Popanga kuyatsa kwa LED, kuyika kwa LED ndikofunikira. Njirayi imatsimikizira ubwino ndi ntchito ya magetsi a LED. Koma kodi kuyika kwa LED ndi chiyani, ndipo kumakhudza bwanji nyali za LED zomwe mumagwiritsa ntchito tsiku ndi tsiku?

Kuyika kwa LED ndi njira yomwe imagwiritsidwa ntchito kuwonetsetsa kuti zinthu zowunikira za LED zikufanana komanso kugawira. Zimaphatikizanso kuyang'ana tchipisi tating'ono ta LED pakuwala kwawo, kutentha, ndi zina. Ndipo potero agawanitse m'magulu omwe ali ndi mawonekedwe ofanana.

M'nkhaniyi, ndifotokoza lingaliro la LED binning. Muphunziranso za mitundu yosiyanasiyana ya binning. Ndi momwe zimakhudzira magwiridwe antchito ndi mphamvu ya nyali za LED. Kotero, tiyeni tiyambe-

Kodi Binning ya LED ndi chiyani?

Kuyika kwa LED ndikusankha ndikuyika ma LED kutengera mawonekedwe awo, monga mtundu ndi kuwala. Kuphatikiza apo, izi zimatsimikizira kuti LED iliyonse mu batch ikukwaniritsa miyezo yeniyeni. Ndipo kotero inu mukhoza kugwiritsa ntchito makamaka ntchito. 

Izi zimathandiza opanga ndi makasitomala kuonetsetsa kuti ma LED omwe amalandira akukwaniritsa zomwe akufuna. Kuphatikiza apo, kuyika kwa LED kumawalola kuti apititse patsogolo kupanga kwawo komanso kuwongolera. 

Ubwino wa Binning ya LED

Kuyika kwa LED ndikofunikira kuti musunge mtundu wa kuyatsa kwa LED. Chifukwa chake zimabwera ndi zabwino zambiri, izi ndi izi- 

Kugwirizana Kwamtundu Wabwino

Kuyika kwa LED kumalola opanga kusanja ma LED ndi mtundu ndi kuwala. Izi zimatsimikizira kuti ma LED onse mu bin inayake ali ndi zinthu zofanana. Chifukwa chake, zimathandizira kukhazikika kwa chinthu chomaliza.

Kuchita Bwino 

Opanga amasankha ma LED kukhala nkhokwe kutengera momwe amagwirira ntchito. Mwachitsanzo, tchipisi zake zonse zimayesedwa kuti zikhale ndi mphamvu kapena kuwala kofanana popanga mizere ya LED. Ngati tchipisi onse siothandizanso, zotuluka sizingakhale zopindulitsa. Zosintha zonse zimayesedwa mu njira yolumikizira ya LED kuti ikhale yabwino. Ndipo izi zimawonjezera mphamvu yonse ya chinthu chomaliza.

Kuwongolera Kwabwino Kwambiri

Zosintha zonse zimayesedwa mu kuyika kwa LED, ndipo zida zosagwirizana zimachotsedwa. Zimathandizanso opanga kuzindikira ndi kuthana ndi mavuto ndi njira yawo yopangira. Chifukwa chake, kuyika kwa LED kumapangitsa kuti chinthu chomaliza chikhale bwino.

Mitundu ya Binning ya LED

Kusintha kwa ma LED kumapangidwa potengera malingaliro osiyanasiyana. Kutengera ndi izi, mutha kuphatikiza ma LED kukhala mitundu inayi yayikulu. Izi ndi izi- 

Mtundu Binning

Colour binning ndi njira yosanja ma LED potengera mtundu wawo. Izi zimatsimikizira kuti ma LED onse mu batch amakhala ndi mtundu wofanana komanso kulimba. Mutha kuchita izi pogwiritsa ntchito zida zapamwamba zoyezera kapena kuyang'ana kowonekera. Komanso, kupaka utoto kumathandizira kutsimikizira kuyatsa kosasintha. 

• Kufunika kwa Colour Binning

Zimatsimikizira kuti ma LED muzinthu zina ali ndi zofanana kutentha kwa mtundu (CCT). Komanso, Colour binning imapereka cholondola mtundu wopereka index (CRI). Izi zimapangitsa kuwala kwa ma LED kuti azigwirizana pamayunitsi onse. Ndipo mitundu ya zinthu imaimiridwa molondola. 

• Miyezo ya Colour Binning

Kuyika kwamtundu wa LED kumakhazikitsidwa ndi Chithunzi cha CIE 1931 Chromaticity (kuchokera ku International Commission on Illumination). Chithunzichi chili ndi ma quadrilaterals angapo omwe amawonetsa kusiyana kwa mawonekedwe a kuwala.

Mulingo wa CIE uwu umagawa kutentha kwamtundu wa LED m'magulu anayi. Izi ndi;

The Color Rendering Index (CRI) ndi Mtundu Wamtundu (CQS) Ndi miyeso ina yomwe imagwiritsidwa ntchito popanga utoto wa LED. CRI imayesa momwe gwero la kuwala limasinthira molondola mitundu ya kuwala kwa dzuwa. Panthawi imodzimodziyo, CQS imawerengera molondola momwe kuwala kumasonyezera kusiyana kwa mitundu. Ma LED abwino kwambiri ayenera kukhala ndi CRI osachepera 80, pomwe CQS osachepera 70.
