Abstract
The utility model discloses a vision demonstrating device which belongs to the technical field of optical instrument manufacture. The vision demonstrating device consists of an object stage, a frequency modulation light source and a fan, wherein, the frequency modulation light source and the fan are installed on the object stage, and the frequency modulation light source and a head of the fan are corresponding with each other. The relative distance between the frequency modulation light source and the fan is 50cm to 80cm. The vision demonstrating device is very useful for demonstrating and experimenting for elementary and middle school students and nursery school children or for the scientific popularization work at scientific popularization propaganda department. As a hallucination vision demonstrating device, the vision demonstrating device increases interest for people, also deepens the perceptual knowledge towards optical vision effect and has the advantages of simple structure and convenient usage, etc.
Description
Technical field
The utility model discloses a kind of vision demonstration device, belongs to optical instrument class manufacturing technology field.
Background technology
So far, also do not have special device to demonstrate this visual phenomenon, even when doing this lecture experiment, only be now call in fan, the variable ratio frequency changer lamp is demonstrated temporarily, give in the teaching and make troubles.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of vision demonstration device simple in structure, easy to use.
The utility model is achieved through the following technical solutions:
The utility model is made up of objective table, frequency modulation light source and fan, and wherein: frequency modulation light source and fan are installed on the objective table, and the fan of frequency modulation light source and fan is corresponding.
The relative distance of described frequency modulation light source and fan is 50cm～80cm.
The utility model is done lecture experiment for students in middle and primary schools, the children of kindergarten, and it is very useful perhaps doing scientific popularization work in popular science propaganda department.As a kind of illusion vision demonstration device, make people when heightening the enjoyment, deepened perceptual knowledge to effect optical visual.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 frequency modulation light source, 2 fans, 3 support boards.
Embodiment
Embodiment: structure as shown in Figure 1, the utility model is made up of objective table, frequency modulation light source 1 and fan 2, wherein: frequency modulation light source 1 and fan are installed on the objective table, and the fan of frequency modulation light source and fan is corresponding.Described frequency modulation light source 1 is 50cm～80cm with the relative distance of fan 2.Objective table is as the support board among the figure 3.
During use, open electric fan 2, wait electric fan 2 slow-roll stabilizations after, open the switch of light source 1, the frequency of regulating light source 1 is gradually observed the fan sheet of fan 2, you can find that former unclear fan sheet can see clearly, it is more and more slower to change ground as the fan sheet.Even under the light source irradiation of a certain frequency, sector static is motionless.
Claims (2)
1, a kind of vision demonstration device is made up of objective table, frequency modulation light source and fan, and it is characterized in that: frequency modulation light source and fan are installed on the objective table, and the fan of frequency modulation light source and fan is corresponding.
2, vision demonstration device according to claim 1 is characterized in that: the relative distance of described frequency modulation light source and fan is 50cm～80cm.
