I-SMD LED vs. COB LED - Yikuphi Okungcono?

Ukuqonda ama-SMD nama-COB LED

I-SMD LED (Idivayisi Ebekwe Phansi):

• Idizayini: Ama-LED e-SMD afakwe ngqo phezu kwebhodi lesekethe.Angaba nama-diode amaningi ku-chip eyodwa, ngokuvamile abe umumo ongunxande noma oyisikwele.
• Izingxenye: Ama-LED e-SMD angafaka ama-diode abomvu, aluhlaza, naluhlaza okwesibhakabhaka (RGB) kuphakheji eyodwa, okuvumela ukuxutshwa kwemibala kanye nohlu olubanzi lwemibala.
• Izinhlelo zokusebenza: Isetshenziswa kakhulu ekubonisweni kwe-elekthronikhi, omabonakude, imichilo ye-LED, nezixazululo zokukhanyisa ezijwayelekile.

I-COB LED (Chip on Board):

• Idizayini: Ama-COB LED anama-diode amaningi (ngokuvamile angaphezu kwesishiyagalolunye) afakwe ngokuqondile ku-substrate, edala imojula eyodwa.Lokhu kubangela umthombo wokukhanya ominyene, ofanayo.
• Izingxenye: Ama-diode ku-COB LED abekwe eduze ndawonye, ​​ngokuvamile ngaphansi kwe-phosphor coating eyodwa, ekhiqiza ukuphuma kokukhanya okungaguquki nokugqamile.
• Izinhlelo zokusebenza: Ilungele amalambu aphansi, ama-floodlight, ukukhanya kwe-high-bay, nezinye izinhlelo zokusebenza ezidinga ukukhanya okunamandla kakhulu.

Umehluko Obalulekile Phakathi kwe-SMD ne-COB LEDs

1. Okuphumayo Okukhanyayo nokusebenza kahle
   • I-SMD LED: Inikeza ukukhanya okumaphakathi kuya kokuphezulu ngokusebenza kahle okuhle.Ingasetshenziselwa kokubili ukukhanya okuvamile kanye nokugqama ngenxa yokuguquguquka kwayo ekukhiqizeni imibala ehlukahlukene namaleveli okukhanya.
   • I-COB LED: Eyaziwa ngokukhipha ukukhanya okuphezulu nokusebenza kahle kakhulu, ama-COB LED ahlinzeka ngokukhanya okunamandla nokufana okufanayo.Asebenza kahle kakhulu ezinhlelweni ezidinga ukukhanya okunamandla.
2. Ukushisa Ukushisa
   • I-SMD LED: Ikhiqiza ukushisa okuncane uma kuqhathaniswa nama-COB LED.Ukukhishwa kokushisa kulawulwa ngebhodi lesifunda kanye namasinki okushisa, okubenza bafaneleke imiklamo ehlangene.
   • I-COB LED: Ikhiqiza ukushisa okwengeziwe ngenxa yokuhlelwa kwe-high-density diode.Amasistimu okulawula ukushisa asebenzayo, njengamasinki okushisa, ayadingeka ukuze kuvinjelwe ukushisa nokuqinisekisa ukuphila isikhathi eside.
3. Inkomba Yokunikeza Umbala (CRI)
   • I-SMD LED: Ngokuvamile inikeza i-CRI enhle, elungele izinhlelo zokusebenza eziningi.Ama-LED ama-SMD aphezulu e-CRI ayatholakala kuzinhlelo zokusebenza ezidinga ukumelwa okunembile kombala.
   • I-COB LED: Ivamise ukuba ne-CRI ephakeme, okuyenza ifaneleke kuzilungiselelo lapho ukunemba kombala kubaluleke kakhulu, njengokukhanya okuthengiswayo, ukuthwebula izithombe, nezinhlelo zokusebenza zezokwelapha.
4. Ukuvumelana nezimo
   • I-SMD LED: Iguquguquka kakhulu futhi ingasetshenziswa ekucushweni okuhlukahlukene.Usayizi wayo ohlangene uvumela imiklamo yokudala neyinkimbinkimbi emigqeni ye-LED, izibonisi, nokukhanyisa kwezakhiwo.
   • I-COB LED: Inikeza ukuguquguquka kwedizayini okuncane ngenxa yobukhulu bayo obukhulu kanye nokukhipha ukushisa.Nokho, iyaphumelela ezinhlelweni ezidinga umthombo wokukhanya onamandla nofanayo.
5. Izindleko
   • I-SMD LED: Ngokuvamile iyathengeka ngenxa yokusetshenziswa kwayo okusabalele kanye nezinqubo zokukhiqiza ezisunguliwe.Izindleko zingahluka ngokuya ngenani lama-diode nekhwalithi.
   • I-COB LED: Ivame ukubiza kakhulu ngenxa yenani eliphezulu lama-diode nge-chip ngayinye kanye nesidingo sokuphathwa kokushisa okuthuthukisiwe.Kodwa-ke, izindleko ziyafaneleka ezinhlelweni zokukhanyisa eziphakeme kakhulu.

Ikuphi Okungcono?

Ukukhetha phakathi kwama-SMD nama-COB LED kuncike ezidingweni ezithile zohlelo lwakho lokusebenza:

• Khetha i-SMD LED uma uyidinga:
  • Ukuhlukahluka ekuklanyeni nasekusebenziseni.
  • Ukukhipha ukukhanya okumaphakathi kuya kokuphezulu ngokusebenza kahle okuhle.
  • Ukukhiqiza ukushisa okuphansi, okulungele imiklamo ehlangene.
  • Izixazululo ezingabizi kakhulu zokukhanyisa okuvamile kanye ne-accent.
• Khetha i-COB LED uma uyidinga:
  • Ukuqina okuphezulu, ukuphuma kokukhanya okufanayo.
  • Izinhlelo zokusebenza ezidinga i-CRI ephezulu nokumelwa kombala okunembile.
  • Izixazululo ezisebenzayo zokukhanyisa kwe-high-bay, ukukhanya okuphansi, nama-floodlights.
  • Umthombo wokukhanya onamandla futhi ongaguquguquki, naphezu kwezindleko eziphezulu nezidingo zokuphatha ukushisa.

Isiphetho

Womabili ama-SMD nama-COB LED anezinzuzo zawo ezihlukile futhi afanele izinhlelo zokusebenza ezahlukene.Ama-LED ama-SMD anikezela ngokuguquguquka, ukusebenza kahle, kanye nokufinyeleleka, okuwenza alungele ukusetshenziswa okubanzi.Ama-COB LED ahlinzeka ngokukhanya okuqinile, okufanayo kanye nokunikezwa kombala okuhle kakhulu, okuwenza afanelekele izinhlelo zokusebenza eziphakeme kakhulu neziphezulu ze-CRI.Ngokuqonda amandla nemikhawulo yohlobo ngalunye, ungenza isinqumo esinolwazi esihlangabezana kangcono nezidingo zakho zokukhanyisa.
