    • Optical systems for focused light emission, which can be used as full color-capable pixels in grid assemblies, such as variable message signs and outdoor electronic display boards. The optical systems may include a light source that is a commercially available full-color LED in SMD design having a red, a green, and a blue LED crystal, which may be disposed at an inlet surface of a light-guiding rod having a constant cross-section and a jacket surface made of planes adjacent to each other at sharp edges. The light-guiding rod thereby captures the light substantially completely and completely mixes the different colors and brightnesses efficiently without scattering. The light output of the light-guiding rod lies at the focus of a convergent lens, which focuses the exiting light.
    • 用于聚焦光发射的光学系统,其可以用作网格组件中的全彩色像素,例如可变消息标志和户外电子显示板。 光学系统可以包括光源,其是具有红色,绿色和蓝色LED晶体的SMD设计的市售全色LED,其可以设置在具有恒定的导光棒的入口表面 横截面和由锐利边缘彼此相邻的平面制成的护套表面。 因此,导光杆基本上完全地捕获光,并且不会飞散地有效地将不同的颜色和亮度完全混合。 导光杆的光输出位于会聚透镜的焦点,聚焦透镜聚焦出射光。
