Abstract

2. A method is for improving the growth conditions for plants in need of light at a specified target area by exposing the plants to a photosynthetically artificial light from a light source.

• A01G 7/04 - Electric or magnetic treatment of plants for promoting growth
• F21V 21/30 - Pivoted housings or frames
• F21Y 115/10 - Light-emitting diodes [LED]

Abstract

A lighting system (3) for providing photosynthetically stimulating artificial light to a speci-fied target area where such artificial light is needed, said lighting system (3) comprising at least one luminaire (1) with a light source. The luminaire (1) emits photosynthetically stim-ulating light at a narrow beam angle of less than and including 20° (FWHM), the lighting system (3) comprises means for positioning the at least one luminaire at a distance of minimum 20 m from the specified target area measured in a light beam direction, and the luminaire (1) is adapted to illuminate the specified target area with a minimum photosyn-thetic photon flux density of 140 µmol/s/m2. A method for improving the growth conditions for plants in need of light at a specified target area by exposing the plants to a photosyn-thetically artificial light from a light source, is described as well.
