LED lighting devices have become widespread due to their inherent advantages - high luminous efficacy, low power consumption, long service life, high safety level, compactness and low weight, resistance to mechanical stress, light purity, radiation directivity, etc.

Known LED lamp containing a housing, inside of which are located: LED board, driver, light diffuser and heat exchanger having channels formed by rings and located around the axis of the housing, which form a heat exchange part to remove air heated by LED (RF patent No. 167546 for the utility model "LIGHT LED ", IPC F21V 29/00, publ. 03/10/2016).

Known LED lamp containing: a housing, a removable cover, under which are located: a diffuser, a board with LEDs and a power supply, a control unit (RF patent No. 105004 for a useful model "LED LAMP", IPC F21S 4/00, published 2011.05.27) ...

Known lighting device, consisting of a heat sink housing installed in it radiators, which are fixed LED elements, and a driver for powering LED elements (RF patent No. 137597 for a useful model "LIGHTING DEVICE ON LED BULBS", IPC F21S 13/00, publ. 20.02 .2014).

Known street LED lamp, consisting of a radiator housing, a light source in the form of a LED module, a power supply, mounting elements, protective glass (RF patent No. 125299 for a useful model "STREET LED LAMP", IPC F21S 13/10, publ. 27.02. 2013).

Known LED lamp containing a radiator housing, the first and second end caps, a fixing element for the lamp, a printed circuit board made of heat-conducting material, LEDs mounted on a printed circuit board, as well as a power supply unit with electrical wiring connected through a pressure seal to the printed circuit board, and a protective a screen made of optically transparent material (RF patent No. 154191 for a useful model "LED LIGHT", IPC F21S 8/00, publ. 08/20/2015).

The known luminaires do not provide for the possibility of replacing the driver during their operation without the need to dismantle the luminaire from the bearing surface, which is of great importance for industrial luminaires installed, in particular, in subway tunnels.

Known light-emitting diode lamp containing a radiator housing, a printed circuit board with LEDs, secondary optics of LEDs, a driver. The radiator case consists of two parts, one of which is made in the form of a radiator cover, in which the driver is installed, and the radiator cover together with the driver is made with the possibility of complete detachment from the radiator case. The radiator cover is located at the bottom of the radiator housing. The driver is fixed and sealed in the radiator cap by pouring the compound (RF patent №185549 for the utility model "LED LIGHTING", IPC F21S 13/00, publ. 03/28/2018).

The disadvantage of the known luminaire is the operational complexity of replacing the driver, since this entails replacing the radiator cap and installing a new cap with fixing and sealing the driver in it with a compound.

Known closest in terms of the set of essential features to the claimed utility model and selected as a prototype LED lamp containing a radiator housing, a printed circuit board with LEDs, a diffuser and a driver placed in a separate aluminum housing mounted on the radiator housing. The body is made in the form of a modular detachable structure connected by fasteners, while the upper part of the body is made in the form of vertically oriented ribs, and the body is also equipped with a fastening unit. The driver is equipped with a network cable connector with built-in screw terminals. (RF patent No. 147709 for a useful model "LED LAMP", IPC F21S 13/00, publ. 11.04.2014).

The implementation of the driver, located in a separate aluminum case, mounted on the radiator case, allows you to change it without removing the luminaire, which simplifies the maintenance of the latter. At the same time, installation of the driver (disconnecting the faulty driver from the luminaire body and installing a working driver on the luminaire body) requires a certain amount of labor, which, if a large number of luminaires need to be replaced, especially in places of increased strategic importance of the object, such as, for example, in subway tunnels can make a big difference.

The problem to be solved by the claimed technical solution is to create an LED lamp, characterized by improved performance characteristics.

The technical result achieved as a result of solving the problem is to simplify maintenance and improve the maintainability of the LED lamp by reducing the time to replace a failed driver.

The specified technical result is achieved by the fact that the LED lamp contains: a radiator housing, a printed circuit board with LEDs, a diffuser and a driver. The driver is housed in a separate aluminum casing mounted on a radiator casing. In this case, the driver housing contains grooves on the lower surface, and the radiator housing is equipped with guide rails rigidly fixed on its upper surface, the profile of which is made to match the grooves on the driver housing.

Preferably, the heatsink housing is made of anodized aluminum.

It is preferable that the diffuser has a trapezoidal shape, with an angle λ of inclination of the sides in the range of 45-60 degrees.

Preferably, the diffuser is made of non-combustible material.

It is preferable that the luminaire contains a built-in device for regulating the electric power of the luminous flux of the lamps (dimmer).

It is also preferred that the luminaire includes built-in remote control devices for the luminaire.

In some cases of execution, the guide rails can be fixed on the radiator casing by means of a detachable connection.

In some cases of execution, the guide rails can be fixed to the radiator casing by means of a permanent connection.

A comparative analysis of the claimed invention with the prototype showed that in all cases of execution, it differs from the known, closest technical solution:

- execution of the driver body containing grooves on the lower surface;

- the presence of guide runners;

- execution of guide rails rigidly fixed on the upper surface of the radiator housing;

- the execution of the profile of the guide rails, the mating grooves on the driver body.

In individual cases of execution, the utility model differs from the known, closest technical solution:

- execution of the case-radiator from anodized aluminum;

- implementation of a trapezoidal diffuser with an angle of inclination of the sides making up the range of 45-60 degrees.

- making the diffuser made of non-combustible material;

- the presence of a built-in device for regulating the electric power of the luminous flux of lamps (dimmer);

- the presence of a built-in device for remote control of the lamp;

- execution of guide rails fixed to the radiator casing by means of a detachable or one-piece connection.

Execution of the driver body containing grooves on the bottom surface, and the presence of guide rails rigidly fixed to the radiator body; the profile of which is made with mating grooves on the driver body, greatly simplifies the assembly of the luminaire and reduces the time spent on repairs, allowing you to quickly replace the power source without dismantling the entire luminaire, which greatly simplifies the maintenance of the luminaire and increases its maintainability.

The implementation of a trapezoidal diffuser with an angle λ of inclination of the sides, constituting a range of 45-60 degrees, practically eliminates the glare effect. The diffuser made of non-combustible material reduces the fire hazard of the product, and the presence of a built-in device for regulating the electrical power of the luminous flux of lamps (dimmer) and / or an integrated device for remote control of the lamp expands the functionality of the lamp.

The proposed utility model is illustrated by the schematic drawings of the LED lamp shown in FIG. 1-6.

FIG. 1 shows a schematic drawing of a LED lamp, general view.

FIG. 2 is a schematic drawing of an LED luminaire, front view.

In a preferred embodiment, the LED luminaire contains: a radiator housing 1 made of anodized aluminum, a printed circuit board 2 with LEDs 3, a diffuser 4 and a driver 5 located in a separate aluminum housing mounted on a radiator housing 1, and equipped with a network cable connector (on not shown in the drawing). In this case, the driver housing 5 contains grooves on the lower surface (not shown in the drawing), and the radiator housing 1 is equipped with guide rails 6 rigidly fixed on it, the profile of which is made with mating grooves on the driver housing 5. Diffuser 4 is made of non-combustible material (class PV 0), has a trapezoidal shape with an angle of inclination λ of the side, making up a range of 45-60 degrees, which provides uniform and soft illumination without a glare. It is preferable that the luminaire contains a built-in device for regulating the electric power of the luminous flux of lamps (dimmer) (not shown in the drawing) and built-in devices for remote control of the lamp (not shown in the drawing), which provide integration into intelligent lighting systems of industrial enterprises, in particular, the subway. The guide rails 6 are fixed to the radiator housing 1 by means of connection means (not shown in the drawing), which can be a detachable connection, for example, bolted, or one-piece, for example, a rivet.

The utility model works as follows.

An alternating electric current from the electrical network through the driver 5 enters the LEDs 3. The emitted luminous flux from LEDs 3 with an energy efficiency of at least 150 Lm / W, installed on aluminum printed circuit boards 2, is refracted through the diffuser 4 and directed outward. The aluminum body of the luminaire is a heat sink that removes heat from the LED boards. If the driver 5 fails, the case with the driver 5 is removed from the guide rails 6, instead of it, the case with a working driver 5 is installed along the indicated guide rails 6, and through the connection connector (not shown in the drawing) is connected to the network cable (not shown in the drawing ). The luminaire can be part of the "Smart Light" system, for this, various controllers, sensors, etc. are easily mounted in the luminaire, which allows you to control the luminaire remotely.
