Isense resistors siv yog ob 0.47R ua ke, muab tus nqi kwv yees li 0.23R. Koj tuaj yeem siv tus nqi sib txawv tab sis nco ntsoov tias koj hloov kho nws qhov txiaj ntsig hauv qhov haujlwm. Nco ntsoov tias lawv muaj lub zog txaus ntsuas rau 3A.

ADC = Idrive*Rsense*1023/1.1

Kauj Ruam 3: Txuas 3A Hloov LED Tsav Tsheb

Kev hloov pauv LED tsav tus qauv tau xaim sab nraud rau nws PWM qhov chaw. Txij li nws ua haujlwm ntawm qhov ntau zaus, suab nrov yog qhov teeb meem uas txhais tau tias tus tsav tsheb lub tswv yim xaim yuav tsum tau ntswj nrog nws cov xaim av. Qhov no tiv thaiv kev khaws cov suab nrov uas cuam tshuam rau kev nyeem ntawv, txo qhov tsav tam sim no qhov raug.

Ib txoj hauv kev uas tuaj yeem zam qhov xav tau los ntswj cov xov hlau yog txhawm rau nruab Isense resistor ntawm lub microcontroller module hloov chaw.

Kauj Ruam 4: Txoj Haujlwm

Cov LEDs yuav tsum tau nyob deb txaus kom tiv thaiv cov iav los ntawm kev sib kov. Yuav ua li cas kua nplaum tau siv los lo cov iav. Lub tsheb kauj vab tsom iav tau txuas rau nws.

Kauj Ruam 6: Sib Sau Amber Lub Tsev Teeb

Sib dhos Amber Lub Tsev Teeb

Hlau cov LEDs kom lawv nyob hauv 2P3S teeb tsa. Plaub LEDs tau tsom mus rau 0 ° thiab ob ntawm 45 °. Yog tias koj muaj txoj hlua tuav ncaj los yog riser, koj tuaj yeem muaj peev xwm tsom lawv 90 ° yam tsis muaj kev cuam tshuam. Koj tuaj yeem sim nrog cov haujlwm sib txawv xws li lub taub hau raj, qhov kawg ntawm lub raj lossis cov tee dej. Koj tuaj yeem sim ua lub hom phiaj ob nrab ntawm 0 thiab 45 ° txhawm rau txhim kho kev pab them nqi. Kub kua nplaum rau chav nyob rau qhov nyem nyem thiab kom cov LEDs txav mus los.

Ib daim npog acrylic tau teeb tsa ntawm 3A lub tsheb kauj vab teeb rau kev tiv thaiv.

Cree XPL High-Intensity LEDs tau siv kom nqaim nqaim thiab elliptical beam optics tuaj yeem siv tau.

2 lub xov tooj ntawm tes 26650 roj teeb tau siv los ua ib qho thaiv rau cov laug cam.

Ib lub xov tooj 3 ntawm 18650 lub roj teeb nrog cov pins sib npaug tau siv. Ib qho 3 lub xov tooj sib txuas sib txuas, tus tuav lub fuse, thiab cov txuas hluav taws xob tau muab muag rau cov koob. Qhov no tso cai sib npaug them yam tsis tas yuav tshem cov cell los ntawm tus tuav txhua lub sijhawm koj them nws.

Cov khoom siv hluav taws xob thiab lub roj teeb tau txuas rau ntawm lub lauj kaub tais diav nrog cov hlua velcro. Txoj kev no txuag chav rau kev sib tw piv rau kev teeb tsa lawv mus rau tus ncej. Cov xov hlau rau lub teeb tau txuas rau lub raj saum toj.

Ob lub khawm tau nyob ntawm tus tuav lub roj teeb.

Kauj Ruam 8: Kev Xaiv Lwm Yam Kev Xaiv: Sab Tube
