Samsung engineer will converse on specifying horticultural SSL

Because the second in a sequence of temporary HortiCann Gentle+Tech Convention highlights, we’re going to zoom in a bit of bit on the method of selecting LED-based solid-state lighting (SSL) merchandise for grower operation wants.

If you happen to’re specifying LED merchandise, in fact you first want to find out the necessities of the ability — supplemental greenhouse lighting could also be completely different from that utilized in a vertical farm or in managed atmosphere agriculture (CEA), because it’s additionally referred to as.

Past that, the cultivars concerned within the operation are equally vital. A tomato and a tulip can have very completely different must ship sturdy yields. A few of the variations can be within the depth or length of sunshine; the spectrum of sunshine that’s optimum for enhancing sure plant traits; how ultraviolet (UV) spectrum could also be utilized to enhance crop hardiness, plant vitamins, or resistance to pathogens; and so forth.

Photometric layouts generally is a useful a part of the method, as a few of our contributors from Independence LED described a few years again, however these initiatives will be complicated and there are numerous components to think about. Beginning with an in-depth understanding of the SSL merchandise and the inspiration of their improvement is essential. Samsung principal engineer Will Chung, whose upcoming speak is titled “What to consider when selecting LEDs for horticultural lighting,” will handle spectrum, lifetime, and efficacy from a product design viewpoint and can clarify how these engineering selections end in quite a lot of SSL merchandise that specifiers and installers can consider for his or her initiatives.

These are complicated subjects they usually definitely require multiple knowledgeable to interrupt them down into understandable chunks, so for those who had been considering this sounds a bit much like final week’s weblog on the effectivity presentation scheduled with Vic Zaderej, properly, I perceive. There may be a little bit of crossover, however let me deconstruct the variations: That presentation will actually concentrate on the metrics and methodology by which the effectivity of horticultural lights is established. We anticipate Chung will spend a lot of his presentation explaining some great benefits of merchandise designed with particular spectral energy distribution to attain the aforementioned horticultural operation goals. Efficacy will come into play because it is a crucial piece within the specifying and shopping for course of, however quite than summarize analysis that has resulted in commercializing more-efficient fixtures, Chung will tie collectively the product engineering and efficiency dialogue for instance the right way to consider and choose applicable LED luminaires.

Make your plans now to affix us at HortiCann on Oct. 31 in Denver, CO. For background on the parallel progress in funding and the creating marketplace for horticultural lighting and expertise, try Maury Wright’s function from our September 2019 concern.
