Led or cob
NettetA chip-on-board (COB) LED is a multi-die LED package in which an array of diodes are directly mounted and electrically interconnected onto a metal-core printed circuit board (MCPCB) or a ceramic substrate. The die matrix is then coated with an organic polymer containing a yellow phosphor. COB LEDs are high power packages that combine high … NettetTaking a 10mm x 10mm square LED array as an example, you would only fit 9 DIP LEDs on the square. You would fit 342 COB LEDs in the same space, though, so you can …
