Description

Technical Field

[0001] The utility model belongs to the technical field of teaching equipment, and in particular relates to a light dispersion teaching demonstration device. Background Art

[0002] In the middle school physics course, optical knowledge is an important learning component of the course. The demonstration experiment of white light passing through a prism and being divided into red, orange, yellow, green, cyan, blue, and purple monochromatic light is one of the important demonstration experiments of the course.

[0003] At present, in the field of education and popular science, the dispersion phenomenon of light is generally demonstrated by using pictures or slides. The light dispersion teaching demonstration tool usually places a prism mounted on a U-shaped frame where there is a light source. The light source passes through the prism to cause the light dispersion phenomenon. A light screen is set in front of the prism to present the spectrum generated by the prism on the light screen. However, the light screen is too small and the light emitted by the light source will affect the students' observation effect, thereby affecting the demonstration effect and teaching effect. Students are also unable to dynamically experience the changes in light color, and it is difficult for students to have a deep understanding and impression of light dispersion.

[0004] Therefore, we propose a light dispersion teaching demonstration device to solve the above technical problems. Utility Model Content

[0005] In order to solve the technical problems of poor demonstration effect and poor teaching effect of the light dispersion teaching demonstration tools in the above-mentioned prior art, the utility model provides a light dispersion teaching demonstration device.

[0008] By adopting the above technical scheme, when the utility model is in use, the strong light source emits light by turning on the power supply, and the light refraction phenomenon is generated through the prism component. The refracted light is projected from the light outlet to the indoor floor, which is convenient for observation. The design of the light shield effectively reduces the interference of the strong light source on the refracted light, avoiding affecting the demonstration effect and the teaching effect. In the teaching process, the angle of the prism component is rotated to realize the convenient adjustment of the light incident angle, so that students can observe the process of decomposing complex light into monochromatic light. When light of different colors is projected, it brings fun to the students' classroom, and shows the three-dimensional rainbow more vividly and intuitively, bringing a sense of reality to the students. It intuitively shows to the students that the dispersed monochromatic light can indeed achieve white light after mixing, and intuitively shows to the students that different monochromatic lights can achieve different mixed colors after mixing, so that students have a deep understanding and impression of the dispersion of light and the mixing of light, thereby improving the teaching effect.

[0011] In a further technical solution, a mounting groove matching the prism is provided on one side of the first mounting shell and the second mounting shell that are close to each other.

[0012] By adopting the above technical solution, the prism is installed in the mounting grooves of the first mounting shell and the second mounting shell, so that the prism can be easily disassembled and assembled, and prisms with different refractive indices can be replaced to perform light dispersion teaching demonstrations. The degree of separation of different colored lights through prisms with different refractive indices is different, so as to stimulate students' interest in learning.

[0013] In a further technical solution, one end of the second rotating shaft extending out of the box body is connected to a rotating handle.
