Dab tsi yog vim li cas vim li cas lub zog siab LED nti tsis teeb?
Philips Lumileds imitation lumen LED hom imitation hom LED pob zoo yog deb tshaj qhov qub, LED vuam PCB pawg thawj coj saib lub teeb emission yog perpendicular rau PCB vuam board mus rau tib lub PCB LED hu ua sab-emitting LED.
Yog vim li cas vim li cas cov imitation lumen LED teeb hlaws tsis ci yog:
Lub imitation lumen LED yog txawv ntawm 2835 teeb hlaws. Lub imitation lumen yog txheej txheem ntim, thiab 2835 lub teeb hlaws yog txheej txheem thaj. Lub teeb nyhuv ntawm imitation lumen yog siab dua li ntawm thaj, thiab thaj yog yooj yim dua. , high efficiency, lwm yam tseem ceeb heev yog hais tias lub thaj yog heev npaum nyob rau hauv ntau lawm, tus nqi kuj tsawg, thiab ntau lawm efficiency ntawm imitation lumens kuj tsawg.
Anti-lumen LED
1. Thov xyuas seb cov kev sib cuag ntawm lub bracket yog oxidized thiab qhib Circuit Court
2. Kuv tsis paub' tsis paub dab tsi cov ntawv thawj yog raws li" Khoom siv lead ua tsev cog khoom hlau tsis zoo". Thov paub meej tias lub ncoo txoj hauj lwm ntawm cov hlau kub ntawm LED nti yog misaligned los yog ploj lawm, thiab tseem xyuas seb lub xov tooj kub puas nyob ntawm cov hlau bracket. Ib daim ntawv hlau zoo tsis yog soldered rau oxide txheej.
Vim hais tias cov qauv pob LED yog qhov yooj yim heev, yog tias cov hlua khi tuag tiag tiag, cov nti tuaj yeem teeb, ces lub pob tuaj yeem teeb. Thov nco ntsoov tias txoj hlua khi tuag tsis yog' zoo zoo' tab sis zoo heev.
LED anti-lumen teeb hlaws yog reflow soldered los yog tes soldered
Tom qab reflow soldering, vim hais tias lub dab dej kub yog soldered rau PCB, lub thermal kuj yuav me me, thiab cov thermal conductivity yog zoo dua. Yuav tsum muaj qee qhov thermal conductive silica gel hauv qab phau ntawv soldering, uas yog qhov nyuaj los xyuas kom meej qhov sib xws, qee zaum ntau dua, qee zaum tsawg dua Thiab cov thermal conductivity yuav twv yuav raug tsis ncaj qha rau ntawm PCB. Nyob rau lub sijhawm luv luv, silica gel tseem tuaj yeem siv tau, tab sis tom qab lub sijhawm ntev, cov thermal conductivity ntawm silica gel yuav raug txo kom tsawg.
Vim yog tus nqi ntawm cov cuab yeej siv, feem ntau cov chaw tsim khoom me me yog siv tes soldering, thiab cov chaw tsim khoom loj feem ntau yog reflowed. Tsis tas li ntawd, muaj ntau 1W teeb hlaws dai uas ua raws li lumens ntawm kev ua lag luam tam sim no, thiab cov hlaws teeb ntawm ntau lub Hoobkas yuav tsum tau rov ua dua nrog qhov kub thiab txias. Tom qab reflow soldering, lub luminous flux yuav txo qis me ntsis, feem ntau vim tias qhov kub thiab txias muaj qee yam cuam tshuam rau lub lens, tab sis reflow soldering nrog kub kub solder paste yuav zoo dua.
