The above analogues of luminaires contain two closed contours in cross section: the contour of light sources formed by the profile of the casing and a protective translucent element; and a power source circuit formed directly by the profile of the luminaire body itself.

A common drawback of such solutions is the unfavorable operating conditions of the power sources, since they are located on the same heat-conducting base as the light sources, including in cases (RU 154 191 U1 / RU 154 192 U1) when the power sources are not directly on the same heat-conducting base, but are in common with it a closed space. In addition, in this case, the efficiency of heat removal from the light sources is reduced, since the power sources block the air flow distribution channel.

Another drawback of the above analogues is the insufficient efficiency of the lamp housings as a radiator: approximately the same distribution of the body material (over the cross section) in the area of light sources and far from them leads to the fact that the heat-conducting material at the periphery “does not work” due to the large heat path flow from light sources.

The known solution of the LED lamp (options) RU 2 511 564 C1, F21V 29/00, H01L 33/64, 09/17/2012 (the solution is chosen as a prototype), in which this disadvantage is eliminated by optimizing the thermal area and the impact of air flow in the zone heat dissipation. The technical result is achieved by the fact that the lamp radiator is made of several flat plates of different heights, made of a material having high thermal conductivity (aluminum, copper, etc.), installed so that their heat-conducting path is as short as possible. As a result, heat from light sources is transferred to a heat-conducting base, “stretched” over its entire area, and then transferred to a radiator.

The disadvantages of this solution are the lowered efficiency of heat dissipation due to the presence of thermal barriers in the area of connection of the plates and the heat-conducting base, as well as the increased cost of manufacturing a lamp due to the need to assemble the housing from these elements and manufacture these elements. In addition, the implementation of the mounting assembly of the lamp for its mounting and fastening of the power source will also lead to the need for assembly and installation work and, as a result, to an increase in the complexity of its manufacture.

The technical task of the claimed group of utility models is:

- further optimization of the heat dissipating abilities of the lamp housing in order to reduce the weight, dimensions, and material consumption of the lamp;

- reducing the complexity of manufacturing a lamp in order to reduce the time and cost of manufacturing a lamp;

- expanding the scope of the lamp in order to solve the spectrum of lighting problems using one model of the lamp.

The total technical result is: a decrease in the mass, dimensions and material consumption of the lamp.

Utility Model Group Essence

The essence of the claimed group of utility models is to solve:

1) a radiator case made of heat-conducting material in the form of a drawn symmetrical profile, in which the massive heat-conducting base and the ribs directed from the base are made together, and each subsequent bent pair of arcuate fins, starting from the central one, reduces the cross-section of the heat-conducting base by the thickness of the rib, while the ribs are made with a wavy surface.

This solution of the lamp housing eliminates the disadvantages of the prototype: thermal barriers are eliminated, assembly work on the connection of the radiator plates is eliminated; arcuate fins with a wavy surface increase the area of the radiator and additionally turbulize the air flow, increasing the efficiency of the radiator; the drawn-out housing solution makes it easy to scale the lamp;

2) additional load-bearing components: profile-pipe, profile-plate - for the possibility of using a lamp with the same radiator body, both in a suspension or ceiling, and in a console (mounting on a pipe) versions, also implemented as a drawn profile . Moreover, the latter can also be made of heat-conducting material, but do not directly participate in heat dissipation and are used only in those cases and in those places of the radiator case where they are needed.

This solution allows you to "untie" and effectively solve the problems of heat dissipation and the implementation of the bearing functions of the housing, as well as to eliminate unreasonable consumption of material of the housing, due to the stretched performance of its structural elements;

3) additional elements of the casing-radiator: a pair of vertical struts extending from the heat-conducting base in the opposite direction, at the end of which U-shaped mounting channels are made to accommodate the mating parts of the bearing components - profile pipes and / or profile plates, and connected with a central bent pair of arcuate ribs with the formation of symmetrical closed loops between the uprights and the central pair of ribs.

A pair of symmetrical closed end-to-end contours allows to ensure the rigidity of the connection of the casing-radiator with the profile pipe and / or profile plate and to exclude the "opening" of the vertical posts under the action of the load.

The central end-to-end closed loop formed by the body-radiator and the profile-plate or profile-pipe and / or profile-plate and profile-pipe allows isolating the power source from the heat-conducting base, since the latter is located on the outside of the additional profiles that are “decoupled” relative to radiator case.

The luminaire according to the first embodiment includes at least one LED or LED module with fastening elements to a heat-conducting base, made in the form of an LED COB matrix (COB - chip on board, "chip on board") or in the form of COB- matrices with integrated optics; a radiator case made of heat-conducting material in the form of a drawn symmetrical profile, in which the massive heat-conducting base and the ribs directed from the base are made together, each subsequent bent pair of arcuate ribs, starting from the central one, reduces the cross-section of the heat-conducting base by the thickness of the ribs, while the ribs themselves are made with a wavy surface, as well as a pair of vertical posts, made in conjunction with the radiator case, extending from the heat-conducting base in the opposite direction, on At the end of which U-shaped fixing channels are made with longitudinal risks on the outside to accommodate the mating parts of the profile plate with screws for longitudinal risks and connected to a central bent pair of arched ribs with the formation of symmetrical closed loops between the uprights and the central pair of ribs and a central closed loop formed by a radiator body and a profile plate having longitudinal risks on the outside; a power source located on the outside of the central closed loop and fixed with screws on the longitudinal risks of the profile plate; side decorative covers with a profile corresponding to the profile of the body-radiator and profile-plate.

The luminaire according to the second variant incorporates at least one LED or LED module with fastening elements to the heat-conducting base, made in the form of an LED COB matrix (COB — chip on board, “chip on board”) or in the form of COB- matrices with integrated optics; a radiator case made of heat-conducting material in the form of a drawn symmetrical profile, in which the massive heat-conducting base and the ribs directed from the base are made together, each subsequent bent pair of arcuate ribs, starting from the central one, reduces the cross-section of the heat-conducting base by the thickness of the ribs, while the ribs themselves are made with a wavy surface, as well as a pair of vertical posts, made in conjunction with the radiator case, extending from the heat-conducting base in the opposite direction, on At the end of which U-shaped fixing channels are made with longitudinal risks on the outside to accommodate the mating sections of the profile pipe with screws for longitudinal risks and connected to a central bent pair of arcuate ribs with the formation of symmetrical closed loops between the uprights and the central pair of ribs and a central closed loop formed by a radiator body and a profile pipe having an inverted T-shaped groove on the outside; a power source located on the outside of the central closed loop and fixed on the T-groove of the profile pipe; side decorative covers with a profile corresponding to the profile of the radiator body and profile pipe.

The luminaire according to the third embodiment includes at least one LED or LED module with fastening elements to the heat-conducting base, made in the form of an LED COB matrix (COB — chip on board, “chip on board”) or in the form of COB- matrices with integrated optics; a radiator case made of heat-conducting material in the form of a drawn symmetrical profile, in which the massive heat-conducting base and the ribs directed from the base are made together, each subsequent bent pair of arcuate ribs, starting from the central one, reduces the cross-section of the heat-conducting base by the thickness of the ribs, while the ribs themselves are made with a wavy surface, as well as a pair of vertical posts, made in conjunction with the radiator case, extending from the heat-conducting base in the opposite direction, on At the end of which U-shaped fixing channels are made with longitudinal risks on the outside to accommodate the counterparts of the profile plate and profile pipe with screws for longitudinal risks, and connected to a central bent pair of arcuate ribs with the formation of symmetrical closed loops between the uprights and a central pair of ribs and a central closed loop formed by a radiator body and together a profile plate and a profile pipe having an inverted T-shaped groove on the outside; a power source located on the outside of the central closed loop and fixed with screws for the longitudinal risks of the profile plate or for the T-shaped groove of the profile pipe; side decorative covers with a profile corresponding to the profile of the body-radiator and profile-plate and the body-radiator and profile-pipe; cover plug profile pipe.

A heat sink body-radiator made of a heat-conducting material in the form of a drawn symmetrical profile, in which a massive heat-conducting base and ribs directed from the base are made together, each subsequent bent pair of arcuate ribs, starting from the central one, reduces the cross-section of the heat-conducting base by the thickness of the ribs, while the ribs themselves made with a wavy surface, as well as a pair of vertical posts made in conjunction with the radiator body, extending from the heat-conducting base in opposite the other side, at the end of which there are U-shaped fixing channels with longitudinal risks on the outer side to accommodate the counterparts of the profile plate and / or profile pipe with screws for longitudinal risks and connected to a central bent pair of arched ribs with the formation symmetrical closed loops between the uprights and the central pair of ribs.

A lamp according to any one of the options, characterized in that it contains a power source having a housing of a drawn profile with fins and upwardly curved ribs on the sides, a base mounted therein also of a drawn profile, on which are based elements for placing printed circuit boards with electronic components and side covers with fasteners and the ability to install standard pressure glands.

This solution also expands the scope of use of the luminaire, since not only the luminaire’s dimensions, but also the dimensions of the power supply increase with the luminaire’s power. Thus, it becomes possible to use different types and capacities of power supplies with a unified case by selecting the length of its case and base. The manufacturing of the power source itself is greatly simplified, since the installation of printed circuit boards with electronic components takes place in an open area. Operating costs are reduced: when the power source fails, the printed circuit board with electronic components is easily replaced, the case is subject to reuse. The body with fins and fins acts as a heat sink for removing heat from the power source, the fins shield the upward heat flux from the lamp. This increases the reliability of the power source and the lamp as a whole.

The implementation of the utility model LED lamp is as follows. Based on a specific lighting task (the necessary illumination, the required radiation pattern) are selected:

- the required number of LEDs or light modules 18, including those equipped with primary or secondary optics (hereinafter referred to as light modules), including high-power LEDs, including LEDs made using the chip on board technology in the form of COB- matrices;

- for the selected number of light modules 18, the corresponding length of the drawn heat-conducting case-radiator 1 is selected, as well as the type and number of power supplies 12.

Light modules 18 during operation emit heat transferred to the massive heat-conducting base 2 of the radiator casing 1, which is uniformly “stretched” over its entire area and freely transferred to the ribs 3 in proportional parts, corresponding to the difference in the thickness of the cross-section of the heat-conducting base 2 and then “removed” from the casing -radiator with an uneven section in the ascending air stream. Curved arcuate ribs 3 enhance the effect of turbulization of the air flow, thereby accelerating the removal of heat from the lamp. Profile plate 7 and / or profile pipe 8 indirectly participate in heat dissipation and to a greater extent perform load-bearing functions, and not along the entire length of the radiator housing 1, but where necessary, which reduces material consumption for the implementation of the lamp extruded type. The power source 12 is placed at a distance from the heat-conducting base 2 by means of vertical posts 4 and profile plate 7 and / or profile pipe 8, which are made separately from the housing-radiator 1. This allows to reduce the thermal load on the power source, as well as to provide free access to the heat-conducting base 2 during the installation of the light modules 18 and directly to the power source itself in the case of servicing the lamp and replacing a failed power source as a component with a shorter life than light modules. Closed circuits between the uprights 4 and the ribs 3 provide the necessary structural rigidity and do not allow the uprights 4 to “open” from the load of external influences when fixing the lamp to a suspension or console. The side covers 16 and 21 are made in accordance with the cross-section of the casing-radiator 1 and the profile plate 7 and / or the profile pipe 8. The covers are end-to-end for free circulation of air flows over the cross section of the casing-radiator 1. Longitudinal risks 9 on the casing-radiator 1 and profile plate 7 greatly facilitate the installation of fasteners 14, 15.

The lamp according to the first embodiment is as follows.

On the heat-conducting base 2, blind holes 10 are cut for mounting the light modules 18 and through holes 11 for supplying power to the light modules 18.

Light (s) module (s) 18 are installed through the thermal interface on the heat-conducting base 2 of the radiator housing 1 and are fixed with screws through pre-cut holes. Next, the wires of the power supply are desoldered and the cable is left for connection with the output from the power supply lead 13. The through holes 11 on the heat-conducting base 2 with the power wires of the light module (s) are sealed with a sealant. The power source also has a pressure seal 13 for connecting to the mains.

After that, the profile plate 7 is mounted by inserting it into the reciprocal U-shaped channels 5 of the radiator case 1 and fixing it with screws 15 according to the longitudinal risks 9 of the radiator case 9 specially provided for these purposes. The cable output from the light modules 18 is connected to the source output supply 12. The latter is mounted on the profile plate 7 and is fixed with screws 14 for longitudinal risks 9.

Next, the side covers 16 are mounted, fixed with screws 20 along the attachment points 6 of the radiator housing 1. The wire is laid in the hole 17 of the side cover 16.

The luminaire is mounted in a suspended version using fasteners (bolts, screws, eyebolts) installed according to the longitudinal risks 9 of the profile plate 7.

The luminaire according to the second embodiment is carried out in a similar way with the only difference that instead of the profile plate 7, the profile pipe 8 is inserted into the radiator body 1. The power source 12 can be fixed to the T-shaped groove of the profile pipe 8.

The lamp according to the third embodiment is also carried out in a similar way, with the profile plate 7 and the profile pipe 8 being inserted into the radiator casing 1. The power supply 12 is fixed to the profile plate 7 with screws 14. The lamp is mounted on the console through the profile pipe 8, fixing is carried out by bolts through the nuts located in the T-slot of the profile pipe 8. To prevent moisture from entering the console through the profile pipe 8, the latter is closed by a plug 22, in which a seal 23 of the power cable is provided. The lamp is closed by side covers 16 and 18 from the side of the profile plate 7 and profile pipe 8, respectively.

The power source contains a base 25 on which printed circuit boards with electronic components are mounted according to the provided base elements. After installation, the base 25 is inserted into the housing 24 of the power source and hermetically sealed with covers 26 with grommet 13 for the power cables. The housing 24 with fins and upwardly bent ribs on its lateral sides are involved in the active dissipation of heat generated during operation of the electronic components of the power source. In addition, the bent upward ribs shield the upward heat flux from the housing-radiator 1 of the lamp.

If the electronic components of the power supply 12 fail (they are the components with the least life from all parts of the lamp), the latter is easily dismantled without disassembling the lamp itself. Next, the covers 26 are dismantled from the housing 24 of the power source, the base 25 with the failed electronic components is pulled out of the housing 24. After which they are replaced and the work is repeated in the reverse order. After mounting the power source 12 on the profile plate 7 or profile pipe 8 and connecting to the terminals from the light modules, the lamp is again ready for operation.
