Dziko laukadaulo wa LED likukula mwachangu, likupereka zosankha zosiyanasiyana pazogwiritsa ntchito zosiyanasiyana.Mitundu iwiri yodziwika bwino ya ma LED ndi SMD (Surface-Mounted Device) ndi COB (Chip on Board).Matekinoloje onsewa ali ndi mawonekedwe ake apadera, maubwino ake, komanso ntchito zawo.Blog iyi ikufuna kufananiza SMD LED ndi COB LED, kukuthandizani kumvetsetsa zomwe zingakhale zabwinoko pazosowa zanu zenizeni.
Kumvetsetsa ma SMD ndi COB LEDs
SMD LED (Chida Chokwera Pamwamba):
- Kupanga: Ma LED a SMD amayikidwa mwachindunji pamwamba pa bolodi yozungulira.Atha kukhala ndi ma diode angapo pa chip chimodzi, nthawi zambiri amakona anayi kapena mainchesi.
- Zigawo: Ma LED a SMD amatha kuphatikiza ma diode ofiira, obiriwira, ndi abuluu (RGB) mu phukusi limodzi, kulola kusakanikirana kwamitundu ndi mitundu yambiri.
- Mapulogalamu: Amagwiritsidwa ntchito kwambiri pazowonetsera zamagetsi, ma TV, mizere ya LED, ndi njira zowunikira zonse.
COB LED (Chip pa Board):
- Kupanga: Ma LED a COB ali ndi ma diode angapo (nthawi zambiri opitilira asanu ndi anayi) amayikidwa mwachindunji pagawo, ndikupanga gawo limodzi.Izi zimapangitsa kuti pakhale gwero lowundana komanso lofanana.
- Zigawo: Ma diode mu COB LED amayikidwa moyandikana, nthawi zambiri pansi pa zokutira limodzi la phosphor, lomwe limatulutsa kutulutsa kofanana komanso kowala.
- Mapulogalamu: Zoyenera kuwunikira pansi, zowunikira, zowunikira zapamwamba, ndi mapulogalamu ena omwe amafunikira kuyatsa kwambiri.
Kusiyana Kwakukulu Pakati pa SMD ndi COB LEDs
- Kutulutsa Mwachangu ndi Mwachangu
- Chithunzi cha SMD LED: Amapereka kuwala kocheperako mpaka kokwera kwambiri komanso bwino.Itha kugwiritsidwa ntchito pakuwunikira kwanthawi zonse komanso kamvekedwe kake chifukwa cha kusinthasintha kwake popanga mitundu yosiyanasiyana komanso milingo yowala.
- LED COB: Odziwika chifukwa chotulutsa kuwala kwambiri komanso kuchita bwino kwambiri, ma COB LED amapereka kuwala kwakukulu komanso kofanana.Ndiwothandiza makamaka pamapulogalamu omwe amafunikira kuunikira kwamphamvu.
- Kutentha Kutentha
- Chithunzi cha SMD LED: Amatulutsa kutentha kochepa poyerekeza ndi ma COB LED.Kutentha kwa kutentha kumayendetsedwa kudzera mu bolodi la dera ndi matenthedwe otentha, kuwapanga kukhala oyenera kupanga mapangidwe ang'onoang'ono.
- LED COB: Imatulutsa kutentha kwambiri chifukwa cha dongosolo la diode lapamwamba kwambiri.Njira zoyendetsera kutentha bwino, monga zotengera kutentha, ndizofunikira kuti tipewe kutenthedwa komanso kuonetsetsa kuti moyo ukhale wautali.
- Colour Rendering Index (CRI)
- Chithunzi cha SMD LED: Nthawi zambiri imapereka CRI yabwino, yomwe ili yoyenera kugwiritsa ntchito zambiri.Ma LED a High-CRI SMD amapezeka pamapulogalamu omwe amafunikira mawonekedwe olondola amtundu.
- LED COB: Nthawi zambiri imakhala ndi CRI yapamwamba, yomwe imapangitsa kuti ikhale yoyenera pazikhazikiko zomwe kulondola kwamtundu ndikofunikira, monga kuunikira kwamalonda, kujambula, ndi ntchito zamankhwala.
- Kusinthasintha kwapangidwe
- Chithunzi cha SMD LED: Zosunthika kwambiri ndipo zitha kugwiritsidwa ntchito pamasinthidwe osiyanasiyana.Kukula kwake kophatikizika kumapangitsa kuti pakhale mapangidwe apamwamba komanso otsogola mumizere ya LED, zowonetsera, ndi zowunikira zamamangidwe.
- LED COB: Amapereka kusinthasintha kwapangidwe kochepa chifukwa cha kukula kwake kwakukulu ndi kutulutsa kutentha.Komabe, imapambana pamapulogalamu omwe amafunikira gwero lamphamvu komanso lofanana.
- Mtengo
- Chithunzi cha SMD LED: Ndiotsika mtengo kwambiri chifukwa chofala komanso njira zopangira zopangira.Mtengo ukhoza kusiyanasiyana malinga ndi kuchuluka kwa ma diode ndi mtundu wake.
- LED COB: Amakonda kukhala okwera mtengo chifukwa cha kuchuluka kwa ma diode pa chip komanso kufunikira kowongolera kutentha kwapamwamba.Komabe, mtengo wake umalungamitsidwa pakugwiritsa ntchito kuyatsa kwamphamvu kwambiri.
Chabwino n'chiti?
Kusankha pakati pa ma SMD ndi COB LED kutengera zomwe mukufuna kugwiritsa ntchito:
- Sankhani SMD LED ngati mukufuna:
- Kusinthasintha pakupanga ndi kugwiritsa ntchito.
- Kuwala kwapakatikati mpaka kokwera kokwanira bwino.
- Kuchepetsa kutentha kwapang'onopang'ono, koyenera kupanga mapangidwe ang'onoang'ono.
- Njira zotsika mtengo zowunikira wamba komanso kamvekedwe ka mawu.
- Sankhani COB LED ngati mukufuna:
- Kuchuluka kwambiri, kutulutsa kofanana kowala.
- Mapulogalamu omwe amafunikira CRI yapamwamba komanso mawonekedwe olondola amtundu.
- Njira zothetsera kuyatsa kwapamwamba, zowunikira zotsika, ndi zowunikira.
- Gwero lamphamvu komanso losasinthasintha, ngakhale kuti mtengo wake ndi wokwera komanso zofunikira pakuwongolera kutentha.
Mapeto
Ma LED onse a SMD ndi COB ali ndi maubwino ake ndipo ndi oyenera kugwiritsa ntchito zosiyanasiyana.Ma LED a SMD amapereka kusinthasintha, kuchita bwino, komanso kugulidwa, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana.Ma LED a COB amapereka kuwala kowoneka bwino, kofananira komanso kutulutsa bwino kwamitundu, kuwapangitsa kukhala abwino kwambiri pakugwiritsa ntchito kwambiri komanso CRI yapamwamba.Pomvetsetsa mphamvu ndi zofooka za mtundu uliwonse, mukhoza kupanga chisankho chodziwika bwino chomwe chimakwaniritsa zosowa zanu zowunikira.
