Abstract

A blackboard convenient for teaching English. It mainly solves the problem that lighting lamps are often arranged in the space above the blackboard in the existing classrooms, which also causes reflection of the blackboard while illuminating, and cannot improve the brightness of the blackboard. It is characterized in that: the blackboard body (4) is evenly distributed around the fixed frame (1), wherein, the fixed frame (1) is provided with a number of light slots (2) for the LED lighting lamp to be embedded and to provide power supply, A number of LED lighting lamps (3) are fixed in the lamp groove (2); the blackboard also includes a rectifier circuit that provides working power for the LED lighting lamps and a remote control circuit that controls the opening and closing of the LED lighting lamps. The two circuits They are all located in the sandwich layer of the fixed frame (1) and controlled by a remote control switch. The blackboard used for English teaching can illuminate the entire blackboard when the teacher writes on the blackboard, while avoiding the problem of reflection on the blackboard.

Description

A blackboard convenient for English teaching

technical field

The utility model relates to an auxiliary teaching office device used in English teaching.

Background technique

At present, the blackboards used in the field of English teaching to provide teachers with blackboard writing are often equipped with lighting lamps in the upper space of the blackboard, but they cause reflections on the blackboard while lighting, and cannot improve the brightness of the blackboard. In particular, the classroom is large, and it is difficult for the students in the back row and the side to read the writing on the blackboard, which greatly affects the teacher's teaching.

Contents of the invention

In order to solve the technical problems mentioned in the background technology, the utility model provides a blackboard which is convenient for English teaching. This kind of blackboard is specially designed for the teaching of English teachers. It causes reflection, which better guarantees the learning quality of students and the teaching process of English teachers.

The technical scheme of the utility model is: this kind of blackboard convenient for English teaching includes a blackboard body, and its unique feature is that there are fixed frames evenly distributed around the blackboard body, wherein there are several LED lights on the fixed frame. The lighting lamp is embedded in and provides a light slot for power supply, and several LED lighting lamps are fixed in the lighting slot; the blackboard also includes a rectifier circuit that provides working power for the LED lighting lamp and a remote control circuit that controls the opening and closing of the LED lighting lamp. The above two circuits are all located in the sandwich layer of the fixed frame and controlled by a remote switch.

In addition, in order to facilitate the use of teachers, each group of lighting lamps is connected in parallel. If one group of lamps cannot work normally, the other groups can still provide lighting. Moreover, before the teaching begins, the teacher can control the work of each group of lighting lamps through the remote control switch.

The utility model has the following beneficial effects: each group of LED lighting lamps is evenly distributed around the blackboard, and the lighting lamps can be turned on by a remote control switch when needed, so that students can see the handwriting on the blackboard clearly, and the reflection phenomenon of the blackboard is also alleviated. The device has the advantages of simple structure, convenient use and strong practicability.

Description of drawings:

Fig. 1 is a structural representation of the utility model.

In the figure, 1-fixing frame, 2-light groove, 3-LED lighting, 4-blackboard body.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Fig. 1, this kind of blackboard convenient for English teaching includes a blackboard body 4, which is unique in that: the blackboard body 4 is evenly distributed around the fixed frame 1, and the fixed frame 1 has a sandwich layer. Among them, the fixed frame 1 is provided with a plurality of lamp slots 2 for LED lighting lamps to be embedded and to provide power supply, and several LED lighting lamps 3 are fixed in the lamp slots 2; the blackboard also includes a working power supply for the LED lighting lamps. A rectifier circuit and a remote control circuit for controlling the LED lighting lamp to be turned on and off, both of the two circuits are located in the sandwich layer of the fixing frame 1 and controlled by a remote control switch.

In addition, in order to facilitate the use of teachers, the lighting is evenly distributed, so that there will be no difference in light and shade around the blackboard; and there is a lampshade above the LED lighting, which greatly reduces the reflection of the blackboard, so it is easy for students to see clearly Teacher's blackboard.

In addition, since each group of lighting lamps is connected in parallel in the working circuit, when one group of lighting lamps fails to work normally due to an accident, the work of other groups will not be affected. Therefore, the quality of lighting is better guaranteed.

Claims (1)
