Life span of projection light bulb (how to treat the life span of projection light bulb)

Television has already entered thousands of households, and projector, as a new display device, is still unknown to many people. A projector costs several thousand yuan, and many people will care about its service life.

In general, the service life of the projector is determined by the light source. At present, projector light sources can be divided into three categories: traditional ultra-high pressure mercury lamp, Led and laser light source. The traditional ultra-high pressure mercury lamp can be used for about 3000 hours in normal mode, while the bulb life of LED projector and laser projector is generally more than 30000 hours.

Traditional projectors, that is, projectors using high-pressure mercury lamps as light sources, have a bulb life of 2000-4000 hours. After normal use for more than 2000 hours, the brightness will be weakened, and it needs to be replaced regularly to ensure the image quality. Calculated by using it for 3 hours every day, the cycle is basically about 3 years.

These are the advantages and disadvantages of traditional projection mercury lamps: brightness is dominant, but service life is also a disadvantage.

And intelligent projection, that is, systematic LED or laser light source projectors, mostly use LED bulbs. As the representative of the Betan Projection F3, the service life of this intelligent projector can reach more than 30,000 hours. If you use it for 8 hours every day, you can use it for more than 10 years, and you don't need to change the light source frequently.

Although the display brightness of intelligent projector can't catch up with mercury lamp, its service life is much longer than that of mercury lamp. Since it can be used for so long, can you watch it every day without paying attention to controlling the viewing time?

Obviously not. From the perspective of intelligent projection maintenance, we don't recommend that you use it for too long. Usually you can turn off the projector for 3-4 hours and have a rest. Some intelligent projectors have small cooling holes, which are prone to heating problems. Long-term overheating will not only affect the service life of the projector's internal components, but also cause the lens material to expand when heated, resulting in virtual focus.

Therefore, when you buy a projector, you should not only pay attention to the traditional mercury lamp projector or intelligent projector, but also pay attention to the heat dissipation performance of the machine.

abstract

The service life of the traditional light bulb machine is between 2000 hours and 4000 hours, and the intelligent projector can reach more than 30000 hours. The brightness of intelligent projection is not as high as that of traditional projection, and the service life of traditional projection is not as long as that of intelligent projection. In addition, the maintenance of the projector also needs to pay attention to the heat dissipation performance.
