Ubwino wa nyali za LED
1. Thupi la nyali ndi laling'ono kwambiri
Nyali ya LED ndi yaying'ono, yabwino kwambiri ya LED chip yomwe imayikidwa mu epoxy yowonekera, kotero ndi yaying'ono kwambiri komanso yopepuka kwambiri.
2. Kugwiritsa ntchito mphamvu zochepa kwambiri
Mphamvu yogwiritsira ntchito chipangizo cha LED ndi yaying'ono, ndipo mphamvu yogwiritsira ntchito imachepetsedwa moyenerera. Chifukwa chake, kugwiritsa ntchito mphamvu kwa nyali ya LED ndikocheperako, ndipo mphamvu yamagetsi yomwe imagwiritsidwa ntchito imachepetsedwa ndi 90% kuposa nyali yowala yowala kwambiri, ndipo imachepetsedwa ndi 70% poyerekeza ndi nyali yopulumutsa mphamvu. .
3. Yolimba ndi yolimba
Chophika cha LED chimakutidwa kwathunthu mu epoxy. Tizigawo tating'ono ta epoxy resin ndizovuta kwambiri kuthyoka, ndipo thupi lonse la nyali lilibe ziwalo zotayirira; mkate wamkati ndi wovuta kwambiri kuthyoka, ndipo pali mphamvu yochepa yotentha yomwe imatha kusungunuka ndi kusungunuka. Poyerekeza ndi mababu wamba, nyali za fulorosenti, izi zimapangitsa ma LED kukhala ovuta kuwonongeka.
4. Nyali ya LED imakhala ndi moyo wautali wautumiki
Pa nthawi yoyenera ndi magetsi, moyo wa nyali ya LED ukhoza kufika maola 100,000, zomwe zikutanthauza kuti moyo wa mankhwala ndi zaka zoposa 10, zomwe zimakhala ndi moyo wautali kuposa mitundu ina ya nyali.
5. Otetezeka komanso otsika magetsi
Nyali ya LED imagwiritsa ntchito magetsi otsika kwambiri a DC. Magetsi operekera ali pakati pa 6 ndi 48V. Mphamvu yamagetsi imasiyanasiyana malinga ndi mankhwala. Imagwiritsa ntchito magetsi a DC omwe ali otetezeka kuposa magetsi okwera kwambiri.
6. Ntchito zosiyanasiyana
Chip chilichonse cha LED ndi 3 ~ 5mm lalikulu kapena kuzungulira, chomwe chili choyenera kwambiri pakupanga mawonekedwe a nyali za LED, zomwe zimapindulitsa pakupanga makina owoneka bwino.
7. Zambiri zokongola
Mtundu wamtundu wa luminaire ndi wosavuta kwambiri. Kuti akwaniritse cholinga cha mtundu, wina ndi kujambula kapena kuphimba pamwamba pa utoto wonyezimira, ndipo winayo ndi kulipiritsa luminaire ndi mpweya wa inert, kotero kuti kulemera kwa mtundu kumakhala kochepa. LED ndi kulamulira kwa digito, chip-emitting chip chikhoza kutulutsa mitundu yosiyanasiyana, kuphatikizapo yofiira, yobiriwira, yabuluu yamitundu itatu, kupyolera mu kayendetsedwe ka kayendetsedwe kake, imatha kulamulira mitundu yosiyanasiyana.
8. Kutentha kwapang'ono
LED ndi gwero lapamwamba lozizira lozizira. Simawunikira kuchuluka kwa kuwala kwa infrared ndi kuwala kwa ultraviolet ngati nyali za incandescent ndi nyali za fulorosenti, ndipo ndi yoyenera kumapulojekiti osiyanasiyana owunikira panja. Nyali za LED sizikhala ndi mphamvu yotentha ya nyali za incandescent ndipo siziphulika chifukwa cha kuwonjezereka kwa kutentha ndi kutsika. Sichidzapangitsa babu kukhala chikasu, sichidzafulumizitsa kukalamba kwa nyali, ndipo sichidzakhala ndi wowonjezera kutentha pa chilengedwe.
9. Kuchepa kwa chilengedwe
Pali zinthu zitatu zoteteza ma LED m'chilengedwe:
Choyamba, palibe ngozi ya zitsulo za mercury. Nyali za LED sizigwiritsa ntchito mercury yowopsa kwambiri ngati nyali za fulorosenti, ndipo palibe zoopsa zapagulu monga ma mercury ion kapena phosphors panthawi yopanga nyali kapena pambuyo pakuwonongeka.
Kachiwiri, utomoni wa epoxy wopangira LED ndi organic polima pawiri, yomwe ili ndi zinthu zabwino zakuthupi ndi zamankhwala pambuyo pochiritsa. Zili ndi mphamvu zomangirira kwambiri zowomba ndi zitsulo, zimakhala zolimba komanso zosinthika, ndipo zimakhala zokhazikika ku mchere ndi alkali ndi zosungunulira zambiri, ndipo siziwonongeka mosavuta. Itha kubwezeretsedwanso ndikugwiritsiridwanso ntchito ngakhale zitawonongeka kapena kukalamba, ndipo sizidzawononga chilengedwe.
Kachitatu, tinthu masanjidwe a nyali LED, kuwala opangidwa zambiri anamwazikana, ndipo kawirikawiri umabala kuipitsa kuwala.
10. Kusunga ndalama zambiri
Poyerekeza ndi nyali za incandescent ndi nyali za fulorosenti, mtengo wogula wa nyali za LED ndi wapamwamba. Komabe, kugwiritsa ntchito mphamvu kwa ma LED kumakhala kotsika kwambiri, ndipo kugwiritsa ntchito nthawi yayitali kumatha kupulumutsa ndalama zambiri zamagetsi, zomwe zingapulumutse ndalama zosinthira nyali, kotero kuti ndalama zonse zogwiritsira ntchito ndizotsika mtengo.
