Abstract: 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.
