Abstract
A lighting system is provided comprising a plurality of LED light sources in heat conductive contact with an aqueous cooling liquid. The lighting system comprises a means for inhibiting algae growth in the aqueous cooling liquid. The lighting system is particularly suitable for lighting a greenhouse. The cooling liquid keeps the surface temperature of the LED light sources low enough to allow them to be positioned close to the plants being grown in the greenhouse, thus providing considerable space savings.
