A backlit LED vaj huam sib luagyog ua los ntawm ib tug array ntawm LEDs haum rau ib tug kab rov tav phaj ci ntsa iab vertically down los ntawm ib tug diffuser rau hauv qhov chaw kom illuminated.Back-lit panels qee zaum kuj hu ua direct-lit panels.

An edge-lit LED vaj huam sib luagyog ua los ntawm ib kab ntawm LEDs txuas rau lub thav duab (los yog ib ncig) ntawm lub vaj huam sib luag, ci ntsa iab horizontally mus rau hauv lub teeb qhia phaj (LGP).Lub LGP coj lub teeb mus rau hauv qab, los ntawm lub diffuser rau hauv qhov chaw hauv qab no.Ntug-lit panels qee zaum kuj hu ua sab-lit panels.

Yog ntug-lit lossis rov qab-litLED vaj huam sib luagzoo tshaj?

Ob qho qauv tsim muaj qhov zoo thiab qhov tsis zoo.Ntug-lit vaj huam sib luag yog thawj zaug uas tau tsim tawm ntau.

Lub ntug-lit tsim tau xaiv rau ntau yam:

• Lub teeb-kev taw qhia phaj (LGP) yog ib txoj hauv kev zoo thiab yooj yim rau diffuse lub teeb, zam kev pheej hmoo ntawm qhov kaj.
• Lub xub ntiag ntawm LGP txhais tau hais tias lub diffuser tsis yog lub luag haujlwm rau kev nthuav tawm lub teeb sib npaug kom cov khoom siv qis siv tau, yog tias lawv tsis daj nrog hnub nyoog.
• Tsis tas yuav tsum tau lo ntsiab muag thiab lub ntug teeb tsim ua haujlwm zoo nrog ntau yam sib txawv ntawm cov kab teeb ci LED.
• Thaum tshav kub kub los ntawm LED chips yog dissipated ntawm lub thav duab, yog li lub rear yuav ua tau lub teeb-yuag thiab nws yuav tsis kub, yog li ntawd tus neeg tsav tsheb yuav tsum tau muab tso rau ntawm no yog tias xav tau.

Thaum lub sij hawm lub drawbacks ntawm txoj kev no ua rau lawv tus kheej pom.Cov khoom siv zoo tshaj plaws rau LGP yog acrylic (PMMA), tab sis qhov no tuaj yeem kim heev, yog li pheej yig dua polystyrene (PS) feem ntau siv.Yog tias nws tsis sib xyaw nrog UV stabilizing additives, PS LGPs tig daj thaum lub sijhawm ua haujlwm tau poob, lub teeb tso zis tig daj daj thiab qhov nruab nrab ntawm lub vaj huam sib luag darkens thaum lub periphery tseem ci.

Tsis tas li ntawd, qee qhov rear reflectors (saib daim duab saum toj no) tev tawm nrog lub hnub nyoog ntxiv degrading qhov kev ua tau zoo ntawm ntug-lit LED panels.

Kev nce qib tam sim no tau tso cai rau lub cim tshiab ntawm back-lit LED panels tau qhia.Cov no feem ntau ua haujlwm tau zoo nrog cov nqi tsev qis dua li yav dhau los LED panels.

• LEDs tau ua haujlwm tau zoo dua, yog li qhov txiaj ntsig thermal muaj nyob rau hauv qhov tsim teeb pom kev zoo ua qhov tsis tseem ceeb.Back-lit designs tsis kub heev uas tus tsav tsheb tsis tuaj yeem muab tso rau tom qab.
• Cov lo ntsiab muag tau pheej yig dua los tsim thiab niaj hnub cov nplaum txhais tau hais tias lawv tuaj yeem ruaj ntseg ruaj khov rau txhua lub LED los tsim kom muaj lub teeb ci txawm tias tsis muaj kev pheej hmoo tias lawv yuav poob - qhov ua tsis tiav nrog qee qhov ua ntej thiab pheej yig dua rov qab teeb.
• Micro-prismatic diffusers tau dhau los ua ntau dua, tsis tshua kim thiab siv tau zoo dua, yog li ob qhov kev txiav txim ntawm LGP / diffuser ua ke tsis tas yuav tsum tau ua.
• Kev tshem tawm ntawm LGP hauv cov qauv teeb pom kev rov qab txhais tau hais tias lub peev xwm txuag hluav taws xob ntau dua nrog cov qauv teeb pom kev zoo, yog tias tag nrho lwm yam sib npaug.

Lub lag luam teeb pom kev zoo tam sim no lees txais cov vaj huam sib luag rov qab kom yooj yim raws li ntug teeb vaj huam sib luag thiab, vim tias cov vaj huam sib luag rov qab yuav tsum tsis muaj LGP lossis lub nraub qaum, lawv feem ntau yog tus nqi qis tshaj nrog rau cov khoom siv hluav taws xob zoo tshaj plaws.

Dab tsi yog teeb meem nrog pheej yigbacklit LED panels?

Qhov no yog qhov yuav tsum tau saib rau.

• Muaj tsawg LEDs tau siv.Tsawg LEDs ntau dhau (feem ntau 36 lossis tsawg dua) txhais tau tias lawv yuav tsum tau tsav ntawm lub siab tam sim no los tsim lub teeb pom kev xav tau.Piv nrog rau cov qauv tsim siv ntau LEDs, qhov no tsis tshua muaj txiaj ntsig (LEDs ua tau zoo tshaj plaws nrog cov tsav qis), ua kom muaj cua sov ntau dua, ua kom lub neej luv ntawm LEDs thiab maj mam txo qis lumen.
• Lub cev yas.Qhov zoo dua back-lit panels siv lub cev hlau.Qhov no yog qhov ua tau zoo dua li lub dab dej kub dua li lub cev (khoom pheej yig dua) yas.LEDs tsim ib co cua sov thiab qhov no yuav tsum tau dissipated yog tias lawv lub neej tsis yog yuav luv luv ntxiv.
• Lub teeb faib tsis sib tshooj.Nyob rau hauv ib tug zoo back-lit vaj huam sib luag txhua LED yog ib tug neeg lo ntsiab muag thiab lo ntsiab muag yog tsim los kom lub teeb ntawm txhua LED overlaps lub teeb los ntawm nws cov neeg nyob ze.Qhov no yuav ua rau muaj kev cuam tshuam txawm tias muaj teeb meem thiab qee qhov kev ua haujlwm tau zoo nyob rau hauv qhov xwm txheej uas ib leeg LED tsis ua haujlwm.Kev tsim lub lens tsis zoo thiab muaj pes tsawg tus LEDs yuav txo tau qhov sib tshooj ntawm LEDs thiab ua rau muaj kev pheej hmoo ntawm qhov kaj thiab tsaus me ntsis rau pem hauv ntej ntawm qhov haum.
• Cov lo ntsiab muag puas ruaj khov rau hauv txoj hauj lwm?Tsuas yog lub sijhawm yuav qhia, tab sis qhov kev pheej hmoo yog tias cov cua sov tsim los ntawm LEDs, ua ke nrog cov nplaum nplaum pheej yig tsis zoo, yuav ua rau cov lo ntsiab muag poob.Qhov tshwm sim yuav yog qhov tsis sib xws ntawm lub teeb faib thiab tejzaum nws glare ib yam nkaus.
• Built-in tsav tsheb.Cov neeg tsim khoom tuaj yeem txuag nyiaj los ntawm kev tsim tus tsav tsheb rau hauv lub cev, tab sis qhov no muaj ntau yam tsis zoo.Nws tsis tuaj yeem hloov tau thaum muaj teeb meem thiab yuav tsis muaj qhov dimming lossis kev xaiv xwm txheej ceev.Nws yog ib txoj hauv kev yooj yim heev.
• Tshawb xyuas cov ces kaum ntawm tus ncej.Nyob rau ntawm pheej yig dua panels ib tug unsightly sib koom yuav tshwm sim.
