Description

The invention relates to the field of lighting and for the design of LED lamps for lighting public and residential premises.

Known LED lamp containing a spherical body, placed on a reflective surface of the LEDs communicating through conductors with a built-in power supply and a screw base [1]. Such a lamp can be connected to AC 220 V.

The objective of the invention is to expand the range of LED lamps, simplifying the technology of their assembly.

The technical result is achieved by the fact that in an LED lamp containing a spherical body, LEDs placed on a reflective surface communicating through conductors with an integrated power supply and a screw base, the spherical body is made in the form of a regular / semi-regular polyhedron, consisting of two parts, with a surface in the form concave regular polygons with LEDs located in their centers. The spherical body has the shape of a dodecahedron. The spherical body has the shape of an icosahedron. The spherical body has the shape of a semi-regular polyhedron with a surface consisting of regular pentagons and hexagons. The spherical body is configured to connect / disconnect parts, and the line of their connection / disconnection runs along the edges of the polygons. One of the parts of the spherical body is equipped with a permanent magnet, and the other with a ferromagnetic plate.

Figure 1 shows a General view of the LED lamp with a spherical body, having the form of a semi-regular polyhedron with a surface consisting of regular pentagons and hexagons; Figures 2 and 3 show general views of LED lamps with a spherical body having the shape of a regular polyhedron, respectively, of a dodecahedron and an icosahedron, Fig. 4 shows a diagram of the supply of electricity to the LEDs.

Examples of LED lamps.

1. The LED lamp (figure 1) contains a spherical body 1 made of plastic, made in the form of a semi-regular polyhedron with a reflective (mirrored) surface 2 in the form of concave regular polygons (in this case, pentagons and hexagons) 3 with LEDs located in their centers 4. The spherical body is divided into two parts (halves) 5 and 6 with the possibility of their connection along the broken line A, passing along the edges of 7 polygons. Each part of the spherical body contains LEDs that emit the same light, such as white. One of the parts has a built-in power supply unit 8 and a screw base 9. Moreover, each part of the spherical body has built-in elements of electrical contact 10 with conductors 11 connected (soldered) to them, electrically connecting the LEDs with the built-in power supply and a screw base. Parts of the spherical body can be glued, welded to obtain an integral connection.

2. The LED lamp (figure 2) differs from the one considered above in that it has a spherical body in the form of a regular polyhedron - a dodecahedron with a reflective surface consisting of regular concave polygons (in this case, pentagons) with LEDs located at their centers. Parts contain LEDs that emit different light, for example, LEDs emitting red light are placed on one part of the spherical body, and LEDs emitting green light on the other part. Parts of the spherical body are made with the possibility of their detachable connection, for example, due to the built-in permanent magnet 12 in one part, and ferromagnetic plates 14 in the other part.

3. The LED lamp (figure 3) differs from the above in that it has a spherical body in the form of a regular polyhedron - an icosahedron with a reflective surface, consisting of regular concave triangles with LEDs located in their centers. Parts of a spherical body can have both one-piece and one-piece connection. Each part of the spherical body can have LEDs that emit the same or different in color light.

The manufacture of the LED lamp (Fig. 1) provides for the manufacture of part 6 with an integrated power supply unit 8 and a screw (E 27, E 14) base 9 and part 5. The manufactured parts are connected along line A into a single spherical body 1 by gluing or welding. In this case, the elements 10 of the electrical contact of each part come into contact. When the LED lamp is connected to the mains, electricity is supplied through the base to the built-in power supply, from where it goes through the conductors 11 to the LEDs 4 located in the centers of the concave polygons 3 on the reflective surface 2. The LED lamp emits white light. When the lamp fails, it is replaced (disposed of).

The manufacture of LED lamps (figure 2 and 3) does not fundamentally differ from the above. The fabricated parts of the spherical body are connected by means of permanent magnets 12 integrated in one part and ferromagnetic plates 14 in the other part. Such a connection allows for the replacement of parts. If any part fails, this part is replaced, extending the lamp life. For example, a part of a lamp with LEDs emitting green light can be replaced with the same part of a lamp with LEDs emitting blue light. Failed lamp parts are disposed of.

This technical solution expands the range of LED lamps, simplifies the technology of their assembly. Having a set of interchangeable parts, you can vary the power, color radiation, lamp life.
