Advantage and good effect that the utility model LED shakes rod be: owing to be provided with single-chip microcomputer and switching key, selected the LED LED light lamp of high brightness, low-power consumption, so reduced energy resource consumption and cost.Adopt simultaneously lithium battery as built-in power supply, structure is small and exquisite, is convenient for carrying, and is convenient to taking with putting.In addition, adopt the LED LED light lamp, show to have dynamic effect, utilize the eye storage characteristic of human eye, the pattern displaying of various magnificent mansion can be arranged, and show various character patterns.

Be elaborated with reference to accompanying drawing below in conjunction with embodiment.

Description of drawings

Fig. 1 is the construction profile schematic diagram that the utility model LED shakes rod;

Fig. 2 is the circuit structure block diagram that the utility model LED shakes rod;

Fig. 3 is the circuit theory diagrams that the utility model LED shakes rod.

The specific embodiment

Describe the embodiment that the utility model LED shakes rod in detail below in conjunction with accompanying drawing.

With reference to Fig. 1, the LED that the utility model provides shakes rod, comprises the barred body 4 with handle 5.LED LED light lamp 3, power switch S, switching key S3 and the mercoid switch S2 of high brightness, low-power consumption are installed on the barred body 4.16 LED LED light lamps 3 are along on the uniform surface that is installed in barred body 4 of axis direction.Mercoid switch S2 is installed in the front end of barred body 4, and power switch S and switching key S3 are installed on the handle 5.

Shake among the embodiment of rod at the utility model LED, power supply is the built-in 3.7V lithium battery 1 of barred body 4.One single-chip microcomputer 2 is installed in the barred body 4.With reference to Fig. 2 and Fig. 3, it is the chip of STC89C52 that single-chip microcomputer 2 adopts model.Mercoid switch S2 links to each other respectively with single-chip microcomputer 2 with switching key S3, mercoid switch S2 output interrupt signal is to the P3.0 pin of single-chip microcomputer 2, the P0.0 pin of single-chip microcomputer 2 to the control signal of P0.7 pin and the output of P2.0 to P2.7 pin is connected to respectively each LED LED light lamp 3, refreshes conducting and the shutoff of LED light emitting diode 3 with different frequencies.Switching key S3 outputs control signals to the P3.1 pin of single-chip microcomputer 2, and single-chip microcomputer 2 switches demonstration different image or literal.

The utility model LED shakes rod take STC89C52 High Performance SCM 2 as control core, produce interrupt signal by mercoid switch S2, utilize the eye storage characteristic of human eye, the swing stick that at every turn shakes all will stay twilight sunset in human eye, thereby enrich people's visual pattern picture.

There is visual persistence phenomenon in people's eyes, just because of eyes are slow in reacting, have just enriched people's visual experience.The LED swing stick has utilized the eye storage characteristic of human eye, when the LED swing stick swings to diverse location, make way for the different row of the LED LED light lamp 3 demonstration two dimensional images on the straight line, utilize the visual persistence effect of human eye, realize that graph scanning shows.The control of output signal frequency realizes that by single-chip microcomputer 2 light on and off that 16 LED light lamps 5 are carried out different frequency refresh.When shaking, because people's persistence of vision principle, can shake the zone at LED LED light lamp 3 and produce a visual plane, LED LED light lamp 3 refreshing by different frequency in visual plane, can in shaking the zone, produce image, thereby reach the effect that conveys a message at this visual plane.Specifically, the required time is 0.8 second to known swing stick from a side oscillation to opposite side, is divided into 64 parts to 0.8 second, and then the picture displaying time of each row is 0.0125 second.The byte that each row is corresponding two 8, corresponding 16 the LED LED light lamps 3 of 16 bit bytes, then corresponding row of display graphics in every a time then can obtain complete figure and show.

Shake among the embodiment of rod at the utility model LED, adopt the singlechip interruption mode to realize the partial function of system according to top principle, namely use the interruption of switching key S3 control single chip computer 2, single-chip microcomputer 2 output different frequencies control signal to LED LED light lamp 3, with conducting and shutoff that different frequencies refreshes LED LED light lamp 3, pattern and the literal of each picture disply are all different.In the design of program, all have breakthrough on the reasonable arrangement of pattern, be well science popularization teaching aid and a commodity present.

The concrete using method that the utility model LED shakes rod is:

Turn on the power switch S and mercoid switch S3 just can see: system starts, and each LED LED light lamp 3 has become a line afterwards in ceaselessly flicker, at this moment, presses switching key S3, has just showed the effect of putting into line, can see different curves.

The effect of back will just can be seen in the situation of shaking.Shake LED and shake rod, in the process of shaking, the bright LED LED light lamp 3 that becomes line has become face with regard to bright, at this moment, presses switching key S3, has just showed that line becomes the effect of face, can see different curved surfaces.

The utility model LED shakes rod, assignment order at single-chip microcomputer 2 output different frequency control LED LED light lamps 3 has been done Renewal Design, when pressing switching key S3, the pattern displaying that various magnificent mansion can be arranged, and show various character patterns, as: " mother's Mother's Day is happy! " " Valentine's Day is happy! " " happy birthday " etc.

Embodiment recited above is described preferred embodiment of the present utility model, is not that design of the present utility model and scope are limited.Under the prerequisite that does not break away from the utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
