Description

Technical field

The invention relates to the field of lighting engineering to the class of pendant lamps for fixed installation using light emitting diodes as light sources. The invention is intended for street, indoor, industrial, household lighting and is an alternative, including for traditional luminaires of the "Bell" type or in the English name "High bay light" (literally from English high bay light).

State of the art

The level of technology 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 heat-conducting material body-radiator, to which the remaining parts of the lamp are mounted - one or more LED modules, a translucent screen, fasteners.

Analogues are known, representatives of this direction LED lamp CN 213299999 U, F21V 14/06, 2020.11.02; Radiator Housing for LED Lighting, LED Lighting and How to Use Them , 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 a wide range of light characteristics, as well as increased requirements for the technical equipment of the production and technical base for their manufacture, primarily resulting from the use of aluminum alloy casting technology.

Direction 2. For luminaires of this direction, the body-radiator is made of a composite, usually from elements of an extruded aluminum profile, which allows you to flexibly control the configuration of the luminaire for the needs of a particular case of its use. The use of extrusion technology in the manufacture of housings makes it possible to increase the manufacturability of luminaires in comparison with solutions in direction 1, and to reduce the requirements for the technical equipment of production.

An analogue is known, a representative of direction 2, LED lamp RU 195775 U1, F21S 13/10 (2006.01), 2018.11.02. The luminaire contains one or more housings, in which light sources in the form of LEDs and the necessary electromechanical equipment are placed. Each housing contains a light diffuser made of polycarbonate that performs protective and light distribution functions. The LEDs are located under the diffuser, in one or more rows, on the LED line. The housings are integrated using a housing connector designed to connect luminaires to a 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 cup-shaped U-shaped contour, designed to interact with the figured groove of the reciprocal shape, made in the housing, throughout its length. With the help of the housing connector, the lighting module is formed. At the same time, the number of lamps involved in the module depends on the required lighting power, the concentration of the resulting light flux, the area, shape and size of the illuminated area. The disadvantage of the described technical solution is the need to use an expanded range of housing connectors for different configurations of fixtures, the complexity of assembly operations in manufacturing, increased overall weight characteristics for high power fixtures.

An analogue is known, a representative of a combination of technical solutions in directions 1, 2 Luminaire with interchangeable fasteners (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. At the same time, the body is made as a composite of interchangeable components and elements of their connection, also interchangeable and made by extrusion. The specified technical solution allows to reduce the material consumption of the radiator, since the functions of the heat sink and the placement of the electromechanical equipment of the lamp are separated into separate components. However, the manufacturability of such products is inferior to analogues of both the 1st and 2nd directions.

As an analogue of the proposed solution, the closest of the indicated ones is 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 lamp oriented to 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:

- expansion of the arsenal of technical means of similar application,

- improving the manufacturability of lighting products.

The essence of the invention

The technical result is ensured by the implementation of a composite structure of the radiator from identical drawn profiles fixed at the ends by connecting to the light board of the light module - from the front end and connecting to the rear cover - at the rear end.

Thus, a rigid structure is implemented, fixed on two opposite sides, and, in comparison with the prototype, it is not required to connect and additional radiator connectors directly to each other along their length. At the same time, due to the use of the same drawn profiles, for the manufacture of products, a profile of only one section is required, 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 effort), and for procurement work (cut-off saws of lower power).

The back cover acts as the main load-bearing power unit, which simultaneously performs the functions of fastening or suspension in the places where the product is installed, fastening the power source of the lamp, fastening the interconnected light board with a translucent screen with light module lenses, radiators.

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

The technical result in terms of expanding the arsenal of technical means of a similar application is implemented 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 internal 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 provide the implementation of the technical result in terms of improving the manufacturability of the lighting product.
