Zaɓi Ƙwararrun Chip Tushen Hasken LED

An ɓullo da farashin na'urori masu haske na LED a nan gaba kaɗan, kuma LEDs an san su da yawa a matsayin kore da tsabtace tsabtace muhalli. Maɓuɓɓugan hasken LED suna da tsawon rayuwar sabis, tanadin makamashi da ceton wutar lantarki, aikace-aikacen mai sauƙi da dacewa, da ƙarancin amfani. Saboda haka. Tun a shekarar 2008, jigilar kujerun fitilun gida a duk shekara a duniya ya kai yuan biliyan 50. Fasahar hanyoyin hasken LED ta ƙara girma, kuma hasken kowane tayal ya karu cikin sauri, wanda ya sa ya rage farashin kowace shekara. Babban kasuwa da ci gaba da buƙatun ci gaba na fitilun kore na LED za su zama babbar kasuwar tsunami a cikin masana'antar da'ira mai hade bayan VCD, DVD, wayoyin hannu, da MP3! Mafi kyawun aikin ceton makamashi mai ƙarfi, tsawon rai, da kariyar muhalli na fitilun LED gabaɗaya ana gane su. 1. LED high makamashi -ceton: DC direban, ultra-low ikon amfani (guda guda tube 0.03 1W) Electric ikon canza wutar lantarki yana kusa da 100, wannan haske tasiri ne fiye da 80% karin makamashi -ceton fiye da gargajiya haske kafofin. 2. LED tsawon rai: LED haske tushen ana kiransa Longevity haske. Maɓuɓɓugan hasken sanyi masu ƙarfi, marufi na resin epoxy, kuma babu sassaka sassa a jikin fitilar. Babu gazawa kamar hasken filament, nutsewar zafi, da saurin haske. Fiye da ya fi. 3. Kariyar Kariyar Muhalli na LED: LED shine tushen hasken kore, kuma fa'idodin kare muhalli sun fi kyau. Babu ultraviolet da infrared haskoki a cikin bakan, ƙananan adadin kuzari da walƙiya kyauta, babu radiation, da sharar gida za a iya sake yin amfani da su. Babu gurɓata ba tare da mercury ba, tushen hasken sanyi, wanda za'a iya taɓa shi lafiya. Nasa ne na asalin tushen hasken wuta. Halayen aikin ƙirar tushen hasken LED suna da ƙasa sosai a cikin ƙarfin VF na tushen hasken LED. A yawancin, 2.75 3.8V ne. Saboda haka, ƙarfin fitarwa na LED drive IC shine VFXN ko VFX1, kuma IF yana ci gaba da gudana a 15 1,400ma. Madogarar hasken LED da fitilun LED ke amfani da ita yana da nau'ikan guda biyu: ƙaramin ƙarfi (IF shine 15 20mA) da ƙarfin ƙarfi (IF mafi girman 200mA). Ana amfani da ƙananan wutar lantarki mafi yawa azaman fitilun hasken rana na LED, fitulun ado, da fitilun gasa. Ana amfani da LED mai ƙarfi don hasken iyali, fitilu, fitilun ƙasa, fitilun bango, fitilun titi, fitilun rami, fitilun aikin mota, da sauransu. Madogarar hasken wutar lantarki na LED ƙananan ƙarfin lantarki ne kuma babban na'urar da ke motsawa a halin yanzu. Ƙarfinsa mai haske yana ƙayyade ta halin yanzu yana gudana ta cikin LED. A halin yanzu zai haifar da hasken LED attenuation, kuma na yanzu ya yi ƙanƙanta zai shafi ƙarfin haske na LED. Sabili da haka, direban LED yana buƙatar samar da wutar lantarki ta yau da kullun don tabbatar da amincin manyan LEDs masu ƙarfi, kuma a lokaci guda cimma ingantaccen ƙarfin hasken wuta. A fagen hasken wutar lantarki, don yin la'akari da halaye na ceton hasken wutar lantarki na LED da tsawon rai, yana da mahimmanci a zaɓi direban LED IC daidai. Ba tare da madaidaicin direba na IC ba, ba za a iya nuna fa'idodin hasken LED ba. LED-gefen haske Madogararsa LED allura gyare-gyare module LED haske tsiri LED waterproof ban ruwa manne module Hongyan gida uku -daya gida LED haske module bukatun ga low-ƙarfin lantarki tuki kwakwalwan kwamfuta ya kamata a hadu da maras muhimmanci shigar ƙarfin lantarki kewayon tuki guntu, DC 8 40V, don rufe manyan buƙatun aikace-aikacen. Ikon yin tsayayya da matsa lamba ya fi 45V. Lokacin da shigarwar ta kasance AC 12V ko 24V, ƙarfin lantarki mai sauƙin gyara gada zai canza tare da ƙarfin wutar lantarki, musamman lokacin da ƙarfin lantarki ya yi girma, ƙarfin wutar lantarki na DC zai yi girma. Idan IC ɗin tuƙi ba shi da kewayon ƙarfin shigarwa mai faɗi, sau da yawa za a shiga shi lokacin da ƙarfin wutar lantarki ya tashi, ta haka yana ƙone tushen hasken LED. 2. Nau'in fitarwa na yanzu na guntun tuƙi yana buƙatar fiye da 1.2 1.5A. A matsayin tushen hasken LED don haskakawa, ƙarancin halin yanzu na tushen hasken wutar lantarki na 1W shine 350mA, kuma aikin na yanzu na tushen hasken LED na ikon 3W shine 700mA. Maɓuɓɓugar hasken LED tare da babban iko na buƙatar babban halin yanzu, don haka direban IC da aka zaɓa ta na'urorin hasken LED dole ne ya sami isasshen fitarwa na yanzu. Lokacin zayyana samfurori, dole ne a yi amfani da aikin direba na IC don yin aiki a 70-90% na mafi kyawun yanki na 70-90% na cikakken kayan aiki. Driver ICs ta amfani da cikakken kayan fitarwa na yanzu ba a bazuwa ba a cikin ƙaramin sarari na fitilun, wanda zai iya haifar da gajiya da farkon gazawar fitilar. 3. Dole ne a kiyaye abin da ake fitarwa na guntu mai tuƙi akai-akai, ta yadda LED ɗin zai iya haskakawa a tsaye ba tare da walƙiya ba. Ana amfani da nau'in nau'in kwakwalwan kwamfuta iri ɗaya a ƙarƙashin yanayi iri ɗaya, kuma abin da yake fitarwa ya kamata ya kasance daidai gwargwadon yiwuwar, wato, hankali dole ne ya zama ƙanƙanta, ta yadda zai iya tabbatar da inganci da tsari yayin samarwa akan adadi mai yawa na sarrafawa ta atomatik. layuka. Domin wani m guntu tare da wani bayyana halin yanzu fitarwa, shi wajibi ne don zaɓar zaɓi a gaban masana'anta ko sanya shi a cikin samar line, daidaita juriya darajar halin yanzu saitin juriya a kan PCB jirgin, don haka da cewa. fitilun LED - madaidaicin allon tuƙi na yau da kullun da kwamitin PCB ke samarwa Haske da haske na tushen hasken ya dace don kiyaye daidaiton samfurin ƙarshe.
