Dab tsi yog kev ceev faj rau kev siv LED?

1) Vim tias qhov ua haujlwm voltage ntawm LED hloov pauv los ntawm 0.1V, qhov ua haujlwm tam sim no yuav hloov li ntawm 20mA. Rau kev nyab xeeb, nyob rau hauv ib txwm muaj xwm txheej, series tam sim no limiting resistors yog siv, thiab lub zog loj poob yog obviously tsis haum rau lub hnub ci lawn teeb, thiab lub brightness ntawm LED hloov nrog lub khiav hauj lwm voltage. Kev siv hluav taws xob hluav taws xob yog ib txoj hauv kev zoo, koj tuaj yeem siv qhov yooj yim tsis tu ncua tam sim no Circuit Court, luv luv, yuav tsum cia li txwv qhov tam sim no, txwv tsis pub nws yuav ua rau LED puas.

2) Lub ncov tam sim no ntawm cov dav dav LED 50 ~ 100mA, rov qab voltage txog 6V, ceev faj kom tsis txhob dhau qhov kev txwv no, tshwj xeeb tshaj yog nyob rau hauv lub hnub ci rov qab kev twb kev txuas los yog roj teeb tsis muaj load, booster Circuit Court ncov voltage siab dhau lawm, yog yuav Tshaj qhov kev txwv no, ua rau lub LED puas.

3) LED cov yam ntxwv kub tsis zoo, qhov kub thiab txias nce los ntawm 5 ° C, lub luminous flux poob los ntawm 3%, them sai sai rau kev siv lub caij ntuj sov.
4) Kev ua haujlwm voltage dispersion yog loj, tib qauv, tib batch ntawm LED ua hauj lwm voltage muaj ib tug tej yam txawv, yuav tsum tsis txhob siv nyob rau hauv series. Yuav tsum tau siv nyob rau hauv parallel, yuav tsum xav txog tam sim no sib koom.

5) Ultra-ci dawb LED xim kub yog 6400k ~ 30000k. Tam sim no, ultra-ci dawb LED nrog qis xim kub tsis tau nkag mus rau hauv kev ua lag luam, yog li lub hnub ci lawn teeb ua los ntawm ultra-ci dawb LED muaj kev nkag mus tsis zoo, yog li them sai sai rau qhov tsim kho qhov muag.

6) hluav taws xob zoo li qub muaj kev cuam tshuam zoo rau ultra-ci dawb LED, thiab cov chaw tiv thaiv zoo li qub yuav tsum tau teeb tsa, thiab cov neeg ua haujlwm yuav tsum hnav lub dab teg tiv thaiv zoo li qub. Lub ultra-ci dawb LED puas los ntawm hluav taws xob zoo li qub yuav tsis pom ntawm lub qhov muag thaum lub sijhawm ntawd, tab sis lub neej kev pabcuam yuav luv dua.
