Day lighting

Energy is precious. With out energy we can not think of our world. Energy efficiency procedures are very important. More importantly saving one unit of energy stops the release of 4 kg of carbon dioxide from thermal power plant.

Today we are utilizing Indoor artificial lighting by consuming power. Although we have a big source of light "The sun" in morning we are neglecting that free energy. By utilizing solar energy we can replace artificial light sources thus by saving power.

How can we utilize solar energy. In this article iam going to discuss one path.

By using light pipe we can able to bring Sun light in to indoor environments. It has a dome which collects sunlight and a hollow transparent pipe which transmits light  and a diffuser. Main advantage of light pipe is it can bring daylight in to deep interior spaces.
