LED Back Lit Vaj Huam Sib Luag

coj rov qab teeb vaj huam sib luag

Dab tsi yog qhov txawv ntawm ntug-lit thiab nraub qaum-lit LED vaj huam sib luag?

Ib ntug -lit LED vaj huam sib luag yog 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 kab rov tav rau hauv lub teeb - phau ntawv 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.

Lub nraub qaum -lit LED vaj huam sib luag yog ua los ntawm ib qho array ntawm LEDs haum rau ntawm kab rov tav phaj ci ntsa iab vertically los ntawm diffuser rau hauv qhov chaw kom pom kev. Rov qab-lit panels qee zaum kuj hu ua ncaj qha -lit panels.

Puas yog ntug-lit lossis rov qab-lit LED vaj huam sib luag zoo tshaj?

Ob qho qauv tsim muaj qhov zoo thiab qhov tsis zoo. Ntug-lit vaj huam sib luag yog thawj pawg- tsim cov vaj huam sib luag.

Ntug-lit tsim tau siv thawj qhov chaw rau ntau yam:

· Lub Teeb Qhia Vaj Huam Sib Luag (LGP) yog ib txoj hauv kev zoo thiab yooj yim rau diffuse lub teeb sib npaug, tsis txhob muaj kev pheej hmoo ntawm qhov kaj. Qhov zoo tshaj plaws LGP yog ua los ntawm acrylic (PMMA), uas muaj lub teeb kis tau zoo heev thiab yuav tsis daj dhau sijhawm.

Lub xub ntiag ntawm LGP txhais tau hais tias lub diffuser tsis yog tsuas yog lub luag haujlwm rau kev nthuav tawm lub teeb sib npaug, yog li cov khoom siv qis tuaj yeem siv rau hauv diffuser muab lawv tsis daj lub sijhawm.

· Tsis xav tau lub lens, ntug -lit tsim yog haum rau ntau yam sib txawv LED beam kaum.

· Lub tshav kub ntawm LED nti yog dissipated los ntawm tus ncej, yog li lub rear yog lub teeb thiab tsis kub, yog li tus neeg tsav tsheb yuav muab tso rau ntawm no yog xav tau.

Txhawm rau txo tus nqi ntawm ntug-lit panels, qee lub tuam txhab tau qhia cov khoom pheej yig dua thiab cov txheej txheem sib dhos uas cuam tshuam rau lawv qhov zoo. Qhov no feem ntau cuam tshuam txog LGPs. Qee cov tuam txhab tam sim no siv polystyrene (PS) lub teeb qhia, tab sis tsis muaj qhov sib ntxiv ntawm UV stabilizers, cov no yuav daj thaum lub sij hawm, tawm hauv nruab nrab ntawm lub vaj huam sib luag tsaus ntuj thaum lub periphery tseem ci. Tsis tas li ntawd, PS muaj qhov sib kis tsawg dua li PMMA.

Kev siv thev naus laus zis tau tso cai rau kev qhia txog backlit LED panels.

· LEDs tau ua haujlwm zoo dua, yog li qhov txiaj ntsig thermal muaj nyob hauv ntug -lit tsim tam sim no raug txo, tab sis tsis raug tshem tawm.

· Cov lo ntsiab muag tau txais pheej yig dua los tsim thiab niaj hnub cov nplaum txhais tau tias lawv tuaj yeem ruaj ntseg txuas rau txhua lub LED kom tsim tau ib qho teeb ci txawm tias tsis muaj kev pheej hmoo ntawm kev poob tawm - qee qhov ua ntej thiab pheej yig dua backlights Vaj Huam Sib Luag tsis ua hauj lwm.

· Microprismatic diffusers tau dhau los ua ntau dua, pheej yig dua thiab siv tau zoo dua, yog li kev ua haujlwm ob ntawm LGP / diffuser ua ke tsis tas yuav tsum tau ua.

· Vim hais tias pheej yig dua ntug-lit panels siv tsawg- transmittance LGP, tshem tawm LGP tag nrho, zoo li backlit panels, txhais tau tias backlit panels paub tias yuav ua tau zoo dua.
