dome and the interior building space is a roof penetration 6 or light passage which can be a variety of shapes but is shown for example purposes as a square opening in fig3 within or under the transparent dome 4 the skylight may include a back reflector 8 for redirecting sunlight entering the clear dome 4 from the sky from the general direction of the earth 39 s equator shown by the arrow in fig3 for the northern hemisphere the equator is to the south and some of the sunlight that enters the clear dome 4 from the south will reflect off the back reflector 8 and enter the roof penetration 6 and be delivered into the building below as useful light either directly or after reflecting from the interior surfaces of a reflective light pipe 12 which is an optional component of the present disclosed subject matter more over other ambient environmental light such a street lights moon light other outdoor lighting may also be directed into the light passage as shown in the exemplary embodiment of fig3 the skylight includes an optical device 14 shown as an inverted reflective pyramid 14 however many other shapes are envisioned and disclosed this optical device 14 can accept sunlight from all compass directions also known as different azimuth directions and reflect a portion of that sunlight downward through the roof penetration 6 into the building below the inverted pyramidal reflector 14 either with or without the back reflector 8 improves.
