The working principle of the triangular pyramid laser pointer from Wallis Lucy's blog

Triangular pyramid red laser pointer, including laser pointer body, built-in circuit, laser pointer body is equipped with laser, wireless charging coil, light sensor, PPT display, shell, pen head retractable button, touch screen contact, pen head, touch screen contact cover, Laser pointer handheld terminal, the built-in circuit is equipped with electric and magnetic conversion modules, wireless charging modules, batteries, main control circuits, wireless network modules, storage modules, single-chip microcomputers, power prompt modules, laser generation modules, touch feedback modules, and drive modules , Light sensor module, display module, the utility model has simple structure, convenient use, diversified functions, high user experience, small volume, convenient for users to put in their pockets and carry them, and the triangular pyramid shape is beneficial to prevent the laser pointer from slipping and losing , To avoid unnecessary embarrassment caused by the pen slipping on important occasions.

With the continuous advancement of science and technology, laser 20000mw are widely used in education and business presentations. However, because traditional laser pointers mostly use batteries as energy sources, it is not conducive to energy saving and environmental protection. In addition, in ordinary teaching mode, teachers will also Using traditional teaching rods to guide students to analyze and teach key issues, it is necessary to frequently change the teaching aids in their hands, which brings a lot of inconvenience to teachers. In actual teaching practice, the teaching rod can clearly indicate the position of the blackboard, especially the blackboard indicating high places. When applicants go to school, teachers often use single-function tools such as books and sticks, but such tools are due to their own attributes. , Is often not available for all teachers.

At present, the laser pointer 5000mw is a very important part of the teaching process for teachers. Teachers can use the laser pointer to indicate the location of the content they are telling. Modern teaching often uses PPT. Teachers will prepare the PPT in advance and then In the demonstration in the classroom, because there are often more points on a page of PPT, in order to facilitate the teacher to tell the students the location of the points when demonstrating the PPT, the teacher will use the laser pointer during the lecture. The laser pointer is generally powered by a battery. It can emit a laser beam when the switch is turned on. After a long time of use, the battery in the laser pointer will be insufficient. It is difficult for people to determine in advance whether the battery in the laser pointer is sufficient. If the laser is in the lecture Insufficient battery in the pen will cause some inconvenience to the lecture.
