Machubu a fluorescent amagwiritsidwa ntchito kwambiri pamoyo watsiku ndi tsiku, monga masitolo akuluakulu, masukulu, mizinda ya maofesi, misewu yapansi panthaka, ndi zina zotero. mukhoza kuona nyali zambiri za fulorosenti m'malo aliwonse owonekera! Ntchito yopulumutsa mphamvu komanso yopulumutsa mphamvu yaNyali za fulorosenti za LEDwakhala akudziwika kwambiri ndi aliyense pambuyo pa kulengeza kwa nthawi yaitali. Komabe, ambiriMachubu a fluorescent a LEDogulidwa pamtengo wapamwamba tsopano ali mumkhalidwe wofanana ndi nyali zotsika mtengo zopulumutsa mphamvu: kupulumutsa mphamvu koma osati ndalama! Ndipo ndi kuwononga kwambiri ndalama. Momwe mungapangire moyo wautumiki ndi kuwala kwa LED kufika pamlingo wokhutiritsa ogwiritsa ntchito ndi mutu watanthauzo! Pofuna kukhalabe ndi moyo wautali wautumiki komanso kuwala kwakukulu, machubu a fulorosenti a LED amayenera kuthetsa matekinoloje anayi ofunika: magetsi, gwero la kuwala kwa LED, kutaya kutentha ndi chitetezo.

1. magetsi

Chofunikira chachikulu chamagetsi ndikuchita bwino kwambiri. Kwa mankhwala omwe ali ndi mphamvu zambiri, kutentha kochepa kumapangitsa kuti pakhale bata. Nthawi zambiri, pali njira ziwiri zopangira magetsi: kudzipatula komanso kusadzipatula. Voliyumu yodzipatula ndi yayikulu kwambiri ndipo mphamvu zake ndizochepa. Mukagwiritsidwa ntchito, padzakhala zovuta zambiri pakuyika, zomwe sizodalirika ngati zomwe sizidzipatula.

2. Gwero la kuwala kwa LED

TheNyali ya LEDmikanda yokhala ndi setifiketi ya ma lemmings aku Taiwan imagwiritsidwa ntchito. Chipcho chimayikidwa pa pini, ndipo mphamvu ya kutentha imadutsa pa pini ya siliva kuti itulutse mwachindunji malo otentha opangidwa ndi chip node. Ndiwosiyana kwambiri ndi zinthu zachikhalidwe zapamzere ndi zida zachikhalidwe za chip potengera kutentha. Kutentha kwa node kwa chip sikungadziunjike, motero kuonetsetsa kuti mikanda ya nyali yowunikira ikugwiritsidwa ntchito bwino, kuonetsetsa moyo wautali wa mikanda yowunikira nyali ndi kulephera kwa kuwala kochepa.

Ngakhale zinthu zachikhalidwe zigamba zimatha kulumikiza ma elekitirodi abwino ndi oyipa kudzera mu waya wagolide wa chip, amalumikizanso mphamvu ya kutentha yopangidwa ndi chip ku pini ya siliva kudzera pa waya wagolide. Kutentha ndi magetsi zimayendetsedwa ndi ndalama. Kutalika kwa nthawi yayitali ya kutentha kumakhudza mwachindunji moyo wa machubu a fulorosenti ya LED.

3. kutentha kutentha

Kuyambitsa ndikugwiritsa ntchito kutentha kwa ma infrared radiation pamachubu a fulorosenti ndi njira yofunikira yopititsira patsogolo moyo wautumiki wamachubu a fulorosenti. Poganizira za kutentha kwa kutentha, timasiyanitsa kutentha kwa mikanda ya nyali ya kuwala kwa LED kuchokera ku magetsi, kuti titsimikizire kuti kutentha kuli koyenera.

Pali njira zitatu zoyendetsera kutentha: convection, conduction ndi radiation. M'malo otsekedwa, ma convection ndi conduction sangathe kuzindikirika, ndipo kutentha kumatulutsa kudzera mu radiation, yomwe ndi cholinga cha machubu a fulorosenti. Zotsatirazi ndizomwe zimayesedwa zamachubu a fulorosenti a LED omwe tidapanga. Kutentha komwe kumayezedwa kunja kwa cholumikizira cha pini yasiliva ya LED ndi madigiri 58 okha.
