Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A portion enlarged drawing of Fig. 1;

Fig. 3 is circuit structure embodiment of the present utility model;

Fig. 4 is an imaging schematic diagram of the present utility model.

Embodiment

Referring to Fig. 1,2, the flabellum 2 that fan has a handle 1 and links to each other with handle is equipped with battery folder 3 in handle 1, for placing battery.On flabellum 2, be installed with a circuit board 4, be welded with row's light emitting diode 5 on the circuit board.Present embodiment is installed with edge at flabellum 2 with circuit board 4, and light emitting diode 5 is arranged along the tangential direction at flabellum edge, and this arrangement is content with very little that each light emitting diode is agitated along with flabellum most and the movement locus that forms is parallel to each other and the condition of non-overlapping copies.Except position shown in Figure 1, also circuit board 4 and whole row's light emitting diode 5 can be arranged on the B place or the C place at flabellum edge, effect is the same.Be welded with integrated circuit on the circuit board, the power end of integrated circuit is communicated with the battery folder 3 of handle by lead 6, and as conventional design, present embodiment also is provided with power switch 7.Referring to Fig. 3, but integrated circuit 8 has one group of level output pin L1～L16 of driven for emitting lights led lighting, this group level output pin is connected with row's light emitting diode, present embodiment is formed a row by 16 light emitting diode T1～T16, integrated circuit 8 correspondingly also has 16 level output pins, each level output pin is pressed the intrinsic program of IC interior, with the different drive level of certain sequencing output pulse width, the drive level of present embodiment is a low level, controls luminous in the different time periods of different light emitting diodes and extinguishes state with this.Because the production technology of integrated circuit is quite ripe at present, integrated circuit manufacturing plant has had the ability of making integrated circuit according to user's requirement, and the model that can press user's hobby definition integrated circuit, therefore the used integrated circuit of the utility model there is no specific model, as long as tell integrated circuit manufacturing plant the output rule of each level output pin of driven for emitting lights diode, just can customize the integrated circuit of accomplished the utility model function, different level output rules form different patterns or literal.The peripheral circuit of integrated circuit 8 is not as the criterion with Fig. 3, but is as the criterion by the actual integrated circuit that produces of integrated circuit manufacturing plant.Below in conjunction with Fig. 4 principle of work of the present utility model is described.For ease of explanation, below light emitting diode is called " LED ".Fig. 4 represents when fan is agitated, the movement locus of the whole row LED that sees from the D direction of Fig. 1.The numbering of each LED is represented in a column of figure " 1 "～" 16 " from the bottom to top, the left side among the figure, is defined as the Y coordinate; When the following whole row of a column of figure " 1 "～" 16 " expression LED from left to right moves from left to right with fan,, be defined as the X coordinate at the position coordinates of different time points.Each LED is in the available coordinate of different time points (X, Y) expression like this.Along with agitating of fan, in the reference position of X=1, whole row LED all extinguishes, that is LED (1,1)～(1,16) all do not have bright, when X=2, LED (2,1), LED (2,2) and LED (2,15), LED (2,16) lighted together, when X=3, LED (3,1)～(3,16) lighted entirely, the rest may be inferred, just can present the image of letter " I " when X=5 in people's persistence of vision, when overall process finishes, that is during X=16, in people's persistence of vision, just can merge letter " IT ".If show other pattern, then only need to find out the luminescence law of LED according to above-mentioned principle, just can obtain showing the integrated circuit of required image to the customization of integrated circuit manufacturing plant.Because the translational speed when LED agitates with fan is about 600mm/ second, so the flash time of LED can be controlled in about about 0.002～0.0033 second.

Because agitating of fan is a kind of to-and-fro movement, therefore be preferably in a triggering of design pin in the integrated circuit, and be connected a motional induction switch with this triggering pin, when fan direction of motion is reversed, trigger integrated circuit is controlled LED by opposite sequential sequence of light by inductive switch, for example among Fig. 4 when fan is turned left travelling backwards by the right side, trigger integrated circuit by inductive switch and demonstrate " T " earlier with opposite sequential control LED and demonstrate " I " again, can avoid shown visual opposite each other of fan two-way process like this.But the inductive switch of this paratonic movement direction can have been bought on market.Certainly, for saving cost, simplified structure, also inductive switch can be set, though can demonstrate forward and the reverse image that overlaps like this, the analysis of process human brain also can therefrom identify the figure of forward, still can realize the purpose of this utility model.
