Estimating the term…
The invention relates to a lighting device for a photoreactor comprising a tubular housing (40) having a longitudinal axis (41) and a plurality of individual light sources (30) mounted on the inner surface of the housing (40), wherein the housing (40) comprises flow channels (46) for a heat transfer fluid, the flow channels (46) being arranged at the back side of the inner surface of the housing (40) behind the individual light sources forming a conformal cooling passage for the individual light sources. The invention further relates to a photoreactor comprising a lighting device and a reaction chamber with at least one tubular flow channel, the reaction chamber being arranged inside the lighting device and the channel wall being made of a material transmissive to the light emitted by the light sources.

A lighting device for a photoreactor comprising a tubular housing having a longitudinal axis and a plurality of individual light sources mounted on the inner surface of the housing, wherein the housing comprises flow channels for a heat transfer fluid, the flow channels being arranged at the back side of the inner surface of the housing behind the individual light sources forming a conformal cooling passage for the individual light sources, such that the channel walls of the flow channels directed toward the light sources essentially follow the form of the inner surface of the tubular housing in the areas where the light sources are arranged.
