Izinto ezi-5 zokujonga xa uthelekisa uyilo lokukhanyisa kwizibane ze-LED ezikhulayo

Xa uthelekisa uyilo lokukhanyisa olwahlukileyo, qiniseka ukuba uthelekisa iiapile kunye neeapile. Oku kuthetha ukuba uthathela ingqalelo izinto ezi-3:

1. Qinisekisa ukuthembeka kwamabango entsebenzo eyenziwa ngabavelisi.
2. Qinisekisa ukuba isoftware yokubala ye-DIALux isetyenziselwa uyilo lokukhanyisa. Le software yokubala inikezelwa yinkampani ezimeleyo kwaye isetyenziswa ngokuqhelekileyo kwimarike yokulima.
3. Khangela ukuba zeziphi iiparameters ezisetyenzisiweyo kuyilo ngalunye lokukhanyisa. Kulula ukudibanisa iiparamitha zegalelo kwaye unike imbonakalo yenqanaba lokukhanya elilungileyo kunye nokufana ngaphakathi koyilo lokukhanyisa. Zeziphi ke iiparameters ezibalulekileyo?

Ezona parameters zibalulekileyo ekufuneka zijongwe zezi:

• Ngaba imveliso efanelekileyo ichaziwe?Jonga ukuba eyona mveliso oyikhethileyo yeprojekthi yakho isetyenzisiwe kuyilo lokukhanyisa, kunye nemveliso yokukhanya echanekileyo (PPF nge µmol/s) kunye nesspectrum (blue/red/white/red red/…).
• Ngaba amaxabiso akho oyilo asetyenzisiweyo,njengomgangatho wokukhanya ophakathi kwisityalo sakho (PPFD nge µmol/m²/s) kunye nokufana kokukhanya ngokubanzi?
• Ziziphi iisetingi eziqhelekileyo?Ubude bokukhula kokukhanya kunye nesityalo (ubude obukhululekile), imiba yokubonakalisa, kunye nobukhulu kunye nokuma kwendawo esetyenziswayo kubalo olufanayo zonke zinempembelelo kumgangatho wokukhanya ophakathi kunye nokufana ngokubanzi okuphunyeziweyo.

Iparameter yokuqala yokujonga kubude obukhululekileyo obuchaza umgama phakathi kwemodyuli ye-LED kunye nentloko yesityalo. Ubude obukhululekile bunokuba nefuthe elibi kwixabiso elilinganayo. Kwizityalo ze-tomato ezinocingo oluphezulu olunobude obulinganiselweyo obuyi-1.50 ukuya kwi-2.50 m, umzekelo, kunokuba ngumngeni ukufezekisa ixabiso elihle lokufana. Ukusebenzisa umphakamo othembisayo okhululekileyo okanye ukubala ukufana kumgangatho ngokungathi akukho sityalo, kuya kuba nefuthe elincomekayo kwixabiso lokufana lilonke.

Umphakamo okhululekileyo ubalwa ngokulinganisa umgama phakathi komphezulu wesityalo wokugqibela kunye nokuphakama kokukhanya kwe-LED.

Enye iparameter ebalulekileyo ukujonga, zizinto ezibonisayo ezisetyenziswe kwisicwangciso sokukhanyisa. I-reflection factor ibonisa ubuninzi bokukhanya okubonakaliswa ngeendonga kunye nezinye izinto kwisithuba. Isoftware yokubala ye-DIALux iqale yenzelwe iindawo zangaphakathi ezinje ngee-ofisi, apho uya kufumana imbonakalo eludongeni, isilingi kunye nemigangatho enefuthe lokukhanya kwidesika yakho. Ukunqanda ukuba nethemba kakhulu malunga nesiphumo, amaxabiso okubonakalisa kwi-DIALux abekwe kwi-0% yoyilo lokukhanyisa izibane, kuba iglasi ekwindlu eluhlaza ayibonakalisi ukukhanya okuvela kwizibane ezikhulayo.

Into elandelayo ekufuneka ijongwe ngumphezulu wokubala oye wachazwa. Ubungakanani bendawo yokubala kunye nendawo yezibane zokukhula phakathi kwaloo ndawo buya kuchaphazela ngokunzulu umlinganiselo wesixa seefotoni ezisebenzayo ezifikelela kumphezulu wesityalo (ixabiso lePPFD ngeµmol/m2/s). Xa uthelekisa iziphumo zoyilo lokukhanyisa ezivela kubavelisi abohlukeneyo, qinisekisa ukuba umphezulu wokubala ubonisa inani elilinganayo lobukhulu (iincopho) kunye nobuncinci (iidiphu) zamaxabiso okukhanya kokukhanya. Le kuphela kwendlela yokubala i-avareji eyinyani yexabiso lePPFD kuyilo lokukhanyisa.

Kulo mzekelo ungezantsi, ubona iindawo ezimbini zendawo yokubala ngaphakathi kwesicwangciso sokukhanya esifanayo. Masicinge ukuba iincochoyi zokukhanya zibekwe ngokuthe ngqo ekukhuleni kokukhanya kunye nokukhanya kokukhanya phakathi kwezibane ezikhulayo ezimbini. Amaxabiso kwimiba ye-B azakuvelisa amaxabiso angcono omndilili wokukhanya, kuba ubunzulu bokukhanya bubalwa kwindawo ebonisa iincopho ezi-4 kunye no-1 dip. Imeko engu-A ibonisa iincopho ezi-4 kunye neediphu ezi-4, kwaye ngenxa yoko imele inyani yokwenyani emva kofakelo.

Enye into ebalulekileyo bubukhulu bomphezulu wokubala obuya kuba nefuthe kwixabiso elilinganayo. Xa uthelekisa iziphumo zoyilo lokukhanyisa ezivela kubavelisi abahlukeneyo, qiniseka ukuba indawo yokubala efanayo isetyenzisiwe.

Ukumela imeko yobomi bokwenene, ukubalwa kwendawo yecandelo elipheleleyo kufuneka lenziwe elibandakanya imida ye-greenhouse. Ubalo lwendawo encinci esembindini, emele indawo yemveliso eqhelekileyo nayo kufuneka yenziwe. Ubalo lwekhompatimenti epheleleyo luya kuvelisa amanqanaba asezantsi afanayo okukhanya, ngenxa yokukhanya okuphantsi kokukhanya emiphethweni. Ke, qiniseka ukuba uhlala uthelekisa nokubalwa kwamacandelo apheleleyo okanye iindawo ezincinci ngaphakathi kwecompartment.ple engezantsi, ubona iindawo ezimbini zendawo yokubala ngaphakathi kwesicwangciso sokukhanya esifanayo. Masicinge ukuba iincochoyi zokukhanya zibekwe ngokuthe ngqo ekukhuleni kokukhanya kunye nokukhanya kokukhanya phakathi kwezibane ezikhulayo ezimbini. Amaxabiso kwimiba ye-B azakuvelisa amaxabiso angcono omndilili wokukhanya, kuba ubunzulu bokukhanya bubalwa kwindawo ebonisa iincopho ezi-4 kunye no-1 dip. Imeko engu-A ibonisa iincopho ezi-4 kunye neediphu ezi-4, kwaye ngenxa yoko imele inyani yokwenyani emva kofakelo.

Iparameter yokugqibela yokukhangela luhlobo lokufana olusetyenziswayo. Ukufana kunokubonakaliswa ngeendlela ezahlukeneyo. Xa uqhuba isoftware yoyilo lokukhanyisa iDIALux, ikubonelela ngeentlobo ezahlukeneyo zokufana. Xa uthelekisa iziphumo zoyilo lokukhanyisa ezivela kubavelisi abahlukeneyo, qiniseka ukuba uhlobo olufanayo lokubala lusetyenziswa. Kwisicelo se-horticulture sikhetha ukuvakalisa ukufana njengokukhanya okuphakathi kokukhanya okwahlulwe ngokukhanya okukhulu kokukhanya, okuyiyona nto imele imeko yokwenyani.

Xa uthelekisa uyilo lokukhanyisa kukho izinto ezininzi zokulungisa ababoneleli abanokuthi bazenze kwisicwangciso sabo. Ukuba ufuna ukwenza uthelekiso olufanelekileyo, kufuneka uthathele ingqalelo iiparamitha ezimbalwa.

• Ngaba imveliso echanekileyo, ene-spectrum efanelekileyo kunye nemveliso yokukhanya, isetyenziswe kwizibalo?
• Ingaba inqanaba lokukhanya elichanekileyo kwisityalo sakho kunye nokulingana kokukhanya okufanelekileyo kusetyenzisiwe?
• Ngaba iisetingi ziyathelekiseka:
  - Ingaba umphakamo okhululekileyo uchazwe ngokuchanekileyo?
  - Ingaba imiba yokubonisa imiselwe ku-0%?
  - Ngaba igridi yokulinganisa inenani elilinganayo lokukhanya kunye namabala amnyama kuyo?
  - Ngaba uthelekisa indawo egcweleyo okanye amanani amancinci aphakathi
  - Kwaye ngaba ukufana kuchazwa ngokufanayo kwiiyilo zokukhanyisa?
