technical field

The invention relates to the technical field of scanning ancient books, calligraphy and paintings, in particular to a light source device for non-damaging scanning of ancient books, calligraphy and paintings.

Background technique

Ancient books refer to books that have not been printed with modern printing technology.

Calligraphy and painting refer to ancient Chinese calligraphy and painting, which constitute one of the traditional art categories of the Chinese nation. Although they have different forms, functions and types of art, they are like a pair of twin brothers in the culture of the Chinese nation. There is an inseparable connection of flesh and blood.

However, the existing light source devices used for non-destructive scanning of ancient books, calligraphy and paintings mostly use LED lights as light sources when illuminating ancient books, calligraphy and paintings, and when the LED light source is working, its internal LED driver board will generate a lot of heat , if the heat cannot be discharged in a timely and effective manner, it will cause the LED driver board to be overheated and damaged, and most of the existing LED light sources are integrated, and this setting method is used in the LED inside the LED light source. When the driving board is damaged, it is difficult to quickly disassemble the LED light source, which makes it extremely troublesome for users to replace the LED driving board.

Preferably, a plurality of the filter screens are arranged in parallel inside the heat dissipation holes, and the multiple filter screens are all made of ultra-fine glass fiber paper.

Compared with the prior art, the beneficial effect of the present invention is that the light source device used for non-destructive scanning of ancient books, calligraphy and paintings is provided with heat dissipation holes and filter screens. A large amount of heat can be fully dissipated to avoid damage to the LED driver board caused by excessive temperature, and multiple filters arranged in parallel inside the heat dissipation holes are made of ultra-fine glass fiber paper materials, which can avoid heat dissipation when dissipating heat. Dust enters the LED light source through the heat dissipation holes and causes a short circuit of the LED driver board, thereby increasing the service life of the LED driver board. At the same time, it is equipped with a sealing ring, convex teeth and grooves. The sealing ring can be connected with the grooves through the convex teeth, so that When the user replaces the LED drive board inside the LED light source, the user can drive the sealing ring to rotate through the bottom plate, so that the sealing ring can separate the bottom plate from the lamp holder through the rotation of the convex teeth and grooves, so as to This facilitates the user to quickly and conveniently disassemble the LED light source, thus making it easier to replace the LED driver board.
