Abstract

FIELD: electricity.

SUBSTANCE: light-emitting diode lamp contains globoid divided in circumferential direction into parts, light-emitting diodes installed at light-reflective surface and communicating with in-built power supply unit and screw base through conductors. At that each part with screw base has elements of electric contact, which contact each other when parts are joined into whole globoid. For the purpose of joining into globoid each part has screw thread.

EFFECT: diversification of LED lamps and simplification of their assembly procedure.

Description

The invention relates to the field of lighting and for the construction of LEDs intended for use in industrial and domestic lighting, in 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 the LED lamp containing a spherical body, on the reflective surface, the LEDs communicating through conductors with an integrated power supply and a screw base, the spherical body is cut in a circle at least into two parts having built-in electrical contact elements with conductors attached to them. The spherical body is configured to connect / disconnect parts. LEDs are located on the surface of a spherical body in round holes.

Figure 1 shows the LED lamp with a spherical body consisting of two parts, figure 2 and 3 depict, respectively, LED lamps with a spherical body consisting of two and three parts (LEDs on the surface of the spherical body are indicated by sections).

Examples of LED lamps.

The LED lamp (figure 1) contains a spherical body 1 made of plastic with a reflective (mirrored) surface 2, having round holes 3 with LEDs 4 located at their centers, an integrated power supply 5, a screw base 6. The holes can be shallow or deep, have the same or different diameters. The spherical body is cut in a circle into two parts 7 (with a base) and 8, each of which has built-in electric contact elements 9 with conductors 10 connected (soldered) to them, electrically connecting the LEDs with an integrated power supply and a screw base. Each part of the spherical body contains LEDs that emit one light, such as white. Parts of the spherical body can be glued, welded to obtain an integral connection.

The LED lamp (Fig. 2) differs from the one discussed above in that the spherical body is cut in a circle into two oblique parts: part 11 with a base and part 12. The parts contain LEDs that emit different light, for example, LEDs are placed on one part of the spherical body emitting red light, on the other part - LEDs emitting blue light. Parts are replaceable. At least in one part of the spherical body, a channel 13 may be formed for connecting / disconnecting the parts by the fastening elements 14. Between the parts can be installed flat annular gasket 15, for example, of rubber.

In the LED lamp (figure 3), the spherical body consists of three parts, respectively, 16, 17 and 18, of which one (central) has a screw base. Parts may have screw threads 19 for possible (multiple) connection / disconnection thereof. Each part of the spherical body has LEDs that emit the same or different light, for example red, yellow, green.

The manufacture of the LED lamp (figure 1) provides for the production of part 7 with an integrated power supply 5 and a screw (E 27, E 14) cap 6 and part 8. The manufactured parts are connected into a single spherical body 1 by gluing or welding. In this case, the elements 9 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 enters through the conductors 10 to the LEDs 4 located in the holes 3 of the reflective surface 2. The LED lamp emits white light. When the lamp fails, it is replaced (disposed of).

The manufacture of the LED lamp (figure 2) provides for the manufacture of part 11 with a screw base and part 12. The manufactured parts are connected by installing a gasket 15 in a spherical body using fastening elements 14 using channels 13. The gasket prevents moisture, aggressive gases from entering the spherical body . When the LED lamp is connected to the mains, light emission of red and blue color occurs. If any part fails, this part is replaced, extending the lamp life.

The manufacture of the LED lamp (Fig. 3) provides for the production of part 17 with an integrated power supply and a base and parts 16 and 18. The parts are connected using screw thread 19. When the LED lamp is connected to the mains, light emission, for example, red, yellow, green . If any part fails, it is replaced, for example, with the same new one. Failed lamp parts are disposed of.

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