Kev txhim kho ntawm LED teeb pom kev zoo yuav txo tus nqi ntawm LED
Tam sim no, Cree, lub tuam txhab Asmeskas loj tshaj plaws, yog qhov txaus siab tshaj plaws. Lub luminous efficiency ntawm dawb LEDs tau mus txog 186 lumens ib watt. Hauv cov khoom lag luam ntu, cov neeg siv khoom tau pib muab cov neeg siv khoom nrog tag nrho luminous flux ntawm 239 lumens thiab luminous efficiency ib watt. 162 lumens khoom. Raws li rau Nichia, Nichia tshaj tawm tias nws tau ua tiav tsim lub zog qis-dawb dawb LED nti nrog lub siab tshaj plaws luminous flux hauv kev lag luam. Cov LED dawb tso tawm los ntawm Nichia muaj qhov ua tau zoo ntawm 249 lumens ib watt ntawm qhov tam sim no ntawm 20 mA. Nichia yeej ib txwm tuav lub ntiaj teb no txoj hauj lwm nyob rau hauv kev loj hlob ntawm tsawg-power LEDs, nrog ib tug luminous efficiency ntawm 150 lumens ib watt thiab 169 lumens ib watt, uas tam sim no tau mus txog 249 lumens ib watt. Piv nrog rau lwm cov khoom siv hluav taws xob siv hluav taws xob uas tau ua tiav, LED luminous efficiency tseem muaj chaw rau kev txhim kho. Raws li kev soj ntsuam ntawm kev tsim kho thev naus laus zis ntawm ntau lub tuam txhab nyob rau theem no, kev ua haujlwm luminous ntawm LED monomers muaj lub sijhawm nce mus rau 188 lumens ib watt, qhov sov so lub teeb tseem muaj lub sijhawm ua tiav ntawm 138 lumens ib watt. Yog hais tias tag nrho cov teeb pom kev zoo ntawm lub luminaire ntxiv, lub caij nyoog ntawm LED ua teeb pom kev zoo tau zoo dua los ntawm qhov ntawd.
LED cov nqi yuav poob sai heev. Tsis tas li ntawd, los ntawm qhov kev xav ntawm cov nqi teeb pom kev zoo, piv nrog cov teeb fluorescent, lub teeb txuag hluav taws xob, lub teeb incandescent thiab cov roj siv hluav taws xob siab (HID), chav tsev nqi ntawm cov teeb pom kev zoo ib txwm tsis muaj chaw txo qis piv nrog LED teeb. Tus nqi ntawm LED teeb qhov chaw xws li 4,100 txog 6,500K yog kwv yees kom txo qis los ntawm ntau dua 90%. Kev ua lag luam hauv Teb Chaws Asmeskas ua piv txwv, raws li kev paub txog kev lag luam, LED teeb pom kev zoo yuav muab piv rau cov teeb pom kev ib txwm muaj nyob rau hauv cov nqe lus ntawm tus nqi. Yog hais tias lub luminous efficiency ntawm LEDs yog raws li kev kwv yees los ntawm US Energy Administration, yuav muaj feem ntawm kev txiav mus rau hauv txawv teeb pom kev zoo qhov chaw yog khi kom nce. Raws li kev nkag mus rau lub teeb pom kev tsis ncaj lossis qhov kawg lub teeb pom kev lag luam, ntxiv rau qhov yuav tsum tau txhim kho thev naus laus zis ntawm LED nws tus kheej, tus nqi poob qis, kev txhim kho cov teeb pom kev zoo thiab qhov zoo ntawm cov teeb pom kev zoo yog txhua yam teeb meem uas LED teeb pom kev zoo yuav tsum tau ntsib. yav tom ntej. Txij li thaum txoj kev loj hlob ntawm LED teeb pom kev zoo, qee cov tuam ntxhab tau qhia LEDs nrog lub teeb pom kev zoo ntawm ntau dua 160 lumens ib watt. Yog hais tias qhov nruab nrab luminaire efficiency yog kwv yees li 50 ~ 70%, tag nrho cov efficiency ntawm LED teeb fixtures yog tsawg kawg yog 180 lumens ib watt. Rau cov teeb pom kev zoo, lossis hloov cov teeb ci uas txwv tsis pub, lawv twb tsim nyog nkag mus rau hauv kev ua lag luam. Raws li kev soj ntsuam ntawm Optoelectronics Association (PIDA), LEDs yuav ua lub luag haujlwm ntawm lub teeb pom kev hauv zos lossis teeb pom kev tseem ceeb ntawm theem no. Lub sijhawm ntawm qhov chaw teeb pom kev zoo.
