Home Theater Projector Tips: Several Common Laser Projector Problems Q and A
June 01, 2022
Unlike traditional projection, laser projectors use the most advanced laser light source technology. The laser is a cold light source. During use, the heat is not large and the temperature is low, so the life can exceed 20000. Hours are more than 10 times the life of traditional projectors. Looking at the entire projection market, many projector brands have begun to develop and even launch their own laser projection products. However, not everyone has a deep understanding of laser projection. Here are a few common questions about laser projection. Q: When it comes to projectors, the first thing we think of is brightness. How bright is the laser projector? A: A single projection head can provide 10,000 to 60,000 lumens of brightness. In fact, many systems have a brightness of more than 30,000 lumens, which is the true value that laser projection can achieve. If more light output is required, any laser projection head can use the Duo technology to assemble a second projection head, resulting in a brightness of 120,000 lumens. Q: What are the advantages of the laser projection system architecture? A: The projection head and the illumination source are independent. The big advantage of the laser projection system is that it is easy to upgrade. The laser module can be activated, disabled, added or removed according to the required brightness or primary color. Laser projectors can also be redundant with multiple laser modules. Even if one module fails, the projector can continue to work as long as there are no problems with other modules. Another advantage is that the projection head can be installed away from the laser module and provided in a demanding position. Flexible deployment allows the illumination source to be installed in different locations for easier management of cooling and noise as well as maintenance, while the modular design simplifies projection system transmission. Q: Is the 3D effect projected by the laser projector better? A: The answer is yes. Laser projection effectively boosts brightness and minimizes crosstalk between the eyes, which means that the laser projection system delivers a more natural, immersive and happier 3D viewing experience for any application. Q: What is the spot, how big is the impact on the movie? A: The spot is the visible 激光 in the laser projection, which is the scattering caused by the coherent light reaching the projection screen, which is expressed as unique video noise. The best solution at the moment is to choose the right screen material. In general, low gain screens are better than high gain screens, and screens (for polarized 3D systems) have the worst spot performance.
