Hluav Taws Xob Hluav Taws Xob Hlau Lub Teeb Nrhiav Kev Tswj Kub Thiab Kub Tswj Dej
Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hlau yog ib feem ntau siv vuam cov cuab yeej uas emits ua tshav kub thaum ua haujlwm. Nws tsuas yog ua kom sov li tsis emitting teeb. Yog tias tus neeg siv tsis tau ua kom sov nws, lawv yuav tsis paub tias nws ua haujlwm nrog hluav taws xob; Qee lub sij hawm tsis nco qab mus rau unplug lub hwj chim ntsaws raws li qhov chaw pov tseg hluav taws xob, thiab sijhawm tawg yooj yim, nws tuaj yeem ua rau muaj kev sib tsoo hlau. Qee lub sij hawm nws yog qhov tsim nyog los txo qhov kub ntawm solding hlau me ntsis kom tsis txhob muab ntsaws rau hauv thiab unplugged, uas yog qhov teeb meem heev. Rau cov teeb meem saum toj no, lub Circuit Court qhia nyob rau hauv daim duab nrog daim duab txuas tau los txhim kho.
Thaum cov hlau soldering rau, qhov zoo ib nrab ntawm lub zog khoom tsim hluav taws xob ua rau cov hluav taws xob hluav taws xob ua rau muaj hluav taws xob d2, d3, thiab d4 vim qhov tam sim no. Lub teeb LED ntawm D1 thiab tam sim no lim cov resistortor r; Ntawm qhov tsis zoo ib nrab puag ncig (thaum hloov k raug kaw), qhov tam sim no hla dhau deg. Vim yog lub Volfage poob ntawm Diode tsuas yog 0. 7V, nws yog qhov tsis zoo rau kev siv cov hlau solding. Yog tias hloov mus K yog discuit Court, lub Circuit Court yuav nyob hauv ib nrab Wave Fais Fab Lub Xeev, thiab qis dua nyob rau hauv tam sim no yuav ua rau kub ntawm solding hlau kom poob. Qhov no tsis yog txo qis kev siv hluav taws xob tab sis kuj ua tiav lub hom phiaj ntawm kev tswj hluav taws kub. Ib qho ntxiv, D1 thaiv cov kev thim rov qab ntawm lub zog hluav taws xob, yog li tiv thaiv tus LED. Tag nrho cov Circuit Court yog yooj yim heev, nrog cov nqi tiv thaiv tsawg thiab tsis muaj kev tshwj xeeb. Nws tsis yog qhov nyuaj rau cov neeg xav kho kom rov ua dua tshiab. D hauv Circuit Court yog 1n4007. R siv ib 1 / 4w resistor. Vim tias tam sim no ntawm 1N4007 yog 1a, lub load tam sim no yuav tsum tsis pub tshaj tus nqi no. Hmoov zoo, feem ntau yog siv 20W lossis 35W Soldering Irons tsis tuaj yeem ncav cuag tus nqi no. Tsis tas li, nws yuav tsum raug sau tseg tias Circuit Court tsuas yog haum rau soldering irons thiab tsis yog rau incandescent teeb.
