Lens VS Reflector Uas yog qhov zoo tshaj plaws ntawm ob sab xis ntxiv rau LED illumination?

lens

Lub lens lem tau muab faib ua ib lub lens thiab ib lub lens secondary. Qhov "lens" peb feem ntau yog xa mus rau ib lub lens secondary, uas yog, ib qho teeb ci xws li teeb qhov muag teeb lossis lub COB, thiab nws zoo sib xws nrog nws. Txuj ci lo ntsiab muag yuav siv tau los ua kom tau qhov kev xav ntawm qhov muag, qhov yuav tsum tau ua.

Cov khoom tseem ceeb ntawm LED lens ntawm kev ua lag luam hnub no yog PMMA, uas muaj cov yas zoo thiab lub teeb siab hloov siab (nce txog 93%). Qhov tsis zoo yog tias qhov ntsuas kub tsis txaus, tsuas yog txog 90 degrees. Lub ntsiab thib ob lub lens ntawm kev ua lag luam yog feem ntau tag nrho cov qauv tsim tawm (TIR). Qhov tsim ntawm lub lens yog pob tshab nyob rau hauv pem hauv ntej ntawm lub lens, thiab tapered saum npoo yuav sau thiab qhia txog sab lub teeb. Lub overlapping ntawm lub teeb muaj peev xwm ua kom tau zoo meej lub teeb siv thiab zoo nkauj nqaij nyhuv. Lub lens TIR muaj kev ua haujlwm tshaj li ntawm 90% thiab tsuas yog siv lub me me-lub teeb (nqaj kaum <60 °),="" xws="" li="" cov="" teeb="" rooj="" laub="" thiab="" cov="" qab="">

Reflective khob

Feem ntau, lub teeb ci teeb ci muaj lub teeb rau ntawm 120 °. Yuav kom ua tau raws li qhov kev xav ntawm qhov muag, lub teeb ntim qee zaum siv tus zais kom tswj tau qhov kev nruam ntej, thaj chaw teeb, thiab qhov nqaij nyhuv.

Reflective khob khoom

Hlau reflector: Nws yuav tsum tau stamped thiab polished, thiab muaj lub cim xeeb ntawm deformation. Qhov zoo dua yog tus nqi qis, kev kub ntawm lub cev, thiab feem ntau siv rau cov uas yuav tsum tau ua kom tsis txhob muaj teeb pom kev zoo.

Yas Reflector: Ib zaug demoulding, siab kho qhov muag zoo siab, pom kev nco, me ntsis nqi, feem ntau siv hauv high-temperature teeb pom kev zoo rau cov ntsuas kub tsis tshua muaj. Thiab rau cov tuam txhab txawv teb chaws, cov yas yas yog yooj yim dua kom dhau txoj cai kev nyab xeeb, txhuas lub khob cij tsis yooj yim kom dhau txoj cai kev nyab xeeb

Feem ntau yog thaum TV series yog tshaj tawm hauv xov tooj cua, cov suab paj nruag rings, thiab qhov teeb meem qhov kawg ntawm cov neeg zoo thiab cov neeg phem tuaj dua: Cov lens thiab reflector puas zoo dua?

Qhov no yog qhov yuam kev uas tau ua yuam kev. Ua ntej, koj yuav tsum xub to taub cov cai. Dab tsi ua ntej koj muaj thiab lub teeb meem zoo li cas koj xav tau? Yog tias koj poob qis, nws yog qhov ua kom tau raws li qhov no. Yam twg yog qhov siv? Ib qho kev hais haum zoo, qee zaum ob zaug, yog ntau tshaj li kev ua si ib zaug.

Zoo optics zoo li ntev tau thaum lawv ua tiav qhov kev xav tau qhov muag nyhav. Haum yog qhov zoo tshaj plaws secondary optics!
