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.

Abstract: The invention relates to a lighting device, to the use of the lighting device in a photochemical reaction, to a photochemical reactor and to a method used by the lighting device. The lighting device 100 comprises an LED unit 110 configured to emit light 114 to be used in the photochemical reaction, a housing 120 configured to house the LED unit, wherein at least a part of the housing is transparent for light to be used in the photochemical reaction, wherein the housing is configured to contain a dielectric liquid transparent for light generated by the LED unit such that it is in direct contact with at least a part of the light emitting side of the LED unit, and a liquid movement arrangement 130 configured to support a movement of the dielectric liquid such that the dielectric liquid transports heat produced by the LED unit away from the LED unit.
