used in industry. Ensuring the unification of the used parts and elements allows you to form a variety of size and shape of the housing, and, accordingly, of the fixtures, and various designs of fixtures, such as overhead, built-in, pendant and others, are possible.

This problem is solved due to the fact that the claimed LED lamp is a prefabricated frame, including a base for mounting LED boards on it, an optical diffuser made opposite the base, side walls made in the form of a hollow profile and at least one internal groove formed by longitudinal shelves for installing the diffuser, corner elements. The base is attached to the profile along the perimeter using self-tapping screws, which ensures sufficient rigidity of the lamp housing even when using a base made of sheet metal 0.2-0.8 mm. Corner elements are an angular connection made of plastic, containing mating and connecting elements of the connected profiles.

The technical result provided by the given set of features is to ensure ease and manufacturability of the assembly, providing the possibility, if necessary, of the replacement of components due to the simplicity of the design of the lamp.

The invention is illustrated by drawings, which depict:

in FIG. 1 - assembly diagram of the lamp (general view and in section);

in FIG. 2 - drawings of the corner element;

in FIG. 3 - general view of the lamp;

in FIG. 4 - corner element;

in FIG. 5 - connection of the corner element and the profile;

in FIG. 6 - corner connection;

in FIG. 7 - surface mount;

in FIG. 8 - pendant mount;

in FIG. 9 - fastening rack ceiling and grilyato;

in FIG. 10 - mount on the cable tray.

The LED lamp consists of a base 1, a diffuser 2, an angular element 3 and profiles 4 (Fig. 1). The base is attached to the profiles with screws 5.

The corner element consists of docking elements 6 containing protrusions and tides 7, providing a fixation density in the profile, guides for installation in the profile and grooves 8 for installing the diffuser (Fig. 2). The corner element contains mating and connecting elements of the connected profiles.

The light diffuser 2 is a sheet of translucent polymer. The material used is mainly a lighting sheet of polystyrene or polycarbonate with textured embossing on one side (for example, honeycomb, microprism, crushed ice, semolina, opal, etc.).

Corner element 3 is made of a polymeric material, mainly from ABS plastic, by injection molding.

Base 1 is made mainly of sheet metal, mainly of galvanized or smooth sheet, with a protective polymer coating of the RAL color range, 0.2-0.8 mm thick, widely used in industrial production.

The sides are a long aluminum profile that is widely used in industrial production, in particular window, in the manufacture of mosquito nets, flat on the outside and equipped with at least one longitudinal groove (groove) located along the edge of the profile. A preferably widespread size profile of 25 (± 2) × 10 (± 2) mm is used, white. Also, the profile can be made of polymeric material and have several grooves (grooves).

LED boards can be made of aluminum or fiberglass with a thickness of 0.5 to 2 mm. The boards are equipped with LEDs, mainly SMD components. The boards are mounted on the base in several rows, using double-sided adhesiveless (baseless) tape with a thickness of 50 to 200 microns, which ensures high heat transfer from the board to the case.

The power supply is small-sized, located inside the housing, both on the side wall of the profiles and on the base of the lamp. This arrangement allows the use of luminaires both in the overhead version (mount on any flat surface) with holes in the corners (Fig. 7), and in various other options, such as a suspended mount (Fig. 8), mount on a rack ceiling and grilyato (Fig. 9), mounting on a cable tray (Fig. 10).

The inventive design of the lamp provides simplicity, manufacturability, low weight and sufficient rigidity. The possibility of using materials and parts widely available in the acquisition does not require special technological equipment of production.

The novelty of the design of the claimed utility model consists in the use of an angular connection for mechanical fastening of hollow metal and polymer profiles at an angle of 90 °, which allows to obtain various frames of predetermined linear dimensions and the universality of fastening of LED lamps.
