4 Mahimman Fasaha na Ƙarfin Ƙarfin LED Mai Kula da Zazzabi

Aikace-aikacen kayan aikin hasken wuta mai ƙarfi na LED yana ƙara faɗi da faɗi, kuma haske mai haske na babban ƙarfin LED yana daidai da na yanzu, kuma ci gaba na LED mai ƙarfi shima zai canza tare da canjin yanayin zafi. A yau, zan dauki kowa don koyo game da dalilin LED kullin zafin jiki da LED semiconductor lighting tushen zafi hanyar. A cikin 'yan shekarun da suka gabata na ci gaba, ingancin hasken wutar lantarki na LED ya zama mafi girma kuma ya fi girma, farashin yana raguwa da ƙasa, kuma launuka sun zama masu arziki da wadata. Wannan yana sanya manyan LEDs masu ƙarfi a matsayin ingantaccen, ceton kuzari, abokantaka da muhalli, da amintaccen tushen tsaftacewa a nan gaba. Duk da haka, matsalar ɓarkewar zafi na manyan fitilun LED har yanzu babban ci gaba ne na ci gaba a aikace-aikacensa a fagen haske. Yana da dalili mai mahimmanci don ƙuntata sabon ƙarni na tushen hasken wuta. Bayanan bincike sun nuna cewa lokacin da guntuwar LED ke da haske mai haske lokacin da kullin guntu na LED ya kai 25 C, sannan idan kulli ya tashi zuwa 60 C, haskensa zai zama 90% kawai; Lokacin da kullin zafin jiki ya kai 100 C, zai ragu zuwa 80%. ; 140 C shi ne 70% kawai. Ana iya ganin cewa inganta yanayin kula da yanayin zafi yana da matukar mahimmanci don inganta ingantaccen haske. Idan ba a warware matsalar zafi mai zafi na manyan fitilun LED ba, zafin aiki na fitilun LED zai karu kuma zafin kulli zai karu, wanda zai haifar da chroma na LED, alamar ma'anar launi ta ragu, yawan zafin jiki yana ƙaruwa. , ingantaccen hasken hasken yana raguwa, kuma za a gajarta rayuwar sabis. Hasken haske mai ƙarfi na LED yana daidai da na yanzu. Idan fitarwa na gani na babban ƙarfin LED ana sarrafa shi, yana daidai da sarrafa haskensa mai haske. Ingantattun LEDs masu ƙarfi kuma za su canza tare da zafin jiki. Lokacin da zazzabi na mahalli ya wuce wani ƙima (muna kiran zazzabin aminci), ƙarfin halin yanzu na LED zai ragu ba zato ba tsammani. A wannan lokacin, idan halin yanzu ya ci gaba da karuwa, zai sa rayuwar LED ta ragu. Saboda haka, a wannan lokacin, dole ne a yi matakan da suka dace. Lokacin shigar da fitilun kumfa na halin yanzu da yanayin zafin da ke kewaye da su, ana iya sarrafa ingantaccen iko mai ƙarfi na LED a cikin lokaci. Yi amfani da fasahar ramuwa na zafin jiki don daidaita ƙarfin fitarwa na halin yanzu bisa ga yanayin yanayi, da saka idanu zafin LED a ainihin lokacin, ta yadda babban ƙarfin LED a yanayin zafi mai girma zai rage ta atomatik. 1. Matsayi na yanzu na samfuran hasken wutar lantarki mai ƙarfi na LED "chip-aluminum substrate- yanayin tsarin tsarin Layer uku" ana amfani da shi ta mafi yawan manyan na'urorin hasken wutar lantarki na LED akan kasuwa na yanzu, wato, guntu na farko akan abubuwan aluminum. don samar da na'urar hasken wutar lantarki ta LED, sannan sai a shigar da tsarin hasken hasken a kan radiyo ta yadda za ku iya yin babban hasken wutar lantarki na LED. A halin yanzu, farkon amfani da LEDs don nuna fitilu da alamomi ana amfani dashi azaman tsarin kula da thermal don manyan LEDs. Wannan yanayin sarrafa thermal yana iyakance ga ƙananan amfani da LED. Hasken wutar lantarki mai ƙarfi na LED wanda aka shirya ta hanyar tsarin tsari guda uku, har yanzu akwai wurare da yawa marasa ma'ana dangane da tsarin tsarin, kamar babban kulli zafin jiki, ƙarancin ƙarancin zafi, ƙarin juriya na thermal a tsakanin tsarin, ƙarancin ƙarancin zafi, ingantaccen yanayin zafi, ƙarin juriya na thermal lamba Sakamakon haka, zafin da guntu ya fitar ba zai iya tarwatsewa da fitar da shi yadda ya kamata ba, yana haifar da faɗuwar hasken LED, ƙarancin haske, da gajeriyar rayuwa. Saboda gazawar abubuwa da yawa kamar tsari, farashi, da amfani da wutar lantarki, babban ƙarfin wutar lantarki na LED yana da wuyar ɗaukar tsarin kashe zafi mai aiki, kuma yana iya ɗaukar tsarin lalatawar zafi kawai, amma ƙarancin zafi mai ƙarfi yana da babban gazawa; kuma tasirin canjin makamashi na yanzu na LEDs har yanzu yana da tasiri Ba mai girma ba, kusan 70 % na ikon shigar da wutar lantarki za a iya canza shi zuwa zafi, koda tasirin hasken ya karu da 40%, ana canza makamashin zuwa zafi, wato, shi ne. yana da wuya a ƙara yawan digiri na zafi ba tare da la'akari da zafi ba. 2. Halayen tushen hasken wutar lantarki na LED sun bambanta da fitilun fitilun gargajiya, fitilu masu ƙyalli, da fitilun halogen. LED semiconductor haske kafofin hasken wuta an yi su da semiconductor abu kuma kunsha PN. Acupoints-ƙasa na lantarki suna haifar da haske mai gani ta hanyar haɗakarwa, jagorar PN mai kyau Tong, yanke baya, wanda yankin N yayi daidai da wutar lantarki mara kyau, kuma yankin P ya dace da madaidaicin sanda.

Gabatarwar zafin kullin LED 3.1 Abin da ke haifar da zazzabin LED da zazzabin LED ya haifar shi ne saboda makamashin da aka ƙara ba duka ake canza su ta hanyar makamashin haske ba, kuma wasu daga cikinsu an canza su zuwa makamashin thermal. A halin yanzu, ingancin haske na LED akan kasuwa shine kusan 100 LM / W. A wasu kalmomi, kusan kashi 70% na makamashin lantarki ana lalacewa ne ta hanyar makamashin thermal. Gabaɗaya magana, akwai abubuwa guda biyu waɗanda ke haifar da samar da zafin kullin LED. Ƙayyadaddun kamar haka: 1) Ƙimar ƙididdiga ta ciki. Lokacin da acupuncture da na'urar lantarki suka haɗu, ba za su iya samar da photon ba. Ana kiran wannan yawanci "leakage na yanzu", wanda shine dalilin da yasa aka rage yawan adadin abubuwan da ake ɗauka na yankin PN. Wutar lantarkin da aka zube da kuma na yanzu shine ikon watsawa na wannan bangare, wato canzawa zuwa makamashin thermal, amma wannan bangare ba shine babban bangaren ba, saboda fasahar zamani na iya sanya ingancin photon na LED na ciki kusa da 90. %. 2) Kimanin kashi 30% na ingancin jimla na waje. Daya daga cikin manyan dalilan shine cewa photons da loadmons ke samarwa ba za a iya canza su zuwa waje na guntu ba amma sun juya zuwa zafi.
