What is it about?
This work focuses on the performance evaluation of specifically designed parabolic-profile collector that redirects the low altitude incident rays of the sun efficiently into a mirror light pipe. The collector is able to retrieve substantial light levels in the morning/ evening hours and effective light control at midday.

Why is it important?
With the rise of renewable energy systems, there is an increased demand for improved designs of daylighting devices that work without any external energy source to illuminate the deep dark spaces of buildings. Most of the present designs deliver only low light levels especially during the early morning and late evening. This work focuses on the performance evaluation of specifically designed parabolic-profile collector that redirects the low altitude incident rays of the sun efficiently into a mirror light pipe and thus enhances the lighting to desired levels in the deep dark spaces of the building.
