浅谈光源在投影系统中的革命

具有多色彩、高亮度以及高分辨显示效果的投影系统已经越来越多地应用于各种显示场所和监控中心。而光源是整个投影光学系统设计的前提,没有光,就没有图像被投射出来。为了解决投影系统中因光源而导致的寿命短、色彩一致性差、系统发热量大以及成本高等问题,有的系统开始采用LED光源代替传统的UHP灯泡作为投影系统中的光源。通过将UHP与LED的构造、原理和特点等进行比较,LED比UHP具有更长寿命、更丰富的色彩及省电等特点,从而得出LED光源必将在投影系统中引起一场新的革命。

The Revolution of Light Source in the Projection System

With multi-color,high brightness and high-resolution projection display systems have been increasingly used in various display areas and the monitoring center.The light source is the projection optical system design premise,no light,no image is projected out.The projection system has many problems caused by light,such as the short life,poor color consistency,large heat and high cost.In order to solve those problems,some systems began to use LED light source instead of the traditional UHP lamp as light sourc...
