One, large-screen optical equipment failure and shortened lamp life analysis
1, large-screen optical equipment inlet air inlet filter net not cleaned.
2. The outside cool air cannot completely enter the inside of the machine, directly affecting the internal heat dissipation of large-screen optical devices.
3. Even if the air inlet of large-screen optical equipment can be cleaned in time, due to the heat dissipation of the large-screen optical equipment itself, some dust will be carried in with the air from the air inlet. Over time, large amounts of dust will accumulate inside the large-screen optical equipment. As a result, the speed of the cooling fan of the large-screen optical device is slowed down, which affects the internal heat dissipation of the large-screen optical device.
4. Gathering dust on the optical path, the brightness of the projector is greatly reduced, and the image is blurred, which also affects the heat dissipation of the projector's optical components, causing damage to the optical components (liquid crystal panels, polarizers, etc.).
5. The user does not operate correctly, such as turning off the power of the projector directly after turning off the large-screen optical device.
Second, how to regularly maintain large-screen optical equipment
1. Put large-screen optical devices in an easily ventilated environment to improve the service life of large-screen optical device bulbs.
2. Regularly clean the large-screen optical equipment to improve the brightness and contrast of the large-screen display system (by 10% to 30%).
3. When the air temperature is very low, it will affect the normal use of outdoor large screens, generally below minus 30 degrees Celsius, it is recommended to temporarily stop using. Of course, other measures such as installing air conditioners in the cabinet can also ensure normal use.
4. Pay attention to the maintenance of daily optical components (color wheel, LCD panel, polarizer, lens, etc.) to prevent premature aging.
5. If the DLP Video Wall malfunctions, contact the manufacturer in time.
