Vim li cas tus nqi ntawm LED npuas thiaj txawv?

Tsis ntev los no, cov vev xaib loj tau tshaj tawm cov nqi sib piv ntawm kaum sab saum toj LED teeb pom kev lag luam LED pob npuas teeb. Los ntawm kev sib piv, peb tuaj yeem pom tias LED pob teeb ntawm tib lub teeb, tab sis tus nqi sib txawv, xws li ib hom 7W pob npuas 48.9 yuan, tab sis Lwm hom tsuas xav tau 13.2 yuan, thiab tus nqi sib txawv yog ze li peb. sij hawm. Dab tsi yog vim li cas vim li cas tus nqi ntawm cov khoom parameter sib txawv heev? Hnub no, kuv yuav coj koj los qhia qhov txawv ntawm tus nqi sib txawv ntawm LED pob npuas teeb. 1. LED teeb hlaws Qhov sib txawv zoo LED teeb hlaws yog txawv heev, thiab ntau hom LED teeb hlaws kuj txawv heev. Ib yam li 2835 teeb hlaws, qee qhov tsuas xav tau tsawg dua 2 xees, tab sis qee qhov xav tau ntau dua 7 xees. Yuav kom ua raws li tus nqi qis, cov tuam ntxhab siv cov hlaws tsis zoo LED teeb hlaws. Xws li lub teeb hlaws feem ntau muaj teeb meem loj heev. Nws yog qhov pib scrapped rau ob peb lub hlis. 2. Tus nqi sib txawv ntawm PCB ntawm cov khoom sib txawv ntawm PCB kuj tseem loj heev. Piv txwv li, txhuas substrate yog hais txog 200-300 yuan ib square meter, FR4 yog hais txog 150-200 square meters, thiab qhov qis-kawg cardboard tsuas yog nqi kaum ob txhiab daus las ib square meter. Qhov tseeb, nws kuj yog aluminium substrate, tib yam yog FR4, thiab tus nqi sib txawv. Cov khoom sib txawv yuav muaj qhov sib txawv thermal conductivity. Kev siv cov duab los qhia yuav ua rau LED kub tsis tuaj yeem tawm mus, uas yuav cuam tshuam rau LED lub neej. 3. Cov khoom siv hluav taws xob sib txawv kuj sib txawv, thiab lub zog hloov pauv yog qhov loj tshaj plaws, thiab kev cuam tshuam ntawm tus nqi ntawm tag nrho cov khoom yog qhov loj tshaj plaws. Piv txwv li, tsuas yog ib lub thaiv yog xav tau los thaiv qhov hluav taws xob qhov hluav taws xob, thiab kev hloov hluav taws xob zoo dua yuav tsum muaj tsib lossis rau rau daim, thiab ntau tshaj kaum daim. Cov khoom siv hluav taws xob muaj kev cuam tshuam ntau dua rau qhov zoo ntawm LED qhov muag teev, thiab nws yog ib qho yooj yim ua tsis tau thaum lub sij hawm siv cov khoom siv hluav taws xob tsis zoo, xws li cov teeb tuag, cov foob pob hluav taws, thiab lwm yam. 4 Cov ntaub ntawv sib txawv yog cov qauv loj, thiab txawm tias cov khoom siv tib yam nqi sib txawv. Piv txwv li, cov qauv yas tsis tuaj yeem muab piv rau cov qauv hlau txhua. Cov khoom siv tib yam, tus nqi ntawm cov qauv pej xeem thiab cov qauv ntiag tug txawv ntau yam. Qhov zoo ntawm cov khoom siv kuj cuam tshuam rau lub tshav kub dissipation ntawm cov khoom, thiab nws muaj feem xyuam rau cov neeg siv kev nyab xeeb.
