A light unit for illuminating signs has a panel having a first surface and an opposite second surface. A plurality of light pipes of transparent material is integrally formed on one or both surfaces of the panel. Each light pipe has a first end to accommodate a LED, a second narrower end and side surfaces including a bottom surface and a top surface, the top and bottom side surfaces being tapered relative to each other from the first end to the second end. A light source is mounted at the first end of each light pipe such as to direct a beam of light into the light pipe towards the second end of the pipe. Light emitted by the light source may egress on one or both sides of the panel. The unit has an increased light efficiency and a reduced use of material compared to prior art designs.
