Na farko, yana da mahimmanci don samun fahimtar asali na na'urar hawan dutse (SMD) LEDs. Babu shakka sune LEDs mafi yawan amfani da su a halin yanzu. Saboda juzu'in su, kwakwalwan kwamfuta na LED suna da ƙarfi sosai ga allunan kewayawa kuma ana amfani da su ko da a cikin fitilun sanarwar wayar hannu. Ɗaya daga cikin fitattun fasalulluka na kwakwalwan SMD LED kwakwalwan kwamfuta shine adadin haɗi da diodes.
A guntuwar LED ta SMD, ana iya samun haɗin kai sama da biyu. Har zuwa diode uku tare da da'irori masu zaman kansu ana iya samun su akan guntu ɗaya. Kowane da'ira yana da anode da cathode, yana haifar da haɗin 2, 4, ko 6 akan guntu.
Bambance-bambance tsakanin COB LEDs da SMD LEDs
A kan guntu LED ɗin SMD guda ɗaya, ana iya samun diodes har guda uku, kowanne yana da nasa kewaye. Kowane da'ira a cikin irin wannan guntu yana da cathode da anode, wanda ke haifar da haɗin 2, 4, ko 6. COB kwakwalwan kwamfuta yawanci suna da diode tara ko fiye. Bugu da ƙari, kwakwalwan kwamfuta na COB suna da haɗin haɗin gwiwa biyu da da'ira ɗaya ko da kuwa yawan diodes. Saboda wannan ƙirar kewayawa mai sauƙi, hasken wuta na COB LED yana da kamannin panel, yayin da SMD LED fitilu yayi kama da rukuni na ƙananan fitilu.
Ja, kore, da shuɗi diodes na iya kasancewa akan guntu LED na SMD. Ta hanyar bambanta matakan fitarwa na diodes uku, zaku iya samar da kowane launi. A kan fitilar COB LED, duk da haka, akwai lambobi biyu kawai da da'ira. Ba zai yiwu a yi fitila mai canza launi ko kwan fitila tare da su ba. Ana buƙatar daidaitawar tashoshi da yawa don samun tasirin canza launi. Saboda haka, COB LED fitilu suna aiki da kyau a aikace-aikacen da ke buƙatar launi ɗaya maimakon launuka masu yawa.
Matsakaicin haske na kwakwalwan SMD sanannen sananne shine 50 zuwa 100 lumens kowace watt. COB sananne ne don ingantaccen ingantaccen thermal da lumen per watt rabo. Idan guntu COB yana da aƙalla lumens 80 a kowace watt, zai iya fitar da ƙarin lumen tare da ƙarancin wutar lantarki. Ana iya amfani da shi a cikin nau'ikan kwararan fitila da na'urori daban-daban, kamar filasha ta wayar hannu ko kyamarori masu nuni da harbi.
Baya ga wannan, SMD LED kwakwalwan kwamfuta suna buƙatar ƙaramin tushen makamashi na waje, yayin da kwakwalwan COB LED kwakwalwan kwamfuta suna buƙatar babban tushen makamashi na waje.
