Abstract
A LED structure and a method of providing pulsed light energy synchronized with the photosynthesis process by an integrated LED structure. The LED structure comprises a substrate; a plurality of optically independent light emission areas on substrate; a light emitting semiconductor source of a first type mounted in part of the emission area(s); a light emitting semiconductor source of a second type mounted in part of the emission area(s); and wavelength conversion materials of at least two types. The first type is formed on the top of the said first type of light emitting semiconductor sources and the second type is formed on the top of the said second type of light emitting semiconductor sources.The LED structure suits grow light systems that require dynamic luminaires with adjustable spectrum, tunable intensity and controllable pulse mode operation.
