Improper method of using the projector

As we all know, heat is the deadly killer of projection bulbs, which is why many manufacturers have repeatedly emphasized the heat dissipation effect. After the projector is shut down, it is better to let it cool down for a period of time. Because the closed design of the projector is difficult to dissipate heat automatically, after unplugging the power, the projection fan will stop working immediately. As a result, the large amount of heat generated by the projection lamp after a long time operation will accumulate inside the projector, seriously affecting the lamp and The electrical performance of the internal components can cause the bulb to explode in severe cases. Unplug the power socket or shut it down. The quick shutdown is due to the new cooling system. In order to avoid this phenomenon, we should turn off the projector after use, let the projection fan continue to cool down, and wait until the heat inside the projector is dissipated. , The projection fan will automatically stop rotating, and then cut off the power at this time. Of course, a business projector with a quick shutdown function will be better in this regard, but if it is not necessary, don't shut it down immediately. It is best not to use the projector for a long time, because after all, the air-cooling effect is limited, which is why the lamp has a life span. In other words, the fan is not enough to take away all the heat, and long-term heat accumulation will reduce the brightness of the bulb or even burst. Therefore, it is recommended that users generally do not use the projector continuously for more than 4 hours. The switching frequency of the switch is too high. Many electronic components have a 'breakthrough' risk. This is why we try to avoid frequent switching on and off when using the computer. The same bulb is even more 'sweet' and 'expensiveSwitch the machine frequently to avoid frequent current or voltage shocks to the bulb and circuit. When the projector is turned on, although it is inevitable to move and adjust in addition to the fixed installation method during the use of the projector, it is a necessary good habit to handle it gently, because under the working conditions of the projector with full power , The bulb will generate a lot of heat, the high temperature generated by this heat will make the filament in the bulb close to a molten state, which is why the filament uses a variety of high melting point expensive metals. So in this semi-melted state, if the projector is shaken, the impact on the bulb will undoubtedly be the first to bear the brunt, and if the high-temperature filament falls, not only the bulb is turned off, but the bulb may also burst, so avoid Vibration is very important. Use the lens cover to block the projection light. We may take a break while using the projector, but we don’t want to turn off the projector. If we keep the projector on during this period of time, we will feel awkward, so we often use it. The lens cover is blocked, but one thing to note is not to use the lens cover for a long time, so that the heat of the projected light will be blocked at the lens. If it is too long for a long time, it will inevitably cause high temperature damage to the lens and the optical machine.
