Description

Technology area

The utility model belongs to the field of lighting technology, to the class of pendant lamps for fixed installation using light-emitting diodes as light sources. The utility model is intended for street, indoor, industrial, domestic lighting and is an alternative, including for traditional lamps such as "Bell" or in the English name "High bay light" (literally from English. High-rise light fill).

State of the art

The prior art for the area under consideration is characterized by two main directions of constructive solutions for such lamps and their combination.

Direction 1. These solutions are characterized by the use of a monolithic body-radiator made of heat-conducting material, to which the remaining parts of the luminaire are mounted - one or more LED modules, a translucent screen, and fastening elements.

Known analogues, representatives of this direction LED lamp CN 213299999 U, F21V 14/06, 2020.11.02; Housing-radiator for a LED lamp, LED lamp and how to use them (original name HEAT-SINK FOR HIGH BAY LED DEVICE, HIGH BAY LED DEVICE AND METHODS OF USE THEREOF), US 9581322 B2 F21V 29/77, F28F 13/18 , F2IV 29/74, F2IY 101/00, 2017.02.28. The disadvantage of such solutions is the limited scope of their application, due to the impossibility of scaling in wide ranges of light characteristics, as well as increased requirements for the technical equipment of the production and technical base for their manufacture, primarily due to the use of the technology of casting aluminum alloys.

Direction 2. In luminaires of this direction, the radiator housing is made of composite elements, as a rule, from elements of a stretched aluminum profile, which allows flexible control of the configuration of the luminaire for the needs of a specific case of its use. The use of extrusion technology in the manufacture of housings makes it possible to increase the manufacturability of the manufacture of lamps in comparison with solutions in direction 1, to reduce the requirements for the technical equipment of production.

Known analogue, representative of direction 2, LED lamp RU 195775 U1, F21S 13/10 (2006.01), 2018.11.02. The luminaire contains one or several housings that house light sources in the form of LEDs and the necessary electromechanical equipment. Each housing contains a light diffuser made of polycarbonate and performing protective and light distribution functions. The LEDs are located under the diffuser, in one or more rows, on the LED bar. The housings are integrated using a housings connector designed to connect the luminaires to the lighting module. On the connector of the housings, docking elements are made, located on two opposite sides, with the formation of a profile in the form of a symmetrical figure, with the formation on each side of a bowl-shaped U-shaped contour, designed to interact with a figured groove of a reciprocal shape made in the housing, along the entire its length. The lighting module is formed using the body connector. In this case, the number of luminaires involved in the module depends on the required lighting power, the concentration of the resulting luminous flux, the area, shape and size of the illuminated zone. The disadvantage of the described technical solution is the need to use an expanded range of body connectors for different configurations of luminaires, the complication of assembly operations during manufacture, increased overall and mass characteristics for high power luminaires.

Known analogue, representative of a combination of technical solutions in areas 1, 2 Lamp with interchangeable fastening elements (original English name, BAY LUMINAIRE WITH INTERCHANGEABLE HOUSING COMPONENTS), US 10132 475 B2, F21V 17/00, F21V 29/505, F21V 29/507 , F21V 29/76, F21V 15/01, F21S 8/04, F21Y 115/10, 2018.11.20. The luminaire contains both a monolithic radiator and a housing for placing electromechanical equipment. In this case, the body is made of a composite of interchangeable components and elements of their connection, also interchangeable and made by the extrusion method. The specified technical solution allows to reduce the material consumption of the radiator, since the functions of heat removal and placement of the electromechanical equipment of the luminaire are separated by separate components. However, the manufacturability of such products is inferior to analogs of both the 1st and 2nd directions.

As an analogue of the proposed solution, the closest of the indicated ones was adopted - LED lamp according to patent RU 195775 U1, F21S 13/10 (2006.01), 2018.11.02.

The technical task of the proposed solution is:

- creation of a luminaire with the possibility of its flexible configuration for the required luminous flux power;

- creation of a luminaire focused on mass production with a minimum staff of workers, minimum requirements for their qualifications, as well as minimum requirements for the technical equipment of production.

The technical result of the proposed solution is:

- expanding the arsenal of technical means of similar application,

- improving the manufacturability of a lighting product.

The essence of the claimed utility model

The technical result is achieved through the implementation of a composite structure of the radiator of the same drawn profiles, fixed from the ends by connecting the light module to the light board from the front end and connecting to the back cover at the rear end.

Thus, a rigid structure is realized, fixed on two opposite sides, and, in comparison with the prototype, no connection and additional radiator connectors are required directly to each other along their length. At the same time, due to the use of identical drawn profiles, only one section profile is required for the manufacture of products, and several times smaller than the profile of the assembled product, which allows the use of available equipment both for the manufacture of the profile itself (extruders with less force), and for procurement works (cutting saws of lower power).

The back cover plays the role of the main bearing power unit, simultaneously performing the functions of fastening or suspension in the places of installation of the product, fastening the power source of the lamp, fastening, interconnected light board with a translucent screen with lenses of the light module, radiators.

For decorative purposes, a plastic cap made of polycarbonate is used, which covers the radiators and the power source and is fastened to the rear cover along the rear end of the lamp radiators together with the radiators, which makes it possible to implement a product with different design solutions in shape and color and to exclude painting operations and additional machining in the case of using aluminum alloys.

The technical result in terms of expanding the arsenal of technical means of similar application is realized by changing the height of the ribs, i.e. profile length and number of LEDs. In this case, in the case of a reduced power of the luminous flux and a corresponding decrease in the length of the height of the ribs, the light part is recessed into the inner cavity of the plastic cap, due to which an additional light-shielding angle is formed.

The listed features of the manufacture of components and assembly of the product ensure the implementation of the technical result in terms of improving the manufacturability of the lighting product.
