A Brief Analysis of Totally Enclosed Dust-free Optical Engine and Open Optical Engine Technology

图片
In recent years, CRE's fully enclosed dust-free optical engine has completely exploded the home LED projector  market, and with its high quality, low after-sales rate and easy customization, major LED projector  brands have chosen CRE's optical engine to enter the home LED projector  market. So, why is a fully enclosed optical engine recognized by the market? What are the advantages of a fully enclosed dust-free design over other types of optical engines?   First of all, we need to have a preliminary understanding of the composition of the optical engine, most of the LED projector s on the market now take the reflection principle of light source → screen → imaging as the design concept. So, a LED projector  imaging brightness and its light source brightness has a direct link, the stronger the light source brightness power, brightness loss in the projection process less, so the final imaging effect will be better, but also, the higher the power of the light sourc...
