Implementation of the utility model

Previously, in gas-discharge lamps, a housing or a housing plus an ignition unit (ECG) was considered a lamp, the lamp and ECG were consumables and the repair of the lamp was not difficult. With the advent of LED luminaires, the luminaire itself has become a complex technical product, with low maintainability, which excludes repairs by ordinary consumers.

The proposed modular LED luminaire provides versatility, easy replacement of the board with LEDs and lenses (thereby adjusting the illumination from the luminaire), the layout of a wide range of powers within the majority of existing and projected luminaires.

This solution allows you to increase the service life of the lamps, their maintainability, since there is no need to send the lamps to the manufacturer for repair, as a result, the costs of repair and improvement of lamps are significantly reduced, since you can easily replace boards with LEDs with more efficient ones or replace power supplies without any impact on the lamp.

Figure 1 shows a luminaire known from the prior art, however, its body has a significant thickness due to the high body height, it does not provide for easy replacement of the luminaire modules.

To create the proposed model of a modular LED luminaire, a modular design is used in the form of a radiator (cast or pressed by extrusion of an aluminum profile) with technological recesses for attaching a transparent plate with lenses, a hole for fastening and a power cable outlet. Figure 2 shows an exemplary view of the radiator, but the figure does not show the hole for the connector for the electrical cable.

This design provides stable and normal heat transfer between the LED board and the heatsink, which ensures a temperature of 60-65 degrees Celsius with an LED power of about 25 watts.

The housing of the modular luminaire is made detachable to the lighting unit and can be made of either metal or plastic. This modularity and the ability to quickly replace any luminaire module provides greater freedom in luminaire manufacturing.

Figure 3 shows an assembled lighting unit. Attached to the radiator 301 is a translucent plate 302, in the recess of which is a board 303 with LEDs 304. The fastening in this embodiment is made with screws 305. Power is supplied via an electrical cable 306.

Easy replacement of modules can be carried out due to the availability of screw connections, the point of contact of the translucent plate 302 with the board 303, as well as the minimum air gap between them allow for additional heat dissipation.

Assembly and operation of the proposed device

The assembly is carried out as follows: a board with LEDs is installed on the radiator, a translucent plate is installed on top, which is attached to the radiator in a removable manner, for example, with screws, fastening the plate simultaneously leads to pressing the board with LEDs, which is pre-installed in the recess of the translucent plate, to the radiator. Thermal grease can be used to improve thermal contact between the board and the heatsink.

In order for the luminaire modules to be positioned correctly relative to each other, their sizes and means of functional connection with each other are selected accordingly.

The dimensions of the recess in the translucent plate and the dimensions of the board with LEDs correspond to each other so as to ensure that the board with LEDs is pressed against the heatsink, as well as to ensure that the lens of the translucent plate is located in such a place and at such a distance relative to the LEDs to provide a given luminous flux. The recess in the translucent plate can contain protrusions for pressing the board, the recess itself can have different levels of depth such as to press the board only along the edges. A person skilled in the art, without creative effort, will be able to offer many options for implementing the proposed mounting of the translucent plate and the board to the housing.

The fastening of all elements to each other is carried out using screws, bolts, clamps or other means of quick detachable connection.

The number of LEDs on the board can be any, preferably it ranges from 1 to 100, even more preferably from 4 to 40, even more preferably from 6 to 20. The optimal number of LEDs is selected for ease of modification on one side (so as not to change the translucent plate to each individual LED if necessary) and maintaining the flexibility of modification (the more individual modules can be modified, the more combinations of lighting parameters can be realized).

The assembled lighting unit can be attached to the body by means of detachable connections, the elements of which (holes, threads, slots, hooks, clamps) are provided on the radiator.

After connecting the power supply to the board with LEDs through the connector provided for this, installed in the radiator, the LEDs begin to emit light and the modular luminaire starts to work.
