If the ordinary projector is turned off in an abnormal way, the internal components of the projector are easily damaged. This is because the projector emits a lot of heat during its operation. In order to expel this heat in time, the inside of the projector A cooling fan is usually installed. Even if the projector has stopped working, the cooling fan will continue to work until the internal heat is fully dissipated, so that the safety of the optical or electrical components inside the projector will be guaranteed.
The life of the projector will be extended; on the contrary, if the power is disconnected immediately when the projector stops working, the fan inside the projector will stop working immediately, so that the large amount of heat generated during the projection process will be lost. When it is distributed in time, the life of the internal components of the projector will be greatly shortened, and may even be damaged in an instant.
However, some new projector products now use a special power-off protection technology, so that even if the projector is disconnected from the power supply, the internal cooling fan can still continue to cool the optical or electrical components inside the projector. In the future, you can disconnect the power supply immediately after the projector stops working, so as to shorten the power supply time, and also avoid your long wait.
