Bad habits in the use of projector

1, readily unplug the power supply socket or shut off cooling
As we all know, the heat is the projection of the bulb of the killer killer, which is why many manufacturers have repeatedly stressed the reasons for the cooling effect. After the projector is turned off, it is best to let it cool for some time. Because of the closed design of projector is difficult to automatic cooling, unplug the power after the projection fan will stop working immediately, a lot of heat so the projection lamp work for a long time after, it will accumulate in the projector, seriously affect the electrical lighting and internal components, the worst case can lead to the explosion of the bulb.
2, fast shutdown from the new cooling system
In order to avoid this phenomenon, we should be in use, first turn off the switch of the projector, so the projection fan to cool the heat inside the projector, wait until after the projection fan will automatically stop running, and then cut off the power supply. Of course, has a fast shutdown function of the business projector in this area will be a little better, but if it is not necessary, or do not immediately shut down.
3, long time using the projector
It is best not to use the projector for a long time, because after all, air-cooled effect is limited, which is why the light bulb is a lifetime of. That is to say the fan is not enough to take all the heat, and the heat accumulation of long time will let the brightness of the bulb decreased even burst. So it is recommended that users use the projector in general not for more than 4 hours in a row.
4, high frequency switch
A lot of electronic components of the switch action "breakdown" danger, which is why we use the computer to avoid frequent switching machine. The same bulb is "charming" expensive ", particularly in support of the projector fast boot, instantly with higher current to achieve shorter preheating time, the risk coefficient of the file, so we use the projector do not frequently switch, avoid the projection lamp and circuit by frequent current or voltage impact.
5, boot vibration projector
Although the use of the process, in addition to fixed, we inevitably move gently, but is a good habit necessary, because in the open under the working conditions of HP projector, projection lamp will produce a lot of heat, the heat generated by high temperature will make the projection of the filament in the bulb is close to the melting the state, which is why the use of a variety of high melting point metal filament expensive reason. So in this semi molten state, if the projector is shocked, is to bear the brunt of the bulb effect, and if the temperature of the filament drop, then not only the lamp flame, may be some bulb crack, so avoid vibration is very important.
6, cover with lens cover projection light
We may rest in the process of using the projector, but they do not want to turn off the projector, and if in this period of time so that the projector has been lit, will feel very uncomfortable, so often used the camera to cover a block, but it should be noted that not long time use a lens cover, the projection light the heat will be blocked in the camera, long time is too long, will cause damage to the lens and optical high temperature.
