Abstract (en)

The method employs a horizontal channel (6) opening on to the facade (1) of the building from the ceiling (5) of a room (3). The end (7) of the channel is angled to admit sunlight (T) in quantity adjustable by means of a mirror flap (9). Fresh air (10) enters through an underlying right-angled vent (11) with a throttle flap (12). The other end (13) of the channel receives air from a ventilator (15) and conditioner (16) via another flap (17). The air flows over e.g. a high-pressure discharge lamp (18) with a reflector (19). Mixtures of air and light enter the room through a number of openings (20) preferably having transparent glass plates coated with prismatic film.
