Cuaj qhov tseem ceeb cuam tshuam rau tus nqi ntawm LED teeb hlaws

LED teeb hlaws yog cov khoom lag luam paub zoo hauv kev lag luam LED, tab sis ntau tus neeg tsis paub ntau txog tus nqi ntawm LED teeb hlaws. Dab tsi yog vim li cas rau tus nqi ntawm LED teeb? Koj tuaj yeem nkag siab meej meej. Cia peb saib ntawm qhov cuam tshuam ntawm tus nqi ntawm LED teeb hlaws. LED loj: txawv specifications ntawm LEDs nrog cov nqi sib txawv. Piv txwv li, 0603 LED thiab 1210, uas yog, 3528 LED, tus nqi yog loj; thiab tus nqi ntawm LEDs ntawm 1210 thiab 5050 yog txawv. Tsis txhob cia li xyuam xim rau tus nqi thaum yuav LED teeb hlaws dai. Kev ntsuam xyuas yuav tsum. Cov chips siv los ntawm LED teeb hlaws: chips suav nrog hauv tsev thiab Zhuhai chips thiab cov chips txawv teb chaws (xws li American chips, Japanese chips, German chips, thiab lwm yam). Cov nti sib txawv, tus nqi sib txawv heev. Tam sim no, cov chips kim tshaj plaws Asmeskas, ua raws li Japanese chips thiab German chips, tus nqi qis tshaj Zhuhai nti, cov cua kub dissipation kev ua tau zoo dua me ntsis. Dab tsi chip yog siv? Dab tsi yuav tsum ua tiav? Ua ntej yuav. LED ntim: resin ntim thiab ntim silicone. Tus nqi ntawm resin ntim yog pheej yig dua. Lwm tus yog tib yam. Kev ua haujlwm txias ntawm silicone ntim yog qhov zoo, yog li tus nqi yog me ntsis kim dua li cov ntim ntim. LED xim sib xws: tam sim no muaj ntau lub tsev ntim khoom hauv Suav teb. Muaj ntau txhiab tus loj thiab me me ntxiv, ntawm chav kawm, muaj lub zog ntawm lub zog thiab tsis muaj zog. Muaj ntau lub chaw ntim khoom me me vim tias tsis muaj qhov sib cais xim sib faib tshuab, yog li nws yog qhov txawv ntawm cov xim lossis xim, yog li nws nyuaj rau lav qhov zoo. Cov xim sib xws ntawm LED yam tsis muaj kev sib cais xim yog qhov tsis zoo, thiab cov nyhuv tom qab teeb pom kev zoo ntawm LED teeb hlaws tsis zoo, tau kawg, tus nqi sib txawv kuj loj. LED vuam nyhuv: Ob hom kev sib dhos thiab kev sib tsoo thiab tshuab vuam ntawm LED teeb hlaws. Kev tuav vuam yog siv cov hlau soldering thiab siv cov txheej txheem qub tshaj plaws rau vuam. Cov khoom uas nkag mus rau qhov kev ua haujlwm no yog qhov tsis zoo (cov khoom siv vuam tsis sib haum nrog qhov loj ntawm Fuzhou LED cov khoom siv hluav taws xob). Qhov thib ob yog tias kev ntsuas kev saib xyuas zoo li qub tsis zoo. Tshuab vuam yog welded nrog reflux vuam, thiab tshuab vuam yog txawv. Tsis tsuas yog cov khoom siv vuam zoo nkauj xwb (qhov loj ntawm cov vuam sib koom ua ke, cov vuam sib txuas du, qhov seem vuam seem, cov ntim LED tsis zoo), thiab yuav tsis muaj qhov tshwm sim ntawm cov nti raug hlawv los ntawm electrostatic thiab hlawv. Nyob rau tib lub sijhawm, LED txoj haujlwm thiab kev taw qhia zoo nkauj dua. Qhov no tuaj yeem pom ncaj qha los ntawm qhov tsos. FPC Khoom: FPC sib cais thiab ncua tooj liab thiab tooj liab. Nws yog pheej yig dua los thov cov phaj tooj liab, thiab nws kim dua. Lub ncoo ntawm lub phaj tooj liab yog ib qho yooj yim kom poob tawm thaum lub khoov yog khoov, tab sis cov crushing tooj liab yuav tsis. Yam khoom ntawm cov khoom siv yog nyob ntawm tus neeg muag khoom los txiav txim siab raws li qhov chaw siv. Puas yog FPC tau dhau daim ntawv pov thawj ib puag ncig thiab UL ntawv pov thawj? Puas muaj patent rau LED? Tsis muaj nqi tsawg. Tus nqi ntawm daim ntawv pov thawj thiab patent yog kim dua. LED brightness: txawv brightness ntawm LEDs txawv tus nqi. Tus nqi sib txawv ntawm qhov ci ci zoo tib yam thiab siab ci LED yog qhov sib txawv heev. Yog li ntawd, koj yuav tsum paub meej tias qhov ci ntsa iab uas koj xav tau thaum yuav, yog li koj tuaj yeem nrhiav koj tus kheej cov khoom kom raug. LED xim: txawv xim. Tus nqi sib txawv. Liab, ntsuab yog qhov nyuaj rau kev faib cov xim thiab xim tawg, yog li tus nqi siab dua tus nqi ntawm lwm cov xim; xim liab, daj, xiav thiab lwm yam xim yog yooj yim dua thiab zoo ib yam. Cov xim tshwj xeeb xws li ntshav thiab xim av vim yog xim xim, tus nqi yog qhov kim tshaj plaws.
