Lub neej luv luv LED
Lub neej theoretical kev pab cuam ntawm LEDs ua los ntawm cov tuam txhab ib txwm muaj feem ntau txog 100, 000 teev. Niaj hnub no, ntau lub cim luminous tsis tau siv txaus rau ib xyoos, thiab LED modules tau hloov ntau zaus, uas tau coj teeb meem ntau thiab kev lag luam poob rau cov neeg siv khoom thiab cov neeg tsim khoom lag luam.
Kev daws: yuav tsim nyog ib leeg LED teeb pellets tsim los ntawm cov tuam txhab tsis tu ncua (qhov kev piav qhia tsis zoo los ntawm cov chaw tsim khoom yog xav tau), thiab ua cov modules los ntawm koj tus kheej. Tsis txhob sim yuav ib qho LED teeb pellet lossis ib qho tiav module hauv khw muag khoom hluav taws xob pheej yig. Yog tias koj xav yuav ib qho module, koj yuav tsum pom muaj pes tsawg tus resistors tau nruab rau ntawm lub module. Nws yog qhov zoo tshaj kom tsis txhob siv lub module nrog ib tug resistor. Lub resistor plays lub luag haujlwm txwv tam sim no hauv module, thiab nws yooj yim los tsim kom muaj cua sov. Tom qab lub sijhawm ntev ntawm kev siv tas mus li, thaum lub resistor raug hlawv tawm, qhov module no yuav tsis teeb. LED teeb feem ntau tsis tawg. Tsis txhob muab pov tseg lub module, tsuas yog hloov lub resistor nrog tib tus nqi kuj thiab nws tuaj yeem siv tau ib txwm. Qhov no tuaj yeem txuag nyiaj rau lub tsev tsim khoom. Txhawm rau txo cov teeb meem thiab txuag nyiaj, nws yog qhov zoo tshaj plaws los xaiv ib qho module nrog ob lub resistors ntsia. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum nkag siab txog cov chaw tsim khoom ntawm cov chaw muag khoom uas ua rau cov modules saib seb lawv puas siv cov khoom siv los tiv thaiv zoo li qub thaum ua cov modules. Yog tias tsis muaj qhov chaw tiv thaiv zoo li qub ntxiv, txawm tias qhov kev tiv thaiv tsis raug hlawv tawm hauv kev siv, LED teeb tau yooj yim puas los ntawm kev tawg.

Cov xim lwj sai heev
Cov xim ntawm cov cim tshiab luminous teeb tsa yog ntshiab thiab ci, thiab xim yog pom tseeb dimmed tom qab siv tsawg tshaj li ib xyoos. Nws yog qhov phem heev ua kom cov fonts liab thiab tsis liab, ntsuab thiab tsis ntsuab.
Kev daws: Kev nyab xeeb siv tam sim no ntawm LED teeb yog feem ntau 20 milliamperes. Yog tias tus nqi no dhau, txawm tias qhov ci ntsa iab yuav nce me ntsis, cov xim attenuation yuav nrawm dua. Yog li ntawd, thaum yuav ib qho kev sib sau ua ke LED module, nco ntsoov sim nws cov txiaj ntsig tam sim no. Qhov ci ntsa iab hauv qab 20 mA tsis txaus, thiab qhov ci ntsa iab saum 22 mA cuam tshuam rau lub neej ntawm LED thiab ua kom cov xim lwj.
Cov xim tsis sib xws, pom tseeb xim txawv
Feem ntau manifested nyob rau hauv lub loj luminous cim ua los ntawm ntshiab dawb LED. Thaum sib dhos, kev ua haujlwm ntawm ib qho module tsis pom tseeb. Tom qab tag nrho cov font tau sib sau ua ke, chromatic aberration yog pom tseeb. Tag nrho cov ntawv zoo li daim ntawv qhia, ib daim dawb, ib daim xiav, thiab ib daim daj.
Kev daws: Cov teeb ci dawb LED yuav tsum dhau lub teeb sib cais thiab xim sib cais ua ntej tawm hauv lub Hoobkas (lub teeb tawm los ntawm qee cov LEDs uas tsis tau dhau lub teeb sib cais thiab xim sib cais yog dawb huv, qee qhov xiav, thiab qee qhov daj), thiab cov spectrophotometer yog kim. Feem ntau, cov chaw tsim khoom me tsis muaj cov khoom siv zoo li no, yog li lub teeb dawb uas tsim los feem ntau tau txais los ntawm cov chaw tsim khoom loj rau lub teeb sib cais thiab xim sib cais. Txij li thaum nws tsis yog ib yam khoom ntawm peb tus kheej lub Hoobkas, kev sib cais lub teeb thiab xim sib cais yuav tsis ceev faj. Qee lub tsev me me tsuas yog tsis cais lub teeb thiab xim. Lawv feem ntau nyiam cov neeg siv khoom ntawm tus nqi qis. Yog li ntawd, thaum muas dawb LEDs, tsis txhob blindly sim pheej yig. Nco ntsoov yuav LED teeb-emitting raj ib leeg-particle teeb los yog modules ntawm tib lub chaw tsim tshuaj paus, batch, thiab xim tooj los ua tib batch ntawm luminous cim.

Tag nrho yog dheev tawm los yog tawm ntawm lub sijhawm
Tom qab siv rau ib lub sij hawm, cov cim luminous pib flicker nyob rau hauv ib feem los yog nyob rau hauv tag nrho cov font lub teeb qhov chaw, thiab lawv yuav tsis teeb txhua lub sij hawm kom txog thaum lawv tag nrho. Feem ntau ntawm lub teeb-emitting modules muag nyob rau hauv kev ua lag luam yog kev cob cog rua nrog patch cords. Nyob rau hauv txoj kev no, nws yog qhov yooj yim thiab ceev rau cov neeg tsim khoom tshaj tawm rau nruab lub teeb-emitting module. Txawm li cas los xij, qee qhov teeb meem tshiab kuj tshwm sim. Vim hais tias lub connector yog eroded los ntawm ya raws nyob rau hauv cov huab cua nyob rau hauv lub sij hawm ntev siv, nws yog ib qho yooj yim mus oxidize thiab ua rau cov neeg pluag kev sib cuag, uas ua rau ib feem los yog tag nrho cov circuits yuav tsum powered tawm instantaneously los yog tag nrho, ua rau lub teeb font tshwm sim los yog tsis. kaj.
Solution: a. Tsis xav tau kev txuas thaum ua lub module, txuas ncaj qha nrog tinned tooj liab hlau thiab ces solder nws khov kho nrog activated carbon solder. b. Siv dag agate los ua kom tag nrho cov hollow peb-dimensional luminous cim los cais cov kev sib cuag ntawm lub teeb ci thiab huab cua.
Lub zog tso zis font loj, thiab lub zog txuag thiab txuag hluav taws xob tsis pom tseeb
Kev daws: Sim siv LED teeb-emitting modules nyob rau hauv ib pawg ntawm tsib lub teeb, thiaj li hais tias tus naj npawb ntawm cov teeb tseem tsis hloov, thiab lub hwj chim yog txo los ntawm ob feem tsib.
