Projector Products

 

A projector is an optical instrument that uses an optical element to magnify the contour of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, or it can be used to measure the surface shape of the through the hole and observe the surface of the part. The projector is especially suitable for measuring complex contours and small workpieces, such as clock parts, stamping parts, electronic components, prototypes, molds, threads, gears and forming tools. It has high inspection efficiency and is easy to use. It is widely used in measuring rooms and production workshops. The instrumentation and watch industry is particularly suitable.

A projector, also known as a projector, is a device that can project images or video onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals.

Projectors are currently widely used in homes, offices, schools and entertainment venues, depending on the way they work, there are different types of CRT, LCD, DLP.

 

Application classification & Environment

 

1, home theater type: its characteristics are brightness around 2000 lumens (the number continues to increase with the development of projection, the contrast is higher), the projected aspect ratio of the screen is 16:9, various video ports Complete, suitable for playing movies and high definition TV, suitable for home users.

2, portable business projector: generally less than 2 kg of the projector is defined as a business portable projector, this weight is comparable to a thin and light notebook. The advantages of the business portable projector are small size, light weight and strong mobility. It is a substitute for traditional slide projectors and large and medium-sized projectors. The combination of thin and light notebooks and business portable projectors is for mobile commerce users. The preferred mix for mobile commercial presentations.

3, education conference projector: generally positioned in school and enterprise applications, using mainstream resolution, brightness is about 2000-3000 lumens, moderate weight, heat and dust do better, suitable for installation and short-distance movement, function The interface is rich, easy to maintain, and the performance and price ratio are relatively high, which is suitable for mass procurement.

 

4, mainstream engineering projector: Compared with the mainstream ordinary projector, the project projector has a larger projection area, a longer distance, a higher brightness, and generally supports a multi-bulb mode, which can better cope with large-scale The ever-changing installation environment is suitable for education, media and government.

 

5, professional theater projector: This type of projector pays more attention to stability, emphasizes low failure rate, its heat dissipation performance, network function, ease of use and other projectors are very strong. Of course, in order to adapt to various professional applications, the main feature of the camera is its high brightness, its brightness is generally above 5000 lumens, and the higher can exceed 10,000 lumens. Due to its size and weight, it is often used in special applications such as theaters, museums, town halls, public areas, and in environments such as traffic monitoring, public security command centers, fire and air traffic control centers.

 

6. Measuring projector: This type of projector is different from the above types of projectors. In the early days, it was called a contour projector. With the popularity of the grating scale, the projector is equipped with a high-precision grating scale, which is also called a measuring projector. Or projectors, in order to distinguish them from traditional projectors, such projectors are called measuring projectors. Its function is mainly to form an enlarged projector through the transmission of light of the product parts, and then determine the size of the product by using a standard film or a grating ruler or the like. Due to the development of industrialization, this measuring projector has become one of the most commonly used testing instruments in the manufacturing industry. The projection method is divided into a vertical projector and a horizontal projector. According to the standard of its comparison, it is divided into a contour projector and a digital projector.

 

7, mini projection: the so-called mini projector is also known as micro projection, TRT-Lcos portable projector. Mainly through the 3M LCOS RGB three-color projector and 720P chip decoding technology, the traditional large-scale projector is compact, portable, miniaturized, entertaining and practical, making the projection technology closer to life and entertainment. Usually, there are certain rules for the projector in two aspects: a). Size: The usual size is the size of the phone. b). Battery life: requires at least 1-2 hours or more of battery life without power. In addition, its general weight will not exceed 0.2Kg, and some even do not need fan cooling or ultra-small silent fan cooling. It can be carried around (can be placed in a pocket) and the screen can be projected to 40-50 inches or more.

 

8, projector tablet: 2 in 1 projector tablet PC, the tablet PC with projection function. Tablet projector is 60lumens projector tablet PC. That also can be home appliance bedroom protector alike home cinema. With its holder, the images and videos can be projected with a perfect projection of the white wall.
