Kuthetha ntoni umgca wokukhanya we-smd?

Ngokuduma koyilo loyilo "akukho sibane sikhanyisayo sikhanyisayo", iimveliso zomtya wokukhanya we-LED ziya zithandwa ngakumbi kumhombiso wasekhaya kunye neeprojekthi zokwenza ngokwezifiso zendlu yonke. Kukho iimveliso ezintathu eziqhelekileyo zokukhanya okuguquguqukayo kwe-LED kwimarike, ezizezi, izibane ze-SMD ze-LED, izibane ze-COB ze-LED kunye nemicu yokukhanya ye-CSP ye-LED yamva nje. Nangona imveliso nganye ineengenelo kunye nokwahluka kwayo, umhleli uya kuzama ukusebenzisa inqaku elinye ukukuvumela ukuba uqonde umahluko phakathi kwezi zintathu, ukuze wenze ukhetho olufanelekileyo.

Imichilo yokukhanya ye-SMD, igama elipheleleyo leZixhobo eziNyunyiweyo zoMphezulu (iZixhobo eziFakelwe phezulu) imichilo yokukhanya, ibhekisa kwi-chip ye-LED ifakwe ngokuthe ngqo kwi-substrate yomgca wokukhanya, kwaye emva koko ipakishwe ukwenza imiqolo yamaso amancinci. Olu hlobo lomgca wokukhanya luhlobo oluqhelekileyo lwesibane sokukhanya kwe-LED, esihlala sineempawu zokuguquguquka, ukubhitya, ukonga amandla, kunye nobomi obude.

I-SMD sisishunqulelo se "Surface Mount Device", lolona hlobo luxhaphakileyo lwesixhobo se-LED okwangoku kwintengiso. I-chip ye-LED ifakwe kwigobolondo le-bracket ye-LED kunye neglue ye-phosphor kwaye emva koko ifakwe kwibhodi yesekethe eprintiweyo (PCB). Iintambo ze-SMD ze-LED zithandwa kakhulu ngenxa yokuguquguquka kwazo. , Izixhobo ze-LED ze-SMD ziza ngobukhulu obuhlukeneyo: 3528, 5050, 2835, 3014, 2216, 2110; ngokuqhelekileyo zibizwa ngokobukhulu bawo obusondeleyo, umzekelo, ubukhulu be-3528 yi-3.5 x 2.8mm, i-5050 yi-5.0 x 5.0mm, kunye ne-2835 yi-2.8 x 3.5mm, i-3014 yi-3.0 x 1.4mm.

Kuba izibane eziqhelekileyo ze-SMD ze-LED eziguquguqukayo zisebenzisa izinto ezahlukeneyo ze-SMD ze-LED, umgama / umsantsa phakathi kwezixhobo ezibini ezikufutshane ze-LED mkhulu kakhulu. Xa umgca wokukhanya ulayitiwe, unokubona amanqaku athile akhanyayo. Abanye abantu bathi Kwiindawo ezishushu okanye iimbalasane. Ke ukuba awufuni ukubona iindawo ezishushu okanye iindawo eziqaqambileyo, kuya kufuneka usebenzise imathiriyeli yokugquma (efana nesigqubuthelo seplastiki) ukuze uyibeke phezu komgca we-SMD we-LED, kwaye kufuneka ushiye ubude obaneleyo ukuze udibanise ukukhanya. iindawo ezibengezelayo Isiphumo sendawo eqaqambileyo, ngoko ke iiprofayili zealuminiyam ezidla ngokusetyenziswa zityebile.

Umgca wokukhanya we-COB, igama elipheleleyo yi-Chips kwiBhodi ye-LED strip yokukhanya, luhlobo lokukhanya kwe-LED kunye ne-chip kwi-package yebhodi (iiChips kwiBhodi). Xa kuthelekiswa nemigca yokukhanya ye-SMD, iintambo zokukhanya ze-COB zipakisha ngokuthe ngqo iitshiphusi ezininzi ze-LED kwibhodi yesekethe ukwenza indawo enkulu ekhupha ukukhanya, edla ngokusetyenziswa kwiimeko zesicelo ezifuna ukukhanya okufanayo.

Enkosi ngokuqhubekekayo kweglue ye-phosphor, imichilo ye-COB ye-LED inokuvelisa ukukhanya okufanayo ngaphandle kwendawo yokukhanya ecacileyo, ukuze ikhuphe ukukhanya okukhuphayo ngokulinganayo kunye nokungaguquguquki okuhle ngaphandle kwesidingo seplastiki ezongezelelweyo. , ukuba usafuna ukusebenzisa izitya ze-aluminiyam, unokukhetha iiprofayili ezibhityileyo ze-aluminium.

I-CSP yenye yeetekhnoloji zamva nje kushishino lwe-LED. Kwishishini le-LED, i-CSP ibhekisa kweyona fom incinci kwaye ilula yephakheji ngaphandle kwe-substrate okanye ucingo lwegolide. Ngokwahlukileyo kubuchwepheshe bebhodi yebhodi yokukhanya ye-SMD, i-CSP isebenzisa iibhodi zesekethe eziguquguqukayo ze-FPC.

I-FPC luhlobo olutsha lwentambo eyenziwe ngefilimu ekhuselayo kunye nocingo olucekeceke kakhulu oluthe tyaba lobhedu, olucinezelwe kunye ngomgca wokuvelisa izixhobo ezizimelayo. Ineenzuzo zokuthamba, ukugoba kwamahhala kunye nokugoba, ubukhulu obuncinci, ubungakanani obuncinci, ukuchaneka okuphezulu, kunye ne-conductivity enamandla.

Xa kuthelekiswa nokupakishwa kwe-SMD yendabuko, ukupakishwa kwe-CSP kunenkqubo elula, i-consumables encinci, ixabiso eliphantsi, kunye ne-angle yokukhupha ukukhanya kunye nolwalathiso lukhulu kakhulu kunezinye iifom zokupakisha. Ngenxa yobungcali benkqubo yokupakisha, imichilo yokukhanya ye-CSP inokuba ncinci, ibe khaphukhaphu kwaye ibe khaphukhaphu, kwaye ibe namanqaku amancinci okugoba. Ngelo xesha, i-angle yayo ekhupha ukukhanya inkulu, ifikelela kwi-160 °, kwaye umbala okhanyayo ucocekile kwaye uthambile, ngaphandle kwemiphetho ephuzi. Olona phawu lukhulu lwemigca yokukhanya ye-CSP kukuba ayiboni kukhanya kwaye ithambile kwaye ibuthuntu.
