Cov kab hluav taws xob sib txuas ua ke yog tsim los ntawm 15 x 15mm square acrylic rod. Nco tseg tias qee cov yas yas muaj qhov nqus tau ntau dhau ntawm qhov pom ntawm 420nm thiab qis dua; txhawm rau txheeb xyuas qhov no ua ntej koj pib, ci UV LED los ntawm tus pas nrig thiab txheeb xyuas tias nws tsis ua rau lub nqaj qis dhau (siv ib daim ntawv dawb yog li koj tuaj yeem pom qhov ci ci xiav los ntawm cov xim dawb hauv daim ntawv).

Koj tuaj yeem luam tawm 3D luam tawm jig rau txhuam cov pas nrig lossis tsim koj tus kheej los ntawm qee cov ntawv yas uas tsim nyog. Txiav tus pas nrig kom kwv yees li 73 hli thiab xuab zeb thiab txhuam ob qho kawg. Tom qab ntawd kho lub jig rau ob sab sib txawv ntawm tus pas nrig siv ob daim nplaum nplaum. Xuab zeb siv 40 daim ntawv ua kom txog thaum koj nyob hauv 0.5mm lossis ntau dua ntawm cov kab jig, tom qab ntawd nce zuj zus mus rau 80, 160, 400, 800, 1500, 3000, 3000, 5000 thiab thaum kawg 7000 cov ntawv kom tau txais cov kab xev ci. Tom qab ntawd tshem tawm cov jig thiab rov ua haujlwm rau xuab zeb ntawm ob sab. Tam sim no koj yuav tsum muaj daim kab xev dav uas haum rau kev teeb tsa hauv cov phaj sib txuas ua ke. Qhov nqaim kawg yog 6mm x 6mm kom haum rau cov dav hlau nqa mus.

Nco tseg: hauv kuv qhov xwm txheej kuv tsis tau xuab zeb mus rau 6mm x 6mm yog li cov khoom sib txuas tau rub tawm me ntsis los ntawm cov phaj mounting. Qhov no tsis muaj teeb meem li 6mm fiber ntau yog qhov haum haum thiab yuav tsoo nrog qhov nqaim kawg ntawm cov khoom sib txuas yog thawb mus deb txaus.

Saj rov qab txog 1 nti ntawm lub tsho sab nrauv los ntawm 6mm fiber, saib xyuas kom tsis txhob puas cov fiber nws tus kheej. Tom qab ntawd, yog tias lub tsho sab nrauv ntawm cov fiber ntau tsis haum txaus rau hauv phaj txuas, tsuas yog qhwv ib daim kab xev puag ncig nws. Tom qab ntawd nws yuav tsum tuaj yeem raug thawb rau hauv thiab pw tsaug zog zoo nrog cov pyramid sib xyaw. Mount tag nrho lub rooj sib txoos mus rau lub hauv paus hauv kab nrog cov khoom siv fiber ntau.

Nco ntsoov tias koj poob qee lub teeb thaum ua ke. Koj tuaj yeem pom qhov laj thawj los ntawm cov kab ntawv kho qhov muag saum toj no, vim tias ua kom pom lub teeb qis kuj tseem ua rau lub kaum sab xis nce ntxiv thiab peb poob qee lub teeb hauv cov txheej txheem. Txog qhov siab tshaj plaws ntawm ib lub yoj ib ntus, siv cov phaj fiber ntau txuas txuas los xaiv tawm LED lossis LED ncaj qha mus rau 3mm fiber.

Qhov no tsuas yog luam tawm thib ob ntawm cov ntawv qhia fiber ntau. Ib zaug ntxiv, nco ntsoov luam tawm ntawm 105% nplai kom tso cai tshem tawm cov fibers los ntawm lub qhov. Koj yooj yim ntswj cov phaj no hauv kab nrog cov ntawv qhia fiber ntau, tshem cov ntsia hlau sib dhos ua ke thiab hloov nws nrog cov phaj no. Tsis txhob hnov qab ua kom haum nws txoj hauv kev puag ncig, lub qhov tsuas yog kab hauv ib txoj kev!.

Tam sim no muab cov 12 daim ntawm cov fiber uas koj txiav tawm rau hauv lub qhov hauv phaj. Txhawm rau tshem tawm ib lossis ntau lub wavelengths, tsuas yog tshem tawm ib daim ntawm cov fiber thiab tso ntev dua rau hauv lub qhov. Koj tuaj yeem tshem tawm tag nrho 12 nthwv dej ib ntus yog tias koj xav tau.

Kauj Ruam 15: Ntau Lub Hwj Chim! Ntau Wavelengths

Tus Pi tuaj yeem tsav ntau txoj hauv kev yog tias koj xav tau. Txawm li cas los muaj LEDs hauv lwm qhov nthwv dej yog qhov yuav yog qhov nyuaj. Koj tuaj yeem tau txais 365nm UV LEDs pheej yig tab sis cov yoog tau yooj yim fiber 6mm cable pib nqus tau zoo txawm tias ntawm 390nm. Txawm li cas los xij kuv tau pom tias cov tib neeg cov fibers yuav ua haujlwm nrog lub nthwv dej ntawd, yog li yog tias koj xav tau, koj tuaj yeem ntxiv lossis hloov lub LED kom muab lub sijhawm luv luv UV rau koj.

Lwm qhov muaj peev xwm yog ua kom pom kev ci ntsa iab los ntawm ob npaug ntawm LEDs. Piv txwv li, koj tuaj yeem tsim thiab luam tawm 5 X 5 fiber ntau txuas (lossis 4 X 6) thiab muaj 2 LEDs rau ib channel. Nco ntsoov tias koj xav tau lub zog loj dua li koj yuav tau kos ze li 20 amps. Txhua lub LED xav tau nws tus kheej ua rau tus neeg tawm tsam poob; tsis txhob muab cov LEDs ncaj qha. MOSFETs muaj ntau dua li lub peev xwm los tsav ob lossis ntau lub LEDs ib channel.

Koj tsis tuaj yeem siv lub zog LEDs siab dua vim tias lawv tsis tso lub teeb los ntawm thaj chaw me me zoo li 3W LEDs thiab yog li koj tsis tuaj yeem ua haujlwm tau zoo ob peb leeg. Saib 'kev txuag ntawm etendue' kom nkag siab tias vim li cas qhov no yog.

Lub teeb poob los ntawm cov khoom sib txuas yog siab heev. Qhov no hmoov tsis yog qhov tshwm sim ntawm cov cai ntawm physics. Hauv kev txo qis lub vojvoog peb kuj nce nws qhov sib txawv ntawm lub kaum ntse ntse thiab yog li qee lub teeb khiav tawm vim tias lub teeb qhia thiab fiber ntau tsuas muaj lub kaum sab xis lees paub nyob ib puag ncig 45 degrees. Nco ntsoov tias lub zog tso tawm los ntawm tus kheej cov khoom siv fiber ntau yog qhov muaj txiaj ntsig ntau dua li qhov sib txuas ua ke sib txuas ua ke.
