Description

The utility model relates to lighting devices and is intended for lighting highways, roads, streets, squares, courtyards, tunnels, industrial premises, etc.

Currently, various LED light sources are widely used in the market of lighting products, which actively compete with products based on incandescent lamps, fluorescent and halogen lamps.

In particular, from RF patent No. 105968, class F21V 1/00, published on June 27, 2011, an LED lamp is known that includes a housing in which LEDs are connected to the power supply, while the housing and the circuit board are made of aluminum, the sealing material is light-conducting compound, which is poured at the level of the LED, the cover is a protective glass made of polycarbonate, while the housing is prefabricated.

The disadvantages of this famous LED lamp is the low reliability due to the need to use special elements for mounting the lamp.

From the patent of the Russian Federation No. 118398, class F21S 13/00, published July 20, 2012, there is a device for an LED lamp comprising a housing, at least two matrixes of LEDs mounted on printed circuit boards and a power supply installed in it, the housing being made in in the form of a segment of a metal profile made of heat-conducting material with a compartment for the power supply unit, a compartment for the placement of LED arrays and with fixture fixtures for various operating conditions, and above the LEDs there are optical transparent lenses of the secondary optics , The compartment under the power unit is provided with a protective casing of a metal printed circuit boards are made with substrates of thermally conductive material, and between the optically transparent lenses of secondary optics located sealing material filling the space between the LEDs and the body portion is provided with heat-ribs.

The disadvantages of this design include the complexity of the design.

From RF patent No. 102748, class F21S 13/00, published September 28, 2010, a LED lamp is known that contains a housing, at least two LED arrays and a power unit installed in it, the housing being made of heat-conducting material with a compartment under the unit power supply, a compartment for the placement of LED arrays, made profiled, and made on the housing by elements for mounting the lamp in various operating conditions, the housing being made in the form of a segment of a hollow metal profile consisting of a U-shaped compartment and for placing a light source on high-power LEDs, compartments for accommodating LED power supplies and a cylindrical compartment for mounting a lamp on the console tube of the lighting support, while on the outer surface of the compartments for placing high-power LEDs and power sources, heat-removing fins made of the same material are placed, increasing the surface area of the lamp.

This technical solution was adopted as the closest analogue.

Its technical and constructive drawback is the implementation of the housing in the form of a single monolithic part, which significantly reduces the heat sink efficiency, despite the presence of heat sink fins, which ultimately reduces the reliability of the lamp.

The technical result, for which the claimed utility model is intended, is to increase the efficiency of heat removal and, accordingly, the reliability of operation of the lamp.

Achieving the indicated technical result is ensured by the fact that the claimed LED lamp comprises a housing with compartments for accommodating light sources and a power supply unit, optically transparent glass or without it, covering the LED light sources, means for attaching the housing to a supporting surface, while the housing consists of two components parts, one of which forms a compartment for accommodating LED light sources, and the other a compartment for their power supply, while these parts are separated by an air gap, and h part of the housing, forming a compartment for LED light sources, is equipped with heat-removing fins, decreasing in height from the center to the periphery and located on its upper outer surface.

The design of the LED lamp is shown in figure 1.

The lamp housing consists of two interconnected parts. Part 1 forms a compartment for accommodating a power supply unit of 5 LED light sources. Part 2, in turn, forms a compartment for the placement of LED light sources 7. Parts 1 and 2 of the housing are separated from each other by an air gap 3, the presence of which and its blowability determine that the LED light sources will not heat the block placed in part 1 of the housing power 5, which is sensitive to heat above 45 ° C.

On a top surface of part 2, heat-removing ribs 4 are arranged with a certain pitch, the needles of which are made semicircular, and the ribs themselves are decreasing in height from the center to the periphery. This embodiment, as well as the location of the ribs above the LED light sources, provides on the one hand optimal heat dissipation, and on the other hand, optimal access to laminar air flows without forced ventilation.

The compartment with the LED light sources housed in it can be covered with an optically transparent protective glass 6. The design of this compartment is characterized, in particular, by the following features and capabilities: the ability to use sealing with glass (with / without lenses, including single ones with a protective mask and group without sealing systems); the possibility of using a transparent compound as a sealant (with and without glass); the possibility of using a lens without protective glass such as Ledil Ctrada with the achievement of sealing type IP 65; the use of special cable entry systems that counteract the formation of condensate; the possibility of using wires containing silicone rubber, allowing the lamp to be operated at temperatures in the range from -60 to + 180 ° C.

Parts 1 and 2 of the housing themselves, together with glasses of various lengths, are a constructive combination of units and parts, with which you can assemble lamps for various purposes - street and industrial, as well as floodlights; lamps of various power; luminaires with different KSS (light intensity curve).

The lower part 2 of the housing has lateral grooves (not shown in FIG. 1) for attachment means that allow the parts to be connected together in series with the formation of the module and fastened to the remote bracket.
