Qee qhov kev thaiv txoj hauv kev lees paub dav dav ntawm LED hauv tsev yog tus txheeb ze tus nqi siab ib lumen thiab cov teeb meem hloov pauv thiab tsis meej pem. Nyob rau lub hlis tsis ntev los no, ntau qhov kev txhim kho tshiab cog lus tias yuav coj peb mus ib kauj ruam ze rau lub ntiaj teb LED-powered. Ua nws qhov cue los ntawm ATX system uas ua rau peb lub khoos phis tawj, kab tshiab ntawm "Green-mode" adapters yuav hloov qhov hluav taws xob los ntawm 100v txog 240v, AC lossis DC, los ua ke sib txuas ntawm 1- lossis 3-watt LEDs hauv tus lej ntawm 1 txog 7. Cov qauv no nyob hauv qab 1 "hauv qhov ntev thiab tuaj yeem tso rau hauv lub hauv paus ntawm cov teeb pom kev zoo hauv tsev. txuas nws mus rau 8 x 100-milliAmp "Superflux" LEDs ua ke, uas tso cai rau kuv kom yooj yim ua kom sov-ua kom poob thiab lub teeb tawg.

Kauj ruam 1:

Tus qauv tuaj yeem tau txais ntawm no txog US $ 3.00 hauv ib qhov ntau, suav nrog kev xa khoom. Qhov 3-watt tsim txhais tau tias tsis muaj hluav taws xob ntau dua 5-volts ntawm ib qho ntawm LEDs, thiab lawv raug cais tawm ntawm lub hauv paus. Qhov loj " MHX "lub tshuab hluav taws xob pom hauv cov duab tau siv los lim cov tswv yim, yog li nws cov hlau ua rau nqa qhov hluav taws xob siab. Npog lawv nrog daim kab xev hluav taws xob kom nyab xeeb. Qhov "Green-mode" tsim kho thiab ua kom yooj yim tawm qhov hluav taws xob thiab siv nws los tsav tus oscillator ntawm kwv yees li 100KHz. Qhov xwm txheej-nthwv dej no tau siv rau lub tshuab hluav taws xob me me uas hloov nws mus rau qhov qis dua. Cov dej ntws tawm thiab tawm thiab ntsuas kub tau ntsuas 100000 zaug ib pliag thiab cov oscillator raug kaw kom txog thaum rov ua haujlwm tau zoo.

Kauj ruam 2: LEDs

Cov LEDs kuv siv ntawm no yog 100mA (thiaj li hu ua 0.5-watt) "Superflux" lossis "Piranha" LEDs. Koj tuaj yeem tau txais lawv ntawm no. Lawv tuaj yeem tuav lub zog no yam tsis muaj cua sov ntau dua vim tias lub qhov cua txias tau tsim nyob hauv qab txhua qhov qauv. Qhov ze-qhia qhia cov xov tooj kub uas dhau los ntawm phosphor rau hauv 3 qhov loj me li cov khoom siv. Hauv qab lub zog qis, cais cov diodes tuaj yeem pom.

Kauj Ruam 3: Kev tsim kho

Kev tsim kho yog yooj yim heev - Kuv siv daim me me (2 "x 2") ntawm daim txiag ntoo. Txuas tag nrho cov LED Anodes (+) ua ke, tom qab ntawd mus rau Liab hlau ntawm tus qauv. Ua tib yam rau Cathodes (-) thiab txuas rau lwm (dawb) xaim.

Cov xov hlau dawb uas txuas nrog txuas rau AC-mains.

Kauj Ruam 4: Teeb

Kuv coj qhov kev kho tsis raug nrog qhov sib npaug dawb teeb rau "nruab hnub". Sab laug yog nrog 50-watt halogen, thiab ntawm sab xis, nws zoo li cas nrog peb 3-watt LED "teeb". Daim duab kawg yog saib tib yam nrog lub teeb ci LED ntawm sab laug.

Txawm hais tias zoo li xiav heev, LED lub teeb pom kev zoo yuav luag zoo ib yam rau yav tav su-hnub tshav ntuj, thiab yog qhov uas peb lub qhov muag pom zoo tshaj plaws nrog. Raws li kev sim, npog ib nrab ntawm daim duab nrog ib daim ntawv thiab pom sai npaum li cas koj lub qhov muag kho qhov sib txawv ntawm lub teeb pom kev zoo.

Kauj Ruam 5: Lwm Qhov Kev Xeem Teeb Pom Kev

Thiab ntawm no, thawj daim duab hauv qab 15-W fluorescent.

Qhov thib ob nrog 3-watter, siv tib qhov raug.

Kauj Ruam 6: Lwm Yam Kev Xaiv

Chav ua lag luam no, tseem suav nrog 3-watts ntawm lub zog, raug nqi US $ 20.00. Txawm li cas los xij, qhov nqaj qauv yog qhov tseeb, yog li chav teeb pom kev tsis yog nws qhov taw tes muaj zog. Peb tuaj yeem tsim nyob rau hauv ib teev lossis ntau dua, txog li $ 10 hauv ib feem. Thiab nws muab qhov muag muag, txawm tias teeb pom kev zoo rau tag nrho thaj chaw Ib zaug ntxiv, kev nthuav tawm zoo ib yam, tsis raug kho thiab teeb tsa rau 'nruab hnub nrig'. tshuab. Ntu 1, ntu 2 thiab ntu 3. Muaj ntaub ntawv ntau ntxiv txog kev tsim cov kab hluav taws xob LED tuaj yeem pom ntawm kuv lub vev xaib no.
