Inokanganisa Kuderera kweMamwenje e LED
Sezvo rudzi rutsva rwechiedza chegirini, marambi e LED anochengetedza simba, ane ushamwari kwezvakatipoteredza uye anogara kwenguva refu, uye anoremekedzwa zvikuru nevatengi. Asi dambudziko rekuora kwe LED nderimwe dambudziko iro marambi e LED anofanira kutarisana nawo. Kuora kwechiedza kusingapindiki kwakakanganisa zvakanyanya kushandiswa kwemarambi e LED.
Parizvino, kuora kwemwenje machena ma LED pamusika inogona kunge iri imwe yenyaya dzekutanga kana uchifamba uchivhenekera vanhuwo zvavo. Chii chinokonzeresa kudzikisira kwemwenje kwema LED? Kazhinji kutaura, pane zvinhu zviviri zvakakosha zvekudzikisa chiedza che LEDs:
I. Matambudziko emhando yezvigadzirwa zve LED:
1. Iyo yakagamuchirwa LED chip haisi muhutano hwakanaka, uye kupenya kunoora nekukurumidza.
2. Pane kukanganisa mukugadzirwa kwekugadzira, uye LED chip heat haigone kutorwa zvakanaka kubva paPini yepini, zvichiita kuti yakanyanya kukwira LED chip tembiricha uye kuwedzera chip attenuation.
II. Mamiriro ekushandisa:
1. Iyo LED inotungamirirwa neanogara aripo, uye mamwe ma LED anotungamirirwa nemagetsi kuti aite kuti LED iparare.
2. Ikozvino dhiraivha yakakura kudarika yakatarwa mamiriro ekutyaira.
Muchokwadi, kune zvikonzero zvakawanda zvekuora kwezvigadzirwa zve LED. Nyaya inonyanya kukosha idambudziko rekupisa. Kunyange zvazvo vagadziri vakawanda vasingatarisi zvakanyanya dambudziko rekupisa kupisa muzvigadzirwa zvechipiri, kushandiswa kwenguva refu kwezvinhu izvi zvechipiri zve LED zvichabhadhara zvakanyanya kuparara kwekupisa kupfuura zviripo. Zvigadzirwa zve LED zvakakwirira. Iko kupisa kwekupokana kweiyo LED chip pachayo, pesvedzero yesirivheri glue, kupisa kwekupisa kweiyo substrate, uye colloid negoridhe waya zvine hukamawo nekudzikisira mwenje.
III. Zvinhu zvitatu zvinokanganisa kunaka kwemarambi e LED
1. Kusarudza kuti ndeapi marudzi emwenje machena e LED
Unhu hwe LED chena chiedza chinhu chakakosha zvikuru. Kupa mimwe mienzaniso, iyo yakafanana crystal 14mil chena mwenje segment chip semumiriri, iyo chena mwenje we LED yakazara neyakajairwa epoxy resin-yakagadzirwa base, chena mwenje glue uye pasuru glue. Kuvhenekera kumwe chete munzvimbo ye30 degree kunoratidza dhata rekudzora kweyero inopenya yekugadzirisa ye70% mushure memaawa chiuru.
Kana ukashandisa Kirasi D yakaderera-kuora glue package, munzvimbo imwechete yekuchembera, kupenya kwayo kupenya pachuru awa ndeye 45%.
Kana ukashandisa Kirasi C yakaderera-yakaora glue package, munzvimbo imwechete yekuchembera, kupenya kwayo kupenya pachuru awa i12%.
Kana ukashandisa Kirasi B yakaderera-yakaora glue package, munzvimbo imwechete yekuchembera, kupenya kwayo kupenya pachuru awa i3%.
Kana ukashandisa Kirasi A yakaderera-inoora glue package, munzvimbo imwechete yekuchembera, kupenya kwayo kupenya pachuru awa i6%.
2. Tichifunga nezvekushanda kwekushisa kwe LEDs chips
Zvinoenderana nedatha yekuchembera yerambi chena ye LED, kana mwenje chena ye LED ichishanda uye tembiricha yaro iri 30 dhigirii, saka tembiricha yebhuraketi kana iyo imwechete LED chena mwenje ichishanda haipfuure 45 madhigirii. Panguva ino, hupenyu hweiyi LED huchave hwakanyanya kunaka.
Kana paine 100 mwenje machena e LED ari kushanda panguva imwe chete, nguva iri pakati pawo ingori 11.4mm, ipapo tembiricha yebhuraketi yakatenderedza mwenje machena e LED inogona kusapfuura madhigirii makumi mana neshanu, asi iwo marambi ari pakati pemurwi wemwenje anogona. kusvika pakupisa kukuru kwe65 degrees. Panguva ino, ichave muedzo wakaoma kune ma LEDs machipisi nekuti iwo ma LED machena marambi akaungana pakati achave neiyo kukurumidza kuora kwechiedza, nepo mwenje yakatenderedza murwi ichave nekuderera kwechiedza.
Sezvatinoziva, LED inotya kupisa. Iyo yakakwira tembiricha, ipfupi yehupenyu hwe LED, nepo ichidzikira tembiricha, iyo yakareba hupenyu hwe LED. Saka tembiricha yakakodzera yekushandisa ye LEDs inofanira kunge iri pakati peminus 5 ne0 madhigirii. Asi izvozvo hazvibviri pakuita.
Naizvozvo, isu tinofanirwa kusimbaradza basa rekupisa mukugadzirwa kwemarambi seyakadzika tembiricha, iyo yakareba hupenyu hwe LED.
3. Tichifunga nezvemagetsi emagetsi e LEDs chips
Zvinoenderana nemhedzisiro yekuyedza, iyo yakaderera yekutyaira ikozvino, idiki kupisa kunoburitsa uye kuderera kupenya. Zvichienderana neongororo, iyo LED solar mwenje wedunhu dhizaini, kutyaira ikozvino kwemarambi eLED anowanzo kungoita 5-10mA, uye kana huwandu hwemalams hunopfuura mazana mashanu kana kupfuura, kutyaira kwazvino kunowanzo chete 10-15mA. Nekudaro, mutyairi parizvino weyakajairwa LED application ingori 15-18mA, vashoma vanhu vanogadzira ikozvino kune anopfuura 20mA.
Mhedzisiro dzekuedza dzinoratidzawo kuti pasi pe14mA mutyairi parizvino, uye chivharo chisingapindire kumhepo, tembiricha yemhepo mukati inosvika 71 madhigirii, zvigadzirwa zvakaderera-kuora, zero light attenuation mumaawa e1000, uye 3% mumaawa 2000, zvinoreva kuti kushandiswa kweiyo yakaderera-yakaora LED mwenje mwenje yasvika pakureba kwayo munzvimbo yakadaro uye ipapo chikuru chiri kukuvadza kwairi kana pamusoro pehukuru hwayo.
Nekuti ndiro yekuchembera haina basa rekubvisa kupisa, saka kupisa kunoitwa neLED painoshanda hakufambiswe kunze, kunyanya zviedzo zvakaratidza pfungwa iyi. Tembiricha yemhepo mukati mendiro yekuchembera yasvika pakupisa kukuru kwe101 degrees, nepo tembiricha yepasi pechivharo pandiro yekuchembera ingori madhigirii makumi mashanu nenhatu, inova mutsauko wemakumi akati wandei emadhigirii. Izvi zvinoratidza kuti chivharo chepurasitiki chakagadzirwa hachina basa rekutonhora rekudziya. Zvisinei, mukugadzirwa kwemarambi akawanda, inofanira kufunga nezvekushanda kwekupisa uye kupisa kupisa.
Naizvozvo, muchidimbu, dhizaini yekushanda magetsi paramita ye LED chips inofanira kunge yakavakirwa pamamiriro chaiwo. Kana kupisa kunoitwa basa remwenje rakanyatsonaka, hazvina basa kana kufambisa ikozvino kwemwenje we LED kwakawedzera zvishoma, nokuti kupisa kunogadzirwa nemwenje we LED kunogona kutumirwa kunze, izvo zvisingakuvadzi mwenje we LED. . Pane zvinopesana, kana iyo yekudziya kutonhora basa remwenje iri sloppy, zviri nani kugadzira dunhu kuti rive diki uye rega kuburitsa kushoma kupisa.
