Description

The invention relates to the field of lighting and for the design of LED lamps for special purposes and the cartridge for it.

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 socket [1]. Such a lamp can be installed in a cartridge and connected to an alternating current network of 220 V. For example, a cartridge is known which comprises a detachable housing with an opening for mounting the base of the LED lamp and an opening for cable entry, two electrical contacts [2].

The objective of the invention is to expand the assortment of LED lamps and lampholders for them, increasing the service life and the ability to replace lamp parts.

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 base, the spherical body consists of two parts made in the form of hemispheres that can be disconnected, each part having basement. Parts of the spherical body have a screw connection. Parts of the spherical body have magnetic connections and are equipped with studs that prevent their displacement.

For the functioning of the claimed LED lamp, a cartridge is proposed that contains a detachable housing with an opening for mounting the base of the LED lamp and an opening for cable entry, electrical contacts, has two adjacent holes for installing the sockets of one LED lamp and an additional electrical contact with the possibility of its adjunction to the housings of each base. The cartridge case is equipped with fixing elements with a base.

Figure 1 shows a LED lamp with a spherical body consisting of two parts having a screw connection and round socles round in cross section installed in a lampholder (LEDs on the surface of the spherical body are indicated by sections); figure 2 shows a light-emitting diode lamp with a spherical body consisting of two parts having a magnetic connection and square socles in cross section; figure 3 presents a General view of the cartridge for the LED lamp depicted in figure 2.

The LED lamp (Fig. 1) contains a spherical body 1 made of plastic, consisting of two separate parts 2 and 3, made in the form of hemispheres: The parts of the spherical body have a screw connection in the form of a short screw 4 located in its center with a thread on one part and through hole 5 with a mating thread on the other side. Each part of the spherical body has a round base 6 in cross section, consisting of a smooth body 7 with a central electrical contact 8. On the reflective surface 9 of each part of the spherical body there are LEDs 10 connected by conductors 11 to the integrated power supply unit 12 and the base. Parts of the spherical body contain LEDs that emit the same color, for example white. Parts are replaceable. The lamp base of the LED in cross section can be in the form of a circle, ellipse, square, rectangle, polygon, for example an octahedron.

The LED lamp (Fig. 2) differs from the one described above in that it has square socles and a magnetic connection of the parts of the spherical body in the form of a permanent magnet 13 located in its center on one part and a ferromagnetic plate 14 on the other part. Parts of the spherical body contain LEDs that emit different light; for example, on one part there are LEDs emitting red light, on the other part there are LEDs emitting blue light. In each part of the spherical body non-through opposing channels 15 with studs 16 installed in them can be made.

The sockets of each part of the spherical body are installed in the cartridge (figures 1 and 3), consisting of a detachable housing 17 with two adjacent holes 18 (for mounting the sockets) and a hole 19 for inputting a three-core cable 20. Two electrical contacts 21 are attached to the housing, adjacent to the central electrical contacts of the socles, and an additional electrical contact 22 adjacent to the housings of each socle. The housing may be provided with elements 23 for fixing the plinths made, for example, in the form of short plastic screws.

The manufacture of the LED lamp (Fig. 1) provides for the manufacture of parts 2 and 3 with LEDs 10 on the reflective surface 9, connected by conductors 11 with integrated power supplies 12 and round in cross section socles 6 having a smooth body 7 and a central contact 8. The manufactured parts are connected into a single spherical body 1 by turning and screwing a short screw 4 with a thread on one part into a non-through channel 5 with a mating thread on the other part to the position when one base is located against the other.

A cartridge is made (Fig. 1) with a detachable housing 17, round adjacent holes 18, an opening 19 for inputting a three-core cable 20. Electrical contacts 21 and an additional electrical contact 22 are fixed in the housing.

The lamp base of the LED lamp is installed (inserted) in adjacent holes of the cartridge housing, fixing their position by the elements 23. When the LED lamp is connected to the mains, the following options for its operation are possible: light emission only by the LEDs located on part 2; light emission only by LEDs located on part 3; light emission by LEDs located on parts 2 and 3. The LED lamp emits white light. When any part fails, it is replaced, extending the overall lamp life. The failed part of the lamp is disposed of.

The manufacture of an LED lamp (Fig. 2) differs from the manufacture of the above-described lamp in that its parts have square bases in the cross section and the magnetic connection of the parts of the spherical body with the help of centrally located permanent magnet 13 on one part and on the other part of the ferromagnetic plate 14 . The displacement of the parts is prevented by the studs 16 installed in the channels 15.

A cartridge is made (FIG. 3). In adjacent square holes set the lamp base LED (figure 2). When the lamp is connected to the mains, LEDs emitting red light, or LEDs emitting blue light, or all LEDs located on the reflective surface of a spherical body can be turned on. When any part fails, it is replaced, extending the overall lamp life. If you have a set of parts with LEDs that emit light of different colors, you can vary the layout of the lamp. The failed part of the lamp is disposed of. The cartridge is used repeatedly.

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.
