Abstract
A lighting module for illuminating cultivated crops in indoor farming comprises at least one monolithic efficiency enhancing optical element (EEOE) further comprising: (a) a front portion comprising a spectrum conversion layer; (b) an optically transparent middle body portion having at least one light source embedded there within and configured to emit spectrally controllable radiation; and (c) a back portion configured to reflect the radiation emitted by the spectrum conversion layer to the cultivated crops. The back portion has a central area being adjacent to the optically transparent middle body portion configured for reflecting radiation propagating within the optically transparent middle body portion and a peripheral area configured for reflecting radiation emerged from the optically transparent middle body portion via the side surface.
