The light bulb in the projector serves as an internal light source, and its role is to project an image or video onto a curtain or white wall. Imagine that if the light bulb is broken or does not shine, then in the darkness, the human eye cannot see anything. So the light bulb is so important, how long can it be used, how to extend the life of the light bulb?
At present, there are two types of projectors equipped with lamps on the market:
How to extend the service life of the projector bulb
The above is a related share of the life of the projector. Although the lamp of the projector can be used for a long time under normal circumstances, it is always right to take care.
At present, there are two types of projectors equipped with lamps on the market:
① The life of a traditional lamp projector is relatively short, and it can maintain an average of about 2000 to 5000 hours.
② The LED projector is equipped with LED lamp, which has a longer service life. Theoretically, the service life of this type of projector can be as long as more than 20,000 hours, without frequent replacement of the light source lamp;
How to extend the service life of the projector bulb
①Do not moveitat will during the use of the projector, especially when it is vigorously moved: After the machine has been running for a period of time, the bulb will heat up. When the temperature is high, the filament inside the bulb is usually half melt Work in a state, so you must not "crude" the machine at this time, otherwise the light bulb may be scrapped.
②Don'tdirectly cut off the power during use: the projector is generally equipped with two cooling fans (one in and one out). After the power is cut off, the fan will not work because the power cannot be supplied, and the heat generated by the previous work cannot be dissipated in time. Therefore, prolonged exposure of the projection lamp to a high heat state will directly reduce its life.
③Regular breaks: Just like people, the machine will be worn for a long time. It is best to let the projector take a rest every four hours.
The above is a related share of the life of the projector. Although the lamp of the projector can be used for a long time under normal circumstances, it is always right to take care.
