Buying a projector is an expensive investment, and you need to be very careful about its use and maintenance, because its consumables, such as light bulbs and LCD panels, are not only troublesome but also costly. How to reduce the cost of using the projector later? Can you adopt a precautionary approach to reduce the frequency of problems? If the problem of the projection device is controlled by the user in advance, it is believed that the probability of occurrence of the problem is much smaller, and the cost of the projector is reduced invisibly. The following points are some of the tips on how to use the projectors compiled by the editors. You can refer to them.
Optimally laid out projection environment
When the projector is working, it is greatly affected by the ambient light. If the outdoor light and the indoor light are too strong, the projection effect will be directly deteriorated.
Pay attention to the following points when arranging the projection environment:
1. Place curtains to block outdoor light
2. The light source above or near the screen should be turned off
3. Try not to use reflective materials on walls and floors.
4. Local range illumination, can use spotlight
5. Select the projection screen that matches the environment
For example, everyone knows that the service life of the bulb is certain. In most cases, the life of the bulb is not up to the specified index. Because the internal temperature of the bulb is very high, the ambient temperature control is very important. All projectors have more than one. Fans are used to maintain ambient temperature. When the bulb is in a high temperature environment for a long time, the bulb will accelerate aging and the brightness will be attenuated, causing the bulb to be damaged in advance. A light bulb is currently worth about 4,000 yuan, which is a small expense for each user. If you use 1000 hours, the hourly fee is about 4 yuan. If you use 2000 hours, the hourly fee is about 2 yuan. How to reduce the hourly cost of projection equipment has given us an important topic for research and analysis.
Dust removal
Keeping the internal environment of the projector is an important aspect to improve its service life. Regular optical path dust removal is an economical and practical method. Under normal operating conditions:
1. Through the optical path, the liquid crystal panel, the box filter net, and the dust removal of each component, the ventilation and heat dissipation effect is improved;
2. The ventilation effect is improved, and the life of the bulb, LCD, flying lens head and polarizing plate is improved, and the aging speed is lowered;
3. Eliminate the influence of the dust particles of the circuit board on the working point of the circuit by dust removal, and improve the image quality;
4. Through the improvement of the dust-proof light transmittance, the brightness and contrast of the projector and the color reproduction are improved, and the projection effect is improved.
5. Regularly remove dust once or twice a year, increase the service life of bulbs, LCDs, and polarizing plates, reduce the frequency of replacement, and ultimately save the cost of later use.
6. Regular monthly special person is responsible for cleaning the projector filter, which can reduce the number of times of light path dust.
7. The optical path dust must be operated by professional engineers. Once the positioning of the LCD film is destroyed, it is difficult to recover, so the light path dust removal is risky.
8. Another factor affecting the life of the lamp is the operation problem. The switch projector should be strictly in accordance with the instruction manual. In particular, the power can not be completely cut off at one time, so that the cooling fan can work for a certain period of time (usually the summer working time is longer than the winter). Power or turn off the main power. If the local power outage is frequent, consider using UPS power. (Equipped with indicators, the power can be multiplied by 1.5 times the rated power of the projector, and the delay time is considered for 15 minutes).
