    • The present invention relates to a projection system, and more particularly, to a projection system including an illumination unit. The projection system according to the present invention includes a reflection part divided into a “n” (n is a natural number) number of partial reflection parts having a first focus and a second focus, a light source part having a “n” number of light source groups, wherein each of the light source groups is located at the first focus of the partial reflection parts and outputs light, and a condenser located at the second focus of the partial reflection parts, for condensing light reflected from each of the partial reflection parts. The present invention can provide a projection system with a small size, including an illumination unit that can be miniaturized. The present invention can also provide a projection system with high efficiency, including an illumination unit that can improve efficiency.
    • 投影系统技术领域本发明涉及一种投影系统,更具体地,涉及一种包括照明单元的投影系统。 根据本发明的投影系统包括被分为“n”(n是自然数)的具有第一焦点和第二焦点的部分反射部分的反射部分,具有“n”个数 光源组,其中每个光源组位于部分反射部分的第一焦点处并输出光,以及位于部分反射部分的第二焦点处的聚光器,用于会聚来自每个部分反射的光 部分。 本发明可以提供一种具有小尺寸的投影系统,包括能够小型化的照明单元。 本发明还可以提供一种高效率的投影系统,包括可以提高效率的照明单元。

    • Disclosed are a lens unit and a method of manufacturing the same. The lens unit includes a lens part including a curved region having a predetermined curvature; and a support part including a hole, in which the lens part is installed, and attached to the lens part at a lateral side of the hole. The lens part having the curvature and the support part of the lens unit are formed in separate processes such that the hole is formed in the support part having the strength, and the lens part is formed by filling the hole with the lens part, so that the movement of resin caused by shrinkage of the lens part when the lens part is cured is inhibited, and the support part and the lens part does not form the layered structure, thereby allowing the lens unit to be formed with a thin thickness.
    • 公开了一种透镜单元及其制造方法。 透镜单元包括具有预定曲率的弯曲区域的透镜部分; 以及支撑部,其包括孔,透镜部安装在该孔中,并且在孔的侧面附接到透镜部。 具有透镜单元的曲率的透镜部分和透镜单元的支撑部分分开地形成为具有强度的支撑部分中形成的孔,并且通过用透镜部填充孔来形成透镜部分,使得 当透镜部分被固化时由透镜部分的收缩引起的树脂的移动被抑制,并且支撑部分和透镜部分不形成层状结构,从而允许透镜单元形成为薄的厚度。
