NikiChip-on-Board (“COB”) LED?
Chip-on-Board cyangwa “COB” bivuga gushiraho chip yambaye LED yambaye ubusa ihuye na substrate (nka karubone ya silicon cyangwa safiro) kugirango itange imirongo ya LED. LEDs ya COB ifite inyungu nyinshi kurenza tekinoroji ya LED ishaje, nka Surface Mounted Device (“SMD”) LEDs cyangwa Dual In-Line Package (“DIP”) LED. Ikigaragara cyane, tekinoroji ya COB ituma ubwinshi bwo gupakira ibintu byinshi bya LED, cyangwa icyo abashinzwe urumuri bavuga ko ari "ubucucike bwa lumen". Kurugero, ukoresheje tekinoroji ya COB LED kuri 10mm x 10mm kare ya array ibisubizo bivamo inshuro 38 LED ugereranije na tekinoroji ya DIP LED hamwe na LED inshuro 8.5 ugereranijeSMD LEDikoranabuhanga (reba igishushanyo gikurikira). Ibi bivamo imbaraga nyinshi nuburinganire bwumucyo. Ubundi, gukoresha tekinoroji ya COB LED birashobora kugabanya cyane ikirenge hamwe ningufu zikoreshwa rya LED murwego rwo gukomeza urumuri ruhoraho. Kurugero, 500 lumen COB LED array irashobora kuba inshuro ntoya kandi igakoresha ingufu nke ugereranije na 500 lumen SMD cyangwa DIP LED Array.
