The projector shown is a portable smart LED projector, often identified as the HY300 model. It works by using a modern LED light source to project images from built-in smart software or external devices. [1, 2]
Core Technology
Light Generation: An LED array generates intense illumination, which is more energy-efficient and longer-lasting than traditional lamps, often rated for up to 50,000 hours.
The projector uses an LCD imaging chip that acts like a tiny screen, modulating light to create the picture.
Projection Lens: A "Highlight Coating Lens" magnifies and focuses this modulated light onto a wall or screen. [1, 2,
Built-in Smart System: It typically runs on Android TV (versions 11 or 12)
