METHOD FOR PROVIDING LIGHT FOR PLANT AGRICULTURE AND LIGHTING DEVICE FOR LIGHTING FOR PLANT CROPS

摘要

1. The method of providing light (511) for crop production of a crop (1) in a crop environment, the method comprising side lighting of a crop (1) with light (511) for crop production from a lighting device (500), the lighting device (500) comprises a grating (530) comprising a two-dimensional arrangement of a plurality of light emitting diodes (LEDs) (510) and a plurality of through holes (570), wherein one or more of the plurality of LEDs (510) are configured to provide said light (511) for astenievodstva and through holes (570) are arranged to reduce the obstruction by the lighting device (500) for a gas and / or flow in crop pollination srede.2. The method according to claim 1, wherein the grating (530) defines the plane (580) of the grating and wherein the LEDs (510) are configured to provide said light (511) for crop production with light beams that have optical axes (581), and wherein the LEDs (510) ) are located so that the indicated optical axes (581) are perpendicular to the indicated plane (580) of the grating. 3. The method of claim 1, wherein the plurality of light emitting diodes (510) comprises two or more subsets (510a, 510b, ...) of LEDs (510), the LEDs (510) of one or more of these subsets being configured to provide light for crop production in the first direction and wherein the LEDs (510) from one or more other subsets are configured to provide light for crop production in a second direction opposite to the first direction. The method of claim 1, wherein the plurality of light emitting diodes (510) comprises two or more independently controlled subsets (510a, 510b, ...) of light emitting diodes (510), wherein two or more of said subsets (
