14 Zofunikira Zamikanda ya Nyali ya LED Pogwiritsa Ntchito Chips za LED

(M'munda wa mikanda ya nyali ya LED, pali zochitika 13 zamakampani.) Ili ndi mpweya waukadaulo ndipo zinthu zamtundu wapamwamba ndizotsimikizika. Mikanda ya nyali ya LED yopangidwa ndi Technology Co., Ltd. gwiritsani ntchito mabwalo okhazikika. Zotsatirazi ndi kupanga mikanda ya nyali ya LED yaukadaulo Co., Ltd. 14 magawo ofunikira: 1. Zabwino zogwirira ntchito pano IF: Zimatanthawuza. Mukamagwiritsa ntchito, muyenera kusankha ngati ili pansipa 0.6 · ngati M. 2. Voltage yogwira ntchito yabwino VF: Magetsi ogwirira ntchito omwe amaperekedwa patebulo la parameter amapezedwa pansi pa kutsogolo kwapano. Nthawi zambiri amayezedwa IF = 20mA. Diode yowunikira ndi mphamvu yogwira ntchito VF pa 1.4 3V. Kutentha kwakunja kukakwera, VF idzachepa. 3. Makhalidwe a V-I: Ubale pakati pa voteji ndi panopo ya diode yotulutsa ndi yapano. Pamene voliyumu yakutsogolo ili yocheperapo mtengo wina (wotchedwa khomo), yapano imakhala yaying'ono kwambiri ndipo siyimatulutsa kuwala. Mphamvu yamagetsi ikadutsa mtengo wina, kutsogoloku kumawonjezeka mofulumira ndi magetsi, kuwala. 4. Mphamvu yowala IV: Kutulutsa kowala kwa diode yotulutsa kuwala nthawi zambiri kumatanthawuza mphamvu yotulutsa kuwala molunjika njira ya mzere (ku chitoliro chowala chowoneka bwino chimatanthawuza m'mbali mwake). Ngati mphamvu ya radiation ndi (1/683) w/sr mbali iyi, yanirani 1 Candra (CD). Chifukwa cha mphamvu yaying'ono ya ma diode otulutsa kuwala kwa ma LED, makandulo (Kandla, MCD) amagwiritsidwa ntchito ngati mayunitsi pakuwala kowala. 5. Ore angle ya LeD: -90 - 90 6. Spectrum semi-width : Imawonetsa chiyero cha mawonekedwe a chitoliro cha kuwala. 7. Theka la mtengo wa 1/2 ndi kawonedwe: 1/2 amatanthauza ngodya yapakati pa mphamvu yotulutsa mphamvu ya theka la mphamvu ya axial ndi ngodya ya kuwala (njira yolowera). 8. Mawonekedwe athunthu: Malinga ndi ngodya ya ngodya yowala ya stereo ya LED, yomwe imatchedwanso ngodya ya ndege. 9. Kawonedwe kawonedwe: Kumatanthawuza kumtunda waukulu wa kuwala kwa LED, malingana ndi momwe amaonera, kugwiritsa ntchito kumasiyananso, kumatchedwanso kuwala kolimba. 10. Theka-woboola pakati: Mlingo pakati pa njira pakati pa 0 ndi kuwala kowala kwambiri/2. Kunena zowona, ngodya yowoneka bwino kwambiri komanso kuchuluka kowala kwambiri/2. Ukadaulo wa ma CD a LED umatsogolera pakuwunikira kopitilira muyeso wa kuwala sikuli mtengo wamphamvu wa 0. Kumayambiriro kwa ngodya yopatuka, yomwe imatanthawuza kupendekera pakati pa kulimba kowala kwambiri ndi kolowera pakati pa njira yochokera ku 0. 11. Pazipita zabwino DC panopa IFM: Pazipita zabwino DC panopa zololedwa kuloledwa. Zoposa mtengo uwu zimatha kuwononga diode. 12. Vuto lalikulu la reverse VRM: Magetsi opitilira muyeso omwe amaloledwa ndi omwe amaloledwa kuwonjezera ndi magetsi owonongeka. Kuposa mtengo uwu, ma diode otulutsa kuwala amatha kusweka ndikuwonongeka. 13. Malo ogwirira ntchito TOPM: Kutentha kwa chilengedwe komwe kumatha kugwira ntchito bwino. Pansi kapena pamwamba kuposa kutentha uku, diode yotulutsa kuwala siigwira ntchito bwino, ndipo mphamvuyo imachepetsedwa kwambiri. 14. Kugwiritsa ntchito mphamvu kovomerezeka PM: Mtengo wokwanira wa kuchuluka kwa voteji yachindunji ya DC ndikudutsa malekezero awiri a LED. Kuposa mtengo uwu, kutentha kwa LED ndi kuwonongeka. Nkhaniyi ikuchokera kwa opanga nyali za LED.
