Description

Technical Field

[0001] The utility model belongs to the technical field of art light and shadow teaching, and particularly relates to an art light and shadow teaching auxiliary device. Background Art

[0002] The teaching of light and shadow is an important part of art teaching. It helps students understand the expression of object shape, volume, space, depth, texture and the creation of emotions on two-dimensional pictures, thereby enhancing the realism and artistic expression of the picture. The spatial adjustment of light sources is crucial in art light and shadow teaching. Art light and shadow teachers need to simulate the light and shadow presented by different objects in nature under different angles and directions of light. This requires the use of corresponding art light and shadow teaching auxiliary devices. However, most of the common art light and shadow teaching auxiliary devices can only perform single angle rotation adjustment. In real life, the source direction of the light source is changeable, which leads to the poor effect of the light source simulated by the auxiliary device, and it is impossible to restore the lighting conditions in natural conditions to the greatest extent, making it difficult for teachers to effectively explain in teaching, resulting in poor teaching results.

[0003] Secondly, some students lack imagination. Without physical objects for teaching explanations, they find it difficult to understand the abstract content taught by the teacher, resulting in poor learning results and difficulty in keeping up with the teaching progress.

[0004] In summary, the art light and shadow teaching auxiliary device that can only perform a single angle adjustment function has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
