    Experimental Study and Analysis on Lighting Performance of Light Pipe With a Conic Concentrator

    • In this paper, a new light-pipe system with a conic concentrator has been designed and made.Through measuring lighting performance of three new systems in three typical weathers in summer, the luminous flux and indoor illumination distribution have been obtained.Comparing with the results of the unchanged light-pipe in summer, it comes to the conclusion that the lighting effects of the new system are better than that of the original system.
