Description

The present invention relates to devices for lighting. It can be used for lighting streets, squares, water spaces and other open areas. It will find application in lighting places during emergencies by rescue services or police services, if there is an urgent need to establish checkpoints, illuminate the place of investigation. It can also be used for outdoor recreation, for an emergency stop of the car at night on the road and for car repairs. In addition, the lighting installation can be used for advertising purposes, because allows you to attach a variety of promotional materials to its inflatable part and attract the attention of consumers.

Lighting installations are known that contain a base, a transparent flexible airtight shell fixed on the base with an air intake hole, equipped with an air injection source and a light source fixed in the inner cavity of the support (incandescent lamp, LED light sources). Invention patents RU 2192581, RU 2286510, utility model patents RU 47486, RU 57870, RU 57871, RU 187954.

The disadvantages of the known technical solutions include the impossibility of using them without using a generator or a car battery as a power source, which is often required in emergency situations when it is necessary to illuminate open areas, in places that are difficult to get to. In addition, the disadvantages include large overall dimensions and weight, due to the presence of a generator in the configuration of lighting installations (PM RU 47486, RU 57870, RU 57871). The need to quickly carry a light installation often arises in emergency services, for example, when eliminating a traffic accident, when a car with victims was carried far beyond the roadway, where it is impossible for special equipment to drive up, while every minute is needed to save people. Rescue workers are forced to manually deliver to the emergency site the equipment necessary for emergency assistance to victims, in such cases the size and weight of the light installation is of great importance.

Also, the lack of known devices can be called the inability to add a light source to those already installed, the absence of a rigid top cover, without which the flexible shell of the lighting installation during operation in emergency situations can be damaged during transportation. The absence of legs - stops, necessary in those conditions when it is not possible to install anti-wind extensions (asphalt, paving slabs). The absence of a special storage place for connecting wires, stakes and anti-wind extensions, which leads to the frequent loss of inventory necessary for the deployment of a lighting installation.

Closest to the claimed technical solution is a utility model according to patent No. 187954, which is accepted by the applicant as a prototype.

The objective of the present invention is to create an ergonomic lighting installation that can be connected both from various external power sources and from a power source located inside it and allows the use of the lighting installation in places remote from roads and in any hard-to-reach terrain.

The technical result of the invention is to increase the reliability, autonomy and ease of use of the light installation.

The technical result is achieved due to the fact that in a light installation containing a base with a cover on which a flexible support is fixed, made of a flexible airtight transparent shell, a light source on LEDs, a source of air injection into the shell, power supplies, starting equipment, a connector for connecting 220V power supply, a connector for connecting a 12V power source located at the base, according to the invention, the lighting installation contains a battery pack, and the 220V power supply connector is connected to a light source on LEDs and an air injection source through a power supply unit that converts the mains voltage 220V AC current into direct rectified current 12V, moreover, the power supply unit with which the 220V power supply connector is connected, as well as the 12V power supply connector and the battery pack are connected to the starting equipment through the power distribution device.

The battery pack is a battery connected to the connection control relay and the battery connection control module and is made using LiFePo or LiPo technology.

The power distribution device is made in the form of a terminal block.

A voltage cutoff device is placed between the 220V power supply connector and the 12V power supply connector.

The starting equipment is located on the upper horizontal surface of the base and is made in the form of a push-button control station, the buttons of which are made of three-position.

The cover is made rigid and provided with fasteners for wires, and the base contains folding support elements;

The light source is configured to increase the number of LEDs.

Supplying the lighting installation with a battery pack, which is a high-capacity battery made using LiFePo or LiPo technology, connected to the connection control relay and the battery connection control module, allows you to turn on the lighting installation where there is no access to the mains, generator or car battery. Due to the use of LiFePo or LiPo batteries, it is possible to provide the required battery life of the lighting installation. The battery connection control module charges the battery when it is connected to a 220V power source. In addition, the battery connection management module powers the lighting system when it is disconnected from external power sources. This increases the autonomy of the lighting installation, as well as the convenience of its operation.

The implementation of the trigger equipment on the upper horizontal surface of the base under a rigid cover protects the light installation from accidental switching on, protects the launch equipment from external influences during transportation, makes it easy to transport the lighting installation to the site without fear of damaging the flexible support, which is essential for emergency services, that is, it increases the reliability of the lighting installation and the convenience of its operation.

The implementation of the starting equipment in the form of three-position buttons allows you to change the luminous flux (power of the LEDs) of the lighting installation. During operation, it is possible to switch the starting equipment to the desired position at a given time. In this case, the starting equipment of the light source is connected to the light source through a step-up module and is connected to the power control unit. The power control unit is made in the form of a complex of fixed and variable resistors. That is, when switching the starting equipment of the light source to the appropriate position, the brightness of the LEDs changes.

Providing the base of the lighting installation with folding support elements prevents the installation from falling in an open area in strong winds, when it is not possible to install anti-wind extensions, which increases ease of operation, and also plays an important role in ensuring the autonomy of the lighting installation.

To change the power consumption and extend the operation of the unit from the built-in battery, as well as to expand the operational properties of the unit, it provides the ability to change the number of LEDs. This will allow the light unit to be used in various conditions, and will also allow you to change the battery life of the light unit by reducing or increasing the number of LEDs. LEDs with a main power cable are connected using special terminals. Each LED is connected to the main power cable separately from the other, this allows you to add or remove an LED module to solve a particular problem. In addition, such a constructive solution makes it possible to carry out repairs “on the spot”, if the end user has spare parts. At the same time, in case of failure of one of the LED modules, the second one will continue to work, since they are independent of each other.

The claimed combination of features ensures the achievement of a technical result, which consists in increasing the reliability, autonomy and ease of use of the light installation.

As a result of the patent research, no similar solutions known from the prior art, characterized by the claimed set of features, have been identified, which allows us to conclude that the criterion "novelty" and "inventive step" are met, the lighting installation also meets the criterion "industrial applicability" since it can be manufactured on an industrial scale using standard equipment.

The essence of the proposed technical solution is illustrated by drawings, where:

figure 1 shows a General view of the light installation;

figure 2 shows a top view without a cover;

figure 3 shows a side view without a cover;

figure 4 - block diagram of the light installation.

The light installation contains a base 1 with a cover. On the base 1, a flexible support 2 is fixed, made of a flexible airtight transparent shell. Also, the base 1 contains a light source 3 on LEDs, a source 4 of air injection into the shell, starting equipment 5 of the light source, starting equipment 6 of the air injection source, connector 7 for connecting a 220V power supply, connector 8 for connecting a 12V power source. The 220V power supply connector 7 is connected to a light source 3 on LEDs and an air injection source 4 through a power supply unit that converts the mains voltage of 220 Volts 50 Hz AC into a direct rectified current of 12 Volts 9. The base 1 contains an additional battery pack 10, which is a battery 11 connected to the connection control relay 12 and the battery connection control module 13 . The battery pack 10 is connected to a 220 volt power supply via a charger. The battery connection control module 13 is made in the form of a charging-balancing device and contains a charger made in the form of a 12-volt power supply and a BMS board. The battery 11 is made using LiFePo or LiPo technology.

The connector 7 for connecting a 220V power supply, the connector 8 for connecting a 12V power source and the battery pack 10 are connected to the starting equipment 6 of the air blower and to the starting equipment 5 of the light source through the power distribution device 14. The power distribution device 14 is in the form of a terminal block. Between connector 7 for connecting a 220V power supply and connector 8 for connecting a 12V power source, a voltage cutoff device 15 is placed.

The light source 3 is connected to the light source trigger 5 via a step-up module 16 and is connected to a power control unit (not shown). The power control unit is made in the form of a complex of fixed and variable resistors.

The starting equipment 6 of the air blower is connected to the source 4 of forcing air into the shell through the device 17 for controlling the speed of the air blower.

The starting equipment 5 of the light source and the starting equipment 6 of the air blower are located on the upper horizontal surface of the base 1. The cover is made rigid and provided with fasteners for wires. The base 1 contains collapsible support elements 18. The light source 3 is configured to increase the number of LEDs. LEDs with a main power cable are connected using special terminals. Each LED is connected to the main power cable separately from the other.

Light installation is used as follows.

Preliminarily, the light installation is installed on a flat area (any - earthen, gravel, grass). Further, with the help of the starting equipment 6 of the air injection source, power is supplied from the power source through the power supply unit, which converts the mains voltage of 220 Volts 50 Hz AC into a direct rectified current of 12 Volts 9 to the source 4 of air injection into the shell, which in the initial position is in the folded state, as the pressure inside the shell increases, it expands completely, becomes stable and firm, and occupies a vertical position. Then, using the starting equipment 5 of the light source, the light source 3 on LEDs is turned on from the power supply, while air from the environment enters the flexible support 2. Inside the flexible support 2, a fabric membrane is made, on which the light source 3 is installed inside the flexible support 2 and thus most protect the light source 3 from environmental influences and all kinds of precipitation.

Consider the operation of the lighting installation for the case when the vehicle's on-board electrical system is used as a power source: in this case, connector 8 is used to connect a 12V power source. Using the starting equipment 6 of the air injection source, power is supplied from a 12V power supply through the power distribution device 14 to the air injection source 4 into the shell, as the pressure inside the flexible support 2 increases, it straightens out, becomes stable and firm, takes a vertical position, then when with the help of the starting equipment 5 of the light source, the light source 3 is turned on, while the light source 3 is mounted on the fabric membrane.

Let's consider the operation of the lighting installation for the case when the built-in rechargeable battery is used as a power source: in this case, the lighting installation must be installed on a flat area (for example, asphalt, gravel, earth, as in any other cases). Using the starting 6 equipment of the air injection source, power is supplied from the built-in battery 11 through the battery connection control module 13 and the power distribution device 14 to the air injection source 4 into the shell, which is in the initial position in the folded state. As the pressure inside the flexible support 2 increases, it expands completely, becomes stable and firm, and occupies a vertical position. Then, using the starting 5 equipment of the light source, turn on the light source 3 on LEDs from the power supply, while the air from the environment enters the flexible support (preferably through a filter, which prevents dust and dirt from entering the flexible support), inside the flexible support 2 is made a fabric membrane on which the light source 3 is installed inside the flexible support and thereby protect the light source 3 from environmental influences and all kinds of precipitation.
