Nyob rau hauv lub teeb pom kev zoo retrofit tej yaam num rau chaw ua hauj lwm, supermarkets, factories, thiab underground chaw nres tsheb,T8 LED tubesyog cov feem ntau hloov rau cov tsoos fluorescent raj. Thaum lub sijhawm npaj pib, cov neeg yuav khoom feem ntau thov kom muaj peev xwm dimming- tso cai rau kev tswj tau yooj yim ntawm kev teeb pom kev zoo raws li lub sijhawm ntawm hnub kom ua tiav kev txuag hluav taws xob thiab kev tswj hwm huab cua. Txawm li cas los xij, ntau tus pom tsuas yog thaum lub sijhawm teeb tsa uas cov T8 yuav khoom tsis txhawb kev dimming, ua rau txoj haujlwm qeeb thiab siv nyiaj siv tsis tau.
Ib qho kev xav tsis zoo yog tias tag nrho T8 LED raj txhawb kev dimming. Qhov no tsis yog li ntawd; dimming muaj peev xwm nyob ntawm lub raj tus tsav tsheb sab hauv tsim thiab muaj cov yam ntxwv xws li ballast compatibility thiab thaiv txoj kev. Kab lus no piav qhia txog qhov tseem ceeb ntawm T8 LED raj dimming, qhia meej txog cov teeb meem feem ntau hais txog kev xaiv thiab kev teeb tsa, thiab pab koj kom tsis txhob muaj qhov cuam tshuam txog qhov project.
Puas yog tag nrho T8 LED raj txhawb dimming?
Tsis yog. Feem ntau ntawm cov qauv T8 LED raj ntawm kev ua lag luam yog nruab nrog cov yam ntxwv tas li -tam sim no, tsis yog - tsav tsheb dimmable; lawv yog lub Hoobkas- teeb tsa rau qhov tso tawm kom pom tseeb thiab tsis muaj peev xwm dimming. Txawm hais tias ua ke nrog lub dimmer hloov, cov teeb meem xws li flickering, jittering, los yog tsis tuaj yeem kho qhov ci tuaj yeem tshwm sim.
Tsuas yog T8 LED raj tshwj xeeb nruab nrog cov tsav tsheb dimmable tuaj yeem ua tiav qhov ci ci. Tshwj tsis yog tias qhov yuav tsum tau muaj qhov dimming tau hais meej meej thaum tso qhov kev txiav txim, cov tuam txhab feem ntau muab cov qauv uas tsis yog -dimmable version. Tsis tas li ntawd, cov kab hluav taws xob yuav tsum tau paub qhov txawv: ib qho - kawg thiab ob npaug -kawg wired tubes yuav tsum muaj cov tswv yim sib txawv rau kev rov ua dua tshiab, yog li cov khoom siv hluav taws xob uas twb muaj lawm yuav tsum tau kuaj xyuas ua ntej.
Mainstream dimming hom rau dimmable T8 LED raj
Peb qhov kev daws teeb meem dimming tam sim no muaj nyob rau hauv cov haujlwm lag luam, txhua qhov tsim nyog rau cov kev xav tau sib txawv:
Triac Dimming
Haum rau me me - nplai sab hauv tsev retrofits; nws txuas ncaj qha nrog Triac dimmer keyboards, ua rau cov txheej txheem retrofit yooj yim. Cov lus ceeb toom tseem ceeb: Yog tias cov khoom siv uas twb muaj lawm tau nruab nrog lub tshuab hluav taws xob, lub ballast feem ntau yuav tsum tau muab tshem tawm kom lub raj tuaj yeem txuas ncaj qha rau lub zog hluav taws xob.
0-10V Dimming
Qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm teeb pom kev zoo hauv cov tsev ua haujlwm loj thiab cov khw muag khoom. Nws tso cai rau kev tswj hwm hauv nruab nrab, kev sib koom ua ke ntawm cov kav hlau ntau, muaj kev dimming du thiab zoo heev flicker tswj, thiab yog qhov zoo tagnrho rau qhov loj - thaj tsam, kev tswj hwm teeb pom kev zoo. Teeb pom kev zoo thiab dimming controllers yuav tsum tau sib xws; cov khoom siv cov txheej txheem sib txawv tsis tuaj yeem sib xyaw.
DALI Digital Dimming
Siv nyob rau hauv siab - cov tsev ntse kawg thiab cov chaw lag luam zoo tshaj. Nws txhawb pab pawg tswj kev ywj pheej thiab kev teeb tsa ntawm ntau lub teeb pom kev zoo; nws muaj qhov dimming precision thiab ruaj khov, ua rau nws zoo tagnrho rau siab -tus qauv teeb pom kev zoo.
Installation thiab Compatibility Considerations rau Dimmable T8 Tubes
Ua ntej, ua ntej kom paub meej txog qhov kev npaj rov qab rau cov khoom siv uas twb muaj lawm. Feem ntau cov tsoos fluorescent hluav taws xob ballasts tsis sib haum nrog dimmable LED raj; rau feem ntau cov haujlwm, nws raug nquahu kom tshem tawm cov ballast thiab xaim lub raj ncaj qha mus rau lub zog hluav taws xob kom txo qis kev cuam tshuam.
Thib ob, siv tib tus qauv ntawm dimmable T8 raj hla ib lub voj voog ib zaug thaum twg ua tau. Kev sib xyaw dimmable thiab tsis yog - cov raj dimmable feem ntau ua rau muaj teeb meem xws li flickering lossis fixture malfunction.
Thib peb, xyuam xim rau kev txwv kev thauj khoom. Ob qhov dimming tsav tsheb thiab dimming keyboards muaj lub zog siab tshaj plaws; tus naj npawb ntawm cov raj txuas rau hauv ib lub koob yuav tsum tsis pub tshaj qhov ntsuas load.
Plaub, paub qhov txawv ntawm ballast- cov qauv sib xws thiab ncaj qha - qauv tsav. Txawm hais tias qee qhov dimmable T8 raj txhawb nqa ballasts uas twb muaj lawm, cov kev xaiv raug txwv; ib txwm txheeb xyuas kev sib raug zoo nrog tus neeg muag khoom ua ntej kev yuav khoom.
Teeb meem Dimming Feem ntau thiab ua rau
Qhov teeb meem 1: Nruam flickering thaum dimming
Feem ntau ua rau: tsis sib haum ntawm tus neeg tsav tsheb thiab cov txheej txheem dimming, lossis teeb liab cuam tshuam los ntawm kev tsis tshem cov hluav taws xob qub qub.
Qhov teeb meem 2: Tsis muaj peev xwm dim mus rau theem qis heev (qhov tsawg kawg nkaus ci hauv pem teb)
Economical dimmable tsav tsheb feem ntau muaj qhov tsawg kawg nkaus brightness pib; siab -kawg tsav tsheb yuav tsum muaj rau ntau yam ntawm du (stepless) dimming.
Qhov teeb meem 3: Tsis sib xws brightness thoob cov raj
Qhov hluav taws xob poob qis, xoob xaim, thiab kev siv cov qauv sib xyaw ua ke yog thawj qhov ua rau lub teeb ci tsis sib xws.
Cov ntsiab lus
Hauv luv luv: T8 LED tubes tsis muaj peev xwm dimming; dimming functionality nyob ntawm tus qauv tshwj xeeb ntawm lub built- nyob rau hauv tsav.
Yog hais tias ib qhov project yuav tsum tau kho brightness, lub dimmable version yuav tsum tau qhia meej meej thaum lub sij hawm yuav khoom. Tsis tas li ntawd, cov txheej txheem dimming tshwj xeeb-xws li Triac, 0-10V, lossis DALI- yuav tsum raug xaiv, thiab cov kev tswj hwm yuav tsum tau teeb tsa. Standard T8 raj tsis tuaj yeem rov kho dua rau qhov dimming tom qab; hom raug yuav tsum raug xaiv thaum pib. Rau qhov chaw uas tsis tas yuav hloov teeb pom kev zoo-xws li cov tsev khaws khoom thiab cov chaw ua haujlwm txheem- xaiv cov qauv, tsis yog{11}} cov raj dimmable pab tswj cov nqi. Hloov pauv, rau ib puag ncig uas xav tau kev tswj lub teeb pom kev zoo- xws li cov tsev ua haujlwm, cov khw muag khoom, thiab cov tsev ntse-cov kws tshaj lij dimmable T8 LED raj yog qhov kev xaiv tseem ceeb.
Puas yog koj tam sim no ua lub teeb pom kev zoo rov qab thiab nrhiav cov lus qhia tshwj xeeb, cov lus qhia txuas, thiab cov nqi ntau rau dimmable T8 LED raj?
Peb muab ntau yam ntawm ib qho - xaus thiab ob npaug - xaus T8 LED raj, muaj nyob rau hauv non-dimmable, Triac, 0-10V, thiab DALI versions, nrog rau ntau yam xim kub xaiv. Peb tuaj yeem muab cov kev daws teeb meem zoo raws li koj cov khoom siv uas twb muaj lawm; thov hu rau peb kom tau txais kev pom zoo cov khoom lag luam thiab cov nqi tshwj xeeb.
