C Philips LED Lamp Beads OB Ntim Puas Tau Txais Kev Lag Luam?

2023-01-25

Vim li cas COB ntim khoom nyiam los ntawm kev ua lag luam? COB (CHIP-BOARD) pob ntawm LED teeb hlaws tau txais kev lag luam ntau ntawm kev lag luam tam sim no. Tsis tas li ntawd, qhov ua tau zoo thiab tus nqi ntawm kev tsim khoom thiab kev tsim khoom yog kev zam. Hauv kev ua lag luam, cov khoom seem yog huab tais, thiab nws yog lub hauv paus ntsiab lus ntawm kev khwv nyiaj. Cia peb piav qhia lub siab ntawm COBLED los ntawm kev ua haujlwm ntawm kev tsim khoom thiab kev tsim khoom thiab cov nqi. Kev ua tau zoo ntawm COB ntim ntawm cov txheej txheem tsim khoom yog qhov tseem ceeb ntawm kev ua kom adhesion, decentralization, spanning, thiab ntim. Piv nrog rau cov khoom lag luam SMD ib txwm muaj, cov khoom qub ntim khoom tsim thiab cov qauv tsim khoom suav nrog 10% ntawm tus nqi ntawm cov khoom siv, thiab tom kawg tsis suav txog 15%. Hais txog tus nqi, noj 1.2M hnub ci teeb ua piv txwv, siv COBLED lub teeb ci, tus nqi ntawm 1600LM lub teeb tag nrho tuaj yeem raug txo los ntawm 25%, 1800LM tuaj yeem txo los ntawm 29%, thiab 2000LM tuaj yeem txo los ntawm 33%. . Qhov no yog qhov zoo heev rau LED teeb pom kev zoo kom kis tau sai li sai tau. Nws tsis tuaj yeem ua nws ib leeg. COBLED lub teeb qhov chaw tshaj li cov tsoos SMD ntim LED, nyob rau hauv cov nqe lus ntawm thermal kuj thiab lub teeb zoo. SMD ntim tshuab thermal kuj yog: chipsolid siv lead ua kua nplaum sib koom ua ke pastecopper foilinsulation txheej txheej txheej, thiab COB ntim system thermal kuj yog: chipsolid siv lead ua kua nplaum, yog li nws tuaj yeem paub tias COB qhov kub ntawm lub ntim system yog qis dua SMD ntim, uas tau nce kev pab cuam lub neej ntawm LED. Vim tias SMD ntim yog li ntawd, qhov xwm txheej ntawm thaj chaw txuas nrog ntau yam khoom siv sib cais ntawm PCB pawg thawj coj los tsim cov teeb pom kev zoo ntawm LED. Txoj kev zoo li no tsis tiv thaiv qhov teeb meem ntawm lub teeb, glare thiab shadowing. COBLED yog qhov chaw ntim khoom sib xyaw. Txoj kev xav thiab kev sib haum xeeb yooj yim tau raug txo. Qhov poob ntawm lub teeb refraction yog txo. Nws zoo dua nrog lub teeb zoo. Tsis muaj teeb meem los ntawm kev xav ntawm tus nqi thiab kev siv, COB ntim yog txoj hauv kev muaj txiaj ntsig los daws cov teeb meem kub kub thiab cov nqi siab kawg hauv SMD ntim cov txheej txheem uas twb muaj lawm. Tus naj npawb ntawm COB ntim LEDs ntawm lub khw tau maj mam nce me ntsis.
