Abstract: A LED structure, a lighting fixture and a method of providing white light illumination. The LED structure comprises a substrate; a light emitting area defined on the substrate as a cavity; a first type of light emitting semiconductor source with bactericidal characteristics mounted in the cavity; a second type of light emitting semiconductor source mounted in the cavity with ability to excite the wavelength conversion material to generate white light; and a wavelength conversion material layer formed on top of the light emitting semiconductor sources. The invention enables disinfection by a lighting source or a luminaire visibly apparent to human as a white light source that is neither harmful to a human nor creates discomfort.

Abstract: An integrated LED structure and a method of adjusting the emission spectrum of an integrated LED structure, for photobiological process is disclosed. The structure comprises a substrate; a plurality of optically isolated and electrically non-independent light emission areas integrated on the substrate; a light emitting semiconductor source of a first type mounted in the emission area(s); a light emitting semiconductor source of a second type mounted in the emission area(s); an electrical circuit layer for connecting the light emitting semiconductor sources in serial fashion for each emission area; and wavelength conversion materials. The emission areas are controlled with a common electrical drive current, and the emission output can be tuned by adjusting the common current value, to enable use of one luminaire for a large variety of biomass growing applications.
