Multiple LED light 210 in two LED frameworks, and two LED frameworks are separately positioned, the ferris wheel branch
Frame 100 is located between two LED frameworks.It is preferred that each LED light is respectively arranged at described in two regularly arrangedly
In LED framework and two separately positioned LED displays are integrally formed;It is possible thereby to realize the LED screen formula ferris wheel
Double-sided display effect, the large space for making full use of ferris wheel to provide shows that time or display efficiency can be understood as increasing
One times is added, can accordingly promote this respect sells about one times of the time of display.Preferably, two LED frameworks are symmetrical
Setting, i.e., it is symmetrical relative to skyscraping wheel support or in which heart face.It is preferred that each LED light is set respectively regularly arrangedly
It is placed in two LED frameworks, separately positioned and symmetrical two LED displays are integrally formed in each LED light.By
Simplified control mode may be implemented in this, and a set of control system can control two LED displays;Also, symmetrical two LED
The light emission direction of the LED light of display screen is reversed, it is possible thereby to realize that two LED displays can individually be shown, is not interfere with each other.
It is preferred that two LED frameworks are symmetrical arranged, the fixed frame of each LED frame is fixed on the ferris wheel
It on the fixed part of bracket and is also used to be directly fixed on the ground, the rotating bezel is fixed on the rotating part of the skyscraping wheel support
On point, each LED light is set to regularly arrangedly on the rotating bezel;It is possible thereby to realize the symmetrical LED framework of structure,
Convenient for simplifying production and installation, and ventilative area is higher, and enhancing LED screen formula skyscraping is additionally aided under the premise of thermal diffusivity is good
The wind resistance of wheel which thereby enhances the stability and applicability of LED screen formula ferris wheel, for example, will treated picture number
According to being shown on LED display curtain structure, since ferris wheel and LED framework are two-sided, data are being launched it is possible thereby to realize
When, verso images do mirror image processing, to guarantee that observer can always see static image.Alternatively, two LED frameworks
The fixed frame be symmetrical arranged, and the rotating bezel of two LED frameworks is staggered, so that two rotations
Each asymmetric setting of LED light on frame is also referred to as staggered, i.e., the LED light at rotating bezel is located at mutually another rotation
The ventilation port position of frame, it is possible thereby to realize that the position of the symmetrical fixed frame of structure and LED light interlocks, in this case due to
Wind area increases and wind loading rating is caused to decline, but heat dissipation performance is more preferable, and small-sized ferris wheel is more suitble to use.
It is preferred that the skyscraping wheel support has round or regular polygon profile.One embodiment as shown in fig. 7,
LED screen formula ferris wheel includes skyscraping wheel support 100 and multiple cockpits 110 for being fixed on the skyscraping wheel support;It is worth referring to
It out, is the profile simplified shown in Fig. 7, for showing that the LED screen formula ferris wheel is that in a manner of setting and have and turn
The wheeled devices of dynamic state.Preferably, as shown in figure 8, the LED framework 220, which is provided with regularly arranged become, is parallel to ground
Linear frame body with each LED light of fixation.It is preferred that one LED module of each linear upper setting of linear frame body, i.e., linear
Frame body it is each it is linear on each LED light as one group of LED module.Or, it is preferred that as shown in figure 9, the LED framework 220
The regularly arranged linear frame body as perpendicular to ground is provided with each LED light of fixation.It is preferred that same as above, line
One LED module of each linear upper setting of shape frame body, i.e., linear frame body it is each it is linear on each LED light as one group of LED mould
Group;Certainly, here be parallel to ground or perpendicular to ground be it is opposite, change with the rotation of LED screen formula ferris wheel.
That is, the LED screen formula ferris wheel is with multiple lateral LED modules as shown in Figure 8 positioned at circular inner zone or such as
Multiple longitudinal LED modules shown in Fig. 9, transverse and longitudinal here be it is opposite, change with the rotation of LED screen formula ferris wheel.
Or, it is preferred that as shown in Figure 10, the LED framework is provided with regularly arranged frame body in length and breadth with each LED lamp of fixation,
It is preferred that the LED screen formula ferris wheel, which has, is located at for example round or regular polygon interior zone the lattice of skyscraping wheel support
Palisade LED module, grid-like LED module are equipped with a large amount of LED light;Preferably, as shown in figure 11, frame body is equipped with rule in length and breadth
The LED light of arrangement, certainly, in practical applications, the quantity and density of the LED light in the LED screen formula ferris wheel are much larger than
The quantity and density of LED light shown in Figure 11;When whole LED light in the LED screen formula ferris wheel shine, such as Figure 12 institute
Show, LED framework is almost not visible for a user at this time, it is possible thereby to realize the effective of video image or picture character
