The following advantages can be achieved by such an arrangement: the whole function of the teaching board is refined, and electronic teaching aids 3-3 such as a multimedia all-in-one machine or an electronic whiteboard and the like achieve the best definition without light interference; the light of the ordinary writing area works normally and is irradiated by a high-quality light source, so that the eyes of teachers and students are protected. The lattice arrangement lighting light source is one of an LED light source, a laser diode light source, an LVD light source, an OLED light source and a solar photovoltaic structure light source. The array layout and the selected light source performance can achieve the following advantages: moderate brightness, uniform illumination, no stroboflash and no blue light, adjustable brightness and eyesight protection.

The master control switch 5 at least comprises a switching button and a brightness adjusting button of the dot matrix arrangement lighting source and a starting and stopping button of the left and right push-pull motor.

Frame 1 is one shot forming aluminium alloy or high strength PVC extrusion molding section bar.

It should be noted that, in this embodiment, the outer edge specification of the push-pull luminous writing board 2 and the electronic teaching aid 3-3 such as the multimedia all-in-one machine or the electronic whiteboard is equal in length and height, and the push-pull luminous writing board 2, the left luminous writing board 3-1, the right luminous writing board 3-2, the socket 4, the left-right push-pull motor 6 and the rail 7 are all embedded and fixed by the frame 1, so as to form a whole body which can be moved, transported and installed.

The push-pull luminous writing board 2, the left luminous writing board 3-1, the right luminous writing board 3-2, the socket 4, the left and right push-pull motors 6 and the track 7 are fixedly connected in an embedded manner, so that the mounting and dismounting are more convenient and the operation is simple, the mounting and dismounting convenience of the teaching board is improved, and the after-sale maintenance is easy and convenient; like this, can reduce the quantity of spare part, make its structure compacter, can also reduce the equipment process, and then simplify the installation and disassembly process of teaching board, simultaneously, still make the structure of teaching board firm, connect stably, be favorable to improving the life of teaching board.

The selection of the illumination light sources of the push-pull light-emitting writing board 2, the left light-emitting writing board 3-1 and the right light-emitting writing board 3-2 in the above embodiments is not limited to this, as long as the characteristics of low heat dissipation, energy saving, comfortable and uniform illumination, dimmable brightness and partition switch of the cold light source are satisfied, and the illumination light sources can be uniformly projected on the light-transmitting, writable and projectable panel in all directions.

In the above embodiment, the electronic teaching aids 3-3 such as the multimedia integrated machine or the electronic whiteboard can be placed in the center of the teaching board or on the left side or the right side of the teaching board, and the push-pull luminous writing board 2 can be used for shielding and protecting at any time.

The push-pull luminous writing board 2 in the above embodiment can be a single piece, or can be two pieces of push-pull type which are opened left and right and closed left and right; the push-pull type large frame can be pushed and pulled in the large frame and can also be extended to be pushed and pulled to the outside of the large frame; the push-pull luminous writing board 2 can be positioned at the front end of the teaching board or can be flush with the left luminous writing board 3-1 and the right luminous writing board 3-2 by changing tracks, and only the push-pull luminous writing board can emit light, push and pull left and right and shield and protect electronic teaching aids 3-3 such as a multimedia all-in-one machine or an electronic whiteboard.

In the above embodiment, the rails 7 (one whole rail for each of the upper, lower, left and right) are fixed in a concealed manner, and are distributed in an upper, lower, left and right structure, and two push-pull rails, namely, an upper push-pull rail and a lower push-pull rail, or pneumatic propulsion or hanging rail traction can be adopted, so long as the push-pull luminous writing board 2 can be pushed and pulled leftwards and rightwards.

In the above embodiment, the left and right pushing and pulling of the push-pull luminous writing board 2 can be completed by the left and right pushing and pulling motor 6, and can also be completed by manual operation, remote control, human body induction and the like, as long as the left and right pushing and pulling stroke of the push-pull luminous writing board 2 can be completed.

The push-pull luminous writing board 2 in the above embodiment can also be used in a page turning mode by changing left-right push-pull, as long as the electronic teaching aids 3-3 such as a multimedia all-in-one machine or an electronic whiteboard can be protected by light emission and shielding.

In the above embodiment, the master control switch 5 may be a master control panel or an individual controlled in a group distribution manner, and may be manually controlled or automatically adjusted by light sensing control, as long as the control of the front push-pull light-emitting writing board 2, the left light-emitting writing board 3-1, the right light-emitting writing board 3-2, the electronic teaching aids 3-3 such as a multimedia integrated machine or an electronic whiteboard, the socket 4, and the left-right push-pull motor 6 is realized.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the present invention in any way.
