The lamp is the key component inside the projector, but also an important consumable of the more "squeamish", if you usually do not pay attention to protection, the service life of the projection bulb will be affected, thus affecting the use of the projector, so the maintenance of the lamp is very critical, Lingying for everyone to summarize a few points in the use of the projector process, easy to cause damage to the lamp habits, to see if you have a "stroke" right?
When the projector light is covered, the projection bulb will generate a lot of heat during use, part of which is taken out of the machine by the fan that comes with the projector, and some of it will be emitted through the lens film, once the lens is covered, the large amount of heat generated by the lamp cannot be dissipated in time, causing damage.
It is recommended that when you do not use the projector temporarily, switch the projector to standby, which can effectively reduce the power consumption of the projector, but also fully dissipate the heat generated during the previous use and prolong the service life of the projection lamp.
When using the projector to move at will, the projection bulb in the work of a large amount of heat will make the internal filament process semi-melting state, if you move the projector at this time, it is likely to cause the filament to break, the entire lamp bulb may also be scrapped.
Therefore, it is recommended that when you need to adjust the projection position, it is best to cut off the power supply of the projector first, ensure that the lamp is not in a working state, and then adjust the projector in place.
When the power is turned off directly, the current mainstream projector brightness is between 1000-2000 ANSI lumens, high brightness directly leads to more heat generated during use, and the projector is generally equipped with two cooling fans, after the power supply is cut off, because it cannot be powered, it will directly lead to the fan can not work, the heat generated by the previous work can not be dissipated in time, and being in a high heat state for a long time will shorten the life of the lamp.
Therefore, after using the projector, first close the software switch in the projector control panel, let the projection bulb stop working first, let the projection fan continue to work for a period of time, and the heat generated during the work is dissipated, and then cut off the power supply after the cooling fan stops working.
The use of non-original power cord, in general, the projector must use a randomly equipped power cord, but in the actual use of the process, many users may use ordinary universal cords because they cannot find the original power cord for a while, and there is no three-wire socket to replace with two lines, while the power socket is not grounded and is also used, such a small action will also bring great harm to the projection bulb.
In order to ensure that the service life of the projection lamp is not affected, first of all, the original power cord needs to be used, remember not to use some inferior power cords, and secondly, use a three-wire socket, and ensure that the socket is reliably grounded to prevent damage to the projection bulb.
