Light, especially interior light, has hollow light conductor formed by housing with reflective walls bounded at least partly by output coupling device with opposing reflective cover surface

摘要

The light has at least one light conductor (5) with a light output side and surface, one or more lamps (3,4) arranged to couple light into the light conductor and a refractive output coupling device (11) for coupling out of the output surface with a limited output angle. The light conductor(s) is hollow and is established by a housing with reflective walls bounded on one side at least partly by the output coupling device and an opposing cover surface that reflects at least some light back into a hollow chamber (6). The chamber height decreases away from the lamp.
