Izinto ezi-5 okufanele uzihlole lapho uqhathanisa imiklamo yokukhanyisa izibani ezikhulayo ze-LED

Uma uqhathanisa imiklamo ehlukene yokukhanyisa, qiniseka ukuthi uqhathanisa ama-apula nama-apula. Lokhu kusho ukunaka izinto ezi-3:

1. Qinisekisa ukwethembeka kwezimangalo zokusebenza ezenziwa abakhiqizi.
2. Qinisekisa ukuthi isofthiwe yokubala ye-DIALux isetshenziselwa umklamo wokukhanyisa. Le software yokubala ihlinzekwa yinkampani ezimele futhi ivame ukusetshenziswa emakethe ye-horticulture.
3. Hlola ukuthi imaphi amapharamitha okokufaka asetshenziselwe umklamo ngamunye wokukhanyisa. Kulula ukulungisa amapharamitha okokufaka futhi unikeze umbono wezinga lokukhanya elihle kakhulu kanye nokufana ngaphakathi komklamo wokukhanyisa. Ngakho yimaphi amapharamitha abalulekile?

Izinhlaka zokufaka ezibaluleke kakhulu okufanele zihlolwe yilezi:

• Ingabe umkhiqizo olungile ucacisiwe?Hlola ukuthi umkhiqizo oqondile owukhethile wephrojekthi yakho usetshenzisiwe yini ekwakhiweni kokukhanyisa, ngokuphuma kokukhanya okulungile (i-PPF ngo-µmol/s) kanye ne-spectrum (okuluhlaza okwesibhakabhaka/obomvu/okumhlophe/okubomvu kakhulu/…).
• Ngabe kusetshenziswe amanani edizayini yakho ethile,njengesilinganiso sezinga lokukhanya kusinqamuleli sakho (i-PPFD ku-µmol/m²/s) kanye nokufana kokukhanya sekukonke?
• Yiziphi izilungiselelo ezijwayelekile?Ubude bokukhanya nokunqampuna (ubude obukhululekile), izici zokubonisa, kanye nosayizi nendawo yendawo esetshenziswa esibalweni sokufana konke kunomthelela ezingeni lokukhanya elimaphakathi kanye nokufana kukonke okufinyelelwe.

Ipharamitha yokufaka yokuqala okufanele ihlolwe ubude bamahhala obucacisa ibanga phakathi kwemojula ye-LED nenhloko yesitshalo. Ubude obukhululekile bungaba nomthelela omkhulu kunani eliphelele lokufana. Ezitshalweni zikatamatisi ezinocingo oluphezulu ezinobude obulinganiselwe bamahhala obungu-1.50 kuya ku-2.50 m, isibonelo, kungaba inselele ukuzuza inani elihle lokufana okupheleleyo. Ukusebenzisa ukuphakama kwamahhala okunethemba noma ukubala ukufana ezingeni laphansi njengokungathi asikho isilimo, kuzoba nomthelela omuhle enanini lokufana lilonke.

Ubude bamahhala bubalwa ngokulinganisa ibanga phakathi kwendawo engaphezulu yesitshalo kanye nobude obukhwezayo be-LED grow light.

Enye ipharamitha ebalulekile okufanele uyihlole, yizici zokubonisa ezisetshenziswa ohlelweni lokukhanyisa. I-reflection factor ibonisa inani lokukhanya eliboniswa izindonga nezinye izinto ezisesikhaleni. Isofthiwe yokubala ye-DIALux ekuqaleni yakhelwe izindawo zasendlini njengamahhovisi, lapho uzothola khona ukukhanya odongeni, ophahleni naphansi okuthinta izinga lokukhanya edeskini lakho. Ukuze ugweme ukuba nethemba elikhulu ngomphumela, amanani wokuboniswa ku-DIALux asethwe ku-0% edizayini yokukhanyisa okubamba ukushisa, ngoba ingilazi esendlini ebamba ukushisa ayikubonisi ukukhanya okuvela ezibanini ezikhulayo.

Okulandelayo okufanele kuhlolwe indawo yokubala echaziwe. Usayizi wendawo yokubala kanye nokuma kwezibani ezikhulayo kuleyo ndawo kuzothinta kabi inani elimaphakathi lama-photon asebenzayo afinyelela phezulu kwesitshalo (ivelu ye-PPFD ku-µmol/m2/s). Uma uqhathanisa imiphumela yedizayini yokukhanyisa evela kubakhiqizi abahlukene, qiniseka ukuthi indawo yokubala ikhombisa inani elilinganayo lamanani aphezulu (ama-peaks) kanye nobuncane (ama-dips) amanani wokukhanya. Lena ukuphela kwendlela yokubala inani langempela le-PPFD eliyisilinganiso edizayini yokukhanyisa.

Esibonelweni esingezansi, ubona izindawo ezimbili zendawo yokubala ngaphakathi kohlelo lokukhanya olufanayo. Ake sicabange ukuthi iziqongo zamandla okukhanya zitholakala eduze kokukhanya okukhulayo futhi amandla okukhanya angena phakathi kwezibani ezimbili ezikhulayo. Amanani esigcawini sika-B azokhiqiza amanani angcono kakhulu esilinganiso sokukhanya, ngoba amandla okukhanya abalwa endaweni ebonisa ukuphakama okungu-4 kanye nediphu engu-1. Isimo sika-A sibonisa iziqongo ezi-4 namadiphu angu-4, futhi ngenxa yalokho simelela kangcono iqiniso ngemva kokufakwa.

Esinye isici esibalulekile ubungako bendawo yokubala obuzoba nomthelela enani eliphelele lokufana. Uma uqhathanisa imiphumela yedizayini yokukhanyisa evela kubakhiqizi abahlukene, qiniseka ukuthi indawo yokubala efanayo isetshenzisiwe.

Ukumela isimo sangempela sokuphila, ukubalwa kwendawo egcwele yegumbi kufanele kwenziwe okuhlanganisa imiphetho ye-greenhouse. Isibalo sendawo encane emaphakathi, emele indawo ejwayelekile yokukhiqiza kufanele futhi yenziwe. Isibalo sekhompathimenti egcwele sizokhiqiza amazinga aphansi afanayo wokukhanya, ngenxa yokuqina kokukhanya okuphansi emaphethelweni. Ngakho-ke, qiniseka ukuthi uhlale uqhathanisa izibalo zekhompathimenti egcwele noma izindawo ezincane ngaphakathi kwekhompathimenti egcwele.ple ngezansi, ubona izindawo ezimbili zendawo yokubala ngaphakathi kohlelo lokukhanya olufanayo. Ake sicabange ukuthi iziqongo zamandla okukhanya zitholakala eduze kokukhanya okukhulayo futhi amandla okukhanya angena phakathi kwezibani ezimbili ezikhulayo. Amanani esigcawini sika-B azokhiqiza amanani angcono kakhulu esilinganiso sokukhanya, ngoba amandla okukhanya abalwa endaweni ebonisa ukuphakama okungu-4 kanye nediphu engu-1. Isimo sika-A sibonisa iziqongo ezi-4 namadiphu angu-4, futhi ngenxa yalokho simelela kangcono iqiniso ngemva kokufakwa.

Ipharamitha yokugcina okufanele ihlolwe wuhlobo lokufana olusetshenziswayo. Ukufana kungavezwa ngezindlela ezahlukene. Uma usebenzisa isoftware ye-DIALux yokuklama izibani, ikunikeza izinhlobo ezahlukene zokufana. Uma uqhathanisa imiphumela yomklamo wokukhanyisa evela kubakhiqizi abahlukene, qiniseka ukuthi uhlobo olufanayo lokubala lokufana luyasetshenziswa. Ngohlelo lokusebenza lwe-horticulture sikhetha ukuveza ukufana njengokuqina kokukhanya okumaphakathi okuhlukaniswe ubukhulu obukhulu bokukhanya, obumelela kangcono isimo sempilo yangempela.

Uma uqhathanisa imiklamo yokukhanyisa kunenqwaba yama-tweaks abahlinzeki abangahle bayenze ohlelweni lwabo. Uma ufuna ukwenza isiqhathaniso esifanele, kufanele ucabangele amapharamitha ambalwa.

• Ingabe umkhiqizo olungile, one-spectrum efanele kanye nokuphuma kokukhanya, usetshenzisiwe ekubalweni?
• Ingabe izinga lokukhanya elilungile lesitshalo sakho kanye nokufana kokukhanya okuphelele kusetshenzisiwe?
• Ingabe izilungiselelo ziyaqhathaniswa:
  - Ingabe ubude bamahhala buchazwe kahle?
  - Ingabe izici zokubonisa zisethwe ku-0%?
  - Ingabe igridi yokulinganisa inenani elilinganayo lamachashaza akhanyayo namnyama kuyo?
  - Ingabe uqhathanisa indawo egcwele noma izinombolo zendawo emaphakathi
  - Futhi ingabe ukufana kuchazwa okufanayo emiklamo yokukhanyisa?
