Mwenje wemumugwagwa we LED usati watumirwa, unoitwa ongororo dzakasiyana-siyana. Saka ndezvipi zvigadzirwa zvichaongororwa? Usazvidya moyo, chinyorwa chino chichakuudza zvakadzama. Kazhinji,Zvigadziko zvemwenje zve LED zvemugwagwaTichaongorora zvinhu zvishanu zvinotevera tisati tasvika pakuongorora:
Chitupa chemwenje chakabatana
Chinhu chekutanga ndechekutarisa kana chitupa chemwenje chakakodzera.
II Kukurumidza kuziva hunhu hwemwenje yemugwagwa ye LED
Chigadziko chemwenje che LED chinowanzo gadzirwa nechiedza, simba remagetsi uye radiator. Hunhu hwezvinhu zvinoshandiswa uye maitiro anoshandiswa zvinokanganisa zvakanangamutengo wemwenje yemugwagwaKuongorora kunotanga kubva pazvinhu zviri mukati, kuongorora nekukurumidza zvinhu zvakagadziriswa uye maitiro emwenje ye LED kuitira kuziva mhando yemwenje ye LED.
1. Kuedzwa kwakakwana kwekushanda kwemagetsi e LED
Kuedza kushanda kwemagetsi emagetsi (photoelectric performance test) inzira yakakosha yekuongorora nekuratidza mhando yemwenje ye LED, kutsvaga kana paine mamiriro ezvinhu enhema.
2. Kuongororwa kwemhando yepamusoro kwechiedza chepakati chemwenje dze LED
Kuwanikwa kwezviri mukati mechiedza che LED uye mwenje we LED:
(1) Kuongororwa kwemaitiro e lenzi, rudzi rweglue rinovharwa, risina tsvina, mabhurumu, kuongororwa kwekusimba kwemhepo.
(2) Kuongororwa kwemaitiro ekuputira phosphor coating, saizi yephosphor particles, kugoverwa kwehukuru hweparticles, kuumbwa, kana paine agglomeration uye settlement.
(3) Kuongororwa kwemaitiro echip, kuyerwa kwechimiro chechip graphics microstructure, kutsvaga zvikanganiso, kuzivikanwa kwekusvibiswa kwechip, kana paine kubuda kwemagetsi kana kutyoka.
(4) Kuongorora maitiro ekubatanidza lead bonding, kutarisa kwepakutanga uye kwechipiri kwewelding morphology, kuyerwa kwehurefu hwe arc, kuyerwa kwedhayamita, kuzivikanwa kwehuwandu hwelead.
(5) Maitiro ekristaro yakasimba, kuongororwa kwemaitiro ekristaro yakasimba, kana paine nzvimbo isina jira rakasimba, kana paine kupatsanurwa, kuumbwa kwejira rakasimba, ukobvu hwejira rakasimba.
(6) Kuongorora maitiro ekuputira stent, kuumbwa kwestent, kuumbwa kwecoating, ukobvu hwekuputira, kusimba kwemhepo yestent
3. Kuongororwa kwekushanda kwekupisa kwechiedza che LED
Semwenje mutsva unochengetedza simba, mwenje wemugwagwa we LED unongoshandura 30-40% yesimba remagetsi kuita chiedza uye mamwe ese kuita simba rekupisa panguva yekuvhenekesa. Uye hupenyu uye mhando yemwenje ye LED zvine hukama zvakanyanya nekupisa. Tembiricha yemwenje, tembiricha yeganda,kupisatembiricha ichave yakabatana nekufanana kwemwenje ye LED, mhando uye hupenyu hwebasa.
Kuzivikanwa kwekupisa kwemwenje dze LED kunosanganisira zvinhu zvitatu zvinotevera:
(1) Kuongororwa kwekugadzirwa kwemwenje ye LED inoparadza kupisa;
(2) Kana tembiricha yechinhu chimwe nechimwe yakanyanya kukwira mushure mekunge chiedza chasvika pakudziya kwakaringana;
(3) Kuona zvinhu zvinopisa zve LED. Kana ukasarudza kupisa kwakanyanya, kupisa kwakanyanya, uye kupisa kwakanyanya.
4. Kana mwenje dze LED dziine zvinhu zvinokuvadza kunobva chiedza
Mwenje we LED unotya sarufa, uye kukundikana kwawo kunopfuura 50% kunokonzerwa nesulfur bromide chlorination yesilver bead plating layer. Kana sarufa-bromine chlorination reaction ye LED light source ikaitika, nzvimbo inoshanda yechigadzirwa ichave nhema, kuyerera kwechiedza kuchaderera zvishoma nezvishoma, uye tembiricha yemavara ichaonekwa serinoyerera pachena. Mukushandiswa, zviri nyore kuoneka sechiitiko chekubuda kwemagetsi. Mamiriro akakomba ndeekuti sirivha layer inoora zvachose, dhayamita yemhangura inoonekwa, uye bhora regoridhe rinodonha, zvichikonzera chiedza chisina simba. Mwenje we LED une zvinhu zvinopfuura 50, izvo zvinogonawo kunge zvine sarufa, chlorine uye bromine elements. Munzvimbo yakavharwa, tembiricha yepamusoro, zvinhu izvi zve sarufa, chlorine uye bromine zvinogona kuputika kuita magasi uye zvinoparadza masosi e LED light. Mushumo wekuziva kwekubuda kwesarufa kwemwenje ye LED ndiyo kiyi yekuona kuti mwenje we LED unogadzikana.
5. Kuongororwa kwemhando yemagetsi e LED
Basa remagetsi e LED drive nderekushandura magetsi e AC mains kuita magetsi akakodzera LED. Mukusarudza nekugadzira magetsi e LED drive, kuvimbika, kushanda zvakanaka, simba, kutyaira, kudzivirira kukwira kwemvura, kudzivirira kupisa negative feedback nezvimwe zvinhu zvinofanirwa kufungwa nezvazvo. Simba re LED drive remwenje yekunze rinofanira kufunga nezvekushanda kwemvura uye kudzivirira hunyoro, uye ganda rayo rinofanira kunge risingatsvedzi nezuva uye risingachemberi kuti rive nechokwadi chekuti hupenyu hwemagetsi e LED drive hunogona kuenderana nehupenyu hwe LED. Zviri mukati me LED zvinoratidzwa sezviri pazasi:
(1) Zviyero zvemagetsi zvinobuda: voltage, current;
(2) Kana simba rekutyaira richigona kuvimbisa hunhu hwemagetsi anobuda nguva dzose, maitiro ekutyaira emagetsi akachena nguva dzose kana maitiro ekutyaira emagetsi anoramba aripo nguva dzose;
(3) Kana paine dziviriro yakasiyana ye overcurrent, dziviriro ye short circuit uye dziviriro ye open circuit;
(4) kuoneka kwekubuda kwesimba remagetsi: pakushanda nemagetsi, ganda harifanirwe kunge riine chinhu chemagetsi;
(5) Kuona voltage yeRipple: hapana voltage yeripple ndiyo yakanakisa, kana ripple voltage iri shoma, peak iri nani;
(6) Kuongorora kweStrobogram: kana mwenje wemugwagwa we LED uri strobogram mushure mekuvhenekerwa;
(7) Voltage/current inobuda pakatanga: panotanga, simba rinobuda harifanirwe kuoneka voltage/current yakakura;
(8) Kana kuwedzera kwesimba remagetsi kuchienderana nezvinodiwa.
Kuzivikanwa kweChip kubva patsva
Dhatabhesi re LED chip rakaedzwa rine ruzivo rwemachip kubva kuvagadziri vazhinji vemuno nevekunze, data racho rakazara, rakarurama uye rinogadziriswa nekukurumidza. Kuburikidza nekutora nekufananidza, modhi yemachip nemugadziri zvinogona kusimbiswa, izvo zvinobatsira vagadziri vemwenje kuti vavandudze kutonga kwemhando uye kushanda zvakanaka.
Kuongororwa kwechitarisiko uye chimiro chemwenje ye LED
1. Bhuku remabhidhi rinowanzo taura nezvezvinhu zvinoshandiswa pakuvheneka, uye izvi zvichaongororwa zvakadzama. Kuongororwa kwechitarisiko: ruvara rwekuputira rwakafanana, hapana maburi, hapana mitswe, hapana tsvina; Kuputira kunofanira kunamira zvakasimba kune zvinhu zvepasi; Pamusoro pezvikamu zvese zvemwenje ye LED panofanira kunge pakachena, pasina kukwenya, mitswe, kushanduka uye zvimwe zvikanganiso;
2. Kuongororwa kwehukuru: Hukuru hunofanira kusangana nezvinodiwa nedhirowa;
3. Kuongororwa kwekubatanidza: masikuruu ekubatanidza ari pamusoro pechiedza anofanira kusimbiswa, mipendero inofanira kunge isina maburi nemipendero yakapinza, uye zvinobatanidzwa zvinofanira kunge zvakasimba uye zvisina kusununguruka.
Kuyedzwa kweV kusapinda mvura
Sezvishandiso zvemwenje zvinoshanda panze kwemakore ese, uyeMwenje yemugwagwa ye LEDakaiswa munzvimbo yemhepo ine mamita akawanda kusvika anopfuura gumi. Zvakaoma zvikuru kutsiva nekugadzirisa mwenje yemumugwagwa, zvichireva kuti inofanira kushanda zvakanaka kuti isapinda mvura uye isapararire guruva. Saka, giredhi remwenje yemumugwagwa ye LED isingapindi mvura uye isapararire guruva rakakosha zvikuru.
Sezvakaratidzwa pamufananidzo, Zenith Lighting inyanzvi yekugadzira mwenje yemigwagwa yemhando dzakasiyana siyana nezvimwe zvigadzirwa zvine chekuita nayo, kana muine chero mubvunzo kana purojekiti, ndapota musazeza kutibata nesu.
