Many consumers are confused about the brightness parameters of the mini hd led projector when purchasing a projector. Perhaps in the eyes of laymen, evaluating the brightness of a projector can only be judged by the value. And as people gradually increase their expectations for high brightness and high resolution, many manufacturers will choose to use the concept of stealth to change the parameters in order to attract attention.
However, in fact, there is not an absolute positive relationship between the effect shown on the screen and the number of lumens marked. Not a projector with a higher lumen is better. So what exactly does a projector lumen do? Let's take a look at the mystery of lumens and learn to say no to false parameters.
Generally speaking, the lumen of a projector is divided into several units. There are only two of them in our daily life, one is the brightness of the light source, and the other is ANSI lumens.
The brightness of the light source refers to the "most original light-emitting brightness level" provided by the laser, light bulb, and LED light in the projector. In simple terms, the brightness of the light source is the brightness that has not been cut by the lens or other factors.
Another type, ANSI lumens is the international standard unit of 2500 lumens projector recognized by the world.
ANSI lumens is the brightness after layer after layer of reduction. Use the sun as a metaphor. The sun itself is the brightness of the light source, and the sunlight shining on us is the brightness that the projector projects on the wall after being cut. The brightness projected onto the wall is ANSI lumens.
According to relevant calculations, the light source brightness of 3500 is approximately equal to 1000-1200 ANSI lumens. Therefore, be sure to look for ANSI lumens when choosing a projector.
There may be consumers wondering what is the relationship between the level of lumens and the size and clarity of the picture?
As the brightness of the projector (lumens is the unit of brightness) increases, the picture projected at the same screen size will become brighter. So it looks clearer, but the resolution does not change; the increase in lumen has nothing to do with the screen size, but the brightness will change as the screen size changes. For example, the screen size is larger and the brightness is lower.
According to the size of the indoor space, in the space of 15-30 square meters, 100-800 ANSI lumens is recommended. In the space of 35-50㎡, it is recommended to be between 1500-2000 ANSI lumens. In the space of 60-100㎡, it is recommended to be between 3000-4000 ANSI lumens. In the space of 120-200 square meters, 4000 ANSI lumens or more is recommended. The two are well understood, because the lumen is proportional to the area of the house.
Politeness in Speech
There are many sweet words and love terms between couples, but try not to say them in front of the parents of the older generation. In that way, they will feel frivolous in front of their parents. In the formal contact process, you should be polite and show your heart in earnest and sincerity.
Maintaining a Smile is the Most Important
Smile is the least polite thing. If you want to make a good impression on male parents, first of all, you need to have a good conversation process. First, you can think: when someone is talking to you, what attitude do you want them to adopt? Usually, looking at the other person is the most important thing. This will make the other person feel that you are really listening attentively, while keeping a smile and a slightly raised corner of the mouth can reduce the relative tightness of the four eyes.
Eyes are wide and ears are everywhere.
The success in advance is equal to half of meeting parents'success, and the other half depends on your own control on the spot. I particularly agree with the saying that the mother is your biggest rival. All mothers have a question in their hearts when they meet their son's girlfriend. Can she be good to my son? So, all you do is to surround this sentence and tell his mother with actions and words that you can.
Etiquette to be noticed in chatting
1. The other party will certainly praise his son in every way. At this time, you will nod your head with a smile, nod at the right time, and follow the words with all kinds of bright and dark boasts. Be sure to laugh. It's a super plus.
2. Male's mother will say their husband and family. My skill is not very good. I can't fully analyze how to deal with it in many cases, but this situation always tells you that their family is very harmonious. They also quarreled and there was a bad time when the two were inclusive. The subtext is to tell you some truth about life and marriage. You must say in time that Auntie is right, I think so. I should learn from you. In this time, you must say it in a timely and sincere manner.
3. Ask about you and your family. This is different from person to person, not deliberately deceiving, but also picks it up, not saying that everything is true. Let's leave a little more topic. There's a long way to go.
In terms of dress, you should try your best to choose light purple quinceanera dresses or white satin dress short,it makes you look very decent.

Although now we have entered the digital era, and e-books are gradually popular and popular, many organizations and individuals think it is necessary to convert paper materials into electronic documents for preservation.
According to media reports, Dai Nippon printing announced yesterday that it had launched the world's fastest 3D book scanner developed in collaboration with professors Masatoshi Ishikawa and Yoshihiro Watanabe of the University of Tokyo. The ocr book scanner scans up to 250 pages per minute at an amazing speed.
As we all know, the speed of general scanning products is not very fast. Among the all-in-one products we tested, the product with the fastest scanning function also takes more than 10 seconds to scan a piece of A4 paper. Then the number of pages scanned per minute is 6. Compared with this high-speed scanner, it's snail speed.
This multi page scanner is different from the traditional one. When scanning, it turns pages at high speed through a mechanical device, takes 3D pictures of pages through two powerful cameras, and uses real-time stereo image identification technology and high-speed aberration correction algorithm to realize fast and high-quality book scanning. In addition, the book scanner overcomes the disadvantage that the traditional scanner must open the book and lay it flat, without disassembling the book.
According to reports, in order to achieve the best printing state, the device has built-in software, which can scan and analyze, correct errors and synthesize two pictures. Finally, it can scan the pictures with the output pixel of 400 PPI, and convert the high-quality output results into e-books, PDF and other formats
iCODIS Megascan X9 scanner could also deliver promising results with its high-pofile performace.

The liner cementing is realized by the liner hanger, which reduces the casing weight of the first well in the deep well, improves the load of the rig lifting system when the casing is cut, and reduces the flow resistance of the cement slurry, which is beneficial to safe construction. Through the liner connection, the problem of drilling operation due to the wear of the upper casing can be solved; using the liner suspension cementing technology can also reduce the amount of casing and save the drilling cost.
Features of Liner Hanger:
The liner hanger drilling is mechanical set by right-hand rotation. Do not use ball and operation easy.
The main parts of the line hanger are made of high-strength alloy steel, which ensures high mechanical performance and strong ability to hang heavy liner.
All of the pump-down plug, liner wiper plug and the landing collar have locking systems and are easily drillable.
The pack-off bushing can be pulled out with the setting tool and therefore saves time for drilling out.
The seal assembly contains a set of "W" packing rings that have perfect two-direction sealing capacity.
To release the setting tool from the liner, simply apply 5 to 10 t load to the drill string and rotate right hand.
The gage rings on the liner hanger not only serve as rigid centralizers, but also protect the hydraulic cylinder and slips while running in.
Applications of Liner Hanger:
The Liner hanger mainly realizes tail pipe suspension through hydraulic transmission. It is widely used in oil and gas wells, technical tail pipe of salt brine wells and geothermal wells and production tail pipe cementing. In the following cases, the tail pipe hanger is used for cementing:

ASTM A795 Steel Pipe
ASTM A795 is the standard for black and hot-dipped zinc-coated (galvanized) and welded steel pipes designed for fire protection specification by the American Society for Testing and Materials. This type of piping is suitable for mechanical and pressure applications as well as for the general use of steam, water, air and gas piping.
About ASTM A795 Steel Pipe's Diameter
Although the A795 pipe can be bent, it is not at ambient temperature, because the inside diameter of the elbow is less than 12 times the outside diameter of the elbow. The ASTM A795 Pipe shall require to the specified chemical composition. Every section of pipe should be hydraulically tested and no leakage through the wall. As a choice of the hydrostatic test, each pipe shall be tested by non-destructive electrical method if accepted by the buyer. Finally, according to the requirements of resistance welded pipe and furnace welded pipe, the ASTM A795 Steel Pipe is compressed.
Most users will pay attention to the performance of the hd mobile projector in color when they purchase the projector. When you buy a hd dlp projector, you need to pay attention to several key parameters, such as brightness, resolution and contrast. These parameters largely determine the image performance ability of the projector. However, many friends realized that although the parameters of different brands of projectors are basically the same, most of them are quite different in color performance. So what influences the color of the projector?
First, the problem of light sources. Light bulbs are used in traditional projectors. The principle of light source of bulb is to electrify the bulb filled with rare gas, which can ionize the rare gas and generate visible light by high voltage discharge. This kind of high intensity gas discharge light source is not pure. There are a lot of messy light, which affects the color of the projection picture.
The impure light from the traditional light source affects the color performance of the projector.
Now there are many monochromatic light sources on the market. The principle is to mix the blue light source (LED or laser) with the Fluorescent Pink wheel to form "white light". But the performance of this white light is not as good as that of the three primary color light source. In addition, in order to improve performance, there are also two-color light sources, such as red laser plus blue laser. The color effect is much better than monochrome light source. Generally speaking, tricolor light source is the best, but the cost of monochromatic and bicolor light source is low.
With different color wheel structures, the color effect of projection image is different
Second, the problem of color wheel. Now, six segment color wheels are mostly used in the projectors on the market. Compared with the early three segment color wheel, the image color will be better. Although different projector products all adopt six segment color wheel, the color of the remaining three segment color wheel is different except RGB three segment. For example, some projectors add white segments to RGB tricolor wheel in order to improve the brightness of projection picture. In order to present a better color effect, some projectors use rgbrgb cycle color segment. What's more, the proportion of each color segment on the color wheel of different projector products is also different, and the image color presented when using is also different.
Adjustment method of color temperature and the brightness of the light source affects the color of the projector
Third, the adjustment of the projector's later software, such as the adjustment of color temperature and color accuracy. The color temperature of the projector is generally 6500k, because such a color temperature will not make the screen have too much color trend. If it is lower than 6500k, the color of the screen will be warmer, otherwise the screen will be cooler. In fact, the brightness of a projector light source has a great impact on the later adjustment of color temperature of the projector. The higher the brightness, the larger and more flexible the adjustable range of color temperature. For example, for the projector with traditional light source, it is easy to adjust the color temperature to 6500k for a brightness of 3000 lumens; for the projector with LED light source with lower brightness, the maximum brightness is 1000 lumens. For the effect of the picture, the color temperature usually reaches 890k or even higher.
