As everyone knows, stroboscopic effect is that McGraw-Hill Dictionaryof Scientific and Technical Terms (is seen, 2 in the basis of film and TV ^NdEd., McGraw-Hill Book Company, New York, etc., 1978, p.1553).

For film, this effect is to realize by moving as the cinefilm of image information carrier in the light source front, and its speed film picture (frame) that each is independent with persistence of vision time (≈ 0.1s) of surpassing the people is shown on the screen continuously.So, on screen, just can see static and dynamic image.With the same reason of a series of films of demonstration, on the screen of television equipment and computing machine, formed image.

Yet preprepared film and the TV that is used for advertisement can only attract some professionals usually in exhibition, trade fair, because common visitor has been accustomed to these a long time ago.

For showing commercial unit and material, this mode is very satisfactory, still, clearly, arrives shop and Food Outlets for a large amount of crowds of attraction, and shows that in exhibition or trade fair this mode of commodity of public demand can not be satisfactory.

Equally, have only by using fashionable animate program, advertising message can be adjusted on computer screen relatively soon, and the film of standard, TV are just repeating during whole exhibition of promoting the sale of goods monotonously.

Here it is, and why advertising circle acknowledged expert K.BOVE and W.ARENS (see Contemporary Advertising, 5 ^ThEd., Richard D.Irwin, Inc., 1994) emphasize: up to the present the needs of shared routing are very urgent, and this shared routing can be adjusted the advertisement that is used to show frequent variations at an easy rate.

The array display apparatus or the multi-screen television presentation assembly of the programming of " portable cord (traveling line) " type that use is widely known by the people do not reach gratifying effect.Usually, the basis of this equipment is a big and heavy framed structure, and the individual light source that is mounted to (or many) line of hundred (to thousands of) is equipped with in its front.These light sources provide power by the opertaing device of a high complexity, such as well-known United States Patent (USP) 4967373.Particularly, this equipment is intended to control the array demonstration assembly of a polychrome, comprising:

A converter links to each other with described image data control circuit, is used for becoming electric signal to control described projection assembly described image transitions.

As everyone knows, array display device can be transmitted news and advertising message for the city public effectively.Yet for those mobile crowds, same advertisement seems, and effect is very little, is attracted to usually on the commodity and service of the public demand that is provided by little company if wish notice with client, and the cost of this transmission information is too expensive.Why Here it is presses for a kind of cheapness, simple, reliable display device.In the middle of these devices that can address that need by its technical characterictic, immediate is that it comprises according to the display device of United States Patent (USP) 4689604:

The cylinder of a ring-type is as the carrier of light source;

A power rotating driver links to each other by an axle with described carrier;

Three light source post groups are installed in the outside of rolling drum surface as showing cylinder, and each group light source comprises a plurality of light sources;

A light source control unit, it comprises a microprocessor; A position transducer that is used to provide carrier positions; A synchronizer that is used for synchronous light source operation; A software is used for receiving and image data processing, and becomes order to cut out light source this data-switching.

In running, advertising message strides across rollers roll to rotate opposite direction with cylinder.Whole information is made up of a plurality of frames, and the span that every frame covers is not more than cylinder periphery, and comprises an initial light source cylinder and a not end light source cylinder that separates.Position transducer starts microprocessor and generates a series of synchronizing signals all consistent in each display column, so in the rotary course of each cylinder, control module is each light sources setting operation sequence, and the operation of each display column synchronously.

In this device, because the intuitive of advertising image is embodied directly on the apparent cylinder background, therefore, the validity of advertisement is owing to show that for a long time visitor and shopper get used to the illumination image on any carrier and reduced in fact.So, when people during with service, if there are not specific purposes, can not note those advertisements at the commodity of seeking public demand usually.

(Fig. 1 and Fig. 2 left part) in the ordinary course of things, a carrier 4 that is supported on 23 of the rotating drivers is consistent with the shape of a corresponding rotary body generatrix, the sectional dimension of its thickness and light source 5 matches, and the width that the thickness of carrier 4 and footpath make progress makes carrier 4 disappear from spectators' sight line on illusion when axle 3 rotations; The Surface Vertical (Fig. 2) of the rotary body generatrix that the optical axis of each light source 5 and carrier 4 limit on the carrier 4.In order to demonstrate the stereo-picture of many spherical objects, light source 5 must be installed to the position of carrier 4, intersect near the center of the geometrical line that makes light source 5 and the given object of institute, will be no more than 5% with the crossing error of fleet angle measurement.

Suggestion is in the geometric surface of carrier 4, and is particularly shown in Figure 3 as Fig. 1,2, and oppositely balance stem 8 should support on the axle 3 of rotating driver 2.This balance stem is the arbitrary shape with balance carrier 4, balance stem preferably one have its outside the assistant carrier (Fig. 1, Fig. 2) of light source 5 be installed.As can be seen from Figure 3, balance stem 8 may be consistent with the shape of its rotary body generatrix, and is identical or different with main carrier 4; And the axis of balance stem 8 distance axis 3 has bigger space than carrier 4.In addition, the carrier 4 or the thickness (m) of balance stem 8 that light source 5 arranged are (Fig. 3) by expression formula d _Pls＜m≤9d _PlsSelect, wherein, d _PlsBe the thickness of section of the light emission surface of pointolite; The width B of carrier 4 (Fig. 2) should be by expression formula B＜=0.1R _MaxSelect, wherein, R _MaxBe at utmost away from the radius of a circle (Fig. 2) that limits by light source 5 of axle 3 axis.

Below be the theoretic example of rotary body generatrix:

Straight line is used for cylinder or cone;

Circular arc is used for spheroid;

Different arcs, preferably smooth arc, for example ellipse, hyperbola, para-curve etc. are used for corresponding ellipsoid, hyperboloid, parabola etc.

The combination in any of straight line and/or identical arc and/or different arc.

The special case that is used for the possible rotary body generatrix of main carrier 4 shows at Fig. 4,6,8, and shown the carrier 4 that light source 5 all is housed and the small number of combinations of balance stem 8 in Figure 10 and 12.Fig. 5,7,9,11 and 13 has shown the corresponding rotary body of this combination.Certainly, very clear, these examples do not limit the quantity of possible rotary body generatrix, and the press agent can according to circumstances select other possible rotary body generatrix arbitrarily.

In simple embodiment of the present invention, have corresponding Fig. 1 and 2 and Figure 10 and 11 two parts (about) specific variant.From Fig. 1 and 2, particularly find out among Figure 10, the light source 5410110 of carrier 4 one best is about 180 ° greater than 90 ° angle, yet balance stem 8 has covered a common scope at 10 ° to 40 ° angle.When on balance stem 8 light source 5 being installed, they preferably are installed in the middle part corresponding to the light source 5 of main carrier 4.

More complicated variant according to device of the present invention also is possible.In the variation of Figure 14, there is a carrier at least, rise over against the inside surface of the rotation of axle 3 light source 5 is housed; A main carrier 4 is only arranged or only have a balance stem 8 or the two all to have this unimportant.Carrier 4 and balance stem 8 do not have the restriction of quantity, can directly or by the support that light source is not housed support on each output shaft 3.Preferably all detachable at any time convenient repairing of these parts and replacing.Among some embodiment, the above-mentioned support that light source is not housed (not specifying) as the part of balance stem 8 shown in Fig. 1,2,10,12.

In geometrical plane (Figure 18 and 19), being angle Φ with respect to main carrier 4, to have at least an assistant carrier 4 ' (4 ", etc.) and shape consistent with corresponding rotary body generatrix be rational.0 °＜the Φ of scope of angle Φ＜180 °.And main carrier 4 and assistant carrier 4 ' (4 ", etc.) should be shapes, measure-alike and arrange with about 45 ° interval.Nature, each carrier 4 (4 ', 4 "; etc.) all should have and identical oppositely be supported on balance stem 8 on the axle 3 (8 ', 8 ", etc.) on the same geometrical plane, all should be consistent with a corresponding rotary body generatrix, all should be equipped with the light source 5 that links to each other with control module 6.

In this case, shape, the size of each balance stem 8 (8 ', 8 " etc.) and its corresponding vectors 4 (4 ', 4 " etc.) and to be equipped with the quantity of light source identical.

Be supported on the carrier on the same axle 3 and the increase of balance stem quantity along with these are paired, can produce stroboscopic effect under the situation that axle 3 rotations are further slowed down becomes possibility.Therefore, the inertia of motion parts has reduced, and the rotary body radius that light source 5 is limited has increased thereupon.When carrier and balance stem quantity increased, making increased carrier 4,4 ', 4 " and balance stem 8,8 ', 8 " etc. the rigidity and the stability on top necessitate, this point can be finished by increasing some mechanical component (not shown).

Install, maintain, repair all carriers 4,4 ', 4 for convenience " and take on the balance stem 8,8 ', 8 of carrier " etc., the structure of these all parts should be unified.Here need not to illustrate mounting condition, because these parts are known altogether for everybody in the prior art.

In order significantly to enlarge the quantity of advertising device, device of the present invention is equipped with (Figure 21 of a rotating driver 2 at least, 24) asessory shaft 3 ', in this case, axle 3 ' is spatially with respect to main shaft 3, rotate synchronously by a kind of suitable mode and axle 3, and, be equipped with at least with a carrier 4 that corresponding rotary body generatrix is consistent.Very clear, only shown two axles of this asessory shaft 3 ' in the accompanying drawing, purpose is to understand function of the present invention better, but in fact, a plurality of this asessory shafts 3 ' is arranged.In various inventive embodiments, preferably main shaft 3 and at least one asessory shaft 3 ' parallel placement, and by synchronous converyer 9 and rotating driver 2 for example gear and chain driver (Figure 20,21,22) link to each other.Two adjacent balancing shafves 3 _iWith 3 _I+1Between the distance A scope bigger because it can be equal to or greater than by light source limit apart from axis radius of a circle sum (maxR farthest _i+ maxR _I+1).So, the information of separating possess A 〉=maxR for showing simultaneously _i+ maxR _I+1The time, A is big more, and this device effect is superior more.Yet, in showing, when every pair of adjacent parallel axle 3 with the lower device operation instructions _iWith 3 _I+1On phase place synchronously and meet A 〉=maxR _i+ maxR _I+1The time, this device is specially adapted to advertisement.

In the simplest pattern of the present invention that shows in Figure 21, preferably each axle all has a pair of orthogonal main carrier 4 and assistant carrier 4 ', and the size difference of two carriers.Particularly, main carrier 4 can be made the shape of the circular arc of different radii, and still, assistant carrier 4 ' can not be made various circular arcs as vertical rod.Advise that above-mentioned each carrier all should be to there being supported balance stem 8.

The embodiment of the invention quite complicated state (Figure 22 and 23) in the example, this device is equipped with the parallel shafts 3 more than two; Every axle 3 all has the carrier 4 on identical reference position.Under this condition, suitable situation is:

Every axle 3 between first 3 and last root axle 3 removes main carrier 4, and the upright assistant carrier 4 ' bigger than main carrier 4 all should be arranged.

First axle and last root axle should have only a carrier 4, and its shape, size are with identical corresponding to the position of the main carrier on other 4.

At one of the embodiment of the invention more particularly (Figure 24) in the sample, this device is equipped with axle 3 two coaxial lines and spaced and axle 3 '; Every axle 3 or 3 ' all is equipped with a carrier 4 at least, and its shape is consistent with corresponding rotary body generatrix, and is positioned between the interval of axle 3 and spool 3 '.For the optical effect that obtains to assist, coaxial bobbin 3 and axle 3 ' by a between centers that is used to correct described axle 3 and axle 3 ' every and synchronization mechanism that control module 10 is housed transmit equipment, link to each other with same motor.

Should be understood that by means of described embodiment, will have the inventive embodiments of other different patterns in the parallel of same planar axes 3 and coaxial line mounting arrangement.Like this, the top that many parallel shafts is installed in an arbitrary polygon (there is no need equilateral) is possible.Therefore to reach gratifying optical effect, to two axles 3 of major general on same plane or Different Plane install at an angle by two axis.As a result, corresponding, axis is meeting at a bit or mutual the intersection.

Also can understand, power supply unit 7 power supplies will use an electromechanical transducer that is fit to that links to each other with control module 6 to LED source; Electromechanical transducer resembles a cover " ring-type brush " and to be positioned at light source 5 quantity that corresponding axis 3 connected consistent.Similarly, when using the light transmitting fiber end, use a suitable photoelectric commutator as light source.

Stroboscopic display device operation according to the present invention is as follows:

Irrelevant with the special pattern of embodiment, advertising message is all wanted Input Control Element 6, realize this purpose, the hardware that utilize some to know resembles keyboard (being used for input characters), scanner (being used for input picture), computer disc driver (being used to import prior ready prepd information) etc.Further, control module 6 has formed a series of command signal and has cut and cut out light source 5, and sends a ready signal and come starter gear.In this process, control module 6 is considered some or all above programming factors, wherein, the initial position of the carrier of the quantity of light source 5 and light source 5 can be arranged all.When starting rotating driver 2, control module 6 is being controlled the rotation of output shaft 3, and the rotation of turning axle is reached the speed of an appointment according to described a series of order.If a plurality of axles 3 are arranged, only when every axle had reached the speed of its appointment, advertisement process just began to carry out.

Because the image of advertisement (frame) is changed with the speed of persistence of vision time of surpassing the people, so that spectators see the effect that at least a image (picture is or/and literal) freely suspends aloft on sightless carrier surface on the illusion.Which kind of pattern no matter this device be designed to, and all can obtain this basic effect.In the simplest pattern (Fig. 1 to 3, irrelevant and Fig. 4 to 9) with the light source of balance stem 8 in other words, under perfect condition, this effect can be in sight.Along with carrier 4 narrow down and with≤16s ^-1Speed motion, this carrier has disappeared from spectators' sight line on illusion, and vivo " suspension " aloft for symbol and lines clearly, the commodity and the service that the potential customer are attracted to advertisement come up, and this symbol and lines are to form in the synchronous flicker that 5 rotations of several groups of light sources produce.Section thickness d when the light emission surface of the most approaching total light source 5 of the thickness of carrier 4 _PlsThe time, and when the width B of this carrier than the distance axis 3 axis radius of a circle farthest that limits by light source 5 more hour, just can reach wonderful effect more.

Install in the more complicated design at this, described effect can be replenished the attractive force that improves spectators by other lighting effects.For example, have as shown in figure 10 according to Fig. 1 to 3 and balance stem 8 in the device operation of light source 5 designs, the secondary light source 5 of balance stem 8 produced visible band on the illusion and the illusion that limits round light source 5 by main carrier 4 on sightless rotary body (Figure 11).By the combination of band and described rotary body, can show the different splicing parts and the various overlapped information of identical information simultaneously.If the negligible amounts of the light source 5 of balance stem 8, common display text of this band and simple picture, preferably with mobile linear pattern, and invisible rotary body will show more complicated information on the described illusion.Device according to the present invention will provide more complicated lighting effects what carrier 4 and/or balance stem 8 (Figure 14) were furnished with secondary light source 5.So the device of design can show the Word message (normally by the light source scintillation generation of the both sides of the balance stem 8 of operation in accordance with regulations) of simple stereo-picture (the basic image of backlit usually, image are that the flicker by the outside of carrier 4 and internal light source 5 produces) and light shading.

Along with the rotation of axle 3, be x with respect to its external light source 5 with the distance at the internal light source 5 of carrier 4 or balance stem 8, angle is α when rotating, the result of opti-cal illusion makes it possible to obtain above-mentioned auxiliaring effect (Figure 15 and 16).Can understand that carrier 4 or balance stem 8 width radially are wide more, x and α are just important more, and replacing of the outstanding or deepening of advertising message is just more remarkable.

If axle 3 has two pairs or the four pairs of carriers 4 (Figure 18,19, with Figure 17 relatively), it all is possible that the rotational speed of axle 3 reduces twice or four times.When rotational speed descended, carrier 4 may flash in the motion, but can successfully cover up by the auxiliary or decoration details of information or the remarkable expansion (expanding one meter or bigger to) of display text and/or image.

It is a kind of more effective that the device of Figure 21 provides, the picture clearly and the literal (Figure 22) of the unusual especially attracting solid of interting mutually and/or replacing.Wherein, the pair of parallel axle 3 _iWith 3 _I+1Be synchronous on phase place.And with axial spacing A＜maxR _i+ maxR _I+1Intert the location and/or transposition can be carried out with different speed according to the program of the control module 6 of packing into.Be positioned at the blend of colors of various carriers 4 on the disalignment 3 and/or the light source 5 on the balance stem 8 and/or change manyly more, the raising of effect is obvious more.

Moreover, Figure 22 device shown formed one show fixing or mobile message (Figure 23) in the sightless fluctuation of illusion " screen ".When two or more parallel shafts 3 rotated with same rotational speed, identical upright carrier 4 had formed the assembly of sightless cylindrical surface on the illusion.This assembly on whole surface or the part on surface show with the form of mutual splicing and fluctuation and the various piece of identical information show that perhaps at least one runs through the fluctuation shape information of whole " screen ".Certainly, if appropriate software is arranged, the translational speed of the various piece of whole information or information and/or direction can be adjusted arbitrarily.

If the axle 3 in the middle of each of device all is equipped with long assistant carrier 4 ' and first and last root axle 3 when being equipped with the same carrier of main carrier 44 ', can produce two equidistant " screens " that freely suspend aloft.

And depart from approximately in the front at screen place+/-spectators in the model of 45 can see the information that each several part splices mutually (particularly image with literal) simultaneously on screen; Perhaps spectators can see information different on each screen simultaneously from different angles.

Further in operation, Figure 24 device shown can change the interspersed degree of depth of the height or the change different images of identical information.This operation can realize by the interval that changes between the axle 3 and 3 ' that control module 10 changes coaxial line.

At last, be noted that axle 3 rotation stably along with driver 2, because the very little inertia of pointolite, in any pattern of embodiment, can be by using suitable software with any speed and/or direction display message.

Commercial Application

According to device of the present invention, be easy to produce in batches so that the advertiser of middle and small scale commerce can Utilize it. Can show any picture and/or Word message and produce the marvellous effect that freedom of the air suspends Really. This marvellous effect is produced as feeling from a kind of advertising message of called optical imaging, to obtaining Get the commodity of institute's advertisement and the psychological application that service (particularly new) sensation subconsciousness changes. In exhibition and the trade fair, the device of simple designs is used for showing the trade mark of advertising message according to the present invention With being extensive use of of service mark, made things convenient in fact the exhibitor to attract visitor's attention.
