Impembelelo ye-thermal kwi-LED ihambelana ngokungafaniyo nombane ohamba phambili, i-VF. Xa izinga lokushisa linyuka, i-voltage yangaphambili iyancipha, inyusa ukuhamba kwangoku kwii-LEDs. Kwaye ukuhamba ngokugqithisileyo kwangoku kunokuchaphazela kakubi ukusebenza kwe-fixture.

Enye impembelelo eshushu ye-LED binning yimpembelelo kwi-flux ekhanyayo ye-LED. Ukukhanya okukhanyayo kwe-LED kuchaphazeleka bubushushu be-LED. Njengoko iqondo lokushisa linyuka, i-flux ekhanyayo iyancipha. Kwaye ke, ichaphazela ngokuthe ngqo ukukhanya kokukhanya.

Ukongeza, ulawulo lwe-thermal lunokuchaphazela ubomi bubonke be-LED. Njengoko ubushushu be-LED bukhula, izinga lokuwohloka kwe-LED nalo liyenyuka. Ikhokelela kubomi obufutshane. Ulawulo olufanelekileyo lwe-thermal lunokunceda ukunciphisa le mpembelelo. 

Imiba eqhelekileyo okanye imingeni nge-LED Binning

Ngelixa i-LED idibanisa, unokujongana nemiba eqhelekileyo, ebandakanya:

• Ukwahluka koMbala: Kwinkqubo yokubopha i-LED, ukuhlelwa kunye nokuhlelwa kwee-LED kuyenziwa, kugcina uphawu lwemibala kuyo yonke imigqomo rhoqo. Ukanti, ezinye ii-LED zinokuba notshintsho oluncinci kumbala. Zinokuchaphazela ukubonakala kwenkqubo yokukhanyisa.

• Ukuhla kweLumen: I-LED binning ikwahlela ii-LED ngokuguquguquka kwazo okukhanyayo kunye nokukhanya. Nangona kunjalo, ekuhambeni kwexesha, ukukhanya kwe-LED kunokuncipha, okubizwa ngokuba kukuhla kwe-lumen. Oku kunokubangela ukukhanya okungalinganiyo kwaye kuchaphazele ukusebenza kwenkqubo.

• Ukubhinca okungalunganga: Ukuba ii-LED azihlelwanga ngokuchanekileyo okanye zibekwe ngokwamaqela ngexesha lenkqubo yokubhina. Ingakhokelela ekungahambelaniyo ekusebenzeni kunye nombala. Oku kunokubangela imiba ngenkqubo yokukhanyisa.

• Iindleko: Binning LEDs inokuba yinkqubo ebiza kakhulu. Ifuna izixhobo ezikhethekileyo kunye nabasebenzi abanezakhono. Ngoko ke, oku kunokuchaphazela ixabiso elipheleleyo lenkqubo yokukhanyisa.

UVavanya njani iBinned LED?

Ukuvavanya i-LED ebotshiweyo, kufuneka ulandele la manyathelo:

Inyathelo 1: Qhagamshela i-LED kuMthombo waMandla: Qhoboshela i-LED ye-positive lead kwi-terminal evumayo yomthombo wamandla. Emva koko uchukumisa iintlawulo ezingalunganga kwi-terminal engalunganga. Kwaye ke jonga ukuba i-LED iyakhanya okanye ayikhanyisi. 

Inyathelo lesi-2: Ukulinganisa iVoltage kunye neyangoku: Sebenzisa i-multimeter ukulinganisa i-voltage kwi-LED kunye nokuhamba kwangoku kuyo.

Inyathelo 3:Bala ixabiso leSixhasi: Sebenzisa umthetho we-Ohm ukubala ixabiso le-resistor. Ifomula ithi R = (Vsource – Vf) / Ukuba

Inyathelo lesi-4: Thelekisa ufundo kunye neNgcaciso: Jonga i-database ye-LED ukuze ubone ukuba yintoni i-voltage elindelekileyo kunye neyangoku kufuneka ibe yiloo LED edibeneyo. Thelekisa ufundo olusuka kwi-multimeter kunye neenkcukacha.

Inyathelo lesi-5: Qwalasela iPhumo lokuKhanya: Ukuba i-voltage kunye nokufundwa kwangoku kuhambelana neenkcukacha, jonga ukuphuma kokukhanya kwe-LED. Ukuba ayisiyiyo njengoko kulindelekile, kunokubakho ingxaki nge-LED.

Inyathelo lesi-6: Phinda uVavanyo ngeMithombo yaMandla eyahlukeneyo: Phinda uvavanyo ngemithombo eyahlukeneyo yamandla ukuqinisekisa ukuba imisebenzi ye-LED ngokuchanekileyo.

Phawula: Ii-LED ezidibeneyo zihlelwe ngokusekelwe kumbane wazo wangaphambili kunye nokhoyo. Kubalulekile ukuvavanya la maxabiso ukuqinisekisa ukuba i-LED isebenza ngokuchanekileyo.

Iingcebiso zokuLungisa iNkqubo yakho yokuBinning ye-LED

• Cacisa ngokucacileyo iiparamitha ze-binning ze-LED ozifunayo: Chonga iiparamitha onqwenela ukuzisebenzisa xa ubhina. Okufana nobushushu bombala, ukuguquguquka okukhanyayo, kunye nombane ohamba phambili. Oku kuya kuqinisekisa ukuba zonke ii-LED zivavanywa ngokweenqobo zokugweba ezifanayo.

• Sebenzisa indlela yovavanyo engaguqukiyo: Sebenzisa iindlela zovavanyo ezingaguqukiyo kuyo yonke inkqubo yokubhina. Oku kunokubandakanya ukusebenzisa izixhobo ezifanayo kunye nobuchule bokulinganisa, kwakhona, iimeko zokuvavanya kwi-LED nganye.

• Sebenzisa isoftware yokufaka i-automated binning: Isoftware yokufaka i-automated inokwenza lula inkqubo yokubopha. Kwakhona, kunokunciphisa amathuba okuba neempazamo zabantu. Ezi nkqubo zinokuhlenga ngokuzenzekelayo ii-LEDs zibe yimigqomo eyahlukeneyo.

• Gcina iirekhodi ezineenkcukacha: Ukugcina iirekhodi ezineenkcukacha kunokunceda ukulungisa nayiphi na imiba enokuthi ivele. Ngokunjalo nakwixesha elizayo. Oku kunokubandakanya ulwazi malunga nezixhobo zovavanyo ezisetyenzisiweyo. Kwakhona, i parameters binning kunye neziphumo zovavanyo ngalunye.
