    • The present disclosure relates to a multi-tiered lighting system that has a pole and at least two light sources. A first light source is mounted to the pole at a first height, and a second light source is mounted to the pole at a second height that is substantially different than the first height. The first light source is configured to project a first beam of light that primarily lights up a first portion of a target coverage area, and the second light source is configured to project a beam of light that primarily lights up a second portion of the target coverage area, which is different from the first target coverage area. The first beam of light may spill onto the second target area, and the second beam of light may spill onto the first target area.
    • 本公开涉及具有极点和至少两个光源的多层照明系统。 第一光源以第一高度安装到极,并且第二光源以与第一高度基本上不同的第二高度安装到极。 第一光源被配置为投射主要照亮目标覆盖区域的第一部分的第一光束,并且第二光源被配置为投影主光束,其中光束主要点亮目标覆盖区域的第二部分 区域与第一目标覆盖区域不同。 第一光束可能溢出到第二目标区域上,第二光束可能会溢出到第一目标区域上。
