Abstract
A luminaire is provided. The luminaire comprises a light source for generating a light, an electrical circuitry for driving the light source, and at least one air duct extending from an air inlet to an air outlet. The air ducts comprise walls with a photocatalytic element and are configured such that the air flowing through the at least one air duct can get in contact with the photocatalytic element and participate in a photocatalytic reaction under exposure to the light generated by the light source of the luminaire and/or an external light.
