elbow angle of skylight for slope roof

Light tube is a high reflection pipe which guide various wavelength rays from sun light, then been reflected several times, finally been transited to any place need light.

High reflectivity aluminum as raw material, transit the natural light from roof to the lower space This material can make sure the high transition and stability of sun light.

The inside of the light well’s reflection can arrive beyond 99%. As the light been reflected several times in the light well, so the higher the light well reflection, the bigger the light power left and the higher the transmit ion efficient which makes the light spread indoor brighter. This square shape light well with strong stability, high reflection, light weight and anti-rust, easy to install, maintain free. Elbow angle is optional.

Style: rigidity tube, 30° 45°elbow angle, 60°90°elbow angle.

Advantage: high stability, high reflectivity, light weight, anti-rust, long life, install simple, maintenance free.

How many efficiency can the BANFU day lighting system bring?

Economical benefit: electric power saving and reduce air condition’s using, 2-3 years you can recover the cost while the using life is about 25 years, no maintenance cost. The dome on roof can self-cleaning by rain water.

Healthy benefit:Scientific studies proves that natural light has better visual effects and phschonogical effect. It can improve the indoor environment and enhance body health.

Environmental peaceful:natural light been spreaded soft and even, no twinkle, no dizzle light, no pollution, and filter harmful rays which helps to protect the human being’s health.

Fashion:good appearance, creat low energy, high comfortable working, living and entertainment environment. It’s perfect cooperation between nature and artificial constructure.
