After the projector has been working for a certain period of time, its brightness will become lower and lower, and the content projected on the canvas will gradually become unclear, which seriously affects the projection effect. At this time, it means that the life of the projector's lamp has reached its end and the lamp needs to be replaced. However, at present most users will not buy the lamp or replace the lamp, and usually find an official after-sales service or a dedicated projector repair station to solve it. However, if the six-month warranty period is exceeded, the cost of going to the official after-sales replacement projector and lamp replacement is very high, and going to a third-party repair point is very easy to encounter a variety of "pits", which makes many users feel very troubled.
There are many types of projector bulbs on the market, and overall, they can be classified according to the two dimensions of the light source of the bulb and the manufacturer. According to the type of light source, it can be divided into UHP lamp (super energy lamp), UHE lamp, metal halogen lamp and LED bulb. UHP bulb is an ideal cold light source. It belongs to ultra-high pressure mercury bulb. It has a long life. It is generally rated at 6000 hours, the longest is even 12000 hours, and the brightness will not decline significantly after the cumulative working time of 4000 hours. . However, due to the high price, it is generally used in high-end projectors. For example, many projector lamp products under Philips Flag use UHP technology to ensure that the projector has a better imaging effect, a longer life and a more stable lighting performance.
UHE bulbs are also a kind of cold light source. The advantage is that the price is moderate. The brightness is almost not decayed before 4000 hours of use. Therefore, many mainstream price projectors on the market are using this type of bulb; the advantages of metal halogen bulbs are the low price, and the disadvantages Short half-life, generally less than 1000 hours of use, the brightness will be reduced to half of the original, and the heat is very high, the projector heat dissipation system is high, not suitable for long-term projection use; LED bulbs have long life, energy saving and environmental protection, compact , Portable and other advantages.
From the perspective of the type of manufacturer, it can be divided into original bulbs, compatible bulbs produced by third-party manufacturers, and old bulbs or fake brand bulbs. Among them, the original light bulb refers to the product officially launched by the projector manufacturer, with the manufacturer's logo packaging and special lamp holder, which is called "original package". Its quality and service life have been rigorously tested, and the product quality is absolutely guaranteed. Basically, it can reach the average use time stated by the projector manufacturer. But the shortcoming is that due to the increase of channels and profits, the price is generally very high, and the supply is very small, it is difficult to buy. Therefore, the overall price-performance ratio is not high.
