LED qhov muag teev yog hnyav thiab lawv cov iav tsis yooj yim, yog li lawv feem ntau siv lub plhaub yas los tiv thaiv kev tawg. Lub plhaub plhaub yas yuav tsum muaj lub teeb xa hluav taws xob siab, siab diffusion, tsis muaj glare, thiab tsis muaj duab ntxoov ntxoo, nrog lub teeb xa hluav taws xob ntau dua 90%, thiab cov nplaim hluav taws kub thiab kev cuam tshuam.
Lub hauv paus ntsiab lus kho qhov muag ntawm LED teeb pom kev yog tias lub teeb dhau los ntawm cov txheej txheem diffusion ua los ntawm PC / PMMA / PS lossis cov substrates zoo sib xws ntsib qhov nruab nrab (diffusing particles) nrog qhov sib txawv refractive index, uas ua rau ntau-lub kaum sab xis, ntau- kev taw qhia refraction, reflection, thiab tawg, yog li ua tiav lub teeb diffuse. Cov ntaub ntawv tau hloov zuj zus los ntawm iav thiab pob tshab cob rau cov ntaub ntawv tshiab uas hais txog qhov sib npaug ntawm lub teeb xa mus thiab kev ua haujlwm tawg.
LED teeb plhaub tuaj yeem muab faib ua cov khoom siv, suav nrog PC, PMMA, PS, iav, thiab yas. Plastic teeb plhaub muaj kev tiv thaiv kev poob qis, tsim qauv mis nyuj dawb rau txo qis, thiab lub teeb xa hluav taws xob siab. Lampshades ua los ntawm cov ntaub ntawv zoo li PC ua tiav lub teeb diffusion los ntawm ib txheej diffusion, muab lub teeb pom kev zoo ib yam. Tsis tas li ntawd, muaj cov qauv tsim patented rau LED teeb vaj tsev nyob uas ua kom muaj cua sov dissipation, nrog rau cov ntse LED optical teeb npog, kom ua tau raws li qhov yuav tsum tau muaj xws li lub teeb xa hluav taws xob siab thiab siab diffusion.
