LED Sawb Teeb Tsim Tau Li Cas? (Kauj Ruam 1-2)

Thawj kauj ruam: ob peb co me ntsis los tsimLED Sawb Teeb Pom Kev Zoo

Benwei Leds ua qee qhovQhov Zoo Tshaj Plaws Zoo Sawb TeebHauv ntiaj teb (thiab tawm ntiaj chaw, tam sim no hauv orbit) siv cov qauv hauv qab no. Peb tsis tau lees tias yuav ua raws li lwm cov kev tsim khoom lag luam lossis peb yuav ua yeeb yam rau lwm tus ua raws li peb li. Peb cia siab tias koj yog txhua tus tsis muaj qhov tsis zoo txog qhov ua tau zoo li peb yog thaum nws los txog koj cov haujlwm; Peb kuj ntseeg hauv kev qhia lub ntiaj teb hais txog qhov thev naus laus zis zoo kawg no!
Peb Benwei LEDs mus kom zoo yog condensed, nrog saib-cov kauj ruam tom ntej rau cov tshwj xeeb hauv qab no:
Txheeb thiab nkag siab txog koj cov khoom siv.
Thawj ib feem ntawm kev tswj kom zoo: qhuav lub leds
Qhov 2: Tswjhwm Zoo ua thiab thov cov jolder pwm
Diav coj-dawb tin ham satering muab tso rau hauv lub hauv paus. Pcb
Qhov thib peb feem ntawm kev tswj hwm zoo: Cheebtsam tso rau ntawm cov ntaub qhwv
Plaub Tswjhwm Tswj
Txhawm rau lav txhua yam, ci sawb hauv qhov cub refle.
Ntu 5 ntawm Kev Tswj Xyuas Zoo
Txheeb thiab tom qab ntawd sib sau ua ke 0. {{}} Meter sawb seem.
Feem rau: Kev Tswj Xyuas Zoo
Tus PCB lub nraub qaum tau txais daim kab xev rau nws.
Soldering kev sib txuas thiab hlau ua rau txhua lub sawb
Hlau cov ntsiab lus yog Hewbe shrinkable kua nplaum thov rau
Rau IP64 los ntawm IP68 ntawv pov thawj sawb teeb, waterproofing thiab huab cua chaw
Ntu 7 nyob rau kev sim ua hnub nyoog zoo
Txig dov mus rau ib tug reel
Tshooj Yim: Tswjhwm Zoo
Tuaj txog hauv lub tsev rau khoom; Sab Hauv Tsev Tswjhwm Zoo 9
Kaum ob kauj ruam kawg: Tswjhwm Zoo

Kauj ruam thib ob: Paub cov khoom siv ntawm kojLED Sawb

Pib nrog qhov zoo tshaj plaws cov khoom siv tau qhia, ntau npaum li nrog ntau cov khoom hwm. Nqis sij hawm sijhawm thiab kev rau siab xaiv cov ntu zoo tshaj plaws rau cov kab txaij. Txawm hais tias muaj nqi ntau dua li lwm cov khoom tsis zoo, lawv tsim nyog nws.
Thaum cov khoom siv no tau txais, tsim khoom tuaj yeem pib:

Cov ntawv luam tawm Circuit Court Board
Qhov zoo tshaj plaws conductivity thiab tshav kub dissipating ob-txheej Nco ntsoov, kub txo lub neej ntawm ib tug LED, yog li nws yog preferable kom tau tshem nws!

Feem ntau cov neeg tseem ceeb: SMD LEDs
Lub ci ci thiab fais fab siv ntawm cov kab txaij yuav txiav txim siab los ntawm tus coj koj xaiv. Tsis yog tsuas yog yuav tsum tau koj piv rau "coj ntau thiab tsawg". Ob 5050 Qhov loj tau coj los ntawm ib qho ob tuam ntxhab yuav ua thiab kawg me ntsis. Thov cov ntawv pov thawj thiab cov ntaub ntawv.
Cov ntawv xaiv tau muaj 99.99% cov xov hlau nyiaj, cov neeg tuag cov ntaub ntawv, phosphors, thiab cov thermal ntawm thermal ntaub. Xaiv cov LEDs kuaj hauv LM -80 thiab tm -21 Tshaj qhia uas tau pom zoo.
Lub peev xwm ntawm lub teeb sawb los ua kom zoo, ua kom pom tseeb ua rau nws muaj qhov tseem ceeb tshaj plaws. Tshawb xyuas cov kab txaij rau cov pob zeb siab, gamut Performance index, fouldation falence, thiab kev nyab xeeb.

Despors:
Yuam kev siv nrog LED rau pem hauv ntej voltage the resistor tus nqi yuav txawv batch tom qab batch. Tau txais cov neeg tsim khoom los ntawm cov chaw tsim khoom.
Cov khoom siv zoo kuj tseem ceeb heev vim tias skimping ntawm ntu no yuav ua rau koj lub teeb ci txaij kom tsis ntxov.
Sim tsis txhob overwhelm koj leds. Thaum xub thawj lawv yuav zoo li ci ntsa iab tab sis lawv yuav swb sai. Peb paub qee qhov ntawm peb cov kev sib tw uas siv txoj hauv kev no. Yog muab tso rau cov khoom siv hluav taws xob, cov cua sov ntxiv tuaj yeem muaj kev puas tsuaj.

UL cov kev sib txuas thiab cov cable.
Xaiv cov khoom siv tau txheeb xyuas rau qhov kav ntev thiab kev nyab xeeb. Hlau pheej yig tshwm sim zoo ib daim hlab kom tsis muaj txiaj ntsig.

Thermally ua cov ntaub nplaum nrog theej cov nyiaj sib txuas ntau
Peb siv VHB daim kab xev hauv 3m hom. Ntau tus neeg muag khoom muab bogus hom nplaum nplaum-tsis-npe lossis ua phem. Cov kab xev zoo yog qhov zais rau ob qho tib si thermal conductivity thiab ntev-ntev installation. Yog tias lub teeb sawb nyam ua tau ob peb lub hlis tom qab, nws zoo yog dab tsi?
