Fixed roof window skylight and tubular skylight for lighting

What is a Tubular Skylight?    How Do Tubular Skylights Work?   

The picture below shows just how the BANFU really works, in all weathers, from early in the morning to the evening, in summer and winter time, and how much efficiency difference you get in comparison with regular skylights. You will notice: no temperature differences, no shadow on the floor or the walls, abundant light throughout the day! The upper lighting dome absorbs the sunshine sufficiently, after been reflected and enhanced by the sun trapper, the natural light was transmitted to the high reflected light well and guided to the diffuser; the diffuser spread the light to any angle of the space.

As a high efficient, simple install, low cost system,BANFU tubular skylight system can install at any place (flat roof, slope roof) like 

Public facility:shopping mall, supermarket, indoor gym, exhibition hall, zoom, museum;

Industrial building: large scale factory, store,

Military facility: aircraft hangar, maintenance base, equipment warehouse, tunnel;

Civil construction: airport terminal, underground waiting hall, parking lots, school, hospital, government office building, restaurant, residential house, hotel, motel, distribution center, agriculture plant center, breeding center etc.
