Description

The utility model relates to lighting engineering, namely to LED lamps and can be used as a lighting fixture in office retail, sports, industrial and other premises.

Known modular LED lamp (patent for utility model No. 106333, IPC F21S 8/00, published July 10, 2011), containing a diffuser and a metal base on which the LED bars are evenly distributed and fixed.

The disadvantages of this technical solution include low lighting rates due to the presence of only one power supply, because in case of failure, the lamp does not fully work.

Known LED ceiling light (patent for utility model No. 87598, IPC H05K 5/00, H01L 33/00, published 10.10.2009), containing a housing with a window made of translucent material (diffuser), evenly distributed and mounted on the rear wall enclosures LED rulers, hole for wires, power supply unit, made inside the enclosure.

The disadvantages of this technical solution include low lighting rates due to the presence of only one power supply, because in case of failure, the lamp does not fully work.

Also known is the "LED Ceiling Light" (patent No. 132524, IPC F21S 8/04, published September 20, 2013). In the LED ceiling lamp, consisting of a housing with a diffuser, evenly distributed and fixed on the rear wall of the housing of the LED rulers, holes for wires, a power supply unit made inside the housing. The diffuser is fixed in the groove formed by the bend of the side wall of the housing and an additional corner made inside the housing. The number of LED lines is even. The power supply is located in the center of the case, parallel to the rulers, and the hole is made opposite the terminals of the power supply and is equipped with a pressure seal.

This technical solution for its functional purpose and for its technical nature is the closest to the claimed one and is taken as a prototype.

Known LED lights have reduced lighting (performance), due to the presence of only one power supply. This approach to the principle of connecting light sources does not allow the luminaire to remain functional; when the “bundle” fails, the power supply is a light source.

The technical result, the achievement of which the claimed utility model is aimed, is to increase the efficiency of the lamp.

The technical result is achieved by the fact that in the LED ceiling lamp, consisting of a housing with a diffuser, evenly distributed and fixed on the rear wall of the housing of the LED rulers, a hole for wires, equipped with a hermetic lead, of at least one power supply unit made inside the housing, the diffuser is fixed in the bend groove the side wall of the housing, made inside the housing. The side walls of the body are L-shaped. Two parallel side walls of the housing are made with a bend of a U-shape for placement of a diffuser in it. A U-shaped bend is placed in the upper part of the side wall parallel to the rear wall of the housing. The housing is equipped with additional elements in the form of U-shaped plugs placed at the ends of the housing perpendicular to the side walls, made with a bend. Each LED line is equipped with a power supply, which are placed along one of the side walls of the L-shaped without bending and without violating the uniform distribution of mechanical loads, while the input circuit (220 V) from all power supplies are connected in parallel. From the lamp comes one supply wire for all power supplies.

In addition, the diffuser is made integral, and the luminaire housing is additionally equipped with a double U-shaped insert mounted perpendicular to the side walls of the housing, made with a bend, along the axial line to accommodate the components of the diffuser.

In the claimed LED lamp, the common essential features for this solution and for its prototype are:

- housing;

- a diffuser, which is fixed in the groove of the bend of the side wall of the housing, made inside the housing;

LED strips evenly distributed and fixed on the rear wall of the housing;

- hole for wires equipped with a pressure seal;

- at least one power supply located inside the housing.

A comparative analysis of the claimed LED lamp and prototype shows that the first, in contrast to the second, has the following distinctive essential features:

- the walls of the housing are L-shaped;

- two parallel side walls of the housing are made with a bend of a U-shaped shape for placement of a diffuser in it;

- A U-shaped bend is placed in the upper part of the side wall parallel to the rear wall of the housing;

- the housing is equipped with additional elements in the form of plugs of a U-shape, placed at the ends of the housing perpendicular to the side walls made with a bend;

- each LED line is equipped with a power supply, which are placed along one of the side walls of the L-shaped without bending and without violating the uniform distribution of mechanical loads;

- input circuits (220 V) from all power supplies are connected in parallel.

Based on the foregoing, we can conclude that the set of essential features of the claimed utility model has a causal relationship with the achieved technical result - improving the lamp performance.

The utility model is illustrated by drawings, where in FIG. 1 shows a General view of the lamp; in FIG. 2 - layout of elements (without plugs); in FIG. 3 - section along the side wall 4; in FIG. 4 - a U-shaped plug and FIG. 5 - insert a double U-shaped.

The LED ceiling light consists of a translucent diffuser 1, the rear wall 2 of the housing, side walls 3 and 4, LED strips 5 mounted on the rear wall 2 of the housing, openings 6 with a pressure seal 7, power supplies 8, a bend 9 of a U-shape, plugs 10 U-shaped, insert 11 double U-shaped, supply wire 12. The diffuser 1 is made integral. The side walls 3 and 4 of the body are L-shaped. Two parallel side walls 4 of the body are made with a bend 9 of a U-shape to accommodate the components of the diffuser 1. A U-shape bend 9 is placed in the upper part of the side wall 4 parallel to the rear wall 2 of the body. The housing is equipped with two additional elements in the form of plugs 10 of a U-shape placed at the ends of the housing perpendicular to the side walls 4 made with a bend 9. The housing of the lamp is additionally equipped with a double U-shaped insert 11 mounted perpendicular to the side walls 4 of the body made with a bend 9 along the center line. Each LED line 5 is equipped with a power supply 8.

Power units 8 are placed along one of the lateral walls of the 3 L-shaped without bending and without violating the uniform distribution of mechanical loads. Input circuits (220 V) from all power supply units 8 are connected in parallel.

The assembly process of the lamp is as follows. LED bars 5 are attached to the rear wall 2 of the housing. Power supply units 8 are placed along one of the side walls 3. The power wires of the rulers and 220 V are connected. The power wire 12 is pushed through the hole 6 with the pressure lead 7 to the outside of the lamp. In the groove of the U-shaped bend 9 of the side walls 4, an insert 11 of a double U-shaped is installed. From 2 opposite sides of the side walls 4, diffusers 1 are installed by pushing into the U-shaped bend 9 of the side walls 4 until they are fixed in the grooves of the double U-shaped insert 11. On the side walls 3, plugs 10 are U-shaped (fixed by fasteners) .

The presence of several LED lines, each connected to its own individual power supply, allows the lamp to remain operational; if any of the “bundles” fails, the power supply is a light source. Each LED line is wired to its power source through a quick-release connector mounted on the line.

Thus, in the proposed technical solution, the task of increasing the lamp performance by supplying each LED line with a power supply, as well as two additional elements in the form of U-shaped plugs placed at the ends of the housing perpendicular to the side walls, is solved.
