In recent years, with the continuous maturity of technology, projectors have been favored by more and more users, and gradually penetrated into commercial, home entertainment and other aspects, but although the projector is gradually entering thousands of households, but for users, After all, this is still a relatively novel thing, most people are a little helpless in the use and maintenance of the product.
The main problem brought by the irregular operation is that the life of the projector is directly reduced and the projection quality is rough. Therefore, the use and maintenance of the projector is a problem that the user must pay attention to immediately, then how is the projector used? Is it scientific use? How to maintain it in peacetime?
The first thing to note is that after the projector is used and turned off, some users will cut off or unplug the power cord immediately in order to save energy. This energy-saving awareness is very worthy of promotion, but the special working mode of the projector is different from other. For IT products, the most taboo for projectors is this.
Because the projector has an automatic protection function, after the projection is turned off, the internal fan will still run automatically. After the temperature of the bulb is lowered to a certain extent, the fan will automatically stop the heat dissipation, which can prevent the damage of the core device of the bulb. However, if the power is forcibly cut off at this time, the fan will stop running and the internal heat will not be dissipated, which will shorten or damage the projector's lamp life and affect the future projection quality.
Although there are already many products on the market equipped with projectors with instant switching function, for the sake of insurance, we are still slightly more cautious. Here, Xiaobian also reminds consumers that it is best to ensure a 2-3 minute interval between each opening and closing, mainly to allow the product to fully dissipate heat, otherwise it will easily cause damage to the internal components of the projector. .
Followed by the projector's bulb, this also needs to be noted, because in the lighting state, the temperature inside the bulb is thousands of degrees Celsius, the filament is in a semi-molten state, therefore, in the boot state, it is strictly prohibited to shake, move the projector to prevent the bulb Burst, filament break. Proper use and careful maintenance of the bulb can effectively extend the life of the bulb, thus reducing the user's cost of use. It is necessary to pay special attention to the fact that the damage caused by the power failure of the machine is one of the most common reasons for the projector's rework. In addition, reducing the number of switching machines is beneficial to the extension of the lamp life.
Finally, good habits and careful care are the secret of long life of the projector. Whether it is for business users or education and home users, in daily use and maintenance, you must pay attention to dust prevention. This is the maintenance of the projector. At the same time, this is especially important for educational users and areas with large dusty areas in the north. Because the projector's LCD panels are generally cooled by a special fan with a flow rate of several tens of liters per minute, the high-speed airflow passes through the filter dust. When the net is exposed, it may be entrained with tiny dust particles. When the liquid crystal panel is imaged, it is easy to generate static electricity and absorb tiny dust particles, which will adversely affect the projection picture.
The projector's casing is generally slotted or open for ventilation, and the air inlet is provided with an air filter that filters dust and contaminants while the projector is in operation. If it is not cleaned in time, it will easily block the projector vent and cause a malfunction. Therefore, professional and effective dust removal for the projector in a timely and regular manner is the best way to maintain the projector.
