1. The technical result is achieved by the fact that in an electric lighting system containing a solar battery, an electric energy accumulator, a charge controller, an inverter, a transformer, an electric line and lamps, the inverter is made in the form of a frequency converter, which is connected to a series resonant circuit, which consists of a capacitance and inductance of the primary winding of a resonant high-frequency boost transformer with an open core or without a core, high-potential high-voltage output the transformer winding is connected to a single-wire line, parallel to one of the terminals of n fixtures (n = 1, 2, 3, ..., n), each of the fixtures contains a lamp with two counter-parallel connected cathodoluminescent light sources with autocathodes, the second terminal each lamp is connected to a natural container in the form of an insulated conductive body, each lamp in the lamp is made in the form of a spherical sphere made of transparent glass, into which two electrode holders are inserted through soldered glass droplets c, the sphere is evacuated from the inside, divided by a solid wall into two hemispheres, coated with a phosphor layer from the inside, a thin layer of aluminum is applied over the phosphor to act as an anode, while the cathodes and aluminum coatings of the phosphors are connected to the electrode holders in such a way that each electrode is connected one autocathode of one hemispherical light source and one anode of another hemispherical light source, two hemispherical light sources connected counter-parallel, transverse they turn on and off when changing the polarity of the supply current, providing natural switching when the current passes through "zero", while the cathodes are made of nano-structured graphite and are located in the center of the lamp sphere, and the nano-tips of the cathodes are directed from the center of the hemisphere to the surface covered phosphor and a thin aluminum layer on top of the phosphor.

In the embodiment of the luminaire, an insulated conductive body representing a natural capacity is made in the form of metallized housings of cathodoluminescent lamps with autocathodes.

Figure 4 presents a picture of the energy states of the electron inside the material of the autocathode and the distribution of the electric potential in vacuum above the surface of the material of the autocathode when an external electric field is switched on, which reduces the work function of the electron from the autocathode due to the occurrence of a "tunneling" effect of the passage of electrons through the potential barrier. Figure 5 shows the design of a cathodoluminescent lamp containing two parallel-on-counter light sources with autocathodes based on a nano-structured carbon material used as an electron emitter in an autocathode.

The low-potential terminal 14 of the high-voltage winding 7 is connected through a capacitor 15 with the ground. The high-voltage winding 7 of the high-frequency resonant transformer 6 is connected by its high-voltage output 8 to a single-wire line 9 with luminaires 10-1, 10-2, 10-3, ..., 10-n (n = 1, 2, 3, ..., n) having natural capacities 11-1, 11-2, 11-3, ..., 11-n (n = 1, 2, 3, ..., n). Thanks to this, electric energy is supplied to the lamps and their work.

In Fig.2, electric energy from the solar battery 1 or from the battery 2 with the charge controller 3 is supplied to the input of the converter 4, then through the capacitors 12, 13 to the low-voltage winding 5 of the boost high-frequency resonant transformer 6. The low-potential terminal 14 of the high-voltage winding 7 is connected through a capacitor 15 with the ground. The high-voltage winding 7 of the high-frequency transformer 6 with its high-potential terminal 8 is connected to a single-wire line 9. Lamps 10-1, 10-2, 10-3, ..., 10-n (n = 1, 2, 3, ..., n) are connected by one terminal with a single-wire line 9. and another through current-limiting resistors 16-1, 16-2, 16-3, ..., 16-n (n = 1, 2, 3, ..., n) connected to the ground 17.

In Fig. 3, electric energy from the solar battery 1 or from the battery 2 with the charge controller 3 is supplied to the input of the converter 4, then through the capacitors 12, 13 to the low-voltage winding 5 of the boost high-frequency resonant transformer 6. The low-potential terminal 14 of the high-voltage winding 7 is connected through a capacitor 15 with the ground. The high-voltage winding 7 of the high-frequency transformer 6 is connected to the single-wire line 9 by its high-potential terminal 8. The single-wire line 9 generates a high-frequency electric field E. Electrically conductive bodies 18-1, 18-2, 18-3, ..., 18-n are in the electric field E ( n = 1, 2, 3, ..., n) forming electric capacitances with a single-wire line 9. The conductive bodies 18-1, 18-2, 18-3, ..., 18-n (n = 1, 2, 3, ..., n) are connected to the terminals of cathodoluminescent lamps 10-1, 10-2, 10-3, ... , 10-n (n = 1, 2, 3, ..., n), other terminals of the fixtures are connected to the ground 17.

Figure 4 shows the dependence of the potential energy of the electron, on the distance to the surface of the material of the cathode. The horizontal ordinate X shows the distance from the surface of the cathode in angstroms Å. The vertical ordinate represents the energy potential V _{e of the} electron in electron volts (eV). The vertical boundary 19 separates the material of the cathode and vacuum. The potential function of the electron φ _e over the surface of the material in the absence of an external field E is depicted by curve 20, it represents the work of diluting two different-polar electric charges equal to the electron charge e to the distance X. The potential function of the electron φ _E in the electric field E is depicted by curve 21 The total potential function φ of the electron above the surface of the material of the cathode in the presence of an external electric field E is shown by curve 22. To the left of the border 19 of the section "material of the cathode - vacuum" three energy levels are shown. The first level is the level of zero potential. It is equal to the potential of an electron removed from the material of the cathode to "infinity". The second level is the level of the bottom of the conduction band. He speaks of the width of the zone of allowed electron energies in the material of the autocathode involved in the acts of transfer of electricity in the material. The third level is the Fermi level (φ _f ). This is the average energy level from which the electrons “participating” in the process of emission from the material of the cathode to the vacuum start. The potential (the first is the energy of the electron that overcomes the potential barrier in the “above the barrier” mode. The width of the potential barrier, and at the level φ _f is the distance that the emitting electron travels when passing “under the barrier”, ie, in the “tunneling” mode, therefore, without performing the “work of exit.” The wave line conventionally shows the “tunneling” of the electron, and then the straight line to the right indicates the movement of a freely accelerating electron e by the field E in the direction of the conductive coating on the phosphor cathodoluminescent th light source.

Figure 5 shows the design of a cathodoluminescent lamp. It is a glass sphere 23, inside the sphere is covered with a layer of phosphor 24, 25, two hemispheres 26, 27 of a thin layer of aluminum are applied to the phosphor. Hemispherical aluminum coatings are connected to the metal leads 28, 29 soldered to the wall of the sphere 23. Auto terminals 30, 31 are also connected to the leads 28, 29. Thus, two light sources 32 and 33 are connected to the leads 28, 29 in parallel with each other in the opposite mode, due to this, the circuit supplying the lamp is equally loaded: one light source works in one half period, for example, 32, the second source works in the other half-cycle, respectively, in the case under consideration, 33. When the autocathode 30 or 31 turns out to be negative Tel'nykh potential with respect to the corresponding aluminum hemisphere 26 or 27, performing at the time the anode, the electrons in the "tuntselnogo" effect are emitted from the cathodes and typing kinetic energy equal to the electron charge on the potential of the anode fall to the aluminum coating of the phosphor. The thickness of the aluminum layer is such that the electron penetrates through it almost without loss of energy and hits the phosphor, where it loses its entire energy supply. The kinetic energy of the electron passes into the luminescent emission of photons with energy hν. Here ν is the frequency, h is the Planck constant, h = 6.62-10 ^-34 J. · sec. The frequency of the luminescent radiation ν depends on the phosphor material. If ν lies in the region of visible light, such a source can be used as a light source. Depending on the spectral composition, the light may be colored or white. The composition of the phosphor can be selected, giving light close in composition to the sun.

Thermally expanded graphite or carbon nanofibers are used as the active emission medium of the autocathode. A large number of stable emission centers are created on the surface of this material, made in the form of surface sections with very small radii of curvature.

The electric lighting system (Figure 1) works as follows. The electrical energy from direct current energy sources 1 or 2 is converted into alternating current energy in a frequency converter 4, increased in voltage using a high-frequency resonant transformer 6 and creates resonant current and voltage oscillations in the primary winding 5, the secondary winding 7 and in the single-wire line 9 with a frequency f ₀ = 1-100 kHz equal to the frequency of the alternating current at the output of the frequency converter 4.

Since the single-wire line 9 relative to the winding 7 is open, a phase shift of 90 degrees exists between the current and voltage in it. The current is 90 degrees ahead of the voltage and recharges the capacitance of a single-wire line 9, the capacities of the luminaires 10-1, 10-2, 10-3, ..., 10-n (n = 1, 2, 3, ..., n), and natural capacitances 11 -1, 11-2,11-3, ..., 11-n (n = 1, 2, 3, ..., n).

Electromagnetic energy in the form of a stream of current and voltage waves moves from terminal 8 with high potential along line 9 through luminaires 10-1, 10-2, 10-3, ..., 10-n (n = 1, 2, 3, ..., n ) to natural capacities 11-1, 11-2, 11-3, ..., 11-n (n = 1, 2, 3, ..., n) with a lower potential, which is the result of dividing the line potential with respect to:

C ₁₁ is the electrical capacitance of an insulated conductive body with respect to the earth, [Ф].

In another embodiment of the electric lighting system (Figure 2), electromagnetic energy in the form of a stream of current and voltage waves moves from terminal 8 with high potential along line 9 through luminaires 10-1, 10-2, 10-3, ..., 10-n ( n = 1, 2, 3, ..., n) to natural capacitances 11-1,11-2, 11-3, ..., 11-n (n = 1, 2, 3, ..., n), grounded through current-limiting resistors R. The potential of an isolated conductive body will be equal to

here: ω is the circular frequency of the current in the line [sec ^-1 ];

In another embodiment of the electric lighting system (FIG. 3), electromagnetic energy in the form of a stream of current and voltage waves travels from terminal 8 with high potential along line 9 through an electric capacitance between line 9 and insulated conductive bodies 11-1, 11-2, 11 -3, ..., 11-n (n = 1, 2, 3, ..., n) to the fixtures 10-1, 10-2, 10-3, ..., 10-n (n = 1, 2, 3, ... , n). The other end of the fixtures is grounded. In this embodiment, the potential φ _{11 of the} isolated conductive body is

here: C ₉ is the electric capacitance of an insulated conductive body with respect to a single-wire line 9, [Ф].

The operation of light sources based on a nano-structured carbon material as an emitter of electrons followed by their acceleration by the anode field, the collision of dispersed electrons with a phosphor and excitation of luminescent light is not accompanied by the energy consumption for electron emission, since the necessary conditions are created in the light source for “drawing” electrons from the emitter in the “tunnel” effect mode, i.e. the passage of electrons between the emitter and the vacuum “under the energy barrier”. The phosphor, depending on the composition, can emit blue, green, red or white light. For general-purpose lamps, the luminescence light can be chosen closest in spectrum to sunlight.

The density of the current emitted by the cathode can be described by the expression

where: A is the emission constant of the material of the emitter, [A / (m ² · deg ° K ² )];

T is the temperature of the emitter, [deg ° K];

e is the electron charge, e = 1.6 · 10 ^-19 , [K];

φ is the height of the potential barrier preventing the electron from leaving the material of the emitter, [eV];

k is the Boltzmann constant, k = 1.38 -10 ^-23 [J / deg ° K].

The height of the potential barrier is calculated according to the laws of quantum physics; in a first approximation, it is determined by the work that the electron emitted from the emitter must perform against the forces of electric attraction to the uncompensated positive charge arising in the material of the emitter. A graphic illustration of the above process is presented in FIG. 4.

Thermionic cathodes work by increasing the temperature T. This consumes a lot of energy. The field emission cathode operates by decreasing the height φ _o and the width of the potential barrier a

,

which is the maximum in the mathematical dependence of the work being done on the distance X by which the electron is removed.

Here: φ _f is the Fermi energy level for electrons in the material of the emitter, [eV];

E is the electric field strength at the surface of the emission center, [V / m];

ε ₀ is the dielectric constant of vacuum, ε ₀ = 8.85-10 ^-12 [F / m].

By increasing the electric field strength at the emitting surface, the height of the potential barrier can be reduced, while the width of the potential barrier a also decreases. When the width of the potential barrier a (Fig. 4) becomes comparable with half the wavelength of the electron wave function inside the emitter material, the effect of the passage of electrons through the potential barrier without energy overcoming it is observed, i.e. without the cost of supplying one's own energy, a tunnel effect. The wave function of an electron describes the probability density distribution of an electron at a point in space of interest, and its square is the probability of detecting an electron at that point.

An increase in the electric field at the emitting surface can be obtained by increasing the voltage at the anode (metallized surface of the phosphor) or by reducing the radius of the emission surface:

Here: k is the coefficient of proportionality, [V · m];

R is the radius of curvature of the emitting surface, [m].

Structurally (Figure 5), the lamp is a spherical sphere 23 made of transparent glass with electrode holders 28, 29 inserted into it through glass sealed through drops and located inside the sphere. One of the emitters 30 is attached to one of the electrodes 29 to ensure electrical contact electrons. The emitter 30 is used to generate free electrons in one light source 32. Another electrode 28 is connected to the metal coating of the phosphor - the anode 26. On the other of the electrodes 28 is also attached to provide electrical contact electron emitter 31. The emitter 31 serves to generate free electrons in another light source 33. The metal coating 27 of the phosphor 25 serves as the anode in the light source 33.

Thus, an electron emitter 31 is connected to the electrode 28 - the source autocathode light 33 and the metal coating 26 of the phosphor 24 is the anode of the light source 32, which provides a counter-parallel inclusion of light sources in the lamp.

An example of a device for an electric lighting system.

A solar battery 1 (Fig. 1) with a power of 300 W and a voltage of 12 V and a secondary battery 2 with a voltage of 12 V are included for operation with a frequency converter 4 of 25 kHz and a power of 150 W with an output voltage of 12 V. A boost high-frequency resonant transformer 6 contains 8 turns of a low-voltage winding 5 and 2500 turns of the high-voltage winding 7, while a potential with a voltage of 10 kV at a frequency of 25 kHz is generated at the high-voltage terminal 8. Each of the luminaires 10-1, 10-2, ..., 10-n contains a lamp (Figure 5) with two counter-parallel connected cathodoluminescent light sources 32 and 33 with auto-cathodes. White lamp with an operating voltage of 10 kV at a frequency of 25 kHz, with a luminous flux of about 1200 lm and an operating current of 5 mA.

Due to the consumption of electrical energy in the resonant mode and the use of cathodoluminescence as a light-emitting mechanism, the generation of a cathode electron beam using an energy-efficient charge transfer mechanism - as a result of the passage of electrons through a potential barrier on the surface of the emitter, as well as the transfer of energy to the lamp via a single-wire line with low losses in the conductor, the operation of the electric lighting system is carried out with high efficiency equal to 80-90%. When the luminaire is powered via a single-wire line, the possibility of a short circuit is excluded, since there are no conductors with a potential difference between them, as is the case in a conventional electrical network. As a source of electrical energy can be used not only a solar battery, but also any other source of electrical energy.
