In the projector market, according to the function of the projector, there are household projectors, business projectors, engineering projectors, teaching projectors, etc. The corresponding projection parameters and configurations of projectors with different functions are different. The projection area requires larger, longer distance, and higher brightness. Generally speaking, it must also support dual-lens mode, and the light source configuration of the engineering projector is also a core factor, which can better adapt to the changing engineering installation environment. It is suitable for media, government and other fields.
Laser projection has always been a core advantage of engineering projectors. It has the advantage of pure light and pure color, and pure color plays a more important role. Therefore, the dual-color laser technology is born. It is different from the single blue laser + fluorescent color wheel. The red and blue lasers combined with the green fluorescent wheel can have a wider color gamut coverage and more outstanding color performance. , Especially in the red that single laser could not express in the past.
At the same time, someone asked, why not use a three-color laser?
In fact, no matter from the consideration of cost factors, or from the aspects of life and brightness, the green laser will greatly drag the other two colors. The continued use of the fluorescent color wheel happens to solve this problem and maintain the overall reliability of the entire light source system. And cost rationality.
Take the dual-lens LDLP projector as an example. This dual-lens engineering projector uses INAX linear polarization technology, high brightness of 3000 lumens, and the service life of the lamp is 30,000 hours in standard mode, and the highlight is 10,000 hours. Coupled with the dual-lens mode of the projector, it can be used in engineering applications to support the requirements of the various parameters of the projector in the environment.
