Tsim koj li 18W LED lub teeb ci los tawm tsam lub caij ntuj no nyuaj. Lub teeb ci no nthuav dav thiab dimmable siv PWM. Yog tias koj muaj lub teeb timer, koj tuaj yeem siv nws ua lwm txoj hauv kev rau lub tswb tswb.
Kauj ruam 1: Cov ntaub ntawv
LightBox
- 6 x 3W dawb LED
- Heatsink
- Lub thawv hlau
- on-off hloov

Kauj Ruam 2: Kuv Yuav Tsum Muaj pes tsawg LEDs?
10,000, lux feem ntau siv rau lub teeb dawb. Qib qis qis yog qhov muaj txiaj ntsig, txawm hais tias koj xav tau sijhawm ntev dua. Rau lub teeb ntsuab, 350 lux yog sib npaug rau 10, 000 lux ntawm lub teeb dawb. Ib lux yog sib npaug rau 1 lumen ib square meter. Nco ntsoov tias diffusers tseem thaiv lub teeb. Lux meter yuav pab tau.
Lux/Lumen Converter
Kauj ruam 3: LED tsav tsheb
Kuv siv tus tsav tsheb no vim nws tso cai rau PWM dimming. Rau lub zog hluav taws xob hluav taws xob siab dua 15 volts, lub rooj vag thiab 555 timer yuav xav tau tus tswj hluav taws xob. Koj tuaj yeem siv LM7812.
Kauj Ruam 4: Mount LEDs rau Heatsink
Mount cov LEDs nrog epoxy.
Kauj Ruam 5: Txiav Qhov Hauv Lub Thawv
Txiav qhov rau DC lub hwj chim txuas, ntsia hlau, hloov, lub zog, thiab lub rhaub dej kub.
Kauj Ruam 6: Txiav Square rau Npog
Kauj Ruam 7: Txuas Diffuser rau Lub Hau
Txiav lub diffuser rau qhov loj me thiab laum mounting qhov ntawm ob lub hau hlau thiab cov ntawv txheeb.
Kauj Ruam 8: Xuab Zeb Sab Hauv Ntawm Lub Thawv
Kauj Ruam 9: Ntxuav Lub Thawv Hlau
Ntxuav lub thawv nrog xab npum thiab dej kom tshem tawm cov hlau txhuam.
Kauj Ruam 10: Mount Cheebtsam rau Lub Thawv
Mount lub rhaub dej kub, hloov pauv, thiab DC fais fab txuas nrog epoxy putty.
Kauj Ruam 11: Txaus siab rau "Tshav Ntuj"
