Abstract
The invention relates to a method and a device for the conducting/distributing air and light, particularly in a building, or the like. The air and light are conducted along the same transport path. That transport path may be a single duct having a light inlet and an air inlet to it and having ports at intervals along the duct, through which ports light may pass and air may pass. An air flow generating fan, or the like, may communicate with the duct for moving air through the port out of the duct or moving air through the port into the duct, or natural air flow past the duct may be used. The light source may be natural or artificial. Mirrors in the duct may be used to control brightness.
