This invention belongs to the field of reaction chamber technology, specifically relating to an ultraviolet optical cavity reaction chamber module for an air treatment device. The cavity body defines an internal chamber and has an inlet opening and an outlet opening, which are arranged in series with an external airflow passage. One or more internal surfaces of the cavity body are reflective surfaces, the shape of which causes the internal geometry of the cavity body to form an optical cavity. This invention allows light emitted from a region inside the cavity to be repeatedly reflected on an elliptical surface, and to be reflected multiple times within the cavity before reaching the inlet or outlet opening. Simultaneously, the geometric discontinuities at the internal seams minimize the impact on overall optical performance. This invention reduces direct exposure to ultraviolet radiation from the outside of the module and converts intercepted photons into an additional air purification mechanism. Furthermore, the photocatalytic layer does not significantly reduce the reflectivity of the main optical cavity walls.
