Yuav ua li cas tiv thaiv lub teeb tuag ntawm LED tawg-pov thawj teeb?
LED ntim cov tuam txhab thiab LED tawg-pov thawj teeb manufacturers yuav ntsib qhov tshwm sim ntawm LED tuag teeb. Raws li LED engineers, yuav ua li cas txheeb xyuas thiab daws cov teeb meem no?
Muaj ob lub laj thawj tseem ceeb rau LED tuag teeb:
1) Cov xau tam sim no ntawm LED loj dhau, ua rau PN kev sib tshuam ua tsis tiav, kom lub teeb ci LED tsis teeb. Qhov xwm txheej no feem ntau tsis cuam tshuam rau kev ua haujlwm ntawm lwm lub teeb LED.
2) Cov kev sib txuas sab hauv ntawm lub teeb LED raug txiav, ua rau tsis muaj qhov tam sim no dhau los ntawm LED thiab lub teeb tuag, uas yuav cuam tshuam rau kev ua haujlwm ib txwm ntawm lwm cov teeb ci LED.
Yuav ua li cas tiv thaiv LED tuag teeb?
Cov hluav taws xob zoo li qub yog qhov txaus ntshai heev rau cov teeb ci LED, vim tias hluav taws xob zoo li qub ua rau suav tsis txheeb cov khoom siv hluav taws xob, ua rau kev lag luam poob ntawm kaum tawm lab nyiaj.
Yog li ntawd, tiv thaiv hluav taws xob zoo li qub los ntawm kev puas tsuaj rau cov khoom siv hluav taws xob yog ib txoj haujlwm tseem ceeb hauv kev lag luam hluav taws xob. Kev lag luam hauv LED ntim thiab daim ntawv thov yuav tsum tsis txhob coj nws maj mam.
Ib qho teeb meem hauv ib qho kev sib txuas yuav ua rau LED puas tsuaj, ua rau LED kev ua haujlwm tsis zoo lossis tsis siv.
Peb paub tias qhov hluav taws xob zoo li qub ntawm tib neeg lub cev (ESD) tuaj yeem ncav cuag li 3, 000 volts, uas txaus los ua kom puas lub LED nti. Hauv LED ntim cov kab ntau lawm, nws kuj tseem ceeb heev seb qhov kev tiv thaiv hauv av ntawm ntau yam khoom ua tau raws li qhov yuav tsum tau ua. Feem ntau, qhov kev tiv thaiv hauv av yuav tsum yog 4 Ohm, thiab qee lub sijhawm nrog cov kev xav tau siab, cov av tiv thaiv yuav tsum ncav cuag tsawg dua lossis sib npaug li 2 ohms.
Qee lub tuam txhab siv phau ntawv soldering thiab siv 40-watt zoo tib yam soldering hlau. Qhov kub ntawm soldering tsis tuaj yeem tswj tau. Qhov kub ntawm cov hlau soldering yog siab tshaj 300-400 degree . Kub soldering kub heev kuj yuav ua rau tuag teeb. Lub expansion coefficient yog ob peb zaug siab dua, thiab cov kub kub hlau solder pob qij txha yuav rub lub solder pob qij txha sib nrug heev vim thermal expansion thiab contraction, uas ua rau ib tug tuag teeb tshwm sim.
