n our daily use of the projector, the main concern is the appearance and parameters of the machine, such as the material of the machine, processor, resolution, etc. But few people care about the quality of the light source, which is the type, the brand. In fact, the light source is a major focus of the projector.
The light sources of the projector are mainly divided into two categories: traditional light sources, namely UHP, UHE, halogen light and other high-pressure gas discharge light sources. Emerging light sources, so-called LED light sources, hybrid light sources and laser light sources. Bulb light source metal halogen lamps have low prices and short lifespan, generally between 1800-2200 hours, and after more than 1000 hours of use, the brightness of the bulb is only about 60% of the previous, and has been gradually eliminated. UHE lamp, which is a kind of ultra-high pressure mercury lamp, generally has a service life of about 3500 hours. Because of its short life, its price is relatively popular, and its performance is not superior, it is mostly used in low-end projectors. UHP lamp, life expectancy can reach 8000-12000 hours at 100 / 120W, and there will be no obvious attenuation of brightness after 4000 hours of accumulated working time.
Because of its small size, long life and high brightness, it is mostly used in mid-end and high-end projection products Nowadays, UHP lamps also frequently appear in projection products, and the usage rate also increases frequently. Xenon lamp bulbs have a long life, because of their high performance, they also have requirements for equipment. They have a long life, and are mostly used in the fields of UV-VIS spectroscopy, fluorescence spectroscopy, liquid chromatography, thin film measurement, semiconductor testing, medical analysis and other fields. LED light source, the product body is small, high portability, and simple to use. The brightness is mainly based on the 500 lumen high-definition projector, which is unanimously recognized by users in the market. In terms of application, it can bring great convenience to small businesses and personal entertainment, so it is mostly used in miniature projectors.
The laser light source has large selectivity, good temperature control, high spectral brightness, long service life and high price. Mostly used in more high-end products, such as cinema projectors.
Nowadays, projectors are endless, and the parameters are almost the same, so when we bought the projector, it was a bit dazzling. The author is here to tell you that no matter what the performance of other components is when buying a projector, you must first look at the lens of the projector.
What do we buy a projector for, of course, for the picture, and the focus of the decision is the lens.
The following editor will first talk about why the lens is the first aspect of buying a projector.
From the appearance,
see if it is a closed lens. The closed lens will reduce the entry of dust, because the entry of dust will cause blurry pictures, spots, and difficulty in cooling the machine.
From the parameter
The service life of the light source has time. It is best to know the brand and price of the lens in advance, because long-term use will reduce the quality of the picture. At this time, if you want a good experience, you should change the light source.

From the parameter
1, the color gamut and resolution of the lens light source: this is the most important factor that determines the display effect of the projector.
2. The maximum brightness of the light source: The maximum brightness means whether it can be viewed for a long time, the temperature of the lens rises, etc. If the temperature is too high, the service life will be greatly lost.
The service life of the light source has time. It is best to know the brand and price of the lens in advance, because long-term use will reduce the quality of the picture. At this time, if you want a good experience, you should change the light source.
