Sab nraud ntawm lub semiconductor diode, muaj ob peb lwm yam tseem ceeb ntawm LED uas yuav tsum tau ua kom nws ua haujlwm. Cov no muaj xws li cov leadframe ua los ntawm cov ncej thiab anvil, lub reflective kab noj hniav, hlau daim ntawv cog lus thiab epoxy lens los yog rooj plaub. Qee qhov kev tsim LED yuav suav nrog cov khoom ntxiv lossis muaj kev ua kom zoo ntxiv, tab sis txhua yam muaj cov ntsiab lus tseem ceeb no. Hauv qab no yog cov ncauj lus kom ntxaws ntawm txhua yam ntawm cov khoom no.
Leadframe - Sab nraum ntawm lub semiconductor tuag, leadframe yog lub plawv ntawm LED nti. Qhov no muaj xws li ib tug anvil, uas yog tsis zoo them thiab tuav cov khoom semiconductor nws tus kheej, thiab tus ncej, uas yog zoo them thiab muaj cov hlau daim ntawv cog lus uas muab tam sim no rau hauv lub tuag. Ob yam ntawm cov leadframe no tsis kov lub cev, thiab tsuas yog txuas nrog ntawm daim ntawv cog lus.
Reflective Cavity - Qhov no yog cov khoom siv hluav taws xob uas nyob ib puag ncig lub semiconductor tuag, coj txhua lub teeb tawm sab nraud ntawm lub lens. Nws feem ntau yog ntau zaus loj dua qhov tuag nws tus kheej.
Hlau Bond - Qhov no yog qhov me me ntawm cov hlau uas khiav los ntawm kev xa mus rau qhov chaw ntawm cov khoom siv hluav taws xob tuag, muab nws tam sim no.
Epoxy Lens / Case - Qhov no muab kev tiv thaiv thiab kev ruaj ntseg rau lub LED chav tsev, rigidly affixing tag nrho cov Cheebtsam nyob rau hauv qhov chaw. Nws muaj kev tiv thaiv kev tiv thaiv, nrog rau kev vibration tseem ceeb, uas yog qhov tseem ceeb rau kev lag luam lossis kev ua haujlwm siab.

Daim duab qhia txog cov khoom tseem ceeb ntawm LED diode
Txhua Lub Teeb-Emitting Diodes yog tsim los ntawm tib lub hauv paus ntsiab lus thiab cov khoom. Txawm li cas los xij, muaj qee qhov sib txawv tseem ceeb hauv kev tsim ntawm cov thev naus laus zis sib txawv, uas tau piav qhia hauv cov duab hauv qab no.
Standard Diode - Qhov no yog daim ntawv tseem ceeb tshaj plaws ntawm LED, thiab tseem yog qhov qub. Nws suav nrog lub voj voog ncaj nraim uas muaj lub pob tawb thiab ib qho ncej, nrog cov hlua khi hluav taws xob txuas tus ncej mus rau cov khoom siv semiconductor hauv lub dab teg. Tag nrho cov khoom no yog encased nyob rau hauv ib tug epoxy resin lens / vaj tse, nrog anode thiab cathode sib txuas npaj rau yooj yim soldering rau ib lub rooj tsavxwm.
SMD LED - Luv luv rau "Nto Mount Ntaus", cov LEDs no yog qhov tshwj xeeb hauv qhov uas tsis yog ib tus neeg qhov chaw uas tau siv los ntawm lub rooj tsavxwm, lawv tau muab tso rau hauv lub rooj tsavxwm nws tus kheej. Ib qho ntawm qhov zoo tshaj plaws ntawm qhov kev tsim no yog tias LED mount ua raws li lub dab dej kub, tso cai rau cov dej ntws ntau dua thiab ua haujlwm zoo dua, ua kom muaj lub teeb ntau dua.
COB LED - Sawv rau "Chip on Board", qhov no yog kev hloov pauv ntawm SMD tsim. Hauv qhov tsim no, LED nti tau txuas ncaj qha mus rau lub rooj tsav xwm Circuit Court siv thermal nplaum. Qhov no tso cai rau kev ua haujlwm ntxiv hauv kev ua kom txias, vim muaj kev sib cuag ncaj qha ntawm cov semiconductor tuag thiab lub rooj tsavxwm. Qhov nce hauv kev ua kom txias dua ntawm SMD tsim tso cai rau kev ua haujlwm ntau dua thiab ua haujlwm tau zoo.
