Dab tsi yog kev ceev faj rau siab - fais fab LED chips?
Lub siab -lub zog LED teeb hlaws OSLON SSL muaj zog, me me thiab ntev hauv kev pabcuam lub neej, ua tiav lub teeb pom kev zoo uas yuav tsum tau ua rau kev siv teeb pom kev zoo sab hauv tsev thiab sab nraum zoov. Nws txais cov pob ceramic thiab cov chips tshiab kawg, kev tiv thaiv corrosion thiab kev ntseeg siab, uas zoo kawg nkaus daws cov kev xav tau ntawm lub neej ntev - daim ntawv thov, haum rau kev lag luam teeb pom kev zoo thiab sab nraum zoov teeb pom kev zoo.
Nco tseg rau siab- lub zog coj teeb hlaws:
Nyob rau hauv cov txheej txheem ntawm high-cov khoom siv hluav taws xob LED thiab cov khoom siv hluav taws xob, hluav taws xob hluav taws xob, kev tiv thaiv electrostatic thiab vuam muaj kev cuam tshuam zoo rau lawv cov yam ntxwv, uas yuav tsum tau them nyiaj rau cov neeg siv khoom.
Kub dab dej
Vim muaj kev txwv ntawm semiconductor teeb-emitting diode nti tshuab, photoelectric conversion efficiency ntawm LEDs yuav tsum tau txhim kho, tshwj xeeb tshaj yog siab - fais fab LEDs. Vim nws lub zog siab, ntau dua 60 feem pua ntawm cov hluav taws xob hluav taws xob yuav raug tso tawm raws li lub zog hluav taws xob (nrog rau kev tsim cov tshuab semiconductor, photoelectric hloov dua siab tshiab yuav maj mam nce), uas yuav tsum tau ua haujlwm loj rau qhov kawg - cov neeg siv khoom .
1. Radiator yuav tsum.
Cov tsos mob thiab cov khoom siv: Yog tias cov kev cai sealing ntawm cov khoom tiav tsis siab, nws tuaj yeem ncaj qha convected nrog huab cua sab nraud. Ib qho finned aluminium los yog tooj liab kub dab dej yog pom zoo.
High-power LED teeb hlaws dai
2. Siv tau cov cua kub dissipation cheeb tsam:
Rau 1W siab-lub zog LED lub teeb dawb (lwm cov xim yeej ib txwm zoo ib yam), qhov pom zoo kom sov lub dab dej muaj qhov ua kom sov tau zoo dua li 50-60 square centimeters. Rau cov khoom siv 3W, nws raug pom zoo tias tag nrho thaj chaw ntawm lub dab dej kub yog ntau dua 150 square centimeters, thiab lub zog saib thiab cov txiaj ntsig tau zoo dua, thiab qhov kub ntawm lub dab dej kub tsis siab tshaj 60.
3. Txoj kev sib txuas:
Thaum lub siab {{0}} lub zog LED substrate txuas nrog lub dab dej kub, thov xyuas kom meej tias ob qhov chaw sib cuag yog du thiab zoo. Txhawm rau txhim kho qhov kev sib txuas ntawm ob qhov chaw sib cuag, nws raug nquahu kom siv cov txheej txheem thermal conductive silicone roj (cov thermal conductivity ntawm silicone roj ntau dua 3.0W / m K) ntawm qhov chaw ntawm LED substrate lossis cua sov. dab dej thiab cua sov nws. Lub conductivity ntawm silicone roj yuav tsum tau thov tusyees thiab tusyees, ces cov ntsia hlau yuav tsum tau compressed thiab ruaj ntseg.
Electrostatic tiv thaiv ntawm siab -lub zog LED teeb hlaws:
LED yog ib qho khoom siv semiconductor. Nws yog rhiab heev rau hluav taws xob static. Tshwj xeeb tshaj yog rau cov dawb, ntsuab, xiav thiab violet LEDs, peb xav tiv thaiv thiab tshem tawm cov hluav taws xob zoo li qub.
1. Cov hluav taws xob zoo li qub:
(1) Kev sib txhuam: Hauv lub neej niaj hnub, ob yam khoom sib txawv tuaj yeem sib cais tom qab kev sib cuag, thiab tom qab ntawd hluav taws xob zoo li qub raug tsim tawm. Txoj kev siv ntau tshaj plaws ntawm kev tsim hluav taws xob zoo li qub yog FRIC.
