Zingwe zowunikira za LED zayamba kutuluka pang'onopang'ono m'makampani okongoletsera chifukwa cha kupepuka kwawo, kupulumutsa mphamvu, kufewa, moyo wautali, komanso chitetezo.Ndiye nditani ngati nyali ya LED siyiyatsa?Otsatirawa LED Mzere wopanga Nanjiguang mwachidule limafotokoza njira kukonza n'kupanga LED.
1. Kuwonongeka kwakukulu kwa kutentha
Kukana kwa kutentha kwa LED sikuli bwino.Choncho, ngati kutentha kwa kuwotcherera ndi nthawi yowotcherera ya LED sikuyendetsedwa bwino panthawi yopanga ndi kukonza, chipangizo cha LED chidzawonongeka chifukwa cha kutentha kwakukulu kapena kutentha kosalekeza, zomwe zidzachititsa kuti mzere wa LED uwonongeke.Chitani imfa.
Yankho: chitani ntchito yabwino pakuwongolera kutentha kwa reflow soldering ndi soldering iron, gwiritsani ntchito munthu wapadera yemwe ali ndi udindo, komanso kasamalidwe ka fayilo yapadera;chitsulo chosungunula chimagwiritsa ntchito chitsulo chowongolera kutentha kuti chiteteze bwino chitsulo chowotcha kuti chiwotche chipangizo cha LED pa kutentha kwakukulu.Tikumbukenso kuti soldering chitsulo sangathe kukhala pa pin LED kwa masekondi 10.Kupanda kutero ndikosavuta kwambiri kuwotcha chipangizo cha LED.
Chachiwiri, magetsi osasunthika amayaka
Chifukwa LED ndi electrostatic tcheru chigawo chimodzi, ngati electrostatic chitetezo si bwino pa ndondomeko kupanga, Chip LED adzawotchedwa chifukwa cha magetsi malo amodzi, amene adzachititsa imfa yabodza ya Mzere wa LED.
Yankho: Limbikitsani chitetezo chamagetsi, makamaka chitsulo chosungunuka chiyenera kugwiritsa ntchito chitsulo chotsutsa-malo.Ogwira ntchito onse omwe amakumana ndi ma LED ayenera kuvala magolovesi odana ndi static ndi mphete za electrostatic malinga ndi malamulo, ndipo zida ndi zida ziyenera kukhala zokhazikika.
3. Chinyezi chimaphulika pansi pa kutentha kwakukulu
Ngati phukusi la LED likuwonekera kwa mpweya kwa nthawi yayitali, limatenga chinyezi.Ngati sichikuwonongeka musanagwiritse ntchito, chimapangitsa kuti chinyezi cha phukusi la LED chiwonjezeke chifukwa cha kutentha kwambiri komanso nthawi yayitali panthawi yokonzanso.Phukusi la LED likuphulika, zomwe zimapangitsa kuti chipangizo cha LED chitenthe kwambiri ndikuchiwononga.
Yankho: Malo osungiramo magetsi a LED ayenera kukhala kutentha ndi chinyezi nthawi zonse.LED yosagwiritsidwa ntchito iyenera kuphikidwa mu uvuni pafupifupi 80 ° kwa maola 6 ~ 8 kuti iwononge chinyezi musanagwiritse ntchito, kuonetsetsa kuti LED yogwiritsidwa ntchito sidzakhala ndi vuto lililonse la kuyamwa kwa chinyezi.
4. dera lalifupi
Mizere yambiri ya LED imatulutsa bwino chifukwa zikhomo za LED ndi zazifupi.Ngakhale nyali za LED zitasinthidwa, zidzasinthanso pang'onopang'ono akapatsidwanso mphamvu, zomwe zidzawotcha tchipisi ta LED.
Yankho: Pezani chomwe chimayambitsa kuwonongeka mu nthawi musanakonze, musalowe m'malo mwa LED mopupuluma, kukonzanso kapena kusintha mwachindunji mzere wonse wa LED mutapeza chifukwa cha dera lalifupi.
