In many parts of China, dust has become a source of frustration for lower-floor users. Even in coastal cities, residents of the first and second floors will find a layer of dust on their balconies in a few days. This is especially true if you live in a relatively dry area, where you have to rub it every day to keep it clean. If the projector is used on the lower floor, it is very important to clear the dust.

Projection tips keep this in mind on low floors using projectors

If the dust inside the projector is not cleaned for a long time, it will affect the heat dissipation, which is the same as that needed by the computer mainframe. If the light source inside the projector is a bright light source, it is also possible that the bulb will burst due to long time of dust cleaning and long working time.

Ash accumulation on the color wheel will affect the speed

Home projector products use DLP projection technology, more long time not clear ash leads to attach the dust on the color wheel, not only leads to smaller light transmittance of the color wheel, can also lead to uneven color wheel speed, deterioration in picture colour effect. And some of the 3 LCD projection technology products more attention should be paid to clear ash, because of 3 LCD projectors light path is semi-closed, if dust accumulated on the LCD panel, screen will appear black spots, seriously affecting the user's view this.

Dust accumulation will have a great impact on the performance of the projector, so good dust resistance is quite necessary for the projector. There are many different kinds of dust filter, in the market now for composite materials that are widely used in the mesh type and mountain fold screen, suggested to use, easy to dust collecting user home after long time use them to replace.

Projector air filters are also used in purifiers

And now the projector mall on the dustproof performance of the machine itself is also down, especially on the color wheel, magnetic sensor magnetic induction color wheel using hall effect magnetic field density change to detect the color wheel rotation, not affected by dust, in prevent the respect such as jitter, oil resistant performance. The infrared sensor of color wheel designed with convex shape makes it difficult for dust to fall on the color wheel without accumulating dust.

Magnetic induction color wheel signal reception is not blocked by dust

Although the current home projector product is equipped with a relatively complete anti-dust device when it is purchased, it will still accumulate dust after a long period of use in the dusty land. This requires the user to clean the equipment regularly, change the dust filter network and other work, a short time to clean the dust will ensure a high-quality viewing experience
