Compared with the prior art, the invention has the following beneficial effects:

firstly, through setting up the lighting mechanism, when the light source subassembly is the pointolite, wherein, rotate the second carousel, when making the adaptation of light trap and empty mounting groove wherein, the light of pointolite can see through the light trap and become circular shape light scope on the outer wall of exhibition wall body, just can adjust the size of light scope through adjusting the distance of second mounting panel apart from the pointolite, thereby can adjust the size of light scope according to the size of exhibition article, thereby adjust the scope of light and shade, generally, the light of painting and calligraphy exhibition room is darker, directly enlarge the contrast light on the exhibition article, this kind of formation has obvious light and shade contrast, and the light shadow effect that produces has fine setting effect.

Wherein, when rotating the second carousel, make baffler and light trap cooperate, can make the second mounting panel seal by the baffler to the light that makes the pointolite transmission can not shine and go out to the outer wall, thereby stops to form the effect of light and shade contrast.

When the light source subassembly is parallel light source, wherein, rotate the second carousel, make convex lens or concave lens and light trap carry out the intercommunication cooperation, when parallel light passed convex lens or concave lens, can make parallel light output for diffusion and or focus to change the output form of light, when adjusting the position of convex lens or concave lens, the position of focus or the scope of diffusion can be changed equally.

Therefore, through the cooperation of the light source, the illumination range and the focusing degree can be adjusted according to the requirements of workers, so that the multifunctional display painting and calligraphy device can adapt to different display paintings and calligraphy.

According to the invention, by adjusting the position of the second mounting plate, when the light source assembly is a point light source, the blocking plate can be formed to seal the light holes by rotating the second turntable, when the second mounting plate approaches the light source assembly, the second mounting plate can cross the flat section and enter the outward extending section, so that the second mounting plate can be free from sealing the flat section of the mounting box, the whole interior of the mounting box is opened, a gap can be formed between the second mounting plate and the outward extending section, light emitted by the point light source can irradiate towards the light reflecting coating of the second mounting plate, multiple reflections can be carried out in the interior, and accordingly, the weakened light can irradiate towards the direction of the exhibition wall through the gap, diffused illumination is formed, the illumination is mild, and the dazzling sense is reduced.

Through the matching of the transmission rod and the adjusting cylinder, when the adjusting cylinder performs input and output, the angle of the installation box can be controlled to change, so that the output direction of the light hole can be changed, the angle of light can be changed, different irradiation modes and the matching of different angles of directions can be generated, better debugging can be achieved, and meanwhile, the position of a fulcrum can be adjusted through the sliding of the electric sliding block, so that the angle of the installation box can be adjusted more accurately.

By arranging the reflecting plate, after the angle adjustment is finished, the collected light or the diffused light emitted by the installation box can be output to the bottom of the reflecting plate and then reflected to the exhibition on the exhibition wall, which is indirect illumination, so that the dazzling feeling caused by direct illumination is avoided, the incident angle of the illumination light to the exhibition can be changed, and the dazzling feeling caused by direct illumination is also avoided.
