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.

BANFU light shade by thermoplastic acrylic/polycarbonate film.Pervious to light, not easy to break, lightweight, 
saving energy etc. Characteristics. And can design according to customer requirements of different shape and color.
In the market at present most of the light shade adopts acrylic fiber materials, we strongly recommend the use of 
polycarbonate material, this is because:

1, according to German DIN18032 throwing ball test, the impact strength of polycarbonate material for 15 to 20 
times that of ordinary acrylic materials, that is the same thickness is 250 times that of the common glass, have
the effect of the bulletproof.
2, the unique light weight and high strength allows the design with the least amount of material support.
3, ultraviolet resistant layer of polycarbonate material, completely will potentially harmful uv filters out, within the 
scope of the visible spectrum, according to the thickness of the film and color, mask by 88% of the light, 
by preventing the dazzling light, create a comfortable living space.

This series of light shade from the structure of the form can be divided intothree forms:
1, the spherical body: dome spherical, arch type light shade, with multiple elastic sphere structure, impact resistant 
performance is good.
2.Pointed cone: pointed cone type pyramid light shade, angular, ridge, suitable for door head canopy and other occasions.
3, polyhedron: alien structure, according to customer's requirements, modelling beautiful generous.
