Problems solved by technology

However, due to the smoother surface of the blackboard, students in the classroom often have the feeling that when the intensity of sunlight is high, especially in summer when the light is bright, the sunlight with high intensity of glare enters the classroom obliquely through the window. In the future, it will often form reflections on the blackboard, which not only affects the efficiency of students in class, makes students unable to study normally, but also aggravates the visual fatigue of students for a long time, causing damage to students' vision

Abstract

The invention discloses an anti-reflection device for education and teaching, and belongs to the technical field of anti-reflection devices for teaching. The anti-reflection device comprises a shell, a blackboard is arranged in the shell, a frame is arranged at the sides of the blackboard, sliding blocks are arranged at the two sides and the upper end of the frame, and sliding rails corresponding to the sliding blocks are arranged on the inner side wall of the shell. According to the anti-reflection device, a shading plate is arranged, when sunlight is strong, the shading plate is erected, and fixing clamping rods are rotated to be clamped into clamping grooves of clamping blocks to form fixing, so that fixing is easy, convenient and fast, and light reflection of the blackboard disappears; however, after the shading plate is erected, light of the blackboard is insufficient, and the condition that the blackboard cannot be seen clearly exists; an LED lamp is used for increasing the brightness of the blackboard and can be used when the blackboard cannot be see clearly and can also reinforce light when a light source is insufficient at night; and a solar panel collects solar energy, converts the solar energy into electric energy and provides sufficient electric energy for the LED lamp, so that the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of anti-reflection devices for teaching, and in particular relates to an anti-reflection device for education and teaching. Background technique [0002] Present primary and middle school classrooms generally still use blackboard and chalk for teaching. The blackboard is positioned at the front of the classroom, and the teacher writes the teaching content on the top, and the students watch it below. However, due to the smoother surface of the blackboard, students in classrooms often feel that when the intensity of sunlight is high, especially in summer when the light is bright, the sunlight with high intensity of glare enters the classroom obliquely through the window. In the future, it will often form reflections on the blackboard, which not only affects the efficiency of students in class, makes students unable to study normally, but also aggravates the visual fatigue of students for a long time, causing d...
