Kwiminyaka yakutshanje, ukusetyenziswa kwezibane ezikhulayo ze-LED kuye kwanda kakhulu. Ecaleni koku, inani lababoneleli abatsha abaneemveliso ezingangqinwanga linyukile nalo. Abanye benza amabango athandabuzekayo malunga nokusebenza kwemveliso yabo, nto leyo idala ukubhideka malunga nokuba zeziphi izibane ezikhulayo ze-LED ezinokukhetha kunye nendlela yokuthelekisa ii-apile neeapile. Sebenzisa ezi ngcebiso zintathu zilandelayo ukugweba ukusebenza kunye namabango obomi enziwe ngababoneleli bokukhanya be-LED, ngokusekwe kwezona mpawu zibalulekileyo zichaza ukusebenza.

#1 Jonga ukusebenza kokuqala kunye nokusebenza ngexesha elibangwayo

Ukusebenza kokuqala kunye nokusebenza ngokuhamba kwexesha zombini zichaza ubude bokukhanya kokukhula. Kodwa nganye ilinganiswa njani kwaye ababoneleli bawasebenzisa njani la manani? Njengomlimi, ufuna ukwazi kwangaphambili ukuba izibane zakho ziya kuhlala ixesha elingakanani. Ke ayisiyiyo kuphela isixa sephoton flux kwasekuqaleni ebalulekileyo, kodwa nokuba iya kuyigcina njani le mveliso kwiminyaka oyisebenzisayo. Ukudala ukukhanya okupheleleyo ekusebenzeni kwezibane ze-LED ezikhulayo, kubalulekile ukuzisebenzisaimigangatho yamazwe ngamazweukuvelisa idatha yemveliso efanayo. Le migangatho ichaza indlela yokulinganisa ukusebenza kokuqala kunye nokubonelela nge-metric yobomi okanye ifomula yokubala ukusebenza ngexesha.

Jonga zombini intsebenzo yokuqala kunye nokusebenza ngexesha elibangwayo.

Ilinganiswa njani intsebenzo yokuqala?

Amaxabiso okuqala okusebenza ayasebenza kwisibane esitsha sokukhulisa i-LED. Iimfuno eziqhelekileyo ezinokusetyenziswa njengegalelo kuyilo lokukhanyisa zezi:

1. Ifoton flux [PFD okanye PPFD in µmol/s] – isixa seefotoni ezisebenzayo ezifikelela kumphezulu wesityalo ekuhambeni kwexesha.
2. Unikezelo lwamandla eSpectral [nm] – yeyiphi imibala esetyenziswayo ekulawuleni ukukhula kwesityalo.
3. Amandla asetyenzisiweyo [W] – ungakanani umbane osetyenziswa sisibane sokukhulisa.
4. Ukusebenza kakuhle kwenkqubo [µmol/J] – ukukhanya okukhulayo kusebenzisa ngokufanelekileyo kangakanani amandla ako ukukhanyisa isityalo.
5. Ukuhanjiswa kokukhanya - yeyiphi iphethini esetyenzisiweyo kunye nendlela ngokufana ngayo ukukhanya kusasazwa.

I-photon flux kunye namandla asetyenzisiweyo alinganiswa ngokuqhelekileyo kwinto ebizwa ngokuba yi-sphere yokudibanisa. Ukusasazwa kwamandla okukhanya kunye nokuhanjiswa kokukhanya, i-gonio spectrometer iyafuneka. Ayingabo bonke abavelisi bokukhanya be-LED abanelabhoratri yokulinganisa okanye ukukwazi ukulinganisa ngokwemigangatho. Abo bahloniphekileyo baya kusebenzisa iinkonzo zebhubhoratri eqinisekisiweyo ezimeleyo.

I-signify isebenzisa ilabhoratri yayo yokulinganisa evunyiweyo ukulinganisa ukusebenza kokuqala kwezibane zethu ze-LED ezikhula ngokwemigangatho yokusebenza kwe-IEC. Ilabhoratri yethu ihlolwe kwaye iqinisekiswe ngumzimba ogunyazisiweyo, i-DEKRA, ngoko siyazi ngokuqinisekileyo ukuba izixhobo zisebenza ngokwemigangatho yamazwe ngamazwe kwaye zilinganiswe ngamaxesha.

Uqikelelwa njani umsebenzi ekuhambeni kwexesha?

Ukusebenza ngexesha elide akunakulinganiswa ngexesha lokuziswa kwemveliso. Akunakwenzeka ukwenza uvavanyo, umzekelo, kwiiyure ezingama-60,000 zokusebenza ukubanga ukusebenza okunjalo ekuhambeni kwexesha. Iimvavanyo eziqhelekileyo ziqhuba phakathi kwe-6,000 kunye ne-10,000 yeeyure.

Kukho amaxabiso amabini afanelekileyo okusebenza 'ngokuhamba kwexesha' ekufuneka aqwalaselwe anxulumene nokuthotywa kokukhanya kwe-LED:

• Ukuthotywa kwemveliso ngokuthe ngcembe kuhambelana nokuhla kwe-photon flux ye-LED ikhula ukukhanya ngokuhamba kwexesha. Ikuxelela ukuba ingakanani imveliso yokuqala ye-photon flux egcinwe emva kwexesha elithile. I-photon flux depreciation ingaba yindibaniselwano yokuthotywa kwezinto ezibonakalayo ezisetyenzisiweyo, ii-LED zomntu ngamnye zinika ukukhanya okuncinci kunye nee-LED ezizimeleyo zinika ukukhanya konke konke. Ukuthotywa kwemveliso kancinane kuchazwa yifoton flux depreciation [%].
• Ukuthotywa ngokukhawuleza kwemveliso yokukhanya ebonakaliswa ngamaqhezu eemveliso ezingaphumelelanga [%] ngexesha elithile.

Ubalo olusuka kwi-Signify lusekwe kwidatha yovavanyo lonyamezelo lokwenyani lweebhodi ze-LED esizisebenzisayo, uvavanyo olukhawulezileyo lwamacandelo abalulekileyo kunye nokuqonda okunzulu ukuba zeziphi iiparamitha zoyilo ezibaluleke kakhulu ekwandiseni ukukhanya kwe-LED kubomi bonke. I-signify iphuhlise isixhobo sokuqikelela ukuhla kwe-photon flux kunye neqhezu leemveliso ezingaphumeleliyo kwizibane zethu ze-LED.

#2 Jonga ngononophelo ixesha lobomi obangwa ngalo isibane sokukhulisa i-LED

Izibane ze-LED ziyindlela yokuvelisa umlimi, ngoko ke iingxoxo zobomi zigxile ikakhulu kukwehla kwexabiso lephoton. Kuba ixesha elilindelweyo lokuphila kwezibane ze-LED lihlala lide kakhulu, ezo zixa zeeyure ezibangwayo azinakulinganiswa phambi kokuba imveliso yaziswe emarikeni. Ke ngoko, abavelisi basebenzisa imilinganiselo emifutshane kwaye bakhuphe ezo zichaze iingqikelelo zabo ngokuhamba kwexesha. Oku kufuna ukuqonda okunzulu ukuba zeziphi iiparamitha zoyilo ezibalulekileyo ekwandiseni ukukhanya kwe-LED kubomi bonke, kunye nolwazi olwaneleyo lwamanani ukwenza izibalo ezichanekileyo. Ayingabo bonke ababoneleli abakwenzayo oku ngendlela efanayo, ke ngoko, ngendlela enokuthelekiseka. Ngenxa yoko, umgangatho woqikelelo lobomi uyahluka kakhulu.

Kukho imigangatho embalwa eyaziwayo kumazwe ngamazwe ethi Signify isebenzise xa iqikelela ubomi bemveliso. Nazi ezimbini zazo:

• I-IES LM-80 ichaza indlela yokulinganisa ukugcinwa kwe-photon flux ngexesha le-LED
• IES TM-21 ichaza indlela yokwenza uqikelelo lobomi obufanayo obusekwe kwiziphumo zovavanyo lwe-LM-80

Xa usebenzisa umgangatho we-LM-80, ubuncinane beeyure ze-6,000 zokuvavanya iphakheji ye-LED iyafuneka. Ewe kunjalo, izibane ezikhulayo ze-LED ziyakwazi ukuphila ubomi obungaphaya kweeyure ezingama-6,000. Kulapho kungena khona umgangatho we-TM-21. I-TM-21 ikuvumela ukuba wenze uqikelelo lobomi ngokuphinda-phinda ubude bobomi obuqokelelwe ngumgangatho we-LM-80 ukuya kuthi ga kumaxesha ama-6. Uvavanyo lomgangatho we-LM-80 ludla ngokuqhuba iiyure ezingama-6,000 ukuya kwezili-10,000, ngoko ke uqikelelo lobomi olusekwe kwi-TM-21 lukhokelela kuqikelelo oluya kutsho kwiiyure ezingama-36,000 ukuya kuma-60,000. Emva kweli xesha, akuthethi ukuba ukukhanya kwe-LED kuya kusilela, ngumda nje onokuthi ubangwe xa usebenzisa umgangatho wamazwe ngamazwe we-TM-21. Isizathu sokuba ungenakubanga ixesha elide usebenzisa lo mgangatho, kungokuba uqinisekisa ukuba uqikelelo alugqithi kumanqanaba okuzithemba kwamanani, nto leyo enokwenza ukuba bangathembeki. Oku kuthetha ukuba amabango angaphezulu kweeyure ezingama-60,000 akanakuqinisekiswa.

Ewe kunjalo, zikho ezinye izinto eziphembelela ixesha lokuphila le-LED likhula ukukhanya.Uyilongokwayo ibaluleke kakhulu, ngakumbi kuba yenzelwe ukulawula ubushushu obuveliswa zii-LEDs. I-optics, umqhubi kunye noyilo ziiparamitha ezichaza ukusebenza kwaye kufuneka ziqwalaselwe xa kuchazwa ixesha lokuphila. Njengomthengi, kufuneka uhlale ukhumbula ukuba ukusebenzisa ii-LED ezifanayo kwimveliso eyahlukileyo, akuthethi ukuba ukusebenza kwexesha kuya kufana.
