    摘要： 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.

    摘要： A diffractive optical element and a method to produce same is disclosed. The optical element comprises a base and at least first and second phase zones wherein the first phase zone comprises a first multiplicity of steps and the second phase zone comprises a second multiplicity of steps and wherein the first multiplicity and the second multiplicity of steps are different. The method to produce the diffractive optical element of the present invention includes the step of defining a collection of masks for creating stepped phase zones wherein at least one of the collection of masks partially masks out at least one phase zone such that the at least one phase zone will be partially etched.

    摘要： There is disclosed a diffractive optical element and a method to produce same wherein the element comprises a base and at least one phase zone comprising an arbitrary multiplicity M of steps of generally identical step height, wherein M is not a power of 2. The method includes the steps of defining a basic depth unit equivalent to a zone height divided by M, defining a depth sequence of N depths wherein N is the smallest integer greater than log.sub.2 M such that each of the M steps can be produced by at least one linear combination of the N depths, defining N masks herein each mask enables the optical element to be processed to one of the N depths and wherein for each mask, the steps to be processed are those which have the one of the N depths in its linear combination and serially utilizing each of the N masks for processing of the optical element.
