Abstract
The utility model relates to a teaching aid of middle school teaching usefulness, specifically speaking is carousel formula persistence of vision demonstrates appearance. Including box, driving shaft and the driven shaft of level setting on the box, driving shaft and driven shaft all support on the box through the bearing and through the pulley drive connection, the outer end fixed mounting of driven shaft has carousel and electrical store, and carousel and electrical store are the disc casing with the coaxial setting of driven shaft, and the carousel adoption transparent material make, and fixed mounting has many LED lamp strips in the inner chamber of carousel, LED lamp strip comprises a plurality of radial distribution's LED bulb, install the battery in the electrical store and be used for driving the dirver circuit board of LED lamp strip. Its simple structure, easy preparation, easy operation can explain in the teaching very directly perceivedly and improve persistence of vision's principle interest in learning, strengthen learning result.
Description
Technical field
This utility model relates to the teaching aid of middle school teaching, specifically rotating disc type persistence of vision demonstrator.
Background technology
Human eye when observing scene, optical signal successor cerebral nerve, need to be through one of short duration period, after the effect of light terminates, visual image disappears the most immediately, and this phenomenon of vision is then referred to as " persistence of vision ".In the middle school teaching stage, the multidisciplinary principle relating to persistence of vision or the application such as " naturally ", " physics ", " physiological hygiene ".But owing to lacking demonstration instrument directly perceived, effective, it is difficult to the learning interest of mobilizing students, knowledge point is grasped the most firm, it is more difficult to play creative application.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, easily making, rotating disc type persistence of vision demonstrator simple to operate, reaches to explain intuitively the purpose of persistence of vision principle to student, in order to improves learning interest, consolidate learning outcome.
In order to reach object above, the used technical scheme of this utility model is: rotating disc type persistence of vision demonstrator described in the utility model, including casing, the driving shaft being horizontally set on casing and driven shaft, described driving shaft and driven shaft are all connected on casing and by pulley drive by bearings, the outer end of described driving shaft is provided with hands handle, the outer end of described driven shaft is installed with rotating disk and electrical store, described rotating disk and electrical store are the disc housing being coaxially disposed with driven shaft, described rotating disk uses transparent material to make, the inner chamber of rotating disk is installed with many LED lamp bar, described LED lamp bar is made up of multiple radially-arranged LED bulb；Described electrical store is provided with battery and for driving the drive circuit board of LED lamp bar.
Described LED lamp bar has 2-4 root, is evenly distributed in rotating disk.
The beneficial effects of the utility model are: its simple in construction, easily make, simple to operate, teaching can be explained the principle of persistence of vision the most intuitively, improve learning interest, consolidate learning outcome.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Detailed description of the invention
As shown in Figure 1, rotating disc type persistence of vision demonstrator described in the utility model, the driving shaft 2 including casing 1, being horizontally set on casing 1 and driven shaft 3, described driving shaft 2 and driven shaft 3 are all connected on casing 1 and by pulley drive by bearings, the outer end of described driving shaft 2 is provided with handle 4, utilizing handle 4 to rotate driving shaft 2 can drive driven shaft 3 to rotate, and uses the belt pulley of different-diameter can change the rotating speed of driven shaft 3, thus obtains higher rotary speed.The outer end of described driven shaft 3 is installed with rotating disk 5 and electrical store 6, described rotating disk 5 and electrical store 6 are the disc housing being coaxially disposed with driven shaft 3, described rotating disk 5 uses transparent material to make, being installed with many LED lamp bar 7 in the inner chamber of rotating disk 5, described LED lamp bar 7 is made up of multiple radially-arranged LED bulb；Described electrical store 6 is provided with battery and for driving the drive circuit board of LED lamp bar 7.This drive circuit board is prior art, is not described in detail at this.
For obtaining best demonstrating effect, described LED lamp bar 7 has 2-4 root, is evenly distributed in rotating disk 5.
During use, drive circuit board lightening LED lamp bar 7 produces different point source effects, utilizes handle to rotate rotating disk 5, along with the raising of rotating speed, then can see the effect that persistence of vision is formed on rotating disk 5.
