Scope ntawm LEDs hnub no yog loj loj thiab lossi expanding. Tab sis tsis yog li ntawd ntev dhau los, qhov no ntaus ntawv yuav tsum pom xwb nyob rau hauv cov zaub schemes. Nws twb tsis tsim rau hnyav loads. Tsim puas haib dua li uas yuav ua hauj lwm nyob rau hauv lub teb ntawm teeb pom kev zoo. Muaj spotlights thiab teeb raws li nyob rau hauv high-power LEDs. Lawv yog siv nyob rau hauv lub tsheb lag luam, yog muab kev koom tes nyob rau hauv lub tsheb lub teeb thiab tswj lub tsheb khiav nrog haib tsheb teeb. Muaj cov khoom siv uas yog ib tug zoo analogue ntawm cov uas twb teeb pom kev zoo pab kiag li lawm. LED teeb pib tshwm nyob rau hauv peb qhov, stairwells thiab chaw ua hauj lwm.
Lub txawv txawv thaj chaw ntawm LEDs tau ntev attracted tus mloog ntawm designers. Nyob rau hauv lub automotive kev lag luam yog siv sab teeb thiab nres teeb rau lub hauv paus ntawm cov pab kiag li lawm. Ib tug ntawm cov tiam sis nyob rau hauv lub tsheb tsim yog los hloov cov obsolete qhov muag rau LEDs hauv lub alarm. Lawv kuj tau lug siv rau zaub rau lub twj paj nruag vaj huam sib luag thiab sab hauv teeb pom kev zoo. Smooth rau lub LED - nws yog ib tug ntawm cov feem ntau pheej ntsiab rau lub tsheb nyob. Piv txwv li, lub teeb nyob rau hauv lub neeg nrog caij compartment yuav ua tau zoo rau lub teeb los yog hluav taws tua, feem los ntawm qhib los yog kaw lub qhov rooj. Los yog teeb rau cov kev tswj pab kiag li lawm yuav tsum ntseeg nkaws muab rau / tawm raws li qhov ua kom muaj ib tug ntaus ntawv, piv txwv li, seem illumination.
Npaj tus kev koom ua ke ntawm LEDs yog ib qho yooj yim, nws yog tsim nyog los sib sau ua ke ib tug me me Circuit Court. Yog hais tias lub hwj chim tau ntawm lub load yog me me, koj muaj peev xwm siv ib tug yooj yim ncov qaumteb qabteb capacitor, solder nws nyob rau hauv thaum uas tig mus rau ib tug teeb pom kev zoo ntaus ntawv. Tsis txhob hnov qab polarity (qhov zoo davhlau ya nyob twg ntawm cov capacitor yuav tsum tau kev cob cog rua rau lub anode ntawm lub LED neeg xyuas pib). Tsis zoo, ntsig txog, rau lub cathode. Lub capacitor yuav tawg yog hais tias tsis zoo kev cob cog rua! Tsis tas li ntawd xyuam xim rau cov nyiaj pab ntau tshaj voltage ntawm uas ua hauj lwm xws li ib tug tswvyim. Nws yuav tsum tsis pub tshaj tus permissible lag luam voltage ntawm lub capacitor.
Kom sau tswvyim, koj yuav tam sim ntawd pom tus mos pib LEDs. Capacitance yog tsis pom zoo kom ua rau kom ntau tshaj 2,200 microfarads, txij li thaum tau siab tshaj cov nqi no yuav ua rau ceev ceev coj ntawm lub Switchgear. Qhov tseeb yog tias thaum ua ntawv thov mus rau lub Circuit Court voltage, capacitance pib them. Nyob rau hauv ib tug thawj lub sij hawm, muaj ib tug dlej starting tam sim no, uas yuav ua kev puas lub relay hu. Qhov saum toj no capacitor kom du koom ua ke ntawm LED nrog ib lub sij hawm ncua sij hawm ntawm 3-5 vib nas this. Nws yog exponential, uas yog, chiv koj tau txais txog 20-40 feem pua ntawm cov teeb pom kev zoo nyob rau hauv lub hav zoov. Rau ib ob peb lub vib nas this tom qab hais tias muaj yog ib tug tus incorporation ntawm lub LEDs mus rau lub nominal hom kev lag luam.
Mus ua hauj lwm nrog ntau haib illumination pab kiag li lawm ntawm lub capacitor yog tsis txaus. Du rau xws li ib lub koom haum los ntawm circuits uas tswj lub LED lub tswv yim tam sim no tso zis theem, ua ke, piv txwv li, transistors. Qhov kev ncua lub sij hawm nyob rau hauv cov ntaub ntawv no yog siv nyob rau hauv ntau yam hluav taws xob circuits.
