Inductively powered light engine for spinning disc reactor

A photoreactor assembly comprising (i) a light source arrangement, (ii) a photochemical reactor, and (iii) an induction based electrical power system;

• wherein:
• the light source arrangement comprises one or more light sources, wherein the one or more light sources are configured to generate light source radiation selected from one or more of UV radiation, visible radiation, and IR radiation;
• wherein the light sources comprise solid state light sources;
• the photochemical reactor comprises a reactor chamber configured to host a first fluid to be treated with the light source radiation;
• wherein the reactor chamber is configured in a light-receiving relationship with the one or more light sources;
• the photochemical reactor comprises a spinning disk reactor, wherein the spinning disk reactor comprises a disk at least partly configured in the reaction chamber;
• the induction based electrical power system comprises an electrical power transmitter-receptor pair, which comprises an electrical power transmitter and an electrical power receptor, wherein the electrical power receptor is functionally coupled to the light source arrangement;
• wherein the photoreactor assembly further comprising a rotor and a stator;
• wherein the rotor is functionally coupled to the disk or comprises the disk;
• and
• wherein the light source arrangement and the electrical power receptor are at least partly comprised by the rotor or the stator and sealed from an external environment.
