How to make a strong light? How is the laser projector head made?

Heat the bamboo for half an hour, then take it out and dry it in a cool place, but it should not be overly dry or exposed to strong light. Then the rough skin is scraped and the bamboo strips are cut (the desired length depends on the size of the lantern). Then, according to the weaving method, the lamp stand is completed in a cross way, and several circles of bamboo strips should be tied in the middle of the lamp stand on the lamp wall.

Once the lampstand is ready, you can paste the lantern. To paste the lantern, you should first paste cotton gauze, and then paste the cotton paper used in the second layer to make the lantern. To paste cotton gauze, you must first evenly brush the diluted paste on the surface of the skeleton, then attach the cut gauze lightly to the lamp stand, and finally brush it flat with a brush.

At the same time, the pasted paper must also be pasted without seams to be truly pasted. After the pasted lanterns are dried in a cool and ventilated place, they can be painted for the final step. Painted with personal patterns, such as figures, flowers, birds, ladies, etc., and can be written or not depending on the situation.

After the text and pattern are completely dry, a lantern is completed. Specific 123 PracticesPrepare the tools and materials first.

Scissors, utility knives, rulers, double-sided tape, pens and other essential tools. As for the material, I used red and yellow plastic pads to decorate the lamp body, and the lamp itself was made of an octagonal transparent plastic bottle. (However, if there is a film with moderate hardness and high transparency, it can also be replaced, and it is OK to enclose an octagonal prism according to your preferred size.)

2. Make the lamp cover with red plastic. 3.Decorative lamp cover (decorate it to your liking) 4

Make a handle. 5.Make the lower decoration of the lamp body (with Chinese knots) 6

Install a light source. (You can use your favorite color!) A beautiful lotus lantern was made.

Just buy a 500-watt fluorescent lamp

The method of making the light painting is as follows:

1 Clean the outside of a white plastic bottle, and remove the label on the outside and set aside.

2 Remove the offset printing with wind oil.

3 Cut the bottle along the line. Kaigao.

Lanterns, also known as lanterns, lanterns are a kind of traditional folk crafts of the Han nationality that originated in China, in ancient times, its main role is lighting, by paper or silk as the outer skin of the lantern, the skeleton is usually made of bamboo or wooden strips, and a candle or bulb is placed in the middle to become a lighting tool.

Chinese lanterns, famous in ancient and modern times; Zigong Lantern Festival has been famous for a long time. The industrious and intelligent people of Zigong have not only dedicated the unparalleled well salt technology to the world, but also contributed the beautiful lantern technology to mankind.

In the land of China, which has been staring at the Zen ruler and widely distributing the New Year's Lantern Festival for thousands of years, the Zigong Lantern Festival stands out, gathers the style of Chinese lantern culture, and wins the reputation of "the first lamp in the world", making this national historical and cultural city famous all over the world as "the thousand-year-old salt capital", "the hometown of dinosaurs" and "the southern lamp city". The New Year's Lantern Festival in Zigong has a long history and distinctive characteristics.

Since the Tang Dynasty, there has been the custom of lighting lamps in the New Year, and there are "lion lantern market" and "lantern pole festival" in the Qing Dynasty; At the beginning of the 20th century, it gradually formed a festival lantern festival, and there were more activities such as sky lanterns, dragon lanterns, lion lanterns, and flower lanterns. As a result, it has developed into a festival that integrates the local folk customs and folk customs.

According to historical records, in the Tang and Song dynasties, the Zigong area has gradually formed the custom of lighting lanterns in the New Year and putting up lanterns before and after the Lantern Festival. In the Zigong area of the Tang and Song dynasties, when the lanterns were set off and lit during the New Year and the Lantern Festival, folk acrobatics, juggling and other performances were also presented, which won the love of the people who watched the lanterns.

In the second year of Chunxi in the Southern Song Dynasty (1175), the famous patriotic poet Lu You once wrote in the word "Qinyuan Spring" written by him: "A farewell to the Qin Tower, in the blink of an eye in the New Year, and close to the lantern", it can be seen that at that time, the New Year lanterns and lanterns in the Zigong area have been a customary folk activity. Of course, this is not the same as the lantern festival that was born to be formed.

Therefore, the Tang and Song dynasties should be the embryonic period or initial stage of the Zigong Lantern Festival.

The role of the head and tail metal parts is to fix the semiconductor laser and heat the semiconductor laser. The circuit board can be mounted within the volume of the rear metal parts to provide power to the semiconductor laser.

Currently, there are three types of semiconductor lasers: red, blue, and green.

The function of the head and tail metal parts is to fix the laser diode LD and dissipate heat to the laser diode LD. A circuit board can be installed in the volume of the tail metal parts, and the laser diode can be supplied with power supply.

There are currently three types of laser diodes: red, blue and green.

The laser used by the red laser pointer is very fake.

The main function of the collimator is to focus, to focus the light into light.

The function of the head and tail metal parts is to fix the laser diode LD and dissipate heat to the laser diode LD.

A circuit board can be installed in the volume of the metal part of the tail to supply power to the laser diode.

Just adopt!

A piece of plastic with many small dots fired on it may be equivalent to a small convex mirror, but with a large curvature and flat, so the focal length is very far.

Parallel lasers pass through the plastic sheet to form many points of light, which can be used to compose an image.

How laser projectors work:

Using a YAG solid-state laser, a krypton lamp and a stocking ND:YAG crystal rod are used to generate a laser beam, and the lead in the cavity is converted through frequency conversion to form a visible green light.

The galvanometer is controlled by a computer to deflect at high speed, resulting in beautiful text or graphics. The control software includes the fire phoenix software in Germany, the pangolin software in the United States, etc.

Here's how to make a lamp:

Ingredients: a piece of wire, a small light bulb, a battery, some cardboard (for decoration), a pair of scissors, some transparent glue (preferably with transparent glue, of course, you can also use glue), a switch.

Steps: First, get all the tools ready.

First, connect the two wires to the positive and negative poles of the small bulb.

Then cut the transparent glue into two small pieces, and use the transparent glue to fix the other end of the wire to the battery and connect it to the switch.

At this time, you will find that the small bulb has turned on, so now, you have to tear off a piece of transparent glue from it.

Use scissors to cut the cardboard into some shapes and glue them with transparent glue.

At this point, a miniature little electric light is ready.

Precautions: When making, never let the positive and negative ends of the wire touch, otherwise your hands may be burned.

Lamps, lighting supplies, generally refer to appliances that can be illuminated. In ancient times, humans used torches for lighting, and later there were candles and oil lamps. In ancient times, a "candle" was a torch made of flammable materials, and the torch that had been lit was called a candle. The piles of fine grass and branches that are placed on the ground to be lit are called fires, and those that are placed outside the door are called candles, and those that are inside the door are called court fires.

Where there is light, there is human civilization. Tens of thousands of years ago, humans already knew how to use natural fire to protect themselves from the cold, barbecue and light. More than 3,000 years ago, human beings began to use simple lamps to carry fire candles and write the history of civilization.

From rough stone lamps to bronze lamps, ceramic lamps to modern cracked electric lamps, the historical changes of lamps and lanterns have marked the era of profound travel, and at the same time, they are also the epitome of social economy and culture.
