1. Kugwiritsa Ntchito Mphamvu Moyenera Kwambiri ndi Kuwongolera Kuwala
Mikanda ya SMD imakhala ndi ma chip payokha, zomwe zimathandiza kuti kuwala kutuluke bwino. Mkanda uliwonse ukhoza kusinthidwa pawokha kuti ukhale wowala komanso kutentha kwa mtundu, zomwe zimathandiza kuti kuwala kugawidwe bwino m'makoma. Kapangidwe kameneka kamachepetsa zinyalala zowunikira ndipo kamawonjezera mphamvu yowala—Makampani a SMD nthawi zambiri amakhala ndi mphamvu yochuluka ndi 10-15% kuposa mitundu ya COB. Mwachitsanzo, nyali ya khoma ya 8W SMD imatha kupanga lumen yofanana ndi nyali ya COB ya 15W, zomwe zimachepetsa mtengo wamagetsi kwa ogwiritsa ntchito.
2. Kukonza Kotsika Mtengo ndi Kutalika kwa Nthawi
Mosiyana ndi mikanda ya COB, pomwe chip imodzi yolakwika ingapangitse gulu lonse kukhala lopanda ntchito, mikanda ya SMD imatha kusinthidwa payekhapayekha. Modularity iyi imachepetsa kwambiri ndalama zokonzera: ngati mkanda umodzi walephera, chipangizo cholakwika chokhacho chimafunika kusinthidwa, m'malo mwa gawo lonse la magetsi. Kuphatikiza apo, mikanda ya SMD imakhala ndi kutentha kochepa chifukwa cha malo ake olumikizirana, zomwe zimawonjezera moyo wawo mpaka maola 20,000 poyerekeza ndi kuchuluka kwa kutentha kwa COB, komwe nthawi zambiri kumabweretsa kukalamba msanga.
3. Kutaya Kutentha Kwambiri
Kulekanitsidwa kwapakati pa mikanda ya SMD kumathandizira kuti mpweya uziyenda bwino mozungulira chip chilichonse, kuchepetsa kusokonezeka kwa kutentha. Kutaya kutentha kogwira mtima kumeneku kumasunga magwiridwe antchito okhazikika pakapita nthawi, kuteteza kuwonongeka kwa kuwala komwe kumachitika chifukwa cha kutentha kwambiri - vuto lofala m'makina a COB pomwe kutentha kwambiri kumatha kuchepetsa kuwala ndi 30% mkati mwa zaka ziwiri. Chifukwa chake, nyali za SMD pakhoma zimakhalabe zowala nthawi yayitali.
4. Ubwino Wachilengedwe Ndi Wosavuta Kugwiritsa Ntchito
Ukadaulo wa SMD umagwirizana bwino ndi zolinga zokhazikika: zida zake zomwe zimasinthidwa zimachepetsa zinyalala zamagetsi, pomwe kugwiritsa ntchito mphamvu zochepa kumachepetsa zizindikiro za mpweya. Kwa ogwiritsa ntchito, kuthekera kosintha mikanda payokha (monga kusintha kuchokera ku mitundu yoyera yofunda kupita ku kuwala kwa masana) kumawonjezera kusinthasintha popanda kusintha chogwirira chonse, zomwe zimapangitsa nyali za SMD kukhala chisankho chanzeru komanso chosinthika m'malo okhala amakono.
