Cov lus qhia no qhia yuav ua li cas tsim thiab tsim kom muaj lub teeb ci ci LED rau koj lub thoob dej yug ntses. Dab tsi ua rau qhov kev qhia no txawv ntawm lwm qhov uas tau ploj mus ua ntej yog tias kuv tab tom siv HBLEDs siv cov LEDs ib txwm muaj.

Kuv pom HBLED tshiab los ntawm Optek uas yog tus nqi qis dua li ntau lub zog LEDs. Optek LED nyob ib puag ncig 50 xees hauv qhov ntau ntawm 100+. LED yog me me ntawm tsuas yog 3.5mm square. Tab sis, LED ncaws tawm 1/2 watt ntawm lub teeb. Muaj qee qhov tsis zoo rau cov LEDs no. Ua ntej tshaj, lawv yog cov nplaim taws. Qhov thib ob, lawv yuav tsum tau txuas nrog qee yam ntawm cov cua sov. Ob peb yam uas ua rau lub teeb nthuav tawm ntawm no txias heev. Ua ntej tshaj, lub teeb yog ua los ntawm kev zom cov LEDs nruab nrab ntawm ob qhov mob ntawm iav. Cov iav ua raws li cov cua sov zoo heev. Cov iav Sandwich kuj tau ntim ib ncig ntawm ntug kom nws cov dej nruj. Qhov thib ob, lub teeb yuav luag pom tseeb ua los ntawm iav. Ntxiv rau, txij li HBLEDs me me tiag, lawv tsis cuam tshuam lwm lub teeb thoob dej yug ntses. Qhov no ua rau yooj yim ntxiv lub teeb LED tshiab thiab txuas ntxiv siv cov thoob dej thoob dej yug ntses uas koj twb muaj lawm. Tus so ntawm cov lus qhia no tham txog kev tsim 14 watt HBLED teeb rau koj lub thoob dej yug ntses.

Optek LED, ua rau sab saum toj, yuav tsum tau teeb tsa rau qee yam ntawm lub rooj tsav xwm hauv Circuit Court. Kuv tsim cov pawg tswj hwm hauv qab no kom yooj yim siv tau. Tsis tas li, lub rooj tsav xwm xav tau los pab txhawb kev hloov pauv cua sov. Lub neej muaj txiaj ntsig tuaj yeem tsuas yog ntseeg tau yog tias LED tsis kub heev.

Lub nkoj thauj khoom yog tiaj tus nyob rau sab nraub qaum kom nws tuaj yeem ua kom sov sov rau lub dab dej kub. Lub Rooj Tswjhwm Saib kuj tseem tso cai rau cov xaim txuas rau ntawm ntug ntawm lub rooj tsavxwm. Thaum kawg, lub rooj tsavxwm muaj cov cua sov loj los pab tshem tawm cov cua sov thiab hloov nws mus rau lub rhaub dej kub. Ua tibzoo saib cov duab txuas rau kom paub meej ntxiv.

Yuav ua li cas txoj hauv kev zoo dua los hloov cua sov dua li siv daim iav iav. Cov iav phaj hloov cua sov zoo heev. Cov iav tseem pheej yig - phaj iav tsis kim dua Plexiglas. Kuv yooj yim siv qee daim duab thav duab iav uas kuv twb tau tso nyob ib puag ncig lub tsev. Kuv txiav ob daim phiaj 18 "x 3 1/2" nrog lub tswv yim ntawm kev sib khi cov LEDs ntawm ob daim phiaj. Qhov qhib qhov sib txawv nyob ib ncig ntawm ntug ntawm lub khob yog tom qab ntawd muab ntim nrog cov hlaws ntawm silicon sealant. Ib zaug kaw, iav zoo li khov heev - ob daim hlau ua ke ua ke ua rau lawv muaj zog dua.

Thaum sib dhos, LED cov laug cam yog super-glued txoj cai mus rau iav. Kuv siv 24 LEDs tag nrho. Ntawm 24 LEDs, 5 yog sov dawb thiab 19 yog xiav. Qhov no muab rau kuv 125 lumens ntawm sov sov thiab 114 lumens ntawm xiav.

Txhawm rau kom tau txais qhov ntau tshaj ntawm lub teeb los ntawm LEDs txhua qhov xav tau 150mA ntawm tam sim no. Tsis muaj tus tswj hwm qhov no nyuaj rau ua tiav. Raws li cov LEDs sov lawv qhov hluav taws xob qhov chaw hloov pauv. Yog li, kom ua kom 150mA ntws, qhov hluav taws xob yuav tsum tau hloov kho tas li. Lwm txoj hauv kev yog kom muaj kev tiv thaiv thiab ntxiv qhov loj tam sim no txwv kev tiv thaiv. Tam sim no txwv cov resistor tsis yog tsim qauv zoo nkauj heev.

Kuv tau xaus siv rau ntawm 6 LEDs hauv koob nrog LM317 tus tswj hwm. Tus tswj hwm tau xaim/teeb tsa los tswj hwm tam sim no hauv daim ntawv thov no. Ua tibzoo saib cov duab kos & duab kom paub meej ntxiv.

Kev tsim qauv tham ntawm no siv 24 volt / 600mA / 14 watt phab ntsa fais fab mov (10 bucks los ntawm Mouser). Ntawm cov 14 watts, 12 watts raug xa mus rau LEDs hauv thoob dej yug ntses. Qhov seem ob watts tau siv hauv cov tswj hwm tam sim no.

Siv tus pas ntsuas kub, Kuv ntsuas lub ntsuas kub ntawm LED kom siab tshaj ntawm 105 degrees F. Qhov ntsuas kub no tau siv sab nraum lub khob. Tam sim no lub chaw tswj hwm (kaw) qhov siab tshaj ntawm 110 degrees F thiab lub zog tso tawm ntawm 115. Yog li, tag nrho peb qhov kub tsuas yog sov rau qhov kov. Tsis muaj dab tsi tau kub tiag. Kuv vam tias qhov no yuav pab lwm tus uas yuav xav txog kev tsim cov ntawv thov nrog HBLEDs. Yog xav paub ntxiv, thov mus ntsib kuv lub vev xaib ntawm "ph-elec.com". Kuv tabtom ua tus nqa HBLED rau txhua tus neeg uas yuav txaus siab. Ua tsaug, Jim
