3 Amathrendi amaningi okwenza izixazululo ze-LED zibe yizinga le-horticulture

Ukungena kwe-LED ebonakalayo
Kungani ukushintsha kwe-paradigm? Ngesizathu esilula ukuthi ukukhanya kwe-LED kunomthelela ozwakalayo kumathrendi amathathu abalulekile emhlabeni jikelele.

Inani labantu emhlabeni elikhulayo
Inani labantu emhlabeni likhula ngokushesha. Izazi zabantu babona kusengaphambili iplanethi okuyothi ngonyaka ka-2050 ibe nabantu abayizigidi eziyizinkulungwane ezingu-10, abaningi ngokwengeziwe abahlala emadolobheni. Njengoba lokho kuthambekela kwezibalo zabantu kuqhubeka, ukutholakala kokudla kuzoba inselele ebaluleke kakhulu kohulumeni bamazwe. Yilokho ikakhulukazi uma kubhekwa ukuba sengozini kwe-supply chain okuvezwe ubhubhane lwe-COVID-19.

Enye indlela yokuthi abaholi bavikele imithombo yabo yokudla iwukuthuthukisa ezolimo zasekhaya. I-Russia, i-US, i-China, i-Singapore, ne-Turkey zonke seziqalile ukutshala izimali ezisekelweni zokukhiqiza ukudla zonyaka wonke. Izindlu zokugcina izithombo zobuchwepheshe obuphezulu—ngokungenakugwenywa zifakwe ubuchwepheshe besimanje, kuhlanganise ne-LED—ziyimfuneko yokufeza ukutholakala kokudla unyaka wonke.

Futhi kanjalo namapulazi aqondile anikwe amandla e-LED aphezulu. Bazokwenza kanjalo ikakhulukazi emadolobheni omhlaba ahlala eminyene kakhulu futhi elokhu elambile, esiza ekunciphiseni inani lamakhilomitha ukudla nezimbali eziwahambayo ukusuka kwelinye iphuzu kuye kwelinye. Futhi zizovela ezindaweni lapho ukukhiqizwa kokudla noma i-floriculture ezindaweni zokugcina izithombo kungeyona inketho ngenxa yezizathu zezulu.

Ukuguquka kwesimo sezulu kanye nokusimama
Bese kuba ne-geopolitics kanye nesidingo sokuhamba sibe luhlaza futhi siqhubekele phambili. Isivumelwano saseParis sibophezela amazwe ukuthi anciphise ukukhishwa kwekhabhoni. Lowo msebenzi uba lula uma sebemukele ubuchwepheshe be-LED obuzinzile. Uxhaso lwe-LED lukahulumeni luzophoqa abalimi ukuthi benze i-LED ibe yizinga elisha lemboni yezolimo, kanye nokusebenza kahle kwangaphakathi kwe-LED nezinye izinzuzo ngaphezu kwe-high-pressure sodium (HPS) kuzosiza ukufeza lowo mgomo.
Ngaphandle kwalokho, izinqubo ezisimeme ziya ngokuya ziba yimfuneko emnothweni wethu—futhi lokho akubangelwa nje kuphela ukuthi zenza kube nombono omuhle nokuziphatha okuhle. Yingoba zilungele ibhizinisi. Abalimi abafuna ukuba luhlaza bathola ukuthi ukusebenzisa ubuchwepheshe be-LED kuzothuthukisa amazinga abo okukhiqiza noma ikhwalithi yomkhiqizo njengoba kunciphisa ukusetshenziswa kwabo kwamandla kanye nokukhishwa kwe-CO2.

Njengoba izibani ezifiphalayo nezishintshashintshayo zikhula kanye nolwazi mayelana nendlela yokuthuthukisa ukukhiqizwa kuthuthuka, indawo ye-LED ye-ecological footprint izokwehla nakakhulu. Imishini enjalo izovumela umlimi ukuthi alungise amanani okukhanyisa kanye ne-spectra ngokuhambisana nezidingo zezitshalo ezithile kanye nomzuzwana nomzuzwana, ecabangela isimo sokukhula kwesitshalo, inani lokukhanya kwemvelo elingena endaweni, njalonjalo.

Indlela eqhubekayo esimeme kakhudlwana yezindlu ezibamba ukushisa izonikwa amandla nayo izokwenza i-LED ibaluleke nakakhulu. Imithombo yamandla evuselelekayo, njengomoya nelanga, ezothatha ingxenye enkulu yengxube yamandla ikhiqiza amandla aqondile. Lokho kuwukulingana okungcono kakhulu kwe-LED kunokukhanya kwe-HPS okusabusa kwezolimo.

Isidingo sabathengi/izitolo
Nakuba izinqubo ezisimeme zibaluleke kakhulu kunangaphambili, ukusetshenziswa kokudla emhlabeni wonke ngeke kwehle, kodwa isidingo semikhiqizo enempilo esezingeni eliphezulu sizokhula. Futhi uma sifuna ukuvumelanisa izidingo zabathengi nomgomo wethu wokuvikela imvelo, kufanele sihlakaniphe. Enye indlela yokufeza lokhu ukwenza i-LED ibe yizinga.
Ukuqinisekisa ikhwalithi yomkhiqizo, izimbali nezitshalo unyaka wonke, phela, kudinga ukukhanya okuzinzile, okungeyona into ehlinzekwa yimvelo. Abalimi bazame ngempumelelo ukukhanya kwe-HPS okungeziwe—kodwa i-LED esebenza kahle, evumelana nezimo kakhudlwana ingenza izinqubo zabo zibikezeleke kakhulu futhi zingasebenzisi kakhulu izinsiza.

Ingenza futhi umkhiqizo, izimbali nezitshalo zibe nempilo kubathengi. Amanani alungile okukhanya, esibukweni esifanele, alethwa kusetshenziswa izindlela zokupheka zokukhanya okuguquguqukayo, angakhuphula ukuqina kwesitshalo, anciphise noma aqede isidingo samakhemikhali. Ukukhanya okulungile kungaqinisekisa nokuthi izitshalo ziqukethe imisoco efunwa abathengisi abathile noma izisekelo zamakhasimende.

Ibheke kwikusasa le-LED
I-LED ikhuphukela phezulu njengesixazululo sokukhanyisa kwezolimo emandleni ezitayela eziningi ezinkulu: ukwanda kwesibalo sabantu emhlabeni wonke, ukusimama, kanye nesidingo esikhulayo esivela kubathengi abanokuqonda okwengeziwe. Njengoba iqhubeka iba yizinga lomhlaba wonke, i-LED izovumela ukuqanjwa okudingeka kakhulu endleleni esikhulisa ngayo izinto-futhi i-Sigify, ne-suite yayo eguqukayo yezixazululo zokukhanyisa, izohlala ingumholi kulo mkhakha.
