Abstract
An air purification device (), a lighting device and a luminaire are provided. The air purification device comprises an air inlet (), an air outlet (), a photocatalytic volume (), a first solid state light emitter () and a second solid state light emitter (). The air inlet receives an air flow (). The photocatalytic volume comprises a photocatalytic material and the air flow flows through the photocatalytic volume to contact some air with the photocatalytic material. The photocatalytic volume is between the air inlet and the air outlet. The photocatalytic material is a catalyst under the influence of UV light in photoreactions between gasses in the air flow. The first solid state light emitter emits UV light towards the photocatalytic volume. The second solid state light emitter emits deep blue light towards the photocatalytic volume. The deep blue light has a peak wavelength in between (400) nanometer and (450) nanometer.
