Description

The technical field to which the utility model belongs

The utility model relates to lighting engineering, namely to wall-ceiling lamps with semiconductor point light sources located in a row or in a strip. The predominant use of the utility model for lighting corridors, stairwells, entrances to apartment buildings and other housing and communal services (hereinafter referred to as housing and communal services).

State of the art

Currently, there is a tendency in the housing and public utilities sector to completely replace lamps with gas-discharge lamps and incandescent lamps with LED lighting devices, which is due to the high luminous efficiency of LEDs with minimal energy consumption, long service life and the absence of special operating and disposal conditions, i.e. environmental safety.

Known light-emitting diode lamp, made by Volzhsky Lighting Engineering Plant LLC, patent RU 151866, IPC: F21S8 / 00, publ. 04/20/2015, containing an elongated heat-conducting body, open on one side, in the cavity of which a driver for powering LEDs and a heat-conducting bracket with lines of LEDs placed on its outer convex surface are installed, the body cavity is closed from above with a diffuser made of a light-permeable material.

Known LED lamp, patent RU 2622285, IPC: F21S4 / 00, publ. 06/14/2017, containing an elongated housing made of a heat-dissipating polymer composite with a longitudinal cavity, fixed to the housing of the LED array and a power supply for LEDs located in the housing cavity. The body cavity is closed from above with a trough-shaped diffuser.

Known housing and communal services luminaire containing a heat-conducting housing with a niche for placing LEDs and covering the niche optically transparent diffuser (patent RU 91136 U1, IPC: F21S4 / 00, publ. 27.01.2010).

In all of the aforementioned designs, the light sources, the power supply and other components are housed in a housing cavity, closed from above by a diffuser. Such lamps can be installed only on a leveled and prepared surface. In the case of using the aforementioned LED devices to replace the fluorescent lamps widely used in the housing and utilities sector, in particular the LPB-01-11, LPB-31-11 lamps and their analogues, it will be necessary to completely dismantle the old lamps with the removal of the fixing elements, the so-called mounting strips. However, the removal of the latter is often accompanied by the destruction of the supporting structures (walls, ceilings), on which these strips were fixed, which leads to the need for repair and restoration work and requires additional costs and time.

Known lighting device (see patent for utility model RU 77023, IPC: F21S8 / 00, publ. 10.10.2008), which has an open longitudinal cavity on the back side, allowing you to hide the old mounting strips, thereby eliminating the need to remove them. This lighting device is taken as the closest analogue to the proposed technical solution.

The lighting device according to the patent RU 77023 is a linear LED lamp, which is characterized by the following features similar to the essential features of the proposed technical solution, namely: the presence of an elongated base with an open longitudinal cavity on the back side formed by the convex shape of the base; the presence of LEDs installed on the front surface of the base and a cover-diffuser covering them, the presence of a power supply unit for LEDs located in the open cavity of the base.

In the aforementioned known structure, the base is made in the form of a U-shaped curved aluminum profile, to which legs with holes for fasteners are fixed at the ends, the diffuser cover is made in the form of an arcuate curved piece of polycarbonate, while the body is formed by the base and shade-diffuser, closed at the ends with side covers.

The disadvantages of the closest analogue include a relatively complex and low-tech housing design, including a large number of dissimilar elements, and, as a consequence, laboriousness of manufacturing and assembling the lamp.

The claimed utility model is aimed at improving the manufacturability of the design of the lamp and simplifying its manufacture.

The achieved technical results, which ensure an increase in the manufacturability of the design, are to reduce the number of structural elements, simplify the tooling used for their manufacture, and simplify assembly.

Disclosure of the essence of the utility model

The above technical problem is solved and the results are achieved due to the fact that in a LED lamp containing an elongated base with an open longitudinal cavity on the rear side formed by the convex shape of the base, LEDs are installed on the front surface of the base and a cover-diffuser covering them, and a unit is placed in the said cavity power supply of LEDs, according to the claimed utility model, the base and diffuser cover are made in the form of parts identical in shape and size, having a convex upper surface, closed along the perimeter side walls connected to the upper surface with a stepped transition, and through holes for fasteners.

Unlike the closest analogue, the body of the proposed luminaire is formed of only two structural elements: a base and a diffuser, having a convex upper surface, side walls closed along the perimeter connected to the upper surface by a stepped transition, and through holes for fasteners.

The term "top" is adopted conventionally and denotes the surface of the part farthest from the support.

Identity of the shape and size of the base and the diffuser shade allows using the same (identical) matrix for their manufacture.

Usually, equipment and accessories are the most expensive item of expenditure, and a reduction in its quantity, unification, will significantly reduce production costs as a whole, which will have a positive effect on the cost of the lamp.

The identity of the shapes and sizes of the parts contributes to the simplicity and accuracy of the assembly of the lamp.

A stepped transition forms a ledge along the perimeter of the parts, a step that performs the functions of a supporting surface when placing parts on top of each other (this design feature of parts can be used to stop them during production and / or storage).

The holes for the fasteners in the parts installed on top of each other are aligned with high accuracy, which ensures simplicity and ease of installation of fasteners, which, when tightened, firmly connect the luminaire body parts to each other and, at the same time, fix the luminaire to the supporting surface.

The base part is preferably made of a heat dissipating polymer composite. Part of the diffuser cover is made of a translucent material, preferably impact-resistant polycarbonate.

For the manufacture of such parts, the injection molding method can be applied. This does not exclude the possibility of using other methods (methods), known or newly discovered, allowing to form parts of the mentioned shape.

In a preferred embodiment of the utility model, the front surface of the base and the diffuser shade is smooth, and the rear surface is corrugated.

The corrugation on the rear (inner) surface of the diffuser shade forms a multitude of small lenses that ensure uniform light flux diffusion. Smooth front (outer) surface of the diffuser contributes to less contamination of the luminaire and better performance of the luminaire.

For the base, the presence of corrugation serves as a decorative element.

It is advisable to make a longitudinal cavity of the base with dimensions not less than 300 mm - length, 55 mm - width and 20 mm - depth. Such dimensions of the open cavity on the back of the luminaire (base) make it possible to hide in it practically any known mounting plate together with mounting pins, in the case of using the proposed luminaire to replace linear fluorescent lamps of the LPB-31-11 type and their analogues.

Ready-made LED strips can be used as LEDs.

Preferably, the luminaire is equipped with motion and light sensors capable of controlling the supply of voltage to the LEDs. In order to increase anti-vandal protection, the luminaire can be equipped with anti-theft plugs covering the holes for fasteners.

Brief Description of Drawings

The claimed technical solution is illustrated by an example of a specific implementation and drawings, which show:

figure 1 is a lamp, general view, volumetric projection; figure 2 - also, bottom view;

figure 3 - lamp, top view with the removed cover-diffuser;

in fig. 4 - lamp, side view with a partial section;

in fig. 5 is a fragment from FIG. 4, increased;

in fig. 6 - the process of assembling the lamp is illustrated;

in fig. 7 and 8 show a luminaire mounted on a supporting structure, over the mounting strip of a replaced luminaire.

The LED lamp, the general view of which is shown in FIG. 1-2, has a body formed from two identical in shape solid-cast thin-walled parts: base 1 and diffuser cover 2.

Each part has side walls: longitudinal (a, b) and transverse (c, d) interconnected along the perimeter by radial transitions f, a convex upper surface s, connected to the side walls by a stepped transition, forming a ledge k along the perimeter of the part (see Fig. . 1 and 3).

On the edges of the base 1 and the diffuser cover 2 there are through holes 3 for fasteners. In the area of the holes on the rear side of the parts, bosses 4 can be formed (see Fig. 2).

For the manufacture of the base 1 and the diffuser-diffuser 2, the same or identical matrixes are used - forms, which can significantly reduce the costs of preparing for production and production of lamps, since tooling is the main cost item.

The base part 1 is made of a heat-dissipating polymer composite, due to which the base acts as a radiator and provides heat dissipation.

Part of the diffuser cover 2 is made of translucent material, preferably impact-resistant polycarbonate.

The back surface of parts 1 and 2 is corrugated. The corrugation forms a set of small lenses on the rear (inner) surface of the diffuser-plafond 2, providing uniform diffused illumination. For base 1, the corrugation is a decorative element.

On the front, smooth surface of the base 1, light sources are installed - LEDs 5, which can be used as ready-made LED strips (see Fig. 3). The LED strips are fixed to the front surface of the base 1 with a tight thermal contact, for example, by means of plastic rivets or heat-conducting adhesive material.

On the back (back) side of the base 1, due to its convex shape, there is a longitudinal cavity 6, open to the back side of the lamp (see Fig. 2, 4).

In cavity 6 there is a power supply unit (driver) 7, which converts the voltage of the 220V network into the voltage required for the normal functioning of the LEDs. Placing the power supply unit 7 in an open cavity facilitates its maintenance and provides the possibility of quick replacement. When installing the power supply, they try to eliminate "long wires" by placing it on one of the extreme sections of the cavity 6.

The diffuser cover 2 is installed with support on the ledge k of the base 1 (see Figs. 5, 6), while the identity of the shapes and sizes contributes to the tight fit of the parts and the "alignment" of the fastening holes 3 of the parts, i.e. their placement on the same axis.

To eliminate the displacement of parts during assembly, glue can be applied to the bosses 4 of the diffuser lamp 2. The final connection of the parts of the lamp is carried out when it is fixed to the supporting structure with fasteners 8 installed in the coaxial holes 3 of parts 1 and 2.

To prevent accidental or deliberate unwinding in the holes 3 of the diffuser cover 2 over the fastening elements 8, the heads of which are recessed in the holes, anti-theft plugs (not shown in the drawings) can be inserted.

The electrical circuit of the luminaire can include presence and light sensors that control the power supply circuit of the LEDs and exclude the operation of the luminaire during daylight hours and in the absence of a person.

The dimensions of the longitudinal cavity 6 are preferably: length - not less than 300 mm, width - not less than 55 mm and depth - not less than 20 mm.

In the case of using the proposed LED luminaire to replace the linear fluorescent lamps LPB-31-11 and their analogs widespread in the housing and utilities sector, the mounting plate of the fluorescent lamps remains on the bearing surface (not dismantled). The proposed LED luminaire is installed on the supporting surface 9 directly over the left (not dismantled) mounting strip 10, which is hidden together with the mounting pins 11 protruding from it in the open cavity 6 on the back side of the luminaire, which has appropriate dimensions (see Fig. 7 - 8) ...

The lamp contains a motion sensor and an illumination sensor (not shown in the drawings), configured to control the supply of voltage to the LEDs.

The proposed luminaire has a simple design with a minimum number of parts, characterized by high adaptability to manufacture and assembly.

The luminaire can be used for both ceiling and wall installation.
