Saamayn intee le'eg ayuu hawlgalka heerkulka sare ku leeyahay soo-bandhigidda rasaasta?Isticmaalka sii kordhaya ee shaashadaha bandhiga LED-ka maanta, si loo kordhiyo faa'iidooyinka shaashadda, isticmaalayaashu waa inay leeyihiin faham gaar ah oo ku saabsan dayactirka shaashadda LED-ka.Hadday tahay muraayad gudaha ah ama laydh dibadda ah, kuleyl ayaa soo baxaya inta lagu jiro hawlgalka, kulaylka dhashaa wuxuu sababi doonaa in heerkulka muraayadda LED-ku kor u kaco.Laakin, ma ogtahay saamaynta ay hawlgalka heerkulka sare ku leeyahay muraayada ledhka?Aan ka hadalno shenzhen LED soo saaraha Tuosheng Optoelectronics.

Xaaladaha caadiga ah, bandhigyada LED-yada gudaha waxay dhaliyaan kuleyl yar sababtoo ah iftiin hooseeya waxayna si dabiici ah u baabi'in karaan.Si kastaba ha ahaatee, shaashadda LED-ka ee dibadda waxay dhalinaysaa kuleyl badan sababtoo ah dhalaalkeeda sare, waxayna u baahan tahay in lagu kala diro qaboojiyaha ama taageere axial ah.Maadaama muraayadda LED-ku ay tahay badeecad elektaroonig ah, kororka heerkulka ayaa saameyn doona iftiinka iftiinka ee muraayadaha nalalka LED-ka, taas oo yareyneysa waxtarka shaqada ee darawalka IC iyo soo gaabinaya nolosha adeegga ee bandhigga LED.

1. LED bandhigay fashilka wareegga furan: heerkulka shaqada ee bandhiga LED wuxuu ka sarreeyaa heerkulka culeyska ee chip, kaas oo si dhakhso ah u yareyn doona waxtarka iftiinka ee shaashadda elektaroonigga ah ee LED, wuxuu keenaa iftiinka iftiinka cad oo keena dhaawac;Bandhiga LED waxa uu inta badan ka samaysan yahay resin epoxy hufan.Baakadaha, haddii heerkulka isgoysku uu ka sarreeyo heerkulka kala-guurka ee wejiga adag (sida caadiga ah 125 ° C), walxaha baakadku waxay isu rogi doonaan caag iyo isku-dhafka ballaarinta kulaylka ayaa si xoog leh u kici doona, taasoo keentay fashilka wareegga furan ee bandhigga LED.Heerkulka xad-dhaafka ah wuxuu saameyn doonaa suuska iftiinka ee bandhigga LED.Nolosha bandhigga LED-ka waxaa ka muuqda iftiinkiisa iftiinka, taas oo ah, dhalaalku wuxuu noqon doonaa mid hooseeya oo hoos u dhigaya marxaladda waqtiga ilaa uu ka baxo.Heerkulka sare ayaa ah sababta ugu weyn ee hoos u dhigista iftiinka muraayadda LED-ka, waxayna soo gaabin doontaa nolosha muraayadda LED-ka.Iftiinka iftiinka ee noocyada kala duwan ee bandhigyada LED way ka duwan yihiin, sida caadiga ah soosaarayaasha Shenzhen LED waxay siin doonaan jaangooyooyin iftiin caadi ah.Hoos u dhigida qulqulka iftiinka ee shaashadda elektiroonigga ah ee LED ee ay sababtay heerkulka sare waa mid aan dib loo celin karin.

Iftiinka iftiimaya ka hor inta aan la soo celin karin iftiinka iftiinka ee bandhiga LED waxaa loo yaqaan "flux luminous farko" ee shaashadda elektiroonigga ah ee LED.

2. Heerkulka korodhka ayaa hoos u dhigi doona waxtarka iftiinka iftiinka LED-ka: heerkulka ayaa kor u kaca, xoojinta electrons iyo godadka ayaa kordha, farqiga bandowga ayaa hoos u dhacaya, dhaqdhaqaaqa elektarooniga ah ayaa hoos u dhacaya;heerkulku wuu kordhaa, electrons-ka ku jira si fiican ayaa hoos u dhigi doona godadka Suurtagalnimada dib-u-habaynta shucaaca waxay keenaysaa dib-u-habayn aan shucaac ahayn (kuleyl), taas oo hoos u dhigaysa waxtarka gudaha gudaha ee bandhigga LED;Heerkulka korodhay wuxuu keenaa in buluugga ugu sarreeya ee chip uu u dhaqaaqo jihada mawjadda dheer, taasoo keenaysa hirarka sii daaya dhererka dhererka chip inuu ku daro fosfoorka.Isku-dheelli-tir la'aanta hirarka kacsanaanta waxay sidoo kale sababi doontaa waxtarka soo-saarka iftiinka dibadda ee bandhigga LED-ka inuu hoos u dhaco.Shaashadda: Marka uu heerkulku kor u kaco, waxtarka quantum ee fosfooraska ayaa hoos u dhacaya, qadarka iftiinka soo baxaya ayaa hoos u dhacaya, iyo waxtarka soo saarista iftiinka dibadda ee bandhiga LED ayaa hoos u dhacaya.Waxqabadka jel silica ayaa aad u saameeya heerkulka deegaanka.Marka heerkulku kordho, diiqada kulaylka gudaha jelka silica ayaa kordheysa, taasoo keenta in index refractive ee jel silica ay hoos u dhacdo, taas oo saameynaysa waxtarka iftiinka ee bandhigga LED.
