Ukuma kwe-SMD kwamaSurface Agibele ngaphezulu. Ukuholwa ngakunye kwe-SMD kufaka phakathi i-1 LED Chip

I-COB imele i-chip ebhodini, i-1 COB ifaka i-chip eminingi ye-LED.

Izibani ze-SMD zakhiwa ngamaphoyinti amaningi akhanyayo. I-SMD ijwayele ukusebenzisa ukukhanya okugungxayo.

Isibani se-COB singumthombo wokukhanya ongaphezulu onephuzu elilodwa kuphela elikhanyayo. I-COB imvamisa isebenzisa ukukhanya kwendawo nge-engeli ethile.
