Description

The invention relates to lighting devices, mainly to signaling devices of lighthouse devices and railway traffic lights.

Known lighting devices that contain:

- the ceiling and at least one reflector located inside it with holes made in them, while at least one of the holes of the reflector is equipped with a pipe brought out through the hole in the ceiling outside the latter, and the pipe is attached to the ceiling and serves as a support for the reflector [ one];

- a sequentially installed light source, a light guide with a side reflective surface and a capacitor in which the output highlander of the light guide is optically coupled to the plane of installation of the illuminated object, and the light source and the input end of the light guide are mounted with the possibility of moving in space relative to each other, and the side surface of the light guide is made the side surface of the polyhedron, and the light guide itself is mounted to rotate around its axis [2];

- a housing with a light source and capacitors inside it mounted in a frame [3];

- a round-symmetric reflector, consisting of microstructural elements bordering each other along the meridial and equatorial chords of the core and having equal full angles of radiation in the meridial and equatorial planes and macrostructural reflectors made in the form of spherical cells whose geometric centers of curvature are located on the normal to the surface of the core [ four];

- a source with a pulsation frequency of 100 Hz and a modulator with two holes installed along its beam, in which, in order to maintain the level of light fluxes, the angle between the holes is selected from the condition & = 0.06 P (where P is the speed of rotation of the modulator, rpm) while for the drum modulator n = 3000 rpm [5];

- a flask with an incandescent body placed in it, the terminals of which are connected to the electrodes for supplying two converters of electrical energy to sound [6];

- a flask of optically transparent material filled with a gas mixture, a filament body sealed inside it on the conductors, and an element designed to mix the gas mixture, and the filament is installed along the axis of the element [7];

- a casing with a front opaque panel in which the light source and filters are placed, mounting plates installed in the casing and interconnected by pins and holes made in the corresponding mounting plates, in which are made recesses for mounting the filter flanges and the holes aligned thereto, at the same time, light filters are installed in the holes of one of the mounting plates, and light sources are placed in the holes of another [8];

- a flask hermetically installed in it on the electrodes of the filament body, made in the form of a spiral of refractory metal wire and a cap [9].

The main disadvantage of the known devices is that the heating and cooling of the filament body depends on its thickness. With prolonged burning of the lamp, its filament constantly evaporates and becomes thinner. With a decrease in the diameter of the thread, its resistance increases, which is accompanied by a decrease in current strength, temperature and light flux, which reduces the range of visibility of the fire, and also limits the service life and increases energy consumption during operation. In addition, to ensure the necessary color of fire, it is necessary to use filter filters.

These shortcomings were partially eliminated in a device containing a radiation source isolated from the external environment by a transparent shell connected to the housing, and contacts in which flat semiconductor crystals are located around the circumference, which allows to increase reliability, increase the operating period and reduce inertia [10]. This device (prototype) compares favorably with its analogues [1-9], however, it does not fully satisfy the requirement of the International Convention for the Safety of Navigation with regard to ensuring "high intensity for the night vision of the observer" especially in adverse weather conditions.

The objective of this proposal is to increase the radiation intensity and expand the range of application of the device.

The problem is achieved due to the fact that in the incandescent device of the signal light apparatus containing a radiation source isolated from the external environment by a transparent shell connected to the housing, contacts, a pin on which semiconductor crystals are the radiation source, the transparent shell has a lid on top , the housing has holes for supplying flexible wires to the contacts, in which the pin is made in the form of a printed circuit board, and the semiconductor crystals are grouped into an LED modules located on mutually perpendicular coordinate axes at nine levels, with three LED modules at the first and ninth levels, six LED modules at the second and ninth levels, six LED modules at the second level, at the third, fourth and on the sixth level there are eight LED modules, on the fifth level there are nine LED modules, on the seventh level there are seven LED modules, and on the eighth level there are six LEDs x modules, respectively, at fixed distances from the transparent shell and at certain angles to the optical axis, which provide crossing light fluxes from the LED modules formed in predetermined directions, and the transparent shell is made in the form of an arc providing light transmission of the emitted light in the frequency range from 460 to 633 newmen.

The implementation of the pin in the form of a printed circuit board with the placement of semiconductor crystals in the form of modules on mutually perpendicular axes at eight levels in a specific order, with a transparent shell in the form of an arc, provides light transmission of the emitted light with the required intensity.

This combination of new features from the prior art has not been identified, which allows us to conclude that the claimed invention meets the patentability condition "inventive step".

The invention is illustrated in the drawing, where the positions indicated are the housing 1, the printed circuit board 2, the LED modules 3, the transparent sheath 4, the contacts 5, the cover 6, the openings for the supply of flexible wires 7.

The housing 1 is made of a polymer material. The cover 6 is made of brass and, in addition to its intended use, also serves as a heat sink from the conductors through which electric current is supplied.

The printed circuit board 2 is made of getenaksa, on which the contacts are located 5. The transparent shell 4 is made in the form of an arc of a transparent polymeric material, such as macrolon, with protection from ultraviolet radiation. LED modules 3 are placed on circuit board 2 in the following order - three LED modules are located on the first level, six on the second, eight on the third, eight on the fourth, nine on the fifth, eight on the sixth, seven on the seventh six on the eighth, three on the ninth.

The transparent sheath 4, the printed circuit board 2, the LED modules 3, the contacts 5 and the cover 6 are fixed in the housing using an adhesive-forming substance.

Semiconductor crystals grouped into diode modules 3 are a source of coherent radiation and provide direct conversion of electrical energy into light. As semiconductor crystals, uniaxial crystals are used, which are optically anisotropic and do not have birefringence. The emitted light is determined by the parameters of the crystals. Circuit board 2 provides an unambiguous correspondence to a certain combination of signals at the inputs and certain combinations of signals at the outputs, which allows you to overlap the frequency ranges:

for red 610-633 nm; for yellow 538-590 nm; for green 505-535 nm; for orange 590-610 nm; for blue 460-490 nm,

The device operates as follows. The voltage from the power source through flexible conductors passing through the holes 7 in the housing 1 and connected to the contacts 5 is supplied to the board 6, where signals are generated that are fed to the radiation source 3, which converts electrical energy into light. The arrangement of the LED modules in a certain order provides an angle of visibility in the horizontal plane of 270 degrees, in the vertical plane of ± 7.5 degrees from the optical axis. The elevated temperature on the transparent shell 4 made of macrolon does not exceed 65 degrees Celsius. At the same time, the visibility range is at least 3 miles.

The proposed device compares favorably with analogues and prototype. With a relatively simple design and manufacturability, its use eliminates such a disadvantage of known analogues as inertia, and thus increases the light transmission, which allows the basic requirement for signal light devices to ensure high intensity for night vision of the observer to be fulfilled, and also allows to expand the range of radiated frequencies, which ensures the use of the claimed device as a signaling device in the operation of almost all Vehicle.

The implementation of the claimed invention on the existing elemental base does not present technical difficulties, which allows us to conclude that the proposed proposal meets the patentability condition “industrial applicability”.
