Raws li TrendForce' s LED thoob ntiaj teb cov khoom siv saw cov ntaub ntawv qhia, hauv lub hlis thib ob ntawm xyoo 2021, tus nqi ntawm cov khoom lag luam LED rau teeb pom kev zoo yuav nce los ntawm 0.3 ~ 2.3%, feem ntau vim tias LED teeb pom kev lag luam xav tau rov zoo. los ntawm thawj peb lub hlis mus rau lub hlis thib ob. Lub caij high-end tseem raug tswj hwm. Ib qho ntxiv, cov txheej txheem tsis txaus ntawm cov nqes dej LED ua los ntawm kev sib kis tseem tsis tau daws tau. Cov chaw tsim khoom lag luam teeb pom kev zoo tau nce lawv cov khoom siv dag zog kom tsis txhob poob rau xyoo dhau los qhov teeb meem tsis txaus. Nws tau kwv yees tias kev nce zuj zus ntawm cov khoom lag luam yuav tsav tag nrho lub xyoo Cov txiaj ntsig tsim tawm ntawm LEDs rau teeb pom kev zoo tau nce mus txog US $ 6.709 nphom, nrog rau kev loj hlob txhua xyoo ntawm 3.43%.
TrendForce qhia ntxiv tias tau txais txiaj ntsig los ntawm kev loj hlob sai hauv kev thov rau tib neeg ua rau pom kev zoo, teeb pom kev zoo, cog teeb pom kev zoo thiab teeb pom kev tshwj xeeb (xws li nuclear fais fab nroj tsuag teeb pom kev zoo, kws tshuaj, ua hlau ua lag luam teeb pom kev zoo), teeb pom kev zoo-theem LED ntim cov tuam txhab suav nrog Samsung LED (Samsung LED). LED), ams Semiconductor thiab Osram (ams / OSRAM), CREE LED, Lumileds, Seoul Semiconductor (Seoul Semiconductor), MLS, Tiandian (Xob Laim), thiab lwm yam, tau loj hlob zoo txij li thawj peb lub hlis twg. Kev loj hlob sai yuav tsum txuas ntxiv mus rau lub hlis thib ob.
Cov nthwv dej ntawm cov khoom ntim LED tau nce ntau pawg, suav nrog cov khoom nruab nrab sab hauv tsev thiab lub zog hluav taws xob qis LED cov khoom lag luam (qis dua 1 watt, tsis suav nrog 1 watt) rau kev siv hauv tsev thiab lag luam, xws li 2835 LED, 3030 LED thiab 5630 LED, nrog kev nce peb lub hlis twg. ntawm 0.3 ~ 2.3%, ntxiv rau sab nraum zoov lub teeb pom kev zoo LED cov khoom lag luam (siab dua 1 watt) rau sab nraum zoov thiab kev lag luam siv, xws li cov khoom siv hluav taws xob ceramic thiab 7070 LEDs, nce peb lub hlis twg yog 1.3 ~ 1.8%.
LED teeb pom kev lag luam xav tau muaj zog, cov tuam ntxhab maj nrawm txhawb cov khoom lag luam tshiab tom qab muaj kev sib kis los sib sau ua ke lawv tus kheej kev lag luam
Saib ntawm qhov nthwv dej ntawm tus nqi nce ntxiv los ntawm kev pom ntawm cov khoom lag luam, vim muaj kev cuam tshuam los ntawm kev sib kis xyoo tas los uas ua rau cov chips thiab cuam tshuam nrog cov khoom siv hlau nyoos kom nce, qee lub teeb pom kev zoo LED cov tuam txhab tab tom ntsib lub siab ntawm tus nqi nce nqi, thiab lawv tau nce lawv cov kev muag khoom yav dhau los ntawm cov nqi qis teeb pom kev zoo LED cov khoom. Txhawm rau tswj hwm cov hauv paus nyiaj tau los.
Ntawm tag nrho, txawm hais tias muaj kev nyuaj siab ntawm tus nqi nce ntawm cov khoom siv raw, teeb pom kev zoo LED cov tuam txhab tseem tab tom txhim kho cov khoom lag luam, suav nrog kev ua kom pom kev zoo thiab xim xim, thiab ua tiav tso tawm cov khoom lag luam uas ua tau raws li qhov xav tau tshiab ntawm kev ua lag luam tom qab sib kis los sib sau ua ke. lawv tus kheej kev lag luam. Thiab kev sib tw, xws li OSRAM thiab Lumileds tau pib teeb pom kev zoo LED cov khoom tsim los ntawm cov chaw tsim vaj tsev, thiab CREE LED cov khoom tsim nyog rau kev cog ntoo sab hauv thiab cog ntoo.
