Chekutanga, zvakakosha kuva neruzivo rwekutanga rwema LED eSurface mount device (SMD). Hapana mubvunzo kuti ndiwo ma LED anonyanya kushandiswa pari zvino. Nekuda kwekushanda kwawo kwakasiyana-siyana, ma LED chips akabatanidzwa zvakasimba kuma circuit board akadhindwa uye anoshandiswa zvakanyanya kunyangwe mumagetsi ekuzivisa mafoni. Chimwe chezvinhu zvinonyanya kuzivikanwa zvema LED chips eSMD inhamba yekubatanidza uye ma diode.
Pachip yeSMD LED, panogona kuva nekubatanidza kunodarika kaviri. Madiodhi anosvika matatu ane macircuit akazvimiririra anogona kuwanikwa pachip imwe chete. Chip imwe neimwe ine anode necathode, zvichikonzera kubatana kuviri, 4, kana 6 pachip.
Kusiyana pakati peCOB LEDs neSMD LEDs
Pachip imwe chete yeSMD LED, panogona kuva nemadiode anosvika matatu, imwe neimwe iine circuit yayo. Dunhu rega rega riri muchip yakadaro rine cathode neanode, zvichikonzera kubatana kwe2, 4, kana 6. Machip eCOB anowanzova nemadiode mapfumbamwe kana kupfuura. Pamusoro pezvo, machip eCOB ane kubatana kweviri nedunhu rimwe chete zvisinei nehuwandu hwemadiode. Nekuda kwekugadzirwa kwedunhu iri nyore, mwenje yeCOB LED ine chitarisiko chakafanana nepaneru, nepo mwenje yeSMD LED ichitaridzika seboka remwenje midiki.
Madhiodhi matsvuku, egirini, uye ebhuruu anogona kuvapo paSMD LED chip. Nekusiyanisa mazinga ekubudisa emadiodhi matatu, unogona kugadzira chero ruvara. Zvisinei, parambi reCOB LED, pane maviri chete anobatana uye circuit. Hazvigoneki kugadzira rambi rinochinja ruvara kana bulb nazvo. Kugadziriswa kwematanho akawanda kunodiwa kuti uwane mhedzisiro inochinja ruvara. Naizvozvo, marambi eCOB LED anoshanda zvakanaka mumashandisirwo anoda ruvara rumwe chete pane mavara akawanda.
Kupenya kwemachipisi eSMD kunozivikanwa se50 kusvika 100 lumens pa watt. COB inozivikanwa nekushanda kwayo zvakanyanya kwekupisa uye chiyero che lumen pa watt. Kana chipisi cheCOB chine kanenge 80 lumens pa watt, chinogona kuburitsa malumens akawanda nemagetsi mashoma. Chinogona kushandiswa mumhando dzakasiyana dzemabharubhu nemidziyo, senge flash yefoni kana makamera ekunongedza uye kupfura.
Pamusoro peizvi, machipisi eSMD LED anoda simba diki rekunze, nepo machipisi eCOB LED achida simba guru rekunze.
