T8 LED Tube Lub teeb: Tsim Cov Ntsiab Cai, Cov Txheej Txheem Xaiv & Kev Ua Haujlwm Zoo

Raws li qhov thib plaub - tiam teeb pom kev zoo, LED tau hloov pauv kev lag luam teeb pom kev zoo, thiab T8 LED raj lub teeb sawv tawm raws li kev paub tab thiab siv dav. Nyob rau hauv lub ntiaj teb no tsis muaj zog txaus thiab lub phasing tawm ntawm incandescent thiab fluorescent teeb, lub T8 LED raj lub teeb tau los ua qhov nyiam hloov vim nws lub zog efficiency, ntev lifespan, thiab ib puag ncig tus phooj ywg. Los ntawm 2010, LEDs twb suav txog 16% ntawm lub ntiaj teb teeb pom kev lag luam, nrog kev kwv yees qhia tias ntau tshaj ib nrab ntawm cov teeb pom kev zoo thiab cov teeb fluorescent hauv Asmeskas yuav raug hloov los ntawm LEDs, tsim kom muaj $ 50 billion kev lag luam. Kab lus no ua raws li EEAT txoj cai, sib koom ua ke cov ntaub ntawv tsim qauv, kev tshuaj xyuas cov khoom, thiab cov ntaub ntawv siv tau los tshawb txog cov qauv tsim qauv, kev xaiv cov ntsiab lus tseem ceeb, thiab cov tswv yim kev ua tau zoo ntawm T8 LED raj teeb. Nws muab kev pom zoo rau cov tsim teeb pom kev zoo, cov chaw tsim khoom, thiab cov kws tshaj lij kev muag khoom, txhawb nqa los ntawm kev qhia tshwj xeeb thiab kev tshawb fawb kev lag luam.

Dab tsi yog Cov Ntsiab Cai Tsim Nyog ntawmT8 LED Tube Lub teeb?

Tus tsim ntawm T8 LED raj lub teeb yog ib txheej txheem engineering uas ua ke nrog cov khoom siv kho qhov muag, hluav taws xob, thiab cov qauv kev xav. Cov hauv paus ntsiab lus tseem ceeb suav nrog ntsuas qhov ua tau zoo ntawm kev siv hluav taws xob thiab kev siv hluav taws xob, ua kom cov cua sov ua kom zoo, txo qhov ci ntsa iab, thiab ua kom muaj kev sib raug zoo nrog cov khoom siv uas twb muaj lawm- txhua yam uas qhia txog kev xaiv thiab kev sib dhos.

Sib npaug Luminous Efficacy thiab Energy Consumption

Lub hom phiaj tseem ceeb ntawmT8 LED tube teebtsim yog kom ua tiav siab luminous flux thaum txo hwj chim kos. Qhov no yuav tsum tau ceev faj xaiv ntawm LED chips, tsav tsheb circuits, thiab optical systems. Piv txwv li, 1200mm T8 LED raj teeb tsim kom haum rau 1400lm tso zis ntawm 40W fluorescent raj feem ntau siv 288 qis- fais fab LED chips (6.5lm txhua) teeb tsa hauv 24-series, 12-parallel configuration. Qhov kev teeb tsa no ua kom tag nrho cov luminous flux tsawg kawg yog 1450lm (sau rau 10-20% lub teeb poob los ntawm lub plhaub plhaub) thaum siv 18W-xa 70% kev txuag hluav taws xob piv rau cov raj fluorescent.

Tsawg- fais fab LED chips (tsawg dua lossis sib npaug li 0.1W) yog qhov nyiam rauT8 LED tube teebvim lawv cov kev ua tau zoo dua luminous (100-130lm/W) thiab qis dua cov hluav taws xob hluav taws xob ntau dua li siab dua- lub zog hloov. Lawv qhov loj me me kuj ua rau qhov chaw tsis sib xws, txo qhov ci ntsa iab thiab txhim kho lub teeb faib. Tus tsav tsheb Circuit Court yog ib qho tseem ceeb: tsis yog - cais cov tsav tsheb tsis tu ncua (xws li, raws li QX9910 nti) muab kev ua haujlwm siab (txog 93%), qhov loj me, thiab cov zis tam sim no ruaj khov, hloov AC zog (180V-265V) rau DC lub zog rau kev ua haujlwm zoo ntawm LED.

Optimizing Thaum tshav kub kub Dissipation

Excessive heat (junction temperature >85 degree) tuaj yeem txo qis kev ua haujlwm ntawm LED, ua kom lub teeb tawg, thiab ua kom lub neej luv. T8 LED raj lub teeb tsim nyob qhov no los ntawm kev xaiv cov qauv thiab cov khoom siv. Rau qis-faiv fab LED teeb tsa, cov ntawv luam tawm Circuit Board (PCB) thiab lub plhaub raj ua haujlwm ua cov txheej txheem ua kom sov. Epoxy iav ntaub PCBs (1.2mm thickness, 35μm tooj liab ntawv ci) muab txhua yam kev txhawb nqa thiab ua kom sov los ntawm LED chips mus rau lub plhaub raj. Lub plhaub plhaub, feem ntau yog ua los ntawm cov nplaim hluav taws-retardant PC lossis aluminium-plastic composite, dissipates tshav kub ntawm natural convection.

Kev kuaj pom tseeb tias aT8 LED tube teebnrog rau tag nrho - lub plhaub yas thiab qis - lub zog LEDs pom qhov kub nce ntawm tsuas yog 21.5K tom qab 4 teev ntawm kev ua haujlwm ntawm 23.5℃qhov kub thiab txias. Qhov no ua rau LED tus pin kub hauv qab 65 degree, tsis ncaj qha kom ntseeg tau tias cov nti sib txuas qhov kub nyob hauv qhov kev txwv tsis pub dhau 85 degree. Rau siab -lub zog lossis SMD LED teeb tsa, aluminium- cov raj yas nrog aluminium backplates txhim kho cov cua sov los ntawm kev sib txuas ncaj qha rau aluminium substrate rau lub raj aluminium txheej.

Minimizing Glare thiab txhim kho lub teeb faib

Tsis zoo li cov raj fluorescent, uas emit lub teeb 360 degree, LEDs muaj kev taw qhia emission, ua rau muaj peev xwm ci ntsa iab thiab tsis sib xws lub teeb. T8 LED raj lub teeb tsim mitigates qhov no los ntawm optical optimization. Lub plhaub lub plhaub diffuser yog ib qho tseem ceeb: diffusion npog (nrog rau cov diffusers ntxiv) los yog striped npog tawg lub teeb kom nthuav dav beam lub kaum sab xis, thaum lub npog pob tshab tsis tshua siv vim qhov muag pom kev hnyav.

Kev ntsuam xyuas qhia tau hais tias diffusion npog nce lub kaum sab xis mus rau 156.6 degree, piv rau 140.2℃rau pob tshab npog tag nrho, thaum txo qhov glare rau UGR tsawg dua lossis sib npaug rau 19. Uniform LED qhov sib nrug (4-5mm) kuj ua kom lub teeb pom kev zoo thoob plaws lub raj ntev, tsis txhob cuam tshuam "zebra stripe" Rau SMD los yog pawg-pob LEDs, integrated optical lo ntsiab muag ntxiv redirect lub teeb los txhim kho uniformity.

Xyuas kom lub Fixture Compatibility

Txhawm rau kom yooj yim retrofitting,T8 LED tube teebyog tsim los kom phim qhov ntev ntawm tus qauv T8 fluorescent raj (1200mm ntev, 25.4mm txoj kab uas hla) thiab siv G13 tus pin configurations. Adjustable teeb tuav (nrog pins ntawm 0 degree, 45 degree, thiab 90 degree) hloov mus rau qhov sib txawv fixture orientations, kom lub teeb lub siab tshaj plaws siv raws li qhov yuav tsum tau daim ntawv thov-tseem ceeb rau qab nthab-mounted, phab ntsa{10}}mounted, los yog lwm yam installation scenarios.
