Siv LED Tshuaj Yej Teeb los Tsav Cov Hluav Taws Xob LED tam sim no uas yooj yim thiab yooj yim los ua.
Tsim cov phiaj xwm uas tsim qhov tseeb tiag saib cov tswm ciab-nplaim hluav taws yog qhov nyuaj ua kom tiav. Kuv xav ua txoj hauv kev yooj yim thiab nrawm los tsav cov LED tam sim no yam tsis muaj kev ua haujlwm nyuaj. Kuv tau saib ntawm LED Tea Light ntawm Michael's Crafts Store thiab qhov kev paub tau los rau kuv vim li cas kuv thiaj li tsis yog kuv tsuas yog txuas lub teeb LED Tshuaj Yej Teeb mus rau lub tshuab hluav taws xob uas tuaj yeem ua haujlwm siab dua tam sim no los tsim lub zog LED tam sim no. Qhov nyuaj ntawm kev tsim hluav taws xob tau ua tiav los ntawm kev yuav khoom ntawm LED Tea Light uas raug nqi ob peb daus las.
Kauj Ruam 1: Sib nrug TheTea Teeb
Txhawm rau qhib Cov Tshuaj Yej Teeb koj txiav nrog rab riam 1/2 hauv qab los txog rau thaum koj txiav los ntawm cov yas ces sab saum toj yuav tawm. Cov xaim no yuav ua rau lub ntsej muag ci ntawm tus neeg tsav tsheb tam sim no. Txhawm rau nrhiav qhov ntxiv (+) sab ntawm LED cov hlau lead yog siv cov ntsuas ntsuas ntau nrog cov Tshuaj Yej Teeb qhib. yog li peb muaj ib qho kev sib txuas hauv av. Hauv daim duab liab hlau yog (+) thiab cov xaim dawb yog lub roj teeb tsis zoo.

Kauj Ruam 2: Tsim Circuit Court
Cov Tshuaj yej Teeb ua pseudo random flickering nplaim hluav taws xob los ntawm kev sib txawv ntawm qhov hluav taws xob thiab tam sim no ntawm LED. Cov Tshuaj Yej Teeb LED (+ Anode Lead) tso tawm tam sim no ntawm BJT transistors ua rau cov LED tso tawm. Txhawm rau ua kom cov zis LED flicker koj yuav tsum hloov kho qhov sib txawv resistor R1 thiab R2 rau txoj haujlwm kom tsis txhob saturate cov transistors tso tawm.
tab sis ua kom LED lub flicker zoo li Cov Tshuaj Yej Teeb LED. Qhov pib zoo rau R1 yog 50K ohms thiab R2 yog 20K ohms. Tus tsav tsheb LED 2N3906 muaj IC siab tshaj ntawm 200mA thiab tuaj yeem hloov pauv nrog PN2907 rau IC siab tshaj ntawm 800mA. Tus resistor Rx tuaj yeem hloov pauv los tswj qhov tam sim no thiab qhov hluav taws xob los ntawm cov zis LED. Kuv siv 471 ohms rau Rx los tsim qhov siab tshaj tam sim no ntawm 25mA hauv txhua LED. Koj tuaj yeem teeb tsa ntau ntu ntu tsav tsheb ua ke los tsim ntau lub lumens ntawm lub teeb ci. Kev tsim hluav taws xob tsim hluav taws xob ua kom pom cov tswm ciab kom ua rau lub siab LED tam sim no, lwm qhov siab tam sim no, lossis HBLED, thiab lwm yam.
