High teeb efficiency, siab zog hloov dua siab tshiab efficiency nyob rau hauv uas tsis muaj luminosity (efficiency) ntawm hluav taws xob mus rau hauv lub teeb zog - uas yog lub xeev hluav taws xob, heev haum rau cov uas tsis luminosity (xws li xov tooj txawb backlight, hmo ntuj lub teeb) siv nyob rau hauv coob. Tab sis thaum lawv luminosity nyiam Taiwan lub taub hau teeb, los yog ntau dua, LED efficiency siab tshaj tungsten filament qhov muag , tab sis zoo dua fluorescent teeb (kuj hu ua lub teeb raj los yog hlab) pluag: IEEE (lub koom haum hluav taws xob thiab electronics engineers) qhov teeb meem ntawm IEEE Spectrum tau paub meej tias qhov no.

Ceev cov lus teb: cov tshuaj tiv thaiv (mus) lub sij hawm yog luv luv - peev xwm ua tau siab heev flicker zaus, thiab txawm ua rau "pom lub teeb network" tau. Ntev lub neej: ntev lub neej - tsis muaj kev cuam tshuam nws lub neej los ntawm tas mus li flash, nyob rau hauv lub kom tshav kub dissipation thiab ib puag ncig ntawm mus txog 35000 ~ 50000 teev (incandescent qhov muag teeb, fluorescent teeb yog 10000 ~ 15000 teev, rau 1000 ~ 2000 teev). Av qeeg resistant: poob siab resistant thiab lwm yam cov neeg kho tshuab poob siab - vim hais tias nws yog ib tug khoom tivthaiv, tsis muaj filament, iav npog, thiab lwm yam, tus txheeb ze fluorescent teeb, incandescent teeb mas ntau mob taub hau. Me volume - nws tus kheej ntim tau ua heev me me (tsawg tshaj li 2 hli). Ib qho yooj yim mus siab rau - nrog lub teeb me me luaj li cas thiab yooj yim mus cuag tus yuav tsum tau degree ntawm faib los ntawm lens, los ntawm hloov nws encapsulation zoo, nws lub teeb lub los loj lub scattering rau zoo taw tes ntawm ua kom pom tseeb yuav tsum mus txog. Monochromatic siv - vim hais tias nws yog ib tug theem ntawm lub teeb tawm txim liab los ntawm photons, lub wavelength yog tus ib (tus txheeb ze rau feem ntau dag qhov chaw), thiab yuav muab tau ib tug ntau yam ntawm tej yam yooj yim xim tsis muaj ib tug lim. Xim: cov xim teb yog ib tug broad - ib feem dawb LED xim teb yog dav dua lwm lub teeb dawb qhov chaw.

disadvantages

High nqi: cov laus LED teeb yog tsawg npaum thiab tseem kov hwj huam ntau dua cov fluorescent teeb nyob rau hauv kev teeb pom kev zoo. Ib txhia LEDs txawm haus tsawg hluav taws xob dua lub teeb qhov muag teev. Ib txhia tsim kev siv ntau hom LEDs, thaum tswj tag nrho cov luminosity nyob rau hauv txhua LED yuav ua hauj lwm nyob rau hauv uas tsis muaj luminosity, li no ua efficiency, tab sis, yog li heev kom tus nqi nqi yog siab tshaj lwm yam qhov muag teev.
