Abstract
The utility model provides a vision persistence demonstrating instrument in order to solve a problem that teaching demonstration effect is affected substantially due to lack of a good demonstration instrument used for demonstrating vision persistence in prior middle and primary physics teaching. The vision persistence demonstrating instrument includes a pedestal and a support arranged on the pedestal. The support is provided with a rotary LED array board. A rotary shaft of the LED array board is connected with a motor. The motor is arranged in the support. The vision persistence demonstrating instrument provided by the utility model is simple in structure. By rotating the LED array board, vision persistence is demonstrated. And the demonstration effect is distinct and the proceeding of physics teaching demonstration is facilitated substantially.
Description
Technical field
The utility model relates to teaching aid technical field, specifically, relates to a kind of persistence of vision demonstrator.
Background technology
Visual persistence phenomenon (Visual staying phenomenon, duration of vision) claims again " sunset glow effect ".Human eye is when observing scene, and light signal imports cerebral nerve into, need be through one of short duration period, and after the effect of light finishes, visual image does not disappear immediately, and this residual vision claims " after image ", and this phenomenon of vision is called as " persistence of vision ".
This be light vision that retina is produced after light fails, still retain the phenomenon of a period of time, its concrete application is shooting and the projection of film.Reason is that the reaction velocity by optic nerve causes, and its duration is 1/24th second.It is the basis that the visual medias such as animation, film form and propagate.Vision is actually the crystalline lens imaging by eyes, photosensory cell sensitization, and light signal is converted to neuroelectricity, pass brain back and cause human visual.The sensitization of photosensory cell is that the formation of photopigment needs certain hour by some photopigments, and this has just formed the mechanism of suspenopsia.
In middle and primary schools' physics teaching, for allow student passable visual persistence phenomenon progressively learn its principle, be preferably by specific demonstrator and impart knowledge to students, and rarely have now, a kind ofly can, for the demonstrator of demonstration visual persistence phenomenon, greatly hinder the demonstration effect of teaching preferably.
Utility model content
The utility model is in order to solve in the process of existing middle and primary schools physics teaching, owing to rarely having now, a kind ofly can greatly hinder the problem of the demonstration effect of teaching for the demonstrator of demonstration visual persistence phenomenon preferably, and a kind of persistence of vision demonstrator is provided.
The technical matters of the required solution of the utility model, can be achieved through the following technical solutions:
A demonstrator, is characterized in that, comprising: base, be arranged on the bearing on base, and described bearing is provided with rotating LED array plate, and the rotating shaft of described LED array plate connects a motor, and described motor is arranged in bearing.
In the utility model, described base is box-like, comprises base upper cover and base lower cover, and described base upper cover buckles under base and covers.
Described base upper cover is provided with base plate, and described bearing is arranged on base plate.
Under described base, cover and be provided with power interface, described base upper cover is provided with power switch.
On described base upper cover, be also provided with the regulator potentiometer that regulates motor speed.
In the utility model, described bearing is provided with the spring carbon brush of powering to LED array plate, with easier realization, LED array plate is powered.
In the utility model, described bearing is provided with transparent protective shield around, so that LED array plate is protected.
Described transparent protective shield is tubular.
Persistence of vision demonstrator of the present utility model, structure is simplified, and by rotating LED array plate, visual persistence phenomenon is demonstrated, and is demonstrated successful, is greatly conducive to the carrying out of physics teaching demonstration.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Purport of the present utility model is, by in existing middle and primary schools Physics Learning process, the analysis of visual persistence phenomenon demonstration demand, discovery due to rarely have now a kind of preferably can for demonstration visual persistence phenomenon demonstrator, the problem that has greatly hindered the demonstration effect of teaching, provides a kind of persistence of vision demonstrator to address the above problem by the utility model.
Referring to Fig. 1, persistence of vision demonstrator of the present utility model, comprise base, other assemblies of whole persistence of vision demonstrator are installed on base, in the utility model, adopted a kind of preferably mode, base comprises base lower cover 11 and base upper cover 12, and it is box-like that base is, base upper cover 12 buckles on base lower cover 11, can be used for taking in each assembly of persistence of vision demonstrator in base lower cover 11.
In present embodiment, base upper cover 12 is provided with bearing 2, and bearing 2 is provided with rotating LED array plate 3, and the rotating shaft of LED array plate connects a motor (not illustrated), and motor is arranged in bearing 2, makes the profile of whole demonstrator comparatively attractive in appearance.In order realizing, LED array plate 3 to be powered, spring carbon brush (not illustrated) can be set on bearing 2, make the power supply mode of LED array plate 3 comparatively simple.
In present embodiment, base upper cover 12 is provided with base plate 4, and bearing 2 is arranged on base plate 4, base lower cover 11 is provided with power interface (not illustrated), base upper cover 12 is provided with power switch 121, meanwhile, is also provided with the regulator potentiometer 122 that regulates motor speed on base upper cover 12.
In addition, in the utility model, bearing 2 is also provided with transparent protective shield 5 around, and so that LED array plate is protected, present embodiment has adopted preferably mode, and transparent protective shield 5 is tubular.
Persistence of vision demonstrator of the present utility model, structure is simplified, and by rotating LED array plate, visual persistence phenomenon is demonstrated, and is demonstrated successful, is greatly conducive to the carrying out of physics teaching demonstration.
Below only with regard to the utility model preferred embodiment, be described, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.In a word, all various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
