Raws li qhov chaw teeb pom kev tshiab tshiab, LED fais fab mov thiab tsav Circuit Court sib txawv ntawm cov hluav taws xob ballasts ntawm teeb roj fluorescent. Lub luag haujlwm tseem ceeb ntawm kev tsav tsheb ntawm kev tsav tsheb ntawm LED yog los hloov AC voltage rau DC voltage, thiab tib lub sijhawm ua tiav kev sib txuam nrog cov LED hluav taws xob thiab tam sim no. Nrog rau txoj kab poob ntawm silicon sib xyaw ua ke Circuit Court fais fab mov voltage, LED kev khiav hauj lwm voltage yog nce nyob rau hauv qhov zoo ntawm cov hluav taws xob cov zis hluav taws xob, thiab feem ntau ntawm cov thev naus laus zis rau hluav taws xob hluav taws xob tsawg ICs kuj tsim nyog rau lub hwj chim LEDs, tshwj xeeb tshaj yog cov hluav taws xob muaj zog LED. Cov. Cov. Tsis tas li ntawd, lub zog LED hluav taws xob yuav tsum tseem tuaj yeem ua kom tau txais txiaj ntsig ntawm kev lag luam ntawm kev lag luam los ntawm kev coj los ntawm kev nce zuj zus ntawm qhov hluav taws xob tsawg hluav taws xob IC ntau lawm.
Ib qho, lub ntsiab txheej txheem kev qhia ntawm LED fais fab mov thiab tsav Circuit Court
1) Voltage hloov dua siab tshiab tshuab
Lub hwj chim muab hluav taws xob yog ib qho tseem ceeb uas cuam tshuam kev cia siab thiab hloov kho ntawm cov teeb ci LED thiab yuav tsum txiav txim siab. Tam sim no, cov hluav taws xob tseem ceeb hauv peb lub teb chaws yog 220V hloov hluav taws xob tam sim no, thiab cov hluav taws xob LED yog qhov hluav taws xob semiconductor qhov chaw, uas feem ntau siv los ntawm kev siv hluav taws xob tsawg. Qhov no yuav tsum muaj AC-DC hloov mus rau hauv lossis sab nraud ntawm cov teeb no hloov kho kom haum rau cov yam ntxwv ntawm tus tsav tsheb LED tam sim no. Tam sim no, muaj ntau txoj hauv kev ntawm kev xaiv fais fab kev xaiv, xws li hloov hluav taws xob mov, kev siv hluav taws xob ntau, thiab kho cov hluav taws xob tom qab capacitor kauj ruam. Cov kev xaiv sib txawv tau ua raws li qhov sib txawv ntawm kev nyab xeeb tam sim no, kev hloov pauv ntev dua, kev nyab xeeb thiab kev cia siab.
2) Lub neej thiab tus nqi ntawm lub zog hluav taws xob thiab tsav Circuit Court
Hais txog kev ua lub neej LED, txawm hais tias lub sijhawm siv ntawm ib qho LED tau ntev npaum li 100,000 teev, nws daim ntawv thov yuav tsum tau nruab nrog lub zog hloov hluav taws xob, yog li lub neej tag nrho ntawm LED teeb pom kev zoo yuav tsum tau txiav txim siab los ntawm kev siv photoelectric kev sib xyaw. Tab sis rau cov teeb pom kev zoo ntawm LED, txhawm rau kom ua tau raws li qhov yuav tsum tau ua, lub neej ntawm kev siv hluav taws xob thiab tsav hluav taws xob yuav tsum muaj ntau tshaj 100,000 teev, kom nws tsis ua ib qho kev tsis pom nyob rau hauv kev teeb pom kev zoo ntawm LED. Thaum tseem xav txog lub neej ntev, nws tsis tas yuav nce tus nqi ntau dhau. Lub neej thiab nqi ntawm kev pabcuam hluav taws xob thiab tsav Circuit Court yuav tsum tsis pub ntau tshaj li ib feem peb ntawm tag nrho cov nqi ntawm cov teeb pom kev zoo. Hauv ntu thaum ntxov ntawm kev txhim kho ntawm cov teeb pom kev zoo ntawm LED khoom, nws yog qhov yuav tsum tau sib npaug ntawm lub zog hluav taws xob thiab cov nqi. Cov kev sib raug zoo ntawm lub neej ntawm tsav Circuit Court thiab ntawm tus nqi.
3) Programmable thev naus laus zis ntawm kev tsav tsheb
Qhov tseem ceeb tseem ceeb ntawm LED siv los ua lub teeb ci yog tias nws tseem tuaj yeem tswj tau nws qhov lumen efficiency nyob rau hauv qis tsav tsheb tam sim no. Nyob rau tib lub sijhawm, rau RGB polycrystalline lub teeb sib xyaw los tsim lub teeb dawb, los ntawm kev tsim cov digital RGB hybrid tswj kev tswj hwm rau LEDs, Cov neeg siv tuaj yeem hloov kho qhov ci, xim thiab cov hue ntawm LEDs nyob rau ntau qhov, muab cov neeg tshiab pom kev lom zem tshiab. Cov. Hauv daim ntawv thov ntawm lub nroog cov toj roob hauv pes teeb pom kev zoo, LED lub teeb pom kev tuaj yeem hloov pauv hauv cov qauv sib txawv hauv qab tswj hwm ntawm microprocessor los tsim cov txiaj ntsig zoo ntawm ntau yam qauv thaum hmo ntuj. Hauv kev hwm no, nws yuav cuam tshuam qhov tsis txawv ntawm LED tus txheeb ze rau lwm cov khoom siv hluav taws xob. Kev sib tw zoo dua.
4) Qhov ua tau zoo ntawm lub zog hluav taws xob thiab tsav Circuit Court
Cov hluav taws xob LED fais fab thiab tsav Circuit Court yuav tsum muaj qee yam rau tam sim no cov zis ze rau qhov hluav taws xob tas mus li yuav tsum tau los ntawm LED, tab sis kuj muaj qhov hloov pauv hloov dua siab tshiab. Kev hloov pauv ntawm electro-optical yog qhov tseem ceeb rau LED teeb pom kev zoo, txwv tsis pub lub LED yuav ploj Nrog qhov zoo ntawm lub zog txuag, kev ua haujlwm ntawm kev lag luam tam sim no hloov mus rau cov fais fab yog li 80%. Raws li lub zog hluav taws xob rau LED teeb pom kev zoo, nws cov kev hloov pauv hloov tseem xav tau kev txhim kho ntxiv.
Qhov ob, txuj ci kev tsim kho tshuab
1) Tsim cov hluav taws xob tsis tu ncua thiab tsis tu ncua tam sim no tswj hluav taws xob hluav taws xob raws li cov yam ntxwv ntawm LED, siv cov cuab yeej sib xyaw ntawm Circuit Court los tswj cov tswv yim ntawm txhua LED ntawm qhov zoo tshaj tus nqi tam sim no, kom lub LED tuaj yeem tau txais tam sim no ruaj khov thiab tsim qhov tso zis ntau tshaj plaws luminous flux. Lub tshuab tsav hluav taws xob hauv LED yog qhov zoo tshaj plaws los tswj lub LED tam sim no thaum cov input voltage thiab ambient kub hloov.
2) Lub tsav tsav hluav taws xob LED muaj qhov ntse tswj kev ua haujlwm, kom lub load tam sim no ntawm LED tuaj yeem tswj tau ntawm theem ua ntej hauv qab ntawm tus yam ntxwv ntawm ntau yam. Thaum lub load tam sim no hloov vim muaj ntau yam, thawj qhov kev tswj hwm IC tuaj yeem tswj tus hloov mus rov qab mus rau lub ntsaws rau tam sim no mus rau tus nqi pib tsim.
3) Hais txog kev tswj Circuit Court tsim qauv, nws yog qhov tsim nyog los tsim hauv peb qho: kev tswj hauv nruab nrab, kev hloov kho qauv, thiab kho qhov system.
4) Nyob rau hauv qhov xwm txheej tam sim no ntawm kev siv hluav taws xob tsawg LED luminous efficiency thiab luminous flux, muab kev ua si tag nrho rau cov yam ntxwv ntawm LED ntau haiv neeg xim, thiab txhim kho xim-hloov LED teeb pom kev zoo tswj Circuit Court.
