The disadvantages of the known devices is the inability to quickly repair them directly at the installation site without complete dismantling.

The technical result, which the utility model aims to achieve, is to increase the maintainability of the LED lamp.

Achieving reliable thermal contact between the heat exchange surfaces of the driver and the housing, and improving the conditions of heat removal from the surface of the driver.

Also, an increase in the service life of the LEDs and the power supply is achieved by increasing the heat transfer of the outer surface of the case and, as a result, reducing the metal consumption of the case.

The inventive device consists of the following elements:

1 - case-radiator;

2 - the back cover of the radiator case;

3 - printed circuit board with LEDs;

4 - fasteners;

5 - a clamping ring;

6 - compound;

The inventive LED lamp (Fig. 1) has a detachable modular design connected by fasteners.

The lamp consists of a housing, which also serves as a cooling radiator (housing-radiator 1) for a printed circuit board 3 with LEDs, driver.

Effective cooling is achieved by dividing the case-radiator 1 into two parts.

The case-radiator 1 consists of two parts, one of which is a cover-radiator 7, in which the driver 13 is installed.

The radiator cap 7 is configured to be completely detached from the radiator housing 1.

In this case, the radiator cap 7 is preferably located in the lower part of the radiator housing 1.

The LEDs on the printed circuit board 3 are cooled by the housing-radiator 1, which additionally has two ventilation holes 16 in the nose of the lamp for ventilation.

The radiator case 1 is closed by a back cover 2, which is fixed with screws.

In the case-radiator 1, a printed circuit board 3 with LEDs is installed, on top of which secondary optics 12 of LEDs are placed to form a light intensity curve (KSS), which, in turn, is closed by a protective screen 9.

On the body-radiator 1 at the edges of the fit of the protective screen 9 is placed seal 10.

The seal 10 lies in the channel, made in the form of a recess on the housing-radiator 1.

As a protective screen 9, tempered glass is used, which is fixed using the clamping ring 5 and screws from the inside of the radiator case 1 above the printed circuit board 3.

Installation takes place sequentially from the bottom up: the board-optics-glass.

The driver 13 is installed directly in the radiator cap 7, which is a detachable part of the lamp.

The radiator cap 7 contains a reservoir for laying the driver 13 and filling it with compound 6.

Compound 6 is poured into the reservoir of the radiator cap 7 with the driver 13 installed in it.

In this case, the driver 13 is securely fixed and sealed in the radiator cap 7 by pouring the compound 6.

The radiator cap 7 is fixed to the radiator housing 1 with two fasteners 4, which, in turn, are fixed to the radiator housing 1 with springs 8.

Also, the radiator cap 7 is fixed with the rear cover 2 through a cylindrical hinge joint 17.

The electrical contact of the driver 13 with the LEDs on the printed circuit board 3 and with the power supply network is carried out through terminals 14 of the type "plug-socket".

Sealing the compartment with the terminals 14 and the driver 13 is achieved by means of the seal 11 of the radiator cap 7.

The luminaire is installed and fixed on the pole by means of two clamps 15, which are used as screws and hex nuts.

The main advantage when working with a luminaire installed at a high height is that the radiator cap 7 with driver 13 is easily disconnected from the radiator casing 1 (even when the lamp is on) - “hot swap”.

When removing the radiator cap 7, the rear cover 2 is not removed, i.e. together with the driver 13 you do not need to disconnect the wires, because this connection is made as a “plug-socket”.

Those. it is enough to unfasten the mechanical fasteners 4 and at the same time, the terminals 14 are disconnected.

Also, when reinstalling the radiator cap 7, a connection of terminals 14 occurs.

At the same time, the luminaire remains on a pole connected to a common power source, which allows the rest of the luminaires to work and does not require disconnecting the entire network.

Another difference is the ability to install various sensors on the lamp, for example, a light sensor.

For this, the radiator cap 7 can be equipped with an external socket for installing the sensor without using screwdrivers and wires, while the sensor is fixed by twisting it into the socket half a turn.

When the lamp power is more than 100W, heat from the LEDs is intensively transferred to the driver 13, which leads to its undesirable heating.

To eliminate this, the driver 13 is isolated from contact with the part of the lamp where the LEDs 3 are installed.

Those. LEDs and driver 13 have different heatsinks that do not touch each other.

The LED lamp is compact, convenient in operation, allows you to increase the brightness of the light-optical unit, simplify installation due to the ease of design and increase its durability due to tightness, can be used both in dry rooms and in rooms with high humidity.

The driver 13 is made in a compact form, does not contain a box for the driver board.

The inventive LED lamp has the following advantages:

- reduction of weight and size parameters of the lamp (compactness);

- use of the driver as a cooling radiator of the lamp housing;

- uniform distribution of heat from the driver 13 throughout the housing-radiator 1 of the lamp due to the filling of the driver 13 with compound 6, because the place of contact of the driver 13 with the compound 6 and the radiator cap 7 becomes monolithic;

- increase the explosion protection of the lamp due to the sealing of the driver 13 from aggressive environmental influences by filling the entire driver 13 with compound 6 (since the electrical equipment (driver) that can ignite an explosive atmosphere due to sparking or heating is contained in compound 6, as a result of which the explosive atmosphere cannot catch fire);

- ensuring the vandal resistance of the lamp due to the sealing of the driver 13 by pouring with compound 6, while in addition, the housing-radiator 1 of the lamp serves as a rigid shell.

This improves the performance of the lamp by eliminating overheating of the printed circuit board, improving the temperature regime of the LEDs, increasing the efficiency of heat removal from the printed circuit board.

EFFECT: increased technological effectiveness of fixing the protective screen 9 in the radiator case 1, which simplifies and accelerates the assembly of the LED lamp.

The advantages of the claimed device is ergonomics and simplicity of design, ease of installation, low weight, compactness, maximum light output, reduced power consumption.

The inventive utility model can be used for outdoor and indoor lighting for various functional purposes (utilitarian, architectural, artistic, lighting advertising and others), in particular, streets, roads, infrastructure of transport hubs, territories of production, storage and other premises, parking lots, gas stations, squares, courtyards, railway stations, platforms and bridges, alleys, squares, parks, highways and motorways, sports grounds, as well as pedestrian and walking areas, etc. P.
