Paunenge uchitenga mwenje, kazhinji unonzwa vashandi vekutengesa vachiti isu tiri mwenje we LED, kuchengetedzwa kwezvakatipoteredza uye kuponesa simba, ikozvino kwese kwese kunogona zvakare kunzwa nezve led mazwi, kunze kwezviedza zvedu zvinotungamira kuchengetedzwa kwezvakatipoteredza uye kuponesa simba, tinowanzonzwa vanhu vachitaura cob mwenje. , Ndinotenda kuti vanhu vazhinji havana kunzwisisa kwakadzama kwemuguri, saka chii chinonzi cob?Ndeupi musiyano ne LED?
Kutanga kutaura nezve LED, mwenje unotungamira imwenje unoburitsa diode semwenje sosi, chimiro chayo chakakosha ielectroluminescent semiconductor chip, yakasimba-state semiconductor mudziyo, inogona kushandura magetsi kuita chiedza.Imwe mugumo we chip inosungirirwa kune bracket, imwe mugumo i-electrode yakaipa, uye imwe mugumo yakabatanidzwa kune yakanaka electrode yemagetsi emagetsi, kuitira kuti chip yose inoputirwa ne epoxy resin, iyo inodzivirira mukati kati waya. , uye ipapo goko rinoiswa, saka seismic kuita kwemwenje we LED kwakanaka.Led light Angle yakakura, inogona kusvika 120-160 madhigirii, kana ichienzaniswa neyekutanga plug-in pasuru yakakwira kunyatsoshanda, kunaka kwakaringana, yakaderera welding mwero, uremu huremu, vhoriyamu diki uye zvichingodaro.
Mumazuva ekutanga, takaona barbershops, KTV, maresitorendi, theatre uye mamwe marambi akatungamira akaumbwa nenhamba kana mazwi ainyanya kushandiswa mumabhodhi, uye magetsi e LED ainyanya kushandiswa sezviratidzo uye kuratidza LED mabhodhi.Nekubuda kwemavara machena, anoshandiswawo semwenje.
LED inozivikanwa seyechina chizvarwa chekuvhenekera sosi kana girini mwenje sosi, ine simba rekuchengetedza, kuchengetedzwa kwezvakatipoteredza, hupenyu hwakareba, diki diki, yakachengeteka uye yakavimbika maitiro, anoshandiswa zvakanyanya mumhando dzakasiyana dzezviratidzo, kuratidza, kushongedza, backlight, general lighting uye. urban night scene nemimwe minda.Maererano nekushandiswa kwemabasa akasiyana, inogona kugoverwa mukuratidza ruzivo, marambi emigwagwa, marambi emotokari, LCD screen backlight, general lighting shanu zvikamu.
Muchidzidzo, hupenyu hwesevhisi yemwenje ye LED (imwe mwenje emitting diode) kazhinji maawa gumi.Zvisinei, mushure mekuungana mumwenje, nokuti zvimwe zvikamu zvemagetsi zvinewo hupenyu, saka mwenje we LED haugoni kusvika maawa 10 000 ehupenyu hwebasa, kazhinji, inogona kusvika maawa 5 000 chete.
Iyo COB mwenje sosi inoreva kuti iyo chip yakarongedzwa zvakananga pane iyo yese substrate, kureva, N machipi anogarwa nhaka uye akabatanidzwa pamwechete pane substrate yekurongedza.Iyi tekinoroji inobvisa iyo pfungwa yerutsigiro, hapana plating, hapana reflow, hapana chigamba maitiro, saka maitiro anoderedzwa neinenge 1/3, uye mutengo unochengetwawo ne1/3.Inonyanya kushandiswa kugadzirisa dambudziko repasi-simba chip kugadzira yakakwirira-simba LED mwenje, iyo inogona kuparadzira kupisa kupisa kweiyo chip, kunatsiridza kushanda kwechiedza, uye kugadzirisa glare mhedzisiro yemwenje ye LED.COB ine high luminous flux density, kupenya kushoma uye mwenje wakapfava, uye inoburitsa kugovera kwakafanana kwechiedza.Mumashoko akakurumbira, inonyanya kufambira mberi kupfuura magetsi akatungamirirwa, magetsi akawanda ekudzivirira maziso.
Musiyano uripo pakati peCob rambi nemwenje unotungamira ndewekuti mwenje unotungamira unogona kuchengetedza kuchengetedzwa kwezvakatipoteredza, hapana stroboscopic, hapana ultraviolet mwaranzi, uye kushata ndiko kukuvadza kwechiedza chebhuruu.Cob mwenje wakakwira ruvara rwekupa, ruvara rwakareruka padyo nemuvara wechisikigo, hapana stroboscopic, hapana kupenya, hapana magetsi emagetsi, hapana ultraviolet mwaranzi, infrared radiation inogona kudzivirira maziso neganda.Aya maviri ari ma LED, asi nzira yekurongedza yakasiyana, cob kurongedza maitiro uye kushanda kwechiedza zvakanyanya kubatsira, ndiyo ramangwana rekusimudzira maitiro.
