Air light performance system

Technical Field

The invention belongs to the technical field of photoelectricity, and particularly relates to an air lamplight performance system.

Background

The existing air light performance (light show) is usually completed by hundreds of unmanned aerial vehicles with LED point light sources, even more than thousands of unmanned aerial vehicles, each unmanned aerial vehicle emits light to form a pixel point after flying to the sky, hundreds of unmanned aerial vehicles and thousands of unmanned aerial vehicles can generate hundreds of pixel points in the night sky, and the constantly changing pixel points form a dynamic light picture scroll, so that the unmanned aerial vehicles are popular and unforgettable. The defects that a picture is formed by using an unmanned aerial vehicle light source as a luminous pixel point to perform light performance are as follows: 1. the displayed picture has low pixels, usually only dozens to hundreds of pixels, and 1374 pixel points generated by 1374 unmanned aerial vehicle performances are world records at present; 2. because the unmanned aerial vehicles participating in the performance cannot be too close to each other, otherwise the unmanned aerial vehicles are easily interfered and even collided, the light pixel interval is large, and therefore exquisite images cannot be displayed in the air; 3. because of low pixels and large pixel spacing, the unmanned aerial vehicle light show can only be viewed from far and cannot be viewed from near (when the unmanned aerial vehicle light shows the image, that is, the unmanned aerial vehicle light show can only be performed from far, which causes that the light intensity is seriously attenuated, the brightness of the light image seen by the audience is low, even is similar to starlight, and the light image effect is greatly reduced; 4. hundreds of unmanned aerial vehicles and thousands of unmanned aerial vehicles are synchronously controlled in real time, so that the unmanned aerial vehicles accurately fly to corresponding pixel positions in a design image according to instructions, the technical difficulty is very high, and errors are easy to occur; 5. hundreds of unmanned aerial vehicles and thousands of unmanned aerial vehicles which perform light shows can only perform light show shows in the night sky for about 5 minutes, cannot meet the watching demands of people, and people often do not have to see addiction and finish the shows; 6. because the number of unmanned aerial vehicles used for performing is huge, the unmanned aerial vehicles usually have hundreds of unmanned aerial vehicles, even thousands of unmanned aerial vehicles, and the needed auxiliary maintenance personnel and resources in all aspects are numerous, the cost of performance at each time is huge, so that the light show of the unmanned aerial vehicles is difficult to see, and most of citizens in cities cannot enjoy the feast of the light show of the unmanned aerial vehicles; 7. because the number of unmanned aerial vehicles performing light shows is huge, the risk of failure or accident is high, for example, 1374 unmanned aerial vehicles performing light shows in the city of western security of China in 5 and 1 months in 2018 fall uncontrollably at last, so that for the sake of safety, the unmanned aerial vehicles can perform only over open places (such as squares, river surfaces and lake surfaces), and no people can be below the performance airspace; 8. the performance can only be carried out in the air in a distant and spacious place, and the audience can only see low-light images after the brightness of the light is attenuated, so the performance cannot be synchronously carried out as the background of a ground stage.

Disclosure of Invention

The invention aims to overcome the defects of low picture pixel, great flight control technical difficulty, short empty performance time, high cost, limited performance occasions, poor lighting effect and the like in the existing unmanned aerial vehicle lighting performance, and provides the air lighting performance system with exquisite picture, easy control, long performance time, high safety and low cost.

The technical scheme adopted by the invention for realizing the purpose is as follows: an air light show system comprises an unmanned aerial vehicle and a light string group; the unmanned aerial vehicle is a multi-rotor unmanned aerial vehicle, a ducted unmanned aerial vehicle or an unmanned helicopter, and the weight of the whole unmanned aerial vehicle is more than 5 kg; the lamp string group is formed by hanging at least 2 lamp strings on a hanging rod (cross rod) or a hanging ring, wherein each lamp string is formed by more than 4 light-emitting units and electric wires connected with the light-emitting units, and the whole lamp string group is hung below the unmanned aerial vehicle; the light-emitting units are light sources such as LED pixel lamps (LED point light sources), LED guardrail tubes (LED contour lamps and LED digital tubes) or lanterns, and each light-emitting unit is provided with an IC (microcontroller) and can emit light with different colors and intensities under the control of the controller; the wires connecting the light-emitting units are 4 wires, wherein 2 wires are used for transmitting electric energy for the light-emitting units, and the other 2 wires are used for transmitting control signals; in addition, the unmanned aerial vehicle or the lamp string group is also provided with a controller for controlling the light-emitting units on the lamp strings to emit light according to the program setting, and the controller is in circuit connection with the light-emitting units through electric wires; the lamp string group works from a power supply with a battery or carried by the unmanned aerial vehicle, or the whole system is connected with a ground power supply through an electric wire (cable) to get electricity. When the unmanned aerial vehicle is used, the unmanned aerial vehicle hangs the lamp string group to fly into the air, each light-emitting unit on the lamp string in the lamp string group emits light under the control of the controller, each light-emitting point is a pixel, and the pixels generated by all the light-emitting points form a dynamic magic color, character, pattern or video to be displayed in the air, so that various light image change effects such as flowing water, chasing light, scanning, pattern, writing, fireworks and the like can be displayed.

In the air light performance system, the light string group of which the light string is hung on the suspender (cross bar) can show a plane light image in the air; the lamp string group is hung on the hanging ring by the lamp string, and can show a cylindrical light image in the air; after the unmanned aerial vehicle with the lamp string group rotates rapidly, light images in the forms of concentric circles, cones, drums and the like can be generated in the air. If a plurality of sets of air light show systems are used simultaneously to perform light shows, various plane and three-dimensional light image effects can be generated in a combined mode.

In the air light show system, the batteries for supplying power to the light strings and the controller can be carried by the unmanned aerial vehicle and also can be independently arranged on the hanging rods or hanging rings of the light string group. In addition, the electric energy of the whole system can be supplied by a power supply (power grid) on the ground or in a building through an electric wire, so that the unmanned aerial vehicle can hang the lamp string group to work in the air for a long time and perform light shows in the air for a long time.

In the air light show system, the controller for controlling the work (light emission) of each light emitting unit can be carried by the unmanned aerial vehicle, can also be arranged on the lamp string group (for example, hung on a suspender or a hanging ring of the lamp string group), or is arranged on the ground, and transmits a control signal to each light emitting unit through an electric wire when in use.

In the air light performance system, the bottom ends of the light strings on the light string group are usually connected with a bottom rod or a bottom ring, so that the light strings do not drift with wind even if wind exists during the air light performance, the relative stability of the positions of the light emitting units in the light string group is ensured, and the stability of light images is ensured without generating a disordered image.

In the air light show system, the unmanned aerial vehicle or/and the light string group are generally connected with a safety rope, and the length of the safety rope is greater than the height of the light string group. When the air light show system is used for air light show above or beside a building (such as a high building and a television tower), the lower end of the safety rope is tied on a fixed object (such as a water pipe at the top of the high building) at the upper part of the building. If unmanned aerial vehicle breaks down at the performance in-process and leads to the air crash to take place, this safety rope just can hold unmanned aerial vehicle and lamp cluster group, and unmanned aerial vehicle and lamp cluster group just can not drop ground and injure the people by a crashing object like this.

In the air light performance system of the invention, besides the electric wire connected with the light-emitting unit, each light string is also provided with a stressed wire (such as nylon rope, steel wire and the like) which is connected with each light-emitting unit and the suspender or the suspension loop (the upper end of the stressed wire is connected with the suspender or the suspension loop). The function of this atress line is to bear the weight of each luminescence unit and electric wire to and the centrifugal force that the lamp cluster produced after the lamp cluster group rotated along with unmanned aerial vehicle.

In the air light show system, the lamp string group can be connected with the upper hook according to the use requirement. By utilizing the hook, the lamp string group can be hung on the top of a high-rise or a cable in the air. After the lamp string group is hung on the top of a high-rise building or a cable in the air, light shows can be stably carried out in the air for a long time without being hung by an unmanned aerial vehicle all the time.

In practical application, the air light performance system can be used for carrying out air light performance by hanging a set of light string group by one unmanned aerial vehicle, and can also be used for carrying out air light performance by hanging a plurality of sets of light string groups by a plurality of unmanned aerial vehicles; when the air light performance is carried out, the device can be suspended in the air for performance, and can also be used for performance in a flying or lifting state. When the air light performance system is used for light performance, a small amount of existing light performance unmanned aerial vehicles can be added to perform together, so that a wider air stage effect is achieved.

The air light performance system has the advantages that: because the number of the light-emitting units in the light string group hung below the unmanned aerial vehicle is dozens of, more than hundreds of, even thousands of, and the distance between every two adjacent light-emitting units can be as small as zero (the adjacent light-emitting units are close to each other), a huge image with higher resolution and more exquisite can be displayed in the air, and even smokeless, environment-friendly, low-cost and flamboyant electronic firework performance can be performed in the air; because the unmanned aerial vehicle used for light performance only has one, several or dozens of unmanned aerial vehicles, the unmanned aerial vehicle is much less than hundreds of unmanned aerial vehicles and thousands of unmanned aerial vehicles used for light performance, the unmanned aerial vehicle is easier to control in the light performance process, and the safety is higher; because the relative position of each light-emitting unit in the light string group is basically fixed and cannot change due to external interference, the relative position of a pixel point formed after light emission is basically fixed, and the phenomenon of image disorder caused by error of a positioning signal in the existing unmanned aerial vehicle light performance can be avoided; because the unmanned aerial vehicle with the whole weight more than 5kg and even the load more than 100kg is used for hanging the lamp string group for air light performance, the energy of the carried battery is larger, the air performance time is longer, if the ground or high-rise power supply is used for supplying power, the air light performance in the whole night is not in place, compared with the existing unmanned aerial vehicle light performance which is usually less than 10 minutes, the unmanned aerial vehicle light performance is a huge technical breakthrough and progress; because a large-capacity battery or a ground power supply can be used, the lighting device can carry a light-emitting element with higher power to perform light shows, and brighter and more beautiful light pictures are displayed; because the number of the unmanned aerial vehicles used for performing the light show is small (usually, only one, several or more than ten), the required maintenance personnel is also small, and the show cost is much lower than that of the existing unmanned aerial vehicle light show; the air light performance system has the advantages that safety is guaranteed by the safety rope, and the air light performance system cannot fall to the ground even if a fault occurs when performing above the roof of a high-rise building, so that light performance can be performed above the high-rise building with dense buildings in a city, and the air light performance system can be hung on the high-rise building or a cable for performing, so that the occasion suitable for air light performance is greatly expanded, and more people can enjoy banquet of the air light performance; the air light performance system can be hung on a high-rise building or a cable to perform light performance at a short distance, or the ground is used for supplying power to perform light performance, so that audiences can see brighter light pictures, and the air light performance system can also be used as a background of a ground stage to perform synchronously with the ground stage.
