Photoreactor assembly

Abstract

The invention provides a photoreactor assembly comprising a reactor, a light source arrangement, and a reflector arrangement; wherein: (a) the light source arrangement comprises a plurality of solid state light sources configured to generate light source radiation selected from one or more of UV radiation, visible radiation, and IR radiation; wherein each solid state light source comprises a light emitting surface; wherein the solid state light sources have shortest heart-to-heart distances (p0); (b) the reactor is configured for hosting a fluid to be treated with the light source radiation; wherein the reactor comprises one or more reactor walls and a light transmissive reactor window; wherein the light transmissive reactor window is configured in a radiation receiving relationship with the solid state light sources, and is transmissive for the light source radiation; (c) the solid state light sources of the light source arrangement are configured at a second distance (h) from the light transmissive reactor window; (d) the reflector arrangement comprises one or more reflectors; wherein the one or more reflectors are selected such that a reflection of the light source radiation under perpendicular irradiation of the one or more reflectors is at least 90%; (e) the one or more reflectors, the light source arrangement, and the light transmissive reactor window form at least part of a light chamber; wherein the one or more reflectors are configured to prevent escape from at least part of the light source radiation from the light chamber; and (f) a shortest third distance (d) between the solid state light sources and the one or more reflectors is selected from the range of 0*p0-5*p0, and the second distance (h) is selected from the range of p0-25*p0.
