How to make lanterns from old cardboard

How to make lanterns from scrap cardboard:

Preparation of materials: old cardboard, scissors, ruler, rice paper, candles.

Operation steps:

1. First completely disassemble a cardboard box, then cut out a certain geometric structure on the box according to your own creativity.

2. Then cut out different geometric patterns on different surfaces, be careful with the knife.

3. Then stick rice paper inside.

4. Glue the box again.

5. String them together with a rope.

6. The simple lantern is finished!

For children, origami games have many advantages. Origami can exercise children's finger flexibility and develop their hands-on and innovative abilities; objects, small animals, vehicles, etc. of everyday life can be transformed into origami images. In doing so, the imaginationchildren's space will also be improved.

For older people, origami games can not only help them use their brains and activate their thinking, thereby achieving full coordination of the trinity of hands, eyes and brain, but can also prevent memory loss in older adults. Some nursing homes use origami games as a therapeutic approach to patient recovery.

“Origami mathematics” derived from the art of origami uses equations to prove that, in theory, any geometric shape can be simulated with origami. Thanks to software-assisted design, origami researchers can now fold more complex shapes than ever before.

Japanese Tetsu Kamiya used a 2 meter by 2 meter square piece of paper to unfold a dragon, with its scales and claws clearly visible. It is said that there is probably noThere are no more than 20 people around the world who have successfully folded this very difficult form of origami.

On the other hand, modern origami is no longer just an art, but has developed into a new science: the mathematics of origami. It has been used in solar panels for satellites, in storage methods for car airbags, and even in the structural design of the Hubble Space Telescope, it was partly aided by the mathematics of origami.

Energy-saving and environmentally friendly, LED lanterns are more energy-saving and environmentally friendly than traditional lanterns, because the principle of The light emission of LEDs is different from that of incandescent lamps. and gas discharge lamps, energy from the LED light source. The conversion efficiency is very high and can theoretically reach 10% of the energy consumption of incand lampscence. Compared with fluorescent lamps, LEDs can also achieve an energy saving effect of 50%. The energy saving effect is obvious, which is undoubtedly of great importance to China, which is facing very serious energy problems. LEDs can also be used with solar cells, which are energy efficient and environmentally friendly.

Long lifespan. Compared to traditional lanterns, LED lanterns have a much longer lifespan. Let's start with appearance. The shell of LED lanterns is usually made of high polymer PET plastic. Fabric or paper products, compared to products such as PET and acrylic, are prone to fading and damage. Let's start with the light source. Under normal circumstances, LEDs are used., its light attenuation can be reduced to 70%, and its rated life is 100 000 hours, thereby reducing the frequency of replacement and other maintenance work.

The light color of LED lanterns is clear, because the light source uses LEDs, because the spectral range of typical LEDs is relatively narrow, unlike incandescent lamps, which have a full spectrum . Therefore, LEDs can be arbitrarily distributed and combined into various LED light source images, which is particularly suitable for decoration and other aspects. LED lanterns are a product that perfectly combines traditional culture and modern technology. The emergence of LED lanterns has solved the shortcomings of traditional lanterns, while retaining traditional cultural elements and adding new functions. Once launched, it became the first choice for outdoor lighting in China.
