Pogula magetsi, nthawi zambiri amamva ogulitsa akunena kuti ndife nyali za LED, chitetezo cha chilengedwe ndi kupulumutsa mphamvu, tsopano paliponse tikhoza kumvanso za mawu otsogolera, kuwonjezera pa magetsi athu omwe timawadziwa bwino chitetezo cha chilengedwe ndi kupulumutsa mphamvu, nthawi zambiri timamva anthu akutchula nyali za chisononkho. , Ndikukhulupirira kuti anthu ambiri sadziwa mozama za chisononkho, ndiye kuti chisononkho ndi chiyani?Kodi pali kusiyana kotani ndi LED?
Choyamba kulankhula za LED, nyali yoyendetsedwa ndi kuwala kotulutsa diode monga gwero la kuwala, kapangidwe kake koyambira ndi chipangizo cha electroluminescent semiconductor chip, ndi chipangizo cholimba cha semiconductor, chimatha kusintha magetsi kukhala kuwala.Mbali imodzi ya chip imamangiriridwa ku bulaketi, mbali imodzi ndi electrode yolakwika, ndipo mapeto ena amagwirizanitsidwa ndi electrode yabwino yamagetsi, kotero kuti chip chonse chimatsekedwa ndi epoxy resin, yomwe imateteza waya wapakati pakatikati. , ndiyeno chipolopolocho chimayikidwa, kotero kuti ntchito ya seismic ya nyali ya LED ndi yabwino.Anatsogolera kuwala Angle ndi lalikulu, akhoza kufika madigiri 120-160, poyerekeza ndi pulagi-mu phukusi oyambirira Mwachangu, mwatsatanetsatane bwino, otsika kuwotcherera mlingo, kulemera kuwala, voliyumu yaing'ono ndi zina zotero.
M'masiku oyambirira, tinawona malo ometera, KTV, malo odyera, zisudzo ndi magetsi ena otsogola opangidwa ndi manambala kapena mawu omwe amagwiritsidwa ntchito kwambiri m'zikwangwani, ndipo nyali za LED zinkagwiritsidwa ntchito kwambiri monga zizindikiro ndi ma board a LED.Ndi kutuluka kwa ma LED oyera, amagwiritsidwanso ntchito ngati kuunikira.
LED imadziwika kuti gwero lachinai lounikira kapena gwero la kuwala kobiriwira, ndi kupulumutsa mphamvu, kuteteza chilengedwe, moyo wautali, kukula kochepa, makhalidwe otetezeka komanso odalirika, omwe amagwiritsidwa ntchito kwambiri pazisonyezero zosiyanasiyana, kuwonetsera, zokongoletsera, kuwala kwambuyo, kuunikira kwapadera ndi zochitika za m'tauni usiku ndi madera ena.Malinga ndi ntchito zosiyanasiyana ntchito, zikhoza kugawidwa mu kusonyeza zambiri, magetsi magalimoto, nyali galimoto, LCD chophimba backlight, kuunikira ambiri magulu asanu.
Mwachidziwitso, moyo wautumiki wa magetsi a LED (ma diode otulutsa kuwala kamodzi) nthawi zambiri amakhala maola 10,000.Komabe, mutatha kusonkhanitsa mu nyali, chifukwa zipangizo zina zamagetsi zimakhalanso ndi moyo, kotero nyali ya LED sichitha kufika maola 10,000 a moyo wautumiki, nthawi zambiri, imatha kufika maola 5,000 okha.
Gwero la kuwala kwa COB limatanthawuza kuti chip chimayikidwa mwachindunji pagawo lonse lapansi, ndiye kuti, tchipisi ta N timatengera choloŵa ndikuphatikizidwa pamodzi pagawo lopakira.Tekinolojeyi imathetsa lingaliro la chithandizo, palibe plating, palibe kubwereza, palibe ndondomeko ya chigamba, kotero ndondomekoyi imachepetsedwa ndi pafupifupi 1/3, ndipo mtengo umapulumutsidwanso ndi 1/3.Amagwiritsidwa ntchito kwambiri pothana ndi vuto la magetsi otsika amphamvu kwambiri a chip omwe amatha kutulutsa kutentha kwa chip, kuwongolera kuyatsa bwino, ndikuwongolera kuwunikira kwa nyali za LED.COB ili ndi kachulukidwe kowala kwambiri, kuwala kochepa komanso kuwala kofewa, ndipo imatulutsa kuwala kofanana.M'mawu otchuka, ndi apamwamba kwambiri kuposa magetsi otsogolera, magetsi oteteza maso.
Kusiyana pakati pa nyali ya Cob ndi nyali yotsogozedwa ndikuti nyali yotsogola imatha kupulumutsa chilengedwe, palibe stroboscopic, palibe cheza cha ultraviolet, ndipo choyipa chake ndikuwononga kuwala kwa buluu.Kuwonetsa kowala kwamtundu wa Cob, utoto wopepuka pafupi ndi mtundu wachilengedwe, palibe stroboscopic, palibe kunyezimira, palibe kuwala kwamagetsi, palibe kuwala kwa ultraviolet, kuwala kwa infrared kumatha kuteteza maso ndi khungu.Awiriwa ndi ma LED, koma njira yoyikamo ndi yosiyana, kuyika kwa cob ndi kuwala kwabwino kumakhala kopindulitsa, ndiye chitukuko chamtsogolo.
