RGB Laser projector,4k

The interactive exhibits at the science museum use this 12,000-lumen 3LCD projector. Even on a 300-inch projection wall, the images remain vibrant with no vignetting, and the animations of dynamic exhibits are smooth and ghosting-free. Visitors don't experience eye strain even after prolonged viewing. The most impressive feature is the laser light source. We've been running it for 12 hours a day for over a month without any brightness decay. It's incredibly easy to turn on and off without warm-up, making setup extremely convenient. Initially, we were worried about heat dissipation with such high brightness, but in practice, the projector's temperature remains stable, and the noise level is low, completely unaffected by the explanations or interactive atmosphere of the exhibits.
