Ubwino wa COB LED
Ukadaulo wa COB LED (chip-on-board LED) umakondedwa chifukwa chakuchita bwino kwambiri pazinthu zambiri. Nawa maubwino ena a COB LEDs:
• Kuwala kwambiri komanso kugwiritsa ntchito mphamvu moyenera:COB LED imagwiritsa ntchito ma diode angapo ophatikizidwa kuti apereke kuwala kokwanira kwinaku akugwiritsa ntchito mphamvu zochepa pomwe akupanga ma lumens ambiri.
• Kapangidwe kakang'ono:Chifukwa cha malo ocheperako otulutsa kuwala, zida za COB LED ndizophatikizana, zomwe zimapangitsa kuti lumen ichuluke pa sikweya sentimita/inchi.
• Mawonekedwe ozungulira osavuta:COB LED imayatsa ma diode tchipisi angapo kudzera panjira imodzi yolumikizira, kuchepetsa kuchuluka kwa magawo ofunikira ndikuchepetsa magwiridwe antchito.
• Ubwino wotentha:Kuchepetsa kuchuluka kwa zigawo ndikuchotsa zopangira zachikhalidwe za LED chip kumathandizira kuchepetsa kutentha, kuchepetsa kutentha kwa gawo lonse, kuwonjezera moyo wautumiki ndikuwongolera kudalirika.
• Kuyika kosavuta:Ma LED a COB ndi ophweka kwambiri kuyika muzitsulo zakunja za kutentha, zomwe zimathandiza kusunga kutentha kochepa pa msonkhano wonse.
• Kumveka bwino komanso kuchita bwino:COB LED, chifukwa cha kufalikira kwa dera lalikulu, imapereka malo okulirapo, kuwongolera kumveka bwino komanso mphamvu zowunikira.
• Kuchita zolimbana ndi zivomezi:COB LED imawonetsa magwiridwe antchito abwino kwambiri odana ndi seismic, ndikupangitsa kuti ikhale yokhazikika komanso yodalirika pamachitidwe osiyanasiyana ogwiritsira ntchito.
Kuipa kwa COB LEDs
Ngakhale ma LED a COB ali ndi zabwino zambiri, alinso ndi malire:
• Zofunika Mphamvu:Mphamvu yamagetsi yakunja yopangidwa mwaluso imafunika kuti ipereke mphamvu zokhazikika komanso magetsi komanso kupewa kuwonongeka kwa diode.
• Kapangidwe ka sink ya kutentha:Masinki otentha ayenera kukonzedwa mosamala kuti apewe kuwonongeka kwa ma diode chifukwa cha kutentha kwambiri, makamaka potulutsa mafunde owunikira kwambiri pamalo ochepa.
• Kukonza kochepa:Nyali za COB za LED zili ndi kukonzanso kochepa. Ngati diode imodzi mu COB yawonongeka, LED yonse ya COB nthawi zambiri imayenera kusinthidwa, pomwe ma SMD LED amatha kusintha magawo omwe awonongeka payekhapayekha.
• Zosankha zamitundu zochepa:Zosankha zamitundu yama COB LED zitha kukhala zochepa poyerekeza ndi ma SMD LED.
• Mtengo wokwera:Ma COB LED nthawi zambiri amawononga ndalama zambiri kuposa ma SMD LED.
Ntchito zosiyanasiyana za COB LEDs
Ma LED a COB ali ndi ntchito zosiyanasiyana, kuyambira kunyumba mpaka ku mafakitale, kuphatikiza koma osachepera:
•Monga zowunikira zolimba (SSL) m'malo mwa mababu achitsulo a halide mu magetsi a mumsewu, ma bay bay, zowunikira zotsika ndi zowunikira zapamwamba.
•Zowunikira zowunikira za LED zipinda zochezera ndi maholo chifukwa cha makulidwe awo akulu.
•Malo monga mabwalo amasewera, minda kapena mabwalo akulu omwe amafunikira kuwala kowala usiku.
•Kuunikira koyambira panjira ndi makonde, kusintha kwa fulorosenti, magetsi a LED, mizere yowunikira, kuwala kwa kamera ya smartphone, ndi zina zambiri.
