Projector is used more and more widely, not only in some business occasions, but also in many people's home film systems. But most people don't care much about how to use the projector correctly.
In fact, there will be many small problems in the use of the projector. In addition to the basic installation and maintenance, there will be some puzzling occasion in the use of the projector, which will make the user misunderstand the projector. Today, I'll explain the common problems that the projector occasionally has, so that users won't be too flustered in the use process.
The first is about sound.
Many users will be confused about the sound when using the projector. The speaker of the projector is very small. The main function of the projector itself is to show the perfect picture, and the loudspeaker takes up too much internal space, so the loudspeaker design of the projector will be relatively small, so it is better to cooperate with the external sound equipment when using the projector. At present, most of the projectors on the market are equipped with sound output terminals, which is also fully prepared for the external sound equipment.
Secondly, the brightness of the projector.
Many users responded that the projection screen was not as bright as before after the projector was used for a period of time. They asked if there was a quality problem with the projector. Actually not. At present, most projector products use the built-in bulb penetration projection mode, and the projection brightness is mainly determined by the bulb, while the display brightness of the projector's bulb is inversely proportional to its use time. Generally speaking, after 120 hours of use, the brightness of the bulb will drop by 20% - 30%. Therefore, users must pay attention to protecting the projector's bulb in normal use. Do not use it for a long time. Try to turn off the projector when not in use.
Finally, the problem of the picture.
Sometimes the projector has the state that image is unstable state, or the picture blurs and shakes. This is also not a problem with the projector function. Some tips are needed to solve it. First look at the image instability.
The output image of the projector is unstable and has stripe fluctuation, which is mostly due to the inconsistency between the power signal of the signal source and the power signal of the projector. The user needs to plug the power of the projector and the signal source into the same terminal block, which can basically solve this problem.
The condition of blurred and dithering picture. Generally speaking, if the projector is too far away from the signal source, it will weaken signal, and the performance projected on the screen can be blurred or dithered. So when using the projector, it is noted that the distance between the signal source and the projector can not be too large. If the distance between the two is large, it is recommended to use a signal amplifier to help the projector receive the signal from the signal source.

The projection gauze, which is generally not used as a fixing device for performance venues, is a translucent curtain made of thin cotton cloth or chemical fiber with reticulated holes. It is widely used for the holographic projection or gauze projection. Projection gauze as a special screen is most applied for the live holographic 3D digital projection, interactive holograms, and other types of holographic displays.
Gauze holographic screen can be extremely fine barbed wire mesh, can also be not easy to be seen by the naked eyes of meticulous gauze and so on. Different materials and colors also make them different in effect, which based on the effect of the holographic displays.
Analysis on the Application of gauze screen projection Technology in holographic projection
With its characteristics of light transmittance, lightness and high degree of color reduction, gauze screen can be described as a great display in the creative presentation of multimedia dance images, which not only helps dance images to create virtual and realistic visual scenes, but also expands the level of stage space. It strengthens the interaction between the actors and the images in the performance and adds a lot of color to the whole performance.
The application of holographic projection
1. Holographic projection to create virtual realistic scene
Because of the light transmittance of the projection gauze, the transparency of the screen can be changed by adjusting the projection point of the light source to form a secondary imaging, looming actors and images, and form a kind of dreamy virtual scene. Casting light from the front to the gauze can show the image painted on the gauze; when the light is cast from the back of the screen to the gauze, the image drawn in front of the screen appears to cease to exist. To a great extent, it enhances the stage tension of the performance and makes the audience feel the magical world brought about by multimedia dance images.

2. Holographic projection to expand the level of stage space
The light and thin folding of the gauze makes it get rid of the fixed shackles in use, and it can be suspended in front of the stage, in the middle, and so on, and the tilt angle of the gauze can also be determined by the projection angle. The imaging medium composed of gauze can provide a good response of imaging visual effect. Compared with the traditional projection screen, the projection gauze greatly expands the level of stage space.

3. Holographic projection enhances the interactivity of the performance
The audience can see the object on the back of the screen through the gauze, and its light transmittance can be used for secondary imaging, which is more transparent than the traditional projection screen. Gauze projection shortens the distance between the audience and the performer, enhances the interaction between the performer and the audience, integrates the multimedia dance images from the performance into the performance, and makes the performance more complete.

DLP is the abbreviation of "DigitalLightProcessing", i.e. digital light processing. That is to say, the image signal should be processed digitally before the light is projected. It is based on the DigitalMicromirrorDevice (DMD) developed by TI (Texas Instruments) company to display the visual digital information. Specifically, DLP projection technology uses DMD as the main processing element to realize the digital optical processing.
DMD chip is an extremely accurate optical switch device. It can reflect light through micro mirror matrix and form projection, which can digitally modulate light. In DLP orthographic projection system or HDTV, red, green and blue light alternately irradiate the lenses, which are turned on or off according to the video or graphics signal fed into the bottom memory chip. Lenses are switched on and off more than thousands of times a second; the light they reflect passes through the lens and reaches the screen to produce images.
LIn projectors for high brightness applications, three DLP chips are used - green, red and blue, respectively. The light generated by the lamp will be separated into these three colors by the prism, and then directed to the corresponding DLP chip. Then, the reflections of the corresponding pixels on each DLP chip are recombined to generate the image.
The single-chip DMD system used in DLP TV, home theater and small media projector consists of a DMD chip, a light bulb, a color wheel and a projection lens. These devices can well generate sharp and colorful video and images in theaters and some large places. A 3-piece DLP system has more realistic colors and higher brightness. In a 3-chip DLP system, white light is divided into red, green and blue light through prism. These three colors correspond to one DLP chip, and the colored light reflected by each DLP chip will be mixed together to generate a pixel on the screen through the projection lens. DLP cinema system can generate more than 35 trillion colors, bringing unparalleled visual experience.
With DLP technology, commercial projectors, home theater systems, high-definition TVs and large venue projectors can provide incredibly clear and sharp images. It is a digital technology, so DLP projection system can always maintain excellent performance in the service life of the projector, thus bringing unimaginable reliability for display electronic products. Moreover, DLP technology is based on semiconductors, and its lightweight characteristics enable manufacturers to develop smaller, lighter and better products than other technologies. Portable projectors with DLP technology can currently provide 2000 lumens or higher output with a total weight of two pounds.

Picking out the best projector can definitely become a headache for many. People usually think that going to a showroom and browsing projectors at a time can be tiring as you don’t have enough knowledge about the topic. However, you need not worry about anything. Here we present you the ten best ways to pick the right projector for you:
PICK THE PROJECTOR THAT CURBS YOUR REQUIREMENTS
To be precise, there are three kinds of projectors in the market, namely Home Theater Projectors, Business Projectors, and Pico Projectors. Home Theater Projectors usually project wider content and emphasize on image quality and high contrast as they are fit for in-home use. Business Projectors are meant for projecting ppts during Business Meetings and Conferences. On the other hand, we have Pico Projectors that are generally used for gaining portability as you can carry them wherever you go. Make a wise choice as per your requirements.
PICK THE PROJECTOR OF THE RIGHT TYPE
The three most general types of projectors are DLP projectors, LCD projectors, and LCoS projectors. DLP projectors are lightweight and are good for having a smooth projection of video content that can project fast-action scenes with ease. LCD projectors are generally brighter whereas LCoS usually cover everything.
PICK THE PROJECTOR WITH GOOD LIGHT SOURCE
Projectors typically use a standard lamp, laser, or LED for light projection. It is often recommended that you opt for LED projectors instead of ones with a standard lamp. The laser projectors are energy efficient and offer better outputs too, but still LED ones are safer for the eyes.
PICK THE PROJECTOR WITH THE PERFECT ASPECT RATIO
The aspect ratio plays a significant role in achieving the drool-worthy picture quality of a good projector. You may find a lot of attractive projectors in the market. However, very few of them manage to project good quality video content on the big screen. Even though 4:3 projectors are cheaper, 16:9 are better for high picture quality.
PICK THE PROJECTOR WITH THE RIGHT RESOLUTIONS
Yet again, the debate about getting high quality projected video content continues. The resolutions of the projector vary in accordance with the aspect ratio. For 4:3, we have SVGA (800x600) and XGA (1024x768). On the other hand, for 16:9, we have standard HD (1280x720), WXGA (1280x800), and Full HD (1920x1080). 16:9 and Full HD make up for a great combination for achieving high quality projected video content.
PICK THE PROJECTOR WITH THE GOOD BRIGHTNESS
Brightness plays a significant role in the projection of video content. A projector with good brightness can make up for a great video watching experience for the user. Remember that brighter the light, the better the color. The vibrant color won’t impress you unless they are cast in a more colorful frame. Especially for business Projectors, you must have high brightness.
PICK THE PROJECTOR WITH THE REQUIRED CONTRAST RATIO
It is the difference between the darkest and brightest areas of your projected video content. For getting better details out of your projected video content, a good projector must have a defined contrast ratio that can highlight the presence of shadows, in turn, enhancing the picture quality. You’ll know the worth of contrast ratio mostly while projecting video content in darker rooms.
PICK THE PROJECTOR WITH EXCELLENCE THROW RATIO & LENS ZOOM
Throw ratio is critical at times when you are planning to mount the projector right as it decides how much wide image is going to be cast on the screens. In such cases, short-throw projectors are the best as even if the projector is closer to the screen; a wide image will be cast on the screen. The lens zoom avails the user to adjust the size of the screen which can help you out if you have a pico projector in your vicinity.
PICK THE PROJECTOR WITH THE PRODUCTIVE CONNECTIVITY OPTIONS
You might find the need of connecting external devices to your projector now and then. In such cases, you should have the productive ports that can avail you to connect external devices to your projector. Therefore, you must confirm that the projector has important ports such as USB port, HDMI port, VGA port, SD card slot and other ports that should be present for allowing you to connect the devices you own with the projector you’re about to buy.
PICK THE PROJECTOR WITH NICE FEATURES
Features such as Keystone Correction and Lens Shift might help you a lot in enhancing your experience while using a projector. These features will help you in deciding the screen orientation and adjust the image on projectors with ease. In addition to these, you can also opt for projectors that support 3D technology as in the end having a good experience while using your projector is all that actually matters. Wireless projectors and adapters are a good option as well.
This is it for now. Have a fun time choosing the right projector for you!

Brightness is the light intensity that the projector product outputs to the screen, and also the brightness of the projected image. In general, the higher the brightness of the projector, the brighter the image of the same size projected on the screen, and the clearer the image. However, the brightness of the image that our eyes can perceive is not only determined by the brightness of the projector, but also greatly related to the intensity of the ambient light and the size of the image. The stronger the ambient light, the dimmer the brightness of the image perceived by our eyes. Therefore, users must choose the appropriate brightness according to the environmental conditions of their projector. It is not necessarily as bright as possible. In the case of the same other indicators, the higher the brightness is, the higher the price of the projector will be. At the same time, the brightness of the image perceived by our eyes will have a certain range. Beyond this range, the our eyes will feel uncomfortable, especially after watching the image with high brightness for a long time. Our eyes will feel tired and may get hurt to some extent.
It is necessary to remind the user that in addition to choosing the brightness index according to the space size, the user should also consider the lighting conditions of the use environment, screen type and other factors. Under the same brightness, different ambient light conditions and different screen types will produce different display effects. When users choose projector products, they should have a margin for brightness index. Because the brightness of the projector largely depends on the light bulb in the projector, the brightness output of the light bulb will decline with the use time, which will inevitably cause the brightness of the projector to be declined. After 2000 hours of use, the brightness of the projector product decays rapidly, so when users choose the projector product, they must have a comprehensive consideration of the brightness index.
Generally speaking, in the 40-50 square meters of home or reception hall, it is recommended to choose 800-1200 lumens for projector brightness, and 60-72 inches for screen; in the 60-100 square meters of small conference room or standard classroom, it is recommended to choose 1500-2000 lumens for projector brightness, 80-100 inches for screen; in the 120-200 square meters of medium conference room and ladder classroom, it is recommended to choose 2000-3000 lumens for the brightness of the projector, and 120-150 inches for the screen; in large conference rooms or auditoriums with an area of 300 square meters, professional engineering machines with an area of more than 3000 lumens should be selected most projectors, and the screens should be more than 200 inches.

Introduction
Rapid prototyping is an advanced manufacturing technology developed rapidly in recent years. This technology can quickly produce solid parts or models with arbitrary complex shapes from CAD data without any dies, cutters and tools, thus realizing the "die-less manufacturing" of new product development. It greatly shortens the development cycle, reduces costs and improves quality. It can automatically and quickly materialize the idea of ignorance into prototype or directly manufacture parts with certain structure and function, so as to evaluate and modify the product design quickly in response to market demand and improve the competitiveness of enterprises.
Principle of Define Rapid Prototyping Technology
Rapid prototyping is a digital prototyping technology based on discrete stacking forming. It uses discrete/stacking principle (such as solidification, bonding, welding, sintering, polymerization or other chemical reactions) to produce parts. Its working process is to obtain the path, restriction and mode of accumulation by discretization, and to "superimpose" materials to form three-dimensional entities by accumulation. First, in the CAD software system, the chieftain obtains the three-dimensional model plough or the surface data of the part entity through the measuring instrument, and then transforms the model into three-dimensional model. Secondly, the model is processed by data processing, and the CAD model is discretized along a certain direction (usually Z direction), and the plane slice is stratified.
Then the discrete layered information is combined with the information of forming process parameters and converted into the NC code to control the work of the forming machine. A three-dimensional solid part can be obtained by regularly and accurately stacking the materials controlled by a special CAM system.
Typical Rapid Prototyping Process
At present, there are more than ten methods of rapid prototyping technology, such as light curing, laminated manufacturing, laser sintering, fused deposition, mask curing, three-dimensional printing, spraying and so on. Mainstream forming methods are the first four.
Stereo lithography apparatus
Stereo lithography apparatus(SLA) is also known as stereolithography. SLA process is based on the principle of photopolymerization of liquid photosensitive resins. Under the specific wavelength and intensity of ultraviolet light irradiation, the liquid materials rapidly undergo photopolymerization, and the materials change from liquid to solid. The schematic diagram of SLA forming process is shown in Fig. 1 (a). The liquid tank is filled with liquid photosensitive resin. Under the deflection mirror, the laser beam can scan on the liquid surface. Where the light spot is scanned, the liquid solidifies. At the beginning of forming, the depth under the liquid level of the working platform is determined , and the liquid level is always out of the laser focusing plane. After focusing, the spot is scanned point by point on the liquid surface according to the instructions of the computer. It is point by point solidification. When a layer of scanning is completed, the untreated area is still liquid resin. Then the elevator drives the platform down one layer of height, and the formed layer is covered with a layer of resin. The scraper scrapes the liquid surface of the resin with high viscosity, and then scans the next layer. The newly solidified layer is firmly adhered to the former layer. This is repeated until the whole part is manufactured and a three-dimensional solid model is obtained.
Fig. 1 (a) 3.1Stereo lithography apparatus
SLA method is the most widely studied method in the field of RP technology, and it is also the most mature method in technology.
Generally, the thickness of the layer is (0.1-0.15) mm, and the precision of the formed parts is high. Years of research have improved the cross-section scanning mode and resin formability, so that the processing accuracy of the process can reach 0.1 mm, and now the highest accuracy has reached 0.05 mm. However, this method also has its own limitations, such as the need for support, resin shrinkage leading to a decline in accuracy, and photosensitive resin has a certain degree of toxicity, and so on.

The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is in stable and reliable working condition.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
The Working Principle of Ball Mill:
This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by the barrel and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.
Ball mills are widely used in production industries, such as cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and ferrous metals and glass ceramics and others. It can grand things in dry-type and wet-type for all kinds of ore and other grindable materials.
The Structure Characteristics of the Ball Mill
The ball mill consists of feeding parts, discharging parts, rotary parts, transmission parts (reducer, small transmission gear, motor, electronic control) and other main parts. The hollow shaft adopts cast steel, and the inner lining of it can be dismantled. The rotary large gear is machined by casting hobbing process, with a wear-resistant lining plate in the barrel, which has the ability of wear resistance. Our machine runs smoothly and has reliable performance. According to the material and discharge way, we can choose dry-type ball mill or wet-type ball mill.
Quick-wear Parts of the Ball Mill
The quick-wear parts of the industrial grinding mill mainly refer to the lining boards, the wear and usage time of the liner are related to the cost and production effect of the ball mill. Then how to identify the advantages and disadvantages of the lining boards. We can conclude it mainly from three steps, the first to see is the lining plate casting and smelting process, the next step is to check whether the lining plate quenching and tempering treatment are qualified, and at last, we need to look at the lining board material carefully. At present, the common lining materials in the market are high chromium cast iron, low alloy wear-resistant cast steel and high manganese steel material. These three kind of materials of lining boards of the three kinds of have good wear resistance ability. GUIKUANG machinery welcome you to our factory to inspect the production process of ball mills and the lining plate’s manufacturing techniques.
The Operation Principle of the Ball Mill
The material is entered into the hollow shaft by the feeding device, and then it enters the first warehouse of the ball mill evenly. There are stepped lining plates or corrugated lining plates with different sizes of steel balls inside the warehouse. The cylinder rotates to produce centrifugal force for bringing the steel ball to a certain height and then it falls down. This produces heavy blow and grinding effects to the material. After the rough grinding process, the material enters the second warehouse through a single clapboard. The warehouse is lined with a scale-board with steel balls for further grinding. The powder is discharged by the discharging grate plate to finish the grinding operation.
The Classifications of the Ball Mill
According to the different materials processed by the ball mill, GUIKUANG machinery produces the following kinds of ball mill, such as gold ball mill, black manganese ore ball mill, nickel ore ball mill, tin ore ball mill, copper ore ball mill, pomegranate ball mill, andalusite ball mill, aluminum grey ball mill, molybdenum ore ball mill, fluorite ball mill and so on.
Conventional capacitors can only meet the requirements of circuit operation with a simple structure and small load, but it is difficult to store charge for circuit operation with a large load. In recent years, the popularization and application of supercaps have effectively solved the problem of large load circuit operation and ensured the normal performance of power electronic equipment.
Super capacitor advantages
Ultra capacitors are the upgrade of ordinary capacitor devices, and many improvements have been made to the early capacitors. The main advantages are (1) capacitance. The conventional capacitors used in the early stage have small capacitor storage capacity, which can only meet the needs of small load circuit; while the capacitor level of super capacitor can reach farad level, which can meet the needs of more complex circuit operation. (2) Circuit. Ultra capacitor has a low requirement on the circuit structure. It does not need to set up a special charging circuit and control discharge circuit, and the service time of capacitor will not be affected by overcharge and over-discharge. Welding. Common capacitors can not be welded. When Supercapacitor is installed, welding treatment can be carried out according to the need, which prevents the occurrence of bad battery contact and improves the performance of capacitor components.
However, super capacitor is not superior in every aspect of the use process, which requires that the advantages and disadvantages of the device be mastered skillfully when using supercaps. Due to the limitation of manufacturing technology, there are still some shortcomings in installation and debugging when using super capacitor in China. Many devices cause circuit failure because of blindly using ultra caps, which affects the performance of the whole equipment. However, as a new product of capacitors, ultracapacitor has more advantages than disadvantages.
Want to buy cheap supercapacitors? Kamcap provides you with high-quality ultra capacitors. We have different types of super capacitor for sale. Inquiries are always welcomed.
Kamcap is one of supercapacitor manufacturers in China. The company has introduced professional automatic testing equipment such as kamcap supercapacitor, automatic casing machine, laser welding machine. If you want to know disadvantages and advantages of supercapacitor, you can call us.

Material analysis of jewelry and clothing
There are many kinds of clothing materials, and the materials are the most basic material basis for clothing, such as cotton, linen, woolen wool, woolen fabric, and some chemical fiber fabrics. The common characteristics of these materials are that the lines are clear and have a sense of volume, which can form a plump clothing outline. Knowing the materials of clothing can help designers better choose matching jewelry materials in order to achieve a better design effect.
The performance, shape, and plasticity of different clothing materials are different. The glossy material surface is smooth and can reflect light, and the visual effect is strong. Thick and stiff material, whose form of expansion is not suitable for excessive use of pleats and accumulation, otherwise it is easy to produce a heavy sense of beauty. The soft material is light, soft, and strong, such as cotton, silk, and chemical fiber. The transparent material is simple and fashionable and can achieve mysterious and elegant artistic effects, such as lace.
Jewelry materials are also rich and diverse. Firstly, they are metal materials, including precious metal materials such as gold, silver, platinum, palladium, base metal materials such as iron, aluminum, copper, sub-gold, rare gold, and other alloys; The second is gem material, including inorganic gem materials, organic gem materials; In addition, there are some gem imitation products, such as synthetic gems, glass, plastics, etc.;
In addition, due to the pursuit of personality and the diversity of jewelry materials, more and more materials are used by jewelry. Apparel fabrics such as wool, silk fabrics, leather, and lace are also used to make jewelry. The texture and luster of these jewelry materials also have their own characteristics, so when choosing and matching, you should pay attention to the texture and characteristics of jewelry and clothing.
Jewelry and clothing matching design
Material:
When choosing materials, you should choose materials with similar and harmonious textures but not fusion, to prevent jewelry from drowning in clothing and failing to achieve the purpose of decoration. You can also choose materials with distinguishable textures so that clothing and jewelry can play their own highlights and values. For example, when wearing clothing with glossy fabrics, we can choose to wear jewelry with less shiny, such as turquoise and matte metal, so that the gloss of clothing and jewelry can be neutralized to achieve overall harmony.
color:
Color is the most direct message received by the human sensory system, so color is the most important factor to be considered when matching clothing and jewelry. When matching jewelry and clothing colors, the overall color should be harmonious and pleasing. For example, when the overall color of the clothing is darker and dull and monotonous, you can choose bright and changeable jewelry to break the deadlock, so that the overall effect of "revitalization".
Summary
We all say that art comes from life, and jewelry design is no exception. From international brands to niche brands, we appreciate that their works are inspired by nature on which we live, or flowers, birds, gods, and beasts. Without exception, it has become a wonderful tool for jewelry designers.

Ordinary projectors require us to put them in the right place to the screen as far as possible, but the laser projector 1080p does not have this problem. Even if the projector is placed in the corner, the projected picture does not have any distortion. Laser projection does not produce ambiguity anywhere.
In terms of display effect, because laser projector 1080p simulates natural colors, the colors and layers are also more abundant. The wavelength of the light is fixed, so it looks comfortable, without the blinding discomfort of the bulb. More importantly, ultraviolet radiation without traditional light source makes the eyes relax when they look at the picture, which is incomparable with either projection device or active luminescence device.
The lifetime of laser projector 1080p is four times longer than that of a traditional projector.
Disadvantageof laser projector 1080p:
The unit price of laser projector 1080p is higher than that of an LED projector. Although the service life of the laser projector is longer, once the light source is damaged, the cost of laser projector 1080p is higher than that of a traditional projector.
