Saddex guul darrooyinka caadiga ah ee nalalka calaamadaha LED iyo xalalka

Qaar ka mid ah asxaabta waxay waydiiyaan sababaha caadiga ah iyo hababka daawaynta ee nalalka iftiinka LED-ka, iyo dadka qaarkiis waxay rabaan inay waydiiyaan sababta nalalka iftiinka LED-ka aysan iftiimin.Maxaa dhacaya?Dhab ahaantii, waxaa jira saddex guuldarro oo caadi ah iyo xalalka nalalka calaamadaha.

Saddex guul darrooyinka caadiga ah ee nalalka calaamadaha LED iyo xalalka:

Ciladda caadiga ah waa cilladda toosiyaha.Aad magaalada iftiinka oo mid iibso oo beddel.Leedhka oo dhan dhif ayuu u dhaawacmaa.

Laba.Sababaha iftiinka isha ee isha:

1. Kuulka laambada iyo awoodda wadista ledhku isma dhigmaan, kuwa caadiga ah ee 1W kuul leh: 280-300 ma hadda iyo: 3.0-3.4V, haddii chip laambadku aanu lahayn awood ku filan, waxay keeni doontaa in isha iftiinka ay istaagto. ifafaale, haddii hadda uu aad u weyn yahay, kuulka laambaduhu ma awoodi doonaan inay u adkeystaan ​​beddelka.Xaaladaha daran, fiilooyinka dahabka ama naxaasta ah ee kuulku waa gubi karaan, taasoo keenaysa in uluhu ay shaqayn waayaan.

2. Waxaa laga yaabaa in sahayda korontada ay dhaawacdo, marba haddii aad ku bedesho koronto kale oo wanaagsan, ma libiqi doonto.

3. Haddii darawalku leeyahay shaqada ilaalinta heerkulka xad-dhaafka ah, waxqabadka kuleylka kuleylka ee nalka calaamada LED ma buuxin karo shuruudaha, iyo ilaalinta heerkulka xad-dhaafka ah ee darawalku wuu liqi doonaa marka uu bilaabo inuu shaqeeyo.Tusaale ahaan, guryaha 20 w ee saadaasha nalalka loo isticmaalo in lagu ururiyo nalalka 30W ma qabtaan shaqo fiican oo qaboojin ah.

4. Haddii nalalka dibadda ay sidoo kale leeyihiin ifafaale stroboscopic, waxay ka dhigan tahay in nalalka daadku.Natiijo ahaan, haddii uu libiqsado, ma shido.Ilayskii iyo dirawalkii way jabeen.Haddii darawalku uu sameeyo shaqo fiican oo ah ilaalinta biyaha, tusbaxa laambaduhu wuu jabaa oo isha iftiinka waa la bedeli karaa.

Saddex.Habka biligleynta iftiinka ishaarada:

1. Codsiyada nalalka LED-ka ee tamarta yar ee khadka-ka-baxsan, awoodda guud ee korka sare waa dusha sare ee duulista ee go'doonsan.Dot-ka Cagaaran, 8W darawalka tooska ah ee LED, wuxuu la kulmaa tamarta Star heerarka iftiinka gobolka.Xaaladda naqshadeynta, sababtoo ah beddelka awoodda mawjadda labajibbaaran ee sinusoidal ee maamulaha duulista ma bixinayo tamar joogto ah eexda aasaasiga ah, wareegga is-xakamaynta firfircoon ayaa laga yaabaa inuu dhaqaajiyo oo uu keeno iftiinka iftiinka.Si looga fogaado dhibaatadan, waxaa lagama maarmaan ah in la sameeyo dareeraha aasaasiga ah ee ka baxsan wareegga badhkii kasta.Sidaa darteed, waxaa lagama maarmaan ah in si sax ah loo doorto awoodda iyo qiyamka caabbinta ee nalalka calaamadaha LED ee ka kooban wareegga.

2. Caadiyan isha bini'aadamku waxay dareemi kartaa lilicka iftiinka inta jeer ee 70 Hz, laakiin in ka badan ma awoodo.Sidaa darteed, codsiyada nalalka LED-ka, haddii calaamadda garaaca wadnaha ay leedahay qayb soo noqnoqota hoose oo leh soo noqnoqoshada ka hooseeya 70 Hz, isha bini'aadamku waxay dareemi doontaa liiqaq.Dabcan, waxaa jira arrimo badan oo keeni kara nalalka LED-ka inay ku biligleeyaan codsi gaar ah.

3. filtarrada Emi ayaa loo baahan yahay xitaa codsiyada wadista horseedka ah ee bixiya hagaajinta qodobka awoodda wanaagsan iyo taageerida dhimista saddex-geesood ee labada jiho ee SCR.Hadda ku-meel-gaadhka ah ee ay keentay tallaabada wareegga saddex-geesoodka ah ee SCR-du waxay kicisaa dhawaaqa dabiiciga ah ee inductors iyo capacitors ee shaandhada emi.

Haddi sifada sanqadhigu ay keento in wax gelinta hadda ka hooseeyo haynta hadda ee saddex-geesoodka laba-jiho ee SCR curiyaha, saddex-geesoodka saddex-geesoodka ah ee SCR-da waa la damin doonaa.Dib u dhac gaaban ka dib, qaybta bedelaadda saddex-geesoodka ah ee SCR waxay caadi ahaan shidmi doontaa mar kale si ay u kiciso isla dhawaaqii hore.Dhacdooyinkan taxanaha ah waxaa laga yaabaa in lagu soo celiyo marar badan wareega badhkii ee qaabka mowjadda korantada INPUT ee semaphore-ka LED, taas oo keentay in la arki karo LED.
