ziviso

Kusarudzwa pakati peCOB LED PCB neSMD LED PCB kunomiririra sarudzo huru yekugadzira inokanganisa zvakananga mashandiro echigadzirwa, kushanda zvakanaka kwekugadzira, uye mari yese yepurojekiti. Matekinoroji ese ari maviri ane mabasa akasiyana mumashandisirwo emazuva ano e LED, asi magadzirirwo awo anogadzira mhedzisiro dzakasiyana zvakanyanya maererano nekubuda kwechiedza, hunhu hwekupisa, uye zvinodiwa pakugadzira.

COB LED PCB tekinoroji inosanganisa akawanda machipisi e LED zvakananga pane imwe chete substrate, ichigadzira yakatarisana nepamusoro-simba mwenje sosi ine yepamusoro inopenya density. Kusiyana neizvi, SMD LED PCB inoshandisa imwe neimwe yakarongedzwa zvinhu zve LED zvakaiswa pane redunhu bhodhi pamusoro, zvichipa kuchinjika uye modularity kune akasiyana mwenje maapplication.

Chii chinonzi COB LED PCB Technology

COB LED PCB dhizaini inoisa akawanda machipisi e LED zvakananga pane yakadhindwa redunhu bhodhi substrate isina chimwe chikamu chekurongedza. Iyi chip-on-board nzira inobvisa kupisa kwekupisa kwakabatana neyechinyakare LED mapakeji, ichibvumira yakakwira simba density uye kunatsiridza kupisa kupisa kunyatsoshanda.

Hunhu Hunokosha hweCOB LED PCB

Maitiro ekugadzira anosanganisira waya kusungirirwa kana flip-chip yekunamatira isina LED inofa kune PCB substrate, inoteverwa nephosphor coating uye encapsulation. Kubatanidzwa uku kunopa kupenya kwakajeka kwekushanda kubva pa100 kusvika ku150 lumens pawatt zvichienderana nemhando yechip uye kutonga kwekupisa.

COB LED PCB tekinoroji inokunda mumashandisirwo anoda kupenya kwakasimba, kwakafanana munzvimbo dzakatsanangurwa. Iyo yakasimba yakarongedzerwa chip gadziriso inoburitsa yakatsetseka mwenje kugovera pasina inooneka mapoinzi masosi akajairika mune discrete LED arrays.

Chii chinonzi SMD LED PCB Technology

SMD LED PCB inoshandisa tekinoroji yepamusoro-soro kuisa pre-yakaputirwa ma LED zvikamu pabhodhi redunhu. Imwe neimwe SMD LED ine yayo encapsulation, phosphor coating, uye optical lens mukati meakamisikidzwa mapakeji mafomati akadai se2835, 3030, kana 5050 masisitimu.

Hunhu Hunokosha hweSMD LED PCB

Iyo modular chimiro cheSMD LED PCB inopa yakakosha dhizaini kuchinjika, ichibvumira mainjiniya kugadzirisa huwandu hweLED, nzvimbo, uye hurongwa hwekusangana nezvinodiwa zvekuvhenekera. Yakajairwa chikamu saizi inogonesa otomatiki yekutora-uye-nzvimbo kusangana ine yakakwira throughput uye yakaderera kuremara mitengo.

SMD LED PCB inoshandisa zvikumbiro uko discrete control, yakaderera simba density, kana mutengo-isinganzwisisike kugadzira inotyaira dhizaini sarudzo. Kuitwa kwakajairika kunosanganisira backlighting masisitimu, marambi echiratidzo, mwenje wekushongedza, uye maratidziro emagetsi evatengi.

Kuenzanisa Kwekuita: COB LED PCB vs SMD LED PCB

Kupenya uye Kubudirira Kwekupenya

COB LED PCB inoburitsa kupenya kwakanyanya kuburitsa pachikamu chimwe chete kana ichienzaniswa neSMD LED PCB nekuda kweyakaomeswa chip kuronga. Iyo yakajairika COB module inowana inopenya flux kukosha kwe5,000 kusvika 20,000 lumens kubva kune imwechete module, ichiita kuti ifarirwe kune yakakwira-kubuda maapplication.

SMD LED PCB inopa kupenya kwakakwana kune mwero kuvhenekera mazinga, kazhinji kuburitsa 20 kusvika 200 lumens pane yega yega chikamu che LED. Ichiri yakaderera pane COB tekinoroji mumashoko akakwana, SMD LED PCB inopa mabhenefiti anoshanda mumashandisirwo anoda akagoverwa magetsi masosi kana anogadzirika kudzora.

Thermal Management muCOB LED PCB uye SMD LED PCB

Thermal performance inomiririra yakakosha mutsauko pakati peaya matekinoroji maviri:

• COB LED PCB yekupisa zvinodiwa -Inotarisa kuparara kwesimba mudiki tsoka, zvichidikanwa aluminium substrates, inoshanda kutonhora, kana yakakura heatsink kubatanidzwa kuchengetedza junction tembiricha iri pasi pe85 ° C.
• SMD LED PCB yekupisa zvakanakira -Inogovera kupisa kune akawanda ega ega zvikamu, kuderedza kupisa kwemafuta pane imwe nzvimbo pabhodhi redunhu.
• Kusarudzwa kwe substrate - Yakajairwa FR4 substrates kazhinji inokwana kune yakaderera-simba SMD LED PCB application, nepo COB inoda simbi-musimboti PCBs kana ceramic substrates.
• Kutonhora kuoma -Kudzikira kwesimba remagetsi pane chimwe chikamu cheSMD chinorerutsa kuita kutonhora kwekuita zvichienzaniswa neyakaomeswa COB magadzirirwo.

Saizi uye Fomu Factor

Iyo compact chimiro cheCOB LED PCB inogonesa kupenya kwepamusoro munzvimbo diki, zvichiita kuti zvive zvakanakira maapplication ane zvakaomesesa dimensional zvipingaidzo. Imwe COB module inogona kutsiva akawanda SMD LEDs uku ichidzikisa yakazara gungano ukobvu.

SMD LED PCB inopa kuchinjika kwepamusoro kune tsika yekuvhenekesa mapatani, maumbirwo, uye akagoverwa arrays. Kuwanikwa kweakasiyana mapakeji saizi inobvumira vagadziri kukwidziridza kuiswa kwe LED kune chaiyo yekuvhenekera mapatani kana kukwana mukati mekuoma PCB geometries.

Mutengo Ongororo: COB LED PCB vs SMD LED PCB

Manufacturing Cost Factors

SMD LED PCB inowanzopa yakaderera mutengo wegungano weyakaderera-kusvika-yepakati vhoriyamu kugadzirwa, inosimudzira yakamisikidzwa zvikamu, otomatiki yekuisa michina, uye yakapfava yekugovera cheni zvinhu. Mitengo yezvikamu inobatsira kubva pakugadzirwa kwepamusoro-vhoriyamu uye akawanda evashambadziri sarudzo.

COB LED PCB inosanganisira yakakwira yekutanga maturusi mutengo uye inoda nyanzvi yekubatanidza michina, chaiyo phosphor application, uye yakasimba yemhando yekudzora panguva yekunamatira chip. Nekudaro, kuderedzwa kwechikamu kuverengera uye kurerutswa optical dhizaini inogona kumisa zvinhu izvi mune yakakwirira-vhoriyamu mamiriro.

Zvose Zvikwereti zveMugove

Paunenge uchiongorora mutengo-kushanda, vagadziri vanofanirwa kufunga nezvese mutengo wehurongwa:

• Thermal management hardware - COB inoda mamwe akasimba ekutonhodza mhinduro, ichiwedzera kumitengo yehurongwa.
• Optical components - COB yakasanganiswa dhizaini inogona kuderedza chechipiri optics zvinodiwa.
• Basa regungano -Zvishoma zvikamu mumagadzirirwo eCOB zvinogona kuderedza nguva yegungano uye kuoma.
• Mutengo-per-lumen kunyatsoshanda - COB LED PCB inogona kuunza kukosha kuri nani mumashandisirwo epamusoro-kubuda kunyangwe mutengo wemodule wakakwira.

Kuvimbika uye Upenyu hweCOB LED PCB uye SMD LED PCB

COB LED PCB Hupenyu

COB LED PCB hupenyu hurefu hunobva pa30,000 kusvika ku50,000 maawa kana yakanyatsogadzirwa tembiricha yekudziya inochengetedza tembiricha iri pasi pe85°C. Iyo yakananga chip yekunamatira inobvisa kukundikana modhi ine chekuita nekushatisa kwepakeji ye LED asi inoisa simbiso huru pane substrate zvinhu kugadzikana uye waya bond kutendeseka.

SMD LED PCB Hupenyu

Kuvimbika kweSMD LED PCB kunoenderana nemhando yechinhu chega uye kushushikana kwekupisa panguva yekushanda. Yakajairwa LED mapakeji inopa yakayerwa hupenyu hwemaawa makumi mashanu kana kupfuura kana ichishandiswa mukati mezvirevo. Iyo yakagoverwa yekupisa mbiri uye yakaderera simba pachikamu che LED kazhinji inokonzeresa kuderera kwemazinga.

Matekinoroji ese ari maviri anoburitsa kuvimbika kwakanyanya kana akagadzirwa neakakodzera margin emafuta, zvemhando yepamusoro, uye akasimba ekugadzira maitiro.

Mirayiridzo Yekusarudza Kwekushandisa

Nguva Yekusarudza COB LED PCB

COB LED PCB inoshandisa zvikumbiro zvinoda kupenya kwakanyanya kubuda, kuvhenekera kweyunifomu, uye compact fomu zvinhu. Mwenje wemumugwagwa, marambi ekutengesa, marambi emota, uye marambi emota anobatsirwa kubva kune yakakwira inopenya density uye yakanakisa ruvara kufanana.

Tekinoroji iyi inokodzerawo mashandisirwo ayo kwatove nezvivakwa zvekutarisira kupisa kana uko mutengo wepamusoro wemhinduro dzakasimba dzekutonhodza unoenderana nenzvimbo yezvigadzirwa. Mwenje wekurapa , michina yehunyanzvi yekutora mifananidzo, uye mwenje wehunyanzvi hwemaindasitiri unomiririra zvikamu izvo mashandiro eCOB LED PCB anoruramisa mari.
