As the show is on material thickness and containing the lighting device 14 with an electric lamp 16, the control unit 18, which is designed to supply electricity to the lamp 16 and pneumatic energy to fill the shell 12 of the balloon 10. The sheath material 12 can comprise, for example, plasticized or not plasticized fabric or simply plastic film.

The shell 12 has an approximately elliptical shape, wherein the upper inner part is covered with a reflective film. The base shell 12 has an opening provided with a mounting flange 20 connected with the mounting means with the support plate 22 of the control unit 18. The base plate 22 are provided with mounting stand 24, the exhaust down and equipped with holding means 23 with ball bearings made with the possibility of the occurrence of the fixation in the tubular mast or support 25, fulfilling the role of a support for the balloon 10. Inverted U-shaped bracket 26 mounted on the inner surface of the base plate 22 to impart mechanical rigidity to support the lighting device 14.

The bracket 26 is covered with a bell-shaped insulating casing 28 forming the dielectric and heat shield between the lighting device 14 and the control unit 18. Between the bracket 26 and the top of the casing 28 raspolagetsya directly on the upper surface of the casing 28 and the outer side of the internal space of the latter.

The lighting device 14 includes an insulating intermediate sleeve 32 made in particular of polytetrafluoroethylene and supported on the casing 28 and serves as a support for the cartridge 34 to install the lamp 16. The intermediate sleeve 3 has an internal bore for the passage of electrical wires 36 between the Chuck 34 and the control unit 18. Electric lamp 16 may be an incandescent lamp or halogen lamp, formed by an elongated tube with a double shell, and with electric power, equal to 1000 watts.

The lamp 16 is installed in the Central zone of the balloon 10 and runs along the minor vertical axis of the balloon 10, while it is coaxially surrounded by a cylindrical protective grating 38, preventing contact of the shell 12 with the lamp 16. The grid 38 is formed by a set of rigid metal rods 40, made for example from stainless steel and are located at equal angular distance along the forming line of the cylinder. The rods 40 are curved at the top for the education of the armature 42 in the form of a spherical bowl, bonded to the Central plate 44 located on the minor axis in the direction of the lamp 16.

Made of stainless steel with whom rhna part of the casing 12. Individual metal rods 40 grid 38 are connected to each other by means of cylindrical spacers 50, arranged coaxially with respect to the supporting stand 24 and distributed at equal intervals along the minor axis.

The control unit 18 within the casing 28 provided with a pneumatic blower device 52, such as a suction device or an electric fan with blades or turbine intended for the filling of the shell 12. Pneumatic blower device 52 includes an inlet opening 54 passing through the support plate 22 to suction air and the outlet 56 for directing air under pressure into the shell 12 through the holes in the casing 28.

The fan is driven very low-voltage motor, for example, with a voltage of 12V or 24V, which supplies the electronic circuit 58 connected through a step-down transformer to the mains supply cable 59. The pressure sensor 60 is installed on the wall of the casing 28 and communicates with the electronic circuit 58 to turn off the power supply to the lamp 16 when the pressure of the air inside the shell 12 is below a specified threshold.

Assembly and airbag lights work the research Institute, when the shell 12 is fully lowered and placed in a box together with lighting device 14 and the control unit 18.

Filling and lighting the balloon 10 is controlled by applying voltage to the electronic circuit 58, which first actuates pneumatic blower device 52 for the automatic filling of the shell 12. As soon as the pressure inside the shell 12 is sufficient, it is possible to apply the voltage to the lamp 16 for illumination of the balloon 10.

The shell 12 is not completely impermeable to air due to the presence of small outlet openings, for example, at the level of the joints 62 two semi-elliptical portions along the major axis of the shell 12.

Fan electropneumatic device 52 egcogi damage to the shell 12, due to accidental or intentional puncture.

Integration of the control unit 18 in the casing 12 simplifies security measures to protect people from insulation defects, as the balloon is located on the mast at a certain height above the ground. The user is not in direct contact with the control unit and the lamp 16 when the plug of the power supply is connected to the socket outlet.

The elliptical shape of the shell 12 when full allows you to increase the illumination area, and the mechanical rigidity of the shell along the minor axis is particularly effective for the stability of the balloon relative to the wind.

In addition to the pressure sensor 60, the control unit 18 can be controlled by an adjustable svetozashitnogo relay (not shown) for automatic switching on and off of the balloon 10.

In addition to an electrical outlet, which is the main source of electricity, the electronic circuit 58 may be connected to the reserve source of energy, such as battery pack or battery installed on the base plate 22 inside the casing 28. In the case of disconnection of the AC power source when the circuit breaker protective circuit-who the state. From an alternate source current depends on the capacity of a backup power source and can be increased by reducing the intensity of the illumination lamp 16 to the level of emergency lighting during the intermediate phase.

The availability of an alternate source makes the balloon 10 is fully Autonomous, and support it fully charged with the charger, which can be also integrated into the casing 28.
