一种lcd微型投影仪

LCD minisize projector

Abstract

本发明公开了一种LCD微型投影仪,它包括壳体、LCD、投影镜组,它的技术要点在于还包括LED光源、聚光镜组,壳体中依次设有垂直主光轴的LED光源、用于将光源光线会聚并照到LCD的聚光镜组、LCD、用于将穿过LCD光线投影出去的投影镜组,所述的聚光镜组、LCD、投影镜组隔开一定的距离设置。本发明的目的是为了克服现有LCD微型投影仪光能利用率不高、体积大的不足而提供的一种光能利用率高、体积小的LCD微型投影仪。
The invention discloses an LCD minisize projector, which comprises a shell, an LCD and a projection lens group. The technical key point is that the LCD minisize projector also comprises an LED light source and a collecting lens group, wherein the shell is provided with the LED light source vertical to a primary optical axis, the collecting lens group for collecting the light rays from the light source and irradiating the light rays to the LCD, the LCD, and the projection lens group for projecting the light rays passing through the LCD in turn; and the collecting lens group, the LCD and the projection lens group are arranged at certain intervals. Aiming to overcome the defects that the prior LCD minisize projector has low utilization rate of luminous energy and large volume, the invention provides the LCD minisize projector with high utilization rate of luminous energy and small volume.
