Attaching importance to the Dustproof function of projector

The education industry is the biggest market of the projector, with the advancement of Education informationization, most of the central city or capital city has already procured the multimedia equipment. Schools in remote areas are becoming a new market for the key construction areas of education informatization and the purchase of multimedia teaching equipment. In these areas, many schools in the teaching environment are relatively simple, the use of traditional teaching tools and teaching means more, the acquisition of multi-media teaching equipment has put forward many new conditions. How to guarantee the life of the projector longer, reduce the failure rate in use, what kind of function is suitable for the teaching products to become a new procurement problems, and the projector dust-proof function is more and more attention in remote areas teachers.

The main technology of projector

Projector is a kind of precision electronic products, like digital cameras, it concentrates on mechanical, electronic circuit technology in one, depending on the optical system for imaging. Because of the different projection technology, the projector is now basically divided into two camps, one is based on Epson and Sony 3LCD Products, the other is to get HP, Dell and BenQ, ViewSonic and other support DLP technology. The two technologies have their own characteristics, generally speaking, 3LCD of product application early, mature technology, wide application, and DLP technology product launch time is short, but can do a smaller volume, in the low-end projector application is gradually increasing.

The realistic need of dustproof

No matter what kind of technology of the projector, are designed for the user needs a variety of functions, such as anti-theft function, real-time switch function, and dust-proof function is one of the important design.

The first is the impact of the projector cooling, because the projector in the work to emit a lot of heat, so the general projector for thermal considerations, in the projector's chassis generally have slotted for machine ventilation, high-speed airflow is likely to carry tiny dust particles, these particles are likely to affect the LCD panel, At the same time the work of the projector electrostatic can also absorb the small dust particles, which will have an impact on the projection screen, which affects the actual projection effect.

In addition, is the impact of the environment, on the one hand, due to many areas of our country generally many dust weather, so the projector in the use of the process is inevitable dust. On the other hand, the education industry's use of the environment, especially some poor facilities in the classroom and teaching process of chalk ash, will increase the use of the projector dust into the process.

If the user dust can not be cleaned in time, causing the vent obstruction, it may make the projector internal components burned, at the same time, a large number of dust will also affect the LCD screen imaging effect, so that the projection effect greatly reduced, affecting the teaching effect. If the projector has a dust-proof design, it can significantly reduce the failure rate, and extend the working life of the projector.

Characteristics of Dustproof Projector

Dust-proof function In fact has long been the concern of manufacturers, manufacturers have also introduced a number of dust-proof design of the projector products. However, due to the differences in design ideas, the projector dust-proof design methods are also distinguished. For example, Panasonic PT-PS5650 used a fully sealed dustproof device, facing the external channel only exhaust holes and air intake two uses a double dust filter. Sharp's latest products use its second generation of dust-proof technology, the core of the optical engine with a fully sealed metal structure, while the use of the free extraction of the air filter network.

Epson's latest emp-6100/6000 projector has a humanized dust-proof function, and can be operated at a temperature of 40 degrees. It uses a dustproof smoke-proof device, and in the air filter to increase the design of the fold, in the electrostatic action of the small dust and dust particles to enhance the adsorption capacity. To the time, the projector of all the connections for the full seal design, better prevent the entry of pollutants. Because only through the filtered clean air can enter the projector inside, the projector cooling, therefore, even if the projector in the harsh environment to use, can still maintain the interior of the cleaning, to prevent the projector such as brightness decline, such as a series of problems. The concern is that because of its air filter has wind speed sensors, can monitor the flow of air into the projector, when the air filter is blocked, wind speed sensors can be alerted to timely cleaning or replacement of air filters, and air filters using a removable way, the replacement is very simple.

Through the seal design of some systems, while improving the cooling system of the wind and wind design, and add more humanized design, the effect of the projector dust is bound to be more and more good. In fact, as long as manufacturers can keep abreast of the needs of users, design products in line with user needs, it must become the projector market leader.
