Description
The technical field is as follows:
the invention relates to an LED light-emitting device for students, which has an illumination effect and can shoot an operation process in real time to realize online education
Technical background:
the LED chip has small volume, long service life and high light efficiency, and becomes the main light source of the current operation desk lamp. The lamp using the LED chip as the light source has the characteristics of rich shape, long service life, energy conservation, environmental protection and the like, and is a main lighting tool used by students during the work at present.
The camera is also called a computer camera, an electronic eye and the like, is a video input device, and is widely applied to aspects such as video conferences, telemedicine, real-time detection and the like. With the development of the technology, the size of the camera is smaller and smaller, meanwhile, the resolution is higher and higher, and the close-distance shooting is clear and visible.
The invention provides a technical support for solving the problem that the operation of children is difficult for many parents, the children are busy to work, no time is available, the operation difficulty is high, the operation capacity is low, and if the remote online tutoring operation can be realized, a teacher can tutor a plurality of people for operation simultaneously or parents can tutor the operation while working.
The invention content is as follows:
the invention mainly relates to a light-emitting device with high resolution, which can shoot the work process of students in real time to realize online education.
The technical scheme is as follows:
a light-emitting device for realizing online education comprises a reading-writing desk lamp and a camera;
1, the selected camera is a high-resolution camera; the resolution ratio is more than 300 ten thousand pixels, and each word written by the student can be clearly seen;
2 the selected lens covers the breadth of a student desktop A3, namely the field angle is 60-100 degrees;
3 the light source of the light-emitting device is an LED, and the light source can illuminate the A3 breadth of the student desk top to reach the relevant illumination standard;
4, the shooting area of the camera is a read-write working area;
5, the camera is electrically connected with the LED light source board, shares a power supply with the light source, and is turned off when the light is turned off;
6, the camera is positioned on the light emitting surface of the desk lamp or the lamp cap, the installation angle is adjusted and fixed towards the reading and writing area, preferably, the camera is installed at the middle position of a long strip for a long strip-shaped light source (figure 1), and the camera is installed at one side, close to a student, of a round or oval edge for a round or oval light source (figure 2);
7, the camera can be connected with a mobile phone, a tablet personal computer and other video terminals through wireless wifi or USB and other Internet of things technologies;
8, the preferable software can realize the geometric correction of pictures, and can realize the transmission of local high-definition videos or global photos;
9 the camera can be matched with a mobile phone, a tablet personal computer or other video terminals to guide the students to work, and also can be used for one-to-one network teaching;
10 parents and teachers can look up the specific process of students in homework at any time through mobile phones or other video terminals, and therefore the students can be guided with pertinence.
