With the rapid development of projection technology, a new generation of projectors came out. It is a led micro projector based on DLP technology. In the current home projector market can be described as the gimmick, sought after by the majority of consumers. But why can it do this? What is its advantage? What are its shortcomings? then, let's watch it together.
Led projector advantages
1, led projection using a led light source, in the luminous efficiency is much higher than the common ultra-high pressure mercury lamp in the market, which also makes it have lower power and smaller heat dissipation.
2, its internal structure can be greatly simplified, the size of the projector can also be a small and small, and even can carry it.
3, the advantages in the color domain also allows it to go far beyond the traditional light source, the color gamut can reach 120% of the NTSC color gamut, while the traditional light source projector can reach 70% or so, the color is more excellent models also Can reach 80%, compared to the advantages of LED light source is quite obvious.
4, in the long life of the bulb is usually only 2000-3000 hours, the longest life can only be up to 6000 hours (ECO mode), and the life of the led projection can theoretically up to 100,000 hours, and the current market on the LED light source The projector also has a light source life of 20,000 to 30,000 hours, which is equivalent to nearly 10 times the life of a conventional light source.
5, LED is superior to traditional light source in luminous efficiency, can realize higher luminous flux under lower power situation.
The disadvantage of led projector
1, relatively low brightness
Even comparing the current low-end projection of the market, the brightness of the LED projection is very low, generally around 150-300 ANSI. Although there are high-brightness LED light sources on the market, it is difficult to use in projectors because of the high cost.
2, poor picture quality
Compared to ordinary projectors, the resolution of the led micro projector is low, with a maximum of 1,280,800, and it is even impossible to reach the minimum standard of 1920, 1080 for home projectors.
3, small projection size
Compared with ordinary home projection maneuvers, the 60-120-inch projected image of the led projector is not enough to be seen, and can only be used in the bedroom.
